Abstract
An electric furnace settling chamber comprises a settling chamber inlet connected with an electric furnace dust exhaust opening and a settling chamber outlet provided with a heat preservation pipe. Two or more alloy baking chambers are further formed in the electric furnace settling chamber. Each alloy baking chamber comprises an inlet funnel extending out of the settling chamber, a barking barrel connected with the corresponding inlet funnel, and an opening mechanism provided with a discharging valve between the opening mechanism and the barking barrel. The electric furnace settling chamber has the advantages of being good in waste-heat utilization effect and high in waste-heat utilization efficiency, thereby achieving the purposes of energy conservation and emission reduction.
Description
Technical field
The utility model relates to steelmaking technical field, especially relates to a kind of electric furnace expansion chamber.
Background technology
Electric furnace expansion chamber is that one is removed graininess dust in flue gas, simultaneously by partially combusted CO equipment.Expansion chamber generally comprises the structures such as gas approach, exhanst gas outlet and water-cooled flue, after the processing of expansion chamber, can reduce dust and the CO content in flue gas and reduce the temperature of flue gas.If application number is disclosed expansion chamber in No. 200910191168.4 patents of invention, this expansion chamber comprises smoke inlet, air inlet and exhaust opening, smoke inlet spatial placement Heat Storing Wall just above in combustion chamber, make flue gas first enter Heat Storing Wall from porch, in Heat Storing Wall, arrange grain bed, mixed cigarette angle is set on the side wall under electric furnace flue gas exhaust opening, water-cooled heat exchanger tube is set on the interior wall of combustion chamber.This invention is the object that reaches regulation and control flue-gas temperature by Heat Storing Wall.But this invention does not still solve the problem that fume afterheat utilizes.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing in prior art, a kind of electric furnace expansion chamber is provided, in this expansion chamber, be furnished with several alloy baking chambers, Baking out by the waste heat of flue gas for alloy, thereby reach the object of energy-saving and emission-reduction, the technical scheme adopting is: a kind of electric furnace expansion chamber, described expansion chamber is provided with the expansion chamber import being connected with electric furnace dust-exhausting port and the expansion chamber that is provided with insulating tube outlet, it is characterized in that: in expansion chamber, be also provided with plural alloy baking chamber, described alloy baking chamber comprises the buccal funnel that enters stretching out outside expansion chamber, with the baking cylindrical shell that enters buccal funnel and be connected, and between baking cylindrical shell, be provided with the opener of discharge valve.
Technical characterictic of the present utility model also has: the agent structure of expansion chamber is three layers structure, and outermost layer is steel concrete layer, and intermediate layer is alumina silicate fiber felt, and inner liner is refractory brick.
Technical characterictic of the present utility model also has: in expansion chamber, be provided with 5 alloy baking chambers, 5 baking vessel are divided into two and arrange and put, and adjacent baking vessel is not on same row.
Technical characterictic of the present utility model also has: the centre-to-centre spacing of adjacent two rows' alloy baking chamber is 400-600mm.
Technical characterictic of the present utility model also has: on expansion chamber, be provided with access door, described access door skin is steel plate, has refractory material at inner steel lining.
Technical characterictic of the present utility model also has: explosion-proof valve is also housed in described expansion chamber.
The beneficial effects of the utility model are: the utility model, in order to realize the object of UTILIZATION OF VESIDUAL HEAT IN in electric furnace expansion chamber, is provided with several alloy baking chambers in expansion chamber; Consider the effect of UTILIZATION OF VESIDUAL HEAT IN, adopt two row's formula layouts that alloy baking chamber is installed, and adjacent baking vessel is not positioned on same row; Fire when preventing that CO content is higher, in expansion chamber, be provided with explosion-proof valve.The utlity model has that exhaust heat utilization effect is good, the advantage of UTILIZATION OF VESIDUAL HEAT IN efficiency height, reached the object of energy-saving and emission-reduction.
