The invention discloses a waste gas treatment device. The waste gas treatment device comprises a coal synthesis gas sulfur recovery tail gas incineration device, a polyethylene degassing device, a polypropylene degassing device and a heating device, wherein a first waste gas outlet is formed in the coal synthesis gas sulfur recovery tail gas incineration device; a second waste gas outlet is formed in the polyethylene degassing device; a third waste gas outlet is formed in the polypropylene degassing device; a fuel gas inlet is formed in the heating device; and the fuel gas inlet is connected with the first waste gas outlet, the second waste gas outlet and the third waste gas outlet. Through adoption of the waste gas treatment device provided by the invention, on one hand, all waste gases are subjected to innocent treatment through the self-contained heating device in a coal-to-olefin factory, and cost is relatively low; and on the other hand, energy in the waste gases is recycled as heat, and energy utilization efficiency is further improved.
Description
technical field [0001] The invention relates to the field of coal chemical industry, in particular to a waste gas treatment device. Background technique [0002] Coal-to-olefins technology has made significant progress in recent years due to breakthroughs in methanol-to-olefins technology. Several sets of equipment are under construction or have been put into industrial commercial operation, and have obtained very good economic benefits. Coal-to-olefins technology uses coal as the raw material, which is gasified to obtain crude gas whose effective components are carbon monoxide and hydrogen. After conversion and adjustment of the carbon-hydrogen ratio, the crude gas becomes synthesis gas after purification and removal of acid gas. The synthesis gas is produced in methanol synthesis catalyst Methanol is produced under the action, and methanol is then passed through a methanol-to-olefin unit (MTO) to produce olefins, and olefins are usually produced in a polymerization unit to...
