My company for the cupola flue gas temperature, dust and other unstable situation, the cupola dust removal system in-depth study, Combined with years of experience in my company, I developed the cupola dust removal system has the following characteristics:
Cooling cooling system is safe and reliable, and over the years by theoretical calculations to derive the actual site dataThe cooler design more reasonable size, smoke temperature drops below 100 ℃.
Baghouse inlet at increased temperature protection control system, the installation of a temperature sensor and a cold inlet valve in place, when the intake air temperature is higher than the set temperature, the valve automatically play cold open, incorporation of wind
Baghouse dust removal efficiency, up to 99%, especially for fine dust collection efficiency rate was above 99%. At the same time the company for high temperature, high oil smoke environment do step into a research and development. By the environmental protection department, its flue gas emissions can meet emission standards.
Desulfurization efficiency cyclone tower cupola dust removal system as the final stage, 90% of the desulfurization efficiency , SO2 emission concentration: ≤300mg / Nm3.
1, the key components of the external water cooling system long cupola furnace.
2, flue gas heat exchanger inlet temperature: 760-800 ℃, the outlet temperature of 450 ℃ -550 ℃.
3, Material: heat-resistant shell made of 304 stainless steel, the inner shell and tubes of heat-resistant stainless steel using 310S.
4, the unique production technology tubes longevity: Our tubes produce seamless stainless steel pipe used in all use a special mold calendering, compared with stainless steel plate under the cut material by molding and then welded reasonable structure, long service life.
5, the heat exchanger has a stainless steel expansion joint Central ensure free expansion of the heat exchanger.
6, flue gas heat exchanger inlet section has an automatic cleaning device, the timing of the tubes were blowing through the relay, so that the inner tubes kept clean 



Automatic after cupola furnace iron materials, coke, limestone and alloys: a person can achieve automatic operation of control, iron materials, high-precision coke, limestone and alloys, low error rate ingredients.



After the electric furnace Automatic iron alloy materials: one person can achieve automatic operation of control, iron materials, and alloys of high-precision, low error rate ingredients. Burden preparation required silicon, manganese alloy materials were stored in two silos electric high platform, the platform is located on the furnace, followed by two electromagnetic vibrating feeder hopper to weigh ingredients, with the alloy materials needed and weight, when the electric car charging forward line to the alloy unloading position, two-way belt starts weighing hopper discharge opening, belt conveyor transported to the alloy material feeding hopper car alloy warehouse. Open the door in the feed hopper bottom alloy metal materials plus car after opening, the alloy material discharged into the feed hopper car vibrations, added by the electric car charging electric furnace to vibration. Automatic electric charge with gold, high dosing accuracy. Computer control feeder formulated precise ingredients, can be automatically shipped with 5 to 12 kinds of alloy charge. Static accuracy up to 0.1%, batching accuracy of up to 1%.

Bake packer: high heat sealing, heat evenly, energy efficient, easy to operate, fully automated operation to achieve full control, with a variety of security features. Since preheat burner is the burner, preheater, ejector burner tiles and organically combined into one; the theory can improve fuel combustion temperature, with a compact, high thermal efficiency and significant energy saving features. Efficient regenerative bake ceramic package using a semi-closed system baking methods, the use of high-frequency switching equipment, high-temperature exhaust gas and combustion air and gas in the ceramic regenerative body alternately by each other sufficiently heat exchange combustion air and gas preheated to about 1000 ℃, increasing its enthalpy, stable, efficient and energy-saving combustion. Using regenerative combustion technology to improve the uniformity of temperature within the package, so that the liner temperature more uniform, elimination of local hot spots, at least you can make the lining of life increased by 10%. Reduce harmful gas emissions. Because of combustion, greatly reducing harmful gases such as CO 


Electric ball of dust cover: do not affect iron lifting, forms, can achieve automatic control. High collection efficiency, accessibility rotate 360 degrees, to achieve "one with two intermediate frequency furnace" two smelting furnaces and chemical condition of the ball when sharing a capture hood, save space and reduce costs.
