Description

Coal gas drainer with automatic water replenishing function

Technical Field

The utility model relates to a coal gas drainer technical field, more specifically the coal gas drainer with automatic water supply function that says so relates to.

Background

The gas system drainer is common in the metallurgical industry, and is simple in design, manufacture, maintenance and use, but in recent years, due to the rapid development of the application of gas in the metallurgical industry, the increase of the gas system drainers causes potential safety hazards and gas accidents in use and management to continuously appear, and the gas system drainer causes harm to the society.

The purification and dust removal of byproduct gas and cold gas of a generator in the metallurgical industry mostly adopt a wet dust removal process, so that the gas contains a large amount of water vapor and water mist. The dry dust removal also forms water vapor and water mist due to the water brought in by the metallurgical raw materials and the production process. The water vapor and the water mist are carried into the gas pipe network system by the gas flow, so that a large amount of condensed water is generated in the gas in the conveying process due to the reduction of the temperature and the change of the environment, and in addition, condensed mixtures of phenol, benzene, naphthalene, tar, hydrogen sulfide, cyanide, dust and the like in the gas are also deposited in the gas system, and the condensate can cause great harm to the gas system: the condensate will accelerate the chemical corrosion of the inner wall of the pipeline; the accumulation of condensate can increase the gas conveying resistance and reduce the flow; the surge is generated to cause the pressure fluctuation of the gas; when the gas is serious, water seal is accumulated at a low-lying position to cause interruption of gas transmission, even the pipeline is broken and collapsed due to overlarge bearing load, and malignant gas accidents are caused; therefore, the cold gas system must be provided with a drainer for draining condensed water, condensed mixture and part of deposited ash deposited in the gas system.

Because coal gas operating pressure is different, the effective height of design drainer water seal is also different, so the drainer can divide into low pressure drainer, high-pressure drainer and superhigh pressure drainer according to operating pressure, wherein:

the effective height of the water seal of the low-pressure drainer is lower than 1000 mm;

the effective height of the water seal of the high-pressure drainer is 1000-5000 mm;

the working pressure of the ultrahigh-pressure drainer is more than 50 KPa.

The drainer can be divided into the following parts according to the structural characteristics: horizontal drainer, vertical drainer, floater formula drainer, combination formula superhigh pressure drainer and plain type superhigh pressure drainer, wherein:

horizontal drainer: the automatic water draining device has the advantages of small volume, simple structure, low cylinder position, convenience in operation, inspection and maintenance and capability of continuously and automatically draining water, but once water is slightly deficient or the coal gas pressure overpressure pressure flees to blow out water stored in the water sealing chamber, coal gas is continuously leaked, the normal state is difficult to recover, and only water is replenished. Therefore, the horizontal drainer is suitable for being installed at a position with stable gas pressure and narrow place.

The vertical drainer: the gas-water seal device has the advantages of simple structure, convenience in operation and maintenance, large water seal chamber volume, more water, and water seal pressure channeling caused by gas overpressure or pressure fluctuation, and can generally seal gas to ensure the effectiveness of water seal after the pressure is recovered to be normal. The disadvantages are that the downcomer inserted in the water seal and the partition of the multi-stage drainer are prone to corrosion and perforation, resulting in a reduction in the effective height of the water seal, gas leakage, and difficulty in prior inspection and prevention.

A floating ball drainer: the working principle is that the buoyancy of water is utilized, when the floating ball floats along with the rising of the water level, the seal of the water outlet is opened, accumulated water in the water collecting tank is discharged through the gap of the floating ball sliding sleeve under the pressure of gas, the water level in the water collecting tank descends along with the discharging of water, the floating ball descends, the water outlet is sealed, the water discharging and the gas sealing are stopped, and when the water quantity is fixed, the position of the floating ball is stable and the discharged water is stable. The working pressure is generally 0.1-0.3 MPa. The automatic water draining device has the characteristics of small volume, simple structure, convenience in operation, inspection and maintenance, small influence by pressure fluctuation, difficulty in pressure channeling to cause a large amount of leaked gas, capability of realizing continuous automatic water draining, easiness in causing a small amount of gas leakage when the water quantity is small or a sealing surface is aged and damaged, and relatively high requirement on manufacturing technology precision.

Combined ultrahigh-pressure drainer: the working principle is that the ultrahigh pressure coal gas with water enters the pressure reducing tank through the downcomer and rapidly enters the low pressure coal gas system through a pressure reducing outlet valve connected with the low pressure coal gas system, so that the pressure of the coal gas in the pressure reducing tank is reduced, and the accumulated water in the pressure reducing tank is discharged through a high pressure drainer connected with a water outlet. It features that the pressure of used gas is generally below 0.15MPa, its volume is relatively large, its structure is relatively complex, and its installation place requires connection with low-pressure gas system.

Plain type superhigh pressure drainer: it is composed of inlet valve, drainage and pollution discharge valve, casing, hand hole and exhaust valve, and is generally designed into circular or round end socket to increase the compression strength. The working pressure is 0.1-2.5 MPa, the structure is simple, and the defect is that periodic drainage and pollution discharge are required.

In conclusion, the vertical drainer is selected for safety, reliability and economy, and 90% of the coal gas drainers in online operation are selected for the vertical drainers.

However, although the existing gas drainer has a mature structure, the water level of the drainer needs to be measured at variable times for water replenishment due to the evaporation of water. The main valve is closed during water replenishing, the exhaust water replenishing holes of all the chambers are opened for quantitative water replenishing, the labor intensity is high, and safety risks exist. And the pipe fittings are disassembled and plugged to cause abrasion, so that the risk of air leakage exists.

Therefore, how to provide an intelligent gas drainer capable of automatically replenishing water is a problem that needs to be solved urgently by technical personnel in the field.
