SHD type desulfurization wet dust collector

The SHD type desulfurization wet dust collector is a wet and dry integrated desulfurization and dust removal equipment, which includes the lower low dust collection section, the middle spray cylinder, the conditioning system, the uniform air device, the screen mesh overcurrent, water film dust collection, upper dehydration and other devices. The smoke enters the low-pressure pipe section through the upper part of the middle cylinder, and quickly enters the lower space to relax. The vast majority of coarse dust particles are collected and fall into the ash hopper. Small smoke and dust enter the humidification and conditioning system, screen water film capture, and disperse colored substances and water mist from the smoke. Clean gas is discharged into the atmosphere through the outlet of the dust collector. The collected smoke and dust are washed down by the liquid water sprayed in at any time and directly recycled.

Maintenance of SHD type desulfurization wet dust collector:

(1) Regularly inspect and clean the water pump to prevent blockage.

(2) The circulating water tank should be cleaned regularly.

(3) The water seal box of the drainage system should be cleaned in a timely manner to prevent dust accumulation.

(4) The condensate seal of the defogger should be regularly unscrewed and inspected for cleaning.

(5) Regular (3-6 months) inspection and cleaning of all inspection doors and drainage outlets should be carried out.

The characteristics of SHD type desulfurization wet dust collector:

1. Washing type working principle, dust removal and desulfurization, capturing a lot of gas.

The flue gas purifier integrates desulfurization and dust removal, with a spray method and nozzle design. It adopts a fiberglass spiral nozzle made of technology, which sprays dense layers of water mist under high water supply pressure. Dust and gas fully contact the water mist, so the effectiveness of dust removal, desulfurization, nitrogen removal, and carbon black washing is greatly improved compared to other wet dust collectors. Dust removal rate ≥, sulfur dioxide removal rate ≥ 85%, and flue gas Ringmann blackness<level 1.

2. Dehydration board has good dehydration effect. There is a dehydration device and a dehydration plate inside the cylinder. When the mist passes through the dehydration device, it is collided and intercepted to change direction, flowing down the cylinder wall to prevent secondary water entrainment and dehydration.

3. Low resistance, water-saving, energy-saving, and low operating costs.

Smoke is naturally introduced from the lower part of the cylinder, with a large cross-section and low wind speed, resulting in low smoke resistance. The main body resistance is ≤ 900Pa, and the system resistance is ≤ 1200Pa. Due to low resistance, the power consumption is also low. In addition, the discharged water is precipitated and closed for recycling, which not only saves water resources but also prevents sewage from flowing into the sewer, causing secondary pollution, achieving water-saving and energy-saving effects, and reducing operating costs.

4. Small size, light weight, small footprint, convenient installation and transportation.

The SHD type desulfurization wet dust collector has a cylindrical shape and belongs to the overall structure. It comes with a bracket when leaving the factory, making installation and relocation very convenient. It can be installed in various ways such as hanging left and right, overhead laying, etc. according to the size and ground situation of the place, with strong adaptability.

5. The operation is relatively simple and convenient, with less maintenance, easy to operate, manage, and maintain, high operating rate, and suitable for various working environments.

6. Strong adaptability to the fluctuation of SO2 concentration in flue gas, and different desulfurization processes can adapt to different sulfur levels in coal; Desulfurizers can be used in various forms such as lime, alkali, and magnesium oxide, all of which can achieve good desulfurization effects.
