Description

Environmental protection furnace cupola
Technical field
The present invention relates to a kind of furnace cupola, be specifically related to a kind of environmental protection furnace cupola.
Background technology
Cast iron smelting is one of important step obtaining premium casting.The equipment of cast iron smelting has tilting cupola, three joint stove, electric furnace (electric arc furnaces or electric induction furnace), furnace cupolas etc.Wherein, furnace cupola is most widely used, ironcasting total output more than 90%, this is because the feature of cupola melting to be equipment simple, easy to operate, production efficiency is high, can continuous seepage, cost low.Although it is easy that the molten iron temperature of furnace cupola and Composition Control are not so good as electric furnace, it can meet the production requirement of general ironcasting substantially, and thus furnace cupola remains the capital equipment of cast iron smelting at present.Furnace cupola is a kind of cylindrical shape shaft furnace, except being mainly used in iron casting production, also can in order to coordinate pneumatic steelmaking, and being also used for copper sometimes, because of furnace roof opening upwards, therefore is called furnace cupola.
Current existing furnace cupola is in fusion process, and the high-temp waste gas of generation upwards flows out body of heater from furnace roof opening along the inner chamber of body of heater, and wherein some is that directly discharge passes into air, makes to cast place surrounding enviroment and is in the misty state of ash throughout the year.And its coke ratio is high, it is large to pollute, be the rich and influential family of power consumption and blowdown, this, more and more high current of environmental requirement, seriously constrains development and the growth of foundry industry.And, high-temp waste gas is not except processing except clean dust completely, and also containing the pernicious gas such as SO2, dust, this is not only to environment, and infringement casting place operating personnel's is healthy, this has become casting industry hard nut to crack urgently to be resolved hurrily for a long time.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved there is provided a kind of simple and reasonable for structure, effectively removes sulfur dioxide in flue gas and dust, the environmental protection furnace cupola of energy-conserving and environment-protective.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: environmental protection furnace cupola, comprise: furnace cupola body, the outlet flue of described furnace cupola body is provided with flue gas processing device, described flue gas processing device is primarily of collection smoke box, pipe and water distributor are formed, described collection smoke box is arranged in the smoke box outlet of furnace cupola body, the top circumference of described collection smoke box is evenly equipped with multiple pipe, the bottom of described pipe extends to the lower inside of collection smoke box, the top center of collection smoke box is provided with water distributor, described water distributor be circumferentially provided with multiple outlet pipe, the delivery port of each outlet pipe is separately positioned in pipe, the delivery port of described outlet pipe is provided with atomizer, feed pipe is provided with in described water distributor, each outlet pipe is all connected with feed pipe, the outlet flue of described furnace cupola body enters mouth higher than pipe, delivery port is had bottom described collection smoke box.
Preferably, described collection smoke box top has overhaul of the equipments mouth.
Structure of the present invention is simple, easy to use, by installing collection smoke box on furnace cupola additional, carries out purification filtering process to flue gas, removes the sulfur dioxide in flue gas and dust, effectively reduces the discharge of pernicious gas, protection of the environment, and processing cost is low simultaneously, is easy to install.
Accompanying drawing explanation
Fig. 1 is the structural representation of environmental protection furnace cupola of the present invention.
Fig. 2 is the top view of Fig. 1.
In figure: 1 is furnace cupola body, 2 is collection smoke box, and 3 is pipe, and 4 is water distributor, and 5 is outlet pipe, and 6 is atomizer, and 7 is feed pipe, and 8 is delivery port, and 9 is overhaul of the equipments mouth.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment that the present invention does is described further.
As Fig. 1, shown in Fig. 2, environmental protection furnace cupola, comprise: furnace cupola body 1, the outlet flue of furnace cupola body 1 is provided with flue gas processing device, flue gas processing device is primarily of collection smoke box 2, pipe 3 and water distributor 4 are formed, collection smoke box 2 is arranged in the smoke box outlet of furnace cupola body 1, the top circumference of collection smoke box 2 is evenly equipped with multiple pipe 3, the bottom of pipe 3 extends to the lower inside of collection smoke box 2, with the gap leaving 10-20cm bottom collection smoke box 2, the top center of collection smoke box 2 is provided with water distributor 4, water distributor 4 be circumferentially provided with multiple outlet pipe 5, the delivery port of each outlet pipe 5 is separately positioned in pipe 3, the delivery port of outlet pipe 5 is provided with atomizer 6, feed pipe 7 is provided with in water distributor 4, each outlet pipe 5 is all connected with feed pipe 7, the outlet flue of furnace cupola body 1 enters mouth higher than pipe 3, mainly for anti-sealing enters in furnace cupola, and flue gas can be kept to flow out in pipe 3, delivery port 8 is had bottom collection smoke box 2, delivery port 8 is connected with pollution discharge pond for blowdown, conveniently carry out subsequent treatment, collection smoke box 2 top has overhaul of the equipments mouth 9, conveniently overhaul at any time.
When the present invention specifically uses, flue gas in furnace cupola enters in collection smoke box 2 through outlet flue, and enter through the gap between bottom pipe 3 and smoke collection pipe 2 after pipe 3 and discharge, water distributor 4 conveniently can carry out water pipe layout, feed pipe 7 supplies water, spray water to pipe 3 through outlet pipe 5, atomizer 6, the harmful substances such as the sulfur dioxide in removal flue gas and dust, water flows in collection smoke box 2, be discharged into pollution discharge pond through delivery port 8 and carry out subsequent treatment, use simple, convenient, processing cost is low.
