Description
Technical field
The utility model relates to a kind of equipment being applicable to the process of polytype chemical laboratory waste gas.
Background technology
In China, fuel combustion, the discharge of industrial waste gas is the main source of atmosphere pollution, till now, these pollutions have caused great harm, in a lot of local factory, laboratory, waste gas is not just directly discharged in air through any process, some enterprises or factory, although take certain processing mode to waste gas, but do not reach the discharge standard of national requirements, even the laboratory of some developed regions, the waste gas discharged is usually just just discharge after process in simple reduction of fractions to a common denominator cupboard also, in outlying district, some large-scale chemical plant, smeltery, laboratory, then any process is not done to waste gas at all, this brings great infringement to the life and health of employee and the local common people, consequence is extremely serious.
In sum, exhaust-gas treatment mode general at present has not met the requirement of national development, can not meet the demand of people ' s health, therefore, develop the clean waste gas processing method of a kind of safety and sanitation and equipment particularly important.
Summary of the invention
The purpose of this utility model is to provide a kind of reached dusty gas zero comprising chalk dust removing, acidity, alkalescence, neutral soluble and soluble waste gas and exceeds standard the equipment of process of chemical laboratory waste gas.
The technical solution of the utility model is: a kind of equipment of chemical laboratory exhaust-gas treatment comprises: include the fume hood of sponge, the first alkali lye countercurrent spray tower and the second alkali lye countercurrent spray tower, alkali lye circulatory pool, the first circulating pump and the second circulating pump, the first centrifugal blower and the second centrifugal blower, high efficiency active carbon adsorption tower; The fume hood including sponge connects the first alkali lye countercurrent spray tower, first alkali lye countercurrent spray tower is connected with the second alkali lye countercurrent spray tower by the first centrifugal blower, first alkali lye countercurrent spray tower is connected with alkali lye circulatory pool with the second circulating pump respectively by the firstth circulating pump with the second alkali lye countercurrent spray tower, second alkali lye countercurrent spray tower is connected with high efficiency active carbon adsorption tower by the second centrifugal blower, high efficiency active carbon adsorption tower is connected to checkout gear, and checkout gear is connected with the first alkali lye countercurrent spray tower again.
The utility model has the advantages that: comprise twice alkali lye counter current absorption tower, can acid, alkaline and neutral soluble gas be removed more thorough, add high efficiency active carbon adsorption tower, can insoluble residual air process be obtained cleaner.By multi-layer circular treatment and test and monitoring timely, zero discharge beyond standards of pollution gas can be realized.
Accompanying drawing explanation
Fig. 1 is chemical laboratory waste gas treatment equipment schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1: equipment of the present utility model is: fume hood 1, the first alkali lye countercurrent spray tower 2 and the second alkali lye countercurrent spray tower 7 that include sponge, alkali lye circulatory pool 3, first circulating pump 4 and the second circulating pump 6, first centrifugal blower 5 and the second centrifugal blower 8, high efficiency active carbon adsorption tower 9 and checkout gear 10; The fume hood 1 including sponge connects the first alkali lye countercurrent spray tower 2, first alkali lye countercurrent spray tower 2 is connected with the second alkali lye countercurrent spray tower 7 by the first centrifugal blower 3, first alkali lye countercurrent spray tower 2 is connected with alkali lye circulatory pool 3 with the second circulating pump 6 respectively by the firstth circulating pump 4 with the second alkali lye countercurrent spray tower 7, second alkali lye countercurrent spray tower 7 is connected with high efficiency active carbon adsorption tower 9 by the second centrifugal blower 8, high efficiency active carbon adsorption tower 9 is connected to checkout gear 10, and checkout gear 10 is connected with the first alkali lye countercurrent spray tower 2 again.
The fume hood containing sponge described in the utility model, the first alkali lye countercurrent spray tower and the second alkali lye countercurrent spray tower, alkali lye circulatory pool, the first circulating pump and the second circulating pump, high efficiency active carbon adsorption tower and checkout gear all can adopt existing equipment and prior art to make.
The method of the waste gas produced with above-mentioned device processes chemical laboratory is:
Waste gas, through the fume hood 1 of included sponge, goes out dust contained in waste gas by the suction-operated of sponge; Gas after sponge dedusting, be directed in one-level alkali lye countercurrent spray tower 2, by circulating pump 4, by the NaOH solution of the mass concentration 10% in alkali lye storage pool 3 from one-level alkali lye countercurrent spray tower 2 top spray, remove most of sour gas and solvable alkaline neutral gas; Residual air imports in secondary alkali lye countercurrent spray tower 7 via blower fan 5, by the processing mode same with one-level alkali lye countercurrent spray tower 2, and more soluble gas in removing residual air; Remaining gas imports in high efficiency active carbon adsorption tower 9 through centrifugal blower 8 and allows high efficiency active carbon adsorb, the gas sample of adsorbing through high efficiency active carbon is detected, namely discharge after up to standard, not up to standard then through circulating fan 10 exhausting in one-level countercurrent spray tower 2, carry out circular treatment, until detect qualified rear discharge, through this circular treatment and timely test and monitoring, pollution gas discharge zero can be reached and exceed standard.
