Description
Technical field
This utility model relates to a kind of air cleaner, more specifically, is a kind of low concentration using catalyst runner
VOC contaminated air purifier.
Background technology
Along with semiconductor crystal wafer processing and the highly integrated and high performance of integrated circuit, in order to improve semiconductor crystal wafer
Processing, surface-mounted integrated circuit manufacture, the quality of the various electronic components such as LCDs production and the yield rate of product.For producing
The requirement of the clean room required for environment is more and more higher.Manage according to strict cleannes of carrying out of regulation such as manufacturing engineering cleaning rooms
Just become most important.And how to reduce the chemical compositions such as dust, VOC in cleannes benchmark and also become critically important asking
Topic.
(building standard method, implement order with method and execute with method additionally, the new method of room air pollution that Japan's Heisei 15 years is implemented
A part for line discipline corrects to be implemented) define the measure dissipating in health for chemical substance in room, denote indoor
The concentration pointer value of formaldehyde and VOC etc..During for exceeding this pointer value situation, it will usually use forced ventilation mode by building materials
And the dusty gas forced ventilation such as the VOC that is dispersed in nature such as glue or force to produce building materials etc. by raising indoor temperature
VOC discharge chamber outside method.These methods, while overwhelming majority VOC can be distributed in 4 after completion～6 months so that it is
Below pointer value, but period length and produced by ventilation air conditioner energy loss just become problem.
In order to purify these VOC, (Japan is special for patent document 1 (Japanese Unexamined Patent Publication 7-256048 publication) and patent document 2
Open flat 10-15339 publication) in disclose use containing catalyst portion and the double-deck runner of sorbent material part and containing touching
The purifier of the runner of the mixture of matchmaker and sorbent material.Additionally patent document 3 (Japanese Unexamined Patent Publication 2002-204919 public affairs
Report) in disclose and use catalyst adsorption runner to decompose the suction off loading of regeneration air after VOC concentrates to put.Further, patent document 4
(Japanese Unexamined Patent Publication 10-244125 publication) discloses platinum catalyst is set at rotary wheel regeneration outlet side or process outlet side
Layer, arranges two-layer renewing zone, and any one can be with the concentration device processing air counter current flow.
Although disclose in patent document 1 that the part being made up of catalyst and sorbent material overlaps with gas circulating direction turns
Take turns and be divided into by the runner containing catalyst and sorbent material mixture the purifier for the treatment of region, renewing zone and clear area.But
It is to there is the problem owing to catalyst amount is not enough and the catalyst of decomposition temperature deficiency generation cannot decompose completely.It addition, process outlet
The air part at place imports clear area, the problem that clear area cooling effect is the best as clean air.
Patent document 2 proposes above-mentioned runner is divided into treatment region, regenerate 1st district, regenerate 2nd district and 4, clear area district
The purifier in territory, but owing to regenerative heater is arranged on process outlet side, VOC concentration is higher, therefore there is reactivation outlet
The problem that (i.e. processing entrance) side catalyst decomposition efficiency does not give full play to.
Although patent document 3 proposes the adsorption desorption device employing common sorption runner, set at exhaust flow path
Put catalyst decomposition heater 4 and harmful gas ingredient breakdown removing catalyst 8, but sorption enrichment facility and catalyst have decomposed dress
It is necessary for putting, and device complicates, and has resulted in the problem that original cost increases.
The sorption runner made by the hydrophobic zeolite as sorbent is used, segmentation although patent document 4 proposes
Have a concentration device for the treatment of region, preheating zone, renewing zone and clear area, but due to renewing zone and preheating zone air flow with
The air flow for the treatment of region defines counter current flow, (preheating gas aerofluxus that the flow process that the most not only system is all has just become complicated
Become the opposite of runner, will pipe arrangement by preheating gas supply side, it is necessary to return), processed gas supply side i.e. preheats
The runner internal temperature step-down of gas exhaust side and deodorize gas exhaust side, causes the problem that catalyst can not decompose completely.
