Description
Technical field
The present invention relates to a kind of hot air distribution device, specifically a kind of spray drying tower hot air distribution device, belong to dry
Dry technical field.
Background technology
The application field of dry technology was more and more extensive in recent years, in addition to traditional food, medicine and other fields, environmental protection
Also applied in field.With the aggravation of environmental pollution, environmental standard is strict all the more, and national requirements coal-burning power plant is to desulfurization wastewater
Deng progress zero discharge treatment, there is scholar's research to set up the evaporation process that single drying tower carries out desulfurization wastewater.The method requirement
The part heat smoke introduced before air preheater, fully contact being evaporated with desulfurization wastewater, evaporation product is trapped by electrostatic precipitator.
Generally, hot blast is needed after hot air distribution device is uniformly distributed, and could enter spray drying tower.Hot blast
The effect of distributor is uniformly to provide the heat required for range drying, controls route that droplet and particle are passed through and quick
Ground is removed by the moisture of evaporation from range of atomization.
In use, the problem of hot blast skewness, air outlet be present with hot air distribution device in existing drying tower
Hot blast speed and direction are bad, cause material uniformly to be mixed with hot blast, the problems such as so as to cause to dry insufficient or viscous wall
The content of the invention
The technical problem to be solved in the invention is to provide a kind of spraying simple in construction, that hot blast can be made to be evenly distributed and done
Dry tower hot air distribution device.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of spray drying tower hot air distribution device, including three inversed taper platform shape housings being set with one heart, three inversed taper platforms
Shape housing is connected by top cover；Outside inversed taper platform shape housing upper is partitioned into air intake spiral case by cylinder, is uniformly set on cylinder
Put some blast pipe connection air intake spiral cases and the air channel being made up of outside inversed taper platform shape housing and middle part inversed taper platform shape housing；Water conservancy diversion
Plate is uniformly arranged on the bottom of the outer wall of middle part inversed taper platform shape housing；The inside inversed taper platform shape housing of installation centrifugal atomizer is located at
Middle part inversed taper platform shape enclosure interior；The air intake spiral case is connected with external air channel.
Further, the air inlet end of the blast pipe and air opening end are hypotenuse, the hypotenuse of air inlet end during installation
Face hot wind flow direction, air outlet are inclined to the bottom in air channel.
Further, the air intake spiral case and external air channel are tangent in junction.
Further, the regulating gate of control intake is set in the middle part of the blast pipe.
Further, described deflector one end sets an auricle, and deflector is screwed on middle part by auricle and fallen
On the outer wall of frustum shell, the adjustable angle of deflector and vertical direction.
Further, three inversed taper platform shape housing male cone (strobilus masculinus) tapers are identical.
By adopting the above-described technical solution, the technological progress that the present invention obtains is：
Hot blast is incorporated into air channel by some blast pipes in the present invention, passes through blast pipe and the tune of blast pipe upper lock gate
Section so that air intake is uniformly and downward spiral flows.
Present invention improves over deflector structure, is improved to the deflector of adjustable angle, can control into hot blast and enter drying
The angle of tower, so as to control the distribution characteristics of droplet group, prevent the generation of wall sticking phenomenon.
Air intake spiral case is changed to cross-sectional area equal air channel everywhere in the present invention, so can ensure air intake spiral case everywhere
Blast is equal, and hot blast is more uniform when entering air channel by blast pipe.
External air channel and the tangent connection of air intake spiral case, can make hot blast tangentially enter air intake spiral case, so as to protect in the present invention
Demonstrate,proving hot blast has higher wind speed and the unification of hot wind flow direction.

Embodiment
The present invention is described in further details with reference to embodiment：
As shown in figure 1, the present invention includes three inversed taper platform shape housings being set with one heart, three inversed taper platform shape housings are used
Top cover 13 is connected；Air intake spiral case 3 is partitioned into by cylinder 12 on the outside top of inversed taper platform shape housing 4, and on cylinder 12 uniformly
The blast pipe 1 of some adjusting air inlet amounts is installed, blast pipe 1 is connected air intake spiral case 3 and by outside inversed taper platform shape housing 4 with
The air channel 11 that portion's inversed taper platform shape housing 5 forms；Deflector 7 is uniformly arranged on to the bottom of the outer wall of middle part inversed taper platform shape housing 4；
The inside inversed taper platform shape housing 6 for being provided with centrifugal atomizer 8 is arranged in middle part inversed taper platform shape housing 5；External air channel 10 with
Air intake spiral case 3 is connected, in order that outside hot blast can keep very fast wind speed even into the hot air distribution device, external air channel
10 is tangent in junction with air intake spiral case 3, and hot blast tangentially enters air intake spiral case 3, as shown in Figure 2.
The mode that hot blast is entered to hot air distribution device in the present invention is improved, some using being installed on cylinder 12
The mode of blast pipe 1, connection air intake spiral case 3 and air channel 11.The structure of blast pipe 1 is as shown in figure 3, air inlet end and air opening end
Hypotenuse is processed into, makes the direction of the hypotenuse face hot wind flow of air intake when mounted, blast pipe 1 is in tilted layout and makes air outlet
The bottom in air channel 11 is inclined to, is arranged so as to that hot blast can be made helically to flow downwards in air channel 11.In order to better control over into
Air quantity has installed regulating gate 2 additional on blast pipe 1, and regulating gate 2 is controlled using long distance electricization.It can be controlled using above-mentioned design
The air quantity of heating wind makes hot blast distribution more uniformly flow downward in the shape of a spiral.Air intake spiral case 3 in present invention cross section everywhere
Product is identical, can ensure that air pressure is identical everywhere during use, hot blast is entered outside inversed taper platform shape housing 4 and middle part inversed taper platform shape shell
It is more uniform and stable during the air channel 11 that body 5 surrounds.
The present invention is improved the structure and mounting means of deflector 7, and one is provided with one end of deflector 7 admittedly
Surely the auricle 9 connected, concrete structure is as shown in Figure 4, Figure 5.Deflector 7 is screwed in middle part inversed taper platform by auricle 9
On the outer wall of shape housing 5 and angle is adjusted, the angle of deflector 7 and vertical direction can adjust as needed, so can be with
Wind speed and rotation mist square size are suitable when the hot blast is entered drying tower by the bottom in air channel 11, it is ensured that droplet even drop down is simultaneously
Fully dry.
The present invention is arranged on to the top of spray drying tower during use, external air channel 10 is connected with air intake spiral case 3, will
Desulfurization wastewater introduces centrifugal atomizer 8, and drying tower is entered after atomizing.Hot blast is from external air channel 10 tangentially into hot blast point
With device, by the distribution of hot air distribution device, hot blast can be made equably spirally to be entered by the bottom in air channel 11 downwards
Drying tower, with needing dry droplet fully to be contacted, complete dry heat and mass transfer process.Hot blast is led through deflector 7
Stream uniformly moves downward at the appropriate speed in drying tower, can both ensure that droplet is fully dried, and to greatest extent
Avoid the generation of glutinous wall, glutinous top phenomenon.
