Liquid-cooling and gas-cooling air-diesel gas generators and application thereof

Abstract

The invention relates to liquid-cooling and gas-cooling air-diesel gas generators, and provides a liquid-cooling air-diesel gas generator, which aims to prevent an inner wall of a combustion chamber from being burnt out and eliminate the heat radiation loss of the combustion chamber and is used for combining thermal oil recovery with air injection and expanding the application of the thermal oil recovery and the air injection. An annular inclined-hole jetting unit and a short combustion chamber body which has a small combustion chamber diameter and is provided with coolant uplink and downlink straight groove channels are adopted, and softened water serving as a regenerative coolant is applied to the thermal oil recovery, so that hot gas flow, hot liquid flow and cold air can be alternately injected, and the application can be expanded by taking 25 to 50 percent hydrogen peroxide as the regenerative coolant. The invention also provides a gas-cooling air-diesel gas generator, and a five-strike jetting unit, an internal cooling air hole and an external cooling air uplink straight groove channel are adopted. The two air generators are provided with two jetting pipes and mainly applied to the thermal oil recovery and the thermal cleaning of wellhead ground oil stains, sea floating oil, beach oil stains and road surface ice and snow.

Description

technical field [0001] The invention relates to air diesel gas generator technology and application technologies such as thermal oil recovery, crude oil pollution removal, and road ice and snow removal. Background technique [0002] The book "Enhanced Oil Recovery Technology" edited by Jiang Jishui introduced thermal oil recovery technologies such as water steam injection and air injection to burn oil layers, and non-thermal oil recovery technologies such as water injection, air injection low-temperature oxidation, nitrogen injection, and carbon dioxide injection. Water steam injection is effective and can be produced industrially, but it needs to build a boiler steam station and a steam pipeline network, and the investment and heat loss are large. Injecting air to burn the oil layer is not easy to ignite and easily deflagrate, and the front edge of the fire line is difficult to control, so it has not been popularized and applied. Water injection is economical and effective...

Problems solved by technology

[0007] In view of the shortcomings of the existing technology of the air diesel gas generator that the inner wall of the combustion chamber cannot be burnt out and the heat dissipation loss of the combustion chamber cannot be effectively taken into account, and that it is only used for thermal oil recovery and not combined with air injection, in order to make the air diesel gas generator It does not burn out the inner wall of the combustion chamber, and has no heat dissipation loss in the combustion chamber. It can be used for thermal oil recovery and can be combined with air injection and expand its use to thermal removal of crude oil pollution and road ice and snow. The present invention provides a new type that belongs to a general inventive concept Liquid-cooled air diesel gas generator and an air-cooled air diesel gas generator
