Description

Technical Field

[0001] This utility model relates to the technical field of cleaning salt mud and scale from spray towers, and in particular to an environmentally friendly device for cleaning salt mud and scale from exhaust gas spray towers. Background Technology

[0002] Over long-term operation, spray towers accumulate salt mud and scale. Excessive scale significantly reduces the efficiency of capturing pollutants from exhaust gases, affecting their normal operation. Therefore, regular maintenance and cleaning are crucial.

[0003] Existing technologies for cleaning salt mud and scale from spray towers, such as the prior art with application number CN202223299249.6, include a spray tower, a drain pipe, a supply pipe, a filter screen, a spray pipe, an atomizing nozzle, an anti-clogging mechanism, a stirring shaft, a connecting frame, a scraper, and a fan blade. By setting up an anti-clogging mechanism, the supply pipe provides high-pressure spray liquid to the spray pipe. As the spray liquid is sprayed out by the atomizing nozzle, the high-pressure spray liquid flows in the supply pipe, driving the fan blade to rotate. The rotation of the fan blade drives the stirring shaft to rotate, and the stirring shaft drives the connecting frame to rotate, which in turn drives the scraper to rotate, allowing the scraper to scrape and clean the inner wall of the spray tower.

[0004] However, when cleaning salt mud from a current spray tower, it is necessary to open the maintenance access port of the spray tower, use a high-pressure water gun to flush the inside of the spray tower to dilute the accumulated salt mud, and then use a pneumatic diaphragm pump to pump the diluted salt mud into a square bucket for further processing. This operation is labor-intensive, produces a strong odor, and consumes a lot of water. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly device for cleaning salt mud and scale from exhaust gas spray towers, which reduces the inhalation of odors, reduces labor intensity and improves labor efficiency, separates salt mud from brine, makes full use of brine, and saves water resources.

[0006] This utility model discloses an environmentally friendly device for cleaning salt mud and sludge from a tail gas spray tower. It includes a tail gas treatment mechanism, a filtration mechanism, a negative pressure mechanism, a collection mechanism, and a flushing mechanism. The filtration mechanism is connected to the tail gas treatment mechanism, the negative pressure mechanism is installed on the filtration mechanism, the collection mechanism is connected to the filtration mechanism, one end of the flushing mechanism is connected to the collection mechanism, and the other end of the flushing mechanism is connected to the tail gas treatment mechanism. The tail gas treatment mechanism treats the tail gas, the negative pressure mechanism creates negative pressure within the filtration mechanism to filter the salt mud, the collection mechanism collects brine, and the flushing mechanism adds the brine from the collection mechanism to the tail gas treatment mechanism. The tail gas treatment mechanism also facilitates the transport of accumulated salt mud to the filtration mechanism for further filtration. The negative pressure mechanism creates negative pressure within the filtration mechanism to filter the salt mud, the collection mechanism collects brine, and the flushing mechanism adds the brine from the collection mechanism to the tail gas treatment mechanism for further flushing of the salt mud within the tail gas treatment mechanism.

[0007] Preferably, the exhaust gas treatment mechanism includes a spray absorption tower and a first pipeline. The first pipeline is installed on the side wall at the bottom of the spray absorption tower, and the other end of the first pipeline is connected to the filtration mechanism. A first valve is installed on the first pipeline. The exhaust gas is treated by the spray absorption tower, and the salt mud in the spray absorption tower is transported to the filtration mechanism for filtration through the first pipeline.

[0008] Preferably, the filtration mechanism includes a filter press and a filter cloth. The filter cloth is installed inside the filter press, and the other end of the first pipeline is connected to the filter press. By opening the negative pressure mechanism, negative pressure is drawn into the filter press, thereby creating a negative pressure inside the filter press. The mixture of salt mud and sludge in the spray absorption tower enters the filter press through the first pipeline and is filtered by the filter cloth to separate the salt mud and sludge from the brine. The salt mud remains in the filter press, and the brine enters the collection mechanism.

[0009] Preferably, the negative pressure mechanism includes a vacuum pump and a connecting pipe. The vacuum pump is connected to the filter press through the connecting pipe. By turning on the vacuum pump, negative pressure is drawn into the filter press, thereby creating negative pressure inside the filter press. The mixture of salt mud and sludge in the spray absorption tower enters the filter press through the first pipeline. The mixture is filtered through the filter cloth to separate the salt mud and sludge from the brine. The salt mud remains in the filter press, while the brine enters the collection mechanism.

[0010] Preferably, the collection mechanism includes a drain pipe and a square bucket. One end of the drain pipe is installed on the filter press, and the square bucket is located at the other end of the drain pipe. A second valve is provided on the drain pipe. By opening the second valve, the brine filtered in the filter press is added to the square bucket through the drain pipe for storage.

[0011] Preferably, the flushing mechanism includes a water pumping pipe, a pneumatic diaphragm pump, and a circulation pipe. One end of the water pumping pipe is located inside the square barrel, and the other end of the water pumping pipe is connected to the pneumatic diaphragm pump. One end of the circulation pipe is installed on the pneumatic diaphragm pump, and the other end of the circulation pipe is installed on the spray absorption tower. By turning on the pneumatic diaphragm pump, the brine in 14 is pumped into the spray absorption tower through the circulation pipe, thereby flushing the salt mud and dirt in the spray absorption tower and improving the cleaning quality.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the exhaust gas is treated by the exhaust gas treatment mechanism, and the salt mud accumulated in the exhaust gas treatment mechanism is easily transported to the filtration mechanism for filtration treatment. The negative pressure mechanism draws negative pressure into the filtration mechanism, so that negative pressure is generated in the filtration mechanism, and the salt mud is filtered through the filtration mechanism. The brine is collected by the collection mechanism, and the rinsing mechanism adds the brine in the collection mechanism to the exhaust gas treatment mechanism, thereby continuing to rinse the salt mud in the exhaust gas treatment mechanism.
