Hot selling FRP purification tower waste gas absorption spray tower FRP desulfurization towe

  Product introduction of FRP desulfurization tower: the acid mist waste gas is introduced into the purification tower through the air duct
After passing through the packing layer, the waste gas and sodium hydroxide absorption liquid are fully contacted, absorbed and neutralized by gas and liquid
After purification, the acid mist waste gas is dewatered and demisted by the demisting plate, and then discharged into the atmosphere by the fan

 
Working principle of FRP desulfurization tower:
The acid mist waste gas is introduced into the purification tower through the air duct
After passing through the packing layer, the waste gas and sodium hydroxide absorption liquid are fully contacted, absorbed and neutralized by gas and liquid
After purification, the acid mist waste gas is dewatered and demisted by the demisting plate, and then discharged into the atmosphere by the fan
The absorption liquid is sprayed at the top of the tower after being pressurized by the water pump at the bottom of the tower, and finally returns to the bottom of the tower for recycling
The purified acid mist waste gas meets the emission requirements of the local emission standards of Guangdong Province and is lower than the national emission standards

 
Product features of FRP desulfurization tower:

high dust removal and desulfurization efficiency
When alkaline washing water is used, the desulfurization efficiency can reach 85%
2
the equipment occupies less land and is easy to install
3
low water and power consumption indicators
4
corrosion resistance, no wear and long service life
5
the equipment is reliable and easy to maintain

 
Product structure of FRP desulfurization tower:
The packing layer in the spray tower is used as the mass transfer equipment of the gas-liquid contact component
A packing support plate is installed at the bottom of the packing tower, and the packing is placed on the support plate in a disordered manner
A packing pressing plate is installed above the packing to prevent it from being blown by the rising air flow
The spray liquid of the spray tower is sprayed onto the packing through the liquid distributor from the top of the tower and flows down along the surface of the packing
The gas is sent from the bottom of the tower
After being distributed by the gas distribution device, it continuously passes through the gap of the packing layer in countercurrent with the liquid
On the packing surface, the gas and liquid are in close contact for mass transfer
When the liquid flows downward along the packing layer, wall flow sometimes occurs, and the wall flow effect causes uneven distribution of gas-liquid two phases in the packing layer, thus reducing the mass transfer efficiency
Therefore, the packing layer in the spray tower is divided into two sections, and a redistribution device is set in the middle to spray onto the lower packing after redistribution

 
Precautions for FRP desulfurization tower:
1
Regulation of circulating water volume: it is determined by the water supply pump of the spray tower
When one boiler is operated, one can be opened
When two or three boilers are operated at the same time in winter, all the two pumps can be opened
The flow of the mud pump should be adjusted according to the flow of the circulating pump to make it equal
2
Dosage in the dosing tank in the spray tower: when one boiler is operated, add 2 bags of alkali and 5 bags of hydrated lime
If two or three boilers are operated in winter, the dosage can be increased by corresponding multiples
3
The sedimentation tank of spray tower shall be cleaned frequently, once a week in summer and once three days in winter
4
During the blowdown of the ash water separator, the blowdown shall be conducted once per shift, and the blowdown valves shall be opened separately until there is clean water discharged
5
The above rotating parts shall be inspected and oiled frequently, and the faults shall be eliminated in time to ensure the desulfurization effect of the spray tower
6
Pay attention to safety when going up and down stairs, have independent security and mutual security awareness
7
After the work is completed, it shall be cleaned up in time to ensure that the site is clean when people walk
