Description
Technical field
The present invention relates to energy-conserving and environment-protective technology, more particularly to exhaust gas purifying treatment system.
Background technology
Large quantity of exhaust gas can be produced in industrial processes, contains oxious component in waste gas in many cases, if untreated
It is directly discharged into air to pollute the environment, destruction is ecological, unhealthful；Additionally, often containing some active ingredients in waste gas again, give up
Temperature degree is also higher, with certain heat energy, if being not added with recycling directly discharge, causes the energy, the wasting of resources and air dirty
Dye；But often while also containing the impurity such as solid particulate matter, fiber, mist of oil, this purified treatment and resource to waste gas in waste gas
Recycling brings difficulty.The presence of the complicated and impurity of waste gas components, it is easy to make useless using reason outside catalytic combustion technology
The catalyst poisoning of gas, failure；Using flame combustion process, there is the risk for producing extremely toxic substance dioxin；Therefore, Bu Shaoyan
Study carefully personnel and waste gas is processed using cooling means, to recycle active ingredient.But, cooling waste gas needs to consume big energy,
Again disposal of pollutants is increased in turn.
The content of the invention
The technical problem to be solved is just to provide a kind of exhaust gas purifying treatment system, obtains waste gas effectively net
Change is processed, while resource is fully recycled,.
To solve above-mentioned technical problem, the present invention is adopted the following technical scheme that：A kind of exhaust gas purifying treatment system, including
Filter, several exhaust gas heat exchangers, separate type heat pipe exchanger, cooler, adsorber, it is useless that the filter is used for filtration removal
Granule in gas, waste gas sequentially passes through several exhaust gas heat exchangers after filter filtration and carries out heat exchange cooling recovery heat energy
Afterwards, then after separated formula heat exchange of heat pipe evaporator section pre-cooling cooler is entered, the cooler carries out further cold to waste gas
But adsorber, the partial elements that the adsorber is used in the waste gas that adsorbing separation cooler is discharged, from adsorber row are entered afterwards
The waste gas stream for going out crosses the condensation segment of separate type heat pipe exchanger and reclaims cooler cold, and waste gas is discharged in air after reheating.
Preferably, several exhaust gas heat exchangers include the first exhaust gas heat exchanger, the second exhaust gas heat exchanger and separate type
Heat exchange of heat pipe；The separate type heat pipe exchanger evaporator section is after the second exhaust gas heat exchanger, cooler, and the separate type is hot
Heat exchange of heat pipe condensation segment, for pre-cooling waste gas, reclaims cold after cooler, adsorber.
Preferably, described several exhaust gas heat exchangers include the first exhaust gas heat exchanger, the second exhaust gas heat exchanger, described the
One exhaust gas heat exchanger and the second exhaust gas heat exchanger are connected with Absorption Refrigerator, and the Absorption Refrigerator is driven by heat energy from waste gas
Dynamic and output cold is to cool down waste gas.
Preferably, cryogenic media of the cooling medium of the cooler for Absorption Refrigerator, flows through the useless of cooler
Gas is cooled down by the cryogenic media from Absorption Refrigerator.
The technical solution used in the present invention, after waste gas is filtered, flows through the first exhaust gas heat exchanger, using waste gas temperature
The higher partial heat energy of degree drives Absorption Refrigerator, and the cold of output is to cool down waste gas；Afterwards waste gas flows through the second waste gas
Heat exchanger, recovery section heat energy, is further cooled；Afterwards waste gas again pass through separate type heat pipe exchanger evaporator section carry out it is pre-
Cold, afterwards waste gas enters cooler, is cooled down by depth, and afterwards waste gas enters adsorber, and partial elements therein is adsorbed to be separated,
Waste gas is finally entered before air, flows through separate heat pipe condensation segment, is heated by the steam from separate heat pipe evaporator section, is returned
Receiving portions cold, waste gas is by pre-cooling.Therefore, the present invention takes full advantage of waste gas self-energy, waste gas is obtained at effective purification
Reason, is a kind of energy-efficient environmental protecting device while fully recycling resource.
Description of the drawings
With reference to the accompanying drawings and detailed description the invention will be further described：
Fig. 1 is embodiment of the present invention schematic diagram.
Specific embodiment
As shown in figure 1, a kind of exhaust gas purifying treatment system, including the heat exchange of filter, the first exhaust gas heat exchanger, the second waste gas
Device, Absorption Refrigerator, separate type heat pipe exchanger, cooler, adsorber.
Waste gas is introduced into filter, and the first exhaust gas heat exchanger is flow through after preliminary purification, heats therein from absorption system
The heat-carrying agent of cold generator, waste gas is cooled, and temperature is reduced；Afterwards, waste gas flows through the second exhaust gas heat exchanger, and heating is wherein
Medium, waste gas is further cooled, and high boiling point composition is condensed and separates；Waste gas then flows through separate type heat pipe exchanger
Evaporator section, heats working medium therein, makes the condensation segment that separate type heat pipe exchanger is flowed into after working medium vaporization, and waste gas is by further pre-
Cooling, the composition of which part higher is condensed, separates；Then, waste gas stream subcooler, by from absorption system
The cryogenic media cooling of cold, low boiling composition in part therein is also cooled and separates；Afterwards waste gas flows through adsorber, its
Middle remaining composition is adsorbed, separation；Finally, the waste gas stream through a series of aforementioned process crosses the condenser of separate heat pipe,
Gas is amplified by steam reheating heel row therein, and steam condensation becomes after liquid, and evaporator section is flowed back under gravity, inhales again
Heat, evaporation.
Above-mentioned technical proposal, drives the cold of Absorption Refrigerator, output to use using the higher partial heat energy of EGT
To cool down waste gas；Using separate type heat pipe exchanger pre-cooling waste gas, cold energy is reclaimed, save cooling energy consumption, take full advantage of waste gas
Self-energy, makes waste gas obtain effective purified treatment.
