Large oil gun for cremator
The invention relates to a large oil gun for a cremator. An oil nozzle consists of a center oil tube and a peripheral air tube sleeved on the periphery of the center oil tube; the front end face of the peripheral air tube is hermetically connected with the front end of the outer wall of the center oil tube; a center oil circuit is arranged in the center oil tube; a gap is reserved between the peripheral air tube and middle back part of the center oil tube, so that a peripheral air channel is formed; the tube wall of the front end of the center oil tube is provided with one or more injection air holes which are communicated with the center oil circuit and the peripheral air channel. The injection air holes are communicated with the center oil tube and the peripheral air tube, and high-speed air current in the peripheral air tube can form a negative-pressure area at the front end of the center oil tube, so that oil flow in the center oil tube can be quickly absorbed to the front end of the center oil tube, and is sprayed out of the oil nozzle after being atomized. 1. a cremator large oil gun, in from the center and the periphery of the central oil pipe a peripheral pipe, characterized in that the front end face of the peripheral pipe of the outer wall of the central oil pipe together is closed, the oil in the central oil pipe as the center, the periphery of the central oil pipe in the air gap is left between the periphery of the rear part of the air a, on the tube wall of the front end of the central oil pipe is provided with one or a plurality of communication center oil passage and the periphery of the injection hole. 2. The fuel injector according to Claim 1, characterized in that pin shoots the blowhole the inner wall of the oil pipe at the centre of the inclined direction toward the nozzle. 3. A cremator large oil gun, comprising a front end of the fuel injector, and the fuel injector connected to an oil feed pipe and the gas supply pipe, the fuel injector is composed of a central oil pipe and is sleeved on the periphery of the central oil pipe a peripheral pipe, the fuel injector the periphery of the front end face of the outer wall of the central oil pipe together with the Love is closed, the inside of the central oil pipe for the central oil passage, the periphery of the fuel tube and the center of the oil pipe is formed in a clearance is left between the periphery of the rear part of the air passage; said oil supply pipe passes through the air supply tube, the head of the oil supply pipe is inserted into the center of the assembly and the fuel injectors at the interface at the rear end of the oil pipe, a water supply pipe the periphery of the head of the rear end of the nozzle at the interface of the gas pipe, which is characterized in that the centre of the oil injection nozzle is arranged on the pipe wall of the front end of the oil pipe is provided with one or a plurality of communication center oil passage and the periphery of the injection hole. 4. Spray gun according to Claim 3, characterized in that in the central oil pipe leading shoots the blowhole the inner wall of the inclined direction toward the nozzle opening. 5. Spray gun as in Claim 3 or Claim 4, characterized in that the tail end of the gas supply pipe is closed in on the outer wall of the oil supply line, the tail end of the oil supply pipe from the gas supply pipe passes through the tail end of the and is connected with a fuel feeding valve, on the side wall of the tail of the gas supply pipe is connected with a gas supply valve. 6. Spray gun according to Claim 5, characterized in that oil supply line can be detected is also arranged on the gas pressure in the pressure gauge.
