Abstract
The utility model relates to a durable denitration spray gun, including the rifle body, inlet, atomizing air mouth, cooling air entry and nozzle. The rifle body is the cover tubular construction, and including liquid pipe, trachea and cooling tuber pipe, during the liquid pipe inserted the trachea, the trachea passed through sealing flange fixed connection in inserting the cooling tuber pipe between trachea and the cooling tuber pipe. Inlet and liquid union coupling, the atomizing air mouth is connected with the tuber pipe, cooling air entry and cooling air union coupling. The denitration spray gun is equipped with the protection tube, and the protection tube passes through adapter sleeve and installs the nozzle one end at the rifle body. The material of protection tube is inertia pottery carborundum. The utility model discloses an at denitration spray gun installation protection tube, the high temperature that has improved the spray gun is able to bear or endure oxidizability and abrasion resistance ability, has prolonged the life of denitration spray gun, has optimized the atomization effect of spray gun.
Description
Technical field
The utility model belongs to waste gas pollution control and treatment special equipment technical field, relates to the out of stock equipment of a kind of flue gas, is specifically related to a kind of durable denitration spray gun.
Background technology
Denitration spray gun is the nucleus equipment of denitrating system, and spray gun Performance and quality plays decisive role to the denitration rate of whole denitration engineering, operating cost, the escaping of ammonia and service life etc.Spray gun atomizing effect directly affects the mixability of denitration reaction agent and flue gas and the time of staying of reactant.
Common metal material spray tip is applied in wind speed all faces rapid wear problem up to the circulating fluidized bed boiler separator porch of 20-30m/s, general spray gun is at high temperature, at a high speed, all can not to exceed half a year even shorter service time in the flue gas of high dust, the situation of nozzle wear within three months, is namely there is in a lot of use producers reaction denitration spray gun in use, cause atomization badness, denitration efficiency declines, reducing agent utilization rate is low, adds denitration cost, decreases the economic benefit of enterprise.
Utility model content
The purpose of this utility model is to provide a kind of durable denitration spray gun, to improve high-temperature oxidation resistance and the abrasion resistance properties of spray gun, extends the service life of denitration spray gun, optimizes the atomizing effect of spray gun.
The technical solution of the utility model is: durable denitration spray gun, comprises rifle body, inlet, atomizing space gas port, cooling air inlet and nozzle.Rifle body is sleeve structure, comprises liquid pipe, tracheae and cooling duct, and liquid pipe inserts in tracheae, and tracheae inserts in cooling duct, is fixedly connected with between tracheae and cooling duct by sealing flange.Inlet is connected with liquid pipe, and atomizing space gas port is connected with airduct, and cooling air inlet is connected with cooling duct.Denitration spray gun is provided with protection tube, and protection tube is arranged on one, the nozzle of rifle body by joint sleeve.
The material of protection tube is inactive ceramic carborundum.Denitration spray gun is provided with sleeve pipe, and sleeve pipe is provided with mounting flange, on furnace wall, fixedly mount denitration spray gun.
Inactive ceramic carbofrax material is made high temperature more than 2000 degrees Celsius, and Mohs' hardness is 9.5 grades, is only second to diamond the hardest in the world, has fabulous high temperature resistance to oxidation character, is suitable for being applied in the denitration environment of high temperature.Protection tube inert ceramic material is one-body molded; metal denitration spray gun is mounted on anterior by joint sleeve; denitration spray gun is surrounded wherein, makes the hardware of spray gun directly and the smoke contacts of high temperature, high speed and high dust, alleviate the wearing and tearing of exhaust gas dust to spray gun.The utility model, by installing protection tube in denitration spray gun, improves high-temperature oxidation resistance and the abrasion resistance properties of spray gun, extends the service life of denitration spray gun, optimize the atomizing effect of spray gun, is conducive to reducing denitration cost, increases Business Economic Benefit.
