In order to reduce the emission of nitrogen oxides, HLD retrofitted the existing natural gas boilers with low nitrogen.?Through various tests and type inspections of the boiler, it is shownthat the emission reduction of nitrogen oxide pollutants in the tail gashas reached more than 80%, and its reduced standard emissionconcentration is stably controlled below 30 mg / m3.

In order to reduce waste gas emissions, HLD uses RTO high-efficiency regenerative incinerator to carry out incineration and oxidation treatment of waste gas and oxygen up to 870 ℃. The heat of high-temperature gas during oxidation is "stored" by the regenerator for preheating the newly entered waste gas, which not only reduces the fuel consumption required for temperature rise, but also makes the pollutant removal rate reach more than 99%?

The company is equipped with many buses to pick up employees to and from work at different times, fully advocating a green and low-carbon life

The company attaches importance to the prevention and emergency disposal of production safety accidents, and has special emergency plans, on-site disposal plans, emergency disposal cards, etc. for greater safety risks. According to the emergency drill plan, the company regularly organizes employees to carry out the training and drill of the emergency plan every year, so as to ensure that employees master the initial disposal methods of accidents and the ability of emergency escape.
