Description

TECHNICAL FIELD

[0002] The horizontal pipe primary cooler of the recovery workshop of the coking company is used for cooling the raw gas generated by the coke oven, and in the operation process, the gas passes through the shell pass, and the water passes through the pipe pass. Since the oil and ammonia water are contained in the condensed combined water in the raw gas, the corrosion of the ammonia water can cause the corrosion and damage of the horizontal pipe in the primary cooler. After the damage, a large amount of water enters the condensing system, which increases the load of the ammonia stripping tower, the steam consumption and the consumption of liquid alkali; at the same time, a large amount of raw water enters the residual ammonia water system, which can cause the scaling and blocking of the ammonia stripping raw water pipe, and the ammonia stripping treatment capacity becomes small; on the other hand, the cold water entering the tar system can form the oil-in-water phenomenon, which causes the difficulty in the dehydration of the tar in the oil depot, the increase of the steam consumption and the increase of the water content in the tar, thereby affecting the quality of the tar. When the horizontal pipe primary cooler leaks, it is difficult to determine whether it is the normal temperature cooling water pipe or the low temperature cooling water pipe, and a large amount of inspection work is required to check the two parts of the water pipe one by one, which is time-consuming and laborious and greatly affects the work efficiency.
