Description

A kind of coke dry quenching furnace air leading-in conduit of preheated air
Technical field
The utility model relates to a kind of dry coke quenching auxiliary, especially a kind of coke dry quenching furnace air leading-in conduit.
Background technique
Dry Quenching Technology is the energy-saving and environment-friendly promotional technique of coking industry, i.e. dry coke quenching is by inert circulating air The cooling red coke of body, recycling heat produce vapor, the vapor of generation can be used to generate electricity or pressure and temperature reducing after be incorporated to plant area's steaming Steam pipe net is used for other workshops, avoids a series of environmental pollutions of coke wet quenching bring.The low-temperature circulating gas of cooling coke, Temperature is increased to 900 ~ 960 DEG C after coke dry quenching furnace cooling section and red burnt heat convection, annular of the high temperature circulation gas from coke dry quenching furnace Air duct comes out, and boiler is entered after disposable dust remover separates coarse granule coke powder and carries out heat exchange, boiler generates steam, temperature drop To about 160 ~ 180 DEG C of recyclegas again through the further separate fine particles coke powder of secondary filter, sent after being pressurizeed by circulating fan Enter feed-water preheating system and be cooled to about 130 DEG C, enters back into coke dry quenching furnace and be recycled.
In dry coke quenching operation, for the combustible component concentration in control loop gas in explosion limit hereinafter, oriented cycles gas Supplement nitrogen dilution combustible gas component falls two kinds of approach of fuel gas with air burning is imported in system system, due to supplementing nitrogen Method is there are the big disadvantages such as low with generated energy of at high cost, thermal loss, normal to produce except seldom using this method in the case of special producing Shi Jing is frequently with importing air method.But air leading-in conduit imports air and coke dry quenching furnace annular cigarette after normal temperature air position and importing Flammable recyclegas in road or coke powder burning discharge a large amount of heat cause coke dry quenching furnace ring-shaped flue furnace wall regular by To the rapid drawdown that rises sharply repeatedly of temperature, its masonry is made to generate damage under the action of the thermal stress being subject to, deformation, even collapse, Shorten the service life of coke dry quenching furnace and increases production cost.
Utility model content
The purpose of the utility model is to provide a kind of simple process, quickly adjust recyclegas system in imflammable gas at Divide, security performance is high, reduce coke dry quenching furnace coke burning, the coke dry quenching furnace air for the preheated air for improving coke dry quenching furnace service life imports Pipe.
The purpose of this utility model is achieved in that a kind of coke dry quenching furnace air leading-in conduit of preheated air, it is characterized in that: Including at least coke dry quenching furnace, air leading-in conduit road, flow control valve, heat exchanger, the inlet end in the air leading-in conduit road passes through Pipe fitting valve is communicated with atmosphere, and the ring-shaped flue connection of outlet side and coke dry quenching furnace, the inlet end and air in air leading-in conduit road is led The outlet side for entering pipeline is sequentially connected flow control valve and heat exchanger by pipe fitting valve;The air leading-in conduit road inlet end For bell shape, and detailed catalogue stainless (steel) wire is connected in port;The air leading-in conduit road outlet side passes through pipe fitting valve Branch pipe is imported equipped at least 2 air to connect with coke dry quenching furnace ring-shaped flue and disposable dust remover respectively.
The heat exchanger uses finned heat exchanger.
Purification device and section are connected in turn by pipe fitting valve on air leading-in conduit road before the flow control valve Flow device.
The air leading-in conduit road of the flow control valve and heat exchanger both ends is equipped with by-pass line, on by-pass line Equipped with flow control valve by-passing valve.
Nitrogen is connected with by pipe fitting valve on air leading-in conduit road between the throttling set and purification device to mend Pipeline is filled, nitrogen supplement pipeline is equipped with nitrogen and is blown into valve.
The utility model has the advantages that
1, branch pipe is imported by the heat exchanger of setting and air, not only increases the air themperature for importing dry quenching system, And it is only adjusted to respectively in coke dry quenching furnace ring-shaped flue and disposable dust remover in coke dry quenching furnace ring-shaped flue importing air original Air is imported, air capacity is imported and does not increase and increase and import air position, so that can in the air and high temperature circulation gas that import Combustion property gas is easier to be uniformly mixed completely burned, can quickly adjust imflammable gas ingredient in control loop gas system, together When avoid burning concentrate on a certain position cause this regional temperature rise violently masonry damage so that coke dry quenching furnace annular furnace wall is imported Air and import into air and ring-shaped flue in imflammable gas recyclegas or coke powder burning discharge a large amount of heat and make It is reduced at the influence that temperature rises violently, the temperature fluctuation of masonry reduces, and reduces thermal stress to the damage effect of masonry, improves dry Put out the service life of furnace.
2, enter dry coke quenching with the outside air of importing by the purification device removing being arranged on air leading-in conduit road to follow The impurity such as dust, grease and moisture in ring gas system substantially avoid moisture in outside air and enter dry coke quenching circulation Water gas reaction occurs for gas system and high-temperature coke, reduces coke burning rate, while flammable gas in recyclegas system Body ingredient is easier to securely and reliably control, and reduces influence of the external environment variation to dry coke quenching normal production operation.
3, by-pass line, nitrogen supplement pipeline, the designs such as throttling set so that dry coke quenching auxiliary not only security performance improves, And process flow is also simple, is advantageously implemented dry coke quenching precision production operation management.
