The atomizing device disclosed by the invention is rational in structure, safe and reliable, long in service life, and good in atomization effect.

Description

technical field [0001] The invention relates to a composite heat carrier generator, in particular to an atomization device of the composite heat carrier generator, and belongs to the technical field of oil extraction equipment. Background technique [0002] Injecting saturated water vapor into the oil layer for thermal recovery of heavy oil is one of the methods commonly used in all countries in the world, and has achieved good oil recovery effect and economic benefits. [0003] Most of the original thermal extraction is to inject the high-temperature and high-pressure steam generated by the surface boiler into the downhole oil layer, but this thermal recovery method has many shortcomings, such as large heat loss, high equipment and production costs, low crude oil recovery efficiency, and large environmental pollution. The mobility of the whole set of equipment is poor, and it is difficult to adapt to the requirements of oil well distribution operations. In order to overcom...

Problems solved by technology

[0003] Most of the original thermal extraction is to inject the high-temperature and high-pressure steam generated by the surface boiler into the downhole oil layer, but this thermal recovery method has many shortcomings, such as large heat loss, high equipment and production costs, low crude oil recovery efficiency, and large environmental pollution. The mobility of the whole set of equipment is poor, and it is difficult to adapt to the requirements of oil well distribution operations

In order to overcome the above-mentioned shortcomings, the Chinese patent application number 200510022594.7 discloses a high-temperature and high-pressure combustion system of a subcritical composite heat carrier generator. Great progress has been made in energy saving, mobility, etc., but this system also has the following disadvantages: 1. The outer peripheral wall of the combustion chamber lining is directly in contact with the cooling water, so the temperature of the cooling water rises quickly. When the temperature of the heat carrier When the cooling water temperature is higher than 300 degrees, the cooling water temperature is too high to cause scaling and block the water nozzle, and the reliability of the atomization device is poor; 2. There is no mixing device in the vaporization chamber, and the combustion smoke and liquid water cannot be fully mixed, so the atomization effect is poor
