It is understood that the scope of participation in the special transformation is the use of industrial gas production enterprises in the region, with emphasis on high-temperature liquid metal production enterprises using industrial gas. There are currently 39 gas-using enterprises involved in this technological transformation, including 26 natural gas-using and 13 coal-to-gas enterprises. According to the requirements, enterprises involved in the transformation, regardless of facilities and workshops, must install automatic alarm devices for flammable and explosive gases. At the same time, enterprises with conditions should install safety interlocking control devices.
Li Xueming, director of the Nanxun District Safety Supervision Bureau, said: "The biggest advantage of these two technical reforms is that once a gas leak occurs in a production enterprise, the device will alarm and automatically cut off the valve of the gas supply pipe." Alarm or safety interlock protection will eventually eliminate the hidden dangers in the bud and achieve safe production.
For example, in the case of enterprises that use natural gas, in accordance with this technical reform plan, flammable gas alarms or safety interlocking control devices should be installed at appropriate locations around the natural gas use workshop or equipment to enhance the management of abnormal conditions such as leakage. If the gas consumption is small or the use interval is short, the hand-held gas leak detector can be used for inspection and other measures to strengthen daily safety management.
It is also known that in addition to the technical reforms carried out by these 39 companies, many companies that use natural gas have already prepared for the rain. When the natural gas was introduced, automatic alarm and interlock control systems were installed. Such as Yongda Bicycle Materials (Huzhou) Co., Ltd., Hengwei Aluminum, Hengyi Food and other enterprises.
According to Fan Hualin, the person in charge of safety production of Yongda Bicycle Materials (Huzhou) Co., Ltd., the company originally used liquefied gas. Last year, it began to use more safe and environmentally friendly natural gas. In order to prevent it, it was installed when the gas was opened. Automatic alarm and safety interlock.
Although the technical reform has been completed before, Fan Hualin said that if there are better technical defense products that can replace the existing "double insurance", the company is willing to try, "after all, for the enterprise, safety is the first. â€
After the investigation has been completed in May, from this month to next month, Nanxun District will formulate a technical transformation plan based on the actual situation of the use of different gas-type production enterprises. In 2012, it is necessary to ensure that 60% of the enterprises involved have completed the technical transformation target. In 2013, all companies completed the technical transformation.

Dimmable Led Grow Lights For Plants
1. Adjustable spectrum: adjustable light LED Grow Light can adjust the wavelength and spectrum of light according to the photosynthesis needs of different plants. Different wavelengths of light have different effects on the growth and flowering of plants, and by adjusting the spectrum, the growth of plants can be maximized.
2. Adjustable light intensity: Adjustable light Grow Light can adjust the light intensity according to the needs of different growth stages of plants. In the early stage of plant growth, it can provide strong light to promote the growth of seedlings; During flowering and fruiting, light intensity can be reduced, saving energy and increasing yields.
3. Adjustable light time: Adjustable light Grow Lights can adjust the light time according to the photoperiod needs of plants. Some plants need long periods of light, while others need shorter periods of light. By adjusting the light time, you can simulate the natural environment and promote the normal growth of plants.
4. Energy saving and environmental protection: The dimmable Growth Light uses LED light source, which has the characteristics of high efficiency and energy saving and long life. Compared with traditional fluorescent lamps or high-pressure sodium lamps, LED light sources are more energy efficient and environmentally friendly, and can provide higher light efficiency.
5. Safe and reliable: dimmable plant lights use low voltage power supply, do not produce heat, will not burn plants. At the same time, it also has over current, over voltage and over temperature protection functions to ensure the safety and reliability during use.
