Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat boilers, and in particular relates to a fume purification structure of a waste heat double furnace. Background Art

[0002] Waste heat boiler, as the name implies, refers to a boiler that utilizes the waste heat in waste gas, waste materials or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain temperature. Oil-fired boilers, gas-fired boilers and coal-fired boilers with smoke boxes and flues that recover waste heat are also called waste heat boilers. Waste heat boilers can produce hot water or steam through waste heat recovery to supply other work sections. When the waste heat boiler has used up the heat of the remaining flue gas, it will be discharged to the outside. The waste heat double furnace is a dual-burning furnace using coal gas and natural gas.

[0003] A search of CN220152771U discloses a flue gas purification structure for a waste heat boiler. Through a limiting ring fixedly connected to the left end of the air inlet pipe and a polytetrafluoroethylene sealing ring sleeved inside the limiting ring, when the device needs to be docked on the outside of the exhaust pipe of the waste heat boiler, the exhaust pipe of the waste heat boiler is first sleeved on the inside of the air inlet pipe through the limiting ring and the polytetrafluoroethylene sealing ring, so that the waste heat boiler is docked with the device. After the docking is completed, the exhaust pipe of the waste heat boiler is sealed and anti-corrosion strengthened by the polytetrafluoroethylene sealing ring, thereby improving the protection effect of the exhaust pipe of the waste heat boiler.

[0004] After the purification structure sprays and adsorbs the flue gas to remove impurities, the spray water does not have a mechanism to filter and purify it, so a constant supply of new spray water is needed, which will cause a huge waste of water resources. Therefore, it is necessary to filter the water after spraying and then recycle it to save water resources.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to solve the above technical problem that after the purification structure sprays and adsorbs the flue gas to remove impurities, there is no mechanism to filter and purify the spray water, which will result in the need to use new spray water continuously, which will cause a great waste of water resources. Therefore, it is necessary to filter the water after spraying and then recycle it to save water resources. The basic concept of the technical solution adopted by the utility model is:

[0007] A flue gas purification structure for a waste heat double furnace, comprising a purification box;

[0008] A support leg fixedly connected to the bottom end of the purification box, a spray filtration circulation mechanism is arranged inside the purification box, a purification mechanism is arranged on one side of the spray filtration circulation mechanism, and the spray filtration circulation mechanism includes a water tank connected to the top end of the purification box:

[0009] The outer wall of the water tank is connected to a suction pump, a suction pipe is connected to an output end of one side of the suction pump, a spray head is connected to the top of the inner wall of the purification box, a mounting groove is provided on the inner wall of the purification box, a filter plate is connected with the inner wall of the mounting groove, the filter plate is fixedly connected with a fixing plate at one end away from the mounting groove, a connecting block is fixedly connected with the top of the fixing plate, a sliding hole is provided on the top of the connecting block, a spring is fixedly connected to the bottom end of the inner wall of the sliding hole, a block is fixedly connected to one end of the spring away from the sliding hole, the outer wall of the purification box is fixedly connected to the card plate, a connecting pipe is connected to the outer wall of the purification box, a fan is connected to the outer wall of the purification box at one end away from the connecting pipe, and an exhaust pipe is connected to the output end of the fan away from one end of the purification box.

[0010] As a preferred embodiment of the utility model, the purification mechanism includes a placement groove opened at the bottom end of the inner wall of the purification box, the inner wall of the placement groove is clamped with a filter frame, the top of the filter frame is opened with slots, the number of slots is three, the inner walls of the slots are respectively clamped with a filter cotton layer, an activated carbon layer and a zeolite layer, and the outer wall of the filter frame is fixedly connected with a rubber sealing sleeve.

[0011] As a preferred embodiment of the utility model, the inner wall of the installation groove fits closely with the outer wall of the filter plate, the number of the clamping blocks is two, and the clamping blocks are distributed at the upper and lower ends of the fixing plate in an upper and lower symmetrical structure.

[0012] As a preferred embodiment of the present invention, a slot is provided on the outer wall of the card plate, a card hole is provided on the inner wall of the slot, and the inner wall of the card hole fits snugly with the top of the card block.

Then the spray water passing through the flue gas will flow downward, and filter through the filter plate to remove impurities adsorbed in the spray water. The spray water after filtering will accumulate at the bottom of the inner wall of the purification box, then starts the suction pump, and then transmits the spray water to the water tank again through the suction pipe, so that it can be recycled. Spraying water saves water resources. When the filter plate needs to be replaced or cleaned, you only need to use a greater force to pull the fixing plate outward, thereby driving the connecting block to move outward. When the connecting block moves, it can drive the clamping block to move. At this time, the clamping block will be squeezed by the inner wall of the clamping hole opened on the inner wall of the clamping plate, and then move downward to squeeze and compress the spring, so that the clamping block is separated from the limiting relationship between the clamping hole, thereby completing the disassembly of the filter plate. When installing, you only need to insert the filter plate into it, move the clamping block to the position of the clamping hole and clamp it into it, and the installation can be completed.

[0018] The utility model uses the filter frame and the filter cotton layer of the first layer of the filter frame to filter the smoke again, and then the activated carbon layer can remove odor and harmful substances from the smoke, and then the last layer of the zeolite layer further absorbs the harmful substances to complete the filtering of the smoke, and finally discharges it through the exhaust pipe. When it is necessary to replace the internal filter layer, the filter frame is directly pulled out to make the rubber sealing sleeve detach from the sealing groove opened on the top of the purification box, and then the filter layers are pulled out of the filter frame one by one for replacement, and the inside of the filter frame can be cleaned after being pulled out.

A spray head 314 is connected to the top of the inner wall of the purification box 1, and an installation groove 315 is opened on the inner wall of the purification box 1. The inner wall of the installation groove 315 is connected with a filter. Plate 316, the filter plate 316 is fixedly connected to a fixing plate 317 at one end away from the mounting groove 315, the fixing plate 317 is fixedly connected to a connecting block 318 at the top, a sliding hole is provided at the top of the connecting block 318, a spring 319 is fixedly connected to the bottom end of the inner wall of the sliding hole, the spring 319 is fixedly connected to a clamping block 3110 at one end away from the sliding hole, a clamping plate 3111 is fixedly connected to the outer wall of the purification box 1, a connecting pipe 3112 is provided on the outer wall of the purification box 1, a fan 3113 is provided on the outer wall of the purification box 1 away from the connecting pipe 3112, and an exhaust pipe 3114 is provided on the output end of the fan 3113 away from the purification box 1.

[0028] Furthermore, the inner wall of the mounting groove 315 fits snugly with the outer wall of the filter plate 316, and there are two blocks 3110, which are distributed at the upper and lower ends of the fixing plate 317 in an upper and lower symmetrical structure, thereby ensuring the tight fit of the filter plate 316 after being inserted into the inner wall of the mounting groove 315, thereby improving the installation stability of the filter plate 316.

[0029] Furthermore, a slot is provided on the outer wall of the card plate 3111, and a card hole is provided on the inner wall of the slot. The inner wall of the card hole fits snugly with the top of the card block 3110, thereby ensuring the fit of the top of the card block 3110 after being inserted into the inner wall of the card hole, thereby further ensuring the stability of the filter plate 316 after installation.

[0030] Furthermore, the bottom end of the block 3110 is cylindrical, and the top end of the block 3110 is arc-shaped, so that when the block 3110 is squeezed, it can move downward on the inner wall of the sliding hole. At the same time, the block 3110 is set to an arc shape so that it can directly release the limiting effect with the inner wall of the hole after using greater force.

[0031] The purification mechanism 32 includes a placement groove 321 opened at the bottom end of the inner wall of the purification box 1, and a filter frame 322 is placed on the inner wall of the placement groove 321. A slot is opened at the top of the filter frame 322. The number of the slots is three. The inner walls of the slots are respectively clamped with a filter cotton layer 324, an activated carbon layer 325 and a zeolite layer 326. The outer wall of the filter frame 322 is fixedly connected with a rubber sealing sleeve 323.

[0032] Furthermore, ventilation holes are provided on the left and right sides of the filter frame 322 , and the inner wall of the slot provided at the top of the filter frame 322 fits snugly with the outer walls of the three filter layers, so that the smoke can be filtered and purified through the interior of the filter frame 322 .

[0033] Furthermore, a sealing groove is provided at the top of the purification box 1, and the outer wall of the rubber sealing sleeve 323 is larger than the inner wall of the sealing groove. When the rubber sealing sleeve 323 is inserted into the sealing groove, it can be squeezed by the sealing groove, and then fill the inner wall of the sealing groove through its own rebound effect to complete the sealing effect.

[0034] The implementation principle of the flue gas purification structure of a waste heat double furnace in this embodiment is as follows: first, fill the water tank 311 with spray water, then connect the connecting pipe 3112 with the exhaust pipe 3114 of the waste heat furnace, then start the fan 3113 to suck the flue gas into the purification box 1, and synchronously start the spray head 314 to spray, absorb and remove impurities on the flue gas entering the purification box 1, then the spray water passing through the flue gas will flow downward, and filter through the filter plate 316 to remove impurities adsorbed in the spray water. The spray water after filtration will accumulate at the bottom end of the inner wall of the purification box 1, then start the suction pump 312, and then transmit the spray water to the water tank 311 again through the suction pipe 313, so as to The spray water can be recycled to save water resources. When the filter plate 316 needs to be replaced or cleaned, it is only necessary to use a greater force to pull the fixing plate 317 outward, thereby driving the connecting block 318 to move outward. When the connecting block 318 moves, it can drive the clamping block 3110 to move. At this time, the clamping block 3110 will be squeezed by the inner wall of the clamping hole opened on the inner wall of the clamping plate 3111, and then move downward to squeeze and compress the spring 319, so that the clamping block 3110 is separated from the limiting relationship between the clamping hole, thereby completing the disassembly of the filter plate 316. During installation, it is only necessary to insert the filter plate 316 into it, so that the clamping block 3110 moves to the position of the clamping hole and is clamped into it, and the installation can be completed.

[0035] Subsequently, the smoke after impurity removal will pass through the partition inside the purification box 1 and then through the filter frame 322. The filter cotton layer 324 of the first layer of the filter frame 322 can remove impurities and filter the smoke again, and then the activated carbon layer 325 can remove odors and harmful substances from the smoke. Subsequently, the last layer of the zeolite layer 326 further absorbs harmful substances to complete the filtering of the smoke, and finally it can be discharged through the exhaust pipe 3114. When it is necessary to replace the internal filter layer, the filter frame 322 is directly pulled out to make the rubber sealing sleeve 323 detach from the sealing groove opened at the top of the purification box 1, and then the filter layers are pulled out of the filter frame 322 one by one for replacement. After being pulled out, the inside of the filter frame 322 can also be cleaned.
