Description

Technical Field

[0002] Industrial production processes generate large amounts of dust-laden waste gas, which not only pollutes the environment but also harms the health of operators. Therefore, efficient dust removal equipment is an indispensable key facility in industrial production. The choice of dust removal technology directly affects the waste gas treatment effect, production safety, and environmental benefits. The many limitations of traditional dry dust removal technology are becoming increasingly apparent, making it difficult to meet the dust removal needs of modern industry.

[0003] Traditional dry dust collection equipment has significant shortcomings in practical applications: First, it has low efficiency in capturing ultrafine dust. Taking dry electrostatic precipitators as an example, their charging efficiency for fine particulate matter such as PM2.5 is insufficient, and a large number of fine dust particles can easily escape from the electric field, failing to achieve the ideal dust removal effect. Second, it has poor adaptability to working conditions. When faced with high-temperature, flammable, and explosive industrial fumes, dry dust collection equipment is prone to fire and explosion hazards due to dust accumulation and static electricity generation.

[0026] The following is in conjunction with the appendix Figures 1-9 The present invention will be further described below.

[0027] To address the problems existing in the background technology, this application proposes the following technical solution: a water-washing wet industrial dust collector, including a treatment box 1, an air inlet pipe 7 fixedly connected to the outside of the treatment box 1, one end of the air inlet pipe 7 being bent and extending to the bottom of the treatment box 1, and an exhaust pipe 4 fixedly connected to the top of the treatment box 1; a first partition 12 and a second partition 15 fixedly connected inside the treatment box 1, an air extraction component provided above the first partition 12, the output end of the air extraction component being connected to the exhaust pipe 4, and the input end of the air extraction component extending to the bottom of the first partition 12; multiple sets of baffles 16 fixedly connected between the first partition 12 and the second partition 15, multiple sets of through holes 17 provided in the second partition 15, an inverted V plate 22 fixedly connected inside the treatment box 1, arc-shaped plates 23 fixedly connected to both sides of the inverted V plate 22, and rocker plates 24 fixedly connected to both sides of the bottom of the treatment box 1; and an atomizing spray component provided inside the treatment box 1.

[0028] In this embodiment, the treatment chamber 1 serves as the core dust removal cavity, providing a closed space for waste gas treatment and preventing secondary pollution caused by waste gas leakage. The inlet pipe 7 bends and extends to the bottom of the treatment chamber 1, guiding the waste gas to flow upward from the bottom and form a reverse contact with the atomized water liquid, significantly improving the dust capture probability. The exhaust pipe 4 is located at the top, working in conjunction with the air extraction component to ensure the smooth discharge of purified gas, forming a reasonable airflow channel. The first partition 12 and the second partition 15 divide the treatment chamber 1 into different functional areas, realizing the orderly connection of processes such as dust removal and gas-liquid separation. Multiple sets of baffles 16 can forcibly change the airflow direction, using inertia to separate water droplets from gas, preventing water from being discharged with the purified gas. The guide structure composed of the inverted V-plate 22, the arc-shaped plate 23, and the rocker plate 24 can guide the airflow to form a vortex, expanding the gas-liquid contact area and time, and improving the dust removal effect. The atomizing spray component can convert the water liquid into a fine water mist, enhancing the adsorption capacity for dust particles and solving the problem of secondary dust generation that is easy to occur in traditional dry dust removal.

[0029] In this embodiment, the air extraction component is a fan 11 fixedly connected to the top of the first partition 12. The output end of the fan 11 is fixedly connected to the exhaust pipe 4. The first partition 12 is provided with an exhaust port 25. A fixing cover 14 is fixedly connected to the top of the exhaust port 25. An input pipe 13 is fixedly connected to the input end of the fan 11. The input pipe 13 is fixedly connected to the inside of the fixing cover 14.

[0030] The fan 11, as the core exhaust power component, provides a stable negative pressure environment within the treatment chamber 1, ensuring that exhaust gas continuously and smoothly enters the treatment chamber 1 through the inlet pipe 7, thus guaranteeing the continuity of the dust removal process. The cooperation between the fixed cover 14 and the exhaust port 25 accurately collects the treated gas, preventing gas stagnation or leakage within the treatment chamber 1 and improving gas collection efficiency. The output end of the fan 11 is directly connected to the exhaust pipe 4, shortening the gas discharge path, reducing pressure loss, and ensuring rapid discharge of the purified gas. This integrated exhaust structure design is compact, occupies little space, and facilitates later maintenance. Compared to traditional decentralized exhaust structures, this design effectively improves airflow stability, preventing airflow fluctuations from affecting dust removal and gas-liquid separation effects, and ensuring consistent dust removal efficiency.

[0031] In this embodiment, the atomizing spray assembly includes a fixed pipe 20 fixedly connected to both sides inside the processing box 1 and multiple sets of atomizing nozzles 21 fixedly connected to the fixed pipe 20. A water tank 3 is fixedly connected to the outside of the processing box 1, a water pump 8 is fixedly connected inside the water tank 3, and a water pipe 18 is fixedly connected to the output end of the water pump 8. The water pipe 18 is fixedly connected to the fixed pipe 20.

[0032] The fixed pipe 20 provides a stable mounting base for the atomizing nozzles 21. Multiple atomizing nozzles 21 are distributed on both sides of the treatment tank 1, enabling all-round and uniform spraying of water, ensuring full contact between exhaust gas and water mist, and avoiding dust collection dead zones. The water tank 3 stores water for dust removal, realizing centralized management and recycling of water resources, and reducing water costs. The water pump 8 provides stable power for water delivery, ensuring that the atomizing nozzles 21 can continuously spray water mist with sufficient pressure, guaranteeing stable dust removal effect. The water pipe 18 connects the water pump 8 and the fixed pipe 20, realizing efficient water delivery. The entire atomizing spray assembly has a simple and reliable structure and is easy to operate. The atomizing nozzles 21 convert water into fine water mist, increasing the contact area between water and dust particles, effectively capturing fine dust particles, and solving the problem of low capture efficiency of fine particulate matter in traditional wet dust removal.

[0033] In this embodiment, a first pipe 6 and a second pipe 9 are fixedly connected to the water tank 3. A water pump 8 is fixedly connected to the first pipe 6. An observation window 19 is also fixedly connected to the outside of the water tank 3. A buffer box 2 is fixedly connected to the outside of the treatment box 1. The buffer box 2 communicates with the inside of the treatment box 1. A top cover 5 is detachably connected to the top of the buffer box 2. A third pipe 10 is fixedly connected to the bottom of the treatment box 1. Valves are installed in the first pipe 6, the second pipe 9, and the third pipe 10.

[0034] The system includes three main components: the first pipe 6 provides an inlet for the water pump 8; the second pipe 9 is used for replenishing or replacing water in the water tank 3; and the third pipe 10 facilitates the discharge of wastewater from the treatment tank 1. These three pipes, along with valves, enable flexible water resource management and improve operational convenience. The observation window 19 allows operators to visually monitor the water level in the water tank 3, facilitating timely water replenishment and preventing water shortages from affecting dust removal operations. The buffer tank 2, connected to the treatment tank 1, stabilizes the air pressure within the treatment tank 1, preventing air pressure fluctuations that could lead to exhaust gas leakage or reduced dust removal efficiency. The buffer tank 2 also collects some condensate or impurities, reducing cleaning pressure within the treatment tank 1. The removable top cover 5 facilitates cleaning and maintenance of the buffer tank 2, preventing impurity buildup from affecting equipment operation. The valves precisely control the on / off state and flow rate of each pipe, adapting to different dust removal needs under various operating conditions and enhancing the equipment's versatility and operational safety.

[0035] The usage method of this embodiment is as follows:

[0036] When in use, the exhaust gas to be treated is transported to the air inlet pipe 7 by the blower 11, and the water pump 8 is started at the same time. The water pump 8 draws out the water in the water tank 3 and sprays it out through the atomizing nozzle 21. The atomized water can be sprayed on the exhaust gas containing dust.

[0037] Blower 11 provides stable power for the transport of exhaust gas, ensuring a continuous flow of exhaust gas into treatment chamber 1 and preventing insufficient air intake from affecting dust removal efficiency. Water pump 8 drives water through atomizing nozzles 21 to form a fine mist, increasing the contact area between the water and dust particles, enabling rapid adsorption of dust particles in the exhaust gas and achieving preliminary dust removal. The atomized water sprayed into the exhaust gas effectively suppresses dust re-entrainment, avoiding secondary dust generation problems associated with traditional dry dust removal and protecting the production environment. Simultaneous air intake and spraying ensure continuous exhaust gas treatment without intermittent operation, improving overall dust removal efficiency. The entire start-up process is simple and convenient, requiring only minimal training for operators, and is suitable for the needs of large-scale industrial production.

[0038] The inverted V-plate 22, the arc-shaped plate 23, and the rocker plate 24 form an arc-shaped swirling flow guide structure. This structure guides the dust-laden airflow through the arc-shaped channel, creating a swirling flow that significantly increases the contact time and area between the airflow and the sprayed water mist, allowing dust particles to be more fully adsorbed and captured by the water mist. The centrifugal force generated by the swirling flow throws the dust-laden water droplets carried in the airflow toward the inner wall of the equipment, causing the water droplets to converge and flow back into the storage tank, further reducing the amount of water discharged with the purified gas.

[0039] The arc-shaped swirling flow guide structure directs the dust-laden airflow into a stable swirling flow. Compared to traditional straight airflow, this significantly increases the contact time and area between the airflow and the water mist, ensuring that dust particles are fully adsorbed by the water mist and significantly improving dust removal accuracy. The centrifugal force generated by the swirling flow throws the dust-laden water droplets towards the inner wall of the equipment, achieving preliminary gas-liquid separation and reducing the pressure of subsequent gas-liquid separation. After the water droplets collect, they flow back to the storage tank, enabling partial recycling of water resources, reducing water costs, and minimizing water discharge with the purified gas, thus avoiding impact on subsequent equipment or the environment.

[0040] After the treated exhaust gas passes through the baffle 16, the airflow carrying water droplets passes through the wave-shaped channel between these baffles 16. The airflow is forced to repeatedly change its direction of flow. The water droplets collide with the baffle 16 due to inertia and then converge into a water flow that flows back to the bottom of the treatment box 1, thereby achieving gas-liquid separation and preventing water from being discharged from the equipment with the purified gas.

[0041] The wavy channels between the baffles 16 force the airflow to repeatedly change direction. Utilizing the inertial difference between water droplets and gas, the water droplets collide with the baffles 16, achieving efficient gas-liquid separation. This inertial separation method requires no additional power, has low energy consumption, and provides stable separation. It effectively removes water droplets carried in the airflow, preventing moisture from being discharged with the purified gas and causing corrosion of the exhaust pipe 4 or environmental pollution. The water droplets converge and flow back to the bottom of the treatment tank 1, further realizing water resource recycling and reducing operating costs. The baffles 16 have a simple structure, are not easily clogged, have low maintenance costs, and are suitable for treating dust of different concentrations. This step significantly improves the dryness of the purified gas, ensuring the quality of subsequent emissions or reused gas.

[0042] The treated gas is then extracted by the blower 11 and discharged through the exhaust pipe 4.

[0043] Fan 11 provides stable suction power, enabling it to quickly extract the purified gas after dust removal and gas-liquid separation, preventing gas from stagnating in the treatment chamber 1 and ensuring the continuity of the dust removal process. The purified gas is discharged directly through exhaust pipe 4, with a simple path, reducing the risk of secondary pollution.
