Description
Technical field
The utility model relates to the equipment for denitrifying flue gas of thermoelectricity technical field of power generation, particularly, relates to a kind of equipment for denitrifying flue gas shower nozzle.
Background technology
At present, most thermal power plant equipment for denitrifying flue gas ammonia or mist shower nozzle, generally comprise head body, arranges gas flow in head body inside.In head body, be also provided with pad, the rear end in head body is provided with screw thread simultaneously.Wherein screw thread is as coupling part, for being connected with external equipment (such as pipeline); Be placed in the pad of head body inside, adopt the material preparation identical with head body, the aperture of its pad is for controlling the flow velocity of gas.The aperture of pad generally has
(8mm),
(10mm) and
(12mm), wherein
more conventional.
Although adopt pad aperture to carry out coutroi velocity in the design of shower nozzle, but in practical application, thermal power plant can not for changing pad and blowing out, so the flow velocity of ammonia is by the Valve controlling be arranged on outside flue in actual items, this makes the existent value of pad exist in name only, but because traditional design is always like this, the gasket design in shower nozzle is still habitually continued to use by most of producer.
Meanwhile, the part that is threaded designed in existing ammonia shower nozzle, its object mainly contains two aspects: the replacing being conveniently pad on the one hand, is the situation that the single damage of a shower nozzle appears in prevention on the other hand, changes the convenience of shower nozzle.But through the long-term observation in thermal power plant, in practice, there is not this type of situation.In the project that flue gas flow field is bad, ammonia injection device can by overall wear, and in the project that flue gas flow field is good, then overall ammonia injection device is intact, and the use of the part that is therefore threaded is little.
Further, the part that is threaded of existing shower nozzle is carried out after shower nozzle overall processing, adds workload and cost.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of light practicality, overall structure equipment for denitrifying flue gas shower nozzle that is simple, that easily process.
For achieving the above object, the utility model provides a kind of equipment for denitrifying flue gas shower nozzle, comprising: head body, is provided with gas flow in described head body, and does not arrange pad and screw thread in described head body, with external equipment by being welded to connect.
Further, the front end of described head body is jet segment, and the vertical sectional shape of described jet segment is isosceles trapezoid, and the upper base of isosceles trapezoid be described jet segment foremost.
Further, the rear end of described head body is linkage section, and the vertical sectional shape of described linkage section is rectangle, and described rectangle one end connects described jet segment, other end connecting pipe.
Further, welding manner is adopted to be connected between described linkage section with pipeline in flue.
Further, arrange in described head body conventional
or
aperture.
Further, described head body, its length is 50mm, is highly 40mm.
Further, described head body, its external diameter is 50mm.
Further, the length of described linkage section is 15mm.
Further, described shower nozzle is formed in one, and is laid in flue by welding.
Compared with prior art, the utility model has following beneficial effect:
The utility model shower nozzle has abandoned the pad and screw thread that tradition continues to use, and one-body molded when manufacturing, and by welding and other equipment connections, simple and practical, cost reduces; Further, profile is compared original spray ammonia nozzle and improve, reduction sprinkler height, length (height of former shower nozzle, length are 46mm, 59mm respectively), both sides excess stock of pruning, thus alleviate the weight of shower nozzle entirety.
The utility model has abandoned the pad and screw thread that tradition continues to use, and have adjusted profile, thus alleviates product weight, reduces processing cost and workload.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Fig. 1 is the structural representation of shower nozzle in the utility model one preferred embodiment;
Fig. 2 is the detailed dimensions schematic diagram of shower nozzle in the utility model one preferred embodiment;
Fig. 3 is the upward view of shower nozzle in the utility model one preferred embodiment;
In figure: head body 1, gas flow 2, jet segment 3, linkage section 4.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
As shown in Figure 1, for the equipment for denitrifying flue gas shower nozzle schematic diagram of the utility model one preferred embodiment, comprising: head body 1, in described head body, be provided with gas flow 2, and in described head body 1, pad and screw thread are not set, with external equipment by being welded to connect.
In another embodiment, the front end of described head body 1 is jet segment 3, and the vertical sectional shape of described jet segment 3 is isosceles trapezoid, and the upper base of isosceles trapezoid be described jet segment 3 foremost.
The rear end of described head body 1 is linkage section 4, and the vertical sectional shape of described linkage section 4 is rectangle, and described rectangle one end connects described jet segment 3, other end connecting pipe.
Described linkage section 4 adopts welding manner to be connected with between pipeline in flue.
The present embodiment shower nozzle has abandoned the pad and screw thread that tradition continues to use, and one-body molded when manufacturing, and by welding and other equipment connections, simple and practical, cost reduces.May be used for ammonia injection and also may be used for air gas mixture injection.
