Description

Technical Field

[0001] This utility model relates to the field of dust removal and humidification technology, and in particular to a waste powder emission dust removal and humidification device. Background Technology

[0002] Waste dust emission dust removal and humidification equipment is used to treat waste dust or dust emissions generated during industrial production processes. Its main function is to remove waste dust and control and reduce the emission concentration of dust through humidification technology.

[0003] In industrial production processes, such as cement, metallurgy, and chemical industries, a large amount of waste powder is generated. This waste powder can easily cause dust pollution during the discharge process, harming the environment and human health. However, although traditional dust removal devices can remove some dust, they often suffer from low dust removal efficiency, large equipment size, and high operating costs. In addition, dry dust is more likely to disperse, causing secondary pollution. Therefore, there is an urgent need for a waste powder discharge dust removal and humidification device that is simple in structure, has high dust removal efficiency, low operating costs, and can effectively prevent secondary pollution.

An exhaust port 103 is installed on the side wall of the shell 1 and is connected to the shell 1. An observation window 12 is provided on the side wall of the shell 1 away from the exhaust port 103. The observation window 12 is used to observe the operation inside the shell 1.

[0035] The spraying mechanism includes several atomizing nozzles 2 located at the top of the housing 1.

A water pump 4 is installed at the top of the housing 1. A drain pipe 3 is installed between the atomizing nozzles 2 and the water pump 4, and the drain pipe 3 passes through the top of the housing 1. A water inlet pipe 5 is installed at the end of the water pump 4 away from the drain pipe 3. The water inlet pipe 5 is connected to an external water supply cylinder. In application, the water is atomized into tiny water droplets by the high-pressure atomizing nozzles, which come into full contact with the waste powder, making the dust particles wet and agglomerated, effectively improving the dust removal efficiency. At the same time, the weight of the humidified waste powder increases, making it less likely to disperse and effectively preventing secondary pollution.

[0036] The guide plate 6 is installed inside the housing 1 and located below the waste powder inlet 101. The guide plate 6 is used to guide the waste powder to below the atomizing nozzle 2. The guide plate 6 is inclined and the angle with the horizontal plane is 30-60 degrees.

In application, the control system automatically adjusts the spray volume to achieve automated operation.

[0040] In actual use, waste powder enters the housing 1 through the waste powder inlet 101 and is evenly dispersed below the atomizing nozzle 2 under the guidance of the guide plate 6. The water pump 4 delivers water to the atomizing nozzle 2 through the water inlet pipe 5 and the drain pipe 3. The atomizing nozzle 2 atomizes the water into tiny water droplets, which come into full contact with the waste powder, making the dust particles wet and agglomerate. The humidified waste powder falls into the dust collection bag 8 under the action of gravity. The filtered gas is discharged from the exhaust port 103 through the filter screen 7. The humidity sensor 10 monitors the humidity inside the housing 1 in real time and transmits the signal to the PLC controller 9. The PLC controller 9 adjusts the flow rate of the water pump 4 according to the preset humidity value, thereby controlling the spray volume. The temperature sensor 11 monitors the temperature inside the housing 1 in real time and transmits the signal to the PLC controller 9. The PLC controller 9 adjusts the spray volume according to the temperature change to prevent condensation inside the housing 1.

[0041] This utility model provides a waste powder emission dust removal and humidification device with simple structure, high dust removal efficiency, low operating cost, and effective prevention of secondary pollution.
