Abstract

The utility model relates to a steam generator, which relates to auxiliary equipment of petroleum production. The utility model is composed of a fuel atomization chamber, a combustion chamber, a gas and water mixing chamber and a mixture vaporizing chamber which are orderly connected through a nozzle. Steam temperature produced by the utility model is determined by the temperature of high-temperature air produced by the combustion chamber without the limitation of the saturation temperature of the steam, and the temperature can reach 2300K and can fully meet the requirement of petroleum production. The utility model can be directly arranged below an oil well to work, can effectively reduce the consumption of heat energy, can save the energy, can improve the heat efficiency, can reduce the cost, can reduce the ground workload and can improve the mobility in use because of no need of positioning for use.

Description

Steam generator

The utility model is a kind of steam generator, relates to the oil exploitation auxiliary equipment.

Oil for high density, high viscosity generally is to adopt boiler generation steam in ground again steam to be transported to the oil reservoir place by pipeline crude oil to be heated the technology of assisting exploitation at present, the saturation temperature of steam is 360 degree, adds steam heat loss in course of conveying and makes the heating weak effect greatly.In addition, owing to will boiler etc. be installed on ground, thereby cost height not only, its mobility is also relatively poor.Recovery ratio generally can only reach 25-30%.

The purpose of this utility model is: design a kind of steam generator that can improve recovery ratio.

The utility model is made up of the mixing chamber of the fuel atomization chamber, combustion chamber, gas and the water that connect by nozzle successively and the vaporizer of mixture.

The utility model utilizes liquid fuel to heat, and for realizing abundant burning, at first will utilize atomising mechanism with fuel atomization before its fuel.High-temperature gas through producing after air burns mixes with water in mixing chamber, forms steam by vaporizer again, and like this, the temperature of steam depends on the temperature of high temperature air, and is not subjected to the restriction of water vapour saturation temperature, and its temperature can reach 2300K.Thereby can fully satisfy the requirement of oil exploitation.In addition, the utility model can be placed directly into and carry out work under the oil well, reduces thermal losses effectively, thereby energy savings, improve its thermal efficiency, and can reduce cost, owing to needn't locate use, thereby can also reduce the ground handling amount, and improve the mobility of its use.

For ease of the utility model is put into oil well, preferably that each several part is in one line, reduce its radial dimension.

Its concrete structure can be: air intake, fuel inlet and water inlet are positioned at the upper end of shell, fuel inlet directly is connected with spray chamber, the water cavity that the pipeline that is connected with air intake passes between shell and spray chamber, combustion chamber, mixing chamber and the vaporizer is connected to spray chamber upper end, upper end, combustion chamber, mixing chamber upper end by intake valve respectively, and is connected with an inlet of the terminal nozzle of vaporizer; Water inlet water receiving chamber, water cavity is connected with mixing chamber by water intaking valve, and water cavity also is connected with an inlet of the nozzle of vaporizer end.

For improving the impulsive force of gas that the combustion chamber produces, combustion chamber of the present utility model is made up of the inside and outside three-decker that connects successively, has spirally-guided mechanism at least in one deck.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the cutaway view of the utility model embodiment;

Wherein, 1-air intake, 2-fuel inlet, 3-water inlet, 4-shell, 5-spray chamber, 6-nozzle, 7-air auxiliary valve, 8-combustion chamber, 9-nozzle, 10-water intaking valve, 11-mixing chamber, 12-nozzle, 13-vaporizer, 14-nozzle, 15,16, the 17-intake valve.

As shown in the figure, present embodiment comprises that the upper end has the shell 4 of air intake 1, fuel inlet 2 and water inlet 3, spray chamber 5, combustion chamber 8, mixing chamber 11 and vaporizer 13 are from top to bottom arranged in the shell 4 successively, connect by

nozzle

6,9,12 between them, there is nozzle 14 lower end of vaporizer 13.Fuel inlet 2 directly is connected to the upper end of spray chamber 5, and the pipeline that is connected with air intake 1 is connected to combustion chamber 8 and mixing chamber 11 tops by

intake valve

15,16,17, and it also is connected on the inlet of nozzle 14.Water inlet 3 is connected in the cavity between the housing of shell 4 and spray chamber 5, combustion chamber 8, mixing chamber 11 and vaporizer 13, and connects an inlet of mixing chamber 11 tops and nozzle 14 by water intaking valve.There is the three-decker that connects successively the combustion chamber 8 of present embodiment, has spiral guide slot on the surface of the wall between three layers.
