Specific embodiment
Heat energy from waste gas Environmental-protection comprehensive of the present invention is described in further detail using device below by specific embodiment.
As shown in Figure 1, heat energy from waste gas Environmental-protection comprehensive utilize device, including First Heat Exchanger 1, heating room 2, catalyst chamber 3,
Second heat exchanger 4 and blower 5 are provided with catalyst, the both ends point of the first heat exchanging pipe of the First Heat Exchanger 1 in catalyst chamber 3
Not by the air inlet of the exhaust gas outlet of piping connection baking oven 6 and heating room 2, the gas outlet of heating room 2 passes through piping connection
The both ends of the air inlet of catalyst chamber 3, the second heat exchanging pipe of First Heat Exchanger 1 pass through the outlet of piping connection catalyst chamber 3 respectively
One end of first heat exchanging pipe of mouth and the second heat exchanger 4, the other end of the first heat exchanging pipe of the second heat exchanger 4 pass through pipeline
It is connected with the air inlet of blower 5, the both ends of the second heat exchanging pipe of the second heat exchanger 4 are separately connected air-source 7 and baking oven 6
Air inlet.
Preferably, branch pipe 8, branch pipe are provided in the pipeline between the First Heat Exchanger 1 and the second heat exchanger 4
Proportioning valve 9, the air inlet of the other end connection baking oven 6 of branch pipe 8 are provided on 8.
Preferably, water heater 10 is provided in the pipeline between second heat exchanger 4 and blower 5.It can lead to
The hot gas crossed in the first heat exchanging pipe of the second heat exchanger 4 carrys out the water in heat hot water device 10, so that thermal energy be made further to obtain
It utilizes.
The working principle of the invention is：The organic exhaust gas come out from the exhaust gas outlet of baking oven 6, typical temperature are 100 DEG C
Left and right is heated to 260 DEG C or so, so after organic exhaust gas enters heating room 2 after the first heat exchanging pipe of First Heat Exchanger 1
Enter catalyst chamber 3 afterwards, the organic matter in organic exhaust gas is purified after reacting with catalyst, and releases a large amount of heat, is made
The temperature for obtaining gas rises between 450 DEG C~650 DEG C, and the gas of high temperature enters the second of First Heat Exchanger 1 afterwards by the road and changes
Organic exhaust gas in pipe line, with the first heat exchanging pipe of First Heat Exchanger 1 carries out heat exchange, so that the temperature of organic exhaust gas obtains
To raising, usually 150 DEG C or so, so as to reduce the energy consumption of heating room 2, and make the gas in the second heat exchanging pipe
Temperature is down between 350 DEG C~450 DEG C, and gas subsequently enters in the second heat exchanger 4, and with the room temperature in external source of air 7
Air carries out heat exchange, so that gas temperature be made to be further reduced to≤200 DEG C, and normal temperature air is heated to≤250 DEG C,
Gas is utilized thermal energy further, then empties after blower 5 through heating the water in water heater 10 when water heater 10；
It is sent after normal temperature air is heated into baking oven 6, satisfies the use demand the temperature in baking oven 6.In addition, when the temperature in baking oven 6
When cannot reach use demand, the proportioning valve 9 in branch pipe 8 can be opened, make to be located at First Heat Exchanger 1 and the second heat exchanger 4 it
Between pipeline in high-temperature gas be directly entered in baking oven 6, give baking oven 6 mixed degree supply.
If the present invention is not provided with the second heat exchanger 4, and the gas in First Heat Exchanger 1 after exchanging heat is passed directly into baking
Case 6 is then equal to and organic exhaust gas is re-fed into baking oven 6 after the catalyst in catalyst chamber 3 fails, and easily causes in baking oven 6 and gives up
Gas concentration increases and causes to explode.It is by the second heat exchanger 4 of setting, so that outside air is sent into baking oven 6 after being heated
It uses, to after preventing the catalyst in catalyst chamber 3 from failing cause that security risk occurs in baking oven 6.
