An externally heated low temperature carbonization converter

Abstract

The invention discloses an external heat type low-temperature carbonization converter which comprises a furnace body, a rolling device and a transmission mechanism which are arranged outside the furnace body, wherein the furnace body comprises a furnace wall, a feeding mechanism and a discharging mechanism, wherein the furnace wall is formed by an outer housing layer, an insulating layer and an inner housing layer which are sequentially connected, the feeding mechanism is arranged at one end of the furnace wall, the discharging mechanism is arranged at the other end of the furnace wall, the feeding mechanism comprises a feeding pipe, a feeding plate for fixing the feeding pipe, a feeding cover arranged under the feeding plate and fixed on the furnace body, a feeding lifting plate fixed on the inner side wall of the feeding cover, and a feeding pipe plate arranged below the feeding cover and fixed on the furnace body, a gas outlet pipe is fixed in the middle of the feeding pipe plate; the discharging mechanism comprises a discharging pipe plate arranged on the furnace body, an insulating material, a heat insulation pipe plate and a discharging cover; one end of the gas inlet pipe is fixed in the middle of the discharging pipe plate, and the other end of the gas inlet pipe is connected with a gas inlet pipe joint. The external heat type low-temperature carbonization converter disclosed by the invention is high in integral reliability, and is safe and environment-friendly; produced materials are stable in quality, and continuous industrialized production can be performed.

Description

technical field [0001] The invention relates to an externally heated low-temperature carbonization converter, which is mainly used for the production of coal, wood, asphalt, resin, etc., isolated from air and heated to a final temperature of 300-600°C to pyrolyze it to obtain carbonized materials or pyrolysis products. Background technique [0002] Low-temperature carbonization is one of the important processes in the production of activated carbon. This process is to heat the raw materials to reduce non-carbon elements to produce carbonaceous materials suitable for the activation process. It is the main process before activation. Due to the many advantages of the externally heated low-temperature carbonization converter, it has become the development trend and direction, especially the multi-chamber externally heated low-temperature carbonization converter has more advantages, but this type of externally heated low-temperature carbonization converter has material The proble...

Problems solved by technology

Due to the many advantages of the externally heated low-temperature carbonization converter, it has become the development trend and direction, especially the multi-chamber externally heated low-temperature carbonization converter has more advantages, but this type of externally heated low-temperature carbonization converter has material The problem of the expansion and sealing of the channel makes the equipment unable to produce normally for a long time

[0003] Known public technology The Chinese invention patent specification disclosed "an external heating low-temperature carbonization converter" (patent number: ZL201320592697.7) on September 16, 2013. The structure of the carbonization furnace has solved the problem that the material channel is slid in the furnace The support tube plate is well supported without breaking the material channel, but the material channel seal is set at the discharge tube plate, where the temperature is the high temperature section of the equipment during normal production, most of the sealing packing, fiber cloth etc. cannot bear the oxidation resistance at high temperature, so that the expansion seal at the discharge tube plate cannot be used for a long time, which brings a lot of troubles to industrialized continuous production, and its reliability is reduced, product quality stability is affected, and it is also Unable to do a good job of safety and environmental protection
