Description

Technical Field

[0001] This utility model relates to the field of waste gas scrubbing technology for stenters, and more particularly to a waste gas scrubbing device for stenters. Background Technology

[0002] In the textile printing and dyeing industry, setting machines are key equipment used for setting fabrics. During operation, they generate a large amount of high-temperature waste gas containing fibers, dyes, volatile auxiliaries, and other components. If this waste gas is directly released into the air, it will not only cause serious environmental pollution and endanger the health of operators and nearby residents, but may also pose safety hazards due to its high temperature.

[0003] Currently, during long-term production and processing in stenters, a large amount of grease, dust, and lint accumulate in the exhaust duct. Cleaning and maintenance are inconvenient and require a lot of working time, affecting the efficiency of the equipment. Furthermore, the temperature inside the exhaust duct is high after long-term operation, and the frequency of static electricity generation is high, which can easily lead to fire hazards and make it difficult to achieve safe production. Therefore, a stenter exhaust gas scrubbing device has been proposed. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste gas scrubbing device for stenters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stenter exhaust gas scrubbing device includes a stenter exhaust duct, a large circulating water tank is provided on one side of the stenter exhaust duct, an automatic water replenishment pipe is connected to one end of the large circulating water tank, a sewage discharge pipe is connected to the other end of the large circulating water tank, a high-pressure water pump is also installed on the outside of the large circulating water tank, and a spray pipe is also provided on the stenter exhaust duct, with the high-pressure water pump connected to one side of the spray pipe.

[0006] Preferably, a filter screen is provided on one side of the large circulating water tank, and a water pipe is connected between the exhaust duct of the stenter and the water inlet of the filter screen, and the water pipe is unidirectional.

[0007] Preferably, the automatic water replenishment pipe is unidirectionally connected to a large circulating water tank, and the large circulating water tank is also provided with an overflow outlet. The outlet pipe of the overflow outlet is connected to a sewage discharge pipe, and a first discharge valve is installed on the sewage discharge pipe.

[0008] Preferably, the spray pipe is connected to multiple spray heads, which are spaced apart in the exhaust duct of the stenter, and the spray heads are atomizing nozzles.

[0009] Preferably, the large circulating water tank, the high-pressure water pump, and the spray pipe are connected in a unidirectional pipeline.

[0010] The beneficial effects of this utility model are: This solution utilizes spray pipes to perform long-term cleaning of the stenter's exhaust duct, preventing impurities such as lint and dust from adhering to the duct. Water pipes facilitate the collection and recycling of the cleaning liquid, while filters remove impurities from the collected circulating water. A high-pressure water pump then re-injects the liquid into the spray pipes for cleaning. During the cleaning process, the liquid continuously cools the duct, preventing fire hazards.

[0011] This solution reduces the accumulation of impurities such as lint and dust inside the air ducts during production and processing, lowers the overall temperature inside the air ducts during production, improves the effectiveness of the device in thoroughly cleaning the air ducts without dead angles, reduces the generation of static electricity, and also improves the overall cleaning and maintenance effect inside the device, greatly improving the overall working efficiency and production safety of the equipment, and truly achieving the effect of safe production.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example: Refer to Figure 1 The stenter exhaust gas scrubbing device includes a stenter exhaust duct 1, a large circulating water tank 5 is installed on one side of the stenter exhaust duct 1, an automatic water replenishment pipe 7 is connected to one end of the large circulating water tank 5, a sewage discharge pipe 8 is connected to the other end of the large circulating water tank 5, a high-pressure water pump 4 is also installed on the outside of the large circulating water tank 5, and a spray pipe 3 is also installed on the stenter exhaust duct 1, with the high-pressure water pump 4 connected to one side of the spray pipe 3.

[0016] Specifically, a filter screen 6 is installed on one side of the large circulating water tank 5 to filter the liquid collected in the stenter exhaust duct 1 to remove impurities for easy recycling. A water pipe 2 is connected between the stenter exhaust duct 1 and the water inlet of the filter screen 6, and the water pipe 2 is unidirectional.

[0017] Furthermore, the automatic water replenishment pipe 7 is unidirectionally connected to the large circulating water tank 5 to replenish water lost due to water level loss. The large circulating water tank 5 is also equipped with an overflow port 9 to discharge liquid after the water level in the large circulating water tank 5 is full. The outlet pipe of the overflow port 9 is connected to the sewage discharge pipe 8, and the sewage discharge pipe 8 is equipped with a first discharge valve.

[0018] In this embodiment, multiple spray heads are connected to the spray pipe 3. The spray heads are spaced apart in the exhaust duct 1 of the stenter. The spray heads are atomizing nozzles, which can make the liquid and gas more fully contact each other and achieve a higher dust removal rate. The large circulating water tank 5, the high-pressure water pump 4 and the spray pipe 3 are connected in a unidirectional pipeline to facilitate the injection of liquid into the spray pipe 3 under high pressure.

[0019] Working principle: The high-pressure water pump 4 is started to input liquid into the spray pipe 3. At this time, the spray head will spray liquid in the exhaust duct 1 of the stenter. The liquid will come into contact with the exhaust gas in the exhaust duct 1 of the stenter. Impurities in the exhaust gas will remain in the liquid. The liquid flows into the large circulating water tank 5 through the water pipe 2. During the flow, the remaining impurities will be filtered by the filter screen 6. The filtered liquid flows back into the large circulating water tank 5. The high-pressure water pump 4 will input the liquid into the spray pipe 3 again to form a circulation. The liquid stored in the large circulating water tank 5 will undergo natural sedimentation. The impurities at the bottom will be discharged through the sewage discharge pipe 8. During the liquid circulation process within the device, the liquid will naturally be lost. Over time, the liquid level in the large circulating water tank 5 will drop. When it drops to a certain height, the automatic water replenishment pipe 7 will automatically replenish the water level. When the replenished water level is too high, the overflow port 9 will open and discharge the excess water through the sewage discharge pipe 8.
