Engine assistant device used for natural gas extraction technique

Abstract

The invention discloses an engine assistant device used for a natural gas extraction technique. The engine assistant device used for the natural gas extraction technique comprises a tank body, a liquid inlet pipe and a liquid outlet pipe, wherein a bent heat exchange pipe is arranged in the tank body; a plurality of spoilers are arranged on the heat exchange pipe; a plurality of separation plates are fixed on the inner wall of the tank body at equal intervals; through holes are formed in each separation plate; the heat exchange pipe penetrates through the through holes; sealing rings are arranged between the heat exchange pipes and the through holes; the space in the tank body is divided into a plurality of air cooling areas which communicate with one another by the separation plates; the side wall of the first air cooling area and the side wall of the last air cooling area are separately provided with an air inlet; and the tank body is provided with an air outlet. According to the engine assistant device, an air flowing path in the tank body is reasonably designed, and air inlet is realized by utilizing the two air inlets, so that resource of cooling liquid is saved, and exploitation cost is lowered; the problem of a traditional air cooler that low-temperature cooling liquid is heated by high-temperature air in the last half flowing path is also avoided; and the heat exchange efficiency is effectively improved.

Description

technical field [0001] The invention relates to a heating device, in particular to an engine auxiliary device for a natural gas extraction process. Background technique [0002] With the rapid development of science and technology, people gradually realize the usefulness of natural gas, and it is widely used in various fields, making natural gas an indispensable energy source in people's daily life. The increase in demand brings frequent extraction, but natural gas is a non-renewable resource. With the deepening of extraction, some gas wells have entered the stage of low-pressure extraction due to the sudden decrease in the total amount of natural gas. In order to still be able to extract natural gas in the low-pressure production stage, the power consumption requirements for the driving equipment for gas well collection, that is, the engine, are much higher than the normal power consumption value, which will cause the shaft of the engine to generate a large amount of heat a...
