Description

(54) HYDRODYNAMIC DUST TRIMMER

one

The invention relates to the purification of industrial emissions into the atmosphere and can be used in the metallurgical, chemical, construction and other industries where gas emissions contain dust of any dusts and gases of any concentration.

Dust-and-gas-cleaning filters of various designs, Q, intended for wet cleaning of emissions are known and widely used in various fields of sawing.

A device for wet cleaning is known; gas containing a cylindrical or pus, gas inlet and reflux nozzles, turbu-fusers and housings are aligned with an axial cup with a conical bottom equipped with a device for displacing the cup in a vertical direction 20

In the operation of this hydrodynamic dust and gas separator, there may be a breakdown of the stable work process, which negatively affects the rhythm of its work, as well as the reliability and efficiency of its use in various working conditions. The filter is structurally complex and its performance deteriorates due to the need to use moving parts, and the presence of head slots does not ensure the collection of dust with a high dispersion of individual fractions.

Closest to the proposed technical essence and the achieved result is a hydrodynamic dust and gas trap, comprising a housing; with a gas supplying nozzle directed perpendicularly to the surface of the liquid, in the lower part of which a nozzle in the form of arcuate blades is installed; the foam-forming grid f21 is installed above the gas supplying nozzle.

The disadvantage of this device is the narrow limit of operation in speeds. low specific air load and high splashes. The purpose of the invention is a performance trap and an increase in the specific air load. The goal is achieved by the fact that a hydrodynamic dielectric separator comprising a body with a directional perpendicular to the surface, liquid gpcpodvodm pipe, in the lower part of which a swirling nozzle is installed in the form of arc-shaped blades, and a headpiece is installed over the gas supply pipe, a headpiece is installed. it is fitted with a coaxial insert attached to the grille at the bottom of the casing at. This blade is perforated. FIG. Figure 1 shows a general viewer; in fig. 2 - twist yusha nozzle; in fig. 3 is a section AA in FIG. 2 A hydrodynamic gas pressure trap comprises a housing 1, in the lower part of which a hopper 2 is located, filled with water. Inlet 1 is provided with an inlet 3, which serves to supply a gas-dust-air mixture. The inlet 3, at the end of which the swirling nozzle 4 is installed, is directed perpendicularly to the water surface in the bunker 2. Above the water surface in the bunker 2 and with the nozzle 4 the foam spraying grille 5 is installed. At the level of the foam-forming grille 5, holes 6 are made for removal polluted water foam along the drain 7 into the hopper 2. In the upper part of the housing 1 there is an outlet 8. The swirl nozzle 4 contains arcuate blades 9 with perforation 10 over the entire surface. Hydrodynamic pull trap works as follows. An inlet nozzle 3, a dust and gas / air mixture that hits the surface of the water into the bunker 2 at high speed, forms a funnel, creating a mixture of water foam and air and air mixture, which makes the tangential rotation of the air mixture and rotation of the air mixture and create a swirling nozzle and create the air mixture. , turbulent structure of the power supply of DUST particles and gas. The process of the gas-catchering process takes place according to the following scheme: the impact of a jet of dust from an air mixture supplied through a branch pipe to the surface of the water in the bunker ensures the capture of a large fraction of dust; The creation of a tangential rotation of the supplied air-fluid mixture passing through the perforated blades of the swirling nozzle of the nozzle and once in the bunker stimulates the separation process, increases the efficiency of dust and gas trapping, further along the motion of the air-fluid mixture, the flow particles intersect, after the impact on the water surface, part of the tangential flow, which creates a highly turbulent volume in which dust and gases are trapped; water on the foam created by the grate allows to capture the remaining fine dust and gas particles. The technical and economic effect from the use of the proposed invention is expressed in the efficiency of the wet gas collection in comparison with the known ones that operate only in the foam mode, as well as in the life of the fan located in the scheme, after the wet drawing gas processing in connection with a significant reduction in the size of the fan size, after a wet drawing and gas processing in connection with a significant reduction in the amount of the fan size, after a wet drawing gas processing in connection with a significant reduction in the size of the fan, after the wet drawing and gas trapping in connection with a significant reduction in the amount of the fan elusive dust falling into it, and reducing its unbalance. The invention The hydrodynamic gas catcher includes a housing with a gas inlet directed perpendicular to the liquid surface, in the lower part of which a swirling nozzle is installed in the form of arcuate blades, and foam is installed over the gas supply pipe (foam grille, which differs in the same). a chain of operating efficiency and an increase in the specific air load, the device is equipped with a coaxial insert mounted on the lower part of the case, attached to the p) The blades are perforated.
