Abstract
The utility model discloses a control system on a glass production line, particularly to a kiln pressure stabilizing system for a glass production line waste heat power generation kiln, which controls parameters during the technical process and can well stabilize kiln pressure. The system comprises a waste heat flue arranged between a regulating restrictor gate and a large restrictor gate on a main flue, and a waste heat boiler and an induced draft fan arranged on the waste heat flue, wherein a pressure sensor is arranged on the main flue at the rear part of the regulating restrictor gate. A control system controls the rotation speed of the regulating restrictor gate and the induced draft fan at the same time according to feedback signals from the pressure sensor. When the kiln pressure is fluctuated, the control system regulates the action of the regulating restrictor gate and controls a frequency converter as an auxiliary control means to regulate the rotation speed of the induced draft fan, thereby more accurately stabilizing the pressure of the glass kiln. The technical scheme provided by the utility model can be widely applied to the transformation of a heat recovery system for a prior glass production line waste heat boiler and the construction of a new production line equipped with a waste heat power generation system.
Description
Technical field
The utility model relates to the Controlling System on a kind of glass production line, especially the glass production line cogeneration furnace pressure stable system that the parameter in the technological process is controlled.
Background technology
Glass production line melting furnaces ordinary production kiln temperature deviation control is in standard temperature ± 1 ℃, maximum at ± 2～3 ℃, furnace pressure is normally controlled pressure-fired 4.7Pa, deviation control is at ± 0.3Pa, even in changing fiery process, furnace pressure, kiln temperature also are to be controlled in the more stable scope, and the klin pressure fluctuation when changing fire is at+7-10Pa.Malleation does not have much affect to kiln, and negative pressure is just bad, and freezing air enters.Changes in weather, wind-force size, seasonal variation, atmospheric moisture all can influence furnace pressure.
At present, in the existing glass production line, the high-temperature flue gas that the glass kiln produces is undertaken by the accumulation of heat pond that heat exchange is laggard goes into flue collector, more successively by regulate lock gate hatch, the big damper door enters chimney, enters atmosphere by the natural draft of chimney.Have higher heat and enter atmospheric flue gas,, reach the purpose of energy-saving and emission-reduction, residual heat flue is set behind the door, close big gate at the adjusting flashboard in order to make full use of this part heating power.High-temperature flue gas enters flue collector by regenerator, enters residual heat flue by regulating lock gate hatch, and by waste heat boiler imported valve, waste heat boiler, induced draft fan, the heat boiler outlet valve enters chimney at last and enters atmosphere successively.After increasing waste heat boiler, flue resistance increases about 700pa, increases induced draft fan in the exhaust-heat boiler flue gas outlet, to stablize furnace pressure, guarantees flue gas flow rate.
On existing glass production line, Controlling System generally adopts DCS (DCS: dcs, automatic control industry at home is referred to as distributed control system again) control, furnace pressure is regulated in real time by regulating flashboard, regulates control by pressure transmitter closed loop PID (proportion integration differentiation); Glass production line is mainly regulated the control furnace pressure by regulating lock gate hatch, thereby guarantees the ordinary production of glass thread.Only, have the problem of following several respects by regulating flashboard gate control furnace pressure, 1, when changing fire pressure surge bigger, can't stablize furnace pressure; 2, klin pressure fluctuation is big when climate change, poor stability; 3, enter the later stage at kiln, the regenerator resistance increases, and regulating lock gate hatch can not the complete stability furnace pressure.
From above-mentioned several situations as can be known to the influence of furnace pressure, no matter be new kiln or old kiln, factors such as the variation of regenerator resistance, Changes in weather all can influence the stable of furnace pressure, all only adopted the regulating and controlling lock gate hatch to come the stable of furnace pressure controlled in the former design, thereby the effect of stablizing furnace pressure is relatively poor, and stability is bad.
The utility model content
Technical problem to be solved in the utility model provides a kind of glass production line cogeneration furnace pressure stable system of better effects if of stable furnace pressure.
The technical scheme that its technical problem that solves the utility model adopts is: glass production line cogeneration furnace pressure stable system, comprise adjusting lock gate hatch and the residual heat flue between the big damper door that is arranged on the flue collector and be arranged on waste heat boiler and induced draft fan on the residual heat flue, the flue collector of regulating the rear portion of lock gate hatch is provided with pressure transmitter, Controlling System is regulated control according to the signal of pressure transmitter feedback to regulating lock gate hatch, and it is characterized in that: Controlling System is regulated control to the rotating speed of induced draft fan simultaneously according to the signal of pressure transmitter feedback.
As optimized technical scheme, Controlling System is carried out variable frequency adjustment control by frequency transformer to the rotating speed of induced draft fan.
The beneficial effects of the utility model are: because the technical scheme that has adopted Controlling System simultaneously the rotating speed of regulating lock gate hatch and induced draft fan to be controlled according to the signal of pressure transmitter feedback, when klin pressure fluctuation, Controlling System is regulated the lock gate hatch action, Controlling System control of conversion device is as the subcontrol means, regulate the rotating speed of induced draft fan, the pressure of accurate more stabilized glass kiln.The technical solution of the utility model can be widely used in the construction of production line of the transformation of existing glass production line waste heat boiler heat recovery system and new outfit afterheat generating system.
