Description

[Technical Field]

[0001] This invention relates to a wet dust collector that uses the Venturi effect for dust collection. [Previous Technology]

[0002] Note that flour mills, grain mills, feed mills, machinery factories, pharmaceutical factories, paper mills, food factories, woodworking factories, fiber factories, grinding factories, and other manufacturing spaces that use different processing methods usually generate a large amount of dust. If this dust is not fully collected and removed, and is allowed to diffuse freely in the air, it will not only harm the health of employees, but also affect the quality of products. In view of this, some companies have developed a dust collection machine structure that draws the exhaust gas containing dust into a filtration device, and uses the filter media or dust collection bags installed in the filtration device to filter out the dust.

[0003] However, since the filter material and the dust collection bag are consumables that need to be replaced or cleaned regularly, the cost of use is high. Frequent shutdowns for replacement or cleaning will also delay working hours. More importantly, the exhaust gas containing the dust is mostly high temperature, and the dust itself is also flammable. Therefore, using this dry dust collector for treatment may cause a fire. Therefore, it is necessary to make further improvements and innovations.

[0004] Therefore, the inventor, in view of this, conceived the idea of ​​creation and designed it based on many years of experience. After extensive discussions, sample testing, and multiple revisions and improvements, the present invention was launched.

[0006] It is known that the filter media and dust collection bags of dust collectors are consumables that need to be replaced or cleaned regularly. Furthermore, using a dry dust collector for this purpose may cause a fire. This is the technical problem that needs to be solved.

[0008] The wet dust collector of the present invention comprises: a main body, a sludge scraper, and a separator, wherein the main body has a first pipe that slopes upwards above the main body, and a discharge port is provided downwards in the first pipe. A settling tank and a water tank are separated inside the main body. The settling tank is connected to the first pipe. At least one overflow port is formed between the settling tank and the water tank. A filter screen is installed on the overflow port. Furthermore, the side of the main body is positioned relative to the settling tank... A water inlet pipe and an overflow pipe are located at the top, and a discharge pipe is located at the bottom. A water level switch is located at the end of the water inlet pipe to control automatic water replenishment and shut-off. A return pipe is located on the side of the main body relative to the water tank. This return pipe is connected to a water pump, allowing water in the water tank to be pumped back through the return pipe for recycling. The sludge scraper has a conveyor belt and a motor. The conveyor belt is installed on the... Within the settling tank and the first pipe, a conveyor belt, driven by a motor, operates continuously. Several scrapers on the conveyor belt scrape up sludge deposited at the bottom of the settling tank and carry it upwards, allowing the sludge to exit the first pipe through the discharge port. A separator is connected to a second pipe with an air inlet. The separator is installed above the settling tank, with one end forming an exhaust port and the other end having a discharge pipe extending into the settling tank. An atomizing device is installed on the second pipe, comprising a first pipe and at least one second pipe. The first pipe connects the second pipe to the return pipe, allowing the second pipe to receive a water supply. The second pipe extends into the second pipe and has several baffles and nozzles. This constitutes the wet scrubber.

[0010] (a) The wet dust collector of the present invention does not require the use of additional consumables such as filter media or dust collection bags. By utilizing the generation of water mist and the Venturi effect, it can achieve a sufficient and significant dust collection effect, giving the wet dust collector the advantage of low operating cost. There is no need to worry about delays in working hours due to frequent shutdowns to replace or clean consumables.

[0011] (ii) The wet dust collector of the present invention utilizes the generation of water mist and the Venturi effect to achieve the effect of wet dust collection. It is relatively safe to use as there is no concern that dust may easily cause fires during the collection process.

[0012] (iii) The wet dust collector of the present invention produces sludge containing moisture after dust collection, so the subsequent cleaning of the sludge can also avoid generating dust. [Simplified Explanation of the Diagram]

[0023] Continuing from Figures 6 to 8, in actual use, water (40) is injected into the sedimentation tank (101) and the water tank (102) through the inlet pipe (13) for storage. When exhaust gas (50) containing dust (51) is sent into the second pipe (31) from the air inlet (311), water (40) can be sprayed onto the baffle (323) through the nozzle (324) to form a water mist. 400), so that the dust (51) can be more easily and fully mixed with the water mist (400). Through the Venturi effect generated by the separator (30), clean air (60) can be separated to form a cyclone and discharged from the exhaust port (301). At the same time, the dust (51) will mix with water (40) to form slurry, which will be discharged into the settling tank through the discharge pipe (302) after the air (60) is separated. In the sedimentation tank (101), sludge (70) deposited at the bottom is scraped up by the scraper (23) and carried upwards by the conveyor belt (21) away from the sedimentation tank (101).
