Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more specifically, to a dust removal device. Background Art

[0002] Waste gas treatment mainly refers to a purification method for industrial waste gases generated in industrial sites, such as dust particles, flue gas, odorous gases, and toxic and harmful gases. Common waste gas treatments include smoke waste gas treatment, dust waste gas treatment, organic waste gas treatment, waste gas odor treatment, acid and alkali waste gas treatment, etc. Most of the existing dust removal equipment are bag dust collectors.

[0003] After searching, the utility model patent with Chinese patent number CN202322066715.4 discloses a dust removal device, including: an air collecting hood, a dust removal chamber, a fan and a spray tower are connected in sequence along the ventilation duct where the dust exhaust gas flows; the dust removal chamber includes a shell, an ash hopper and a support leg detachably connected to the bottom of the shell, and an automatic recoil unit; a bag dust collector is arranged in the shell, and when in use, the dust exhaust gas is sucked into the dust removal chamber along the ventilation duct after being sucked in by the air collecting hood, and the large particles in the dust exhaust gas first fall into the ash hopper under the obstruction of the ash baffle plate, and the dust exhaust gas passes through the ash baffle plate from top to bottom and then rises again, and passes through the bag dust collector under the action of negative pressure, and the dust in the dust exhaust gas is filtered out by the bag, and the exhaust gas continues to enter the fan along the ventilation duct, and is sent to the spray tower by the fan, and the adsorbent corresponding to the harmful gas in the exhaust gas is sprayed out through the nozzle by the water pipe to reduce the content of the harmful gas in the exhaust gas.

[0004] However, when it cleans the dust inside the ash hopper, it needs to stop its dust removal work before cleaning the dust inside the ash hopper. A lot of time will be wasted in the process of cleaning the dust. During this time, the dust generated at the construction site will be scattered into the air and cause environmental pollution, which greatly reduces its dust removal efficiency. In addition, it adsorbs harmful gases in the exhaust gas through the adsorbent sprayed from the nozzle. Since the diluted adsorbent sprayed from the nozzle will be blown to the outside of the spray tower with the airflow, the adsorbent is easy to drift into the surrounding air, which also affects the surrounding environment.

At the same time, the first gear 24 is driven to rotate by the motor 23, and the first gear 24 drives the second gear 25 and the rotating pipe 19 to rotate. The second rotating pipe 19 drives the multiple aeration pipes 21 to rotate. Since the air entering into the multiple aeration pipes 21 has a certain pressure, the air will enter into the adsorbent through the air outlet 22. At the same time, the adsorbent and the air are stirred by the aeration pipe 21, so that the air entering into the adsorbent from the air outlet 22 is fully in contact with the adsorbent, and the harmful gas in the air is fully adsorbed by the adsorbent. The air after the harmful gas is adsorbed is discharged to the inside of the absorption box 26 through the air outlet pipe 13, and is discharged to the outside through the multiple air vents 28 in the absorbent cotton 27, and the moisture and adsorbent contained in the air are absorbed by the absorbent cotton 27.
