Problems solved by technology

However, if the incineration system is overhauled or fails, the emergency exhaust gas generated by the leachate treatment process and the garbage storage pit cannot be purified through the incineration unit, and an emergency purification system needs to be installed separately
The emergency purification system usually adopts washing method, activated carbon adsorption or a combination of the two, but the washing method is usually not efficient, and it is difficult to effectively purify the emergency exhaust gas, while the activated carbon adsorption method is very easy to reach saturation, and replacement is also troublesome. The combined process of washing method and activated carbon adsorption is also difficult to effectively solve the emergency exhaust problem due to the influence of water vapor and the limitation of adsorption capacity.

Embodiment

[0015] figure 1 It is a system schematic diagram of the emergency exhaust gas treatment system in the embodiment of the present invention.

[0016] like figure 1 As shown, this embodiment provides an emergency exhaust gas treatment system 100 for treating emergency exhaust gas, including: an adsorption module 10 , a desorption module 20 and an exhaust cylinder 30 .

[0017] The adsorption module 10 is used to adsorb the emergency exhaust gas, including: an adsorption box and a hydrophobic adsorption material.

[0018] In this embodiment, the size of the adsorption box is adjusted according to the amount of emergency exhaust gas.

[0019] In this embodiment, the hydrophobic adsorption material is filled inside the adsorption box to absorb the emergency exhaust gas, so that the emergency exhaust gas after adsorption reaches the emission standard, and the wind speed of the hydrophobic adsorption material is 0.2-0.6m / s , The residence time of the hydrophobic adsorption material...

Abstract

The invention provides an emergency emission waste gas treatment system, which is used for treating emergency emission waste gas, and comprises an adsorption module used for adsorbing the emergency emission waste gas; a desorption module used for desorbing the saturated adsorption module after adsorption; and an exhaust funnel connected with the adsorption module and the desorption module and used for exhausting desorbed waste gas. The adsorption module comprises an adsorption box body and a hydrophobic adsorption material; and the desorption module comprises a hot nitrogen box body, a first vacuum pump, a buffer tank, a DBD reactor and a second vacuum pump. The system has a remarkable effect on emergency exhaust gas emission, and can improve and reduce the production cost and the operation cost and ensure the operation safety of equipment under the condition of effective exhaust gas removal efficiency.

Description

technical field [0001] The invention relates to a waste gas treatment system, in particular to a treatment system for emergency discharge of waste gas. Background technique [0002] At present, the proportion of the incineration method in the domestic waste disposal path is increasing year by year, but there are many waste gas pollution problems in the waste incineration process, such as the waste gas from the leachate treatment process, the stench of the waste storage pit, and the incineration flue gas. During normal operation, the waste gas generated by the leachate treatment process and the waste storage pit is generally sent to the incineration system, which is pyrolyzed and purified as primary air and secondary air, and finally enters the flue gas purification system. However, if the incineration system is overhauled or fails, the emergency exhaust gas generated during the leachate treatment process and the garbage storage pit cannot be purified through the incineration...
