Abstract
The invention relates to an adsorption bed with the controllable output concentration. The adsorption bed comprises an adsorption bed body, a desorption gas circulation outlet is formed in the adsorption bed body, the desorption gas circulation outlet is connected with an air inlet of an electric heater through a pipe, an air outlet of the electric heater is connected with an air inlet of a desorption gas circulation fan through a pipe, and an outlet of the desorption gas circulation fan is connected with a desorption gas circulation inlet in the adsorption bed body. According to the adsorption bed, the technology assumption that gas in a desorption heating circulation system is led into a catalyzing bed when the concentration of industrial volatilizable organic pollutant in the gas reaches the self-sustaining combustion concentration, the preheated catalyzing bed can rapidly enter the self-sustaining combustion state, feedback heat generated by catalyzing combustion is sufficient to maintain the temperature of the catalyzing bed, a plate heat exchanger obtains sufficient heat sources to provide heat energy for the adsorption bed to continuously carry out desorption, meanwhile, desoprtion preheating is carried out on the next adsorption bed, the design working condition requirement is met, the effect is effectively developed, and conditions are created for less auxiliary heating and energy consumption saving.
Description
Technical field
The invention belongs to the adsorbent bed field, especially a kind of controlled adsorbent bed of concentration of exporting.
Background technology
Maximum no more than industrial volatile organic pollutants to people's health harm in PM2.5, in prior art, industrial volatile organic pollutants is mainly adopted to the catalytic bed firing method, after by adsorbent bed, industrial volatile organic pollutants being carried out to Adsorption Concentration, carry out again desorption and enter the catalytic bed burning, industrial volatile organic pollutants is converted into carbon dioxide and water, the gas temperature after burning is higher carry out thermal energy exchange by plate type heat exchanger after heat energy for the adsorbent bed desorption.When existing adsorbent bed heats from starting desorption, the circulatory system accesses catalytic bed.Because VOCs concentration in initial segment and latter end gas is low, the combustion heat produced can not meet the system operation demand of " controlling oneself ", maintain the heating of catalytic bed temperature and adsorbent bed desorption and can only rely on auxiliary thermal source to be supplemented for a long time, therefore cause the system operation energy consumption very high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of controlled adsorbent bed of concentration of exporting is provided, this adsorbent bed structure is arranged simply, design science is reasonable, output industrial volatile organic pollutants concentration is controlled, for continuing Energy Conservation, has supplied guarantee.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of controlled adsorbent bed of concentration of exporting, comprise an adsorbent bed, on its this adsorbent bed, the desorption gas loop exit is set, this desorption gas loop exit connects the electric heater air inlet by pipeline, this electric heater air outlet connects desorption gas circulating fan air inlet by pipeline, and this desorption gas circulating fan outlet connects the desorption gas loop head on adsorbent bed by pipeline.
And, be provided with industrial volatile organic pollutants exhaust gas inlet and purified gas outlet on described adsorbent bed.
