Acid mist absorber

Acid mist absorberIt is a treatment equipment suitable for various harmful exhaust gases.

The processing flow of acid mist absorber:

In acidic or alkaline acid mist exhaust gas, a new type of stepped ring packing (or spherical multi-faceted hollow packing) is embedded-Liquid contact has a larger specific surface area; When the exhaust gas passes through the distribution plate, the gas is evenly distributed on multiple hollow spheres, with each sphere in point contact and arranged in a row“W”Walk along the route to avoid any deviation, and use a tornado style non blocking nozzle to create a smooth flow1200Spray to improve the efficiency of gas-liquid mixing90-95%By using a counter current absorption solution (neutralizing solution)H2SO4perhapsNaOHAutomatic addition of processing equipment for atomization spray washing to achieve a clean effect, followed by the addition of neutralizing solution to remove harmful gases from exhaust gas. Generally, there is a two-stage spray device, and multiple layers of spray devices can be formed according to different gas concentrations to achieve high purification efficiency.

Precautions for operating the acid mist absorber:

1Only operate under normal conditions of the water pump and fan;

2If the water pump is started after maintenance, pay attention to whether all parts of the water pump are normal for the acid mist absorber;

3The acid mist absorber should be regularly cleaned and filled to prevent an increase in air resistance and a decrease in treatment efficiency. As the filling is prone to blockage by debris and may crystallize during the exhaust gas treatment process, it is necessary to rinse the filling regularly to prevent blockage and replace it regularly; The cleaning and replacement cycle can be determined according to the actual situation. Generally, the cleaning cycle is once a year, and the replacement cycle is3Once a year.

4Regularly open the sedimentation tank sludge discharge valve (about one month) to remove dust and impurities;

5Ensure that the water pump operates with water to prevent damage caused by pump emptying.

Acid mist absorberOperation and maintenance instructions for water pump: Maintenance during operation:

1The inlet pipe is filled with liquid, and the pump is prohibited from operating in a cavitation state.

2Regularly check the motor current value and ensure it does not exceed the rated current of the motor.

3After long-term operation of the pump, if the mechanical wear and tear of the acid mist purification tower increases the noise and vibration of the unit, it should be stopped for inspection. The vulnerable parts can be replaced at times, and the overhaul period of the unit is generally one year.

4Regular maintenance and upkeep of the water pump once a year: disassembly——Check all vulnerable parts and replace them promptly if any damage is found. The motor bearings should be replaced once a year

5The water pump should be maintained annually, and the insulation resistance value of the motor should be greater than2Megaohms. Regularly perform anti-corrosion maintenance on equipment.

Acid mist absorberUse case:

The following is the acid mist absorber installed by Huakang Environmental Protection for the chemical plant. The equipment has been in operation for two years and has achieved many results, with emissions meeting environmental requirements.
