Embodiment 1

[0039] Biomass self-heating carbonization device, see figure 1 The device includes a carbonization sealing device 1 , a decoking and dust removal device 2 , an exhaust gas absorption device 3 and a temperature detection and control device 4 .

[0040] The carbonization sealing device 1 includes a cavity, a bearing column 7 and a rocker-type lifting device 9 . The cavity is a hollow cylindrical container, and the cavity includes a furnace door 5 , an air inlet 6 , a feeding port 8 and an exhaust port 10 . The furnace door 5 is located at the bottom of the cavity. The air inlet 6 is arranged at the bottom of the cavity and one side of the furnace door 5, and the air inlet 6 is used for air intake and temperature measurement. The feeding port 8 is set on one side of the top of the cavity, and the exhaust port 10 is set on the other side of the top of the cavity. The load-bearing column 7 is arranged on the side of the cavity close to the feeding port 8, and the load-bearing co...

Embodiment 2

[0046] A biomass self-heating carbonization device, the device includes a carbonization sealing device 1 , a decoking and dust removal device 2 , an exhaust gas absorption device 3 and a temperature detection and control device 4 .

[0047] The carbonization sealing device 1 includes a cavity, a bearing column 7 and a rocker-type lifting device 9 . The cavity is a hollow cylindrical container built by nesting stainless steel liner and refractory brick outer wall. The inner liner and the outer wall are filled with perlite. The cavity includes a furnace door 5, an air inlet 6, a feeding port 8 and a row Air port 10. The furnace door 5 is located at the bottom of the cavity, and the furnace door 5 and the feeding port 8 are sealed by a high-temperature-resistant insulating door with an asbestos gasket. The high-temperature-resistant insulating door is a fire-resistant door filled with refractory sponge. The air inlet 6 is arranged at the bottom of the cavity and one side of the ...

Embodiment 3

[0053] Based on the device described in embodiment 2, the difference is that, see image 3 , the cavity in the carbonization sealing device 1 also includes a vent tube, the vent tube is attached and fixed on the inner wall of the cavity, one end of the vent tube is connected to the air inlet 6, the other end is arranged on the top of the cavity, and the vent tube body is Open ventilation holes. The ventilation pipe is a spiral ventilation pipe, and the opening of the ventilation hole is inclined to the center of the cavity at an angle of 45 degrees. When the biomass inside the cavity is burned, nitrogen gas is input from the vent pipe, and the nitrogen gas introduced obliquely carries the heat from the bottom to the upper part of the cavity. The bottom heat is transferred to the upper part through the natural rising of nitrogen (usually the bottom combustion temperature is high, the upper temperature is not enough, it is easy to cause excessive smoldering at the bottom, too h...

Abstract

The invention discloses a biomass self-heating carbonization device and application thereof, which belongs to the technical field of biomass carbonization. The device comprises a carbonization sealingdevice, a decoking and dust removal device, a tail gas absorption device and a temperature detection control device, wherein the carbonization sealing device comprises a cavity body, a bearing columnand a rocker arm type lifting device, the cavity body is a hollow cylindrical container, the bearing column is vertical to the upper top surface and the lower top surface of the cavity body, and therocker arm type lifting device is used for lifting materials. And the decoking and dust removing device is a pulse type bag dust remover and is used for decoking and dust removing of gas. The tail gasabsorption device is a tail gas absorption tank and is used for removing sulfur dioxide and nitrogen oxides in the tail gas after decoking and dust removal. The temperature detection control device comprises an asbestos plug, a digital thermometer and a nitrogen bottle, which is used for controlling the temperature in the cavity body. The biochar prepared by the device has uniform quality, can give consideration to the high-quality and high-efficiency production of the product, and the device can spontaneously supply heat, which is environment-friendly, and has high yield of the prepared product.

Description

technical field [0001] The invention belongs to the technical field of biomass carbonization, and in particular relates to a biomass self-heating carbonization device and its application. Background technique [0002] The application of biochar in agricultural production has always attracted much attention. Applying biochar to the soil can have many beneficial effects on the soil. Its role is mainly manifested in: improving the soil's ability to absorb nutrients and cation exchange capacity , Adjust soil pH, improve soil structure and other physical properties, enhance soil water retention capacity, promote the development of soil microbial populations and enhance the activity of soil microorganisms, reduce greenhouse gas emissions, and stabilize soil organic carbon pools. On the one hand, the application of biochar can alleviate the environmental pressure caused by straw burning, and on the other hand, the carbon negative effect of biochar can enhance the carbon "sink" effe...
