The heat supply interlayer 5 is communicated with a hot air inlet 6 and a hot air outlet 7. A part of the fuel gas at the fuel gas outlet 9 can provide the required fuel gas for the hot air inlet 6; the temperature in the furnace body is determined by the hot air quantity of the hot air inlet 6 and the temperature controller 10 in the gasification furnace body.
Working example
When the device of the first embodiment works, the catalyst (generally, a nickel-based catalyst and the like) is placed on the semi-in-situ catalyst placing net 3 through the catalyst replacing port 11; hot air combusted by combustible gas enters a heat supply interlayer 5 of the gasification furnace body 1 through a hot air inlet 6, carbon dioxide with set flow enters the gasification furnace body 1 through a carbon dioxide inlet 8, and after a temperature controller 10 is kept constant at a set temperature, the hot air supply quantity of the hot air inlet 6 and the air outlet quantity of a hot air outlet 7 are kept constant, so that the temperature in the gasification furnace body 1 is kept stable; organic solid waste enters a gasification furnace body 1 through a feeder 2 and falls to a movable grate 4, gas generated by cracking the organic solid waste in a gasification cracking space A reacts in a carbon dioxide atmosphere, volatile components generated by the reaction are placed in a net through a semi-in-situ catalyst and participate in catalytic reaction, secondary cracking is performed in a catalytic gasification cracking space B, and finally obtained combustible gas flows out from a combustible gas outlet 9; a small amount of ash slag of gasification reaction enters an ash slag bin 13 through the movable grate 4, and is discharged from a slag outlet 12 after a certain amount of accumulated ash slag is accumulated.
Example three application examples
The application was carried out using the apparatus of example one and the working method of example two, wherein the organic solid waste was plastic low density polyethylene (LDPE, having a lower calorific value of 40.6 MJ/kg), the reaction temperature was determined to be 910 ℃, and a certain amount of carbon dioxide was continuously fed. 1kg of Ni/Al as a nickel-based catalyst was added by using the apparatus of example one2O3The reaction was carried out for 50 minutes by placing it on a semi-in-situ catalyst placement net and then 2kg of LDPE, and all the gases generated were collected and analyzed.
Comparative example
For comparison, a comparative example was set up. The method is characterized in that the organic solid waste is plastic low-density polyethylene (LDPE with a low calorific value of 40.6 MJ/kg), the reaction temperature is 910 ℃, certain carbon dioxide is continuously introduced, the temperature, the introduced carbon dioxide, raw materials, catalysts, the reaction time and the like are the same as those in the embodiment, except that 1kg of the catalysts and 2kg of the LDPE are mixed together and placed on a movable grate (namely, compared with the device in the embodiment I of the invention, semi-in-situ catalyst net placement is not adopted to separate the catalysts and the LDPE, namely, in-situ catalysis), the reaction is carried out for 50 minutes, and all generated gases are collected and analyzed.
The main characteristics of the gases generated in the above application examples and comparative examples are shown in Table 1:

(unit: ratio of gas generation to 1 unit weight)

The semi-in-situ catalysis of the invention is slightly reduced compared with the comparative in-situ catalysis for the generation amount of carbon monoxide and the consumption amount of carbon dioxide, because the plastic is heated and cracked to be adhered to the catalyst in the in-situ catalysis process of the comparative example to form more coke, and the coke reacts with the carbon dioxide to generate more carbon monoxide. However, the catalyst of the comparative example was more easily covered and the carbon deposition phenomenon occurred, as shown in fig. 2. As can be seen, the carbon deposition phenomenon of the catalyst after the in-situ catalytic reaction of the comparative example is heavier, and the catalyst after the semi-in-situ catalysis of the invention hardly deposits carbon; the apparatus and method of the present invention are advantageous in that the catalyst is not easily replaced in the in-situ catalytic process of the comparative example, thereby increasing the operation cost.
