Problems solved by technology
Due to the limited solubility of acid gas, it is released into the exhaust gas system in the condensate tank. If the overall exhaust gas system in the factory area is not working properly and the gas escapes, or when local maintenance is shut down, a small or trace amount of toxic acid Gas may threaten the safety and health of nearby workers

Embodiment Construction
[0018] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0019] See Figure 1-Figure 2 , is a schematic structural view of the gas-liquid separation device of the present invention, a gas-liquid separation process for preventing condensate from entraining acid gas according to the present invention, the condensate and acid gas after vacuum carbonate desulfurization of coke oven gas are acidified from the top The steam inlet 2 enters the gas-liquid separator 1, and the acid gas flows through the airflow baffle 4 to change the flow direction, and after passing through the perforated baffle 5, it is discharged from the acid gas outlet 3 on the other side of the top of the gas-liquid separator 1; Enter the gas-liquid separator 1 at a flow rate of 1-2m / s and flow to the side of the bottom condensate outlet 7; through the liquid level controller 12, the condensate in the gas-liquid separator 1 is automaticall...

The invention relates to a gas-liquid separation technology and device preventing a condensate liquid from carrying acid gases. A condensate liquid of coke oven gas vacuum carbonate after desulphurization and acid gases go into a gas-liquid separator from an acid gas inlet at the top, the flow direction of the acid gases is changed through an air flow baffle plate, and then the acid gases are subjected to flow equalization through a baffle plate with holes and are discharged from an acid gas outlet at the other side of the top of the gas-liquid separator. The condensate liquid goes into the gas-liquid separator at a flow speed of 5-6m / s and flows towards a condensate liquid outlet at the bottom. The condensate liquid in the gas-liquid separator is controlled to keep at a liquid level of more than 100m automatically through a liquid level controller. The condensate liquid of coke oven gas vacuum carbonate after desulphurization and acid gases can be separated fully, and acid gases are prevented from going to a condensate liquid tank for aggregation in a micro-bubble form along with the condensate liquid and further escaping from the condensate liquid tank to cause leakage of toxic gases. Health and safety of operating personnel are ensured, and the environment is protected.
Description
technical field [0001] The invention relates to the technical field of safety protection and environmental protection in the coking industry, in particular to a gas-liquid separation process and device for preventing condensate from entraining acid gas matched with the coke oven gas vacuum carbonate desulfurization process. Background technique [0002] In the gas purification device of coking enterprises, when using the vacuum carbonate desulfurization process, it is usually necessary to set up a gas-liquid separation device. The function of this device is to condense and cool the acid gas and condensate from the desorption tower Effective separation is carried out, and the separated acid gas goes to the vacuum pump or subsequent equipment, and the condensate is discharged into the condensate tank by gravity flow through the potential difference. [0003] Through return visits to a large number of coking enterprises using the above process, relevant technical personnel have...
