Abstract
The utility model is related to a kind of pair of air port fume hood, including cabinet and air exhauster, air exhauster is installed at the top of cabinet, air exhauster connects exhaust duct, an outer end for bypassing exhaust duct is connected by pipe joint on exhaust duct, the bypass exhaust duct gos deep into fume hood from the top of fume hood or side wall, and inner in bypass exhaust duct installs bypass blower fan and wind scooper, and the bypass exhaust duct is Universal pipe or the telescoping tube fixed by Universal arm.This fume hood includes two-way air draft, is all the way main air draft, is all the way auxiliary air draft；Main air draft is located at top, and the power of main air blower is big；Air draft is aided in use small blower fan, power is small, bypass exhaust duct is Universal pipe, can arbitrarily it move, by bypass air draft wind scooper close to reaction vessel, directly, completely, rapidly absorb poisonous reacting gas, the gas run away can also be siphoned away by the air draft at top, dual fail-safe, it is ensured that the safety of experiment operator.
Description
Technical field
The utility model belongs to fume hood field, is related to air port, especially a kind of pair air port fume hood.
Background technology
General fume hood only one of which air port, is located at the top of fume hood.The shortcoming of this structure design is：1st, air port from
Toxic gas reactor is too remote, it is impossible to which quick whole siphons away toxic gas, and experiment operator can suck a part of poisonous
Gas；2nd, tuyere position can not be adjusted；3rd, the noise of big blower fan is big.
The utility model is based on evaluating catalyst reactor and designed, and is reacted when evaluating Catalytic Hydrogenation of Nitrobenzene with reactor
When, product has the toxic gases such as NO, NO2.Because reactor is too remote apart from blower fan, operated in fume hood, open anti-
When answering kettle, because people is nearer from reactor, also can more or less suction part toxic gas, if things go on like this, to operator's body
Health is unfavorable.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part to be easy to regulation there is provided one kind, for experiment behaviour
Make double air port fume hoods that personnel provide two kinds of selections.
The utility model solves the technical scheme that is used of technical problem：
A kind of pair of air port fume hood, including cabinet and air exhauster, air exhauster, air exhauster connection row are installed at the top of cabinet
Airduct, an outer end for bypassing exhaust duct is connected on exhaust duct by pipe joint, the bypass exhaust duct from the top of fume hood or
Side wall gos deep into fume hood, and inner in bypass exhaust duct installs bypass blower fan and wind scooper, and the bypass exhaust duct is universal
Pipe or the telescoping tube fixed by Universal arm.
Moreover, the exhaust duct outer end insert a toxic gas tourie in, be loaded with tourie can dissolve or
The solution reacted with toxic gas.
Advantage of the present utility model and good effect are：
1st, this fume hood includes two-way air draft, is all the way main air draft, is all the way auxiliary air draft；Main air draft is located at top, main
The power of blower fan is big；Air draft is aided in use small blower fan, power is small, bypass exhaust duct is Universal pipe, can arbitrarily move, will bypass
The wind scooper of air draft close to reaction vessel, directly, completely, rapidly absorb poisonous reacting gas, the gas run away can also be pushed up
The air draft in portion is siphoned away, dual fail-safe, it is ensured that the safety of experiment operator.
2nd, the exhaust duct of this fume hood is not directly communicated to outdoor, but in one toxic gas tourie of insertion, prevents poisonous
Gas leak is into outdoor air, environmental protection.
Brief description of the drawings
Fig. 1 is the structural representation of this fume hood.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch
The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
A kind of pair of air port fume hood, including cabinet 5 and air exhauster 2, air exhauster, air exhauster connection are installed at the top of cabinet
Exhaust duct 1.
Innovative point of the present utility model is：
1st, an outer end for bypassing exhaust duct 7 is connected by pipe joint 6 on exhaust duct, the bypass exhaust duct is from fume hood
Top or side wall go deep into fume hood, and inner in bypass exhaust duct installs bypass blower fan 3 and wind scooper 4.The bypass air draft
Manage the telescoping tube fixed for Universal pipe or by Universal arm.
2nd, the outer end of the exhaust duct is not directly communicated to outdoor, but in one toxic gas tourie 8 of insertion, in tourie
Inside it is loaded with the solution that can dissolve or reacted with noxious material.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of utility model design is not departed from, various modifications and improvements can be made, these belong to this reality
With new protection domain.
