Transverse tube-type cooling tower with leakage testing and overhauling function and overhauling and leakage testing method

Abstract

A transverse tube-type cooling tower with a leakage testing and overhauling function comprises a cooling tower body, wherein a low-temperature water inlet tube and a low-temperature water outlet tube are respectively and correspondingly arranged on the cooling tower body, and a cooling water inlet short connector is arranged on the low-temperature water inlet tube, and is connected to a transparent rubber tube. The overhauling and leakage testing method provided by the invention is as follows: the free end of the transparent rubber tube is lifted to the position of a low-temperature water outlet of the lower-temperature water outlet tube, and water irrigation to the transparent rubber tube is performed; the low-temperature water inlet valve is opened so as to irrigate to a low-temperature water section; the low-temperature water inlet valve and the low-temperature water outlet valve are closed, and variation of liquid level inside the transparent rubber tube is observed; and when liquid level inside the transparent rubber tube is no longer changed, the leakage point position of a to-be-detected tube layer of the transverse tube-type cooling tower can be determined according to the liquid level inside the transparent rubber tube. The transverse tube-type cooling tower provided by the invention has a novel structural style, is convenient to operate and use, can effectively and accurately judge the positions of leakage points, and can be used for detecting without demounting a transverse tube wholly.

Description

technical field [0001] The invention belongs to the technical field of inspection and repair of a coal coking horizontal-tube cooling tower, and relates to a leak-testing and repairing device and a repairing and leak-testing method for a horizontal-tube cooling tower. Background technique [0002] The horizontal tube cooling tower is the most commonly used gas cooling equipment in the chemical production system. It is used to cool the coke oven gas to meet the temperature required for process production, and to cool the gas to meet the temperature required by the process. The cooling process is divided into primary cooling And finally cold. [0003] After the horizontal tube cooler has been in operation for a long time, its spray pipe is easy to corrode, and the corrosion problem of the equipment has improved after the transformation. After long-term operation, it was observed that there was a series of leaks in the cooling water pipe layer of the cooling tower. Because th...

Problems solved by technology

Because there are many layers of pipes, it is difficult to judge which layer of pipes is leaking, which brings difficulties to maintenance

If the horizontal tube cooler is directly inspected, in order to find the leak point, all the horizontal tubes need to be disassembled, which is time-consuming and laborious, and affects the stable operation of production
