Section, with the vertical section be responsible for and be connected to, and the bend loss of the connection horizontal segment and the vertical section.
The utility model has the following beneficial effects:
Hydrolysis exhaust gas is emitted into wastewater disposal basin and realized and is absorbed, or utilizes existing wastewater disposal basin, realizes hydrolysis waste gas absorption；
It is small in size, using flexible, without increasing new equipment, depth of building do not influenced, the effect of spray-absorption can be realized
Fruit.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of hydrolysis of urea waste gas collection device described in the utility model embodiment；
Fig. 2 is the top view of Fig. 1.
In figure,
1, wastewater disposal basin；2, admission line；3, collector；4, it is responsible for；5, secondary pipe；6, circular hole.
Specific embodiment
Below by specific embodiment and in conjunction with attached drawing, the utility model is further described in detail.
As shown in Figs. 1-2, a kind of hydrolysis of urea waste gas collection device of the utility model embodiment, including 3 He of collector
Admission line 2.Collector 3 is placed horizontally in 1 inside of wastewater disposal basin and is located at liquid level hereinafter, collector 3 includes supervisor 4 and fixes
In the more pipes 5 being responsible for 4 bottoms and being arranged in juxtaposition with same intervals L, supervisor 4 is connected to time 5 contact position of pipe, every pipe 5
On be uniformly provided with multiple circular holes 6.2 one end of admission line is connected to 4 top of supervisor, another to be connected to hydrolysis of urea exhaust gas.
The supervisor 4 of collector 3 and Duo Gen pipe 5 constitute time structure, and exhaust gas enters collector 3 by admission line 2, first
It is introduced into supervisor 4, since supervisor 4 is connected to more pipes 5, exhaust gas flows into each secondary pipe 5 by supervisor 4 and flows in secondary pipe 5,
Again by the multiple circular holes 6 opened up on time pipe 5, the waste water that exhaust gas is accessed absorbs.
To guarantee that exhaust gas preferably can enter each secondary pipe 5 from supervisor 4, more times pipe 5 is vertically fixed on supervisor 4.
Further, L is divided between on secondary pipe 5 between two neighboring circular hole 6, on adjacent twice pipes 5 at same position
It is divided into L between two circular holes 6, the interval in time structure between two neighboring circular hole 6 in this way is equal as L, so that exhaust gas
After from supervisor 4 into each secondary pipe 5, it can uniformly be discharged into waste water and be absorbed from each circular hole 6.Meanwhile it also protecting
Gas is demonstrate,proved when impacting collector 3, impact force is dispersed to everywhere, interfering with each other for gas will not occur, to mention
High working efficiency, also ensures in not managed inside collector 3 and retains gases affect.
Further, K, outermost time 5 center of pipe are divided between on secondary pipe 5 between 1 inner wall of outermost mother rib lateral rotundum 6 and wastewater disposal basin
It is divided into K between 1 inner wall of wastewater disposal basin, time structure becomes rectangular in this way, cooperates the circular hole being evenly arranged, gas can be more
Uniform diverging flow.
Four pipes 5 that collector 3 is included supervisor 4 and is fixed on side by side on supervisor 4 with interval L in the present embodiment.
Further, 2 one end of admission line is connected to 4 top centers of supervisor, to ensure that gas generates equilibrium to collector 3
Air pressure, enable gas evenly dispersed to surrounding from middle part.
In the present embodiment, admission line 2 includes the horizontal segment being connected to hydrolysis of urea exhaust gas, and it is vertical to be connected to supervisor 4
Section, and the bend loss of connection horizontal segment and vertical section.
Further, in order to improve the service life of collector 3, the corrosion of exhaust gas and waste water is avoided, collector 3 is not using
Rust steel material.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
