Problems solved by technology

However, no matter it is activated carbon or activated carbon fiber adsorption waste gas treatment device, its desorption process is intermittent. Even if it is equipped with a combustion furnace, the operation of the combustion furnace is not stable, so that the combustion is not complete and the pollutants cannot be effectively decomposed.
Another reason is that the amount of desorbed gas is usually very small, and it is uneconomical to build a single combustion device

Embodiment Construction

[0030] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.

[0031] The existing waste gas treatment method discharges to the front end of the adsorption tower for adsorption, resulting in low treatment efficiency of the waste gas device and the phenomenon that the tail gas does not meet the standard; the desorption tail gas is introduced into the sewer or sewage system without degrading pollutants, which expands the scope of odor pollution.

[0032] Such as figure 1 As shown, the desorption and desorption gas treatment device provided by the embodiment of the present invention includes: an air compressor 1, a non-condensable gas storage tank 2, a sewage outlet 3, a feed port 4, a pressure gauge 5, a safety valve 6, and a discharge port 7. Flow meter 8, flame arrester 9.

[0033] The air compressor 1 is connected to t...

Abstract

The invention belongs to the technical field of waste gas pollution control and discloses a desorption desorbed gas processing device and method. The desorption desorbed gas processing method comprises the following steps: pressurizing desorption desorbed gas of waste gas by a compressor; storing the pressurized gas in a noncondensable gas storage tank; adopting a pressure transmitter to control an automatic changeover valve to be opened or closed; and guiding a noncondensable gas into a torch or a boiler nearby for combustion by a pipeline. The desorption desorbed gas processing device comprises a noncondensable gas storage tank, wherein an air compressor is connected with the noncondensable gas storage tank through a pipeline; the noncondensable gas storage tank is connected with a flowmeter through a pipeline; and the flowmeter is connected with a fire arrester through a pipeline. The desorption desorbed gas processing device and method prevent pollutants from accumulation, the pollution range cannot be expanded, and the calorific value of the pollutants in tail gas can be comprehensively utilized by conditional factories, so that energy reutilization is realized.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a desorption and desorption gas treatment device and method. Background technique [0002] At present, the existing technology commonly used in the industry is as follows : Adsorption is a widely used waste gas treatment technology, especially in oil and gas recovery, organic solvent recovery and VOCs waste gas treatment. Common adsorption technologies include activated carbon adsorption, carbon fiber adsorption and zeolite rotor adsorption technology. After the adsorbent is saturated, desorption is required to regenerate the adsorbent, but the adsorption and desorption gas needs to be treated. At present, in addition to the zeolite rotor adsorption technology supporting RTO or RCO equipment for thermal oxidation treatment of the desorbed gas, activated carbon and carbon fiber mostly use circulating water or condensing units to condense the desorbed gas,...
