1) salt during the air pollution, exhausted mainly from the coal-fired boiler heating systems and cogeneration power plant boiler soot, dust and salt boiling drying system exhaust discharged from the bed and the like.
2) Salt industry wastewater is divided into two types: net waste water and turbid waste water: the former is equipment cooling water, equipment washing water, and circulating water. The latter is the wastewater discharged after direct contact with the salt raw materials in the production process, such as salt mother liquor, pickling wastewater, equipment leakage brine, acid and alkaline wastewater discharged from thermal power station water treatment.
3) Waste slag discharged from salt plant (mine), mainly waste discharged from industrial boilers with coal as fuel, including fly ash collected by dust collector and slag discharged from the bottom of the furnace; and evaporation system during salt production Excreted salt gypsum or coarse slag, etc.
4) The noise in the production process of the salt production plant mainly comes from the noise of blowers, air compressors, induced draft fans, pumps, salt shakers, steam turbines, desuperheating or decompression devices, as well as boiler steam and steam turbines. Salt accidents, steam exhaust noise, etc.
5) Environmental pollution caused by salt mine drilling water-soluble mining: oily wastewater, leakage brine during transportation, ground subsidence, etc.
We started to manufacture traffic signal pole from 2001 and exported from 2002.
Our firm introduced whole set of good-sized numerical control hydraulic folding equipment(1280/16000) as well as equipped with a series of good-sized professional equipments of armor plate-flatted machine, lengthways cut machine, numerical control cut machine, auto-closed up machine, auto-arc-weld machine, hydraulic redressing straight machine, etc. The firm produces all sorts of conical, pyramidal, cylindrical steel poles with production range of dia 50mm-2250mm, thickness 1mm-25mm, once taking shape 16000mm long, and large-scale steel components. The firm also is equipped with a multicolor-spayed pipelining. At the meantime, for better service to the clients, our firm founded a branch com. The Yixing Jinlei Lighting Installation Com, which offers clients a succession of service from design to manufacture and fixing.
