Abstract
The utility model relates to a high pressure steam generator water cooling braise combustion device of thick oil well gas exportation and comprises a shell 1, heat preservation material 2, a water cooling tube bundle 3, a mold wall 4, a hot wind channel 5, a reflection plane 6, a mixer 7, a cold wind channel 8, a dust collection hopper 9, a mixing room 10, a combustion room 11, an inlet 12 and an outlet 13. The utility model can be used for replacing crude oil or natural gas with braise as the fuel of the high pressure steam generator. The utility model can ignite the boiler fast, combust steadily and improve the combustion efficiency as well as preventing coking and improving the combustion rate of the braise to above 98 percents. The employment of the utility model can save oil extraction cost and can achieve the aim of improving economic efficiency and saving energy.
Description
Technical field:
The utility model relates to a kind of high pressure steam generator coal powder burner that heavy oil wells is annotated the vapour exploitation that is used for.
Background technology:
Heat extraction by steam injection is the main mode of viscous crude field exploitation.At present, it is fuel that the high pressure steam generator that is used for heavy oil steam injection recovery adopts crude oil or natural gas usually, like this, certainly will need to consume substantial oil or natural gas, both influence the output of crude oil, natural gas, caused the part energy loss again, be unfavorable for reducing the raising of cost for oil production and economic benefit.
Summary of the invention:
The purpose of this utility model is to provide a kind of coal dust of using instead to substitute crude oil or natural gas as high pressure steam generator fuel, thereby can reach the water-cooled coal powder burner of energy-conservation purpose.
The utility model is to realize like this.This kind device is made up of housing, insulation material, water-cooled tube bank, pattern wall, hot-flow flue, reflecting surface, blender, cold air duct, ash dropping hopper, mixing chamber, combustion chamber, water inlet, delivery port, the housing inner chamber is divided into the mixed mode wall and closes chamber and combustion chamber two parts, lining has insulation material around the inboard, combustion chamber, and being provided with the water-cooled tube bank, the bottom is provided with ash dropping hopper; Mixing chamber front side inwall is provided with reflecting surface, and blender is equipped with in the outside, and its outer end protrudes from the housing front side, and upper and lower is respectively equipped with hot-flow flue and the cold air duct that communicates with the combustion chamber; Housing rear side upper and lower part is provided with water inlet and the delivery port that is communicated with the water-cooled tube bank respectively.During work, with wind coal dust is sent in the blender, wind powder mixing back is mixed in mixing chamber and is heated, and adopts coal dust hot air type suspension technology, and coal dust mixes in mixing chamber under the high temperature air effect fully, enters the combustion chamber after lighting.Because the pattern wall construction is adopted in the combustion chamber, solved and hung burnt, coking problem.This burner can reach the wind powder in the course of the work, heat is relatively stable rationally, and deashing, ash disposal move normal, the automaticity height.
The utility model can be used for using instead coal dust and substitute crude oil or natural gas as high pressure steam generator fuel, and can make the boiler lighting-up rate fast, flameholding, and the thermal efficiency improves, and avoids coking and the burn-off rate of coal is brought up to more than 98%.Utilize this device can reduce cost for oil production, reach energy-conservation and purpose that increase economic efficiency.
Description of drawings:
Fig. 1 is the utility model general structure schematic diagram.Fig. 2 is its front view.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is described further:
As shown in the figure:
The utility model is made up of housing 1, insulation material 2, water-cooled tube bank 3, pattern wall 4, hot-flow flue 5, reflecting surface 6, blender 7, cold air duct 8, ash dropping hopper 9, mixing chamber 10, combustion chamber 11 and water inlet 12, delivery port 13, and its structure assembled relation is as follows: housing 1 inner chamber is divided into mixing chamber 10 and combustion chamber 11; Mixing chamber 10 front side inwalls are provided with reflecting surface 6, and blender 7 is equipped with in the outside, and its outer end protrudes from housing 1 front side, and upper and lower is respectively equipped with hot-flow flue 5 and the cold air duct 8 that communicates with combustion chamber 11; Combustion chamber 11 inboard linings have insulation material 2, and are provided with water-cooled tube bank 3 and pattern wall 4, and the bottom is provided with ash dropping hopper 9; Housing 1 rear side upper and lower part is provided with respectively and water-cooled tube bank 3 water inlets that are communicated with 12 and delivery port 13.Wherein, housing 1 is horizontal cylindrical shape generally, and material is Q235, and its underpart is provided with ash dropping hopper 9; Water-cooled tube bank 3 adopts the pattern wall technique to be made into the water-cooling circulating system that contains pattern wall 4.Hot-flow flue 5, mixing chamber 10 adopt 1GY18Ni9Ti; Make; Reflecting surface 6 adopts refractory brick to make, and plays the convection current reflex; It is bucket-shaped that blender 7 is spray, adopts the Q235 material to make, and is used for the wind powder and mixes.
