Description
Technical field
The present invention relates to hydrolysis of urea gas absorption techniques fields, in particular to a kind of hydrolysis of urea gas sampling
Device.
Background technique
Denitrating flue gas refers to harmful substance NO contained in flue gas after high-temp combustionXThe technology of removing, including SCR and
Two kinds of major technique schools of SNCR, wherein SCR is the mainstream technology of denitrating flue gas.So-called SCR technology refers to province's coal in boiler
SCR reactor is set between device and air preheater, catalyst is installed in reactor, is sprayed into the flue cross section before reactor
Reducing agent (ammonia-containing gas), reducing agent and NOXIt reacts on catalyst surface and removes NOX。
It is by ammonia as reducing agent and NO during denitration reactionXReaction is to achieve the purpose that denitration.Denitrification reducing agent
Mainly there are liquefied ammonia, ammonium hydroxide and urea.At present there are mainly two types of urea technique for production of ammonia: urea pyrolysis and hydrolysis of urea technique.It is urinating
In plain hydrolysis process, it is mainly ammonia gas mixture that urea hydrolyser, which generates exhaust gas,.Traditional handicraft is absorbed ammonia using spray column
Become ammonium hydroxide, ammonium hydroxide is transported to Water Treatment workshop by waste water pump.This mode needs spray column higher, it is therefore desirable to increase
Add depth of building, also results in the maintenance work for increasing equipment.
Summary of the invention
To solve the above problems, utilizing secondary knot the purpose of the present invention is to provide a kind of hydrolysis of urea waste gas collection device
Configuration formula, which will hydrolyze exhaust gas and be emitted into wastewater disposal basin, to be absorbed.
The present invention provides a kind of hydrolysis of urea waste gas collection devices, comprising:
Collector is placed horizontally in inside wastewater disposal basin and is located at liquid level hereinafter, the collector is including supervisor and admittedly
The more pipes for being scheduled on the supervisor bottom and being arranged in juxtaposition with same intervals L, the supervisor are connected to the secondary pipe contact position,
Multiple circular holes are uniformly provided on every pipe；
It is connected at the top of admission line, one end and the supervisor, it is another to be connected to hydrolysis of urea exhaust gas.
As further improvement of the invention, more times Guan Jun are vertically fixed on the supervisor.
It is improved as of the invention further, is divided into L between managing between upper two neighboring circular hole for described time.
It is improved as of the invention further, is divided into L between managing for adjacent twice at upper same positions between two circular holes.
As further improvement of the invention, the described interval managed between upper outermost mother rib lateral rotundum and the wastewater disposal basin inner wall
For K.
Improved as of the invention further, between outermost time tube hub and the wastewater disposal basin inner wall between be divided into K.
As further improvement of the invention, the collector includes supervisor and is fixed on the master side by side with interval L
Four pipes on pipe.
As further improvement of the invention, described admission line one end is connected to supervisor's top center.
As further improvement of the invention, the admission line includes the horizontal segment being connected to hydrolysis of urea exhaust gas, with
The vertical section of supervisor's connection, and the bend loss of the connection horizontal segment and the vertical section.
The invention has the benefit that
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 embodiment of the present invention；
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
The present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.
As shown in Figs. 1-2, a kind of hydrolysis of urea waste gas collection device of the embodiment of the present invention, including collector 3 and air inlet
Pipeline 2.Collector 3 is placed horizontally in 1 inside of wastewater disposal basin and is located at liquid level hereinafter, collector 3 is including supervisor 4 and is fixed on master
4 bottom of pipe and more pipes 5 being arranged in juxtaposition with same intervals L, are responsible for 4 and are connected to time 5 contact position of pipe, on every pipe 5
It is even to offer 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 foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
