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 fields, are related to a kind of for stablizing the method for coke oven collecting main pressure.
Background technique
In recent years, the domestic capacity coke oven for having built a large amount of 6 meters or even 7 meters or more successively, coal gas guiding system are
Two sections of gas collecting tubes, gas-blowing engine are adjusted the speed automatically using fluid coupling, with stabilizing blower suction, use turnover panel on gas collecting tube
It automatically adjusts and stablizes collecting main pressure.For these coke ovens after operation of going into operation, generally existing coke oven collecting main pressure fluctuates big
Often there is hyperpressure and the positions such as fire door is caused to smolder kindling even raw coke oven gas release, or extremely low pressure coke oven occurs in problem
Negative pressure causes furnace body blowby, not only seriously pollutes environment, loses resource, and very big to coking furnace shaft harm, seriously affects coke
Furnace service life.For this purpose, domestic many factories and research unit have carried out a large amount of research and probe, all do not solve ideally
This problem.
Analyze reason, the technique mainly has the following two problems:
1, air blower fluid coupling adjusts the speed lag automatically, causes air blower suction force fluctuation range big, so that on gas collecting tube
Pressure, which adjusts machine, cannot achieve fine tuning to stablize collecting main pressure.Simultaneously as air blower suction force control lag also result in its with
There are couplings for automatic regulating system on gas collecting tube, interfere with each other.
2, there is also couplings for segmented collecting main pressure adjusting machine itself, in the case where air blower suction force fluctuation is big
It is easy to happen " surge " phenomenon, is interfered with each other；
Solving this very corn of a subject is stabilizing blower suction, it is ensured that coal gas exports overall situation pressure and stablizes, and is gas collection
Pipe pressure adjusting creates good conditions.
Summary of the invention
The present invention is intended to provide one kind, which is able to achieve, quickly adjusts air blower suction force, to maintain air blower suction force to stablize, in turn
Machine, which is adjusted, for collecting main pressure creates stable service condition, the final method for realizing that coke oven collecting main pressure is stable.
For this purpose, this invention takes following technical solutions:
(1) increase turnover panel automatic regulating system on gas piping before gas-blowing engine entrance, and turnover panel is automatically adjusted
It interlocks and runs with air blower suction force, while releasing the interlock connection of coupler revolving speed and air blower suction force；
(2) reasonable suction force range is in 1500 ± 200Pa before demarcating primary cooler, and collecting main pressure adjusts machine fortune within this range
Row is stablized；
(3) the reasonable working range of turnover panel is 30%~70% before demarcating air blower, and within this range, turnover panel adjusts the cleverest
It is quick；
(4) it takes before air blower based on turnover panel automatic adjustment, is aided with adjustment air blower fluid coupling revolving speed, cycle tube valve
The suction method of adjustment of door and blower inlet valve opening, is tuned into fixation, air blast for air blower fluid coupling revolving speed first
Machine and gas collecting tube turnover panel adjust machine and are tuned into automatically, and turnover panel aperture is controlled 30%~70%；Then according to the change of coal resource
Change, manually adjust air blower fluid coupling revolving speed, or further manually adjust circulation pipe valve, blower inlet valve is opened
Degree.Concrete operations main points press following corresponding relationship:
The invention has the benefit that
Present invention can ensure that the stabilization of air blower suction force, is improved extremely in the qualification rate of 1500 ± 200Pa by original 65%
95% or more, collecting main pressure is obviously improved, in the range of 160 ± 40Pa qualification rate by original 64% be increased to 96% with
On.There is no crossing coal gas diffusion accident since coming into operation, kindling is smoldered and furnace body blowby situation is eliminated, environmental quality
It is obviously improved, the damage of furnace retaining ironware and equipment caused by being greatly reduced every year because of collecting main pressure fluctuation greatly, reduction spare part,
Cost of equipment and byproduct loss.
Detailed description of the invention
Fig. 1 is that air blower suction force adjusts process schematic representation.
Specific embodiment
The present invention is mainly that suction is constantly close to setting value before adjusting air blower 1 by controlling the aperture of turnover panel 3, with this
To reach the stabilization of air blower suction force and collecting main pressure.Its method particularly includes:
1, increase a set of 3 automatic regulating system of turnover panel on gas piping before 1 entrance of gas-blowing engine, meanwhile, by turnover panel 3
Automatic regulating system and air blower suction force control point 6, which are formed, to be interlocked.
2, the calibration reasonable suction force range of air blower 1 is in 1500 ± 200Pa.
3, the reasonable working range that turnover panel 3 is adjusted before calibration air blower 1 is 30%~70%.
4, it takes before air blower based on the automatic adjustment of turnover panel 3, is aided with adjustment 2 revolving speed of air blower fluid coupling, circulation pipe
The suction method of adjustment of 4 aperture of valve 5 and blower inlet valve, is tuned into fixation for 2 revolving speed of air blower fluid coupling first,
Air blower 1 and gas collecting tube turnover panel adjust machine and are tuned into automatically, and 3 aperture of turnover panel is controlled 30%~70%；Then occurred according to coal gas
The variation of amount manually adjusts 2 revolving speed of air blower fluid coupling, or further manually adjusts circulation pipe valve 5, blower inlet
4 aperture of valve.Embodiment concrete operations main points press following corresponding relationship:
