Abstract
A dry-process sedimentation process suitable for odor treatment is characterized by including the steps of sending odor to a dry dust collector for dry-process sedimentation dedusting, sequentially sending treated gas to a primary washing and temperature reduction tower and a secondary washing and temperature reduction tower for washing and temperature reduction, sending the gas after washing and temperature reduction to a biological deodorization chamber through a draught fan, and discharging the gas after deodorization after dehumidification through an ion separation dehumidification and aerosol processor. The dry-process sedimentation dedusting includes that odor is introduced to a sedimentation chamber from the entrance of the sedimentation chamber; dust particles in the odor subside to the bottom of the sedimentation chamber along with the reduction of air velocity of the odor, flow into a screw conveyer of a discharging groove, and are discharged from an outlet of the conveyer, and treated gas enters the next treatment process from an outlet of the sedimentation chamber.
Description
Technical field
The present invention relates to a kind of odor treatment technology, relate to specifically a kind ofly can produce the dry method sedimentation process that is applicable to odor treatment that some gas with foreign flavor purify, administer being accompanied by in the industrial stoving process.
Background technology
In waste water of mgs slurry-spraying pelletizing production process, the large quantity of moisture in the slurries evaporates under the high-temperature hot-air effect and forms steam, has also produced a kind of gas with foreign flavor with aerosol character simultaneously.This gas with foreign flavor is made up of gaseous contaminant and particle.
At present, in the governance process to this gas with foreign flavor, the technological process of being adopted is not also sought unity of standard and regulation, and technological process (see figure 1) commonly used at present all is employing cleaning dust (1), multistage washing cooling (2,3); Biological deodorizing (5); The technological process of ion isolation dehumidifying and processing aerosol (6).
But in the gas with foreign flavor governance process, be an important step equally to the improvement of dust granules in the gas.In the slubbing operation of above-mentioned technological process; To the processing of dust granules thing, employing be " cleaning dust " technology (see figure 2), its process is: gas with foreign flavor is introduced the Venturi Scrubber (1) of dust removal by spraying from venturi inlet (8); Cooling water sprays from mouth spray (9); Collide with the gas with foreign flavor that has dust granules, the amounts of dust particle is brought in the cooling water, thereby reaches the pretreated purpose of dust.Gas after the processing gets into road treatment process (2) down from Venturi tube gas outlet (10).The dust granules that is removed is discharged from Venturi tube discharge outlet (11) with cooling water and is flowed into the cooling bay.The weak point of this operation is: in the dust granules processing procedure; The amounts of dust particle is brought in the cooling water; These dust granules get in the cooling bay with cooling water, and cooling water is caused severe contamination, also need contaminated cooling water is carried out after-treatment.
Summary of the invention
The object of the invention provides a kind of improvement technical scheme that is applicable to the employing dry method sedimentation process of odor treatment for dust granules in the gas with foreign flavor to existing weak point in the above-mentioned prior art just.
The object of the invention can be realized through following technique measures:
Dry method sedimentation process of the present invention comprises the steps: that earlier gas with foreign flavor being sent into dry collector advances dry method sedimentation dedusting; Gas after will handling is afterwards sent into I and II washing cooling tower successively and is washed cooling; Gas after the washing cooling is sent into the biological deodorizing chamber through air-introduced machine, and the gas after the deodorizing can enter atmosphere through the ion isolation dehumidifying and after handling the dehumidifying of aerosol step; Said dry method sedimentation dust removal step is following: earlier gas with foreign flavor is introduced expansion chamber from the expansion chamber inlet; In expansion chamber; Along with the reduction of gas with foreign flavor air velocity, the dust granules in the gas with foreign flavor is deposited to the expansion chamber bottom, flows in the conveying worm in the discharge groove; Discharge from the conveyer delivery outlet, the gas after the processing gets into road treatment process down from the expansion chamber gas outlet; After sedimentation, be processed that the dust granules pollutant more than 85% is eliminated in the gas with foreign flavor, thereby reach dust preliminary treatment purpose.
Beneficial effect of the present invention is following:
Because the dry method sedimentation process is in to the dust granules processing procedure, dust granules had just cleared before getting into washing cooling tower, thereby had avoided the severe contamination to cooling water, had reduced the expense to the improvement of cooling water; Moreover, can also directly be sent back to (in the slurry-spraying pelletizing production) by the dust granules that dry cleaning comes out and utilize, also reduce the expense when from water, extracting these dust granules.

The specific embodiment
To combine embodiment (accompanying drawing) to further describe below the present invention:
As shown in Figure 3; Dry method sedimentation process of the present invention adopts dry method sedimentation dedusting to replace cleaning dust step of the prior art; Specifically: technology of the present invention comprises the steps: that earlier gas with foreign flavor being sent into dry collector advances dry method sedimentation dedusting; Gas after will handling is afterwards sent into I and II washing cooling tower 2,3 successively and is washed cooling; Gas after the washing cooling is sent into biological deodorizing chamber 5 through air-introduced machine 4, and the gas after the deodorizing can enter atmosphere through chimney 7 through the ion isolation dehumidifying and after handling 6 dehumidifying of aerosol processor; Said dry method sedimentation dust removal step is following: earlier gas with foreign flavor is introduced expansion chamber 13 from expansion chamber inlet 12; In expansion chamber; Along with the reduction of gas with foreign flavor air velocity, the dust granules in the gas with foreign flavor is deposited to the expansion chamber bottom, flows in the conveying worm 15 in the discharge groove; Discharge from conveyer delivery outlet 16, the gas after the processing is the following road of 14 entering treatment process 2 from the expansion chamber gas outlet; After sedimentation, be processed that the dust granules pollutant more than 85% is eliminated in the gas with foreign flavor, thereby reach dust preliminary treatment purpose.
The housing of the dry collector described in the present invention (referring to Fig. 3) is that airtight rectangular structure (externally is sealing state; Must under the situation of not leaking gas with foreign flavor in the expansion chamber, can discharge heavy collection material smoothly); Described expansion chamber inlet 12 is arranged on the top of expansion chamber 13 1 ends; Expansion chamber gas outlet 14 is arranged on the side lower part of expansion chamber 13 other ends; The described conveying worm 15 that is arranged in the discharge groove is installed in expansion chamber bottom with the mode of being horizontally disposed with, in the expansion chamber above conveying worm 15 along its length, be provided with some upper and lower damping sheets with the mode that is provided with at interval.
