Abstract

The invention relates to a novel continuous cylinder type volatile organic compound absorbing method. In an uninterrupted continuous running process, a cylindrical cylinder adsorbs VOCs gas passing through an adsorbing area of a zeolite molecular sieve and then exhausts purified air. Meanwhile, little VOCs-containing gas enters into a heater through a fan, is heated to 180-210 DEG C and then enters into a desorption area of the cylinder, and concentrated VOCs gas is discharged. Meanwhile, little VOCs-containing gas at room temperature is introduced, and the last circle of zeolite material is cooled in a regenerating area and then is applied to the adsorbing area again for continuously adsorbing the VOCs gas. According to the method provided by the invention, the air purification and VOCs concentration are simultaneously performed, the concentration of the concentrated VOCs gas is high, the volume is small, and thus the cost of process equipment is lowered; the adsorbing material is subjected to automatic regenerating treatment and is reusable, so that the use efficiency is increased, and the cost and the resource are saved.

Description

A kind of novel continuous cylinder type absorbs the method for VOC
Technical field
The present invention relates to a kind of method that novel continuous cylinder type absorbs VOC, belong to technical field of air purification.
Background technology
VOC is called for short VOCs, is a kind of mixed gases, and having volatility is to cause the main cause of chemistry haze, and environment and life and health are had ill effect.The equipment of purifying VOCs gas is a lot of at present, such as runner type adsorbent equipment, cylinder type adsorbent equipment, separates membrane treatment appts, catalytic combustion system etc., but purification efficiency is not quite similar, and wherein cylinder type adsorbent equipment purification efficiency is more than 93%.The cylinder district part of cylinder type adsorbent equipment is cylindrical, interior does sorbing material with zeolite.Wherein, the method for operation of cylinder is different, and clean-up effect is the most different.The present invention designs a kind of method that novel continuous cylinder type absorbs VOC, it is possible to achieve work continuously, constant absorption purify air, are the methods of the VOCs gas contained in a kind of input cost purification air low, high efficiency.
Summary of the invention
The present invention provides a kind of method that novel continuous cylinder type absorbs VOC, purpose is not only raising purification efficiency, also VOCs gas can be concentrated, internal sorbing material is carried out reclaiming, it is possible to achieve work continuously, constant absorption purify air.
For reaching this purpose, the present invention by the following technical solutions:
Cylinder continuously runs without resting, and sorbing material district when gas is cleaned by cylinder is called adsorption zone；The VOCs that in cylinder, sorbing material is adsorbed be concentrated resolve attached out time the sorbing material district that passed through be called desorption district；Being passed through regeneration gas makes regneration of adsorbent material use, and the sorbing material district that now gas is passed through is called renewing zone.Realize cylinder continuous operation free of discontinuities, and on-fixed sorbing material correspondence FX.
Beneficial effects of the present invention:
1. gas purification and VOCs concentrate and carry out improving purification efficiency and productivity simultaneously；
2. adding VOCs concentration process, the VOCs gas concentration after concentration is high, and volume is little, reduces the cost of rear end processing equipment at end；
3. renewing zone makes absorbing material reuse, improve service efficiency, cost-effective, economize on resources.
Accompanying drawing explanation
Fig. 1: continous way cylinder type absorbs VOCs gas schematic flow sheet.
Detailed description of the invention
Detailed description of the invention is as shown in Figure 1.Column type cylinder (1) uninterruptedly continuously runs.Gas (2) containing VOCs enters the adsorption zone (4) of zeolite molecular sieve by pre-treatment fan (3), after absorption VOCs, air (5) about 300 CMM after purification is discharged.Meanwhile, being passed through a small amount of about 9 CMM gas (6) containing VOCs and arrive heater (8) via fan (7), the desorption district (9) entering cylinder after heating the gases to 180 DEG C-210 DEG C is changed into the VOCs gas (10) of small size high concentration and discharges.Meanwhile, it is passed through a small amount of about 9 CMM gas (6) (room temperature) containing VOCs in renewing zone (11) by the zeolitic material cooling of a upper circulation, resolves through supercooling and can continue to adsorb VOCs composition when attached zeolite module is re-applied to treatment region.Three above process is carried out simultaneously, and zeolite module is not fixing belongs to a certain district.

Claims (1)

1. the present invention relates to a kind of method that novel continuous cylinder type absorbs VOC, it is characterized in that: column type cylinder (1) uninterruptedly continuously runs, the gas containing the VOCs adsorption zone (4) by zeolite molecular sieve, after absorption VOCs, discharges the air (5) after purifying；Simultaneously, it is passed through a small amount of (the 3% for the treatment of capacity) gas (6) containing VOCs via fan (7) to heater (8), enter the desorption district (9) of cylinder after heating the gases to 180 DEG C-210 DEG C, be changed into the VOCs gas (10) of small size high concentration and discharge；Meanwhile, the zeolitic material cooling of a upper circulation, the zeolite module after supercooling desorption can be continued when being re-applied to treatment region to adsorb VOCs composition by the gas (6) (room temperature) containing VOCs being passed through a small amount of about treating capacity 3% in renewing zone (11)；Purify air at work, process simultaneously and reclaim sorbing material, it is achieved while high-efficient purification, it is achieved the regeneration of sorbing material automatically processes.
