Description
Technical field
The utility model relates to glass melter cogeneration station system, particularly the furnace pressure control device of glass melter cogeneration station system.
Background technology
The construction in waste heat power station at first will guarantee the security and the stability of glass melter, secondly just considers to improve utilization rate of waste heat and generating efficiency.The main production feature of glass melter is requirement kiln temperature field, pressure field and fluctuation of metal line is little, safety and stability, for guaranteeing the quality of glass metal, controls such as the pressure in the glass melter require extremely strict, and the pressure control in the glass melter is an important thermal parameter of glass melter.
After building the waste heat power station for improving utilization rate of waste heat or being the desulfurization and dedusting needs, all flue gases in the glass melter all will be by producing the waste heat boiler of superheated steam, this just requires the waste heat boiler air and gas system in power station must be safe and reliable, otherwise will influence glass production, therefore, build the waste heat power station require the waste heat boiler air and gas system under any circumstance guarantee to discharge fume unobstructed, furnace pressure control is stable.Pressure control in traditional glass melter at first is to guarantee that the pressure behind the rotation flashboard is in certain scope on the main chimney flue, by regulating the aperture control kiln inner pressure of rotation flashboard on the main chimney flue, and the pressure behind the rotation flashboard mainly is to guarantee by the saturated vapor waste heat boiler by smoke directly ventilating chimney or the in line chimney of partial fume, partial fume.Therefore its pressure degree of accuracy is difficult to guarantee.
The utility model content
The purpose of this utility model is exactly for the shortcoming that the pressure degree of accuracy that exists in the prior art is difficult to guarantee, the furnace pressure control device of a kind of glass melter afterheat generating system that provides are provided.
To achieve these goals, the present invention has adopted following technical scheme:
The furnace pressure control device of glass melter afterheat generating system, comprise by main chimney flue rotation flashboard, the boiler inlet flashboard, waste heat boiler, air-introduced machine, air-introduced machine outlet flashboard, emergent flashboard, desulfation dust-extraction device, main chimney flue and main chimney flue block the afterheat generating system that flashboard is formed, it is characterized in that: described furnace pressure control device is by pressure transmitter, DCS and frequency converter are formed, pressure transmitter is arranged in the pipeline behind the main chimney flue rotation flashboard of glass melter, the pressure transmitter signal output part links to each other with DCS, the drive motors of each flashboard in the Intelligent Fuzzy Control algoritic module in the DCS and the afterheat generating system links to each other, and frequency converter one end links to each other with air-introduced machine, the other end links to each other with the Intelligent Fuzzy Control algoritic module of DCS inside.
DCS in the technique scheme belongs to ripe prior art, i.e. Distributed control system, i.e. scattered control system.
Advantage of the present utility model: can implement accurately control to the melting furnaces internal pressure, and property easy to use, safe is good, has especially solved the technical barrier of glass melter middle and low temperature waste heat power generation, has improved the economic benefit of glass melter.
Description of drawings:
Fig. 1 is a glass melter afterheat generating system schematic diagram;
Fig. 2 is the block diagram of furnace pressure control device.
The specific embodiment:
As shown in Figure 1, the furnace pressure control device of the glass melter afterheat generating system that the utility model provides comprises by main chimney flue rotation flashboard 2, boiler inlet flashboard 6, waste heat boiler 7, air-introduced machine 9, air-introduced machine outlet flashboard 10, emergent flashboard 8, desulfation dust-extraction device 11, main chimney flue 5 and main chimney flue and blocks the afterheat generating system that flashboard 4 is formed.
As shown in Figure 2, furnace pressure control device of the present utility model, form by pressure transmitter 3, DCS and frequency converter, pressure transmitter 3 is arranged in the pipeline behind the main chimney flue rotation flashboard 2 of glass melter (as shown in Figure 2, the pressure transmitter signal output part links to each other with DCS, the drive motors of each flashboard in the Intelligent Fuzzy Control algoritic module in the DCS and the afterheat generating system links to each other with the rotation of controlling each motor or stops, and frequency converter one end links to each other with the motor of air-introduced machine 9, the other end links to each other with the Intelligent Fuzzy Control algoritic module of DCS inside.
The utility model for guarantee the waste heat power station in all cases the pressure behind the glass melter main chimney flue rotation flashboard in setting range.When waste heat boiler normally moves, DCS according to setting value automatic setting boiler after the frequency of air-introduced machine frequency converter, when the frequency feedback signal of the pressure signal of pressure transmitter measurement or frequency converter surpasses alarming value, all send alarm signal.The inner Intelligent Fuzzy Control algorithm that adopts of DCS, faults such as air-introduced machine behind boiler or frequency converter, when the pressure behind the rotation flashboard 3 surpasses safety value, the emergent bypass flashboard 8 of DCS control is opened, the melting furnaces main chimney flue blocks flashboard 4 and opens the signal of closing with waste heat boiler import flashboard 6, make pressure behind the glass melter main chimney flue rotation flashboard 3 in normal range (NR), thereby guarantee that the glass melter smoke evacuation is unobstructed, furnace pressure is stable in the glass melter.
