Around at 6:00 on November 22, Guang'an City, Sichuan Province Economic Development Zone Industrial Zone, a company Newbridge burst distillation kettle explosion, the roof 20 square meters of workshop collapse occurred, had not resulted in a fire, but there are four people were injured, It has been transferred to hospital for treatment.
Suddenly the accident, the specific reasons unknown, Guang'an City, the municipal government attaches great importance to the explosion, immediately launched an emergency contingency plans, multi-power Guangan Economic Development Zone, safety supervision, environmental supervision, public security and fire protection, first time to scene to carry out rescue and subsequent disposal.
Distillation pot is directed chemical production still pot used in this step, also has a greater risk of leakage and fire accident-prone equipment. In recent years, leaking reactor, distillation kettle and other equipment, fire, explosion accidents occur frequently, mainly because often kettle equipped with a toxic, harmful hazardous chemicals, the accident consequences more serious than the general explosion, either to persons or property caused serious irreversible effects.
Distillation is one essential step in many process industries such as chemical industry, brewing, paper, food processing, it will involve the distillation process. Steam boiler equipment for the needs of enterprises to provide a distillation excellent choice. Steam boiler steam output, after a series of treatment steps of cooling, purification, extraction, etc., provides excellent quality of distilled water, for the production needs.
Fang fast has a very rich experience in R & D, manufacturing and sales of natural gas steam boilers, since practitioners, R & D and innovation has always insisted on clean fuels. One condensing gas steam boiler, gas steam boiler water, ultra-low nitrogen gas steam boiler ...... date, more than 200 kinds of types of boilers.
Over-temperature protection, over voltage protection, abnormal power protection, scale online monitoring, frost protection, the water level is too high, too low to protect and increase water protection than the traditional four fifth protection mechanism, so a series of protective measures, all-round to ensure the safety and reliability of operation of steam boilers, select the users of our products is very much at ease, peace of mind.
After the transformation of coal-fired paper mill boiler chemical cleanings need to pay attention to what selection after selection of the transformation of coal-fired boilers need to pay attention to what? Since the state efforts to control air pollution is growing, Beijing and its surrounding areas will have to carry out the transformation of boilers, according to the new regulations of environmental protection law, the boiler equipment polluting strict supervision, strictly limited to the emission of pollutants. Here, the transformation of coal-fired boilers to gas boilers renewal as an example of a simple selection method resolution. (1) calculate the total load of the boiler room, in order to carry out a simple programming model of the boiler. (2) According to the analysis of the actual situation, that satisfies the requirements of the pump head. (3) In addition, the choice of the boiler pump flow can not be too large, it is desirable good, otherwise easily lead to unnecessary waste. (4) After the pump selection, may be selected according to the type of water softener tonnage of the boiler, the boiler to satisfy an operational criterion for the better choice. (5) Further, in the selection process will be a constant pressure device, water separator, etc. Selection of the sump, which are carrying out the transformation process in the boiler, the boiler renewal selection must take into account The problem. In addition, in the selection process considerations in addition to auxiliary elements arranged, necessary required boiler operation, the boiler is the consideration of price, and different types of auxiliary boiler configuration combinations, the resulting price not the same, it is recommended to measure price on the basis of a simple and efficient operation of the above.
Excellent configuration: Supporting world famous burners, advanced control systems (the main original components are imported parts), valves and pumps all adopt national high-quality products, excellent paper mill boiler chemical cleaning accessories configuration for the safe and stable operation of the boiler to provide a strong guarantee.
Three common paper mill boiler chemical cleaning combustion boiler has its advantages and disadvantages in the field of comparison described power plant and uses a relatively large vessel, it is primarily an energy conversion device, its main role is to convert fuels to steam or high-temperature water. So what specific boiler burning it today is to introduce three common combustion boiler as well as their advantages and disadvantages:? Diffusion combustion Pros: This combustion is not pre-mixed, but the nozzle mouth the fuel gas interdiffusion, and then combustion. Combustion is relatively simple, relatively stable flame. Disadvantages: Due to a longer flame, it is prone to the phenomenon of incomplete combustion, will produce more carbon monoxide and nitrogen oxides, to the full use of the boiler fuel, to enhance the thermal efficiency boilers, and it is difficult to meet emission standards boiler. 2. The advantages of the premix combustion mode: premixing air and gas, the heat transfer multi-mode radiator, the intensity of heat transfer improvement. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency. Disadvantages: the ratio of the premixed combustion in claim accurate fast burn rate, burn sufficiently uniform radiant heat transfer efficiency of the high flame temperature below 1200 deg.] C, all complete combustion gas temperature and NOx production low, condenses, good heat recovery and high efficiency. 3. A flameless combustion space before the combustion method of uniformly mixing the combustion gas with a gas boiler. When using this method, no need to obtain a gas in the air surrounding the combustion of oxygen required for the process, and only air mixture reaches the combustion zone to achieve complete combustion of the moment. These are the three common boiler combustion, combustion in the choice of the time required for combustion of different advantages and disadvantages, compared choose, because choosing a way to compare the earth to enhance the thermal efficiency, so choose a good combustion or more important.
