Solid cracking product heat energy solid-liquid exchange discharging device

Abstract

The invention belongs to the technical field of solid waste treatment, and particularly relates to a solid cracking product heat energy solid-liquid exchange discharging device. The device comprises a rotatable outer cylinder and pore plates arranged at the two ends of the outer cylinder in a sleeving mode; the two ends of the outer cylinder are connected with a solid cracking product feeding bin and a solid cracking product discharging bin, respectively; a water inlet pipe is arranged in the center of the pore plate located on one side of the discharging bin; a cavity is formed in the outer cylinder corresponding to the water inlet pipe; material pipes are evenly arranged around the cavity; the two ends of the material pipes are fixedly connected to the pore plates; rotating belts are arranged in the material pipes; and a water return pipe is further sleeved with the water inlet pipe. According to the heat energy solid-liquid exchange discharging device with the structure, solid cracking products enter the feeding bin to achieve material accumulation, the outer cylinder drives the pore plates and the material pipes to rotate, cooling water reversely exchanges heat with the materials after entering the outer cylinder, the cooled solid cracking products are discharged through the discharging bin, and the cooling water is discharged through the water return pipe after being heated, so that heat carried by the solid cracking products is effectively recovered and converted while the solid cracking products are discharged.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a thermal energy solid-liquid exchange discharge device for solid cracking products. Background technique [0002] At present, various solid hazardous wastes such as waste rubber and waste plastics can be processed by pyrolysis. After pyrolysis of these polymer materials, a large amount of recyclable oil and gas can be produced, as well as carbon black, ash, steel wire, etc. Solid pyrolysis products, this part of the product will carry a lot of heat energy when it is discharged from the cracker.

[0002] At present, various solid hazardous wastes such as waste rubber and waste plastics can be processed by pyrolysis. After pyrolysis of these polymer materials, a large amount of recyclable oil and gas can be produced, as well as carbon black, ash, steel wire, etc. Solid pyrolysis products, this part of the product will carry a lot of heat energy when it is discharged from the cracker. The inventor of the present application has previously applied for a corresponding water-cooled discharger and other devices to recover this part of the heat energy, but the previous application The cooling water in the cooling water absorbs the heat through the thermal radiation of the solid cracking product, resulting in low solid-liquid heat exchange efficiency, incomplete heat exchange and the difficulty of obtaining hot water temperature to meet the requirements of industrial applications. Utilization requires additional heating, resulting in an increase in processing costs, and at the same time causing incomplete heat transfer of solid cracked products, which brings difficulties to subsequent processing
