Abstract
The invention provides a method for stabilizing the pressure of a gas collecting pipe of a coke oven, which is characterized in that a set of automatic flap adjusting system is added in a gas pipeline in front of the inlet of a gas blower, and the automatic flap adjusting system and a suction control point in front of the blower are interlocked; the reasonable suction range before the primary cooler is calibrated to be 1500 +/-200 Pa; the reasonable adjusting working range of the front turning plate of the calibration blower is 30-70%; the rotating speed of the hydraulic coupler of the air blower and the turning plate are adjusted to be automatic, and the opening degree of the turning plate is controlled to be 30-70%; according to the change of the gas generation amount, the rotating speed of the hydraulic coupler of the blower is manually adjusted, then the number of turns of the opening of the valve of the circulating pipe is manually adjusted, and finally the opening of the inlet valve of the blower is manually adjusted. The invention can ensure the stability of the suction before the primary cooler, the qualification rate of 1500 +/-200 Pa is more than 95 percent, the qualification rate in the range of 160 +/-40 Pa reaches more than 96 percent, the damage of furnace protecting iron pieces and equipment caused by large pressure fluctuation of the gas collecting pipe is greatly reduced, and the loss of byproducts is avoided.
Description
Technical field
The invention belongs to coke making process technical field, it is related to a kind of method for stablizing coke oven collecting main pressure.
Background technology
In recent years, the domestic capacity coke oven for having built substantial amounts of 6 meters or even more than 7 meters successively, coal gas guiding system is two sections
Discharge, gas-blowing engine uses fluid coupling automatic speed regulation, automatic using turnover panel on discharge with stabilizing blower suction
Regulation stabilization collecting main pressure.After operation of going into operation, generally existing coke oven collecting main pressure fluctuates big problem these coke ovens,
Hyperpressure often occur causes the smolder even raw coke oven gas that catches fire of the positions such as fire door to diffuse, or extremely low pressure coke oven negative pressure occurs, makes
Into body of heater blowby, not only severe contamination environment, loses resource, and very big to coking furnace shaft harm, has a strong impact on coke oven and uses
Life-span.Therefore, domestic many factories and research unit have carried out substantial amounts of research and probe, this is not all solved ideally and is asked
Topic.
Analysis reason, the technique is primarily present following two problems：
1st, the automatic speed regulation of air blower fluid coupling is delayed, causes air blower suction force fluctuation range big so that pressure is adjusted on discharge
Section machine cannot realize fine setting to stablize collecting main pressure.Simultaneously as air blower suction force control lag also result in its with discharge on
Be present coupling in automatic regulating system, interfere.
2nd, segmented collecting main pressure regulation machine itself there is also coupling, easily be sent out in the case where air blower suction force fluctuation is big
Raw " surge " phenomenon, interferes；
It is stabilizing blower suction to solve this very corn of a subject, it is ensured that coal gas exports overall situation pressure stability, is collecting main pressure
Regulation creates good conditions.
The content of the invention
The present invention is intended to provide one kind can realize quick regulation air blower suction force, to maintain air blower suction force stabilization, and then it is gas collection
Pipe pressure regulation machine creates the service condition of stabilization, the method for finally realizing coke oven collecting main pressure stabilization.
It is up to this purpose, this invention takes following technical solution：
(1) increase turnover panel automatic regulating system on gas piping before gas-blowing engine entrance, and turnover panel is automatically adjusted and air blast
Machine suction interlocking operation, while releasing the interlock connection of coupler rotating speed and air blower suction force；
(2), in 1500 ± 200Pa, the operation of collecting main pressure regulation machine is steady within this range for reasonable suction force range before demarcating primary cooler
It is fixed；
(3), 30%~70%, within this range, turnover panel regulation is the sensitiveest for the reasonable working range of turnover panel before demarcating air blower；
(4) take based on turnover panel before air blower automatically adjusts, be aided with adjustment air blower fluid coupling rotating speed, circulation pipe valve and
The suction method of adjustment of blower inlet valve opening, is tuned into fixation, air blower and collection by air blower fluid coupling rotating speed first
Tracheae turnover panel regulation machine is tuned into automatically, and turnover panel aperture is controlled 30%~70%；Then according to the change of coal resource, adjust manually
Section air blower fluid coupling rotating speed, or circulation pipe valve, blower inlet valve opening are further adjusted manually.Concrete operations
Main points press following corresponding relation：
Beneficial effects of the present invention are：
Present invention can ensure that the stabilization of air blower suction force, is improved to more than 95% in the qualification rate of 1500 ± 200Pa by original 65%,
Collecting main pressure is obviously improved, and qualification rate brings up to more than 96% by original 64% in the range of 160 ± 40Pa.Come into operation
Since there is no coal gas diffusion accident, smolder and catch fire and body of heater blowby situation is eliminated, environmental quality is obviously improved, often
The damage of the furnace retaining ironware and equipment caused by collecting main pressure fluctuation is big can be greatly reduced year, spare part, cost of equipment and pair is reduced
Product loses.
Brief description of the drawings
Fig. 1 is air blower suction force regulation process schematic representation.
Specific embodiment
Suction is constantly close to setting value before the present invention mainly adjusts air blower 1 by controlling the aperture of turnover panel 3, is reached with this
To air blower suction force and the stabilization of collecting main pressure.Its specific method is：
1st, the automatic regulating system of a set of turnover panel 3 is increased on gas piping before the entrance of gas-blowing engine 1, meanwhile, by turnover panel 3 certainly
Dynamic regulating system forms interlocking with air blower suction force control point 6.
2nd, the reasonable suction force range of air blower 1 is demarcated in 1500 ± 200Pa.
3rd, the reasonable working range that turnover panel 3 is adjusted before demarcation air blower 1 is 30%~70%.
4th, take based on turnover panel 3 before air blower automatically adjusts, be aided with the rotating speed of adjustment air blower fluid coupling 2, circulation pipe valve
5 and the suction method of adjustment of the aperture of blower inlet valve 4, the rotating speed of air blower fluid coupling 2 is tuned into fixation first, drum
Blower fan 1 and discharge turnover panel regulation machine are tuned into automatically, and the aperture of turnover panel 3 is controlled 30%~70%；Then according to coal resource
Change, the manually rotating speed of regulation air blower fluid coupling 2, or further manual regulation circulation pipe valve 5, blower inlet valve
4 apertures of door.Embodiment concrete operations main points press following corresponding relation：
