Description

Technical Field

[0001] This invention relates to the field of dust collector technology, specifically to a circular bag filter dust collector. Background Technology

[0002] A dust collector or dust removal equipment is a device that separates dust from flue gas. A circular bag dust collector, also known as a filter dust collector, is a dry, high-efficiency dust collector. It is a dust removal device that uses bag filter elements made of woven fiber to capture solid particles in dusty gas. Its working principle is that dust particles are intercepted when they collide with the filter fibers due to inertial force as they wrap around the filter cloth fibers.

[0003] In some dry flue gas treatment processes, circular bag filters are used to provide an attachment carrier for baking soda powder in a mixture of flue gas and baking soda, thereby enabling the adsorption of acidic gases by the baking soda. To ensure that condensation or material caking does not occur at the bottom of the dust collector, the temperature of the mixed gas must usually be controlled within a specific range. However, the inlet structure of traditional circular bag filters makes it difficult to dynamically adjust the inlet swirl angle according to the flue gas flow rate, resulting in insufficient adaptability to operating conditions and affecting system efficiency.

[0046] Working principle:

[0047] In use, the mixed gas enters the device through the inlet volute 101. After the airflow enters the inlet volute 101, it is laterally guided into the device along the guide plate 203 to form a cyclone. Then, the height of the cyclone inlet guide to the filter bag 409 is adjusted along the tilt angle of the guide wing 305. Then the cyclone spirals downward. After the airflow reaches the bottom, it spirals upward and flows back. Then the airflow spirals through the filter bag 409. Large particles of baking soda powder adhere to the surface of the filter bag 409 to form an adsorption layer. When the flue gas passes through, the acidic gas inside is adsorbed by the baking soda adsorption layer. Then the exhaust gas passes through the filter bag 409 and is finally discharged from the exhaust port 106.

[0048] When the temperature is 195 degrees Celsius, the air guide 305 is in an "extended" state with a downward angle of 30 degrees to the horizontal, promoting downward airflow circulation. When the local temperature exceeds 225 degrees Celsius, the air guide 305 automatically retracts to an "tilted" state with an upward angle of 60 degrees to the horizontal, guiding the airflow upward, shortening the airflow dwell time and heat release time, thereby reducing heat accumulation. By dynamically adjusting the internal airflow path, it helps maintain the temperature difference between the top and bottom at about 5 degrees Celsius.

[0049] When adjusting the angle of the guide vane 203, the adjustment motor 208 is started. The adjustment motor 208 drives the drive gear 209 to rotate. The drive gear 209 drives the intermediate gear ring 207. The intermediate gear ring 207 drives multiple synchronous driven gears 206 to rotate synchronously. This causes the synchronous driven gears 206 to drive multiple guide vanes 203 to rotate synchronously through the support shaft 205. At the same time, the guide vanes 203 are linked through the synchronous connecting rod 204, so that the angle of the guide vanes 203 is adjusted simultaneously, thereby realizing the adjustment of the air intake swirl angle.

[0050] During cleaning, the valve of the external connector 402 is opened, and high-pressure gas enters the distribution box 401 through the external connector 402, and is then distributed to each air guide pipe 403. The gas is then sprayed into the filter bag 409 through the high-pressure nozzle 404. The filter bag 409 is backflushed by the high-pressure gas, causing the baking soda powder attached to its surface to fall off. The powder then falls into the interior of the dust storage compartment 502, and some falls onto the surface of the isolation plate 509. When the dust concentration sensor 508 detects too much powder, the conversion motor 506 is started. When the conversion motor 506 is started, it drives the drive shaft 507, causing the isolation plate 509 and the dust outlet 511 to rotate to the corresponding position of the dust concentration sensor 508, causing the powder at that position to fall. As the isolation plate 509 rotates, the scraper 504 will clean the surface of the isolation plate 509.
