Description
Technical field
The invention belongs to belong to field of air purification device, more particularly to it is a kind of except haze device with circulation field abnormal shape ducting assembly and
Its manufacture method.
Background technology
As environmental pollution is increasingly severe, the pollution of air becomes severely afflicated area, the haze sky of China's most area
Number increases, and is not only that local outdoor air pollution is serious now, and the air in city entirety overhead has serious pollution, therefore empty
The purification of gas is paid attention to all the more by people.Haze, it is the portmanteau word of mist and haze.Haze is common in city.Chinese many areas will
Mist is incorporated to haze and carries out early-warning and predicting together as diastrous weather phenomenon, is referred to as " haze weather ".Haze is specific weather bar
Part and the result of mankind's activity interaction.The economy of high density population and social activities will necessarily discharge a large amount of fine particles,
Once discharge exceedes atmospheric air circulation ability and carrying degree, fine particle concentration is by continued accumulation, now if by quiet surely weather etc.
Influence, large-scale haze easily occur.Mist and haze something in common are all obstruction to vision things.The Crack cause and condition of mist and haze
But there is very big difference.Mist is swim skyborne a large amount of small water droplets or ice crystal, and formation condition will possess higher steam and satisfy
And factor.Fog seems gentle, and the inside includes but containing various harmful fine graineds, noxious material up to kind more than 20
Acid, alkali, salt, amine, phenol etc., and dust, pollen, acarid, influenza virus, tubercle bacillus, pneumococcus etc., its content are common
Tens times of air water droplet.Compared with mist, harm of the haze to the health of people is bigger.Due in haze tiny granular float
Particulate matter diameter directly can enter bronchus, or even lung typically below 0.01 micron by respiratory system.So haze shadow
Ring it is maximum be exactly people respiratory system, caused by disease be concentrated mainly on breathing problem, cranial vascular disease, nasal cavity inflammation etc.
In disease.Meanwhile during haze weather, air pressure reduction, Inhalable Particulate abruptly increase, air flow property are poor, harmful bacteria
Slowed with virus to what surrounding spread, cause virus concentration in air to increase, the risk of transmission is very high.At present, it is general
Although solved the problems, such as to a certain extent except haze, the air channel import of said apparatus generally existing all over the air cleaning unit used
Blast is small, and boundary resistance is big, except haze it is inefficient the problems such as.
The content of the invention
It is contemplated that a kind of ideal purification effect is provided in place of overcome the deficiencies in the prior art, air channel import blast
Greatly, boundary resistance is small, applied widely except haze efficiency high, compatibility it is strong except haze device with circulation field abnormal shape ducting assembly and
Its manufacture method.
In order to solve the above technical problems, what the present invention was realized in：
Except haze device circulation field abnormal shape ducting assembly, including expand air port, special-shaped air channel, axial flow blower and filter；Institute
The air outlet for stating expansion air port communicates through axial flow blower with the air intake vent in special-shaped air channel；The filter is fixed at special-shaped air channel
Air outlet；Expand air port and use bell-mouth structure of air.
As a kind of preferred scheme, special-shaped air channel 2X of the present invention, the cross-sectional close curve Gauss in tri- directions of Y, Z intends
Close function：
Parameter y to be estimated in formulamax、xmaxIt is respectively the peak value, peak and half width of Gaussian curve with S；
The closed curve that X1 axles section is formed is divided into 10 characteristic points, F (X1), F (X2), F (X3), F (X4), F (X5)
And F (X6) is variable coordinate；The mathematical modeling of each closed curve of X axis：
The closed curve that Y1 axles section is formed is divided into 8 characteristic points, G (Y1), G (Y2), G (Y3) and G (Y4) are variable
Coordinate；The mathematical modeling of each closed curve of Y-axis：
The closed curve that Z1 axles section is formed is divided into 7 characteristic points, K (Z1), K (Z2) and K (Z3) are variable coordinate；Z
The axially mathematical modeling of each closed curve：
It is above-mentioned except the manufacture method of haze device circulation field abnormal shape ducting assembly, the air outlet in air port will be expanded through axial flow blower
Communicated with the air intake vent in special-shaped air channel；Filter is set at the air outlet in special-shaped air channel；The special-shaped air channel X, tri- sides of Y, Z
To cross-sectional close curve using Gauss curve fitting structure mathematical modeling, and 3D models are constructed by SOLIDWORKS, through CFD
After calculating, related test parameters are simulated by FLUENT；Closed curve Gauss curve fitting function：
Parameter y to be estimated in formulamax、xmaxIt is respectively the peak value, peak and half width of Gaussian curve with S.
Ideal purification effect of the present invention, air channel import blast is big, and boundary resistance is small, applied widely except haze efficiency high, simultaneous
Capacitive is strong.
By adjusting air inlet structure, the wind for making to come in maximum secting area and can be uniformly distributed and pass through filtering the present invention.It is logical
Cross the wind that above axial-flow windwheel comes, adjustment air inlet structure and boundary-layer can be reached in this air channel, further adjust into
Wind wind direction and homogeneous state distribution, it can be joined with the bigger area of the resistance of minimum with filter below.To air channel import and
Its wind direction adjusting angle is handled, and has the circulation field air inlet of eddy flow, increases import blast of the present invention, while reduce gas
Boundary-layer coefficient (reduce boundary resistance) of the body in air channel kind.Due at wind inlet for supercharging deceleration area, fluid particle by
The differential pressure action opposite with main flow direction；For the particle of close wall because fluid viscosity acts on, speed will than at main flow center
It is much smaller；Under the collective effect of reverse differential pressure and viscous force, speed is gradually reduced, and in place's boundary-layer separation, then appearance
The flowing opposite with main flow direction produces vortex.For increaser, Reynolds number or the angle of flare are bigger, and vortex area scope is bigger,
Position is more forward；For sudden expansion, the size of Reynolds number plays a decisive role to vortex zone position and the influence unobvious of size
It is shape.Therefore, the method for optimizing divergent segment is mainly to destroy or the separation of delay boundary-layer, and reduces its intensity and big
It is small.
Different wind speed lower unit module ventilation amounts, intake and exhaust PM2.5/PM10 concentration tables

According to each profile of Z axis, successively for the characteristic and characteristic distributions of each curved surface, corresponding preferred coordinates are found out
Point, the Z1 profiles are air channel most top surface sectional view, are followed successively by Z2, Z3 downwards.There are 7 to have in K (Z1) top-sectional view
Imitate characteristic point, but pointed out recess in obvious (4,5,6) were last, its effect can adjust wind angle in eddy flow, make it
Next filter plant can be vertically blown into.With extending forward to bottom surface, make to come wind energy maximum area and filter plant
It is in contact, its closed surface coordinate is K (Z2), K (Z3).Showing that Z axis closes to each according to closed surface equation (1), solution
Close the mathematical modeling of curve.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
