An elastic support load control device and control method for a water-gas separator

Abstract

The invention discloses an elastically supported load control device and a control method for a water-gas separator. An elastically supported load control device for a water-gas separator includes a gasifier and a water-gas separator. The gasifier is separated from the water-gas There is a direct connection pipeline between the gasifiers, the gasifier and the water-gas separator are connected through the direct connection pipeline, and a liquid level indicating alarm is provided on one side of the water-gas separator, and the liquid level indicating alarm The output end of the liquid level regulating valve is provided with a liquid level regulating valve, and the bypass of the liquid level regulating valve is provided with a remote regulating valve. The present invention makes the structure of the whole device simple by setting the direct connection pipeline, and connects the gasifier and the water-gas separator through the direct connection pipeline, which is easy to implement, simplifies the space arrangement, effectively avoids the abrasion problem of the elbow in the natural compensation mode, and is economical and safe .

Description

technical field [0001] The invention belongs to the technical field of pipeline arrangement and stress analysis, and in particular relates to an elastic support load control device and control method of a water gas separator. Background technique [0002] In the field of coal chemical industry, the water gas produced by the gasification furnace of the coal gasification device is used as raw material gas to manufacture various coal chemical products after being separated by gravity in the separator and washed by the gas scrubber to cool down and remove dust. However, water gas that has not been separated by gravity has a large water content and is a three-phase gas, liquid, and solid, which is highly abrasive and corrosive. If the natural compensation method is used for the connection pipeline between the gasifier and the water-gas separator, there will be problems : (1) Affected by the characteristics of large pipe diameter, high temperature and pressure, the pipeline layout...

AI Technical Summary

Problems solved by technology

However, water gas that has not been separated by gravity has a large water content and is a three-phase gas, liquid, and solid, which is highly abrasive and corrosive. If the natural compensation method is used for the connection pipeline between the gasifier and the water-gas separator, there will be problems : (1) Affected by the characteristics of large pipe diameter, high temperature and pressure, the layout space of the pipe is limited, and it is difficult to implement; (2) Affected by the characteristics of the medium, the local abrasion of the flexible elbow is serious, and there are potential safety hazards

[0003] However, due to the large change in the weight of the internal material during the operation of the water-gas separator, the elastic support for the water-gas separator cannot be stably supported, and the nozzle load of the direct-connected pipeline cannot be kept within a safe and reasonable range. Technical problems to be solved for safe operation of chemical plant
