[0024] like Figures 1 to 6 As shown, the utility model is a coal gasification hydrogen production and purification device, comprising: a coal-fired furnace 1, a filtering mechanism for filtering coal gas;

[0025] The filtering mechanism comprises: a filter box 2 arranged on one side of the coal-fired furnace 1, an outlet pipe plugged into the side wall of the filter box 2, a first solenoid valve installed on the outlet pipe, a first filter screen 16 fixedly installed on the inner wall of the outlet pipe, and a water spray assembly for performing swing water spray filtering on hydrogen;

[0026] The dual cooperation of water spray filtration and filtration by the first filter 16 improves the filtration efficiency of the coal gas, enhances the filtration effect of the coal gas, and makes the purity of the coal gas higher.

[0027] The water spray assembly includes: an annular tube 12 fixedly mounted on the top of the inner cavity of the filter box 2, a hose 13 plugged into the bottom of the annular tube 12, a nozzle 14 plugged into the bottom end of the hose 13, a linkage spring 15 fixedly mounted between the nozzle 14 and the inner wall of the filter box 2, a water tank 6 and a water pump 7 fixedly mounted on the outside of the filter box 2, a water outlet pipe plugged between the water tank 6 and the annular tube 12, a second solenoid valve mounted on the water outlet pipe, a water pipe plugged between the water tank 6 and the water pump 7, a water inlet pipe plugged into the side wall of the water pump 7 and the filter box 2, a second filter 17 fixedly mounted on the inner wall of the water inlet pipe, a swing unit for driving the nozzle 14 to swing inwards and downwards, and a cleaning unit for cleaning the first filter 16 and the second filter 17;

[0028] By opening the first solenoid valve and the second solenoid valve, and starting the motor 3 and the water pump 7, the water in the inner cavity of the water tank 6 enters the inner cavity of the annular tube 12 through the water outlet pipe, flows into the inner cavity of the nozzle 14 through a plurality of hoses 13, and is sprayed out through a plurality of nozzles 14, so that the ash in the coal gas can be cleaned. Since the plurality of nozzles 14 are evenly distributed in an annular shape at the bottom of the annular tube 12, the water flow is sprayed more evenly, so that the coal gas is fully in contact with the water flow, thereby improving the cleaning effect of the ash in the coal gas, and the ash in the coal gas falls into the bottom of the inner cavity of the filter box 2 along with the water flow.

[0029] The swing unit includes: a motor 3 fixedly mounted on the top of the filter box 2, a rotating rod 4 fixedly mounted on the power output shaft of the motor 3, a threaded portion near the top of the outer edge of the rotating rod 4, a threaded block 8 threadedly mounted on the outer edge of the rotating rod 4, a limiting rod 9 penetrating the side wall of the threaded block 8, a limiting block 10 fixedly mounted at the bottom end of the limiting rod 9, and a linkage rod 11 hinged between the threaded block 8 and the nozzle 14; the top end of the limiting rod 9 is fixedly mounted on the inner wall of the filter box 2;

[0030] The forward and reverse rotation of the power output shaft of the motor 3 can drive the rotating rod 4 to rotate forward and reverse, and the forward and reverse rotation of the rotating rod 4 can drive the threaded block 8 to move. The threaded block 8 can be limited by the cooperation between the limiting rod 9 and the limiting block 10, so that the threaded block 8 can move up and down. The threaded block 8 drives several connecting rods 11 to move, and the connecting rods 11 drive the adjacent nozzles 14 to move, so that several nozzles 14 swing inward or outward at the same time, increasing the range of water spraying by the nozzle 14, so that water and coal gas are fully in contact, and the impurity removal effect of coal gas is further improved;

[0031] The coal gas after water spray filtration is filtered again through the first filter 16, and the coal gas after the first filter 16 is discharged through the gas outlet pipe. Through the setting of the first filter 16, the ash in the coal gas can be filtered again, which greatly enhances the filtering effect of the coal gas and makes the coal gas higher in purity.

[0032] By setting the second filter net 17, the ash in the water flow flowing into the bottom of the inner cavity of the filter box 2 can be filtered, and the filtered water is sucked into the water tank 6 through the water pump 7, so that the water flow can be reused. At the same time, impurities in the water flow can be prevented from entering the water tank 6, saving water resources.

[0033] The cleaning unit includes: a scraper 5 fixedly mounted at the bottom end of the rotating rod 4; the scraper 5 is fitted to the inner wall of the filter box 2 and the first filter screen 16 and the second filter screen 17;

[0034] By rotating the rotating rod 4, the scraper 5 can be driven to rotate, and the inner wall of the filter box 2 can be scraped by the rotation of the scraper 5, so as to prevent ash from adhering to the inner wall of the filter box 2, and the inner wall of the filter box 2 can be cleaned. At the same time, the scraper 5 can clean the impurities attached to the first filter screen 16 and the second filter screen 17 to prevent the filter holes of the first filter screen 16 and the second filter screen 17 from being blocked. There is no need for manual cleaning, which saves time and effort, ensures the filtering effect of the first filter screen 16 and the second filter screen 17, and improves the hydrogen production efficiency.

[0035] An air inlet pipe is plugged in between the coal-fired furnace 1 and the filter box 2, and a first valve is installed on the air inlet pipe. A discharge pipe is plugged in at the bottom of the filter box 2, and a second valve is installed on the discharge pipe.

[0036] By opening the first valve, the coal gas in the coal-fired furnace 1 enters the inner cavity of the filter box 2 through the air inlet pipe, and by opening the second valve, the ash at the bottom of the filter box 2 can be discharged.

[0037] Working principle: When in use, the water in the inner cavity of the water tank 6 enters the inner cavity of the annular tube 12 through the water outlet pipe, flows into the inner cavity of the nozzle 14 through a plurality of hoses 13, and is sprayed out through a plurality of nozzles 14, so that the ash in the gas can be cleaned. Since the plurality of nozzles 14 are evenly distributed in an annular shape at the bottom of the annular tube 12, the water flow is sprayed more evenly, so that the gas is fully in contact with the water flow, and the cleaning effect of the ash in the gas is improved. The forward and reverse rotation of the power output shaft of the motor 3 can drive the rotating rod 4 to rotate forward and reverse, so that the plurality of nozzles 14 are simultaneously swung inward or outward. The movement increases the range of water spraying by the nozzle 14, so that the water and the coal gas are fully in contact, and the impurity removal effect of the coal gas is further improved. The coal gas after being filtered by the water spray is filtered again through the first filter screen 16, which greatly enhances the filtering effect of the coal gas and makes the coal gas more pure. At the same time, the scraper 5 can clean the impurities attached to the first filter screen 16 and the second filter screen 17 to prevent the filter holes of the first filter screen 16 and the second filter screen 17 from being blocked. There is no need for manual cleaning, which saves time and effort, ensures the filtering effect of the first filter screen 16 and the second filter screen 17, and improves the hydrogen production efficiency.
