Embodiment Construction

[0044] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0045] Such as Figure 1-3 As shown, an exhaust gas purification system is characterized in that it includes a heating device 1 , an exhaust gas scrubber 2 , an activated carbon adsorption tower 3 , an induced draft fan 4 and a gas discharge unit 5 . They are connected sequentially by pipes.

[0046] The function of the heating device 1 is to increase the molecular motion of the exhaust gas by heating, which promotes the reaction between the exhaust gas and the absorption treatment liquid, thereby making the filtration and absorption more thorough, and at the same time increasing the upward movement of the air flow and reducing the work load ...

Abstract

The invention relates to an exhaust gas purification system. The exhaust gas purification system is characterized by comprising a heating device, an exhaust gas scrubbing tower, activated carbon adsorption towers, an induced draft fan and a gas discharge part which are connected in turn through pipes. A gas drying device and a gas temperature control device are sequentially arranged on the pipeline between the exhaust gas scrubbing tower and the activated carbon adsorption towers. The activated carbon adsorption towers are also connected with a catalytic combustion device and a desorption fanthrough pipelines, and the activated carbon adsorption towers, the catalytic combustion device and the desorption fan form a closed loop structure through the pipelines. According to the system, the heating device is arranged to promote the reaction between exhaust gas and absorption treatment liquid, and the purification effect is improved. The gas drying device and the gas temperature control device are arranged on the pipeline between the exhaust gas scrubbing tower and the activated carbon adsorption towers, dehumidifying layers are arranged inside the activated carbon adsorption towers, and activated carbon temperature controllers are arranged on activated carbon adsorption layers, so that the exhaust gas and the working environment keep dry, the temperature is controlled in 30-40 DEGC, the effect of activated carbon adsorption of organic components in the exhaust gas is improved, and the effect of exhaust gas purification is improved.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a purification system containing both acidic and organic waste gas. Background technique [0002] The production and testing of the chemical and pharmaceutical industries will produce a large amount of waste gas, and there are two main types of these waste gases. One type is acid waste gas represented by chlorine, hydrogen sulfide, nitrogen dioxide, hydrogen chloride, sulfur dioxide, etc.; the other type is organic waste gas represented by methanol, ethanol, benzene, toluene, xylene, formaldehyde, and organic naphthalene. These gases often have corrosive or irritating odors or carcinogenic properties, so their discharge into the atmosphere will have a great impact on the environment. [0003] At present, there are many studies on the removal of organic waste gas, but there are few purification systems that can simultaneously remove organic waste gas and acid waste gas. In add...
