Abstract
The invention discloses a dust removing and deodorization process and device for a tail gas generated at a starch production section. The process comprises the following steps: collecting gases with odor in a sealing system in the starch production process; and delivering the gases in the sealing system to an elution tower through a collection air port, a delivery air pipe and a fan to be subjected to dust removing and deodorization processing therein, wherein an alkaline solution of a certain concentration is in the elution tower so as to capture dust and malodor particles in the gases, thereby achieving the purposes of dust removal and deodorization. Compared with the prior art, the device and the process have the characteristics of energy conservation, environmental friendliness, and the like, can be widely used in fermentation, chemical engineering, and food industries, and has a good popularization and application value.
Description
Technical field
The invention belongs to the Starch Production field, be specifically related to a kind of starch workshop section's tails dedusting deodorization process and device.

In Starch Production workshop section, the generation of gas with foreign flavor mainly is fiber, albumen powder, plumule baking operation.Gas with foreign flavor improvement is the difficult problem in the Starch Production always, often investment is larger, technique is numerous and diverse, regulation effect is undesirable, produce secondary pollution, the ambient influnence around the production plant area is difficult to control, especially the resident's of periphery life caused larger impact, can't guarantee pollution-freeization of Starch Production, be a problem to Starch Production.
Summary of the invention
One of purpose of the present invention provides the method for tails dedusting deodorizing in a kind of Starch Production.
Two of purpose of the present invention provides the device of tails dedusting deodorizing in a kind of Starch Production.
Technical scheme of the present invention is as follows:
A kind of starch workshop section tails dedusting deodorization process, step is as follows:
A, the tail gas that produces from starch workshop section are collected into the airtight air accumulator by tail gas collecting device;
Gas in B, the air accumulator is sent into wash-out in the wash-out tower by pipeline;
C, reaction cleaning solution later reclaim by the cleaning solution recycling can, and be recycling, do not efflux, and the gas that meets discharge standard effluxes by exhaust outlet.
Described starch workshop section tails dedusting deodorization process, preferred scheme is that contain cleaning solvent in the described wash-out tower of step B, cleaning solvent is alkaline solution.Preferred scheme is that described alkaline solution is NaOH, potassium hydroxide or calcium hydroxide aqueous solution.Be more preferably, described alkaline solution is that NaOH, potassium hydroxide or calcium hydroxide and water are according to the preferred 8:1 of 6-10:1() part by weight formulated.
The present invention also provides a kind of starch workshop section tails dedusting odor removal, it mainly comprises tail gas collecting device, air accumulator, wash-out tower and cleaning solution recycling can, described tail gas collecting device links to each other with the wash-out tower with air accumulator by pipeline, described wash-out top of tower is provided with exhaust outlet, and the discharge opeing outlet of described wash-out tower is connected with the cleaning solution recycling can.
Described starch workshop section tails dedusting odor removal, preferred scheme is that described cleaning solution recycling can is connected with the discharge opeing import of wash-out tower by pump.
The present invention is to provide a kind of starch workshop section's waste gas dedusting deodorization process and device, to produce tail gas in the starch production process, collect in the closed system by gathering-device, then send in the wash-out tower, process, reach the purpose of dedusting deodorizing, step is as follows: 1, with the tail gas that produces in the starch production process, collect in the closed system; 2, by collecting the air port, carrying airduct and blower fan, with the foul smell in the sealing system, be sent to and carry out the deodorizing processing in the wash-out tower; 3, the cleaning solvent (alkaline solution) that contains in the wash-out tower is caught the flue dust in the gas and stench particle, carries out smoke abatement and deodorizing; 4, without the stench taste on the sense organ, reduced the diffusion zone of gas with foreign flavor in the gas that discharges after the improvement.
Technical advantage of the present invention is:
(1) energy-conservation: operation is simple, equipment is less, so can reduce the consumption of the electricity in the governance process;
(2) water saving: the alkali lye reusable edible in the wash-out tower, reduce the consumption of water resource;
(3) after the oven dry treating tail gas was administered, when having protected environment, environment, the social benefit of enterprise got a promotion;
(4) technique simple, be easy to realize successful.
