Abstract
The utility model relates to an energy-saving type adsorption bed capable of controlling the output concentration. The energy-saving type adsorption bed comprises an adsorption bed body, wherein a desorption gas circulating outlet is formed in the adsorption bed body and is connected with an air inlet of an electric heater through a pipeline; an air outlet of the electric heater is connected with an air inlet of a desorption gas circulating fan through a pipeline; an outlet of the desorption gas circulating fan is connected with a desorption gas circulating inlet in the adsorption bed through a pipeline; a plate type heat exchanger is connected to the pipeline between the electric heater and the desorption gas circulating fan. Due to the structure, the technical assumption that gas in a desorption heating circulating system cannot be introduced into a catalysis bed until the concentration of industrial volatilizable organic pollutants in the gas reaches the self sustaining combustion concentration is realized, so that the preheated catalysis bed can quickly enter a self sustaining combustion state, and the heat feedback generated by catalysis combustion is enough to support the temperature needed by the catalysis bed; furthermore, the plate type heat exchanger can obtain enough heat to meet a requirement on a design working condition and effectively achieve the effect. Conditions are created for auxiliary heating and energy consumption reduction.
