Description

Technical Field

[0001] This invention belongs to the field of flue gas treatment technology, and specifically relates to a denitrification treatment device for flue gas from biomass energy stoves. Background Art

[0002] In the denitrification of flue gas from biomass energy stoves, filtration pretreatment equipment is mainly used to solve the problem of special pollutants in biomass combustion flue gas. When biomass fuel is burned, a large amount of tar, alkali metals, chlorides and high concentrations of particulate matter are produced. These substances can cover the catalyst surface or cause chemical poisoning, resulting in a significant decrease in denitrification efficiency. Filtration pretreatment equipment can efficiently remove particulate matter from the flue gas.

[0003] The current flue gas denitrification equipment still has the following problems: Although some flue gas filtration equipment is also equipped with a cleaning structure, the cleaned particles are easy to clog the filter screen again, making it impossible to collect the cleaned particles and affecting the cleaning effect of the filter screen; the equipment cannot automatically detect the weight of the collected particles before starting up, which makes it easy to need to stop and clean the equipment after normal start-up due to a large amount of particles, affecting the normal treatment of flue gas. Summary of the Invention

[0004] To address the aforementioned technical problems in existing technologies, this invention provides a biomass energy stove flue gas denitrification treatment device, comprising a movable mounting section, a pretreatment section, and a start-up detection section. Particulate matter falls into the lower half of a conical collection frame, ensuring the upper half of a metal filter screen remains relatively clean, thus guaranteeing normal flue gas flow. When there is a large amount of particulate matter in the conical collection frame, the total weight of the movable mounting section, the pretreatment section, and the particulate matter exceeds the elastic limiting force of the two elastic connecting rods, allowing the connecting frame to automatically separate from the stove connecting pipe, prompting the operator to automatically clean the particulate matter and preventing the equipment from stopping due to excessive particulate matter after operation. This solves the technical problems of cleaned particulate matter easily re-clogging the filter screen and the need to stop the equipment for cleaning due to excessive particulate matter after normal startup.

[0011] Furthermore, the pretreatment section also includes a metal filter screen; the conical collection rack is fixedly installed inside the movable mounting tube; the metal filter screen has a total of one ring, and the ring of metal filter screen is fixedly installed on the conical collection rack.

[0012] Furthermore, the pretreatment section also includes a positioning retaining ring, an installation mesh tray, and a cleaning scraper; the positioning retaining ring is fixedly installed at the bottom end of the circular installation shaft; the installation mesh tray is fixedly installed on the outside of the circular installation shaft; the cleaning scraper has a ring, and the ring of cleaning scrapers is fixedly installed on the installation mesh tray, and the ring of cleaning scrapers also contacts the inner wall of the ring of metal filter screen.

[0013] Furthermore, the start-up detection unit includes a rectangular mounting bracket, a movable mounting base, a circular limit rod, and a control switch A; the rectangular mounting bracket is fixedly installed on the right side of the stove connecting pipe; the movable mounting base is slidably installed inside the rectangular mounting bracket; the circular limit rod is fixedly installed on the left side of the movable mounting base, and the left end of the circular limit rod is inserted into the limit hole; the control switch A is fixedly installed inside the movable mounting base, and the control switch A is also electrically connected to the delay controller.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the motor is working, the drive shaft drives the guide impeller to rotate, which guides the flue gas and facilitates its discharge. The two elastic connecting rods provide an elastic connection for the connecting frame, facilitating its subsequent disassembly and installation. When the connecting frame is disassembled or installed, it can press the two elastic connecting rods outward, causing them to automatically separate from the two arc-shaped slots. When the connecting frame is completely removed or installed, the two elastic connecting rods automatically return to their original positions under the action of two return springs B.

[0017] 2. When the metal filter screen is severely clogged, the resistance of the flue gas passing through the metal filter screen increases. When the resistance of the flue gas passing through the metal filter screen increases, the movable mounting tube slides downward, causing the return spring A to be compressed to a certain extent. When the movable mounting tube slides downward, the circular mounting shaft can rotate under the action of two circular drive rods and two spiral grooves.

[0018] Furthermore, when the circular mounting shaft rotates under the action of two circular drive rods and two spiral grooves, a ring of cleaning scrapers can automatically scrape off the particles on a ring of metal filter screen, causing the particles to fall into the lower half of the conical collection frame, ensuring that the upper half of the ring of metal filter screen is in a relatively clean state and ensuring the normal flow of flue gas; when the ring of metal filter screen is cleaned, the resistance of flue gas passing through the ring of metal filter screen returns to normal, at which point the movable mounting tube automatically resets upward under the action of a ring of reset spring A.

[0019] 3. The circular limiting rod of this invention provides secondary positioning for the connecting frame, making the connection between the connecting frame and the stove connecting pipe more secure. When the operator starts the motor, the movable mounting seat needs to be pulled to the right first. When the movable mounting seat moves to the right, the control switch A separates from the rectangular mounting frame. At the same time, the left end of the circular limiting rod separates from the limiting hole. When there are many particles in the conical collecting rack, the total weight of the movable mounting part, the pretreatment part, and the particles is greater than the elastic limiting force of the two elastic connecting rods, allowing the connecting frame to automatically separate from the stove connecting pipe. When there are few particles in the conical collecting rack, the total weight of the movable mounting part, the pretreatment part, and the particles is less than the elastic limiting force of the two elastic connecting rods, and the connecting frame cannot automatically separate from the stove connecting pipe. This achieves automatic detection of particle weight before equipment use, prompting the operator to automatically clean the particles and preventing the equipment from stopping due to excessive particles after operation.

[0020] In addition, when the operator turns off the motor, there is no need to pull out the movable mounting base completely. When the control switch B is separated from the rectangular mounting bracket, the left end of the circular limit rod is still inserted in the limit hole, ensuring that the connecting assembly bracket will not fall off. When the operator releases the movable mounting base, the movable mounting base automatically returns to the rectangular mounting bracket under the action of the two return springs C.

[0044] Its specific function is as follows: Since the drive shaft 104 is fixedly installed on the output shaft of the motor 103, and the guide impeller 105 is located inside the stove connecting pipe 101, and the guide impeller 105 is also fixedly connected to the right end of the drive shaft 104, when the motor 103 works, the drive shaft 104 drives the guide impeller 105 to rotate, which guides the flue gas and facilitates its discharge. Furthermore, since the two elastic connecting rods 302 are slidably installed on the two V-shaped frames 301 and the stove connecting pipe 101, and the outer ends of the two elastic connecting rods 302 are hemispherical, and the two elastic connecting rods... The outer end of the connecting rod 302 is inserted into the two arc-shaped slots 2011, which provides an elastic connection for the connecting assembly frame 201, facilitating the subsequent disassembly and installation of the connecting assembly frame 201. When the operator disassembles or installs the connecting assembly frame 201, the connecting assembly frame 201 can squeeze the two elastic connecting rods 302 outward, causing the two elastic connecting rods 302 to automatically separate from the two arc-shaped slots 2011. When the connecting assembly frame 201 is completely removed or installed in place, the two elastic connecting rods 302 can automatically return to their original position under the action of the two return springs B304.

[0045] In this embodiment of the disclosure, such as Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the movable mounting part 200 includes: a connecting assembly frame 201 and a circular drive rod 202; the connecting assembly frame 201 is slidably mounted on the stove connecting pipe 101, and two arc-shaped slots 2011 are provided on the connecting assembly frame 201; two circular drive rods 202 are provided, and the two circular drive rods 202 are fixedly mounted on the inner wall of the connecting assembly frame 201; the movable mounting part 200 also includes: a T-shaped stabilizer 203, a mounting ring 204, and a reset mounting rod A205; the T-shaped stabilizer 203 is fixedly mounted on the inner wall of the connecting assembly frame 201, and a limit hole 2031 is provided on the T-shaped stabilizer 203; the mounting ring 204 is fixedly mounted on the outside of the connecting assembly frame 201; the reset mounting rod A205 has one... The movable mounting part 200 also includes: a movable mounting tube 206, a limiting ring A207, and a return spring A208; the movable mounting tube 206 is fixedly installed at the bottom of the one-circle reset mounting rod A205, and the inner wall of the movable mounting tube 206 contacts the outer wall of the connecting assembly frame 201; the limiting ring A207 is provided in one circle, and the one-circle limiting ring A207 is fixedly installed at the top of the one-circle reset mounting rod A205; the return spring A208 is provided in one circle, and the one-circle return spring A208 is sleeved on the outside of the one-circle reset mounting rod A205, and the one-circle return spring A208 is located between the mounting ring 204 and the one-circle limiting ring A207;

[0046] The pretreatment unit 400 includes: a conical collection frame 401, a metal filter screen 402, and a circular mounting shaft 403; the conical collection frame 401 is fixedly installed inside the movable mounting tube 206; the metal filter screen 402 has one ring, and the ring of metal filter screen 402 is fixedly installed on the conical collection frame 401; the circular mounting shaft 403 is rotatably installed on the conical collection frame 401, and the top end of the circular mounting shaft 403 has two spiral grooves 4031, and two circular drive rods 202. Inserted into two spiral grooves 4031; the pretreatment section 400 also includes: a positioning retaining ring 404, an installation mesh tray 405, and a cleaning scraper 406; the positioning retaining ring 404 is fixedly installed at the bottom end of the circular installation shaft 403; the installation mesh tray 405 is fixedly installed on the outside of the circular installation shaft 403; the cleaning scraper 406 is provided in a ring, and the ring of cleaning scrapers 406 is fixedly installed on the installation mesh tray 405, and the ring of cleaning scrapers 406 also contacts the inner wall of the ring of metal filter screen 402;

[0047] Its specific function is as follows: Since the conical collection rack 401 is fixedly installed inside the movable mounting tube 206, and a metal filter 402 is fixedly installed on the conical collection rack 401, and a return spring A208 is located between the mounting ring 204 and the limiting ring A207, when the metal filter 402 is severely blocked, the resistance of the flue gas passing through the metal filter 402 increases; when the resistance of the flue gas passing through the metal filter 402 increases, the movable mounting tube 206 slides downward, causing the return spring A208 to be compressed to a certain extent; since the two circular drive rods 202 are fixedly installed on the inner wall of the connecting assembly frame 201, and the top of the circular mounting shaft 403 has two spiral grooves 4031, and the two circular drive rods 202 are inserted into the two spiral grooves 4031, when the movable mounting tube 206 slides downward, the circular mounting shaft 403 can rotate under the action of the two circular drive rods 202 and the two spiral grooves 4031;

[0048] Furthermore, since the mounting tray 405 is fixedly mounted on the outside of the circular mounting shaft 403, and a ring of cleaning blades 406 is fixedly mounted on the mounting tray 405, and the ring of cleaning blades 406 also contacts the inner wall of the ring of metal filter screen 402, when the circular mounting shaft 403 rotates under the action of the two circular drive rods 202 and the two spiral grooves 4031, the ring of cleaning blades 406 can automatically scrape off the particles on the ring of metal filter screen 402, causing the particles to fall into the lower half of the conical collection rack 401. The upper part of the metal filter 402 is kept relatively clean, ensuring normal flow of flue gas. Since the return spring A208 is sleeved outside the return mounting rod A205 and located between the mounting ring 204 and the limiting ring A207, when the metal filter 402 is cleaned, the resistance of the flue gas passing through it returns to normal. At this time, the movable mounting tube 206 automatically returns to its original position under the action of the return spring A208.

[0049] In this embodiment of the disclosure, such as Figure 9 and Figure 10As shown, the start-up detection unit 500 includes: a rectangular mounting bracket 501, a movable mounting base 502, a circular limit rod 503, and a control switch A504; the rectangular mounting bracket 501 is fixedly installed on the right side of the stove connecting pipe 101; the movable mounting base 502 is slidably installed inside the rectangular mounting bracket 501; the circular limit rod 503 is fixedly installed on the left side of the movable mounting base 502, and the left end of the circular limit rod 503 is inserted into the limiting circular hole 2031; the control switch A504 is fixedly installed inside the movable mounting base 502, and the control switch A504 is also electrically connected to the delay controller 600; the start-up detection unit 500 also includes: a control... The system includes a switch B505, a reset mounting rod B506, and a reset spring C507. The control switch B505 is fixedly installed inside the movable mounting base 502 and is also electrically connected to the delay controller 600. There are two reset mounting rods B506, which are fixedly installed on the rectangular mounting bracket 501 and are slidably connected to the movable mounting base 502. There are two reset springs C507, which are sleeved on the outside of the two reset mounting rods B506 and are located on the right side of the movable mounting base 502.

[0050] Its specific function is as follows: Because the movable mounting base 502 is slidably installed inside the rectangular mounting bracket 501, and the circular limiting rod 503 is fixedly installed on the left side of the movable mounting base 502, with the left end of the circular limiting rod 503 inserted into the limiting circular hole 2031, it provides secondary positioning for the connecting assembly bracket 201, making the connection between the connecting assembly bracket 201 and the stove connecting pipe 101 more secure; Furthermore, because the control switch A504 is fixedly installed inside the movable mounting base 502, and the control switch A504 is also electrically connected to the delay controller 600, when the operator starts the motor 103, the movable mounting base 502 needs to be pulled to the right first. When the movable mounting base 502 moves to the right, the control switch A504 separates from the rectangular mounting bracket 501; When the left end of the circular limiting rod 503 separates from the limiting circular hole 2031, and there are many particles in the conical collecting rack 401, the total weight of the movable mounting part 200, the pretreatment part 400 and the particles is greater than the elastic limiting force of the two elastic connecting rods 302, so that the connecting rack 201 and the stove connecting pipe 101 can automatically separate. When there are few particles in the conical collecting rack 401, the total weight of the movable mounting part 200, the pretreatment part 400 and the particles is less than the elastic limiting force of the two elastic connecting rods 302, so the connecting rack 201 and the stove connecting pipe 101 cannot automatically separate. This realizes the automatic detection of the particle weight before the equipment is used, which can prompt the staff to clean the particles automatically and avoid the equipment from stopping due to too many particles after it has been working.

[0051] Furthermore, because control switch B505 is fixedly installed inside the movable mounting base 502, and control switch B505 is also electrically connected to the delay controller 600, and the position of control switch B505 is further to the right than the position of control switch A504, when the operator turns off motor 103, the operator does not need to pull out the movable mounting base 502 completely. When control switch B505 is separated from the rectangular mounting bracket 501, the left end of the circular limit rod 503 is still inserted in the limit circular hole 2031, ensuring that the connecting assembly bracket 201 will not fall off; and because the two composite... The positioning rod B506 is fixedly installed on the rectangular mounting bracket 501, and two return springs C507 are sleeved on the outside of the two return mounting rods B506. The two return springs C507 are located on the right side of the movable mounting seat 502. When the operator releases the movable mounting seat 502, the movable mounting seat 502 automatically returns to the rectangular mounting bracket 501 under the action of the two return springs C507. The operator can fix baffles on the front and rear sides of the rectangular mounting bracket 501 to prevent unfiltered flue gas from being discharged through the holes on the rectangular mounting bracket 501.

[0052] The specific usage and function of this embodiment are as follows:

[0053] In use, the operator first connects the stove connecting pipe 101 to the flue gas pipe on the biomass energy stove using bolts. The two elastic connecting rods 302 provide an elastic connection for the connecting assembly frame 201, facilitating its subsequent disassembly and installation. When the operator disassembles or installs the connecting assembly frame 201, the frame can press the two elastic connecting rods 302 outward, causing them to automatically separate from the two arc-shaped slots 2011. When the connecting assembly frame 201 is completely removed or installed, the two elastic connecting rods 302 automatically return to their original position under the action of the two return springs B304.

[0054] When the operator starts the motor 103, the movable mounting base 502 needs to be pulled to the right first. When the movable mounting base 502 moves to the right, the control switch A504 separates from the rectangular mounting bracket 501; at the same time, the left end of the circular limit rod 503 separates from the limit hole 2031. When there are many particles in the conical collection rack 401, the total weight of the movable mounting part 200, the pretreatment part 400, and the particles is greater than the elastic limiting force of the two elastic connecting rods 302, causing the connecting assembly rack 201 to connect with the stove. Pipe 101 can automatically separate; when there are few particles in the conical collection rack 401, the total weight of the movable mounting part 200, the pretreatment part 400, and the particles is less than the elastic limiting force of the two elastic connecting rods 302, and the connecting combination rack 201 and the stove connecting pipe 101 cannot automatically separate, realizing automatic detection of particle weight before equipment use, prompting the staff to automatically clean the particles, and avoiding equipment shutdown due to excessive particles after operation; when the metal filter screen 402 is severely clogged, the resistance of flue gas passing through the metal filter screen 402 increases; when the resistance of flue gas passing through the metal filter screen 402 increases, the movable mounting pipe 206 slides downward, causing the return spring A208 to be compressed to a certain extent; when the movable mounting pipe 206 slides downward, the circular mounting shaft 403 can rotate under the action of the two circular drive rods 202 and the two spiral grooves 4031; when the circular mounting shaft 403 rotates under the action of the two circular drive rods 202 and the two spiral grooves 4031 When rotation occurs, the cleaning blades 406 automatically scrape off the particles on the metal filter screen 402, causing the particles to fall into the lower half of the conical collection rack 401, ensuring that the upper half of the metal filter screen 402 is relatively clean and ensuring the normal flow of flue gas. When the metal filter screen 402 is cleaned, the resistance of the flue gas passing through the metal filter screen 402 returns to normal. At this time, the movable mounting tube 206 automatically returns to its original position under the action of the return spring A208.

[0055] When the operator turns off the motor 103, there is no need to pull out the movable mounting base 502 completely. When the control switch B505 is separated from the rectangular mounting bracket 501, the left end of the circular limit rod 503 is still inserted in the limit circular hole 2031, ensuring that the connecting assembly bracket 201 will not fall off. When the operator releases the movable mounting base 502, the movable mounting base 502 automatically returns to the rectangular mounting bracket 501 under the action of the two return springs C507.

[0056] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
