A biomass pyrolysis horizontal converter with a load-bearing sealing structure

Abstract

The object of the present invention is to provide a biomass pyrolysis horizontal converter with a load-bearing and sealed structure. The horizontal converter pyrolysis and drying are completed in the same furnace. The internal parts of the converter cylinder are simple, and the horizontal converter and static parts The sealing performance between them is good, and there is no need to set additional load-bearing parts for the horizontal converter shell, which simplifies the workload for installation, maintenance, and replacement, including the converter shell, the front head set at the front end of the converter shell, and the The rear head of the rear end of the cylinder body, the two ends of the cylinder body respectively extend into the front head and the rear head, and are connected to the front head and the rear head in a relatively rotatable sealing connection, and the inside of the cylinder body is set There is a pyrolysis pipe for heating gas circulation, and the bottom of the front head is connected to the exhaust pipe for exhausting exhaust; the bottom of the rear head is provided with a burner, and the rear head is also equipped with a blower. The air blower mentioned above is used to blow the heat energy burned by the burner into the pyrolysis tube.

Description

technical field [0001] The invention belongs to the technical field of biomass pyrolysis, and in particular relates to a biomass pyrolysis horizontal converter with a load-bearing sealing structure. Background technique [0002] Biomass pyrolysis is to convert biomass into combustible gas and natural resources. It has the advantages of high energy conversion rate, easy access to raw materials, easy transportation, and easy industrial utilization. At present, biomass pyrolysis technology has also gained more and more attention. There are many researches and developments. The existing biomass pyrolysis furnaces are mainly vertical and horizontal. Among them, the horizontal converter has gradually expanded its application range due to the characteristics of slow material movement, sufficient pyrolysis, and convenient control of products. However, the current A horizontal converter is often equipped with a lot of rotating parts in the furnace body and needs to be equipped with a...

[0002] Biomass pyrolysis is to convert biomass into combustible gas and natural resources. It has the advantages of high energy conversion rate, easy access to raw materials, easy transportation, and easy industrial utilization. At present, biomass pyrolysis technology has also gained more and more attention. There are many researches and developments. The existing biomass pyrolysis furnaces are mainly vertical and horizontal. Among them, the horizontal converter has gradually expanded its application range due to the characteristics of slow material movement, sufficient pyrolysis, and convenient product control. However, the current A horizontal converter is often equipped with a lot of rotating parts in the furnace body and needs to be equipped with a drying furnace, and because the whole cylinder is constantly rotating, the gap between the cylinder and the gas extraction parts or the head parts at both ends of the cylinder The sealing between them has become one of the difficult problems. For example, the patent document CN201014917Y discloses a fully sealed atmosphere-protected high-temperature continuous calcination rotary furnace, and the patent document CN201242334Y discloses a connecting part between the drum dryer and the hot blast stove, which essentially solves the Both are sealing issues between the rotating cylinder and the end connecting parts, and both of them use two seals in face-to-face contact, and use spring force to press the two seals together to achieve sealing
