Industrial GEX exhaust windmill system PLC automatic control

What is GEX? It is a general exhaust, which is a very basic ventilation device. As the production line of the customer's factory gradually expands, the exhaust volume calculated by the factory at the time of the original construction is seriously insufficient and cannot meet the exhaust requirements of the clean room. The original windmill was integrated to achieve interactive operation.

Automatic control TO direct-fired incinerator

The customer entrusted in this case, the waste gas to be treated in the factory is corrosive. Not only that, the waste gas will combine with the air to form hydrochloric acid at high temperature, so a TO direct-fired incinerator must be used. The owner hopes that Longzhong can assist in automating the exhaust process of the TO direct-fired incinerator.

Electric damper repair

The electric damper used in the dust collecting windmill system in the customer's factory continued to emit abnormal noise during operation, and the pressure and flow were always in an unstable state. The owner directly placed an order for a new electric damper, and planned to ask Longzhong to help them replace the entire set of old dampers.

Acid-base exhaust system Scrubber

The wet scrubber (Scrubber) uses alkaline (NaOH) circulating water to wash the acidic waste gas discharged from the process, and uses the principle of acid-base neutralization to neutralize the exhaust gas without being corrosive. The harmful substances in the working environment are extracted by the exhaust windmill so that they are below the limit value, so as to avoid the harm of poisoning of the workers.

Horizontal scrubber

Using the huge area generated by the filler, the gas and the drug are fully and closely contacted, and it is the chemical neutralization effect that allows the air to achieve the cleaning effect. There are many factors that determine its efficiency, such as: the speed of the gas passing through the tower, the choice of packing, the height of the packing layer, the concentration of the liquid medicine, the cleanliness of the circulating water, the specific surface area, etc.

Automatic Controlled Exhaust System - RTO

Generally, "volatile organic compounds" are mostly solvent waste gas or odorous organic compounds.
Components include: carbon, hydrogen, oxygen, nitrogen, sulfur, halogen and other elements.
The treatment principle of RTO incineration is to supply enough oxygen at the same time at high temperature,
Carry out mixed combustion and convert into odorless and harmless gas.

DeNOx Nitrogen Oxygen Removal System SNCR

Selective Non-Catalytic Reduction (SNCR)
is the process of removing nitric oxide or nitrogen oxides (NOx) from flue gas. In contrast to selective catalytic reduction (SCR), this method does not use a catalyst to assist, but its purpose is also to decompose nitrogen oxides in flue gas into nitrogen (N2) and water (H2O).
