To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of boiler afterheat TRT of new type of safe, including body of heater, is provided with gas approach at the top of the body of heater, described Bottom of furnace body is provided with exhanst gas outlet, and the bottom of furnace body is provided with heat pipe economizer, the moisture in the heat pipe economizer opposite heat tube Tentatively preheated, the heat pipe economizer is connected with heat pipe evaporator, the heat pipe evaporator passes through at gas approach Heat pipe evaporator makes moisture in heat pipe form saturated vapor with flue gas heat exchange, and the heat pipe evaporator passes through heat pipe evaporation and heat-exchange By the boiler smoke temperature control for passing through at 400 DEG C, below the heat pipe evaporator, superheater is connected with, the superheater will steam Vapour reheats to form superheated steam, and the heat pipe economizer, heat pipe evaporator and superheater pipeline junction are provided with drum, described Heat pipe economizer is connected with water pump water supply by pipeline, and the superheater is provided with steam (vapor) outlet, and the steam (vapor) outlet is connected with Steam turbine and electromotor, the steam turbine are connected with condenser, and the heat exchanging water pipe of the condenser is connected with cooling tower and is followed Ring is cooled down, and the condenser bottom is connected with oxygen-eliminating device by pipeline, and the oxygen-eliminating device is connected to form loop with water pump.
Preferably, the superheater is set to fin tubular type superheater, effectively strengthens heat exchange efficiency.
Preferably, the steam outlet is provided with temperature sensor, pipe temperature is detected by temperature sensor.
Preferably, water purifier is provided with the water pump, the water purifier is provided with Water quality detector, by Water quality detector Detected, when impurity is more in water quality, starts water purifier and purified, it is to avoid formed incrustation scale blocking heat pipe, reduce maintenance time Number.
Preferably, filling pipe is provided with the water pump, the supplement for carrying out moisture by filling pipe, it is to avoid water deficient is made Reduce into heat exchange efficiency.
The beneficial effects of the utility model show:The efficient utilization of residual heat from boiler fume generating is achieved, by heat pipe Vaporizer controls flue-gas temperature at 400 DEG C, and due to the good isothermal performance of adopting heat pipes for heat transfer, heat pipe wall surface temperature is than medium temperature in pipe High 60 DEG C or so are spent, High Temperature Corrosion can be prevented effectively from, so that superheater will not be subject to high temperature corrosion, it is overheated to protect Device, while 400 DEG C or so flue gas even dry combustion methods are also not result in boiler tube bursting, therefore superheater has good safety, keeps away Exempted from the generation of accident, the utilization for superheated steam being realized by superheater, the steam consumption substantially reduce, with good economy, adopted With temperature sensor monitor in real time temperature, labor strength is reduced, improve stability and safety.
