Specific embodiment

The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model Shield range is not limited to the following embodiments.

A kind of easy device disposed for VOC gas with detection, as shown in Figure 1, including 3 He of activated carbon adsorption Rose Box The input terminal of air-exhausting duct 5, activated carbon adsorption Rose Box 3 is connect with waste gas inlet 1, and the input terminal of output end and air-exhausting duct 5 connects It connects, primarily efficient filter case 2 is equipped between activated carbon adsorption Rose Box 3 and waste gas inlet 1, as shown in Fig. 2, the primarily efficient filter case 2 The interior Honeycombed filtering sieve 21 being equipped with for filtering the particulate matter mixed in exhaust gas.

Honeycombed filtering sieve 21 is 200 mesh pore sizes: 0.0630mm --- standard mesh number.

The overflow hole 51 for sampling air flow is offered on air-exhausting duct 5, device further includes for will sample in air-exhausting duct 5 Air-flow is delivered to the overflow pipe 6 of setting position, and the input terminal of the overflow pipe 6 is connect with overflow hole 51.

Device further includes the detection terminal 7 for detecting VOC gas content in the air-flow of sampling, in addition, air-exhausting duct 5 is vertical Setting, overflow hole 51 are set to the middle and upper part on air-exhausting duct 5.

As shown in figure 3, activated carbon adsorption Rose Box 3 includes V-type module microporous particles 31, using initial effect filtering section+V-arrangement The process route of grain activated carbon adsorption carries out VOC processing, replaces simple filter cotton processing mode originally, can efficiently (90% with On) pollutant discharged in air is removed, it is discharged after reaching local environment standard.

Using frequency conversion fan 4, use (such as thread-changing process) under different working conditions can be met, to reach by variable frequency adjustment To energy-efficient effect.

The application when in use, without the VOC gas of disposition, is collected by main exhaust duct, into the first of VOC equipment Imitate Rose Box 2；Start the exhaust gas disposition of first of initial effect filtering section, the Honeycombed filtering sieve 21 in initial effect filtering section can remove useless In gas 1~5 μm particle (when resistance reaches setting value, taking-up is changed, and is used as disposable products, the replacement cycle about 2~ 3 months).Trapping interception is carried out to size particles object by initial effect filtering section, drops to influence of the weldering smoke particle to active carbon most It is low, it is ensured that the aeration of active carbon.

By the gas of primarily efficient filter, second activated carbon adsorption is started into activated carbon adsorption case 3 by air hose Exhaust gas disposes process, module (V-arrangement module microporous particles) is filled by the active carbon of special construction, under specific wind friction velocity (setting of 4# frequency conversion fan), reaches preferable Adsorption efficiency (usually 85-95%).

It is completely up to standard by the gas of disposition, it can be emitted by air-exhausting duct 5.

In 5 middle section of air-exhausting duct position on the upper side, an overflow hole 51 is opened, which is connected to master by overflow pipe 6 The overflow hole 8 in building corridor, the environmental regulatory persons of the floor detect the hand-held detection terminal device 7 of PID by VOC, can be taking human as It aperiodically detects and records whether the gas emitted reaches environmental standard, it is very convenient.
