[0002] The working principle of the environmental protection box will vary depending on its specific purpose and design; for example, when treating sulfur-containing waste gas, sulfide may be converted into sulfate through chemical reaction. The working principle and internal structure of environmental protection boxes of different types and uses will vary, but they are all environmental protection engineering construction equipment for purifying industrial waste gas to protect the environment and human health.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1-Figure 4 The present invention provides a technical solution: an environmental protection box with high utilization rate of desulfurization and denitration catalysts, including an environmental protection box 1, an air inlet pipe 2 is fixedly connected to the right side of the environmental protection box 1, an air outlet pipe 3 is fixedly connected to the left side of the environmental protection box 1, a sliding cavity 4 is fixedly connected to one side of the inner wall of the environmental protection box 1, and a pusher assembly 7 is arranged on the inner wall of the sliding cavity 4, and also includes:

[0036] The pushing mechanism 5 comprises a connecting pipe 501 fixedly connected to one end of the air inlet pipe 2, a limiting cover 504 fixedly connected to the end of the connecting pipe 501 away from the air inlet pipe 2, sliding rings 502 are slidably connected in the slots on both sides of the inner wall of the connecting pipe 501, cleaning components 507 are arranged on both sides of the inner wall of the sliding ring 502, an impact tube 503 is fixedly connected to the bottom of the inner wall of the sliding ring 502, a cleaning ring 505 is slidably connected to the surface slot of the connecting pipe 501 through a slider, a plug 506 is inserted into the inner wall of the cleaning ring 505, and a dispersion mechanism 6 is arranged at the end of the limiting cover 504 away from the connecting pipe 501;

[0037] The cleaning component 507 includes a pushing ring 5071 rotatably connected to the inner walls of the sliding ring 502 on both sides via a rotating shaft, the bottom of the inner wall of the pushing ring 5071 is fixedly connected to an absorption chamber 5072, the bottom of the inner wall of the absorption chamber 5072 is fixedly connected to a telescopic arm 5073, the telescopic arm 5073 has a telescopic characteristic, when air pressure flows into the telescopic arm 5073, it will drive it to telescope outward and absorb particulate matter in the exhaust gas through the absorption ball 5074, the inner wall of the telescopic arm 5073 is fixedly connected to the absorption ball 5074, and the surface groove of the pushing ring 5071 is fixedly connected to an extrusion bag 5075.

[0038] The working method of the first embodiment is as follows: when the generated exhaust gas is sprayed into the interior of the environmental protection box 1 through the air intake pipe 2, the sprayed exhaust gas will first flow into the interior of the connecting pipe 501, and the telescopic device inside the connecting pipe 501 will be started first to drive the sliding ring 502 to slide on the inner wall of the connecting pipe 501. During the sliding process, the sprayed exhaust gas will push the push ring 5071, so that the push ring 5071 rotates on the inner wall of the sliding ring 502, and each rotation will cause the squeezing bag 5075 to come into contact with the surface of the impact tube 503. By squeezing the surface of the squeezing bag 5075, air pressure is generated inside the squeezing bag 5075 and flows into the interior of the absorption chamber 5072. The air pressure will drive the telescopic arm 5073 to telescope outward. When the telescopic arm 5073 telescopes outward from the inner wall of the absorption chamber 5072, the exhaust gas contained in the exhaust gas sprayed onto the surface of the push ring 5071 can be absorbed by the absorption ball 5074. Large particles are absorbed into the interior. When the air pressure inside the telescopic arm 5073 disappears, it will retract inward again into the interior of the absorption chamber 5072. The absorption chamber 5072 squeezes the absorption ball 5074, thereby squeezing the large particles inside into the interior of the cleaning ring 505. Finally, when the environmental protection box 1 finishes the purification work of the exhaust gas, the environmental protection box 1 can be opened to pull the cleaning ring 505 out of the surface slot of the connecting pipe 501, and then the plug 506 is pulled out from the interior of the cleaning ring 505, and then the interior of the cleaning ring 505 is cleaned. By setting up this mechanism, it is avoided that the traditional filter screen will not be blocked by the filter screen while cleaning the large particles contained in the exhaust gas. While reducing the large particles contained in the exhaust gas and improving the use efficiency of the catalyst, it is also convenient to clean the cleaning device regularly to avoid the problem of large particles clogging the surface of the cleaning device.

[0039] Embodiment 2: The difference from embodiment 1 is as follows: Figure 5-Figure 7 The dispersion mechanism 6 includes a connecting plate 601, which is fixedly connected to one end of the limiting cover 504, and the two sides of the connecting plate 601 are fixedly connected to the vertical plates 602, and the inner wall bottom of the vertical plates 602 is fixedly connected to the pressing tube 603, and the bottom of the connecting plate 601 is fixedly connected to the storage capsule 604, and the bottom of the storage capsule 604 is provided with a slot, and a small telescopic block is elastically connected to the slot, which will telescope inward into the storage capsule 604 and leak out of the bottom slot when squeezed, and the storage The surface of the storage bag 604 is fixedly connected with a clamping ring 605, and the inner wall of the clamping ring 605 is slidably connected with a pressure block 606. Since the pressure block 606 slides from left to right, the pressure transmitted to the inside of the three storage bags 604 is also transmitted from left to right in sequence, which means that the push-pull strips 6085 pop out from left to right in sequence. A reflux component 607 is provided at one end of the connecting plate 601 away from the limiting cover 504, and a mixing component 608 is provided on the inner wall of the connecting plate 601.

[0040] The mixing assembly 608 includes a frame 6081, which is fixedly connected to the inner wall of the connecting plate 601. Sealing blocks 6082 are rotatably connected to the inner walls of the frame 6081 on both sides through a rotating shaft. Six sealing blocks 6082 are arranged inside the two ends of the connecting plate 601. The exhaust gas is blocked by the sealing blocks 6082 inside the connecting plate 601 and stops flowing. The inner wall of the storage capsule 604 is slidably connected to a push-pull strip 6085. One end of the push-pull strip 6085 away from the inner wall of the storage capsule 604 is fixedly connected to the surface of the sealing block 6082. The push-pull strip 6085 has the characteristics of expansion and contraction. When the pressure inside the storage capsule 604 disappears, the push-pull strip 6085 will expand and contract toward the inside of the storage capsule 604. The surface of the push-pull strip 6085 is fixedly connected to a compression strip 6083, and the surface of the compression strip 6083 is fixedly connected to an absorption ring 6084.

[0041] The pusher assembly 7 includes a sliding block 701 , one end of which is slidably connected to both sides of the inner wall of the sliding cavity 4 , and a folding ring 702 is fixedly connected to the surface of the sliding block 701 .

[0042] The pushing assembly 7 also includes a rotating disk 703, the two sides of which are rotatably connected to the inner walls of the folding ring 702 via a rotating shaft, a pulling rod 704 is slidably connected to the surface of the rotating disk 703, a lower pressure column 705 is fixedly connected to the bottom of the folding ring 702, and a pushing disk 706 is fixedly connected to the bottom of the lower pressure column 705.

[0043] The working method of the second embodiment is as follows: when the large particles in the exhaust gas are removed, they will flow into the interior of the connecting plate 601 through the limiting cover 504. After the exhaust gas flows to both ends of the connecting plate 601 through the connecting plate 601, the power device inside the environmental protection box 1 is started to drive the sliding block 701 to slide on the inner wall of the sliding cavity 4. When the sliding block 701 drives the folding ring 702 to move to the interior of the vertical plate 602 while sliding, the rotating disk 703 will rotate inside the vertical plate 602, and the interior of the rotating disk 703 is injected with a catalyst. When one end of the pulling rod 704 rotates to the interior of the pressing tube 603, one end of the pulling rod 704 will be squeezed inward into the rotating disk 703. The interior of the rotating disk 703 is pressed against the inside of the rotating disk 703, thereby causing pressure to the inside of the rotating disk 703, so that the catalyst inside the rotating disk 703 is squeezed out and sprayed into the inside of the connecting plate 601 through one end of the pulling rod 704. At this time, when the sliding block 701 drives the lower pressure column 705 to move to the surface of the pressing ring 605, the pushing disk 706 is inserted into the inside of the pressure block 606, thereby pushing the pressure block 606, so that the pressure block 606 slides on the left side of the inner wall of the pressing ring 605 and then to the other side. The sliding of the pressure block 606 will generate pressure on the inside of the pressing ring 605, causing the pressing ring 605 to shrink inward and squeeze the storage capsule 604, thereby The pressure generated inside the storage bag 604 will cause the push-pull strip 6085 to pop out from the storage bag 604. When the push-pull strip 6085 pops out to the top, it will push the sealing block 6082, causing the sealing block 6082 to rotate outward inside the frame 6081. At this time, the exhaust gas will flow from the inside of the connecting plate 601 into the area blocked by the sealing block 6082. At this time, the catalyst flowing out through the rotating disk 703 will enter the area, and the catalyst will react chemically with the small particles in the exhaust gas in the area to convert them into harmless gas and then be discharged outward. The catalyst will be injected into multiple pressing tubes 603 in sequence through the rotating disk 703 and flow into the area The catalyst can be injected into the connecting plate 601 in batches. When the exhaust gas passes through the catalyst injected multiple times, the small particles inside can fully react chemically with the catalyst to improve the catalytic purification rate. When the catalyst is injected into the sealing area composed of multiple sealing blocks 6082, the catalyst will react chemically with the particulate matter in the exhaust gas, and the remaining catalyst in the sealing area that has not yet reacted will be absorbed by the absorption ring 6084 into the storage capsule 604. The catalyst inside the connecting plate 601 that has not yet reacted can be absorbed and stored, and then reused later to improve the use efficiency of the catalyst.

[0044] Example 3: Based on Example 2, continue to refer to Figure 8The reflux component 607 includes a dispersion tube 6071, both ends of which are fixedly connected to both ends of the connecting plate 601, one end of the dispersion tube 6071 is fixedly connected to the inner wall of the outlet pipe 3, a compression ball 6072 is fixedly connected to the surface of the dispersion tube 6071, an absorption groove is provided on one side of the compression ball 6072, and the absorption groove is connected to the inside of the dispersion tube 6071. Since a negative pressure cavity is provided inside the compression ball 6072, when the compression ball 6072 is subjected to pressure, it will shrink inward and generate negative pressure suction to suck the catalyst into the dispersion tube 6071 through the discharge plate 6075, a compression ring 6073 is fixedly connected to the surface of the dispersion tube 6071, a discharge rod 6074 is fixedly connected to the bottom of the compression ball 6072, a discharge plate 6075 is fixedly connected to the bottom of the discharge rod 6074, and a pop-up ring 6076 is fixedly connected to the top of the discharge plate 6075.

[0045] The working mode of the third embodiment of the present invention is as follows: the purified exhaust gas will be discharged into the dispersion pipe 6071. When the purified exhaust gas is discharged to the outside of the exhaust pipe 3 through the dispersion pipe 6071, the compression ball 6072 will absorb a part of the exhaust gas and expand outward during the discharge process, and will be squeezed with the inner wall of the compression ring 6073, so that the gas inside the compression ball 6072 is discharged into the discharge plate 6075 through the lower rod 6074. The discharge plate 6075 receives the gas and pushes the pop-up ring 6076, so that the pop-up ring 6076 expands and contracts toward the top and enters the storage capsule 604. The catalyst inside the storage capsule 604 is absorbed into the discharge plate 6075 through the pop-up ring 6076 and finally flows into the dispersion pipe 6071. By setting this component, in the process of the dispersion pipe 6071 discharging the exhaust gas to the outside, the catalyst that has not yet produced a chemical reaction in the storage capsule 604 is concentrated and utilized, and chemically reacts with the exhaust gas discharged to the outside, so as to improve the utilization rate of the residual catalyst.

[0047] S1: When the generated exhaust gas is sprayed into the interior of the environmental protection box 1 through the air inlet pipe 2, the sprayed exhaust gas will push the push ring 5071, and the large particles contained in the exhaust gas sprayed onto the surface of the push ring 5071 can be absorbed into the interior through the absorption ball 5074. The absorption cavity 5072 squeezes the absorption ball 5074, thereby squeezing the large particles inside into the interior of the cleaning ring 505, and finally the interior of the cleaning ring 505 is cleaned.

[0048] S2: Start the power device inside the environmental protection box 1 to drive the sliding block 701 to slide on the inner wall of the sliding cavity 4. When the rotating disk 703 slides to the inside of the vertical plate 602, it will contact the surface of the pressing tube 603. The catalyst will be injected into multiple pressing tubes 603 in turn through the rotating disk 703 and flow into the sealing area formed by the sealing block 6082 in the connecting plate 601. The catalyst can be injected into the inside of the connecting plate 601 in batches.

[0049] S3: After the catalyst is injected into the sealed area formed by the multiple sealing blocks 6082, the remaining catalyst in the sealed area that has not yet produced a chemical reaction will be absorbed by the absorption ring 6084 into the storage capsule 604.

[0050] S4: The purified exhaust gas will be discharged into the dispersion pipe 6071, and the catalyst inside the storage capsule 604 will be absorbed into the discharge plate 6075 through the pop-up ring 6076 and finally flow into the dispersion pipe 6071. The catalyst inside the storage capsule 604 that has not yet produced a chemical reaction will be concentrated and utilized, and will react chemically with the exhaust gas discharged to the outside.
