Description

technical field [0001] The invention relates to the field of light hydrocarbon gasification devices, in particular to a pipeline type light hydrocarbon gasification device. Background technique [0002] The light hydrocarbon gasification device is a device that gasifies light hydrocarbon light oil and mixes it with air in a certain proportion to form a mixed gas. The light hydrocarbon light oil used for gas production is mainly C5 (carbon five), C6 (carbon six) and C7 (carbon seven). At present, it is possible to change C5 (carbon five) from a liquid state to a gaseous state, and mix it with air to form a combustible gas for people to use, but it is difficult to make C6 (carbon six) and C7 (carbon seven) into gas, and the existing The gasification device has disadvantages such as poor safety, low heating efficiency, large equipment volume, high cost, small gas production, quantitative control of oil-gas mixing ratio, and unstable gas quality.

AI Technical Summary

Problems solved by technology

However, it also failed to solve the problems of low heating efficiency, large equipment volume, and small gas production. Its intelligent control system failed to achieve quantitative, fixed ratio mixing and automatic control of oil and air, and the quality of the gas produced was unstable.

[0006] There are four major problems in the above-mentioned prior art: (1) The design of the oil heating device is unreasonable

Among them, it is unsafe to use electric heating rods to heat; it is uneconomical to use water circulation system to heat

(2) Unstable gas quality

Due to the unstable temperature of natural air, air bubbling is used to vaporize and mix oil with it, and the produced gas is affected by air temperature changes, and its output and quality are extremely unstable

Especially in winter, the mixing of a large amount of cold air will reduce the heating effect and inhibit the gasification of oil

Therefore, not only cannot normal gas production, but also the raw material for gas production is limited to C5 with a lower boiling point, and light oils such as C6 and C7 cannot be made into gas

(3) The existing control technologies for the production of light hydrocarbon gas mixed with air cannot effectively control the mixing ratio of oil and air, fail to realize the quantitative supply of oil, and it is difficult to accurately measure and calculate the gas production, gas consumption and cost. Difficult to achieve energy saving goals

(4) The process is complicated and the equipment is huge

The equipment corresponding to this technological process that can be saved includes: reactor, air tank, oil storage tank, gas storage tank and gas distribution tank, etc. These equipment are large in size, high in cost and low in efficiency
