Description
Technical field
The present invention relates to technical field of air purification, more particularly to a kind of air purification method of temperature reaction processing.
Background technology
In order to save the energy, the increase of modern architecture closure degree, due to its central air conditioner system scavenging utilities imperfection,
Cause indoor pollutant to discharge outdoor in time, cause IAQ to deteriorate.At present, the indoor air cleaning typically used
Change technology is usually：（1）Filtration method, this method can only filter out bulky grain thing in air, and can not remove waving in air
The harmful substances such as hair property organic matter, nitrogen oxides, oxysulfide, carbon monoxide；（2）Absorption method, this method is mainly using porous
Property sorbing material such as porous silica, activated carbon, activated alumina, ceramics or zeolite remove the noxious substance in air
Go, but this method needs different sorbing materials generally directed to different harmful substances, therefore to realize room truly
Interior air comprehensive decontamination difficulty is larger, although acticarbon can adsorb most harmful substance, due to its adsorbance
Limited, adsorbent needs frequent regeneration, particularly activated carbon to have the possibility of spontaneous combustion in more than 573K, is caused to regeneration sizable
Difficulty, limit its application.（3）Photocatalytic oxidation, this method are the photocatalytic activities using catalyst, are urging absorption
Redox reaction occurs for the VOCs for changing dielectric surface, is eventually converted into carbon dioxide, water and inorganic molecules material, due to
Cheap two wide material sources of TiO2, high to uv absorption rate, anti-light corrosivity, chemical stability and catalytic activity are high, and
There is no toxicity, have stronger suction-operated to many organic matters, thus turn into the most frequently used photochemical catalyst, the master of photocatalytic oxidation
Wanting advantage is：Capacity usage ratio is high, is generally operated at normal temperatures, no coupling product is formed, and the catalyst after use can be used
Physics and chemical method regeneration Posterior circle use, but this method can only degrade volatile organic matter, can not go denitrification and
The harmful substances such as oxysulfide.
Air treating in the market substantially can not fully and effectively purify the pollution in air with purification techniques
Thing, reach the requirement of Indoor Air Quality standards comprehensively, it would be highly desirable to which exploitation can effectively administer the method to purify the air of a room comprehensively.
The content of the invention
Present invention aim to address above-mentioned deficiency, there is provided a kind of air purification method of temperature reaction processing.
The present invention technical solution be：A kind of air purification method of temperature reaction processing, as follows：It will treat
Purification air is filtered using filter, removes the coarseparticulate in air, and the air after filtering is sent into compressor
Row adiabatic compression, the air to be clean make atmosphere temperature rising to subsequent catalyst reacting middle catalyst after compressor adiabatic compression
Active temperature, wherein compression heating after air themperature be 50-400 DEG C, volume compression ratio 3-6；Air after compression enters
Enter catalytic cleaner, the harmful substance in air changes into harmless gas in the presence of catalyst；It will pass through at catalytic cleaner
Purification air after reason carries out heat exchange cooling by cooling heat exchanger；The purification air after heat exchange is sent into expanding machine afterwards to carry out
Adiabatic expansion, air cooling-down is depressured, suitable for conveying, and the expanding machine adiabatic expansion is done work and is conveyed to the step
A) compressor in；Purification air Jing Guo adiabatic expansion is sent into damping equipment, the humidity of regulation purification air.
In the step c), the purification air after catalytic cleaner is handled is passed through in cooling heat exchanger and step a)
Air heat-exchange to be clean cooling.
The present invention has the following advantages：Atmosphere temperature rising is made to the active temperature of catalyst, the party using compressor adiabatic compression
Method is simple and easy, easy to operate, can effectively remove the pollutant in air；, will using expanding machine to the air cooling-down after purification
The expansion work of expanding machine is conveyed to compressor, for compressor operating, can significantly reduce energy consumption.
Embodiment
A kind of air purification method of temperature reaction processing of the present invention, as follows：Air to be clean is adopted
Filtered with filter, remove the coarseparticulate in air, the air after filtering is sent into compressor and carries out adiabatic compression,
