It is used, does not only result in heat energy and do not used fully, and produce thermal pollution, the industry for transitional period energy-saving and emission-reduction passes through
It is not the act taken advantage of a situation really for Ji.And current heat utilization apparatus and method are a lot, but it is gentle for this band heat of flue gas
The complex mixture of a variety of phases such as body, solid, liquid is handled often not enough in place, therefore is utilized general insufficient.In order to increase
The heat of flue gas and the recovery utilization rate of discarded object, it is necessary to which modernization overlay is carried out to recovery process.
The content of the invention
Goal of the invention：In order to improve the heat and material recycle rate of the mixture of this more facies tract heat of flue gas, the present invention
A kind of high performance flue gas and water mixing heat recovering process are designed, to solve problems of the prior art.
The content of the invention：A kind of flue gas and water mixing heat recovering process, comprise the following steps：
（1）, prepare what a circulation air and liquid mixer, an atomizer, flue gas by air-introduced machine enter flue after introduce
Air and liquid mixer is circulated, concentration detector is provided with flue, return valve and concentration detector are electrically connected with the controller, and are returned
Flow the aperture of valve and the sensing mechanisms of concentration detector is controlled by controller, atomizer adds water and absorbent；
（2）, flue gas enter air and liquid mixer, by clear water add absorbent dissolving after, into atomizer, water smoke and cigarette after atomization
Gas is sufficiently mixed, and according to technological requirement, the regulating valve of atomizer connection is electrically connected with the controller and is controlled by it aperture, according to cigarette
The concentration detector of gas feeds back to the data of controller, and controller adjusts the aperture of regulating valve；
（3）, step（2）In gas-liquid mixture by filter screen, gas-liquid mixture enters recovery hot channel, filtering after filtering
Stay in after the residue of filter screen gathers as bed material and further handle afterwards.
Preferably, step（3）In, the aperture of filter screen is at 2.5-50 μm.The aperture of filter screen is directed to various mistakes
Filter the whole cooperation of climatic conditioning.
Preferably, step（1）In, the sensing mechanisms perceives the solid content in flue gas.Solid content is perceived with to atomization
Device regulation flow provides reference, because solid particle is the most intractable part in flue gas.
Preferably, the circulation air and liquid mixer outer layer has heat insulation layer.Heat insulation layer gives circulation gas-liquid mixture insulation.
Preferably, the heat insulation layer is one in styrofoam, pearl cotton, mineral wool, ethylene propylene diene rubber, nitrile rubber
Kind.Above different materials heat insulating ability performance is fabulous.
Preferably, the absorbent includes sodium acid carbonate, isopropanol.Sodium acid carbonate absorbs sour gas common in flue gas
Body, isopropanol mix the compatibility performance for improving absorbing liquid synthesis with water, dissolve segment polarity and nonpolar medium.
Preferably, step（2）In, the ratio between flow of the water smoke and flue gas meets, the heat of flue gas evaporates water smoke
Ratio 16 ~ 37%.The ratio between this water smoke flue gas flow can obtain good thermal condition.
Compared to the prior art, the beneficial effects of the present invention are：A kind of flue gas and water mixing recuperation of heat work of the present invention
Skill, ingenious in design, heat utilization efficiency is high.The setting of circulation air and liquid mixer makes the liquid of atomization and flue gas more be sufficiently mixed, and making can
Molten and dispersible material is dispersed in drop as far as possible, while heat is exchanged；Flue gas enters air and liquid mixer, water smoke and flue gas
Mixing, and flue gas solid perceives and nebulizer flow regulation, and by way of controller control, overall controllable, and has
There is very strong inversion of phases function；Obtained mixed phase, which enters recovery hot channel, can realize heating to material, and the solid left is residual
Stay further processing.Present invention process is flexible, and regulation mechanism is simple and quick, is quick on the draw, and realizes for flue gas solid content
And the ratio that Automated condtrol liquid mist is mixed with has larger push away so as to regulate and control the obtained heat exchange degree of mixture
Wide application value.
Brief description of the drawings
Fig. 1 is the technological process schematic block diagram of the embodiment of the present invention.
