Description

Technical Field

[0001] This utility model relates to the field of sodium butyrate recovery technology, specifically to a sodium butyrate dust recovery device. Background Technology

[0002] Sodium butyrate, as an important chemical product and feed additive, easily generates a large amount of dust during its production, processing, and packaging. This dust not only wastes raw materials and results in economic losses, but also poses an explosion risk, seriously threatening the production environment and the health of operators. Therefore, the efficient recovery and treatment of sodium butyrate dust is of significant economic and safety importance.

[0003] Currently, most common dust recovery devices use a single filtration unit, such as a single-stage filter cartridge for dust collection. While this structure is simple, the filter cartridge is prone to rapid clogging when handling high concentrations of fine-particle sodium butyrate dust. This leads to a sharp increase in system resistance, a decrease in filtration efficiency, and frequent shutdowns for cleaning or filter cartridge replacement, severely impacting the continuity and stability of production.

[0004] Therefore, we propose a sodium butyrate dust recovery device. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-4 As shown, a sodium butyrate dust recovery device mainly includes a purification box 1, an exhaust gas inlet 2, an air pump 3, a maintenance plate 4, a backflushing cleaning structure 5, and support legs 6.

[0025] The purification chamber 1 is the main body of the device. An exhaust gas inlet 2 is installed in the middle of its left outer surface for connecting to an external dust-laden gas pipeline to introduce the sodium butyrate dust gas to be treated. Support legs 6 are fixedly installed at the four corners of the bottom of the purification chamber 1 to support and secure the entire device. A maintenance plate 4 is bolted to the bottom of the front outer surface of the purification chamber 1. A ring-shaped rubber seal is provided on the contact surface between the maintenance plate 4 and the chamber body to ensure sealing and prevent dust leakage. Opening the maintenance plate 4 allows for cleaning of the dust accumulated inside the chamber.

[0026] The interior of the purification chamber 1 is divided into two chambers, left and right, by a vertical partition 7. A horizontal partition 8 is fixedly installed on the upper left side of the vertical partition 7, and a large-pore filter element 10 is bolted to the lower part of the horizontal partition 8. A small-pore filter element 11 is bolted to the upper right side of the inner chamber of the purification chamber 1. The filter cartridge 12 of the large-pore filter element 10 has a pore size of 5-10 micrometers and is used for primary filtration to intercept larger dust particles; the filter cartridge 12 of the small-pore filter element 11 has a pore size of 1-3 micrometers and is used for fine filtration to capture fine dust particles.

[0027] Both the large-pore filter element 10 and the small-pore filter element 11 include a filter cartridge 12, a connecting flange 13, and a sealing plate 14. The connecting flange 13 is fixed to the upper outer wall of the filter cartridge 12 for connection and fixation. The sealing plate 14 is fixed to the bottom of the inner cavity of the filter cartridge 12, and a through hole 15 is opened in the middle of the sealing plate 14. An arc-shaped air guide pipe 9 is fixedly installed between the middle of the transverse partition 8 and the upper part of the vertical partition 7. One end of the arc-shaped air guide pipe 9 passes through the transverse partition 8 and communicates with the upper part of the inner cavity of the filter cartridge 12 of the large-pore filter element 10, and the other end passes through the vertical partition 7 and extends to the upper part of the right side chamber, for guiding the gas after primary filtration to the area of ​​the small-pore filter element 11.

[0028] An air pump 3 is fixedly installed on the right side of the upper outer surface of the purification box 1. The air pump 3's air extraction pipe passes through the upper part of the filter cartridge 12 of the small-diameter filter element 11. By extracting air, a negative pressure is formed, driving the gas flow and discharging the finally purified gas.

[0029] A backflush cleaning structure 5 is installed on the lower left side of the purification chamber 1, including a backflush main pipe 16, a first backflush branch pipe 17, and a second backflush branch pipe 18. The backflush main pipe 16 is located at the bottom of the inner cavity of the purification chamber 1 and passes through the lower part of the vertical partition 7. Its left end passes through the shell of the purification chamber 1 and connects to an external high-pressure air source. The first backflush branch pipe 17 and the second backflush branch pipe 18 are both vertically fixed to the upper end of the backflush main pipe 16. The upper end of the first backflush branch pipe 17 extends into the filter cartridge 12 of the large-pore filter element 10, and the second backflush branch pipe 18 extends into the filter cartridge 12 of the small-pore filter element 11. Backflush nozzles 19 are evenly distributed on the upper outer wall of the first backflush branch pipe 17 and the second backflush branch pipe 18, located inside their respective filter cartridges 12. The external high-pressure air source is activated at regular intervals. The backflushing gas is transported through the backflushing main pipe 16 and branch pipes, and finally sprayed out by the backflushing nozzle 19 to blow back the inner wall of the filter cartridge 12, causing the attached dust to fall off and achieving automatic dust removal.

[0030] The working principle of this invention is as follows: Sodium butyrate gas containing dust enters the left chamber of the purification chamber 1 through the exhaust gas inlet 2. It first undergoes primary filtration through the large-pore filter element 10, where larger particles are trapped. The preliminarily purified gas then enters the right chamber through the arc-shaped air guide pipe 9, where it undergoes secondary fine filtration through the small-pore filter element 11, capturing fine dust particles. Finally, the clean gas is drawn out by the suction pump 3. During operation, the backflushing cleaning structure 5 is activated intermittently at regular intervals. High-pressure gas is used to backflush and clean the two filter elements through the backflushing nozzles 19. The detached dust falls to the bottom of the purification chamber 1, and can be cleaned periodically by opening the maintenance plate 4.
