Background technology
At present, the connected mode of existing waste heat boiler that is used for glass production line and glass production line as shown in Figure 1, the high-temperature flue gas that the kiln pond produces is undertaken by the accumulation of heat pond that heat exchange is laggard goes into flue collector, enters chimney by adjustment doors, big gate successively again, enters atmosphere by the natural draft of chimney.And the flue gas that enters atmosphere has higher heat, in order to make full use of this part heating power, reaches the purpose of energy-saving and emission-reduction, and residual heat flue is set after adjustment doors, closes big gate.High-temperature flue gas enters flue collector by the accumulation of heat pond, enters residual heat flue by adjustment doors, successively by waste heat boiler import lock gate hatch, and waste heat boiler, air-introduced machine, the heat boiler outlet lock gate hatch enters chimney at last and enters atmosphere.The heat of flue gas is by waste heat boiler the time, and the working medium of waste heat boiler is given in exchange, and the working medium after the heating is admitted to hot users such as steam turbine generator generating or heating.
Waste heat boiler is also referred to as heat recovery steam generator, and is different with conventional boiler, and combustion process does not take place in the waste heat boiler, also do not have the relevant equipment of burning, in essence, and is it that a combustion gas is looked into? the heat exchanger of steam.
Above-mentioned existing flue collector is made up of refractory brick, insulating brick, common brick etc., complex structure, and investment is high.Because higher about 600 ℃ of accumulation of heat pond outlet temperature, if refractory brick is under the high like this temperature environment for a long time, the maintenance cost height of refractory brick, so when glass production line designs, having a mind to reduce heat insulation effect partly scatters and disappears by heat, through surveying the residual heat flue point of interface, the temperature of flue collector has only 450~530 ℃, and the heat of loss is very big.
The utility model content
Technical problem to be solved in the utility model provides a kind of higher waste heat boiler heat recovery system of UTILIZATION OF VESIDUAL HEAT IN efficient that is used for glass production line.
The technical scheme that its technical problem that solves the utility model adopts is: the waste heat boiler heat recovery system that is used for glass production line, between adjustment doors on the flue collector and big gate, be connected with residual heat flue and waste heat boiler, the port of export of the working medium pipeline of waste heat boiler is connected with flue collector superheater working medium arrival end, flue collector superheater sender property outlet end connects hot user, and hot user's sender property outlet end is connected with the working medium arrival end of waste heat boiler.
Further be the bag wall formula flue collector superheater that the flue collector superheater adopts membrane type heat exchanger fin and rigid structure frame to constitute.
The beneficial effects of the utility model are: by between the arrival end of flue collector and adjustment doors the flue collector superheater being set, make full use of this part heat, working medium further is heated to the overtemperature of design from saturation temperature, guaranteeing under the constant situation of pressure and temperature, effectively improve main steam and exert oneself, thereby improve the thermal efficiency of cycle of whole power set or hot user's hot service efficiency.The flue collector superheater is arranged on the flue collector position before the adjustment doors, can replace the flue collector at this place of glass production line, in the occasion of utilizing this waste heat system generating, can make the power of cogeneration improve 10%~20%.The bag wall formula flue collector superheater that the flue collector superheater adopts membrane type heat exchanger fin and rigid structure frame to constitute, make this place not re-use refractory brick, insulating brick, common brick, reduced the cost of investment of glass production line, can be widely used in the construction of the transformation of existing glass production line waste heat boiler heat recovery system and new production line.
