Spray paint exhaust gas treatment manufacturer

Complete set of spray painting exhaust gas treatment equipmentWorking Principle:

The spraying workshop generates a large amount of paint mist during spraying, which can be effectively absorbed into the water using water film circulating water. Due to the solubility of paint mist in water, as the amount of spray paint increases, the content of paint residue in the circulating water also increases. At this point, it is necessary to add paint mist coagulant to the paint wastewater. The paint mist coagulant can effectively suspend the paint residue, and the recycled water after salvage can continue to be used.
Paint mist coagulant can effectively remove the stickiness of paint (paint residue) in the circulating water of water curtains (curtains) spray rooms, causing paint residue to float up. Make the circulating water clear, transparent, and odorless, and can be used for a long time without frequent water changes. It can significantly reduce the COD content in water and greatly reduce the cost of wastewater treatment. Paint residue is not sticky and can be treated as general waste without causing secondary pollution, with low transportation costs. Non corrosive, pipelines and systems will not be blocked, which can extend the service life of equipment (pipelines, water pumps, exhaust fans) and save replacement and maintenance costs. It can improve the quality of spray painting (especially for automotive spray painting) and reduce the rate of repainting, thereby increasing production and efficiency. Maintaining fresh air and balanced air pressure in the spray booth can reduce the occurrence of work safety incidents and improve productivity.

Complete set of spray painting exhaust gas treatment equipmentOperation steps:

1. Preparation before startup:

① Check the liquid level in the circulation tank, replenish immediately when the liquid level is below the mark, and adjust the concentration of the circulation liquid at the same time;

2. Startup steps:

① Turn on the power control system;

② Turn on the circulating pump, and after about 60 seconds, the fan will start;

3. Normal operation inspection items

① Check if the fan is running normally. After the fan is turned on for 30 minutes, check that the temperature rise of the oil bath bearing seat is at 6080 ℃ for normal operation;

② Check for any abnormal friction sounds from the windmill, and feel that there is no obvious vibration on the windmill casing;

③ Check if the circulation pump is operating normally and if there is any water leakage; Is the nozzle spraying water normally;

④ Check whether each valve is in the correct switch position;

⑤ Check the working condition of the water pump, regularly inspect and clean the sediment inside the nozzle head;

⑥ Check if the dosing pump is working properly, regularly remove impurities from the medicine box, and prevent blockage of the suction port;

⑦ Strictly prohibit pouring high concentration and large doses of liquid medicine into the water tank. This abnormal behavior will cause the collapse of the packing bracket inside the tower and serious damage to the water tank.

4. Shutdown precautions

① Check whether each device is working properly and propose maintenance precautions for the equipment during shutdown;

② After shutdown, the medicine in the dosing tank should be replenished, the oil in the Frp fan bearing seat should be changed or replenished, the water pump seal should be reinforced, sediment in the tower should be removed, and the nozzle should be checked for debris blockage;

③ Check whether each inlet and outlet valve is in normal working condition, and whether it opens and closes flexibly and effectively;

④ Before stopping the machine, check that all indicator lights in the electrical control box are turned on and the green light is on.

5. Shutdown steps:

① Close the automatic water replenishment valve;

② Open the drain valve in the tower water tank to lower the water level by 1/41/3

④ Turn off the circulating water pump;

⑤ Drain the water for about 1020 minutes, confirm that the water level drops by 1520cm, and then turn off the Frp fan;
