Description

Device for safely discharging washing water of wet electric dust remover for converter gas

Technical Field

The utility model belongs to the technical field of steel plant converter coal gas secondary purification, in particular to a device for converter coal gas wet-type electrostatic precipitator washing water safety discharges. The washing water of the wet electric dust remover for converter gas is safely discharged and carbon monoxide in the washing water is removed.

Background

Converter gas is a byproduct gas in steelmaking smelting, and the gas contains a certain amount of dust and can be used by downstream users only when the gas is purified to meet the standard requirements. At present, wet-type electric dust collectors are additionally arranged behind gas cabinets in domestic iron and steel enterprises to further purify gas. A large amount of atomized water is sprayed in the wet electric dust collector to purify and remove dust from the coal gas. After the atomized water is used for purifying and treating the coal gas, the atomized water is converged into washing water and is discharged through a V-shaped water seal below the wet electric dust collector.

Because a certain amount of carbon monoxide is mixed in the washing water discharged from the V-shaped water seal of the gas electric dust remover, the carbon monoxide can be emitted to the periphery from the water discharge port of the V-shaped water seal, and great safety threat is caused to the health of nearby personnel. After the coal gas wet-type electric dust remover adopts the device, carbon monoxide mixed in washing water of the wet-type electric dust remover can be effectively discharged to a safe area, and the situation that personnel are poisoned by coal gas is avoided.

The water-saving device comprises a V-shaped water seal 1, a V-shaped water seal lower part drainage stop valve 2, a water storage tank 3, a coal gas diffusion pipeline 4, a water storage tank overflow water seal 5, a water storage tank drain pipe 6, a water storage tank drain pipe stop valve 7, a water seal device drain pipe 8, a water storage tank flushing water pipe 9 and a water storage tank flushing water pipe stop valve 10.

Detailed Description

Example 1

The following describes embodiments of the present invention with reference to the drawings.

The utility model discloses a V-arrangement water seal 1, V-arrangement water seal lower part drainage trip valve 2, storage water tank 3, coal gas diffuse pipeline 4, storage water tank overflow water seal 5, storage water tank drain pipe 6, storage water tank drain pipe trip valve 7, water seal arrangement drain pipe 8, storage water tank wash pipe 9, storage water tank wash pipe trip valve 10. The bottom of the V-shaped water seal 1 is provided with a V-shaped water seal lower part drainage cut-off valve 2; the water discharging end of the V-shaped water seal 1 is connected with a water storage tank 3; a gas diffusion pipeline 4 is arranged at the upper part of the water storage tank 3, a water storage tank flushing water pipe 9 is arranged at the upper part of the water storage tank 3, a water storage tank drain pipe 6 is arranged at the bottom of the water storage tank 3, and the lower part of the water storage tank 3 is connected with a water storage tank overflow water seal 5; a water storage tank drain pipe shut-off valve 7 is arranged on the water storage tank drain pipe 6; a water tank flushing water pipe cut-off valve 10 is arranged on the water tank flushing water pipe 9; the overflow water seal 5 of the water storage tank is not connected with the water discharge pipe 8 of the water seal device;
