Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and in particular relates to a waste gas treatment structure for a light soda ash calcining furnace. Background Technology

[0002] The exhaust gas treatment structure of the light soda ash calciner is a comprehensive purification system designed for the high-temperature dust-containing and corrosive gases generated during the calcination process. Its core function is to achieve compliant emissions and resource utilization of exhaust gas through multi-stage physical separation and chemical treatment technologies.

[0003] Traditional waste gas treatment devices for light soda ash calcination furnaces typically use activated carbon filters to treat the waste gas. However, because the waste gas contains a large number of dust particles, the activated carbon filter layer is quickly clogged, affecting subsequent waste gas treatment. This requires frequent cleaning of the activated carbon filter layer by staff, thereby reducing the waste gas treatment efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas treatment structure for a light soda ash calcining furnace. By setting up a spray mechanism, specifically, after the waste gas enters the waste gas treatment box, an inclined plate guides the waste gas, causing it to flow upwards in an S-shape, increasing the residence time. The lower annular spray pipe then performs a first spray treatment on the waste gas, and the upper annular spray pipe performs a second spray treatment. This method can improve the dust reduction effect on impurities in the waste gas, significantly reducing particulate matter and thus reducing clogging of the air filter and activated carbon filter layer, extending their service life. This solves the problem of traditional waste gas treatment devices for light soda ash calcining furnaces, which typically use activated carbon filters.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1-5 As shown, this utility model is a waste gas treatment structure for a light soda ash calcining furnace, including a waste gas treatment box 1. An inlet pipe 11 is fixedly connected to the left side of the waste gas treatment box 1, and an exhaust pipe 12 is fixedly connected to the top of the waste gas treatment box 1. An installation socket 13 is inserted into the front of the waste gas treatment box 1, and an air filter element 131 and an activated carbon filter layer 132 are fixedly connected to the back of the installation socket 13. A water tank 14 is provided on the right side of the waste gas treatment box 1. It also includes:

[0028] The spray mechanism 2 is located inside the exhaust gas treatment box 1. The spray mechanism 2 includes two annular spray pipes 21 inside the exhaust gas treatment box 1. Several spray heads 211 are fixedly connected to the bottom of each annular spray pipe 21. A connecting pipe 22 is fixedly connected to the right side of each annular spray pipe 21, and a conveying pipe 23 is fixedly connected to the right side of the connecting pipe 22. Two inclined plates 24 are fixedly connected to the inner wall of the exhaust gas treatment box 1. The inclined plates 24 are inclined; after the exhaust gas enters the exhaust gas treatment box 1, the inclined plates 24 guide the exhaust gas, causing it to flow in an S-shape. As the exhaust gas flows upward, increasing its residence time, the lower annular spray pipe 21 performs a first-stage spray treatment on the exhaust gas, while the upper annular spray pipe 21 performs a second-stage spray treatment. This method improves the dust reduction effect on impurities in the exhaust gas, significantly reducing particulate matter and thus reducing clogging of the air filter element 131 and activated carbon filter layer 132, extending their service life. The two annular spray pipes 21 are respectively positioned above the two inclined plates 24, which guide the exhaust gas to flow in an S-shape.

[0029] The conveying pipe 23 passes through the exhaust gas treatment box 1 and extends to the outside. The annular spray pipe 21, the connecting pipe 22 and the conveying pipe 23 are connected to each other. The top of the water tank 14 is fixedly connected to the water pump 141 and the water inlet pipe 142. The bottom of the conveying pipe 23 is fixedly connected to the water outlet of the water pump 141.

[0030] An opening 15 is provided on the front of the exhaust gas treatment box 1. The mounting socket 13 is adapted to the opening 15. The activated carbon filter layer 132 is placed above the air filter element 131. A sealing ring is provided at the connection between the mounting socket 13 and the exhaust gas treatment box 1.

[0031] A filtration mechanism 3 is installed at the bottom of the exhaust gas treatment box 1. The filtration mechanism 3 includes a filter box 31 installed at the bottom of the exhaust gas treatment box 1, a filter box 32 inserted into the top of the filter box 31, and several filter holes opened at the bottom of the filter box 32. A water pump 33 is fixedly connected to the right side of the filter box 31, and a hose 34 is fixedly connected to the outlet of the water pump 33. The other end of the hose 34 is connected to the water tank 14. Wastewater at the bottom of the exhaust gas treatment box 1 enters the filter box 31 through the drain pipe. The wastewater first enters the filter box 32 for filtration. The filter box 32 intercepts particulate matter, and the filtered water enters the filter box 31. The filtered water is then pumped out by the water pump 33 and transported to the water tank 14 through the hose 34, thereby achieving water circulation and reducing water waste.

[0032] A convex ring 321 is fixedly connected to the top of the filter box 32. The diameter of the convex ring 321 is larger than the diameter of the filter box 31. The convex ring 321 is used to support the filter box 32. The bottom of the inner wall of the exhaust gas treatment box 1 is tapered. A drain pipe is fixedly connected to the center of the bottom of the exhaust gas treatment box 1. The drain pipe corresponds to the filter box 31.

[0033] The air inlet pipe 11 is used to connect to the exhaust gas discharge pipe of the calcining furnace, and the exhaust pipe 12 is used to connect to the negative pressure fan.

[0034] One specific application of this embodiment is:

[0035] In use, the inlet pipe 11 is connected to the exhaust gas pipeline of the calcining furnace to transport the exhaust gas into the exhaust gas treatment box 1. The exhaust pipe 12 is connected to a negative pressure fan to draw the exhaust gas in the exhaust gas treatment box 1 upward. At the same time, the water pump 141 is started to draw water from the water tank 14 into the delivery pipe 23, and then splits into two connecting pipes 22. The water then enters the annular spray pipe 21 and is sprayed out from multiple spray nozzles 211. After the exhaust gas enters the exhaust gas treatment box 1, the inclined plate 24 guides the exhaust gas, causing it to flow upward in an S-shape. The lower annular spray pipe 21 then performs the first spray treatment on the exhaust gas, and the upper annular spray pipe 21 performs the second spray treatment on the exhaust gas. Spraying treatment can improve the dust reduction effect of impurities in exhaust gas and significantly reduce the particulate matter in exhaust gas. The water droplets with attached impurities will fall downward to the bottom of the exhaust gas treatment box 1. The exhaust gas after spraying is then treated again by the air filter 131 and the activated carbon filter layer 132 to adsorb harmful gases. Finally, the treated exhaust gas is discharged from the exhaust pipe 12. The air filter 131 and the activated carbon filter layer 132 are both installed on the mounting socket 13 for easy disassembly and replacement. A sealing ring is set at the connection between the mounting socket 13 and the exhaust gas treatment box 1 to prevent exhaust gas from overflowing. The mounting socket 13 can also be fixed to the exhaust gas treatment box 1 with bolts.

[0036] Wastewater at the bottom of the exhaust gas treatment box 1 enters the filter box 31 through the drain pipe. The wastewater first enters the filter box 32 for filtration, where the filter box 32 intercepts particulate matter. The filtered water then enters the filter box 31 and is pumped out by the second water pump 33. The water is then transported to the water tank 14 through the hose 34, thus achieving water circulation and reducing water waste. When the filter box 32 needs to be cleaned, it can be disassembled by lifting it upwards using the protruding ring 321 on the top of the filter box 32, making it convenient for subsequent cleaning or replacement.
