Abstract
A safety device for a high-level overflow water system of cooling water of a gas cooler belongs to the technical field of converter flue gas purification and recovery. Comprises a cut-off valve, a blind plate, a U-shaped water seal and a liquid level measurer; the cut-off valve (1) is connected with the U-shaped water seal (3) through a flange, the cut-off valve (1) is connected with the blind plate (2) through a flange, and the liquid level measurer (4) is connected with the U-shaped water seal (3) through a flange. The cooling water is guided out from the outlet at the upper part of the cooler and then flows through the cut-off valve, the blind plate and the U-shaped water seal to be discharged.
Description
Technical Field
The utility model belongs to the technical field of converter gas cleaning retrieves, especially, provide a safety device for high-order overflow water system of gas cooler cooling water, water high-order overflow water system's method for high-order overflow water system's safety device.
Background
The main stream technology of the process for purifying and recovering converter gas in a steel plant adopts a dry dedusting process, before the converter gas meets the recovery condition and is sent into a gas tank, the process of fine dedusting and reducing the volume of the gas is carried out by a gas cooler, the gas cooler is the key for completing the process, a gas cooling medium adopts industrial water, and under the normal condition, cooling water is sprayed from the upper part of the cooler and is discharged from the lower part of the cooler. Considering the dangerous situation that the water outlet at the lower part of the cooler is blocked due to various reasons sometimes to cause that the cooling water cannot be discharged and rises, a high-level overflow water device is further arranged at the middle part of the cooler, and the rising cooling water is discharged through the overflow port when reaching the position of the overflow water port. The device is composed of a pipeline, the shape of the pipeline is V-shaped, the pipeline can be used as a water seal at ordinary times due to the fact that industrial water is filled in the pipeline when the device is in initial operation, gas in the gas cooler is sealed and does not leak, and when high-level water exists, redundant cooling water is led out of the cooler through the overflow device. When the device runs, the water leakage phenomenon occurs at the bottom of the U-shaped water seal pipe due to various reasons, and when all water in the U-shaped water seal pipe leaks out, the coal gas flows out along with the leakage point, so that the device is a serious coal gas leakage danger source.
Disclosure of Invention
An object of the utility model is to provide a safety device for high-order overflow water system of gas cooler cooling water has solved the U type water seal arrangement that high-order overflow water formed and has leaked the safety in production accident that probably takes place of the coal gas that appears owing to leaking inefficacy, has realized the normal production order of cooler continuous operation.
The utility model discloses a cut-off valve 1, blind plate 2, U type water seal 3, liquid level measurement ware 4, cut-off valve 1 adopts the flange hookup with U type water seal 3, and cut-off valve 1 adopts the flange hookup with blind plate 2, and liquid level measurement ware 4 adopts the flange hookup with U type water seal 3.
The cooling water is led out from an outlet at the upper part of the cooler, flows through a cut-off valve 1, a blind plate 2 and a U-shaped water seal 3 and is discharged. The cut-off valve 1 and the blind plate 2 are in an open state during production and operation, when an alarm signal of the liquid level measurer 4 appears, the cut-off valve 1 and the blind plate 2 are closed after manual confirmation, the pipe diameters of the cut-off valve 1 and the blind plate 2 and the U-shaped water seal 3 are the same, the flow speed of cooling water in the U-shaped water seal pipe is 1.5-2 m/s, the U-shaped water seal pipe is made of Q235-B, the wall thickness of the steel pipe is larger than or equal to 4.5mm, the measurement range of the water level measurer is 0-2 m, and when the measured liquid level.
The utility model has the advantages of, after adopting this device, appear leaking when U type water seal pipe, when the water level descends and reaches alarm value, the personnel on duty can in time handle, ensures entire system's safe operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention. Wherein, cut off valve 1, blind plate 2, U type water seal 3, liquid level caliber 4.
Detailed Description
The utility model discloses a cut-off valve 1, blind plate 2, U type water seal 3, liquid level measurement ware 4, cut-off valve 1 adopts the flange hookup with U type water seal 3, and cut-off valve 1 adopts the flange hookup with blind plate 2, and liquid level measurement ware 4 adopts the flange hookup with U type water seal 3.
As can be seen from the attached drawing, the cooling water is led out from the overflow outlet of the cooler, flows through the cut-off valve 1, the blind plate 2 and the U-shaped water seal 3 and is discharged; the pipe diameter of the cut-off valve 1, the pipe diameter of the blind plate 2 and the pipe diameter of the U-shaped water seal 3 are the same, the flow speed of cooling water in the U-shaped water seal pipe is 1.5-2 m/s, the material of a pipeline of the cut-off valve is Q235-B, the wall thickness of the steel pipe is more than or equal to 4.5mm, the water level measuring range is 0-2 m, when the measured liquid level is lower than 1000mm, an alarm is sent out, after confirmation of an operator, the cut-off valve 1 is closed, and when the U-shaped water seal pipe is to be overhauled.
