The structure of this product is mainly composed of stainless steel shell, combustion system, washing system and slag cleaning system. In terms of air intake, compressed air plus fresh air intake is used to improve the efficiency and reliability of product operation. In the spray system, the method of combining circulating water pump and automatic water refill is adopted, and the fan is in the form of one use and one backup. These process characteristics make the product greatly guaranteed in terms of safety and reliability. The internal combustion chamber uses a special pressure relief device, which can work normally even when the internal pressure is suddenly increased, and it is equipped with a nitrogen inlet for greater safety. In terms of dust collection, the method of static pressure deposition is used, and the deposited dust is discharged through the slag discharge port, which makes the dust collection and treatment easier and more effective. Measured by authoritative departments, the removal rate of silane (SiH4) is ≥ 99.99%, and the purification rate of ammonia (NH3) and other water-soluble gases is as high as 99.99%.
Stainless steel silane combustion purification tower working principle:
This product is made of high quality stainless steel raw materials, according to the characteristics of silane contact with air and spontaneous combustion, so that silane in the combustion chamber and air contact combustion, the gas after combustion through the packing layer and then into the combustion tower spray chamber, after spray treatment, so that the exhaust gas and the neutral circulation liquid contact reaction, and then into the dehydrator dehydrating treatment by the exhaust fan discharged into the atmosphere.
Stainless steel silane combustion purification equipment maintenance
1, the stainless steel silane combustion tower must have a special person responsible for management, set the inspection record table, and regularly check whether the fan and water pump operate normally every day; Whether the liquid level in the tank is within the normal scale.
2. The stainless steel silane combustion purification tower generally adopts the suction type, that is, the fan draws air from the top of the silane combustion purification tower, and adopts the form of double fans, one is used and one is prepared. The fan should be switched regularly every month.
3, check whether the pump is running normally, check whether the flow meter is normal. The water supply valve must be always open, and the switch can be adjusted according to the ammonia content in the exhaust gas.
4, if the stainless steel silane combustion purification tower is in the form of double pumps, before opening any pump, check the corresponding inlet valve, keep it open, close the standby inlet valve, and then open the pump, and the pump should be switched every month.
5, according to the use, open the sewage outlet every month to remove SiO2 dust and debris.
6, the fresh air supplement port is the key part of regulating the internal negative pressure of the equipment. Pay attention to adjust the valve position of the fresh air, in the place to do a clear mark, and hang a warning sign, do not arbitrarily move!
7. The compressed air port and nitrogen port on the equipment must be connected.
8, the normal operation of the water supply valve is adjusted to 200 ~ 300l/h, if the water pump fails, the water supply valve must be opened to the maximum flow, in the shortest time to repair the pump.
9. When the compressed air fails, the fresh air valve is adjusted to the maximum, and a little open when normal.
10, fan and water pump switch program, start, first open the fan and then open the water pump; When shutting down, turn off the water pump and then the fan
11. The neutralizing liquid of the equipment should be replaced once a week. Before the replacement, shut off the water pump and drain the liquid. Then open the water refill valve to the maximum and add water.
12, the nozzle and stainless steel ring packing inside the equipment should be checked and cleaned once every three months according to the actual use. When replacing the filler and nozzle, open the manhole. The filler and nozzle should be replaced regularly (about once a year).
13, nitrogen inlet and compressed air inlet are equipped with a gas flow meter and gas control valve, according to the exhaust gas flow through the gas regulating valve to adjust the compressed air and nitrogen intake, normal conditions are generally to open the compressed air to the maximum, nitrogen to 1.2m3/h is appropriate.
