Abstract

The invention discloses a solid heat carrier pyrolyzer. The solid heat carrier pyrolyzer comprises a top cover (1), a bed body (2) and a slewing mechanism, wherein a ring-shaped pyrolyzing tank is formed in the top surface of the bed body; the top cover seals and covers the pyrolyzing tank from the top; a feed opening (5), pyrolyzing gas outlets (6) and a discharge point, which communicate with the pyrolyzing tank are sequentially arranged at intervals in the circumferential direction of a capping ring region corresponding to the pyrolyzing tank in the top cover, in the capping ring region, a fan ring region on one side between the discharge point and the feeding opening is a pyrolyzing region (D1), and a fan ring region on the other side is a reheating region (D2) connected to a heating device; and along with the rotation of the bed body, solid heat carriers in the pyrolyzing tank are reheated through the heating device, the heated solid heat carriers enter the pyrolyzing region to be mixed with pyrolyzing raw materials, then mixed materials are pyrolyzed, one part of pyrolyzed products as pyrolyzed finished products are discharged through the discharge point, and the other part of the pyrolyzed products are circulated to return the reheating region. The pyrolyzer is novel and compact in structure and small in land occupation space, and integrates the functions of pyrolyzing, discharging, heating of solid heat carriers, circulating and the like.

Description

technical field [0001] The invention belongs to the field of coal chemical industry, and in particular relates to a pyrolyzer. Background technique [0002] In the current low-rank coal pyrolysis process, gas heat carrier or solid heat carrier is usually used as the heating heat source. However, there will be a series of technical problems in the project, such as the large diameter of the pipeline caused by the large amount of heat source gas in the gas heat carrier process, engineering problems such as pipeline preparation, valve selection, and high-temperature equipment selection. The selection of high-temperature explosion-proof equipment in the process of screening of medium-high temperature solid heat carrier, horizontal and vertical transportation of heat carrier, reheating of heat carrier, mixing of heat carrier and coal, etc., system safety and air tightness problems in the whole process , as well as problems such as high failure rate and high energy loss in the who...
