Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a hazardous waste spraying device. Background Technology

[0002] In the treatment of hazardous waste, such as incineration and landfill pretreatment, waste gases containing large amounts of harmful substances are generated, including acidic gases (hydrogen chloride, sulfur dioxide, etc.), heavy metal vapors, and organic pollutants. Direct discharge of these gases poses a serious threat to the atmospheric environment and human health. Furthermore, for some liquid or solid hazardous wastes, specific treatment processes require neutralization, cleaning, or cooling through spraying.

[0003] Traditional hazardous waste scrubbing devices have many shortcomings. On the one hand, uneven spraying prevents some waste gas or waste from fully contacting and reacting with the scrubbing liquid, resulting in low treatment efficiency. For example, some spray heads are poorly designed, producing spray liquid in columnar or large droplet shapes with limited coverage. This makes it difficult to achieve comprehensive and effective treatment when the waste gas flow rate is large or the waste accumulation is complex. Therefore, this paper studies a hazardous waste scrubbing device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hazardous waste spraying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hazardous waste spraying device includes a housing, an inlet cover plate rotatably connected to the outer wall of one end of the housing, an outlet cover plate rotatably connected to the bottom of the housing, a base provided on the outer wall of the bottom of the housing, a swing processing mechanism provided between the housing and the base, a rotating spraying mechanism provided on the top of the inner wall of the housing, a waste agitation mechanism provided on the bottom of the inner wall of the housing, and a top cover threadedly connected to the top of the housing.

[0007] Preferably, the swing processing mechanism includes a swing motor and a movable plate, the swing motor and the base are fixedly connected, the output end of the swing motor and the movable plate are fixedly connected, and a connecting frame is fixedly connected to the outer wall of the box.

[0008] Preferably, multiple springs and limiting telescopic rods are fixedly connected between the movable plate and the connecting frame, and multiple vibration motors are fixedly connected to the outer wall of the box.

[0009] Preferably, the rotating spray mechanism includes a second motor and a second rotating shaft. A top box is fixedly connected to the top of the top cover. The bottom of the second motor and the second rotating shaft are fixedly connected. The second rotating shaft is hollow and has a through hole on its outer wall, which is located inside the top box. Multiple liquid guide pipes are fixedly connected to the outer wall of the second rotating shaft. Multiple spray heads are fixedly connected to the bottom of the liquid guide pipes. An inlet pipe is fixedly connected to the outer wall of one end of the top box, and an inlet valve is fixedly connected to the outer wall of the inlet pipe.

[0010] Preferably, an air inlet pipe is fixedly connected to the outer wall of one end of the top box, and an air pump is fixedly connected to the outer wall of the air inlet pipe.

[0011] Preferably, the waste agitation mechanism includes a first motor and a first rotating shaft.

[0012] Preferably, the top of the agitator is provided with multiple crushing blades, and the crushing blades are fixedly connected to the outer wall of the second rotating shaft.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The oscillating treatment mechanism uses an oscillating motor to drive the movable plate to oscillate back and forth. Combined with the elastic buffering of springs and limit rods, this generates low-frequency vibration in the container. Simultaneously, a vibrating motor provides high-frequency vibration. The combined effect of these two mechanisms loosens and distributes solid hazardous waste, preventing accumulation dead zones. The second motor of the rotating spray mechanism drives the second rotating shaft to rotate, causing the spray head to form an all-around rotating spray. The spray liquid enters the guide pipe through through-holes and is sprayed out in an atomized form, increasing the coverage area compared to traditional fixed spray heads. This ensures that all surfaces of the hazardous waste are in full contact with the spray liquid, improving reaction efficiency.

[0015] 2. The first motor of the waste agitation mechanism drives the first rotating shaft to rotate, causing the agitator to turn the material over, exposing the bottom layer of waste to the spray area. The solid hazardous waste is then cut and crushed using the crushing blades on the outer wall of the second rotating shaft. An air pump injects air into the top chamber through the air inlet pipe, which then enters the second rotating shaft through the through-hole and is sprayed out from the spray head, forming a gas-liquid mixture. This improves the penetration of the spray liquid and creates turbulence in the liquid waste, enhancing the mass transfer effect. Attached Figure Description

Simultaneously, a vibration motor 3 provides high-frequency vibration. The combined effect of these two mechanisms loosens and distributes solid hazardous waste, preventing accumulation dead zones. A second motor 19 of the rotating spraying mechanism drives a second rotating shaft 15 to rotate, causing the spray head 18 to form an all-around rotating spray. The spray liquid enters the liquid guide pipe 16 through a through hole 23 and is sprayed out in an atomized form, increasing the coverage area compared to traditional fixed spray heads. This ensures that all surfaces of the hazardous waste are in full contact with the spray liquid, improving reaction efficiency.

The two work together to loosely distribute solid hazardous waste and avoid dead corners of accumulation.

[0024] The rotating spray mechanism includes a second motor 19 and a second rotating shaft 15. A top box 21 is fixedly connected to the top of the top cover 17.

An inlet pipe 25 is fixedly connected to the outer wall of one end of the top box 21. An inlet valve 24 is fixedly connected to the outer wall of the inlet pipe 25. The second motor 19 of the rotating spray mechanism drives the second rotating shaft 15 to rotate, so that the spray heads 18 form an all-round rotating spray. The spray liquid enters the liquid guide pipe 16 through the through hole 23 and is sprayed out in an atomized form.

The first rotating shaft 13 is fixedly connected to the first motor 12. The first motor 12 is fixedly connected to the housing 1. Multiple agitating plates 11 are fixedly connected to the outer wall of the first rotating shaft 13. The first motor 12 of the waste agitation mechanism drives the first rotating shaft 13 to rotate, which drives the agitating plates 11 to turn the material over so that the bottom waste is exposed to the spraying area.

[0027] The top of the first rotating shaft 13 is provided with multiple crushing blades 14. The crushing blades 14 are fixedly connected to the outer wall of the second rotating shaft 15. The crushing blades 14 on the outer wall of the second rotating shaft cut and crush solid hazardous waste.

The second motor 19 drives the second rotating shaft 15 to rotate, and the crushing blade 14 crushes large pieces of waste. The first motor 12 drives the stirring plate 11 on the outer wall of the first rotating shaft 13 to turn the material.
