    Fire-proof material application and popularization of the technology of environmental protection

    Problems of pollution in the production of refractory plant, Shanghai, Beijing, guangzhou and other big cities, to build the refractory plant in the urban area, the relocation or limit production measures. Refractory material is a key pollution source of industrial furnaces, in recent years, focus on promoting environmental protection measures are: a) the efficient filter purification smoke. Soot purification was promoting efficient bag dust catcher, due to the filter bag limit, request into the bag precipitator flue gas temperature is less than 260 ℃ to 260 ℃. Furnaces flue gas after dealing with the high efficiency filter, the ash content can be controlled in less than 100 mg/m3; B) the processing of asphalt gas. Skateboarding, magnesia carbon brick and other products need to dip the tar, and then roasting in furnaces, removing volatile, so produce asphalt gas, in the workplace and the surrounding environment pollution.

     

    Used on asphalt gas processing "clay adsorption process, use clay absorbs asphalt gas, pollution of the clay for incineration. It is multifarious, running cost is high, and secondary pollution problems, the actual running effect is not ideal.

     

    Some enterprises according to their own conditions, the burning of asphalt smoke, the method of simple technological process. Now some products using organic binder, harmful emissions during heat treatment, also adopts the method of burning gas, the waste gas in hot blast stove burning, burning temperature > 750 ℃, burn around 1300 gj/m3h volumetric heat intensity.

     

    In recent years, on the part of the oil facilities adopted "wash oil adsorption process. With wash oil absorbing asphalt smoke and its technological process is shown in figure 1. After washing oil asphalt gas saturated adsorption, can be used as other fuel furnaces, reduce cost, use after the production effect is good.

     

    2.6 advanced furnaces and backward furnaces coexist

     

    Since the 80 s, the refractory industry rapid development, China has become the world refractory material producer and exporter. Some foreign joint venture or wholly foreign owned enterprise to enter the Chinese market, they tend to have strong economic strength and advanced production technology, has a good reputation in the international market, but its industrial furnaces, mostly USES the technology of our country, which reflects the advanced furnaces in our country has obtained foreign counterparts.

     

    Private enterprises under the market economy is developing rapidly, there are some good benefit enterprise has built high standard production line, but overall, from private enterprises starting point is low, equipment level is relatively backward, and there are a number of soil down-draft kiln and vertical kiln. This causes advanced furnaces furnaces and backward situation, backward furnaces and the requirement of energy conservation and environmental protection does not adapt, advanced furnaces should also improve constantly.
