Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated:
Embodiment: see accompanying drawing 1, tail gas preheating heating system, be provided with automobile exhaust pipe, a noise silencer 1 described automobile exhaust pipe is equipped with, described automobile exhaust pipe is connected with the water back 4 in foul water tank 3 by an operated pneumatic valve 2, gas in storage tank 5 is by gas circuit and two-position three way magnetic valve 6 and operated pneumatic valve 2 control linkage, and described two-position three way magnetic valve 6 supplies to be electrically connected by fuse 11 and storage battery 12 by coolant-temperature switch 1 in parallel, coolant-temperature switch 28, hand switch 1, hand switch 2 10; Described two-position three way magnetic valve adopts electromagnetic gas valve; Described coolant-temperature switch one temperature is set as 20 DEG C, coolant-temperature switch two temperature is set as 40 DEG C, is respectively provided with a temperature switch to control the power on/off of electromagnetic gas valve inside and outside foul water tank.
Conducting state is in lower than coolant-temperature switch 1 when 20 DEG C in external temperature, same coolant-temperature switch 2 be also in conducting state at this moment circuit turn-on electromagnetic gas valve obtain electric, make spool be in conducting state after solenoid valves, the pressurized air in storage tank is through tracheae, electromagnetic valve, operated pneumatic valve.Operated pneumatic valve is closed under the promotion of cylinder.Directly can not enter air by exhausr port again through the tail gas of noise silencer after operated pneumatic valve closes, but turn at valve place and enter heating pipe.Heating pipe displacement foul water tank is inner, enters in the process of heating pipe discharge at tail gas, and the heat in tail gas is conducted by heating pipe and makes sewage intensification keep liquid to the sewage in foul water tank.Trigger coolant-temperature switch 2 when anh temperature rises to 40 DEG C, coolant-temperature switch 2 has conducting to become the reset of disconnection electromagnetic valve dead electricity operated pneumatic valve, and tail gas stops the heating to cistern free from the exhausr port discharging directly into atmosphere that resistance is little again.When the water temperature of sewage is down to reset temperature (30 DEG C) of coolant-temperature switch 2, coolant-temperature switch 2 replys conducting, and battery valve obtains and electricly makes operated pneumatic valve again close tail gas to reenter heating pipe and heat foul water tank.The route of discharging along with the change tail gas of foul water tank water temperature like this to change to keep sewage temperature to control within a stable scope entering between heating pipe or discharging directly into atmosphere.
