Description

Technical Field

[0001] This invention relates to the field of desulfurization gas transmission pipelines, and in particular to a desulfurization gas transmission pipeline with an anti-clogging structure. Background Technology

[0002] Desulfurization, broadly speaking, refers to the process of removing sulfur from fuel before combustion and desulfurizing flue gas before emissions. It is one of the important technical measures for preventing and controlling air pollution. Desulfurization methods generally include three types: pre-combustion, during-combustion, and post-combustion desulfurization. With industrial development and the improvement of people's living standards, the demand for energy is constantly increasing. SO2 in coal-fired flue gas has become a major cause of air pollution. In the desulfurization process, the exhaust gas after combustion is generally blown by a fan structure, allowing the flue gas to enter the desulfurization tower through the intake pipe for desulfurization treatment.

[0003] In the process of desulfurization towers, the intake pipes are relatively simple in structure. If the concentration of the incoming waste gas is too high, or if the waste gas contains a lot of dust, blockage can easily occur, affecting the efficiency and standards of waste gas transmission. Current technology typically involves manual scraping of the pipe's inner wall to increase cleaning effectiveness. This often requires multiple manual scrapings, resulting in high labor intensity. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and title of the invention.

[0006] Therefore, the technical problem to be solved by the present invention is that the desulfurization tower is prone to blockage during the process of inputting waste gas through the inlet pipe. In the prior art, the inner wall of the pipe is usually scraped manually. In order to increase the cleaning effect, the inner wall of the pipe often needs to be scraped manually multiple times, which results in a high labor intensity for cleaning.

[0031] Example 1

[0032] Reference Figure 1-4This embodiment provides a desulfurization gas transmission pipeline with an anti-clogging structure, including a gas transmission pipe 100, an inlet pipe 101, an outlet pipe 102, and an exhaust fan 103. The gas transmission pipe 100 is vertical. The inlet pipe 101 is fixedly connected to the circumferential surface at the bottom of the gas transmission pipe 100. The outlet pipe 102 is fixedly connected to the circumferential surface at the top of the gas transmission pipe 100. The exhaust fan 103 is disposed inside the outlet pipe 102. A filter screen is disposed on the inner wall of the gas transmission pipe 100 at a position corresponding to that of the outlet pipe 102.

[0033] The cleaning assembly 200 includes a dust scraper 201, a flushing component 202, and a moving component 203. The dust scraper 201 is disposed inside the air supply pipe 100 and located below the air inlet pipe 101. The flushing component 202 is embedded inside the dust scraper 201. The moving component 203 is embedded inside the air supply pipe 100 and is connected to the dust scraper 201.

[0034] The dust scraper component 201 includes a base plate 201a, a crossbar 201b, a long groove 201c, a vertical cylinder 201d, a column rod 201e, and a connecting rod 201f. The crossbar 201b is rotatably connected to the base plate 201a. The long groove 201c is vertically formed on the inner circumferential surface of the air supply pipe 100 and corresponds to the end position of the crossbar 201b. The crossbar 201b extends into the long groove 201c, and a gear 201b-1 is fixedly connected to its end. The long groove 201c is provided with teeth 201c-1 that are adapted to the gear 201b-1. The base plate 201a... The upper end face is provided with a movable cavity 201a-1. The vertical cylinder 201d is fixedly connected to the upper end face of the base plate 201a and communicates with the movable cavity 201a-1. The column rod 201e is located inside the vertical cylinder 201d and is slidably connected to the vertical cylinder 201d. The movable cavity 201a-1 is provided with a cam 201b-2 located in the middle of the crossbar 201b. The cam 201b-2 is fixedly connected to the crossbar 201b. One end of the connecting rod 201f is hinged to the bottom of the column rod 201e, and the other end of the connecting rod 201f is hinged to the cam 201b-2.

[0035] The dust scraper component 201 also includes a limiting cylinder 201g, a spring 201h, a circular plate 201i, an annular scraper 201j, an annular groove 201k, and a vertical cylinder 201l. The circular plate 201i is located on the upper side of the base plate 201a. The annular scraper 201j is fixedly connected to the edge of the upper end face of the circular plate 201i and is in contact with the inner circumferential surface of the air pipe 100. The annular grooves 201k are symmetrically opened on the front and back of the upper end face of the circular plate 201i. The limiting cylinder 201g is fixedly connected to the middle of the lower end face of the circular plate 201i. The column rod 201e extends upward to the interior of the vertical cylinder 201l and is slidably connected to the inner circumferential surface of the vertical cylinder 201l. The limiting cylinder 201g is fixedly connected to the upper end face of the base plate 201a. One end of the spring 201h is fixedly connected to the circular plate 201i, and the other end of the spring 201h is fixedly connected to the bottom of the limiting cylinder 201g. The vertical cross-section of the annular scraper 201j is an obtuse-angled triangle.

[0036] The moving part 203 includes pulleys 203a, wire rope 203b, take-up and release rollers 203c, and turntable 203d. There are four pulleys 203a, two of which are fixedly connected to the top of the gas supply pipe 100, and the other two are fixedly connected to the upper surface of the base plate 201a. The first end of the wire rope 203b is fixedly connected to the upper end of the gas supply pipe 100, and the wire rope 203b passes through the four pulleys 203a sequentially from right to left. The take-up and release roller 203c is fixedly connected to the upper surface of the gas supply pipe 100, and the end of the wire rope 203b extends upward to the outside of the gas supply pipe 100 and is wound around the take-up and release roller 203c. The turntable 203d is fixedly connected to the take-up and release roller 203c. The wire rope 203b passes through the circular plate 201i and is slidably connected to the circular plate 201i.

[0037] The two pulleys 203a located on the upper surface of the base plate 201a are symmetrical about the vertical cylinder 201d, and the limiting cylinder 201g located on the upper surface of the base plate 201a is symmetrical about the vertical cylinder 201d.

[0038] In operation, the exhaust gas from combustion is sequentially fed through the inlet pipe 101, the gas delivery pipe 100, and the outlet pipe 102 into the desulfurization tower for desulfurization treatment. The exhaust fan 103 facilitates the transmission of the exhaust gas. Since the length of the gas delivery pipe 100 is significantly longer than that of the inlet pipe 101 and the gas delivery pipe 100, most of the dust adheres to the inner wall of the gas delivery pipe 100. When it is necessary to clean the dust adhering to the inner wall of the gas delivery pipe 100, the turntable 203d is rotated to drive the take-up and undo rollers 203c to rotate. The take-up and undo rollers 203c rotate to wind up the wire rope 203b. With the cooperation of the pulley 203a and the wire rope 203b, the base plate 201a moves upward during the winding process.

[0039] During the upward movement of the base plate 201a, the gear 201b-1 meshes with the tooth 201c-1, causing the gear 201b-1 to rotate as the base plate 201a moves upward. The rotation of the gear 201b-1 drives the crossbar 201b to rotate, which in turn drives the cam 201b-2 to rotate. When the cam 201b-2 rotates, it drives the column rod 201e to move up and down via the connecting rod 201f. After the column rod 201e moves up a certain distance, it lifts the circular plate 201i and moves it upward. When the column rod 201e moves down, the circular plate 201i moves downward relative to the base plate 201a under the action of the spring 201h. Therefore, the circular plate 201i will vibrate in the up and down direction when the base plate 201a moves upward. Since the annular scraper 201j is fixedly connected to the circular plate 201i, the annular scraper 201j will vibrate in the up and down direction during the upward movement. When the annular scraper 201j vibrates in the up and down direction, it scrapes and cleans the dust attached to the inner wall of the air supply pipe 100. Since the annular groove 201k is located outside the bottom plate 201a, most of the scraped dust falls down the inclined surface of the annular scraper 201j into the annular groove 201k and then falls to the bottom of the air supply pipe 100. A small part of the scraped dust falls down the inner wall of the air supply pipe 100 to the bottom of the air supply pipe 100.

[0040] Therefore, when the turntable 203d winds up the wire rope 203b, the annular scraper 201j moves back and forth on the inner wall of the air pipe 100, greatly increasing the cleaning area and making the dust adhering to the inner wall of the air pipe 100 more thoroughly cleaned. Workers can achieve good cleaning results without repeatedly cleaning the inner wall of the air pipe 100, reducing the workload of cleaning the air pipe 100.

[0041] Example 2

[0042] Reference Figure 1-6 This embodiment provides an implementation method for a desulfurization gas transmission pipeline with an anti-clogging structure. Specifically, the flushing component 202 includes a water storage tank 202a, a water cavity 202b, a squeezing cavity 202c, and a flushing nozzle 202d. The water storage tank 202a is fixedly connected to the lower end face of the base plate 201a. The water cavity 202b is opened inside the circular plate 201i. The squeezing cavity 202c is located inside the vertical cylinder 201l and above the column rod 201e. An inlet pipe is connected between the squeezing cavity 202c and the water storage tank 202a. An outlet pipe is connected between the squeezing cavity 202c and the water cavity 202b. Both the inlet and outlet pipes are connected to the top of the squeezing cavity 202c, and a one-way valve is provided inside each pipe. The flushing nozzle 202d is connected to the water cavity 202b and is circumferentially and equidistantly arranged on the lower end face of the circular plate 201i.

[0043] The flushing component 202 also includes a partition 202e and a semi-circular frame 202f. The partition 202e is disposed at the bottom of the gas supply pipe 100, and the semi-circular frame 202f is symmetrical about the partition 202e and movably connected to the bottom of the gas supply pipe 100.

[0044] An arc-shaped groove 201c-2 is provided inside the gas pipe 100 near the long groove 201c. A baffle 201c-3 is slidably connected inside the arc-shaped groove 201c-2. An operating port 201c-4 communicating with the arc-shaped groove 201c-2 is provided on the circumferential surface of the gas pipe 100.

[0045] The water outlet of the flushing nozzle 202d faces the inner circumferential surface of the air supply pipe 100, and the water outlet of the flushing nozzle 202d is designed to be tilted downward at a 45-degree angle.

[0046] In operation, the exhaust gas from combustion is sequentially fed through the inlet pipe 101, the gas delivery pipe 100, and the outlet pipe 102 into the desulfurization tower for desulfurization treatment. The exhaust fan 103 facilitates the transmission of the exhaust gas. Since the length of the gas delivery pipe 100 is significantly longer than that of the inlet pipe 101 and the gas delivery pipe 100, most of the dust adheres to the inner wall of the gas delivery pipe 100. When it is necessary to clean the dust adhering to the inner wall of the gas delivery pipe 100, the turntable 203d is rotated to drive the take-up and undo rollers 203c to rotate. The take-up and undo rollers 203c rotate to wind up the wire rope 203b. With the cooperation of the pulley 203a and the wire rope 203b, the base plate 201a moves upward during the winding process.

[0047] During the upward movement of the base plate 201a, the gear 201b-1 meshes with the tooth 201c-1, causing the gear 201b-1 to rotate as the base plate 201a moves upward. The rotation of the gear 201b-1 drives the crossbar 201b to rotate, which in turn drives the cam 201b-2 to rotate. When the cam 201b-2 rotates, it drives the column rod 201e to move up and down via the connecting rod 201f. After the column rod 201e moves up a certain distance, it lifts the circular plate 201i and moves it upward. When the column rod 201e moves down, the circular plate 201i moves downward relative to the base plate 201a under the action of the spring 201h. Therefore, the circular plate 201i will vibrate in the up and down direction when the base plate 201a moves upward. Since the annular scraper 201j is fixedly connected to the circular plate 201i, the annular scraper 201j will vibrate in the up and down direction during the upward movement. When the annular scraper 201j vibrates in the up and down direction, it scrapes and cleans the dust attached to the inner wall of the air supply pipe 100. Since the annular groove 201k is located outside the bottom plate 201a, most of the scraped dust falls down the inclined surface of the annular scraper 201j into the annular groove 201k and then falls to the bottom of the air supply pipe 100. A small part of the scraped dust falls down the inner wall of the air supply pipe 100 to the bottom of the air supply pipe 100.

[0048] Therefore, when the rotating turntable 203d winds up the wire rope 203b, the annular scraper 201j moves back and forth on the inner wall of the air supply pipe 100, greatly increasing the cleaning area and making the dust adhering to the inner wall of the air supply pipe 100 more thoroughly cleaned. This design allows workers to achieve good cleaning results without repeatedly cleaning the inner wall of the air supply pipe 100, reducing the workload of cleaning the air supply pipe 100.

[0049] Initially, the water tank 202a, water chamber 202b, and squeezing chamber 202c are all filled with clean water. When the column rod 201e moves upward, the squeezing chamber 202c becomes smaller. Under the action of the one-way valve, the clean water in the squeezing chamber 202c enters the water chamber 202b through the water outlet pipe. The increased water volume in the water chamber 202b, under pressure, is sprayed downward through the flushing nozzle 202d onto the inner circumference of the air supply pipe 100, cleaning the newly cleaned inner wall of the air supply pipe 100, washing away any dust that was not scraped off, and further optimizing the cleaning effect of the inner wall of the air supply pipe 100.

[0050] The semi-circular frame 202f at the bottom of the gas transmission pipe 100 is used to collect the scraped dust and the wastewater after rinsing. When the column rod 201e moves down, supported by the spring 201h, the downward movement of the column rod 201e is greater than the downward movement of the circular plate 201i, and the squeezing chamber 202c becomes larger. Under the action of the one-way valve, the squeezing chamber 202c is replenished with clean water from the water storage tank 202a through the water inlet pipe, preparing for the next round of rinsing. The bottom end of the baffle plate 201c-3 is close to the upper side of the gear 201b-1, and the top end of the baffle plate 201c-3 is flush with the top end of the long groove 201c. During the process of conveying waste gas, the baffle plate 201c-3 blocks the long groove 201c, and the baffle plate 201c-3 plays the role of preventing dust from adhering to the teeth 201c-1 inside the long groove 201c. When cleaning is being carried out, the long slot 201c is opened by rotating the baffle 201c-3 through the operating port 201c-4 to prepare for subsequent cleaning.
