On reasons of heating energy consumption of hot water excellent quality dhl boilers and energy-saving technical measures: Henan fast boiler Xiao Bian below take you to understand the transformation of energy-efficient hot water boiler heating level of:
What is our Product Range?
4 tons of gas steam excellent quality dhl boiler blowdown should pay attention to what matters should be ① the sewage at low load, high water level. Close attention should sewage water level in the furnace, each sewage water level in the boiler to reduce the 25 to 50 mm is appropriate. ② if not through to the sewage outfall end of the tank or sewage well, and no protective equipment must be available in the sewage do know that no one is near the outfall place to avoid accidents when sewage. ③ particular sewage operation is as follows: two with each boiler blowdown valve, the first (the one away from the boiler) when only the second full discharge, then only slightly open first drain valve (latest one from boiler) to preheat the pipe until the pipe gradually turn up after preheating only a first drain valve, the sewage must be completed first gradually turn down the drain valve, shut off and then only the second drain valve, the purpose of doing so is to use only the first discharge, when leakage to keep only the first, only the second control emissions can still be used. When sewage if there is impact noise in the sewage, that is only the first drain valve should be closed until the small impact sound disappears, then slowly turn up the sewage should not be carried out continuously, so as not to affect the water cycle. ④ After the completion of the sewage close the drain valve, the drain valve is tight check, check is: closing the first drain valve only after some time, the second test only touch on the drain valve conduit hand, if the cooling blowdown there must be leaking valve.
In mid-March this year, Shenyang City, the first excellent quality dhl boiler industry issued emission permits. Plan will livestock poultry, dairy products manufacturing, automobile manufacturing and other industries 29 issued emission permits, issued by the maturity shall not sewage, sewage behavior of errant card companies to investigate and punish. This is also the industry's first Shenyang boiler emission permits.
According to the State Department "to control emissions permit system implementation plan" and the Ministry of Environment "discharge permit management approach", 2017 in Shenyang City has completed thermal power, paper, cement, electroplating, pharmaceutical, pesticide, textile printing and dyeing industry, 54 enterprises license issuance of work. 2018, the city completed the issuance of emission permits 128, including iron and steel industry 5, slaughtering and meat processing industry 106, 16 water treatment industry, ceramic industry one, according to industry certification and time-bound national requirements, so that " should be sent to do hair. "
This year, Shenyang City, according to "stationary sources of pollution permits Classification Catalog" requirement, will be livestock poultry, dairy products, Condiments fermentation products manufacturing, food manufacturing other convenience food, wine manufacturing, footwear, plywood manufacturing, bamboo and rattan wood furniture manufacturing, polyvinyl chloride, phosphate fertilizer, automobile manufacturing, battery manufacturing, non-metallic waste and scrap metal processing, garbage to hazardous waste sludge as fuel for thermal power generation, sewage treatment and recycling, environmental control industry , heat production and supply, electroplating facilities, sewage centralized treatment of industrial waste water and other 29 industries issuance of emission permits. Up to now, has been launched boilers, water treatment, ceramics, automobile manufacturing, battery manufacturing, phosphate fertilizer industry and electroplating processes work permits issued.
Shenyang Ecological Environment Agency, responsible person, emission permits to take "a card-style" management, so that all the laws and regulations of the environmental requirements of an enterprise integration to a convergence of the proposed permit up to implement the main responsibility for polluters. A company issuing a discharge permit, enterprises through the establishment of self-commitment, self-monitoring, accounting records and regular reporting system has proven its emissions by law, to further strengthen fine management.
Shenyang in the discharge permit issued during the EIA procedure will be incomplete, excessive emissions, there is the issue of corporate environmental management ordered rectification to achieve "issued an industry, to clean up an industry, an industry specification, an industry discharge standards." In the future, Shenyang will be implemented in accordance with the regulatory card issuing companies to carry out law enforcement inspection post card, after intensive license management, enterprise undocumented sewage discharge permits and do not follow the behavior will be investigated according to law.
