Description

Technical Field

[0001] The utility model relates to the technical field of industrial kilns, in particular to a fume purification and emission device for industrial kilns. Background Art

[0002] Industrial furnace flue gas is a gas with a lot of heat generated after production. It is mixed with a lot of dust and waste gas that needs to be treated. When treating industrial furnace flue gas, it is necessary to filter out the heat and pollutants in the flue gas so that it can be discharged after meeting the national emission standards. Usually, under the action of the fan, the flue gas enters the dust collector through the air duct. According to the composition and specific gravity of the flue gas, the corresponding dust collector is selected to treat the waste gas and impurities in the flue gas.

[0003] The existing referenceable Chinese utility model patent with announcement number CN204891566U discloses a glass kiln flue gas purification device. By adding a controller, a flue gas analyzer and a flow regulating valve to the denitrification component, the supply of ammonia can be controlled according to the NOX concentration set value at the outlet of the denitrification reactor, while ensuring the NOX emission standard, the utilization rate of ammonia is improved. At the same time, a heat exchanger is provided at the outlet of the desulfurization equipment to convert the heat of the high-temperature flue gas output from the denitrification reactor to the outlet of the desulfurization equipment, thereby increasing the temperature of the flue gas output from the desulfurization equipment, thereby increasing the buoyancy of the flue gas, alleviating the corrosion of the flue and chimney downstream of the desulfurization equipment, and reducing the waste of heat while increasing the service life of the equipment.

[0004] Existing flue gas purification and emission equipment for industrial kilns generally directly purifies and discharges the flue gas discharged from the industrial kilns. However, the temperature of the flue gas discharged from the industrial kilns is relatively high, and the concentration of particulate dust in the smoke is relatively high. Direct purification through the purification device can easily cause the filter element inside the purification device to become clogged, resulting in a reduction in the service life of the filter element of the purification device, which requires frequent replacement. At the same time, the high-temperature flue gas can easily damage the purification device. Utility Model Content

[0029] A filtering mechanism is fixedly installed on one side of the confluence pipe 1, and the filtering mechanism includes: a side plate 2 installed on one side of the confluence pipe 1, a filter box 21 is fixedly installed on one side of the side plate 2, a sewage outlet 22 is fixedly installed on the inner bottom of the filter box 21, two atomizing water curtain nozzles 23 are fixedly installed on the left side of the inner top of the filter box 21, a rotating nozzle 24 is fixedly installed on the right side of the inner top of the filter box 21, a water washing filter 25 is fixedly installed on one side of the inner part of the filter box 21, a diverter box 26 is fixedly installed on the top of the filter box 21, and a connecting pipe 27 is fixedly installed on one side of the diverter box 26.

[0030] Specifically, the filtering mechanism is a structure used for the industrial furnace flue gas purification and emission equipment to perform preliminary filtering and cooling of the flue gas. The flue gas is cooled by the atomized water curtain sprayed by two atomized water curtain nozzles 23, and the impurities inside the flue gas are adsorbed by the atomized water curtain. After being filtered by the water washing filter 25, it is sent into the purifier body 4. The rotating nozzle 24 is used to rotate and spray water to flush the impurities adsorbed on the surface of the water washing filter 25, and the sewage is sent into the collection box 3 through the sewage outlet 22, thereby improving the practicability of the industrial furnace flue gas purification and emission equipment.

[0031] A collecting mechanism is fixedly installed at the bottom of the filtering mechanism, and the collecting mechanism includes: a collecting box 3 installed at the bottom of the filtering box 21 , and a water pump 31 is fixedly installed on one side of the collecting box 3 .

[0032] Two support plates 32 are fixedly installed on both sides of the interior of the collection box 3 , and a support block 33 is movably connected to the top of the support plate 32 .

[0033] Two filter plates 34 are fixedly mounted inside the support block 33 , a connecting plate 35 is fixedly mounted on one side of the support block 33 , and a handle 36 is fixedly mounted on one side of the connecting plate 35 .

[0034] Specifically, the collecting mechanism is a collecting structure for the flue gas purification and emission equipment for industrial kilns. The sewage sent into the sewage outlet 22 is filtered through the two filter plates 34 inside the support block 33, and the impurities inside the sewage are filtered out and sent to the bottom of the collecting box 3. The water is pumped out by the water pump 31 and circulated. Pulling the handle 36 can drive the connecting plate 35 to take out the filter plate 34, thereby cleaning the filter plate 34, thereby improving the practicability of the flue gas purification and emission equipment for industrial kilns.

[0035] A purification mechanism is fixedly installed on one side of the filter mechanism, and the purification mechanism includes: a purifier body 4 installed on one side of the filter box 21, and an air detector 41 is fixedly installed on one side of the top of the purifier body 4.

[0036] A control valve 42 is fixedly installed on the top of the air detector 41 , a smoke exhaust port 43 is fixedly installed on the top of the control valve 42 , and a circulation pipe 44 is fixedly installed on one side of the control valve 42 .

[0037] Specifically, the purification mechanism is a purification structure of the flue gas purification and emission equipment for the industrial kiln. After the flue gas is purified by the purifier body 4, the flue gas is detected by the air detector 41. When the flue gas reaches the emission standard, the flue gas is sent to the exhaust port 43 for discharge through the control valve 42. When the flue gas does not meet the standard, the flue gas is sent to the circulation pipe 44 through the control valve 42 and then to the confluence pipe 1 for re-filtration, thereby improving the practicality of the flue gas purification and emission equipment for the industrial kiln.

[0038] Working principle: First, the smoke inside the industrial kiln main body 13 is discharged through the smoke outlet 11, and the smoke is sent to the filter box 21 through the confluence pipe 1. The water at the bottom of the collecting box 3 is sent to the diverter box 26 through the connecting pipe 27 by the water pump 31. The water is divided into three parts by the diverter box 26 and sent to the two atomizing water curtain nozzles 23 and one rotary nozzle 24. The water flow is atomized by the two atomizing water curtain nozzles 23 and sprayed out in the form of a water curtain. The high-temperature smoke is cooled by the two atomizing water curtains, and the impurities and particles in the high-temperature smoke are adsorbed by the water curtain, thereby reducing the concentration of the smoke. The smoke is filtered by the water washing filter 25. The filtered smoke enters the purifier main body 4, and the direction of the water flow spray is controlled by the rotary nozzle 24, so as to wash the particulate impurities adsorbed on the surface of the water washing filter 25, and then discharged through the sewage outlet 2. The sewage in the filter box 21 is sent into the collection box 3, and the impurities in the sewage are filtered through the two filter plates 34 in the support block 33 to prevent the impurities from clogging the nozzle during recycling. The filtered water enters the bottom of the collection box 3 for recycling. When the filter plate 34 needs to be cleaned, the handle 36 is pulled to drive the connecting plate 35 to move outward, so as to take out the filter plate 34. After cleaning, the support block 33 is inserted into the collection box 3 and supported by the two support plates 32. The flue gas after preliminary filtration enters the purifier body 4 for filtration. After filtration, it is detected by the air detector 41. When the detection result reaches the emission standard, it is sent to the exhaust port 43 through the control valve 42 and discharged. When the flue gas does not meet the standard, the flue gas is sent to the circulation pipe 44 through the control valve 42, so that the flue gas enters the confluence pipe 1 for re-filtration.
