Description

Technical Field

[0001] This utility model relates to a dust collector, specifically a modular pumpless self-excited wet dust collector. Background Technology

[0002] Wet scrubbers purify gas by using water to fully contact the dust-laden gas, washing away the dust particles. Wet scrubbers are particularly suitable for handling high-temperature, high-humidity, flammable, and explosive dust-laden gases. They are primarily used to treat dust-laden gases generated in production environments, such as machining dust.

[0003] Traditional wet scrubbers mainly come in two types: spray type and self-excited type. Spray type requires a water pump, which is costly and difficult to maintain; self-excited type does not require a pump, but existing self-excited wet scrubbers have poor dust removal efficiency. Specifically, firstly, the mixing effect of dust-laden gas and water is relatively poor, making it difficult for dust to completely dissolve in the water; secondly, in existing self-excited wet scrubbers, after the dust-laden gas and water are mixed, the gas is directly drawn away by a fan, without completely removing the liquid droplets in the gas. This results in a large number of tiny droplets in the discharged gas, with high humidity, and many dust-laden droplets are discharged with the gas, affecting the dust removal efficiency, potentially shortening the lifespan of the fan, and possibly causing equipment rust and damage in the production environment. In addition, existing self-excited wet scrubbers use a direct upward suction method for both water and dust, which requires high air pressure and is prone to dust leakage, and the mixing effect of water and dust is poor.

[0004] In view of this, this utility model designs a modular pumpless self-excited wet dust collector. Utility Model Content

[0005] The main objective of this disclosure is to provide a modular, pump-free, self-excited wet scrubber to effectively solve the problems raised by the inventors in the aforementioned background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A modular pumpless self-excited wet scrubber includes a lower body, an upper housing, and an air collecting chamber. The upper housing is fixedly installed on the top of the lower body. The air collecting chamber is installed on the rear side of the top of the upper housing, and a casing is installed on the air collecting chamber. A drive mechanism connected to the casing is installed on the top of the upper housing. An overflow box and a water supply pipe assembly are installed on the side of the lower body. Symmetrically arranged blades are installed inside the upper housing. Inspection doors are installed on both the air collecting chamber and the upper housing.

[0007] Preferably, the lower body includes an angle steel frame, a lower cone, an inclined cone channel, and an upper cone. The lower cone is fixedly installed on the angle steel frame, and the side of the lower cone is fixedly connected to the inclined cone channel. A water pump is fixedly installed on the inclined cone channel, and the outlet of the inclined cone channel faces downward. The upper cone is fixedly installed at the lower outlet of the lower cone.

[0008] Preferably, the upper housing includes a housing structure, a guide plate, an upper housing air inlet, and a steel plate. The upper opening of the housing structure is fitted with a steel plate, the guide plate is fixedly installed inside the housing structure, and the upper housing air inlet is fixedly installed on the side of the housing structure. The blades are located below the guide plate, and the housing structure is connected to the lower cone.

[0009] Preferably, a connecting pipe is fixedly installed on one side of the air collecting chamber, and the connecting pipe is fixedly connected to the housing through a sealing plate. A drive shaft is installed inside the housing. The drive mechanism includes a bracket, a motor, a drive wheel, and a belt cover. The motor and the bracket are fixedly installed on the steel plate, and drive wheels are installed on both the output end of the motor and the drive shaft. The two drive wheels are connected by a drive belt, and a belt cover is fitted on the outside of the drive belt. The belt cover is fixedly connected to the bracket.

[0010] Preferably, a connecting pipe is fixedly connected to the side of the overflow box, and the connecting pipe extends into the lower cone. A cone-sealed double 90-degree steel wire braided hose assembly is fixedly connected to the side of the overflow box through a flange and a gasket. The other end of the cone-sealed double 90-degree steel wire braided hose assembly is fixedly connected to the box structure through a flange and a gasket. A flushing water pipe and a valve are fixedly connected to the lower end of the side of the overflow box. Several short pipes and caps are fixedly installed on the other side of the overflow box.

[0011] Preferably, the water supply pipeline assembly includes a water supply pipeline body, a four-way pipe, and a second standard gate valve. The four-way pipe is fixedly installed between the water supply pipeline bodies, and the two ends of the four-way pipe are respectively connected to another water supply pipeline and the second standard gate valve.

The two ends of the water supply pipeline assembly are respectively fixedly connected to the upper and lower ends inside the upper box body, and the blades block the two.

[0012] Preferably, a first standard gate valve is installed at the bottom of the inclined cone channel.

[0013] In view of this, compared with the prior art, the beneficial effects of this utility model are: (i) In this application, after the dust-laden gas enters the equipment, the high-pressure blower forces it into the water tank, and the dust is captured by the inertial collision and mixing of water droplets and particles. The remaining dust particles are captured a second time by spraying water mist. Finally, the separation of dust and gas is achieved through the synergistic effect of water bath and spraying, and the effect is good.

[0014] (ii) In this application, a waterless design is adopted. Through the optimization of the dual grinding chamber structure, the energy consumption is reduced and the dust removal efficiency is improved by using partition separation and inclined plate diversion technology. The modular design makes maintenance more convenient and is suitable for industrial scenarios with high dust concentration and requiring rapid dust reduction, such as grinding workshops and mining operations.

[0015] (iii) In this application, the design significantly reduces energy consumption and electricity consumption. Attached Figure Description
