For heating heating gas and air in upward system, exchanged every set time (usual 20-30 minutes) heating system
Once, odd even quirk is alternately heated, and meets coke oven uniformly heating and the interior requirement reclaimed of waste gas residual heat body.
Coke oven heating produce close to 200 DEG C of hot waste gas by smoke stack emission, heating system is used as by chimney heat buoyancy
Power.In recent years, under the pressure of coking pollutant emission standard rising and the clean manufacturing requirement such as energy-saving, more than coke oven flue gas
The new technologies such as recuperation of heat, gas cleaning are continued to bring out, and usual mode is one flue gas outlet of increase, one on former coke oven flue
Individual flue gas intake, one of stop valve of centre increase, realizes that coke oven flue gas is drawn by former flue, through waste heat recovery or gas cleaning
After processing, former flue is returned again to, through former smoke stack emission.Newly-increased system must set up air-introduced machine and be increased newly in itself to overcome system
Resistance, is caused after newly-increased system, coke oven heating system power is become in order to which gravity-flow ventilation is combined with forced ventilation by gravity-flow ventilation
Mode, although air-introduced machine employ frequency control way, and because coke oven heating system exchanges frequent, exchange process experience stops supplying
Coal gas, stops supplying air, supplies air, supplies the great variety of coal gas, and swap time is short etc., causes coke oven flue suction to fluctuate
Greatly.
The content of the invention
The purpose of this utility model is to design a kind of coke oven flue suction equalization system, can under various conditions, coke oven
Flue suction force can be stablized in a certain controllable scope, be that coke oven normal heating and normal exchange provide effective, safety
Motivational guarantee, it is ensured that coke oven increase newly system after, still be able to safe and reliable production, it is to avoid coke oven gas stream in the stove excessive variation is made
Into furnace body leakage amount increase, reduce coke oven heating system pollutant emission, keep the coke oven masonry of resistance to material tightness
To reach above-mentioned purpose, the technical solution of the utility model is：
A kind of coke oven flue suction equalization system, is installed on coke oven flue, and coke oven flue is included from coke oven chimney bottom cigarette

It is connected to the introducing pipeline of coke oven chimney smoke intake；It includes, and sets and draws at correspondence flue gas outlet in the introduction pipe
Outlet flap；Described be introduced into pipeline sets intake turnover panel at correspondence flue gas intake；And, the nearly desulfurization of introduction pipe takes off
At pin assembly import and it is described introducing pipeline be located at fan outlet between a connecting pipe is set, in the connecting pipe set adjust
Save turnover panel；Pressure tester, is arranged at the nearly flue gas outlet end of the flue gas introduction pipe；Controller, the pressure tester, regulation
Controller is electrically connected in turnover panel；Pressure tester feeds back to controller, and the aperture for adjusting turnover panel is instructed by controller.
It is preferred that, the regulation turnover panel is mechanical balance turnover panel；According to flue gas pressures and the action shape of regulation turnover panel
Condition, aperture regulation is realized to mechanical balance turnover panel.
It is preferred that, the regulation turnover panel parallel deployment 2-3 groups.
, can be when occurring flue gas pressures fluctuation by connecting pipe, the regulation turnover panel on regulation connecting pipe controls cigarette
Atmospheric pressure.
Regulation turnover panel on connecting pipe, by the pressure tester installed on outlet, feeds back to control system, by controlling
System command adjusts the aperture of turnover panel.
Mechanical balance turnover panel on connecting pipe；According to flue gas pressures and the running-active status of regulation turnover panel, to machinery
Formula balance turnover panel realizes automatic aperture regulation.
Resistance of the connecting pipe bore according to newly-increased system always between flue gas outlet and intake is damaged, by calculating,
Rock wool heat-preservation is configured outside pipeline.Flue gas outlet configures pressure-measuring system, and signal send the control system for automatically adjusting turnover panel, controls
System processed automatically adjusts the turnover panel on connecting pipe according to the suction change of flue gas outlet, automatically adjusts turnover panel parallel deployment 2-
3 groups, the adjustable range of increase regulation turnover panel.
Under normal circumstances, the frequency conversion fan for increasing system newly automatically adjusts frequency according to the change of flue suction force, meets flue
Suction control is required.In coke oven heating exchange process, because exhaust gas volumn is in short time generation great variety, turnover panel foundation is automatically adjusted
The change of flue suction force automatically adjusts aperture, balances two-phase flue gas, it is to avoid negative pressure is excessive.Coke oven limit produce load, increases system newly
Mechanical balance turnover panel action on the extreme conditions such as system air-introduced machine startup-shutdown, connecting pipe, it is ensured that system safety.
The utility model between the air-vent and air inlet of newly-increased system by setting balanced draft pipe, airduct normal condition
Lower to close, flue suction force is opened when changing greatly, the technology such as mechanical balance turnover panel opening under extreme condition, is solved to increase newly and is forced logical
The balance control problem of wind rear pass suction, it is quick timely, it is safe and reliable, safe and environment-friendly, extension converter life can be reduced.
The utility model difference with the prior art is：
The utility model always hinders damage according to newly-increased system, designs the connecting pipe between a kind of flue gas outlet and intake,
Set on pipeline and automatically adjust turnover panel, the change according to the suction at flue gas outlet automatically adjusts the aperture of turnover panel.Meanwhile, cigarette
Mechanical balance turnover panel is provided with connecting pipe between gas outlet and intake, for increasing system emergency newly in the case of
Flue suction force balance control, it is to avoid the excessive coke oven heating caused of flue suction force is abnormal.The utility model solves gravity-flow ventilation
Coke oven increases the flue suction force stability contorting problem after forced ventilation newly, and can meet coke oven steady production under various working conditions will
Ask, also adapt to coke oven heating system safety requirements under extreme condition.
The beneficial effects of the utility model：
By the utility model, coke oven can be achieved and increases newly after flue gas waste heat recovery or gas cleaning, flue suction force balance control
System, meets coke oven heating system flue suction force requirement, it is ensured that coke oven heating system safe and stable operation.
Using the utility model, coke oven blowby rate can also be reduced, pollutant emission reduction improves the tightness of body of heater, extension
The coking furnace shaft life-span.
