low pressure cotton shell large boiler for rice mill
4, good sealing performance
Boiler body as aluminum silicate blanket insulation materials, welding and pipeline are set ultrafine centrifugal glass cotton insulation materials, two-pronged approach to ensure good sealing performance of the boiler, the heat loss to a minimum.
Forced circulation low pressure cotton shell large boiler for rice mill water or steam only in the difference in density between water and steam as the driving force, and requires a certain power to the pump is circulated in the heating duct. Forced circulation oven due to the good water circulation, speed requirements of Sheung Shui is very low; the working pressure is generally more large, high boiler tube material and wall requirements. Forced circulation boiler drum is no longer necessary, you can have the drum, the drum can not; but for a higher pump head requirements, power consumption is greater. When the pump stops running, the pot of water flow is stopped, the need for a reliable way to prevent moisture pot of water hammer.
Instructions for the use of steam low pressure cotton shell large boiler for rice mills
Steam boiler is a common production equipment with high efficiency and high firepower. However, it is also dangerous. If it is not used properly, it will bring unnecessary trouble. Therefore, it is necessary to be familiar with the use instructions of steam boilers. Then, based on many years of experience, the editor summarizes the usage specifications as follows.
In mid-March this year, Shenyang City, the first low pressure cotton shell large boiler for rice mill 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.
