Abstract
The invention discloses a laboratory solid particle processing method. The laboratory solid particle processing method comprises the following steps: collecting first laboratory gas, wherein the first laboratory gas contains solid particles; primarily filtering the solid particles in the laboratory gas to obtain second laboratory gas; detecting an instant content of solid particles in the second laboratory gas, and when the instant content is higher than /equal to a preset threshold value, primarily filtering the second laboratory gas; when the instant content is lower than the preset threshold value, secondarily filtering the second laboratory gas. By the laboratory solid particle processing method, the solid particle content of the laboratory exhaust gas can reach a level which is harmless to organisms and friendly to the environment at a low cost.
Description
Technical field
The present invention relates to the laboratory technique field, relate in particular to a kind of laboratory solid particle processing method.
Background technology
The waste gas, waste water, the dust that produce in the laboratory all might cause than havoc environment, and in the prior art, laboratory exhaust gas, waste water, dust all are separately to process, and adopt the mode of separately processing waste gas, waste water, dust can improve treatment effeciency undoubtedly.In the process that the dust in the waste gas is processed, the laboratory exhaust gas that at first will comprise dust sucks by exhaust system, then the dust in the waste gas is processed, there is a problem, if adopt screen pack that the dust in the laboratory exhaust gas is filtered, filter effect does not reach requirement, namely adopt after the part dust in the screen pack removal laboratory exhaust gas, still can not satisfy organism harmless and environmentally friendly, and expensive the filtering such as active carbon of employing, the firstth, price is higher, is that filter efficiency is lower in addition, demands urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of laboratory solid particle processing method, can low-cost make the solid particle in the laboratory exhaust gas reach harmless environmentally friendly to organism.
Propose a kind of laboratory solid particle processing method, comprising:
Gather the first laboratory gas, comprise solid particle in described the first laboratory gas;
For the first time filter solid particle in the gas of described laboratory, to obtain the second laboratory gas;
Detect the instant content of the solid particle of described the second laboratory gas, when described instant content greater than/equal pre-set threshold value, described the second laboratory gas is carried out the first time again filters; When described instant content less than pre-set threshold value, described the second laboratory gas is carried out the second time filters.
The instant content of the solid particle of described the second laboratory gas of described detection is specially: the instant content that detects the solid particle of described the second laboratory gas by corpuscular counter.
Adopting screen pack to carry out the first time filters.
Adopting activated-carbon device to carry out the second time filters.
Among the present invention, after at first adopting screen pack that the solid particle in the laboratory exhaust gas is filtered, by corpuscular counter the content of the solid particle that comprises in the laboratory exhaust gas is measured, until the content of the solid particle in the laboratory exhaust gas is lower than pre-set threshold value, then adopt active carbon filtering device to filter, thereby make the content of the solid particle in the laboratory exhaust gas reach harmless environmentally friendly to organism.
Description of drawings
Fig. 1 is the schematic flow sheet of a kind of laboratory solid particle processing method in the embodiment of the invention.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment:
As shown in Figure 1, Fig. 1 is the schematic flow sheet of a kind of laboratory solid particle processing method in the embodiment of the invention.
With reference to Fig. 1, a kind of laboratory solid particle processing method that the embodiment of the invention proposes comprises the steps:
S1, collection the first laboratory gas comprise solid particle in the first laboratory gas.
Particularly, by saying that in conjunction with dust arrester and air blast the first laboratory gas collecting in the laboratory arrives.
S2, the first time are filtered solid particle in the gas of described laboratory, to obtain the second laboratory gas.
Particularly, adopt screen pack to carry out the first time and filter, can filter out the most of solid particle in the gas of laboratory, thereby obtain the second laboratory gas.
S3, detect the instant content of the solid particle of the second laboratory gas by corpuscular counter, when instant content greater than/equal pre-set threshold value, the second laboratory gas is carried out the first time again filters; When instant content less than pre-set threshold value, the second laboratory gas is carried out the second time filters, filter for the second time and adopt activated-carbon device.
Among the present invention, at first adopt lower-cost screen pack to remove most of solid particle, after the content of solid particle has hanged down, adopt again activated-carbon device to filter out remaining part solid particle, make the gas that finally obtains harmless and environmentally friendly to organism.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
