Description
Technical field
The present invention relates to burnt during a kind of a kind of coke oven basement gas heating system, specifically gas switch maintenance
The exchange method of stove basement gas heating system.
Background technology
Coke oven is also known as coke oven, refer to for by coking coal isolation air strengthen hot a cycle time production metallurgy Jiao or
Foundry Coke produces a kind of stove equipment of coke-stove gas simultaneously.Modern coke oven sorting technique is a lot, is divided into top by the mode of coalingging
Fill coke oven and side dress coke oven；It is divided into complex thermal coke and heat type one coke oven with kinds of gas by heating；By air and heating coal
The infeed mode of gas is divided into side entering type coke oven and underjet coke oven；It is divided into top adjustable type coke oven and bottom by air-flow regulative mode
Adjustable type coke oven；It is divided into multistage heating formula coke oven, height lamp head type coke oven, waste gas circulation formula coke oven by flaming mode is elongated.
Coke oven basement is located at coke oven bottom, for adjust, change heating gas equipment (as plus-minus cock, exchange rotary plug,
Orifice plate and nozzle etc.) space.
Coal gas switching equipment is used for the power-equipment and transmission mechanism for switching coke oven heating system gas flow direction, including
Interchanger and exchange transmission gear.
Interchanger is the dynamic power machine for driving each transmission tie rod to swap.
Coke oven basement gas heating system needs periodically to swap and (exchange once every about 20-30 minutes), at present
The switching equipment that heating gas is exchanged periodically is substantially hydraulic switch now, mainly by hydraulic station, hydraulic cylinder, pipeline and phase
The electrical apparatus control equipment composition of pass.
Hydraulic station is supporting to set two sets of pumps of the using and the reserved and two sets of valve groups, and generally fault rate is at a fairly low, but also has
When needing maintenance, whenever hydraulic station is overhauled, generally swapped with chain block.The operation sequence that chain block exchanges
As shown in Figure 1：Chain block is hung up properly 1. being connected in advance in concrete column 3 of the A points with B points corresponding thereto using steel wire rope,
It is and exceptionally straight；2. the direction exchanged as needed when exchanging, the tight chain block pine of a chain block.
4 people's operations, about 6-8 minutes swap time (when blast furnace gas exchanges) are at least needed during exchange, and is normally made
Exchanged and be no more than 20 seconds with interchanger, so exchanged using chain block has large effect to the normal heating of coke oven, simultaneously
Swap time grows the chance that can also increase gas leak, and the safety of operating personnel is also had a certain impact.
The content of the invention
There are large effect, increase coal in the presence of the normal heating to coke oven for using chain block to exchange in the prior art
The deficiencies of chance of gas leakage, the technical problem to be solved in the present invention is to provide a kind of manipulation strength that can substantially reduce people not
The exchange method of coke oven basement gas heating system when influenceing heating and the gas switch of gas leak will not be caused to overhaul.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
The exchange method of coke oven basement gas heating system when a kind of gas switch of the present invention overhauls, using using electricity
Hydrodynamic cylinder pressure swaps, and comprises the following steps：
It is simultaneously that steel wire rope is exceptionally straight that the method exchanged by chain block hangs up properly cucurbit；
Pull down waste gas hydraulic cylinder both ends and waste gas stroke coupling part；
Waste gas hydraulic cylinder and electrohydraulic cylinder oil pipe are connected, electricity is connect and carries out empty examination；
Position of Hydraulic Cylinder is got to the position consistent with waste gas stroke after sky examination is normal, connects waste gas stroke and electronic liquid
The joint of cylinder pressure；
Come up chain block, and stroke change is paid attention to during release；
According to needs are exchanged, swapped using electrohydraulic cylinder.
According to coke oven model, hole count is different and interchanger load is different, selects the electric hydaulic of interim alternate switch
Cylinder model matches with scene needs.
Electrohydraulic cylinder is one or more, and multiple electrohydraulic cylinders need to be used in series according to load.
The invention has the advantages that and advantage：
1. the inventive method is to substitute chain block using electrohydraulic cylinder when exchanging machine overhauling to swap, need to only press
Push button operates, and swap time is close with being swapped using interchanger, can substantially reduce the manipulation strength of people, together
When can also meet the requirement of coke oven heating system, i.e., do not influence heating and gas leak will not be caused.
Brief description of the drawings
Exchange method illustrates when Fig. 1 overhauls for gas switch in the prior art.
Wherein, 1 is waste gas hydraulic cylinder, and 2 be tie rod stroke, and 3 be concrete column.
Embodiment
With reference to Figure of description, the present invention is further elaborated.
The exchange method of coke oven basement gas heating system during gas switch maintenance of the present invention, applied to waste gas circulation
The exchange of basement gas heating system of the formula coke oven when exchanging machine overhauling, is swapped using electrohydraulic cylinder, including with
Lower step：
It is simultaneously that steel wire rope is exceptionally straight that the method exchanged by chain block hangs up properly cucurbit；
Pull down waste gas hydraulic cylinder both ends and waste gas stroke coupling part；
Waste gas hydraulic cylinder and electrohydraulic cylinder oil pipe are connected, electricity is connect and carries out empty examination；
Position of Hydraulic Cylinder is got to the position consistent with waste gas stroke after sky examination is normal, connects waste gas stroke and electronic liquid
The joint of cylinder pressure；
Come up chain block, and stroke change is paid attention to during release；
According to needs are exchanged, swapped using electrohydraulic cylinder.
The inventive method is when coke oven switching equipment exchanges machine overhauling, substitutes chain block using electrohydraulic cylinder and carries out
Exchange.According to coke oven model, hole count is different and interchanger load is different, selects the electrohydraulic cylinder type of interim alternate switch
Number with scene needs match.Electrohydraulic cylinder is one or more, and multiple electrohydraulic cylinders need to be used in series according to load.
The present invention substitutes chain block using electrohydraulic cylinder and swapped, and need to only press a button operation, and exchange
Time is close with being swapped using interchanger, can substantially reduce the manipulation strength of people, while can also meet coke oven heating system
The requirement of degree, i.e., gas leak will not also be caused by not influenceing heating.
