Technical field
The present invention relates to the experimental laboratory air exhausting technical field, relate in particular to a kind of experimental laboratory air exhausting treatment system.
Background technology
The waste gas that produces in the laboratory, waste water, dust all might cause than havoc environment, in the prior art, laboratory exhaust gas, waste water, dust all is separately to process, adopt and separately process waste gas, waste water, the mode of dust can improve treatment effeciency undoubtedly, in the process that waste gas is processed, at first laboratory exhaust gas is sucked by exhaust system, then, by exhaust treatment system the waste gas of being extracted out by exhaust blower is carried out purified treatment, make it waste gas and become the gas that reaches discharge standard, the problem that this kind processing mode exists is, there is a certain amount of dust granules in the waste gas by the suction of air draft gas, these dust granules are processed not necessarily can process fully at the employing exhaust treatment system and are reached discharge standard, and treatment effeciency is lower, in addition, after these dust granules reach finite concentration or particle and reach certain particle diameter, can cause damage to the relevant apparatus in the exhaust treatment system, so that device is lower service life, demand urgently improving.
Summary of the invention
Problem for the prior art existence, the object of the invention is to propose a kind of experimental laboratory air exhausting treatment system, can effectively finish exhaust-gas treatment, and make the solid particle that comprises in the waste gas can be to environment unharmful and can not cause damage to emission-control equipment, thus the service life of extension device.
A kind of experimental laboratory air exhausting treatment system, comprise dust gathering arrester, air exhausting device, dust treatment plant, emission-control equipment, dust gathering arrester is communicated with air exhausting device, air exhausting device is communicated with dust treatment plant and emission-control equipment by twin valve, the import of twin valve is communicated with air exhausting device, an outlet of twin valve is communicated with emission-control equipment, and another outlet is communicated with dust treatment plant, and dust treatment plant is communicated with emission-control equipment;
Corpuscular counter is for detection of the instant content of solids, and described instant content back is fed to control device; When described instant content during greater than/the threshold values that equals to preset, control device control twin valve makes conducting between air exhausting device and the dust treatment plant, makes between air exhausting device and the emission-control equipment and closes; When described instant content during less than default threshold values, control device makes between air exhausting device and the dust treatment plant and cuts out by the control twin valve, makes conducting between air exhausting device and the emission-control equipment.
Corpuscular counter is installed in the dust gathering arrester, for detection of the instant content of solids in the dust gathering arrester.
