Description
Technical field
The utility model belongs to coke oven gas system field, and specifically a kind of lower spray coke oven firing tunnel in coking furnace exchanges system
System.
Background technology
Modern coke oven has polytype, be broadly divided into twinflue formula, two points of fire-path types and on across flue formula.Duplex
Fire-path type refers to ascending air quirk and down current quirk pair-wise combination, and whole combustion chamber is made of some groups of twinflues.
For full stove arrange full combustion chamber heating for, rise and fall air-flow is interlaced arrangement, at interval of after an exchange cycle by
Commutation is completed by oil pump, hydraulic cylinder, connecting rod.Coke-stove gas exchange in, any coke oven heating system be all by turn out the gas,
Three empty exhaust gas, turn on the gas steps completion exchanges are exchanged, its operation principle is：When exchanging beginning, coal gas pump start, coal gas
Cylinder is started to work, and coal gas swaps, and after coal gas exchanges to centre position, coal gas cylinder is stopped, and exhaust gas cylinder is started to work,
After treating that empty, exhaust gas exchanges, coal gas cylinder continues to exchange to be completed until exchanging.It is but main during above exchange system
There are following items shortcoming：Gas heating system frequent exchange, exchanges the increase of cock frictional resistance, causes cock gas leak phenomenon
Increase, there are security risk.Periodically cock is exchanged to full stove to clean, expend a part of human and material resources, financial resources；In reality
In, exchange 2 time/month of cock cleaning frequency, every time 6 person/days of completions of cleaning, whens special circumstances need to increase the cleaning frequency；And exchange
Cock, which exists, blows out phenomenon, and more serious vibrations are tight on furnace body and there is certain influence in the service life.
Utility model content
For solve to exchange cock gas leakage in twinflue formula coal gas exchange system now and blow out situation increase, cock it is clear
The problem of taking time and effort is washed, the utility model provides a kind of lower spray coke oven firing tunnel in coking furnace exchange system.
The utility model is realized by following technical proposals.
The lower spray coke oven firing tunnel in coking furnace exchange system of one kind, including the gas pipe of conveying coal gas and some transverse tubes to transverse direction,
It is characterized in that gas pipe connects two supervisors, two supervisor front ends are equipped with motor-driven valve, and each pair transverse tube passes through two branch pipes point
Lian Tong not two supervisors；Each branch pipe is equipped with orifice plate and orifice plate box from top to bottom, and some flues are evenly equipped with above every transverse tube.
The lower spray coke oven firing tunnel in coking furnace exchange system, wherein, the branch pipe is vertical pipeline.
The lower spray coke oven firing tunnel in coking furnace exchange system, wherein, the branch pipe lower end is equipped with safety valve.
The beneficial effects of the utility model are：1st, change original by exchanging cock change rising, the commutation of down current
Pattern, only controls commutation process by two groups of electric control valves, can effectively reduce the exceeded frequency of nitric oxide, reduces carbon monoxide
Concentration；2nd, cock can be effectively eliminated and blow out hard nut to crack with gas leakage, prevent security risk, ensure safety in production, and one
Determine the service life of increase furnace body in degree；3 while work staff labor intensity is reduced, reduce cleaning, maintenance cost, carry
High efficiency.
Brief description of the drawings
Fig. 1 is the system structure diagram of the utility model.
In attached drawing：1st, gas pipe, 2, supervisor, 3, branch pipe, 4, transverse tube, 5, motor-driven valve, 6, orifice plate, 7, orifice plate box, 8, vertical fire
Road, 9, safety valve.
Embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in drawings, one kind is lower sprays coke oven firing tunnel in coking furnace exchange system, including the coal gas of coal gas is conveyed into coke oven
Pipe 1 and some to laterally disposed transverse tube 4, gas pipe 1 connects two supervisors 2, and two 2 front ends of supervisor are equipped with motor-driven valve 5, often
Two supervisors 2 are respectively communicated with by two vertical branch pipes 3 to transverse tube 4；Every branch pipe 3 is equipped with safety valve 9, hole from top to bottom
Plate 6 and orifice plate box 7, the every top of transverse tube 4 are evenly equipped with some flues 8.
Coke oven firing tunnel in coking furnace exchange system is sprayed under the utility model, every pipeline is by being located at supervisor two of 2 head ends
Motor-driven valve 5 controls, and motor-driven valve 5 controls the break-make of every supervisor 2, while controls the break-make of whole each pair transverse tube 4, completes to close
Coal gas, the exchange for exchanging empty three exhaust gas, turn on the gas steps, in an exchange process, only need to control two motor-driven valves 5 to distinguish
Switch is once, so that it may realizes a commutation process, operating principle is simple, can reduce by one produced in multiple plus-minus cock work
Concentration of carbon is aoxidized, while is only controlled by two motor-driven valves 5, cock blows out the hard nut to crack with gas leakage, prevents security risk,
Ensure safety in production；Reduce the vibrations to furnace body, ensure the service life of furnace body；Staff can be reduced at the same time to original plus-minus
Cock cleaning, the labor intensity of maintenance, save production run cost and improve production efficiency.It is respectively provided with the lower end of each branch pipe 3
There is safety valve 9, can facilitate when indivedual transverse tubes 4 break down, first close the safety valve 9 under corresponding transverse tube 4, maintenance, replace
Corresponding component, does not interfere with normal production, improves production mobility and production efficiency.
