What should be paid attention to in the use of wet dust collector?
Wet dust remover is also what we usually call "water dust removal". It is a device that makes the dusty gas and liquid (generally water) contact closely, uses the inertia collision of water drops and particles or allows the abundant mixing of water and dust and other functions to capture particles or keep them in fixed containers to reach the separation of water and dust. Then the matters needing attention during the operation of wet dust collector are as follows:
1、 The nozzle, sieve plate, blowdown valve and demisting equipment should be cleaned regularly to prevent blockage.
2、 When the dust removal equipment is shut down for overhaul, it is necessary to check the corrosion, damage or blockage of dust remover body, sieve plate, packing layer, plastic ball, nozzle, demisting equipment and water supply pump, and correct the correction and replace the replacement.
3、 If the wet dust removal equipment is out of service for a long time, all parts in the equipment shall be completely cleaned, and the water stored in the dust collector and relevant containers and pipelines shall be emptied and sealed
4、 Before starting the wet dust collector, the water supply should be started first, and then the induced draft fan of the dust removal system should be started; similarly, when the system is shut down, the induced draft fan should be stopped first, and then the water supply should be stopped.
5、 Regularly check the pH value of the washing solution for spraying and washing, and control the pH value between 6-9. If it is beyond the range, it should be discharged to prevent the washing liquid from corroding or blocking the equipment.
6、 A continuous supply of water should be ensured during normal operation. It is necessary to take feasible anti freezing and thermal insulation measures to ensure the normal operation of the equipment.
7、 According to the characteristics and requirements of various types of wet dust collectors, the water supply pressure and water quantity of water supply system or water level in the water tank should be adjusted and controlled to make the dust removal equipment operate under the state.
