Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment maintenance, in particular to a mobile skid-type cooling water replacement device. Background Art

[0002] In chemical production, due to the long-term efficient operation of production equipment, the pipelines that transport cooling water to the production equipment are prone to damage. External impurities mixed into the cooling water will cause the catalyst in the production equipment to become inactivated, affecting product quality.

[0003] At present, the solution generally adopted is to replace the pipeline. This solution faces problems such as cumbersome material returns and long maintenance cycle, which seriously affects work efficiency.

[0004] Therefore, it is necessary to study a solution that requires little modification to the original pipeline and takes a short time, so as to gain a certain buffer time for equipment inspection and maintenance, thereby avoiding shutdowns caused by equipment damage. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a mobile skid-type cooling water replacement device, comprising a skid frame (9), wherein a power controller (1), a desalted water tank (2), a pump (3) and a heat exchanger (4) are arranged in the skid frame (9), wherein the power controller (1) is connected to the pump (3) and the heat exchanger (4), wherein the bottom of the desalted water tank (2) is connected to the heat exchanger (4) through a water outlet pipe, wherein the pump (3) is arranged on the water outlet pipe between the desalted water tank (2) and the heat exchanger (4), wherein a desalted water return pipe (6) is arranged on the upper part of the desalted water tank (2), and wherein a desalted water supply pipe (5), a cooling water supply pipe (7) and a cooling water return pipe (8) are arranged on the heat exchanger (4).

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] 1. It can temporarily and quickly solve the problem of being unable to replace pipelines in a short period of time, ensuring efficient use of catalysts and reducing downtime losses;

[0008] 2. Using skids as carriers makes it easy to move and install in a small space, and has strong adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, they are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0025] In addition, if the descriptions of "first", "second", etc. are involved in the present utility model, they are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
