Injection-type high atomized oil gun

Abstract

The invention discloses an injection-type high atomized oil gun and relates to the technical field of an apparatus. A key technology of 'providing a mixing cavity and a scale body' is adopted; an oil interface is fixed together with the rear end of an oil gun inner pipe; the oil gun inner pipe is fixed together with a hole on a rear-end end cap of an oil gun fixing pot head; the front end of the oil gun inner pipe is fixed together with the rear end of an inner short circuit through an inner metal hose; the front end of the inner short circuit is fixed together with a jet nozzle; a taper wall of the jet nozzle is fixed together with a rear end section of a mixing cavity; the rear end section of the mixing cavity at the front end of the jet nozzle is fixed together with the scale body; the rear end of the mixing cavity is fixed together with the front end of the outer short circuit; the rear end of the outer short circuit is connected with the front end of the metal hose; the rear end of the metal hose is fixed together with the front end of an oil gun outer pipe; the rear end of the oil gun outer pipe is fixed together with the front end of the oil gun fixing pot head; the oil gun fixing pot head is also fixed together with a gas interface through a pipeline. The injection-type high atomized oil gun is an oil gun of burning diesel oil to start a coal-fired thermal power plant boiler and stably burn at low load, is simple and delicate in structure, stable and reliable in effect, easy to manufacture and low in cost.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, especially to the technical field of oil gun mechanical devices for coal-fired thermal power station boilers starting and low-load stable combustion, and specifically relates to the ejection-type high-fog oil gun. Carburetor technical field. Background technique [0002] As far as the oil guns of coal-fired thermal power plant boilers are started and low-load stable combustion is used to burn diesel oil, due to structural reasons, conventional atomization methods are generally used, and there are problems such as unsatisfactory atomization effect of oil particles, coarse oil particles (50 -300μm), poor uniformity, poor flame stability, and low burnout rate, defects and disadvantages. Based on the inventor's professional knowledge and work experience and unremitting pursuit of the cause, on the basis of careful investigation, analysis, understanding, summary, and research on the existi...
