Deslagging mechanism special for acetylene recovery in dry acetylene carbide slag

Abstract

The invention discloses a deslagging mechanism special for acetylene recovery in dry acetylene carbide slag, which comprises an air inlet chamber, a spray chamber, an exhaust chamber, a motor bin, a slurry stirring tank, a filter pressing cylinder and a slurry separation tank, a filter screen is arranged at the communication part of the exhaust chamber and the spray chamber, the filter screen is wound by two dull polish rollers, and the dull polish rollers are connected with a rotating shaft in a penetrating manner; an arc-shaped plate covers the top of the filter screen, and a semi-cylindrical groove is formed in the bottom of the filter screen; an overturning plate, a spring and a strip-shaped through hole are arranged on the connecting wall of the spraying chamber and the air inlet chamber; the water spraying pipe faces the surface of the overturning plate; the slurry separation tank is provided with a filter block, a spraying water pump and a slurry pump; the overflow pipe extendsinto the slurry stirring tank; and the filter pressing cylinder is provided with a filter pressing plate, a discharge pipe joint and an air compressor. According to the invention, a slurry mixture isprepared by adopting a wet circulation process, then a double-layer filter cloth structure is constructed, and slurry is adhered to the filter screen to form a uniform filter water film structure, sothat dust particles in carbide slag can be fully absorbed, slurry circulation is realized, and the water consumption is low.

Description

technical field [0001] The invention relates to the technical field of carbide slag recovery and utilization, in particular to a slag discharge mechanism specially used for recovery of acetylene from dry-process acetylene carbide slag. Background technique [0002] Compared with the traditional "wet" acetylene preparation process, the dry acetylene process uses a little more than the theoretical amount of water to spray on the calcium carbide powder to hydrolyze it, and the produced calcium carbide slag has a very low water content. dry powder process. [0003] Theoretically, the calcium carbide hydrolysis rate of dry acetylene can reach more than 99%, but in the actual production process, the calcium carbide hydrolysis rate is far from the theoretical value, and there is a problem of excessive consumption of calcium carbide, and the content of raw calcium carbide in the carbide slag is still high. Higher, acetylene recovery treatment is required to reduce the acetylene gas...
