[0022] When in use, the water pump 8 pumps the water in the water tank 6 and transports it to the filter tube 4 through the vertical pipe 7. The heating resistance wire in the heating part 9 on the vertical pipe 7 heats the water to improve the water's ability to dissolve and adsorb tar and dust in the gas and reduce its ability to dilute and dissolve combustible gas. When the liquid level sensor 12 in the outlet pipe 1 2 and the outlet pipe 2 5 detects the water flow, the filter tube 4 is filled with water. Afterwards, the combustible gas generated in the furnace body 1 enters the filter tube 4 through the outlet pipe 2 under the action of the vacuum pump 3. The gas passes through the heat The tar and dust are fully contacted with water to clean and dissolve the treated gas, and the treated gas is discharged from the outlet pipe 25. The outlet pipe 25 is connected to the collection device to facilitate the collection of the purified combustible gas. The switch valve 11 is used to control the water flow of the vertical pipe 7 and the return pipe 10. The return pipe 10 returns the used water to the return tank 6 to achieve recycling. The gasification furnace device can efficiently remove the tar and dust carried in the combustible gas, significantly improve the cleanliness of the combustible gas, and create more favorable conditions for the subsequent combustion process.

A symmetrical scraper 20 is arranged on the inner wall of the filter tube 4, and the ends of the stirring rod 19 are respectively fixedly installed with the scraper 20;

[0028] A motor 17 fixedly installed at one end of the filter tube away from the vertical tube 7 drives a rotating rod 18 to rotate in the filter tube 4, and stirring rods 19 evenly distributed and symmetrical on the rotating rod 18 rotate accordingly, so that the water entering the filter tube 4 is fully mixed with the tar and dust, thereby improving the cleaning and dissolution efficiency. At the same time, a symmetrical scraper 20 arranged on the inner wall of the filter tube 4 is fixedly installed on the end of the stirring rod 19, and the rubber strip on the scraper 20 fits against the inner wall of the filter tube 4. As the stirring rod 19 rotates, the scraper 20 continuously scrapes off the tar and dust attached to the inner wall of the filter tube 4 to prevent blockage, thereby ensuring the continuous and efficient operation of the filter tube 4.

[0029] A rubber strip is laid on one side of the scraper 20 close to the inner wall of the filter tube 4. The rubber strip is made of rubber and fits the inner wall of the filter tube 4.

Once an abnormality is found or maintenance is required, an alarm is promptly issued and corresponding measures are taken to ensure the stable operation of the system and the efficient removal of tar and dust in the combustible gas.

[0033] Working principle:

[0034] When in use, the water pump 8 pumps out the water in the water tank 6 and transports it to the filter tube 4 through the vertical pipe 7. The heating resistance wire in the heating part 9 on the vertical pipe 7 heats the water to improve the water's ability to dissolve and adsorb tar and dust in the gas and reduce its ability to dilute and dissolve combustible gas. When the liquid level sensor 12 in the outlet pipe 1 2 and the outlet pipe 2 5 detects the water flow, the filter tube 4 is filled with water. After that, the combustible gas generated in the furnace body 1 enters the filter tube 4 through the outlet pipe 1 2 under the action of the vacuum pump 3. The gas is fully in contact with the hot water to clean and dissolve the tar and dust. The treated gas is discharged from the outlet pipe 2 5. The outlet pipe 2 5 is connected to the collection device to facilitate the collection of the purified combustible gas. The switch valve 11 is used to control the water flow of the vertical pipe 7 and the return pipe 10. The return pipe 10 returns the used water to the return tank 6 to achieve recycling.

[0035] A filter plate 14 is installed in the filter part 13 arranged on the return pipe 10. When the used water returns to the water tank 6 through the return pipe 10, the filter plate 14 can effectively intercept the tiny tar particles and dust that may be carried in the water, preventing them from re-entering the water tank 6 and affecting the subsequent water quality and filtering effect, further improving the filtering efficiency of the system and the cleanliness of the combustible gas; the plug block 15 on one side of the filter plate 14 is slidably arranged on the filter part 13, which is convenient for the installation and removal of the filter plate 14. The sealing rubber plate on the plug block 15 ensures the close fit between the filter plate 14 and the filter part 13 to prevent water leakage. The cross bar 16 on the side of the plug block 15 away from the filter plate 14 is convenient for operators to replace and maintain the filter plate 14, ensuring the continuous and efficient operation of the system;

[0036] The motor 17 fixedly installed at one end of the filter tube away from the vertical tube 7 drives the rotating rod 18 to rotate in the filter tube 4, and the stirring rods 19 evenly distributed and symmetrical on the rotating rod 18 rotate accordingly, so that the water entering the filter tube 4 is fully mixed with the tar and dust, thereby improving the cleaning and dissolution efficiency. At the same time, the symmetrical scraper 20 arranged on the inner wall of the filter tube 4 is fixedly installed at the end of the stirring rod 19, and the rubber strip on the scraper 20 fits with the inner wall of the filter tube 4. With the rotation of the stirring rod 19, the scraper 20 continuously scrapes off the tar and dust attached to the inner wall of the filter tube 4 to prevent clogging, thereby ensuring the continuous and efficient operation of the filter tube 4; the rubber strip laid on one side of the scraper 20 close to the inner wall of the filter tube 4 is made of rubber material, which has good elasticity and wear resistance. The rubber strip fits tightly with the inner wall of the filter tube 4, ensuring that the scraper 20 can effectively scrape off the tar and dust on the inner wall when rotating, while reducing the friction and wear between the scraper 20 and the inner wall of the filter tube 4, thereby extending the service life of the equipment;

[0037] The controller provided on the water tank 6 is electrically connected to the furnace body 1, the vacuum pump 3 and the switch valve 11 respectively, realizing intelligent control of the whole system. The controller can automatically adjust the working state and water flow rate of the water pump 8 according to the signal of the liquid level sensor 12, ensuring that the filter tube 4 always maintains a suitable water level. At the same time, the controller can also monitor the operating state of the furnace body 1 and the working condition of the vacuum pump 3. Once an abnormality is found or maintenance is required, an alarm is issued in time and corresponding measures are taken, thereby ensuring the stable operation of the system and the efficient removal of tar and dust in the combustible gas;
