Description
Technical field
The utility model relates to laboratory exhaust gas gathering-device, is specifically related to a kind of laboratory exhaust gas non-proliferation collection and treatment device.
Background technology
Laboratory can produce corresponding waste gas in daily operation process, the inorganic waste gases comprised in waste gas and organic exhaust gas, directly drains in air will certainly pollute surrounding enviroment as unprocessed, and can cause organic damage to human body.
Now conventional processing method installs fume hood in laboratory, tests in fume hood, and then to the collection process that the air of its inside is concentrated, this class methods start work, shutdown stops, considerably less by operating mode restriction, operates without the need to special messenger.But its mechanism is comparatively huge, equipment is complicated, and the waste gas that multiple fume hood is collected often is focused on by pipeline, complex treatment process, and use cost is higher, maintenance and repair inconvenience.Involve great expense, general laboratory can not all be equipped with this kind equipment.Another kind of way installs multiple gas skirt in laboratory, then carries out collection process to waste gas, but because the height of the height distance testing stand of collecting hood is higher, can not carry out collection process completely for the gas that the less volatility of waste gas is stronger.Particularly some small tests, waste gas produces less, and the experiment that reaction time is also short, large-scale treatment facility easily causes the wasting of resources on the contrary.
Any one no matter in such scheme is all adopt the way of negative pressure to collect the waste gas in laboratory, requires comparatively strict, mostly be corrosion resistant motor, the cost of the same equipment that adds to the blower fan producing negative pressure.Meanwhile, waste gas also causes certain corrosion to motor internal and corresponding kinematic mechanisms, has had a strong impact on the service life of equipment, has indirectly added the use cost of equipment.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of laboratory exhaust gas non-proliferation collection and treatment device.
The technical solution of the utility model is: a kind of laboratory exhaust gas non-proliferation collection and treatment device, comprise reaction pedestal, high-speed gas generating means is connected with below described reaction pedestal, described reaction pedestal offers looping pit, described reaction pedestal is also fixed with vertical rod, described vertical rod top is fixed with lateral connection bar, and the described lateral connection bar other end is fixed with gas skirt, and gas skirt is also connected with emission-control equipment by pipeline.
Further improvement of the utility model comprises:
Described high-speed gas generating means is without blade fan, and the looping pit position consistency on the described annular air outlet without blade fan and described pedestal.
Described high-speed gas generating means comprises a compressed gas source, and described compressed gas source is tightly connected by pipeline and described base bottom, and described compressed gas source is air compressor or compressed gas cylinder.
Described looping pit is also provided with catch net.
The utility model structure is simple, easy to use, the utility model produces circular curtain by utilizing high-speed gas, relatively airtight environment is formed to reaction compartment, avoid the excessive of waste gas, utilize gas skirt to carry out the collection of gas, other then collection enter emission-control equipment by pipeline simultaneously, utilize emission-control equipment to carry out absorption process to waste gas.Between gas skirt and emission-control equipment, no longer the devices such as blower fan are set, decrease the corrosion of waste gas to equipment.
Accompanying drawing explanation
Structural representation of the present utility model.
In figure: 1, react pedestal, 2, high-speed gas generating means, 3, gas skirt, 4, emission-control equipment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of laboratory exhaust gas non-proliferation of the utility model collection and treatment device, comprise reaction pedestal, high-speed gas generating means is connected with below described reaction pedestal, described reaction pedestal offers looping pit, this looping pit can form circular curtain, reaction compartment and external environment condition are completely cut off in short-term, described reaction pedestal is also fixed with vertical rod, described vertical rod top is fixed with lateral connection bar, the described lateral connection bar other end is fixed with gas skirt, and gas skirt is also connected with emission-control equipment by pipeline.
Described high-speed gas generating means is without blade fan, and the looping pit position consistency on the described annular air outlet without blade fan and described pedestal.Utilize to coordinate with looping pit without blade fan and form circular curtain.
Described high-speed gas generating means also can select a compressed gas source, the structure that described compressed gas source is tightly connected by pipeline and described base bottom, and described compressed gas source can be air compressor or compressed gas cylinder.Higher experiment is required for reaction environment, the steel cylinder of compressed nitrogen can also be utilized to provide high velocity air, part nitrogen is filled with in reaction forward direction gas curtain, the air of its inside is discharged, it is made to form an inert environments, whole process has nitrogen to provide the source of the gas of gas curtain, and guarantee is isolated with extraneous air.
Described looping pit is also provided with catch net.
The utility model structure is simple, easy to use, the utility model produces circular curtain by utilizing high-speed gas, relatively airtight environment is formed to reaction compartment, avoid the excessive of waste gas, utilize gas skirt to carry out the collection of gas, other then collection enter emission-control equipment by pipeline simultaneously, utilize emission-control equipment to carry out absorption process to waste gas.No longer arrange the devices such as blower fan between gas skirt and emission-control equipment, decrease the corrosion of waste gas to equipment, the utility model is particularly suitable for the less experiment of single scale, be convenient to mobile, or the laboratory of fund condition deficiency uses.
The emission-control equipment of the utility model indication is prior art, can be the conventional existing absorption means such as organic solvent absorption, charcoal absorption, acid-base solution absorption.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
