The utility model discloses a kind of Pneumatic extension spray gun, comprise nozzle and gun shot, described gun shot is hollow structure, the head of described gun shot is connected with nozzle, the afterbody of described gun shot is provided with water inlet and air inlet, wherein, described gun shot is provided with air-leg, one end of described air-leg is fixed on gun shot by nut and connecting plate, the other end is connected with the piston rod of cylinder, described cylinder is fixed on U-shaped fixed head, and the bottom of described U-shaped fixed head is provided with the first fixed head, and the side of described U-shaped fixed head is provided with the second fixed head.The utility model by installing air-leg and cylinder additional on gun shot, gun shot is driven to carry out telescopic adjustment, thus both can avoid spray gun too short-range missile cause injection of reducing agent on built-in pipe, cannot interact with high-temperature flue gas and affect out of stock object, spray gun can be avoided again oversize and very quick-wearing, and at spray gun, the used time does not exit in stove in time, significantly extends the bulk life time of spray gun.
Description
Technical field
The utility model relates to a kind of spray gun, particularly relates to a kind of Pneumatic extension spray gun.
Background technology
At present, because the operating temperature of SNCR denitrification spray gun is higher, in boiler, flue gas flow rate quickly, and in flue gas, carry a large amount of dust secretly, wearing and tearing for spray gun are also very severe, and spray gun in the past cannot adjust due to length, cause the end nozzle part of spray gun to be worn very soon and burn.When field working conditions or boiler wall thickness be designed with come in and go out on a small quantity time, due to flue gas flow rate in boiler quickly, flue-gas temperature up to 850-1100 DEG C, and carries a large amount of dust secretly in flue gas.The long words of the built-in length of spray gun then nozzle will soon be worn or burn, too short, reducing agent cannot be sprayed in burner hearth.In boiler running process, spray gun is burnt, and loses out of stock function, and in boiler operatiopn, spray gun cannot be changed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Pneumatic extension spray gun, telescopic adjustment can be carried out to the spray gun length putting in boiler, both can avoid spray gun too short-range missile cause injection of reducing agent on built-in pipe, cannot interact with high-temperature flue gas and affect out of stock object, spray gun can be avoided again oversize and very quick-wearing, significantly extend the bulk life time of spray gun.
The utility model is solve the problems of the technologies described above the technical scheme adopted to be to provide a kind of Pneumatic extension spray gun, comprise nozzle and gun shot, described gun shot is hollow structure, the head of described gun shot is connected with nozzle, the afterbody of described gun shot is provided with water inlet and air inlet, wherein, described gun shot is provided with air-leg, one end of described air-leg is fixed on gun shot by nut and connecting plate, the other end is connected with the piston rod of cylinder, described cylinder is fixed on U-shaped fixed head, the bottom of described U-shaped fixed head is provided with the first fixed head, the side of described U-shaped fixed head is provided with the second fixed head.
Above-mentioned Pneumatic extension spray gun, wherein, be arranged with hollow steel tube outside described gun shot, described hollow steel tube is fixedly linked by flange and gun shot, described hollow steel tube is formed with female adapter, and the junction of described flange and gun shot is welded with seal head and sealing plate.
Above-mentioned Pneumatic extension spray gun, wherein, the number of described water inlet and air inlet is multiple, and described multiple water inlet and air inlet are spacedly distributed.
The utility model contrast prior art has following beneficial effect: the Pneumatic extension spray gun that the utility model provides, by installing air-leg and cylinder on gun shot additional, gun shot is driven to carry out telescopic adjustment, thus both can avoid spray gun too short-range missile cause injection of reducing agent on built-in pipe, cannot interact with high-temperature flue gas and affect out of stock object, spray gun can be avoided again oversize and very quick-wearing, and do not exit in stove at spray gun, significantly extends the bulk life time of spray gun the used time in time.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the utility model Pneumatic extension spray gun structure schematic diagram.
Refer to Fig. 1, the Pneumatic extension spray gun that the utility model provides comprises nozzle 1 and gun shot 2, described gun shot 2 is hollow structure, the head of described gun shot 2 is connected with nozzle 1, the afterbody of described gun shot 2 is provided with water inlet 10 and air inlet 11, wherein, described gun shot 2 is provided with air-leg 7, one end of described air-leg 7 is fixed on gun shot 2 by nut 14 and connecting plate 15, the other end is connected with the piston rod of cylinder 6, described cylinder 6 is fixed on U-shaped fixed head 3, the bottom of described U-shaped fixed head 3 is provided with the first fixed head 13, the side of described U-shaped fixed head 3 is provided with the second fixed head 12.
The Pneumatic extension spray gun that the utility model provides, wherein, hollow steel tube is arranged with outside described gun shot 2, described hollow steel tube is fixedly linked by flange 5 and gun shot 2, described hollow steel tube is formed with female adapter 4, the junction of described flange 5 and gun shot 2 is welded with seal head 8 and sealing plate 9.The number of described water inlet 10 and air inlet 11 can be multiple, and described multiple water inlet 10 and air inlet 11 are preferably spacedly distributed, to control pressure and the water outlet of spray gun better.
The Pneumatic extension spray gun that the utility model provides, specific works process is as follows: to be P >=5bar by quick connector access filter impurity in pressure regulator valve removing source of the gas and water smoke and be adjusted between 3 ~ 5bar by gas pressure outside supply gas pressure, then accesses magnetic valve and accesses flow speed control valve again and be finally connected with two imports of cylinder.Electromagnetic valve coil obtains electric, and cylinder 6 shifts working position (i.e. anteposition) gun spraying onto spray gun.Electromagnetic valve coil dead electricity, cylinder is reduced to rear position spray gun, and spray gun should stop spraying (spray gun distance of stretch out and draw back 300mm).
The Pneumatic extension spray gun that the utility model provides also can arrange limitation travel switch and carry out spacing.When spray gun is raised to working position (i.e. anteposition), spacing luminous tube is bright.When spray gun is retracted into return (namely position), spacing luminous tube is bright.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
