How to avoid the chemical processing enterprises boiler boiler water pollution chemical processing companies how to avoid water pollution? It is well known in the food production process, many sectors need to use boilers, such as cooking, faced with the problem of sewage treatment, also with a certain level sterilization, dry, wine and so on. In the country's growing emphasis on environmental protection, continue to increase supervision of enterprises under the enterprise adoption of what approach to avoiding disadvantages, complete sustainable development? Primary, flue gas collection equipment processing equipment. Since SMEs by financial constraints, skills, and other places, a time can not be cut all the transformation, it is possible, after passing through the coal-fired boiler exhaust gas purifying exhaust purification device tail device, such as a fume hood, an exhaust gas collection processing device, effectively to prevent the direct discharge of black smoke, a serious impact on the surrounding environment. Second, clean power conversion, such as coal gas, coal to electricity. I learned that a beer factory invested more than 10 million will replace all coal-fired boilers, gas-fired. Now, 180 tons of coal biomass cofiring steam boiler plant now farewell all coal, burning a low nitrogen gas cleaning switch, effectively reduce pollution. And compared with previous coal-fired boilers, coal saving more than 80,000 tons per year business. Again, the original boiler for energy saving, skills promotion. Programming with the furnace arch, adjust the secondary air to optimize the planning aspects of the planning grate, uniformity of air distribution, so that plenty of fuel burned, burning power progress. It is understood, Shanxi, a business research and development of environmentally friendly gas-solid two-fired boiler using low-grade nitrogen incineration furnace desulfurization, flue gas purification tail, the whole active control and other skills to complete energy efficient, which means that the stop, auto-run and clean intent emissions. Eventually, equipment sewage treatment facilities. Many food processing plants because of waste water, untreated sewage discharge and perhaps willful discharge, was ordered rectification probably ordered the closure of news after another. Because food processing wastewater organics, heavy metals, a high concentration of suspended solids, wanton discharge highly contaminated water, soil and living environment. All in all, China's boiler industry, neither sunrise industry, not a sunset industry, food processing industry but indispensable industry. However, along with constantly promote the national energy saving policy, whether it is food processing enterprises, is still food machinery manufacturing enterprises, must always assume social responsibility, uphold the concept of energy saving, reduction may reduce pollutant emissions.

Boiler for Rubber industry

Rubber Vulcanizing need high temperature steam, while steam generation is produced by steam boiler. In rubber industry, steam boiler play an important role which supply high temperature steam. Steam boiler fuel can be: Rice Husk, Coal, Lignite, Washery Rejects, Char, Indian/Imported Coal, Petcoke, Pith, Wood etc. Boiler prices for steam generation in rubber industry, please contact our online service, and we need to comfirm the capacity, pressure, temperature.

Boiler structure have? The whole structure, including boiler and boiler auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.

Box Group in their own development, bearing in mind the social responsibility, personally, set an example, to carry forward traditional Chinese virtues. We hope that through this way, to get more attention of the community. We work together to build a healthy growth of childhood for the children, to give them a future full of faith!
