Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1；
Fig. 2 is the structural representation of the waste gas collection device of this utility model embodiment 1.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical solution of the utility model is described in further detail, but not structure
Paired any restriction of the present utility model.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of ventilated chamber utilizing bernoulli principle to process waste gas, including cabinet 1, described cabinet 1
Middle part be work space 2, be provided with waste gas collection device 3 in described cabinet 1, described waste gas collection device 3 includes successively
Centrifugal pump 31, ejector 32 and the reservoir 33 connected, described reservoir 33 is entered by a return duct 34 and centrifugal pump 31
Mouthful being connected, the first wide diameter tube section 35, first that described ejector 32 includes being sequentially connected with shrinks pipeline section 36, trunnion section 37 and the
Two shrink pipeline section the 38, second wide diameter tube sections 39, and the first described wide diameter tube section 35 is connected with the outlet of centrifugal pump 31, and described the
Two wide diameter tube sections 39 are connected with reservoir 33, and the first described contraction pipeline section 36 is provided with the waste gas connected with work space 2 and receives
Collector 4, described gas sampling pipe 4 is provided with the first check-valves 41.
In use, harmful gas such as sour gas is produced in work space 2, then start centrifugal pump 31, centrifugal
Pump 31, by the liquid suction centrifugal pump 31 in reservoir 33, then loops back in reservoir 33, in air-breathing by ejector 32
Position, is the position that a pipeline is less, according to Bernoulli equation:
P1+ρgz1+(1/2)ρv1 2=P2+ρgz2+(1/2)ρv2 2
In formula, P is pressure, and Z is height, and v is water flow velocity, and U is flow, constant.Therefore pressure differential
P2-P1=-ρ g+2U2(1/d1 2-1/d2 2)/3.14
Therefore the negative pressure produced mainly is determined by pipe diameter and height, and position is the highest, and pressure is the least, and negative pressure is the highest, diameter
The least, negative pressure is the highest, in the design, does not the most consider Z, therefore has only to consider the change of diameter, calculate circulation institute simultaneously
The flow needed.
So it is in negative pressure state in gas sampling pipe 4, by the waste gas suction ejector 32 in work space 2, and
Due to the construction features of ejector 32 own, mixing wastewater with air is highly uniform, can improve waste gas absorption clean-up effect.Meanwhile, originally
Embodiment Blower-free, when therefore running, noise is the least.
In the present embodiment, described first contraction pipeline section 36 is provided with chemical feed pipe 5, and described chemical feed pipe 5 is provided with the
Two check-valves 51.In waste gas treatment process, it is sour gas if to be processed, then chemical feed pipe 5 adds alkaline solution,
By being sufficiently mixed of ejector 32, reach medicament and purpose that waste gas fully reacts, it is not necessary to set up any mixed at reservoir 33
Close power set.
Preferably, described reservoir 33 is provided with the gas outlet pipe 6 for discharging purified gas, described gas
Body discharge pipe 6 is provided with demister 61.So can ensure that the purified gas of discharge is dried, reach discharging standards.
In circulation and course of reaction, due to machinery heat radiation and the impact of factor of exothermic heat of reaction and the impact of liquid level, reservoir 33
The temperature of liquid likely can rise, be provided with temperature probe 7 in therefore described reservoir 33, when temperature drift, pass through
Forced cooling measure or add water reach cooling maintain preferable reaction temperature system purpose.
In the present embodiment, described waste gas collection device 3 is arranged on the top of cabinet 1.Certainly waste gas collection device 3 is also
Do not repel the bottom being arranged on cabinet 1.
Above-described only preferred embodiment of the present utility model, all in spirit of the present utility model and spirit
Any amendment, equivalent and the improvement etc. made, within should be included in protection domain of the present utility model.
