Description

Technical Field

[0001] The invention relates to the technical field of combined apparatus for separating particles from gas or steam, in particular to a dust reduction device for engineering construction to prevent air pollution. Background Art

[0002] With the modernization of cities, the construction industry is also developing continuously. During construction, construction machinery will raise a lot of dust, which will affect the health of construction workers and surrounding residents. During the construction process, water is often used to reduce dust. The water absorbs the dust in the air and drops it, achieving rapid dust reduction and facilitating the continuation of construction.

[0003] In the existing dust suppression device, such as Chinese patent application CN117123016A, the air carrying dust on the construction road is sucked into the front side of the inner cavity of the collection chamber through the suction head and the rotating tube mechanism, and the air carrying dust flowing into the front side of the inner cavity of the collection chamber is filtered by the first filter element and then flows out from the front air groove of the collection chamber. At this time, part of the dust flows into the bottom of the inner cavity of the collection chamber and mixes with the water at the bottom of the inner cavity of the collection chamber, and the other part of the dust adheres to the inclined surface on the rear side of the first filter element, and then the convex shaft on the filter mechanism is driven by the hydraulic rod, the first sleeve, the vortex cavity and the driving mechanism to knock the first filter element, so that the dust on the upper surface of the first filter element falls back into the bottom of the inner cavity of the collection chamber and the collection chamber. The water at the bottom of the collecting chamber is mixed, thereby preventing dust from clogging the filter holes of the first filter element and improving the filtration efficiency of the first filter element; then the water mixed with dust at the bottom of the collecting chamber is filtered through the sedimentation mechanism, so that the clean water flows back into the collecting chamber, thereby preventing the viscosity of the water inside the collecting chamber from increasing due to dust, causing dust to float on the surface of the dust and water mixture, and then causing the first filter element to be blocked, thereby solving the problem of existing water spraying dust reduction equipment that the sprayed water carrying dust drops to the ground and evaporates and dries, and the dust will float into the air again and consume a large amount of water resources. At the same time, the problem of water spraying vehicles going back and forth to load water is avoided, thereby improving the dust reduction efficiency and reducing the dust reduction cost.

[0004] However, there are still the following problems: when water is sprayed outward for dust reduction, the effective range is large but the water resources cannot be recycled, the use cost is high, and the use of water resources is relatively wasteful; while spraying dust reduction on the device itself, the water resources can be recycled but the effective range is small, and the treatment efficiency of the device is low.

The barrel 23 generates airflow from the bottom to the top, passes through the inside of the barrel 23 and sprays to the outside of the top of the barrel 23. Water is provided to the water spray ring 25 in the machine body 1, so that the water spray ring 25 sprays water mist outward, thereby performing dust suppression treatment on the environment outside the dust suppression device. At the same time, water is provided to the water spray top arc 32 in the machine body 1, so that the water spray top arc 32 sprays and removes dust in the barrel 23. The water droplets for spraying and removing dust fall into the barrel 23, are filtered, and then flow back to the machine body 1 for reuse. Moreover, the control component box 31 controls the amount of water in the machine body 1 flowing to the water spray ring 25 and the water spray top arc 32, so that when the amount of dust in the environment is large, the amount of water flowing to the water spray ring 25 is controlled to be large, and the amount of water flowing to the water spray top arc 32 is reduced, so that the dust reduction device focuses on the dust reduction treatment in the external environment; when the amount of dust in the environment is small, the amount of water flowing to the water spray top arc 32 is controlled to be large, and the amount of water flowing to the water spray ring 25 is reduced, so that the dust reduction device focuses on the dust reduction treatment in the airflow in the barrel 23, and this part of water is filtered and recovered;

[0056] Furthermore, water first flows from the second hose 29 into the component box 31, and then flows from the component box 31 into the first hose 26 and the third hose 33, and the water in the third hose 33 flows into the water spray top arc 32, so that water is sprayed from the water spray top arc 32 in the form of water droplets for dust reduction treatment, and the first handle 35 is controlled to rotate, and the first handle 35 drives the control plate 34 to rotate, so that the control plate 34 rotates to cover (completely cover or partially cover) the connection between the first hose 26 and the component box 31, or the control plate 34 rotates to cover (completely cover or partially cover) the connection between the third hose 33 and the component box 31, so that the control plate 34 controls the amount of water flowing into the first hose 26 or the third hose 33;

[0057] The water sprayed by the water spray top arc 32 falls into the funnel 36, and the collected water enters the passage control box 37 from the funnel 36, and the collected water enters the filter cartridge 39 from the passage control box 37. The collected water is filtered by the filter cartridge 39 and then flows back to the water tank 27 from the return pipe 310. The second handle 38 is controlled to rotate, and the second handle 38 controls the passage state in the passage control box 37, so that the collected water enters the corresponding filter cartridge 39 from one (or another) passage for filtration, so that the filter cartridge 39 corresponding to the other (or one) passage can be disassembled and replaced.
