What is a spray tower? Spray tower manufacturer
There are many names for spray towers, including waste gas tower, acid mist tower, purification tower, scrubbing tower, absorption tower, adsorption tower, and acid mist spray tower.
A simple extraction tower with a spray tower is a hollow cylindrical body equipped with a liquid sprayer at the top, which disperses the liquid into small droplets and lowers them. The gas contacts the droplets in a countercurrent manner for mass transfer.
Working principle of spray towerThe acid mist exhaust gas is introduced into the purification tower through the air duct, passes through the packing layer, and undergoes gas-liquid two-phase absorption and neutralization reaction with sodium hydroxide absorption solution. After purification, the acid mist exhaust gas is dehydrated and defogged by the defogging plate before being discharged into the atmosphere by the fan. The absorption liquid is pressurized by a water pump at the bottom of the tower, sprayed down from the top of the tower, and finally refluxed to the bottom for recycling. The purified acid mist exhaust gas meets the emission requirements of the local emission standards in Guangdong Province and is lower than the national emission standards.
The advantages of spray towers are simple structure, low cost, low gas pressure drop, and no blockage. Currently widely used in wet desulfurization systems. Its main feature is complete openness. There are no other internal facilities except for the spray nozzle. The nozzle is the main accessory of the spray tower, and it is required to provide small and uniformly sized droplets to ensure the effective operation of the spray tower.
In flammable and explosive dust, wet dust removal spray towers can be used for treatment, and metal dust in hardware factories is also flammable and explosive dust. The interior of the spray tower has a high humidity, which can prevent dust from exploding. At the same time, using iron as the outer shell of the tower can reduce the impact of the explosion.
Spray tower is a simple tower type gas-liquid mass transfer equipment. The spray tower is a hollow cylindrical body with a liquid sprayer installed at the top, which disperses the liquid into small droplets and lowers them. The gas contacts the droplets in a countercurrent manner for mass transfer.
Spray towers can be used in high-temperature, flammable and explosive dust, and are suitable for dust treatment in industries such as chemical, hardware, electronics, and steel.
Spray towers are also commonly used deodorizing equipment, suitable for all large and medium-sized enclosed or semi enclosed spaces.
The spray tower has extremely high deodorization efficiency, small footprint, low operating costs, and can achieve automatic control. The product has a beautiful appearance and is available in single-stage, two-stage, and three-stage washing methods according to different occasions.
For mid section transportation, the deodorization washing tower is suitable for the unloading port of the transfer berth or the entire hall of the enclosed transfer station. In practice, suction ports are generally installed above the discharge port, where odorous gases and large amounts of dust are collected through negative pressure pipelines and connected to dust removal equipment and deodorization washing towers.
The deodorization washing tower is also suitable for odor control in garbage incineration plants. Used for deodorization in garbage dumps, the deodorization washing tower is suitable for sealed garbage discharge halls, large-scale leachate regulating pools, and other spaces with high odor concentrations.
Spray towers can be made of various materials, and companies need to choose the material of the spray tower according to their actual situation. Common materials include PP, stainless steel, iron, carbon steel, and so on.
If the fiberglass purification tower is to be used outdoors, anti freezing measures should be taken at the bottom water pool of the tower body in winter.
2. There is a liquid level mark on the bottom pool of this spray type washing tower equipment. Before use, it is necessary to inject absorption liquid according to the liquid mark. Attention should be paid to replenishing absorbent solution during use.
When installing the acid mist purification tower, the user should build a concrete foundation at a height of more than 150mm above the ground, and the water pump and fan should have a separate concrete foundation as required.
4. During transportation and installation, attention should be paid to the protection of the product, and the body and components should not be damaged.
When the purification tower leaves the factory, it will be packaged and transported in sections according to the specific situation, and installed and debugged on site by technical personnel.
When using, the purification tower should first turn on the circulating water pump for 2-3 minutes before starting the blower. When stopping, the blower should be stopped for 1-2 minutes before stopping the circulating water pump.
7. Please note that the user service will conduct a maintenance on the acid mist purification tower after one and a half to two years of use, checking the filling of the disc-shaped spray pipes and fillers, and cleaning them.
8. The acidity depth of the liquid in the bottom water tank of the tower and the degree of gas purification at the exhaust outlet should be checked regularly according to the usage situation. If it exceeds the standard. The absorbent in the bottom pool should be replaced.
1. Only operate when the water pump and fan are completely normal;
2. If the water pump is turned on 4102 after maintenance, attention must be paid to whether all parts of the water pump 1653 are normal;
3. Regularly clean and replace the packing to prevent increased air resistance and reduce treatment effectiveness. Due to the susceptibility of fillers to clogging by debris and the formation of crystals during exhaust gas treatment, it is necessary to frequently flush the fillers to prevent clogging. At the same time, it is necessary to regularly replace the packing; 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 is once every 3 years;
4. Regularly open the sedimentation tank sludge discharge valve (about one month) to remove wet dust and impurities;
5. It is necessary to ensure that the water pump operates with water to prevent damage caused by pump emptying.
What aspects should be paid attention to when installing a spray tower exhaust gas purification tower?
In order to prevent gas from carrying away the spray liquid, a gas water separator is installed at the top of the tower to effectively intercept the spray liquid. The circulating use of spray liquid may result in some loss during use. The circulating water tank located at the bottom of the tower should be replenished with spray liquid in a timely manner.
If the fiberglass purification tower is to be used outdoors, anti freezing measures should be taken at the bottom water pool of the tower body in winter.
