The existing boiler is single in denitration technology, denitration equipment is complex and unreasonable, the structure of a denitration spray gun device is complex, the installation, maintenance and disassembly processes are inconvenient, and after a denitration spray gun is deeply arranged in a hearth, the temperature in the hearth is extremely high, so that a nozzle at the head of the spray gun is easily burnt out, and denitration operation in the boiler is influenced.
The prior patent "201520227705.7" granted by the national intellectual property office is named as: the denitrator nozzle is characterized by comprising two hollow joints and a feed liquid pipe, wherein the two joints comprise a first joint and a second joint, the tail part of the second joint is embedded in the head part of the first joint, the head part of the second joint is installed in the nozzle joint, a nozzle head is installed at the top end of the nozzle joint, an air pipe for introducing high-pressure air is arranged on the first joint, the feed liquid pipe is arranged in the first joint and the second joint, the outlet of the feed liquid pipe is communicated with the nozzle head, and a nozzle core is arranged between the nozzle head and the head part of the second joint. "in the above technical means, the entire spray gun is composed of the first joint, the second joint, the nozzle head, the liquid pipe and other members, and the spray gun has a complicated structure and low sealing performance.
Disclosure of Invention
The utility model aims to provide a simple structure, it is convenient to dismantle, has cooling function and can improve the spray gun device on the interior denitrator of denitration efficiency.
The utility model discloses a task is accomplished like this, including the nozzle, its characterized in that: the spray gun pipe body wholly runs through and is fixed with on spray gun and the tube head the nozzle, the cooling tube cladding is in the spray gun pipe surface, the cooling tube import sets up in cooling tube upper portion, and the cooling tube mouthpiece sets up at cooling tube bottom end face, and the hasp links together and the cladding is outside the cooling tube with pre-buried outer tube. The nozzle head is provided with a straight-line-shaped spray hole.
The utility model discloses has following effect: the technical scheme is composed of a spray gun tube, a cooling tube, a pre-buried tube and a nozzle, and the whole structure is simple; and the outer surface of the lance pipe is coated with a layer of cooling pipe, and the bottom of the cooling pipe is provided with a cooling pipe mouthpiece so as to realize the cooling function of the nozzle and avoid the nozzle from being burnt. This spray gun device has a pre-buried outer tube in the outside cladding of cooling tube, and is equipped with the hasp on the pre-buried outer tube, and when maintaining or dismantling, pre-buried outer tube is pre-buried all the time within the furnace wall, only needs to open the hasp can take out the spray gun main part, convenient and fast. The nozzle head is provided with a linear spray hole, so that the spray area of the urea solution is increased, and the denitration efficiency is improved.

Description of the drawings: 8-3-1, a spray gun tube; 8-3-2. a cooling pipe; 8-3-3, cooling pipe inlet; 8-3-4, locking; 8-3-5, pre-burying an outer pipe; 8-3-6. cooling pipe blowing mouth; 8-3-7. a nozzle; 8-3-8, spraying holes.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 and 2, the spray gun device on the denitrator in the furnace comprises a spray nozzle 8-3-7, and is characterized in that a whole body of a pipe body 8-3-1 of the spray gun pipe penetrates through the spray gun, the spray nozzle 8-3-7 is fixed on a pipe head, the outer surface of the spray gun pipe 8-3-1 is coated with a cooling pipe 8-3-2, an inlet 8-3-3 of the cooling pipe is arranged at the upper part of the cooling pipe 8-3-2, a blow opening 8-3-6 of the cooling pipe is arranged at the lower bottom end face of the cooling pipe 8-3-2, and a lock 8-3-4 is connected with an embedded outer pipe 8-3-5 and is coated outside the cooling pipe 8-3-2. The pre-embedded outer pipe 8-3-5 is pre-embedded on the furnace wall, and the nozzle 8-3-7 extends into the hearth. When the spray gun is disassembled or maintained, the main body part of the spray gun can be drawn out only by opening the lock catch 8-3-4, and the installation is also the same, so that the spray gun is convenient and quick. The head of the nozzle 8-3-7 is provided with a linear spray hole 8-3-8, and the linear spray hole increases the spray area of the urea solution, thereby being more beneficial to improving the denitration efficiency.
When denitration is carried out in the furnace, steam in the steam power pipe provides power for the prepared urea solution with a certain concentration entering the spray gun pipe 8-3-1, so that the urea solution is sprayed into the hearth through the spray gun pipe 8-3-1 and the nozzle 8-3-7. Meanwhile, the steam in the steam cooling pipe is guided into the cooling pipe 8-3-2 through the cooling pipe inlet 8-3-3 and is blown out from the cooling pipe blow opening 8-3-6 to cool the nozzle 8-3-7 and avoid burning out.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
