Description
Technical field
The utility model relates to glass kiln residual heat use device, is specifically related to a kind of glass kiln residual heat generating air and gas system.
Background technology
Glass furnace production line melting furnaces must keep zero-pressure or pressure-fired, need among scope more stable pressure control in production process.If the furnace pressure of glass furnace is negative pressure, under negative pressure state, flame space will suck extraneous freezing air, the molten kiln atmosphere of change, and the temperature of reduction melting furnaces, increases the consumption of dyestuff, and causes temperature distributing disproportionation in melting furnaces, destruction temperature of fusion system.Equally, furnace pressure can not be excessive, and furnace pressure is excessive, will make melting furnaces seriously burn with anger, and not only increases the consumption of fuel, and the scaling loss of aggravation kiln body, and be unfavorable for the clarification of glass metal and cooling.
At present, in prior art, by air and gas system and power generation assembly, when utilizing flue residue heat generating, control the pressure in kiln, reached the effect of killing two birds with one stone, can prevent from building the pressure in kiln, also can improve the utilization ratio of the energy.Existing air and gas system adopts waste heat boiler to add bypath system, in the hope of the normal operation of stable residual heat power generation system and glass furnace furnace pressure thereof.But when starting system, flue gas need to first pass through bypath system, kiln inner pressure is excessive, also need to regulate pressure by bypass, the flue gas that cigarette Wen Gaoda 550 spends is like this easy to cause the flue fan life of system to shorten, in damaged condition ahead of time, power generation system can not be moved the time very.If blower fan because fault is out of service, is easy to cause building the pressure in kiln.In addition, the flue gas that cigarette temperature is too high, is also unfavorable for subsequent disposal.
Utility model content
Technical problem to be solved in the utility model is to provide the operation of a kind of energy long-time continuous stable, makes the glass kiln residual heat generating air and gas system that glass furnace furnace pressure is stable.
The utility model adopts following technical scheme:
The utility model comprises flue collector, the residual heat flue being connected with flue collector, the waste heat boiler being connected with residual heat flue, and the exhanst gas outlet of described waste heat boiler is provided with the first induced draft fan and the second induced draft fan.
Further, the utility model also comprises controller, in the first described induced draft fan, is provided with first sensor, and the output terminal of described first sensor is connected with the input terminus of described controller, output termination first induced draft fan of described controller.
Further, in the second described induced draft fan, be provided with the second pressure transmitter, the described output terminal of the second pressure transmitter and the input terminus of controller are connected, output termination second induced draft fan of described controller.
Further, the outlet of the first described induced draft fan and the second induced draft fan is connected with thionizer.
Positively effect of the present utility model is as follows:
The utility model is simple in structure, and by two induced draft fans are set at the smoke outlet of waste heat boiler, one prevents that as standby wherein an induced draft fan breaks down, and causes building the pressure in kiln, affects the normal production of melting furnaces.Pressure in the control melting furnaces of two air inducing function assurance long-time continuous stable, makes stable normal production of melting furnaces, has guaranteed that waste heat boiler continuously provides superheated vapour to power generation system simultaneously, guarantees power generation system continuous and stable electric generation.All flue gases all pass through residual heat boiler for exchanging heat, and the flue-gas temperature that enters induced draft fan is reduced to 170 degree, greatly reduce the corrosive nature of flue gas to induced draft fan, are conducive to the follow-up desulfurization processing of flue gas simultaneously.
Whether the blast that detects induced draft fan outlet by sensor, can make Controlling System automatically identify induced draft fan and normally work, and breaks down, and controller starts standby induced draft fan automatically, realizes intelligent control, and safety is secure.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model control principle block diagram.
In the accompanying drawings: 1 flue collector, 2 residual heat flues, 3 waste heat boilers, 4 thionizers, 5 first induced draft fans, 5-1 the first pressure transmitter, 6 second induced draft fans, 6-2 the second pressure transmitter, 7 controllers.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in accompanying drawing 1,2, a kind of glass kiln residual heat generating air and gas system, comprise controller 7, flue collector 1, the residual heat flue 2 being connected with flue collector 1, the waste heat boiler 3 being connected with residual heat flue 2, waste heat boiler 3 utilizes the high-temperature flue gas in residual heat flue 2 to provide superheated vapour to power generation system, the exhanst gas outlet of described waste heat boiler 3 is provided with the first induced draft fan 5 and the second induced draft fan 6, and the first described induced draft fan 5 and the outlet of the second induced draft fan 6 are all connected with thionizer 4.In the first described induced draft fan 5, be provided with the first pressure transmitter 5-1, the output terminal of the first described pressure transmitter 5-1 is connected with the input terminus of described controller 7, in described the second induced draft fan 6, be provided with the second pressure transmitter 6-1, the output terminal of described the second pressure transmitter 6-1 is connected with the input terminus of described controller 7.The output terminal of described controller 7 is connected with the rly. of controlling the first induced draft fan 5 and the second induced draft fan 6 on/offs.
During system works, the first induced draft fan 5 is worked, and makes the state in pressure-fired in kiln, and the flue gas of residual heat flue 2 provides thermal source to waste heat boiler 3, makes power generation system stable electric generation.Because the composition in flue gas has certain corrosive nature to induced draft fan, long-play, easily break down, so when the first induced draft fan 5 quits work, the first pressure transmitter 5-1 passes to controller 7 by the signal detecting, controller 7 output signals, the second induced draft fan 6 is started, effective preventing builds the pressure in kiln like this, makes kiln inner pressure in steady state, also guaranteed power generation system stable electric generation for a long time simultaneously.
