The specific embodiment
Through specific embodiment heat energy from waste gas environmental protection comprehensive utilization device of the present invention is done further to describe in detail below.
As shown in Figure 1; Heat energy from waste gas environmental protection comprehensive utilization device; Comprise first heat exchanger 1, heating clamber 2, catalyst chamber 3, second heat exchanger 4 and blower fan 5; Be provided with catalyst in the catalyst chamber 3; The two ends of first heat exchanging pipe of said first heat exchanger 1 connect the waste gas gas outlet and the air inlet of heating clamber 2 of baking oven 6 respectively through pipeline, the gas outlet of heating clamber 2 connects the air inlet of catalyst chamber 3 through pipeline, and the two ends of second heat exchanging pipe of first heat exchanger 1 are an end of first heat exchanging pipe of the gas outlet through pipeline connection catalyst chamber 3 and second heat exchanger 4 respectively; The other end of first heat exchanging pipe of second heat exchanger 4 is connected through the air inlet of pipeline with blower fan 5, and the two ends of second heat exchanging pipe of second heat exchanger 4 connect the air inlet of air source 7 and baking oven 6 respectively.
As preferred version, be provided with arm 8 in the pipeline between said first heat exchanger 1 and second heat exchanger 4, arm 8 is provided with proportioning valve 9, and the other end of arm 8 connects the air inlet of baking oven 6.
As preferred version, be provided with water heater 10 in the pipeline between said second heat exchanger 4 and the blower fan 5.Can come the water in the heating water heater 10 through the hot gas in first heat exchanging pipe of second heat exchanger 4, thereby make heat energy further obtain utilizing.
Operation principle of the present invention is: from the organic exhaust gas that comes out in the waste gas gas outlet of baking oven 6, typical temperature is about 100 ℃, and organic exhaust gas is after getting into heating clamber 2 behind first heat exchanging pipe of first heat exchanger 1; Through being heated to about 260 ℃, get into catalyst chamber 3 then, be purified after organic matter in the organic exhaust gas and the catalyst reaction; And discharge great amount of heat, make the temperature of gas rise between 450 ℃～650 ℃, second heat exchanging pipe of the gas of high temperature back entering by the road first heat exchanger 1; Carry out heat exchange with the organic exhaust gas in first heat exchanging pipe of first heat exchanger 1, make the temperature of organic exhaust gas be improved, be generally about 150 ℃; Thereby can reduce the energy consumption of heating clamber 2, and the gas temperature in second heat exchanging pipe is reduced between 350 ℃～450 ℃, gas then gets in second heat exchanger 4; And carry out heat exchange with the normal temperature air in the external source of air 7; Thereby make gas temperature further be reduced to≤200 ℃, and normal temperature air is heated to≤250 ℃, gas heats the water in the water heater 10 when water heater 10; Make heat energy further obtain utilizing emptying behind blower fan 5 then; Normal temperature air is delivered in the baking oven 6 after heating, makes the temperature in the baking oven 6 satisfy user demand.In addition, when the temperature in the baking oven 6 can not reach user demand, can open the proportioning valve 9 in the arm 8, the high-temperature gas in the pipeline between first heat exchanger 1 and second heat exchanger 4 is directly got in the baking oven 6, mix the degree supply for baking oven 6.
If the present invention is not provided with second heat exchanger 4; And the gas after heat exchange in first heat exchanger 1 is directly fed baking oven 6; After the catalyst in the catalyst chamber 3 lost efficacy, then equal organic exhaust gas is sent in the baking oven 6 again, cause easily in the baking oven 6 that exhaust gas concentration raises and causes blast.It is through being provided with second heat exchanger 4, sends in the baking oven 6 after making extraneous air obtain heating and uses, thereby prevent to cause in the baking oven 6 after catalyst in the catalyst chamber 3 lost efficacy potential safety hazard takes place.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
