Description

Technical Field

[0001] This utility model mainly relates to the field of solid waste treatment technology, specifically to an integrated dust suppression and purification spray device. Background Technology

[0002] During the solid waste recycling and disposal process, a large amount of dust is generated during the loading, unloading, transportation, and stacking of waste. This dust not only pollutes the environment but also harms human health.

[0003] Currently, common dust suppression methods include water spraying and covering for dust control. However, these methods have problems such as limited dust suppression effect and water waste. At the same time, there is a lack of effective purification measures for dust that has already been generated, making it difficult to effectively control the dust concentration in the air. Therefore, a spray device that can integrate dust suppression and purification is needed to improve the environmental quality during the solid waste recycling process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0032] See attached document Figure 1-4 The integrated dust suppression and purification spray device includes a frame 1, a spray system, a purification system, and a control system. The rear end of the frame 1 is equipped with a water tank 2 and a centrifugal fan 3. The water tank 2 is equipped with a water pump 19. The spray system includes multiple spray pipes 4 mounted on the upper end of the frame 1. Multiple spray heads 5 are connected to the lower end of the spray pipes 4. A crossbeam 6 is connected to the upper end of the spray pipes 4. A lead screw linear module 14 and a slide rail 15 are connected to both ends of the crossbeam 6, respectively. The purification system includes multiple air inlets 8 and air outlets 9. The air inlets 8 are equipped with a fan assembly 10, a filter screen 11, an activated carbon adsorption layer 12, and a photocatalytic oxidation component 13. The multiple air outlets 9 are connected to each other through ventilation ducts 17.

[0033] Multiple T-shaped slides 7 are provided on the upper end of the equipment frame 1. Multiple spray pipes 4 slide back and forth along the T-shaped slides 7. The upper surface of the equipment frame 1 has the same number of T-shaped slides 7 as the number of spray pipes 4, which extend along the width of the frame. The slides have a T-shaped cross-section. The spray pipes 4 can slide back and forth along the T-shaped slides 7. The sliding range covers twice the width of the frame. By adjusting the front and back position of the spray pipes 4, the spray coverage range can be adjusted for different working areas to adapt to changes in the height of the garbage pile.

[0034] Multiple spray heads 5 are equidistantly arranged at the lower end of the spray pipe 4 and embedded below the T-shaped slide 7. The spray heads 5 and the spray pipe 4 have a certain tilt angle. The multiple spray heads 5 are arranged in an array with equal spacing, one every 50cm along the axis of the spray pipe 4. They are connected to the lower end of the pipe through threaded joints. The spray head 5 is embedded below the T-shaped slide 7, and its spray direction forms a tilt angle of 15°-30° with the vertical plane. This angle design allows the atomized particles to spread in a fan shape, effectively covering ground dust sources and airborne suspended dust. The spray head 5 integrates an ultrasonic atomization chip, which can convert liquid water into droplets with a particle size of 5-15μm. Combined with the tilted spray angle, it can achieve three-dimensional suppression of dust at different heights.

[0035] The spray pipe 4 is also equipped with a sealing joint 16 at the rear end. The water storage tank 2 is connected to the sealing joint 16 through a connecting hose. The joint adopts a conical sealing surface and an O-ring sealing structure to ensure the sealing of the high-pressure water circuit. The water pump 19 is installed at the outlet of the water storage tank 2 and is connected to the joint through the connecting hose. The water pump 19 pressurizes and adjusts the output pressure to achieve dynamic control of the spray volume.

[0036] The crossbeam 6 is fixedly connected to multiple spray pipes 4 by locking screws, and its two ends are respectively connected to the sliders on the lead screw linear module 14 and the slide rail 15. The crossbeam 6 is fixedly connected to the top of each spray pipe 4 by four sets of locking screws. The left end of the crossbeam 6 is connected to the sliding nut of the lead screw linear module 14 by bolts, and the right end is connected to the slider of the slide rail 15 by transition fit, ensuring low friction and high rigidity when the crossbeam 6 moves. This mechanism can drive the spray pipes 4 to move laterally to achieve full coverage spraying of the work area.

[0037] Air inlet 8 and air outlet 9 run through the front and rear ends of the equipment frame 1. Fan assembly 10, filter screen 11, activated carbon adsorption layer 12 and photocatalytic oxidation component 13 are arranged sequentially inside air inlet 8. The internal components are arranged in the direction of air flow. Filter screen 11 is located behind air inlet 8 and is made of metal wire mesh. It can initially filter larger dust particles in the air, such as particles with a diameter greater than 10 micrometers. Activated carbon adsorption layer 12 is located behind filter screen 11 and is made of granular activated carbon filled in a mesh frame. It uses the adsorption effect of activated carbon to remove harmful gases and smaller dust particles in the air, such as sulfur dioxide and nitrogen oxides. Photocatalytic oxidation device 13 is located behind activated carbon adsorption layer 12. It contains ultraviolet lamp and titanium dioxide photocatalyst. The ultraviolet light emitted by the ultraviolet lamp irradiates the photocatalyst, which can decompose and oxidize organic pollutants and bacteria in the air to generate harmless carbon dioxide and water, further purifying the air.

[0038] The ventilation duct 17 is equipped with a pipe interface 18. The air inlet of the centrifugal fan 3 is connected to the pipe interface 18 through a corrugated pipe. The purified air is discharged through the air outlet 9 and integrated into the ventilation duct 17. After the centrifugal fan 3 is started, it is connected to the pipe interface 18 through the corrugated pipe to discharge the purified air in the ventilation duct 17.

[0039] The sensor types include dust concentration sensors and humidity sensors. The dust concentration sensor 14 is located at the air inlet 8 and uses a laser dust sensor to detect the dust concentration in the air. The humidity sensor 15 is located around the equipment frame 1 to detect the ambient humidity. The equipment is adjusted based on real-time monitoring data. Adjustment items include spray volume, purification intensity, and working time.

[0040] In this embodiment, the working principle is as follows:

[0041] When the device is running, the water pump 19 and the fan assembly 10 of the air inlet 8 work. The water pump 19 draws water from the water storage tank 3 and delivers it to the spray head 7 through the spray pipe 6. The spray head 7 atomizes the water and sprays it into the air to suppress the generation of dust.

[0042] The fan assembly 10 draws in air containing dust from the air inlet 8, filters out larger dust particles through the filter screen 11, then adsorbs harmful gases and smaller dust particles through the activated carbon adsorption layer 12, and finally decomposes and oxidizes organic pollutants and bacteria through the photocatalytic oxidation device 13. The purified air is then discharged from the air outlet 9.

[0043] The control system automatically adjusts the flow rate of the spray head 5 and the working intensity of the photocatalytic oxidation device 13 based on the signals detected by the dust concentration sensor and the humidity sensor, thereby realizing the intelligent operation of the device.

[0044] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
