Overflow device of acetylene sludge slurry head tank

Abstract

The invention provides an overflow device of an acetylene sludge slurry head tank. The overflow device of the acetylene sludge slurry head tank comprises a sludge slurry head tank, wherein a top-open overflow groove is connected to the overflow port of the sludge slurry head tank, the other end of the overflow groove is connected to a collecting tank, and the cross section of the overflow tank is U-shaped or inverted trapezoidal; the overflow groove is inclined from top to bottom from the sludge slurry head tank to the collecting tank. The overflow device of the acetylene sludge slurry head tank is characterized in that the traditional overflow pipe is changed into the overflow tank, an open channel flow manner is adopted so that the volume of the overflow is clear and visual, the liquid level of the head tank is effectively stabilized and the liquid flooding phenomenon is completely avoided, and moreover, the overflow groove is convenient to clear so that the phenomenon of pipe blockage can be avoided and continuous stable operation of production can be realized.

Description

technical field [0001] The invention relates to the field of chemical production, and can be used for conveying pipelines easily blocked by sedimentation of slurry, in particular to an overflow device for a high level tank of calcium carbide slag slurry. Background technique [0002] Under the condition of the existence of the slurry high level tank (mainly composed of calcium hydroxide), it is easy to precipitate and scale. Generally, the liquid level gauge will be distorted after about two days of use, and the remote liquid level display cannot be accurately realized. The reason for this phenomenon is that the slag The overflow pipe installed at the overflow port of the slurry head tank, the slurry flow rate is slow, which is easy to cause the pipe to be blocked. The temperature of the slurry is 60-70°C, and there is a big safety hazard in unclogging, which increases the difficulty of the operation for workers. If the phenomenon of liquid overflow in the high level tank is...

[0002] Under the condition of the existence of the slurry high level tank (mainly composed of calcium hydroxide), it is easy to precipitate and scale. Generally, the liquid level gauge will be distorted after about two days of use, and the remote liquid level display cannot be accurately realized. The reason for this phenomenon is that the slag The overflow pipe installed at the overflow port of the slurry head tank, the flow rate of the slurry is slow, which is easy to cause the pipe to be blocked

The temperature of the slurry is 60-70°C, and there is a big safety hazard in cleaning the blockage, which increases the difficulty of the operation for the workers. If the phenomenon of liquid overflow in the high level tank is serious, it will affect the safety of production
