On asphalt fume treatment had a "clay adsorption" technology, which uses clay to absorb asphalt fumes, smoke pollution clay after incineration. This process is complicated, lime kiln manufacturers, high operating costs, and there is no secondary pollution problems, the actual operating results are unsatisfactory. Some enterprises according to their own conditions, asphalt smoke by burning method, the process is simple. Now some products using organic binders, emission of harmful substances during the heat treatment, but also by burning gas method, the gas burned in the stove, the burning temperature> 750 ℃, combustion volume heat intensity around 1300GJ / m3h. Over the years, in the part of the oil facility with a "wash oil absorption" technology. The use of wash oil absorbing asphalt fumes, the process shown in Figure 1. Bitumen Gas wash oil absorption saturation can be used as fuel other furnaces, reduce costs, put into better use. Electric furnace kiln electric furnace kiln applications in recent years gradually increased, mostly for heat-treated MgO-C, long outlet, skateboards and other products, but also for skateboarding, long nozzle firing and burning of silicon nitride and other special refractories system. Electric furnace production recorded live, convenient and reliable temperature control and good production environment. Electric furnace kiln, lime kiln, mostly for heat treatment furnaces continuous furnaces for many, the activity of the kiln, using temperature is generally 200 ℃ -350 ℃, the installed power 150kw-300kw. Roaster kiln mostly intermittent jobs, mostly in the use of temperature 400 ℃ -700 ℃, with product varieties and installed power requirements of the heating rate, the difference is large, green lime kiln, more than 250kw-500kw. The production of silicon nitride bonded SiC brick kiln electric furnace temperature <1400 ℃. Pollution environmental technology application and promotion of refractories plant in existence, so that Shanghai, Beijing, Guangzhou and other cities, to build in the city of refractories plant, relocation or take measures to limit discontinued. Industrial furnace refractories are key sources of pollution, in recent years, focusing on the promotion of environmental protection measures are: a) high-efficiency filter air purification dust. Smoke purification focus on the promotion of efficient bag filter, bag limits due to the required temperature of flue gas into the bag filter is less than 260 ℃ -300 ℃. After the furnace flue gas treatment through efficient dust collector, dust content can be controlled in less than 100mg / m3; b) asphalt fume treatment. Skateboards, and other products require dipping tar MgO-C, and then baked in a kiln, the removal of volatile, thus producing asphalt fumes, the workplace and the surrounding environment pollution. _ _ Active lime kiln lime kiln furnaces sky (high merchant) provided by LUOZHUANG Kiln Ltd.
