#Follow Longzhong across the sea: Beijing Public Research Unit part-1

This time I am in charge of a case of a public research unit in Beijing, which mainly needs to simulate the reaction of particle collisions in an ultra-high vacuum environment. In fact, this case was not looking for our assistance at the beginning. Due to various reasons, the follow-up came to us for emergency help.
Industrial Exhaust System

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.
Industrial Exhaust System

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.
Industrial Exhaust System

Automatic control of RTO industrial waste gas treatment system

Longzhong can automatically control the operation of RTO industrial exhaust systems for customers. It can also automatically calculate the heating temperature and control the quality of filtered exhaust gas to achieve the best exhaust gas purification effect. This treatment method that first decomposes VOCs volatile organic waste gas into harmful substances and then keeps it warm and discharges the waste gas will not cause too much burden on the environment.
Industrial Exhaust System

DeNOx Nitrogen Oxygen Removal System SNCR

Through Longzhong PLC programming to control the entire SNCR technology process, it can achieve data collection, continuous control and program control of the exhaust system... and other functions to realize the entire DeNOx denitrification system for you. Fully automated control!
Factory Service Air Conditioning System

Industrial air conditioning system

Factory air conditioning systems usually pursue stable environmental control functions.
