Description

Safety cover for pipeline transportation in chemical plants

technical field

The utility model relates to a safety cover suitable for pipeline transportation in chemical plants, which belongs to the technical field of pipeline transportation.

Background technique

In chemical production, many chemical raw materials will produce toxic gases during the preparation process. For example, the ore contains sulfur elements, and there will be gases containing sulfur elements during the extraction process. Usually, the gases containing sulfur elements are toxic gases, and many toxic gases are easily soluble. For water, it is difficult to separate the toxic gas at the source. Only the solution with toxic gas can be transported together through the pipeline. Since the pipeline needs to be connected in multiple sections to form a complete transportation channel, it is very difficult in the connection part. Leaks are prone to occur. Once leaked, toxic gas will accumulate around the connection part, which will easily affect the health of the staff.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figure 1, when the device is in use, the chemical pipeline is connected through the connecting end 5, instead of the mutual connection between the chemical pipelines in the prior art, and only the safety cover is used as a leaked container for detection. Such a structure can firstly reduce the wear of the end of the chemical pipeline, and secondly, once the end of the chemical pipeline is damaged or the safety cover itself wears out, it can be repaired by replacing the safety cover with a different size.

During installation, the connecting end 5 is sleeved on the chemical pipeline, and the anti-skid pad can further fix the safety cover on the chemical pipeline.

When in use, once a leak occurs, the detection device 3 will detect it and notify the staff in time. Since there is toxic gas in the connection chamber 2 at this time, after the chemical pipeline is closed, the leaked part needs to be poisoned through the exhaust port 9. The gas is extracted to ensure the safety of the staff.

A corresponding connecting cavity 2 is provided at the outlet of each connecting end 5, which can accumulate a small amount of leakage gas. When the gas content exceeds the standard, the detection device 3 will give an alarm, avoiding the occurrence of a small amount of leakage. If it is detected by the detection device 3 at this time, it is also possible to notify the staff to carry out maintenance, which is a waste of manpower. At the same time, an adsorption module 11 is arranged in the groove 12 on the inner wall of the connection end 5, which can absorb toxic gases. Many of the toxic gases are gases containing sulfur, and most of them are easily soluble in water. The adsorption module 11 performs a certain amount of absorption, until the adsorption module 11 is saturated, the toxic gas will leak into the connection chamber 2 and be detected by the detection device 3, thus prolonging the maintenance cycle and avoiding frequent maintenance. Reduced wear and tear on safety covers and pipes, improving durability.

The above description is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and deformations can also be made. And deformation should also be regarded as the protection scope of the present utility model.
