Description

Technical Field

[0001] The utility model particularly relates to explosive dust water washing treatment equipment. Background Art

[0002] Everyone knows that dust containing large amounts of CO and H₂ is flammable and explosive. Besides these, dust produced by all combustible materials is also highly flammable and explosive, such as flour, coal dust, sawdust, and cotton staple fibers. Even certain metal powders, such as aluminum powder, can be explosive under certain conditions. To address the problem of dust explosions, mechanical processing and manufacturing processes are often equipped with dust removal systems. Existing dust removal systems include a Venturi tube equipped with a water mist sprayer. One end of the Venturi tube is connected to an air duct, which is equipped with an exhaust fan. A dust collection box is mounted on the exhaust fan's end. The end of the air duct leads to the dust collection box and is equipped with several water spray pipes that spray water parallel to the air duct. A water collection tank is installed outside the dust collection box. After the dust passes through the Venturi tube, some of the dust is separated. The dust after preliminary dust removal is then drawn into the dust collection box by the exhaust fan for water spray removal. However, the dust removal efficiency of this dust removal process is not very ideal. Utility Model Content

The sedimentation chamber 2, the cyclone plate tower 3 and the water washing tower 4 are all provided with a mud hopper 6, and all the mud hoppers 6 are connected to an inclined tube sedimentation tank 7.

[0021] Furthermore, a multi-stage filtering device is provided in the water washing tower 4 .

[0022] Furthermore, a first-stage cyclone plate 31 , a second-stage cyclone plate 32 and a first spraying element 33 are arranged at intervals in the cyclone plate tower 3 .

[0023] Furthermore, the multi-stage filtration device includes an environmentally friendly ball filter layer 41 arranged in the water washing tower 4 and a corrugated plate demister 42 arranged above the environmentally friendly ball filter layer 41, and a second spraying member 43 is provided between the environmentally friendly ball filter layer 41 and the corrugated plate demister 42.

[0024] Furthermore, the environmentally friendly ball filter layer 41 is composed of a plurality of multi-faceted hollow balls that are closely adjacent to and stacked on each other.

[0025] Furthermore, two environmentally friendly ball filter layers 41 are provided and are arranged at intervals along the vertical direction in the water washing tower 4 .

[0026] The working principle of this utility model is:

[0027] First, turn on the fan 5, which draws the explosive dust exhaust gas into the venturi tube 1. The venturi tube 1 uses the action of the airflow to settle part of the dust in the exhaust gas. The explosive dust exhaust gas that has undergone preliminary dust removal enters the settling chamber 2. When the explosive dust exhaust gas enters the settling chamber 2, the gas flow rate decreases due to the expansion of the flow cross-sectional area. At this time, the larger dust particles in the explosive dust exhaust gas naturally settle by their own gravity and are separated and stay at the bottom of the settling chamber 2. The other explosive dust exhaust gas will enter the cyclone plate tower 3. This application is in the cyclone A primary cyclone plate 31 and a secondary cyclone plate 32 are vertically spaced apart in the flow plate tower 3. A first spraying member 33 is provided above each of the primary cyclone plate 31 and the secondary cyclone plate 32. The first spraying member 33 sprays water onto the primary cyclone plate 31 and the secondary cyclone plate 32. Due to the structural effect of the cyclone plate, the explosive dust exhaust gas produces a rotational motion and rises. The liquid sprayed by the first spraying member 33 contacts the gas, so that the solid particulate matter in the exhaust gas is mixed in the water to form wastewater that remains at the bottom of the cyclone plate tower 3. The explosive dust exhaust gas after the cyclone plate tower 3 dust removal enters the water washing tower 4. The present application is provided with a multi-stage filtering device in the water washing tower 4. As Example 1, the multi-stage filtering device can be selected to be provided with an environmental protection ball filter layer 41 and a corrugated plate demister 42 in the water washing tower 4. The two are arranged at intervals, and the environmental protection ball filter layer 41 is arranged near the inlet end of the water washing tower 4, and the corrugated plate demister 42 is arranged above the environmental protection ball filter layer 41. That is to say, when the explosive dust exhaust gas enters the water washing tower 4, it will first pass through the environmental protection ball filter layer 41, and then pass through the corrugated plate demister 42. As Example 1 , there are two environmental protection ball filter layers 41, each of which is composed of multiple polyhedral hollow balls that are closely adjacent to and stacked on top of each other. When the exhaust gas enters the water scrubber 4, water is sprayed through the second spray part 43 to form a water mist. The function of the water mist is to adsorb and dissolve the particulate matter and soluble gases in the exhaust gas into the water. The wastewater formed will fall to the bottom of the water scrubber 4. In this application, multiple polyhedral hollow balls that are closely adjacent to and stacked on top of each other are set in the water scrubber 4. When water is sprayed on the polyhedral hollow balls, the polyhedral hollow balls can increase the contact area between the exhaust gas and the water, thereby improving the purification effect of the exhaust gas. The purified exhaust gas passes through the corrugated plate demister 42 for demisting before leaving the water scrubber 4, completing the purification work. Finally, the mud hopper 6 of the sedimentation chamber 2, the mud hopper 6 of the cyclone plate tower 3, and the mud hopper 6 of the water scrubber 4 are opened, and the wastewater will enter the inclined tube sedimentation tank 7 to remove the suspended matter and solid particles in the wastewater, thereby recycling the wastewater.

[0028] The present application connects a venturi tube 1, a sedimentation chamber 2, a cyclone plate tower 3, a water washing tower 4 and a fan 5 in sequence. The sedimentation chamber 2, the cyclone plate tower 3 and the water washing tower 4 are all provided with a mud hopper 6, and all the mud hoppers 6 are commonly connected to an inclined tube sedimentation tank 7. By setting up a multi-stage dust removal process, the dust removal efficiency is effectively improved. In addition, the inclined tube sedimentation tank 7 can also realize the recycling of wastewater.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
