Detailed description of the preferred embodiments
In the following some non-limiting examples of embodiments of the method and system of the invention are described.
The system of the invention is adapted for condensing compounds present in the fluid stream and for separating the condensed material from the condensation surface, based on changing the fluid stream flux velocity, and comprises basically the elements described in the following.
- The system is inserted in a closed volume, named "deposition stack", having a given shape, for example cylindrical shape, or parallelepiped shape or a custom non canonical shape.
- The deposition stack has at least a surface area that allows the fluid stream to enter in the volume and at least a surface area that allows the fluid stream to escape from it.
- The deposition stack has inside a hydraulic system that injects water or in general liquid chemical solution and releases the liquid from the entrance surface area.
- The deposition stack has inside a stack of layers that allow the fluid stream and liquid to pass through by window openings present on them.
- The hydraulic system is provided with spreading apertures, such as sprayers and/or nozzles and/or taps, which are present in between (inside) the layers, and preferably also on the lateral walls of the closed volume, adapted to spray water and/or liquid chemical solution inside the deposition stack, even in between the layers.
The stack of layers is preferably characterized by one or more of the following features:
- The surfaces of the layers can be planar (surfaces 21, ... . 2n in Figures 2, 3) or non-planar (surfaces 41, .... 4n in Figure 4)
In the stack the distance between neighboring layers is variable and controllable;
In the stack neighboring layers form an angle a such that 0 < a < 90°; the angle is determined and possibly varied depending on the statistical composition of the particles (for example pollutant particles) to be separated, in particular towards greater angles for higher percentages of particles to be diffused, (i.e. inorganic substances in a great industrial plant, PM1) towards smaller angles for higher percentages of particles to be impacted, as explained below.
The layers are hanged to the deposition stack by suitable supports configured so as to be controlled for setting the angles between neighboring layers. In a possible embodiment, the supports can be the bars described below.
The window openings Si (Figure 1) are preferably characterized by one or more of the following features:
The window openings have defined geometries even different among them, for example from circular to triangular geometry respecting the isoperimetric inequality;
The window openings are covered by a net, the net have a mash less than 5mm;
every surface (layer) contain at least one window opening;
- every surface (layer) can have window openings of diverse geometry;
disposition of window openings in a single layer can be irregular, even not copied in another layer of the same stack deposition; in successive layers the positions of the windows may be different.
The hydraulic system is preferably characterized by one or more of the following features:
- The spreading apertures (sprayers and/or nozzles and/or taps) are present in between (inside) the layers, and preferably also on the lateral walls of the closed volume. For example in Figures 2, 3 and 4 the sprayers and/or nozzles and/or taps are obtained on a number of bars (31, ...3m; 51, ...5m) inserted substantially longitudinally in the volume, and passing through the layers. By means of the sprayers and/or nozzles and/or taps, water or liquid chemical solution is sprayed inside the volume in between the layers, substantially for washing the surfaces of the layers, and preferably the lateral walls of the volume, and draining away the particles to be collected in the counter flow. The form of the spreading apertures is determined depending on the kind of fluid to be sprayed, so as to spray as much of the solution as possible on the overall surface of the layers, even on the lateral walls of the volume. The adjustable slope of the layers of the stack in the closed volume has the advantage of increasing the draining effect.
In the system two opposite flow directions are present: a counter flow of water or liquid chemical solution (Fig. 3), and a forward flow of fluid of droplets and gas with particles to be collected, so obtaining a wet mix of chemical solution and main flow and creating a thin humid film depositing on the surfaces of the layers and lateral walls of the volume. The particles to be separated are collected both by the droplets , as a precipitate by impact, and by the thin film depositing on the surfaces of the layers, and flowing in the counter direction.
The forward fluid of droplets is created by means of any suitable device in the area upstream of the deposition stack, with respect to the main flow direction.
A non-limiting example of device for creating the flow of droplets is described in the Italian patent application N°. MI2012A001893, filed on November 6th, 2012, in the name of the same applicant, which is hereby incorporated by reference in its entirety.
With reference to Fig. 6 (Figure 2 of the cited previous patent application), a closed liquid solution pumping system is shown, able to pump a liquid solution inside the closed volume, so as to create droplets, to flow from a manifold 109 inside the volume.
A number of tubes with sprayer 211 are distributed on the manifold, to spray the liquid and create the droplets, to mix with the gas containing the particles to be dropped, and create a fluid upstream of the layers of the deposition stack and passing through the latter with a given inlet velocity.
Inside the layers of the deposition stack a turbulence is created, all the particles are collected , all the droplets fall down on the internal surfaces of the volume, and downstream of the deposition stack the gas purified of the particles flows away, eventually with a given percentage of humidity, or without humidity, depending on the specific framework of application.
Preferably the chemical solution pumped for creating the droplets is of the same kind of that sprayed through the spreading apertures described above.
The system is adapted so as to control the relative velocity of the particles and droplets: by changing the distance between the layers the minimum flow velocity is controlled, i.e. the more the distance the lower the flow velocity; by changing the dimensions and positions of the window openings on the layers the maximum flow velocity is controlled, i.e. the lower the dimension of the window openings, the higher the maximum flow velocity.
Therefore it is possible to obtain a functional to be adapted depending on the kind of particles to be handled, also varying in the time, by controlling the distances and angles between the layers, and amount of diffusion process, described in more details below.
According to a qualified aspect of the invention, the adaptability is obtained acting on the geometrical parameters of the deposition stack, instead of the flow chemical compositions. The latter are substantially water solutions of catalyzing substances known per se, depending on the specific kinds of particles to be treated.
The particles to be treated are for example pollutant's particles, i.e. PM1....PM10, SOx, NOx, ozone , hydrocarbons, methane, benzene, etc...), and pollutants defined by law. In other cases, for example treatments for transformation of industrial streaming fluids or gases.
The system can be implemented by means of inert materials, for example polymers, or stainless steel, so as not to interfere with the process to be obtained.
The method of the invention is adapted for condensing compounds present in the fluid stream and for separating the condensed material from the condensation surface, based on changing the fluid stream flux velocity, and basically comprises steps as described in the following.
The deposition stack of the invention is adapted to collect particles (for example pollutant particles) in both liquid solution droplets present into the deposition stack and in the deposition stack surfaces. The size of liquid solution droplets is very small, i.e. droplets less than ΙΟμιη, able to flow into the deposition stack. These liquid solution droplets completely wet the total free surface of the deposition stack. Furthermore, there are several liquid solution injectors inside the deposition stack that assure the total surface wetting and wash it.
The particles are mainly collected by means of the impaction effect and the diffusion effect, described in more detail below.
More particularly, as far as the impaction effect is concerned, in the deposition stack the particles (in particular pollutant particles) tend to follow the streamlines of the fluid flow stream. However, when liquid droplets are introduced into the stream, the particles cannot always follow these streamlines as they diverge around the liquid chemical solution droplets. Due to the particle's mass, they break away from the streamlines and impact the droplets.
Impaction effect increases as the diameter of the particles increases, and as the relative velocity between the particles and droplets increases.
As particles get larger they are less likely to follow the fluid flow streamlines around droplets. Also, as a particle moves faster relative to the liquid droplet, there is a greater chance that the particle will hit a droplet. Impaction is a very effective collection mechanism in the deposition stack, in particular for fluid flow having stream velocities greater than 0.3m/s.
In this range of stream's velocity, particles of larger diameter, i.e. having diameters greater than
Ι .Ομιη, are collected. Impaction also increases increasing the density of liquid solution droplets. Likewise for the impaction effect on the droplets, there is the impaction on the total surface of the deposition stack. A thin film of liquid chemical solution is present on the deposition stack total surface. Then all the particles impacting the surface are collected.
As far as the diffusion effect is concerned, very small particles (in particular pollutant particles less than 0.1 μιη in diameter) experience brownian motion, random movement in fluid flow stream. These particles are so tiny that they are bumped by fluid flow molecules as they move in the fluid flow stream. The bumping causes them to move randomly in different ways, or to diffuse through the fluid flow. This irregular motion can cause the particles to collide with droplets and to be
collected. Because of this, diffusion, like impaction, is very effective in collection mechanism in deposition stack, in particular for particles smaller than 0.1 μιη.
The rate of diffusion depends on relative velocity between particles and liquid solution droplets and liquid chemical solution droplet diameters.
Likewise for the diffusion effect on the droplets, there is the diffusion on the total surface of the deposition stack. A thin film of liquid chemical solution is present on the deposition stack total surface. Then all the particles diffusing to the surface are collected by the thin film of liquid chemical solution.
For both impaction and diffusion effects, collection efficiency increases with an increase in relative velocity and a decrease in liquid droplet size.
Main characteristic of the deposition stack of the invention is the use of both effects referred to impaction on droplets and diffusion on large surface thin liquid film.
Another characteristic, as the relative velocity is a fundamental parameter for particles collection, is the peculiarity of the deposition stack able to obtain variable flow velocity through the entire deposition stack. Therefore it is possible to set-up the deposition stack in order to have the right functional of flow velocity able to collect specific particles just by setting the right flow velocity functional. In addition it is possible to collect different species of particles by setting a suitable flow velocity functional.
An example of flow velocity functional is described in figure 5. This is the case of isotropic deposition stack where the maximun flow velocity is constant and the minimum flow velocity too. In the described deposition stack it is possible to produce unnumerable diverse flow velocity functionals.
The functional parameters Vmax and Vmin in figure 5 represent absolute maximum and minimum velocities; in the most used configuration there are several relative minimum velocities Vmin and several relative maximum velocities Vmax, depending on the kind of particles to be treated.
Acting on the dimension of window openings it is possible to set the relative Vmax, while acting on the distance of consecutive layers it is possible to set the relative Vmin. These settings permit to affect in a precise mode the targeted particles and, at the same time, to have a large number of particles treated and collected.
Therefore different parameters can be set along the various layers depending on the variance of the particle's dimensions.
The general principles of the method for condensing compounds present in the fluid stream and for separating the condensed material from the condensation surface, based on changing the fluid
stream flux velocity, subject of the invention are the following.
Let's say S and P respectively the area and the perimeter of the generic window opening, in Figure 1 we have as example window openings with area Si and perimeter
¾+bi+Ci. Then the following isoperimetric inequality must be true:
4π& < R2
Let's say A the area of a generic single layer of the deposition stack, in Figure 1 we have an example of a generic layer with area A and perimeter P=a+b+c+d+e+f+g. Then the following inequality must be true:
The method and system of the invention is applicable generally in a variety of devices, for example those known as wet scrubbers.
Generally scrubbers are streaming gas control devices that can be used to remove pollutant compounds and/or gases from industrial exhaust streams. For example air scrubber for removing carbon dioxide from the air .
Further implementation details will not be described, as the man skilled in the art is able to carry out the invention starting from the teaching of the above description.
Many changes, modifications, variations and other uses and applications of the subject invention will become apparent to those skilled in the art after considering the specification and the accompanying drawings which disclose preferred embodiments thereof. All such changes, modifications, variations and other uses and applications which do not depart from the scope of the invention are deemed to be covered by this invention.
For example the main application of the system is in vertically oriented closed volumes and main flows, however any other orientation is possible, even horizontal.
The elements and characteristics described in the various forms of preferred embodiments can be mutually combined without departing from the scope of the invention.
