The invention discloses solid particle cooling equipment for graded and quality-divided utilization of coal. The equipment comprises a shell as well as an upper seal head and a lower seal head which are fixedly arranged at the upper end and the lower end of the shell respectively, the upper seal head is provided with a solid particle inlet, a cooling medium outlet pipe is further connected above the side wall of the shell, the cooling medium outlet pipe extends into the shell and is connected with a cooling medium collector, a cooling medium inlet pipe is further connected below the side wall of the shell, the cooling medium inlet pipe extends into the shell and is connected with a cooling medium distributor, a plurality of round holes are evenly formed in the lower surface of the cooling medium collector and the upper surface of the cooling medium distributor in a one-to-one correspondence mode, corresponding round holes in the lower surface of the cooling medium collector and the upper surface of the cooling medium distributor are jointly connected with a spiral heat exchange pipe, and the lower sealing head is provided with a solid particle outlet. The problems that in the prior art, cooling equipment is low in heat transfer efficiency, small in treatment capacity and prone to blockage, and the temperature is not uniform due to the poor cooling effect of solid particles away from the heat transfer face are solved.
Description
technical field [0001] The invention belongs to the technical field of solid particle cooling devices, and relates to solid particle cooling equipment for coal classification and quality separation. Background technique [0002] At present, in the field of coal classification and high-efficiency utilization, the cooling equipment for solid particles (powder) such as pulverized coal, coke powder and coke powder is mainly a plate heat exchanger, but the heat transfer efficiency of the heat exchanger is low during operation. The problem of small processing capacity and easy clogging, and the unavoidable problem of uneven temperature caused by poor cooling effect of solid particles far away from the heat transfer surface have become technologies that affect and restrict the development of coal classification, quality and efficient utilization industries Therefore, it is of great value and significance to develop new solid particle cooling equipment with high heat transfer effici...
