Abstract
The invention relates to an organic fertilizer aerobic fermentation odor treatment method. The method comprises the following steps of: collecting odor generated in a production process of an organic fertilizer by using a gas-collecting device and then inputting the odor to a gas transportation channel provided with a swirl vane so as to change the moving direction and the flow speed of the odor; when the flow speed of the odor reaches more than 15m/s, allowing the gas to enter a vertical wind tunnel of which the bottom is provided with an accelerating impeller to increase the speed to be more than 25m/s; under the strong impact disturbance of an aerodynamic force, atomizing a removing agent, wherein the upper part of the vertical wind tunnel is provided with a removing agent spraying device; at the same time, forming a turbulent flow boundary layer on the wall of the wind tunnel; fully mixing the odor and the removing agent and performing a chemical and physical reaction of the odor and the removing agent; discharging the generated neutral solid granules and the reused solution to a sedimentation tank along the tunnel wall under the action of the gravity; and discharging the purified gas from an exhaust outlet at the top of the tunnel.
Description
Technical field
The present invention relates to the technical field of air contaminant treatment in the environmental conservation.It is primarily aimed at is fertilizer factory when making good use of the aerobe fermentation mode and producing, to the processing method of the foul smell that produces in the sweat.
Background technology
Existing organic fertilizer production adopts the mode of aerobic fermentation to produce fertilizer mostly.In the aerobic fermentation process, can produce a large amount of foul smell that contains multiple compound compositions such as hydrogen sulfide, ammonia, sulfur dioxide.Adopt the deodorizing method of convection current washing and absorption at present mostly for the processing of these foul smell.
The method of convection current washing is to rely on foul smell relative with detergent mobile in washing facility from bottom to top from top to bottom, and reach the admixture of gas, liquid, the agent generation Chemical Physics that removes in admixture in the different components of foul smell and the detergent is reacted, produce neutral solid particle, stink substance is removed, and purified gas is discharged.
Adsorption method is that foul smell is drawn into the gas discharge channel that adsorbent is housed, and when gas passes through the passage of certain-length, adsorbent will have the material absorption of stink, and gas is purified to a certain extent.
Above-mentioned two kinds of methods all exist bigger limitation.
The defective of convection current washing method is: because foul smell is the bulk ascending motion, detergent liquid is the wire descending motion, in convection process up and down, just have undercompounding, reaction not exclusively removes the not high problem of stink substance efficient, and equipment volume is big, the operating cost height.
The defective of absorption method is: owing to be subjected to the restriction of adsorbents adsorb ability, reach adsorption effect preferably, just must strengthen the input amount of adsorbent and prolong sorption channel as far as possible, processing cost is huge.
Summary of the invention
The objective of the invention is to: provide a kind of odor removal efficient height, the odor treatment method that operating cost is low.Be mainly used in the processing of the foul smell that produces in the organic fertilizer aerobic fermentation process.
Technical scheme
Above-mentioned purpose of the present invention, can realize by following technological facilities:
The foul smell that produces in the organic fertilizer production process is collected with gas collecting apparatus, and foul smell is sucked gas distribution channel, establish swirl vane in the passage, be used to change the direction of motion of foul smell, improve the flowing velocity of foul smell by air-introduced machine.When the speed of foul smell reaches 15 meter per seconds when above, enter vertical wind tunnel, the wind-tunnel bottom is provided with speeding-up blade.Gas enters back speed and brings up to more than 25 meter per seconds, be provided with on wind-tunnel top and remove the agent flusher, under the powerful shock vibration of aerodynamic force, remove agent and be atomized, simultaneously form turbulent boundary layer at the hole of wind-tunnel wall, foul smell with remove the biochemical physical reactions of agent hybrid concurrency, neutral solid particle that produces and the solution that recycles, Dong Bi drains into sedimentation tank in the effect lower edge of gravity, purified gas, the air vent discharging through the top, hole.
Description of drawings
Fig. 1 is the odor removal sketch map among the present invention.
Shown in the figure: 1 gas pipeline 2 quickens impeller 3 vertical wind tunnels 4 flushers 5 air vents 6 observation windows
The specific embodiment
Below in conjunction with the running experiment of implementing and with reference to sketch map, provide the specific embodiment:
At first the foul smell of collecting is sucked in the gas distribution channel (1) by air-introduced machine, owing to be provided with swirl vane in the passage, gas rotation and quickening flow velocity under the effect of tangent line, when the mobile speed of foul smell reaches 15 meter per seconds when above, foul smell enters vertical wind tunnel (3), under the effect of quickening impeller (2), the flow velocity of foul smell continues to improve, and can reach more than 25 meter per seconds.On the top of wind-tunnel, be equipped with and remove agent flusher (4).Under the powerful shock vibration of aerodynamic force, removing agent is atomized, form turbulent boundary layer at the hole of wind-tunnel wall simultaneously, foul smell with remove the biochemical physical reactions of the abundant hybrid concurrency of agent, neutral solid particle that produces and the solution that recycles, Dong Bi drains into sedimentation tank in the effect lower edge of gravity, purified gas, air vent (5) discharging through the top, hole.
Experimental result detects proof, the method applied in the present invention, and the removal efficiency that can make stink substance is more than 95%, and use equipment is simple, operating cost is low, energy resource consumption is few, emission gases is up to standard.
