Description

Technical Field

[0001] This invention relates to the field of air intake structure technology, specifically to an air intake and cleaning method for desulfurization using a vortex-type pressure-stabilizing guide airflow, and the vortex-type pressure-stabilizing guide air intake structure used therein. Background Technology

[0002] Currently, sulfur- and nitrate-containing gases are usually stored in gas storage tanks. Through the air intake structure, the gas can flow from the gas storage tank into the desulfurization and denitrification device for desulfurization and denitrification treatment. The air intake structure usually uses a fan to draw in the gas.

[0003] The specification of the prior art (publication number CN113464837A) for an auxiliary air intake structure and method with vortex-type pressure stabilizing flow for desulfurization and denitrification mentions that "a driving component is fixedly installed on the top surface of the output end of the air intake pipe, and a vortex flow guide component is provided in the inner cavity of the air intake pipe. When the driving motor is started, the output shaft drives the telescopic driving column to rotate, the third limit block drives the lower gear to rotate, and the lower gear drives the spiral flow guide column and the suction fan to rotate. The gas in the gas storage tank is sucked into the spiral flow guide column by the suction fan, and the gas is continuously transported to the output end of the air intake pipe through the spiral flow guide column." However, in the prior art, the spiral flow guide column guides the gas through a spiral flow guide, and the guide track is constantly rotating forward. The guide trajectory is long, the gas delivery is slow, and it is not easy to clean or replace the inside of the guide pipe, which is not efficient and practical. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a vortex-type pressure-stabilizing and flow-guiding air intake structure for desulfurization is provided to solve the problems of existing technologies where the spiral guide column guides the gas through a spiral guide leaf, the guide track is constantly swirling forward, the guide trajectory is long, the gas delivery is slow, and it is not easy to clean or replace the inside of the guide pipe, making it inefficient and impractical.

[0005] A desulfurization vortex-type pressure-stabilizing guide gas intake and cleaning method involves drawing gas into the guide pipe (1) through the inlet pipe (14). After stable flow through the front vortex pump (25) and the rear vortex pump (21) in the guide pipe (1), the gas is conveniently transported out through the outlet pipe (11). The front vortex pump (25) on the rotating shaft (20) in the guide pipe (1) is located below the inlet pipe (14), which facilitates the rapid introduction of gas from the inlet pipe (14). At the same time, the rear vortex pump (21) on the rear of the rotating shaft (20) is located below the outlet pipe (11), which allows the gas in the rear of the guide pipe (1) to quickly enter the outlet pipe (11). The inlet and outlet of the exhaust gas are accelerated, which helps to improve the overall exhaust efficiency. At the same time, the front scraper (27) and the rear scraper (26) are used to easily scrape off the deposits that have accumulated on the inner wall of the guide pipe 1 over a long period of time.

[0006] A vortex-type pressure-stabilizing and flow-guiding air intake structure used in the above method includes a flow-guiding pipe, a motor, and a rear cover plate. The front end of the flow-guiding pipe is provided with a front connector, and the front connector is screwed onto the front cover plate by threads. The rear end of the flow-guiding pipe is provided with a rear connector, and the rear connector is screwed onto the rear cover plate by threads. The motor is installed in the middle of the rear side of the rear cover plate, and a rotating shaft is installed at the front end of the motor. A front vortex pump is installed at the front of the rotating shaft, and a rear vortex pump is installed at the rear of the rotating shaft.

[0007] Furthermore, an inlet pipe is provided on the upper front side of the guide pipe, and a second external connector is provided at the upper end of the inlet pipe. An outlet pipe is provided on the upper rear side of the guide pipe, and a first external connector is provided at the upper end of the outlet pipe.

[0008] Furthermore, a bushing is provided at the center of the front cover plate, and the front end of the rotating shaft is rotatably connected inside the bushing. The rotating shaft is detachably connected to the front cover plate, the guide pipe is detachably connected to the front cover plate, and the guide pipe is detachably connected to the rear cover plate.

[0009] Furthermore, the lower part of the flow guide pipe is located inside the base, and support frames are provided at both the front and rear ends of the base, and feet are provided on both the front and rear sides of the lower part of the base.

[0010] Furthermore, front scrapers are provided on both the upper and lower front sides of the rotating shaft, and rear scrapers are provided on both the upper and lower rear sides of the rotating shaft, and both the rear scrapers and the front scrapers are in contact with the inner wall of the guide pipe.

[0011] Furthermore, a filter screen is fitted in the middle of the rotating shaft, and a front guide bucket is provided on the front side of the filter screen, and a rear guide bucket is provided on the rear side of the filter screen.

[0012] The beneficial effects of this invention are as follows: 1. This invention draws gas into the guide pipe through the inlet pipe, and after being stably guided by the front and rear vortex pumps in the guide pipe, the gas is conveniently transported out through the outlet pipe, making the gas guidance faster and more convenient.

[0013] 2. The front and rear cover plates installed at both ends of the diversion pipe in this invention are easy to assemble or quick to disassemble, making it convenient to open for inspection or replacement of internal parts, which is more convenient and saves time.

[0014] 3. The front vortex pump on the rotating shaft inside the guide pipe of this invention is located below the inlet pipe, which facilitates the rapid introduction of gas from the inlet pipe. At the same time, the rear vortex pump on the rear of the rotating shaft is located below the outlet pipe, so as to quickly introduce the gas in the rear of the guide pipe into the outlet pipe. The exhaust inlet and outlet are focused on accelerating the flow, which helps to improve the overall exhaust efficiency. At the same time, the front scraper and the rear scraper are used to easily scrape off the adhering substances that have accumulated on the inner wall of the guide pipe over time, which is more convenient for real-time cleaning.

[0015] This invention effectively solves the problems of existing spiral guide columns, where the spiral guide blades guide gas, resulting in a long guide trajectory, slow gas delivery, and difficulty in cleaning or replacing the inside of the guide pipe, making it inefficient and impractical. This invention allows for the convenient installation of a vortex pump below the inlet and outlet of the gas guide pipe, which not only enables rapid gas diversion and reduces the length of the vortex trajectory, but also facilitates simultaneous ash scraping and easy disassembly for inspection or replacement, making it more convenient and practical.
