Description
Technical field
The invention belongs to VOCs waste treatments field, the exploitation of more particularly to new concentration runner and its in VOCs is administered
Application.
Background technology
In the current industrial production era, the discharge of industrial source VOCs waste gas is ecological deterioration, haze weather and PM2.5
The primary pollution source of environmental issue one of of the exceeded grade of granule concerning national economy.But presenting strong wind the discharge of industrial waste gas more
The characteristics of amount, low concentration, this proposes a primary difficult problem for follow-up waste gas treatment process：How this is fast and efficiently concentrated
A little emissions？The country, adopts active carbon adsorption this field more, is typically with several activated carbon adsorption beds parallel operations,
Equipment is huge, takes up an area more.And the defect of the adsorption capacity and mechanical strength due to activated carbon, the service life of equipment is short, frequently
Numerous adsorbent of changing increased operating cost and the inconvenience for operating to enterprise.
This project is directed to above-mentioned sciences problems, and foreign advanced technology, experience, in conjunction with the achievement in research that seminar is newest
New functional fiber adsorbing material is developed, the concentration runner for having independent intellectual property right is designed, and which is applied in industry
The aspects such as the concentration of waste gas VOCs, recovery, taste removal, deodorization, environmental improvement.The production for having filled up domestic association area is blank.

Specific embodiment
By the following examples feature of present invention and other correlated characteristics are described in further detail, in order to the same industry
The understanding of technical staff：

Driving equipment of the machine as concentration runner, completes automotive lacquer, wind-force using benzene,toluene,xylene solvent and nitrogen cylinder and sends out
The simulation of the paint such as electric blade baking vanish tail gas workshop discharge gas is investigating the concentrated effect of self-control novel rotating wheel.Company at a time when
One, Tianjin wind power generation blade paint spray booth tail gas processing item is accepted, integration project does this test.Test result with toluene
As a example by：Test process has investigated the clearance of different cocnentration factors and different runner rotating speed Toluene tail gas.
Toluene removal rate different cocnentration factors under, stable induction air flow ratio 2m s are first investigated-1, inlet gas concentration 100mg M-3、
25 DEG C of intake air temperature, relative humidity RH=50%, rotating speed 3.5r h-1, regeneration 180 DEG C of air temperature.When cocnentration factor from 5 improve to
When 15, regeneration air quantity is reduced to original 1/3rd accordingly, and this greatly reduces the process load of subsequent cell, but regenerates
The reduction of air quantity means the reduction for being desorbed total amount of heat, while regenerating wind diffusion rate and heat transfer factor also with regeneration wind speed
Reduction and reduce, cause be desorbed area rear end local shortage of heat, have impact on adsorbent reactivation and system purification efficiency, therefore first
Benzene clearance is down to 88% from 98.2%.Cocnentration factor increase is desorbed wind speed and reduces accordingly, and therefore optimum speed also should be synchronous
Reduce, and rotating speed is more than optimum speed in practical operation, therefore temperature curve shows as only being desorbed area's leading portion small part energy quilt
Regeneration temperature is heated to, desorption is insufficient to result in the relatively low of removal efficiency.When cocnentration factor is reduced to 6 from 14, toluene goes out
Mouth concentration is only from 4.7mg m-3It is reduced to 1.5mg m-3, but the toluene concentration after concentrating is from 1345mg m-3It is down to 576mg
m-3, so low concentration is unfavorable for that subsequent combustion or condensing unit are processed.Therefore, guaranteeing the clearance premise of default
Under, reasonable selection cocnentration factor it is critical that, the optimal cocnentration factor of this test final choice is 14.
Absorption is synchronously carried out in runner cycle of operation with being desorbed, and both affect each other and together decide on going for runner
Efficiency is removed, and the size of rotating speed means that absorption and desorption time length change.The toluene that we have been investigated under different rotating speeds goes
Except rate, stable induction air flow ratio 2m s-1, inlet gas concentration 100mg M-3, 25 DEG C of intake air temperature, relative humidity RH=50%, regeneration
180 DEG C of air temperature, cocnentration factor 14.When rotating speed is from 2.2r h-1Bring up to 3.5r h-1When, toluene removal rate is risen to from 85.4%
96.1%, show to improve with the raising of rotating speed in the rotating speed interval clearance, this is because when rotating speed is too low, adsorption zone is stopped
Stay overlong time and cause adsorbate (pollutant) saturation or penetrate, therefore improve the faster rotational speed replacement of adsorbent, it is ensured that
Adsorbent leaves adsorption zone before penetrating.And in 3.5-6.5r h-1Rotating speed is interval, toluene removal rate with rotating speed raising and
Less than 90% is down to, this is because rotating speed is too high, desorption area's time of staying is too short, recovery time deficiency causes desorption not exclusively,
And then affect adsorption efficiency.Optimum speed is substantially absorption and the control of desorption time, to realize that runner clearance is maximum.Real
When border is applied, because receiving multifactor impact, runner rotating speed to can be controlled in an interval value for coordinating other specification change.In this test,
As rotating speed 2.6-5.5r h-1When, the removal rates of system change less and equal can maintain more than 90%, the final selection of this test
Optimum speed is 3.5r h-1.
