Example Embodiment

[0076] Example 1

[0077] Coal samples with a particle size of 5 mm to 30 mm (see Table 1 for coal quality analysis data) are continuously fed into the rotating bed pyrolysis furnace at 3t / h, and directly contact with the non-condensable gas at a temperature of about 580℃ to exchange heat and generate heat Decomposition, heating the coal to 530°C to generate hot semi-coke, tar steam and coal gas. The obtained hot semi-coke temperature is about 500°C and enters the cooling system for cooling and recovery of heat. The cooled semi-coke is sent to the storage bin. The generated oil and gas and the heating non-condensable gas have a temperature of about 520℃. The rotating bed pyrolysis furnace is led out through multiple oil and gas outlets on the top of the rotating bed pyrolysis furnace. The oil and gas outlet positions are different, and the temperature of the outlet oil and gas is different. The oil and gas at each oil and gas outlet merges through the oil and gas main pipe and th...

[0082] Example 2

[0083] The raw material coal used in this example with a particle size of 5 mm to 30 mm is continuously fed into the rotating bed pyrolysis furnace at 2.6t / h, and directly contacts the non-condensable gas at a temperature of about 650℃ to exchange heat and generate heat. Decompose and heat the coal to 600°C to generate hot semi-coke, tar steam and coal gas. The obtained hot semi-coke has a temperature of about 580°C and enters the cooling system for cooling and heat recovery. The cooled semi-coke is sent to the storage bin. The generated oil and gas mixed with heating non-condensable gas have a temperature of about 590°C. The rotating bed pyrolysis furnace is led out through multiple oil and gas outlets on the top of the rotating bed pyrolysis furnace. The oil and gas outlet positions are different, and the outlet oil and gas temperature has certain differences. The oil and gas at each oil and gas outlet merges through the oil and gas main pipe and then enters ...

[0086] Example 3

[0087] Autumn domestic garbage with a particle size of 5 mm to 120 mm is continuously fed into the rotating bed at 1.3t / h, and directly contacts the non-condensable gas at a temperature of about 800℃ to exchange heat and pyrolyze at 700℃ to produce hot solids. Carbon-containing material, tar steam and combustible gas, the obtained hot solid carbon-containing material has a temperature of about 680°C, enters the cooling system for cooling and heat recovery, and the cooled solid carbon-containing material is sent to the storage bin. The produced oil and gas and heating non-condensable gas mixture are led out of the rotating bed through the multiple oil and gas outlets on the top of the rotating bed. The temperature of the produced high-temperature oil and gas mixed with non-condensable gas is 690℃, and the oil and gas outlets of each oil and gas are merged into cooling through the oil and gas main pipe. And in the purification system.

Abstract

The invention provides a pyrolyzing system and a pyrolyzing method. The pyrolyzing system comprises a rotary-bed pyrolyzing furnace, a pyrolyzing solid treatment device, a cooling and purifying device, an oil storage tank and a regenerative rotary heat exchanger, wherein the rotary-bed pyrolyzing furnace is used for pyrolyzing a pyrolyzing raw material; a rotary material dispensing plate for placing the pyrolyzing raw material is arranged inside the rotary-bed pyrolyzing furnace; the material dispensing plate divides the interior of the rotary-bed pyrolyzing furnace into a pyrolyzing chamber above the material dispensing plate and a heating chamber below the material dispensing plate; a plurality of through holes which are communicated with the pyrolyzing chamber and the heating chamber are formed in the material dispensing plate; the heating chamber is provided with a heat inlet; the pyrolyzing chamber is provided with a feed port, a gas outlet and a solid outlet; the regenerative rotary heat exchanger is connected with the cooling and purifying device and the heat inlet of the rotary-bed pyrolyzing furnace respectively, and is used for heating incondensable gas and pyrolyzing the incondensable gas. Due to adoption of the pyrolyzing system provided by the embodiment of the invention, the pyrolyzing efficiency and the pyrolyzing degree of the pyrolyzing material can be significantly improved.

Description

technical field [0001] The invention relates to the field of pyrolysis, in particular, the invention relates to a pyrolysis system and a pyrolysis method. Background technique [0002] Pyrolysis technology is to heat organic matter to 500-1000°C in the absence of oxygen or oxygen, so that solid carbonaceous matter (coal, biomass, garbage, waste tires, waste organic matter, organic sludge, etc.) Gas (pyrolysis gas), fuel oil and pyrolysis carbon are the main storage energy sources. In the gas heating pyrolysis technology, high-temperature flue gas is often used as a heating carrier to directly enter the pyrolysis furnace and pass through the material layer to realize heat transfer. There are few technologies for the product pyrolysis gas to be reused in the pyrolysis process as a gas heating carrier mentioned. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an...
