Description
Technical field
The present invention relates to experimental laboratory air exhausting technical field, particularly relate to a kind of laboratory exhaust treatment system.
Background technology
In laboratory, the waste gas of generation, waste water, dust are likely to cause environment relatively havoc, existing skill
In art, laboratory exhaust gas, waste water, dust the most separately process, use separately process waste gas, waste water,
The mode of dust can improve treatment effeciency undoubtedly, during processing waste gas, first by laboratory
Waste gas is sucked by exhaust system, then, is carried out by the exhaust treatment system waste gas to being extracted out by exhaust blower
Purified treatment, is allowed to waste gas and becomes the gas reaching discharge standard, the problem that this kind of processing mode exists
Being to there is a certain amount of dust granules in the waste gas by air draft gas suction, these dust granules are useless in employing
Gas processing system carries out processing not necessarily can processing completely and reaches discharge standard, and treatment effeciency is relatively low,
It addition, after these dust granules reach finite concentration or granule reaches certain particle diameter, can be to exhaust-gas treatment
Relevant apparatus in system causes damage so that device is relatively low for service life, it would be highly desirable to improve.
Summary of the invention
The problem existed for prior art, it is an object of the invention to propose a kind of experimental laboratory air exhausting and processes system
System, can efficiently accomplish exhaust-gas treatment, and makes the solid particle comprised in waste gas will not to bad environmental and not
Understand and emission-control equipment is caused damage, thus the service life of extension device.
A kind of laboratory exhaust treatment system, including dust gathering arrester, air exhausting device, dust treatment plant, waste gas
Processing means, dust gathering arrester connects with air exhausting device, air exhausting device by twin valve and dust treatment plant and
Emission-control equipment connects, and the import of twin valve connects with air exhausting device, and an outlet of twin valve is even
Logical emission-control equipment, another outlet dust treatment plant, dust treatment plant and emission-control equipment
Connection；
Particle counter is for detecting the instant content of solids, and is fed to described instant content back control
Device；When described instant content is more than/is equal to the threshold values preset, control device and control twin valve, the row of making
Turn between wind apparatus and dust treatment plant, make to close between air exhausting device and emission-control equipment；Work as institute
When stating instant content less than the threshold values preset, control device, by controlling twin valve, makes air exhausting device and powder
Close between dirt processing means, make to turn between air exhausting device and emission-control equipment.
Particle counter is arranged in dust gathering arrester, the instant content of solids in detecting dust gathering arrester.
Particle counter is arranged in air exhausting device, the instant content of solids in detecting air exhausting device.
Particle counter is arranged in the main pipeline of connection air exhausting device and dust gathering arrester, is used for detecting in main pipeline
The instant content of solids.
In the present invention, first the content of the solid particle comprised in waste gas is detected, if solid particle
Content reaches certain threshold values, when emission-control equipment may cause damage or its discharge to bad environmental, then
Make waste gas first pass around dust treatment plant to remove dust therein, then carry out exhaust-gas treatment, right to avoid
Emission-control equipment causes damage, or works the mischief environment；If solid content does not reaches pre-in waste gas
If threshold values, the most directly carry out exhaust-gas treatment.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of laboratory exhaust treatment system that the embodiment of the present invention proposes.
Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention:
As it is shown in figure 1, Fig. 1 is the entirety of a kind of laboratory exhaust treatment system that the embodiment of the present invention proposes
