Description

Technical Field

[0001] The utility model relates to the technical field of synthesis gas washing devices, in particular to a synthesis gas washing device. Background Art

[0002] Synthesis gas is generally produced by gasification of solid fuels such as coal or coke. It is a raw gas with hydrogen and carbon monoxide as the main components. Crude synthesis gas generally contains a large amount of solid particles, and a scrubber is generally required to settle the solid particles. The scrubber is a new type of gas purification and treatment equipment. It is improved on the basis of the floating packing layer gas purifier. It is widely used in pre-treatment of industrial waste gas purification and dust removal, and the purification effect is very good. For the coal gasification process, coal gas scrubbing is inevitable. No matter what coal gasification technology is used, this unit operation is used. Because its working principle is similar to the scrubbing process, it is called a scrubber.

[0003] With the development of society, environmental problems are becoming increasingly serious. In order to solve environmental problems, energy conservation and environmental protection have always been my country's basic national policy. In the existing technology, when the washing tower performs gas purification and separation treatment on solid particles in crude synthesis gas, most of them directly utilize the contact between gas and washing liquid to transfer pollutants and particulate matter in the gas to the liquid, and then separate the clean gas from the contaminated liquid to achieve the purpose of purifying the air. Although this treatment method can cool the exhaust gas, condition the gas and remove particles in the gas, it is found in the actual use process that when there are more solid particles in the crude synthesis gas, when the gas is separated and purified by the washing tower in the existing technology, in order to ensure that the gas purification meets the standards, the washing liquid will be frequently replaced, which not only wastes a lot of washing liquid resources, but also forms industrial wastewater when the washing liquid is saturated. If the wastewater of the washing liquid is not treated properly, it is easy to cause secondary pollution to the environment, and the environmental protection performance is relatively poor.
