Embodiment 1

[0014] The high-temperature reaction kettle of this embodiment is a special equipment for roasting straw and extracting combustible gas from straw. It is mainly composed of conveying screw, primary heating jacket, secondary heating jacket, ash hopper, spiral stirring and other mechanisms. The specific structure is as figure 1 As shown, there is a tubular conveying channel 1 with an inlet IN and an outlet OUT, a feeding port 2 is provided above the inlet end of the conveying channel, and a screw conveyor 3 outer section 3 is installed in the conveying channel 1 under the feeding port 2 -1, the outer tube 4-1 forming the ring-shaped clamping chamber 4 is wrapped around the outer tube 4-1 corresponding to the inner section 3-2 of the screw conveyor 3, which constitutes the preheating section of the primary heating jacket. The lower part of the outer pipe 4-1 has a waste heat gas inlet 4-2, and the upper part has a waste heat gas outlet 4-3. The hot waste gas inlet 4-2 is adjacen...

Abstract

The invention relates to a high-temperature reaction kettle, belonging to the technical field of combustion reactors. The reaction kettle comprises a tubular conveying channel provided with an inlet end and an outlet end, wherein a feed opening is arranged above the inlet end of the conveying channel; a screw conveyor outer section is arranged in the conveying channel below the feed opening; an outer tube forming an annular clamping bin is arranged on the periphery of a screw conveyor inner section, which corresponds to the conveying channel; a waste heat air inlet is arranged at the lower part of the outer tube; a waste heat air outlet is arranged at the upper part of the outer tube; an arc casing is enclosed at the lower part of the conveying pipeline between an outlet of the screw conveyor and the outlet end to form a heat air channel with a crescent section; a heat air inlet is arranged at one end of the heat air channel, which is close to the inlet end; a heat air outlet is arranged at one end of the heat air channel, which is close to the outlet end; a cellular through hole is arranged between the heat air channel and the conveying channel; and a synthetic gas outlet is arranged above the outlet end of the conveying channel. By setting a second-stage heating structure, the heat of waste gas can be effectively utilized; and proved by practice, biomass extruded and preheated by a conveyor is easier to carbonize and has higher gas yield.

Description

technical field [0001] The invention relates to a reaction kettle, in particular to a high-temperature reaction kettle used for roasting straw and other biomass, and belongs to the technical field of combustion reaction appliances. Background technique [0002] The high temperature reactor is a special equipment for biomass roasting. The typical structure of this type of device is as disclosed in the Chinese patent application whose application number is 200520088755.8 and which is entitled "A Reactor for Making Straw Pulp". The body, the motor fixed on the upper side of the kettle body, the shaft connected to the upper end of the kettle body and the transmission device, the high-concentration hydraulic pulper rotor fixed on the shaft, and the bottom of the kettle body near the bottom of the kettle body, and one end of the vapor-liquid supply pipe. In the kettle body, the underside of the rotor of the high-concentration hydraulic pulper, and the other end protrude from the ...
