Description
Technical field
The present invention relates to complex thermal coke heating system control field, relate in particular to a kind of exchange transmission gear of when rich gas and low-grade gas add thermal conversion, realizing remotely switching types of gas heated in coke oven.
Background technology
At present, the coke oven heating system Main Function is to carry and adjusting heating coal gas and air to pit kiln, and discharges the rear waste gas of burning.Rich gas refers to coke oven heating with the high coal gas of calorific value, such as coke-oven gas etc.Low-grade gas refers to that the coke oven heating is with the low coal gas of calorific value, such as blast furnace gas, producer gas and mixed gas etc.Because coke-oven gas is important high-grade fuel, the coke oven heating should be used coke-oven gas, multiplex low-grade gas with fuel as far as possible less.Steel Complex's coke-oven plant's coke oven generally adopts blast furnace (BF) gas heating, but blast furnace staying or can't supply blast furnace gas to coke oven when breaking down, need in the case to adopt the coke-oven gas heating, therefore modern coke oven generally adopts rich gas heating and low-grade gas to heat two cover systems.
Complex thermal coke adopts several twinflues, each twinflue comprises 2 flues, a flue enters heating gas and air (for upstream) in coke oven each twinflue of when heating, the two converges afterfire, the waste gas that produces after the burning is crossed over the hole by the flue top and is entered another flue in the twinflue (for downdraft), and waste gas enters flue and enters atmosphere through regenerator, waste gas exchange shutter again.Upstream and downdraft change once every 20～30 minutes air flow lines in each twinflue, upstream changes downdraft into, downdraft changes upstream into, and the waste gas of the coal gas of upstream and air and downdraft drives exchange transmission gear by existing hydraulic switch and regularly commutates.
When using rich gas such as coke-oven gas, because coke-oven gas does not need preheating, so coke-oven gas is directly sent into flue bottom, combustion chamber without the waste gas exchange shutter, converge burning with the air that enters via waste gas exchange shutter, regenerator, waste gas after the burning is crossed over the flue that the hole enters downdraft by the flue top, behind regenerator recovery sensible heat, enter atmosphere through waste gas exchange shutter, flue.
When using low-grade gas such as mixed gas, mixed gas is sent into the combustion chamber flue by waste gas exchange shutter, regenerator and is converged burning with the air that enters via waste gas exchange shutter, regenerator, the waste gas that produces after the burning enters atmosphere, and its approach is identical when burning coke-oven gas.
The path that enters body of heater because of rich gas and low-grade gas is different, and when therefore burning rich gas, gas regenerator air door and the air regenerator air door of waste gas exchange shutter all will be opened into the air of burning usefulness.When burning low-grade gas, the gas regenerator air door of waste gas exchange shutter will be closed, and the air regenerator air door will be opened into the air of burning usefulness.Rich gas during with low-grade gas perfect combustion needed air capacity different, the air-admitting surface of air regenerator air door is different when therefore burning rich gas with low-grade gas.
Exchange transmission gear comprises waste gas exchange and coke-oven gas exchange at present, rich gas adopts cock control, low-grade gas adopts the coal gas thallium control in the waste gas exchange shutter, and the switching of the gas regenerator air door in the waste gas exchange shutter, air regenerator air door, coal gas thallium all links with the switching of waste gas thallium.
In the production when transferred to low-grade gas when heating by rich gas, the link rod of interlock gas regenerator air door on the waste gas exchange shutter need to be removed one by one, make gas regenerator air door Close All, link rod with interlock coal gas thallium on the waste gas exchange shutter joins one by one again, the coal gas thallium can with the switching interlock of waste gas thallium, also be needed manually to be changed air regenerator air door air-admitting surface into burn low-grade gas air-admitting surface by the air-admitting surface of burning rich gas.When being transferred to the rich gas heating by low-grade gas, the link rod of interlock gas regenerator air door on the waste gas exchange shutter need to be joined one by one, allow the gas regenerator air door link with the switching of waste gas thallium, link rod with interlock coal gas thallium on the waste gas exchange shutter removes one by one again, make coal gas thallium Close All, also need manually air regenerator air door air-admitting surface to be changed into by the air-admitting surface of burning low-grade gas the air-admitting surface of rich gas.Workload is large during replacing, and the workman operates trifling, and is numerous and diverse, and changing a kinds of gas needs more than 20 people to work simultaneously, needs the time about half a day.
Summary of the invention
