Discharging method for high-temperature carbonized material

Abstract

The invention relates to an animal carbonization treatment method, and in particular, relates to a discharging method for a high-temperature carbonized material. The method includes the following steps: gas replacement: after a carbonization process is finished, immediately introducing non-flammable inert gas into a carbonization tank, and adopting the non-flammable inert gas to replace flammable pyrolysis gas in the carbonization tank; and temperature control and furnace opening: after the temperature in the carbonization furnace is dropped to 500 DEG C or less, opening the carbonization furnace, and making the high-temperature carbonized material in the carbonization tank discharged. The method can avoid low production efficiency caused by a lot of time requiring to be used in a cooling stage and energy loss generated during furnace body cooling, effectively solves the generation of dangerous problems of burning, exploding sounding and the like when a carbonization furnace door is opened at high temperature, successfully implements discharging of the carbonized material in a high temperature state, and solves the problems impossible to be achieved in industry; and at the same time, with combination of flue gas purification treatment, up-to-standard discharging of dioxin in tail gas is achieved.

Description

technical field [0001] The invention relates to an animal carbonization treatment method, in particular to a furnace-extraction method of high-temperature carbonized products. Background technique [0002] After the pyrolysis and carbonization process of organic matter is completed, what remains is solid carbonized matter. Since the carbonization process needs to be completed in an oxygen-free container, the temperature in the furnace is still relatively high after the carbonization is completed, so there is still a certain amount of flammable material in the container. sexual gas. If the furnace door is opened in this state, this part of the flammable gas will burn rapidly after contacting the air, and the volume will expand rapidly, which is very dangerous. Therefore, in the conventional carbonization treatment, it is necessary to wait until the temperature in the furnace drops to room temperature before opening the furnace door to remove the carbides. However, the cooli...

Problems solved by technology

However, the cooling stage takes a lot of time, resulting in low production efficiency and energy loss when the furnace cools down.

[0003] JP2007204563 (2007-08-16) discloses a carbonization treatment device and a carbonization treatment method. This method uses the heat contained in superheated steam to complete pyrolysis or carbonization. The blood and water that will be produced in the waste water, etc., there are difficulties in subsequent wastewater treatment and the risk of pathogenic bacteria infection, and the yield of charcoal is low

At the same time, the patent does not disclose how to release the carbonized animal corpses from the furnace at high temperature. The method used is to wait until the temperature in the furnace drops to room temperature before opening the furnace door to remove the carbides.
