Abstract
The utility model provides an oil gun, which belongs to the firing technical field of the electronic spray gun of fuel oil equipment (such as a fuel oil boiler), comprising a spray head cover for spray combustion and an outer tube connected with the back end. The gun core of an atomized regulating mechanism is arranged in the spray head cover. An inner tube is arranged in the outer tube which is connected with a steam joint. The inner tube is connected with an oil joint. The two joints are respectively provided with an adjusting valve. The utility model can do atomizing burning for counterweight heavy bottoms, which can guarantee to save oil 10%; owing to the function of a sealing surface, the oil gun has no leakage phenomenon in work; the service life of the oil gun is long; atomized granularity is smaller than 30um; the turndown ratio is big; the oil gun eliminates nozzle fouling and coke phenomenon.
Description
Technical field: belonging to fuel oil equipment (as oil burning boiler) electronics spray gun firing technique field, is a kind of heavy oil kind spray gun structure specifically, and it can be to fuel such as flammable residual oil, heavy oil, tar, coal tar, oli oils, can realize that all the cold conditions electronics lights a fire automatically.
Technical background: the ignition when main shot fuel is applicable to the boiler starting, utilize saturated vapor or compressed air will weigh residual oil and atomize through the rifle core, the oil mist particles degree is dwindled as far as possible, even particle distribution, its Size Distribution index N＞2.The fuel-viscosity variation scope of application is not more than 8 °F.The Flow-rate adjustment amplitude reaches more than 1: 4.Sufficient combustion, not over-emitting black exhaust, not oil dripping.Flue dust blackness content reaches State Bureau of Environmental Protection's set quota in the combustion product.The design feature of this rifle is: adopt the gas control valve, make steam or air advance outer tube through the vapour joint and directly enter the rifle core, director valve enters interior pipe through oily joint simultaneously, enters rifle core oil vapour and enters in the nozzle cap and atomize.Steam pressure is controlled at 0.18Mpa, and oils pressure is controlled at 0.4～0.5Mpa.The requirement of oil gun oil spout igniting is very high, and it is excessive particle to occur under a lot of situations, and the oil dripping situation appears in skewness, and it is insufficient to burn, and has so just reduced the economy of operation.Influence environmental protection, this shows, select that cost saving, oil mist particles are little, the igniting of environment-friendly type, dependable performance, main shot fuel be with regard to particular importance.At above-mentioned working condition requirement, the utility model all improves structure and material on the basis of former oil gun, makes this oil gun have good working performance, and the inclined hole owing to the oil gun nozzle cap having been adopted reasonable angle makes vaporific differentiation reach optimum.Adopt the steam bubble atomizing theoretical simultaneously, oilhole and steam vent design are big slightly, add and have improved technology, thereby solved spray nozzle clogging, coking problem well.
The present oil gun that uses is owing to structure and material therefor is different, and the performance difference of product is very big, and subject matter is: easily leakage, heavy oil atomize and do not reach effect.It is short spray nozzle clogging, oil pipe coking, service life to occur, and defective such as waste energy.
Summary of the invention: the purpose of this utility model is to provide a kind of oil mist particles degree little, and even particle distribution is regulated than big, reduces expenses noncoking, the oil gun of long service life.
For reaching above-mentioned purpose, the technical scheme that is adopted is a kind of oil gun, comprises the oil jetting combustion nozzle cap, carry out the rifle core of oily steam fogization, send the interior pipe of oil, the outer outer tube of supplying gas of pipe in being enclosed within is put into the gas joint of gas and the oily joint of oil-feed and is formed on the outer tube wall.Its head front end inclined-plane of nozzle cap is provided with the five equilibrium inclined hole that makes vaporific spraying, and this inclined hole plays mist of oil and becomes swirl shape to occur.
Straight hole and side that above-mentioned rifle core front end is provided with atomizing are provided with inclined hole
Be provided with sealing gasket between above-mentioned rifle core rear end and the outer tube.
The gas joint of above-mentioned outer tube becomes vertical related with the oily joint of interior pipe by outer tube.
Compared with the prior art the utility model has obvious advantage, can realize that vapour and heavy oil reach the following particle degree of atomization of 30um.And the inclined hole of rifle core is designed to appropriate angle, reach best atomizing effect, and adopted the high-quality stainless steel material, under long-term spray pattern, it is quite slow to wash away cavitation speed, increases the service life, owing to improved project organization, obstruction and coking phenomenon have been eliminated simultaneously.
Description of drawings:
Fig. 1 is the section of structure of the utility model oil gun.
The specific embodiment:
Further describe concrete structure of the present utility model and characteristics below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises the nozzle cap 1 of oil jetting combustion and is installed in the rifle core 2 that is provided with inclined hole and straight hole in the nozzle cap.Rifle core rear end is provided with gasket seal 3.The nozzle cap rear end connects the outer tube 5 of admission, is provided with the interior pipe 4 of oil-feed in the outer tube, and outer tube outer wall is provided with vapour joint 6, and outer tube back-end connects oily joint 7 and forms.Nozzle cap 1 front end inclined-plane is provided with the five equilibrium inclined hole, makes to form vaporific spraying, and oily joint 6 is vertical related by 5 one-tenth of outer tubes with vapour joint 7.
The utility model is according to handling characteristics, adopts a plurality of inclined holes spray vapour, makes it to intersect uniform atomizing with heavy oil, and it is made up of oil circuit and vapour road, at first opens the blow down valve of fuel pipe, makes combustion pipeline connection steam, purging fuel oil shower nozzle.Shut-down purge valve and steam control valve then.Open steam valve, make the manometric feedback demonstration 0.18Mpa that returns of oil pipe line, steam pipe road Pressure gauge show value is 0.4～0.5Mpa.Owing to adopted flow control valve, regulating ratio is increased, can reach more than 1: 4.And be provided with the ignition switch, guaranteed safe handling.And oil temperature is kept within the specific limits by adjusting, prevented the generation of flame-out phenomenon.
