Example 2
The biggest difference between this embodiment and the above-mentioned embodiments is that the heat exchange outlet pipe 5 and the branch pipe 6 are welded, and the connection mode of this embodiment and the branch pipe is different.
A large amount of heat exchangers can be used in petrochemical production, and these heat exchangers adopt industrial water as heat transfer medium usually, nevertheless because reasons such as corruption, inside leakage can take place often for the heat exchanger, causes quality of water or product pollution, influences the heat transfer effect, can threaten the safe production operation even when serious, in time pinpoint the heat exchanger that leaks, and the safe operation of whole production is very important.
Consequently, the design concept of this scheme is exactly add monitoring mechanism on the heat transfer exit tube, makes the staff can be timely the observation to the coal gas of leakage, and then timely knows whether the heat exchanger leaks, then carries out work such as subsequent maintenance, guarantees the safe operation of production.
Under normal operating condition, circulating water pipeline is connected to the sight glass, is in full water state in the sight glass always, and when leaking in appearing like the inside core of cooler or little head, the gas side can be through the leak source entering water side pipeline in, the pipeline peak is risen to the bubble in the circulating water pipeline, is located the visual sight glass of high point, can clearly see the bubble condition, judges the leakage condition of cooler through bubble size and frequency. The utility model provides a leak detection device in coal gas cooler can be correct clear judgement cooler whether interior hourglass and interior hourglass state to can take temporary treatment measures under the unable equipment shutdown condition, guarantee equipment safe operation.
The working principle of the application is as follows: when the inside (gas pressure is greater than water pressure) of heat exchanger appears leaking, gaseous can get into in the water, utilizes the principle that gas is lighter than water, and the gas of final leakage can get into the glass tube sight glass on the pipeline of water side in, makes the staff in time know the inside leakage of heat exchanger.
In the normal operation state of the equipment, when no inner leakage occurs, the low-pressure medium (water) is filled in the glass tube sight glass; when internal leakage occurs, high-pressure medium (coal gas) enters the low-pressure medium side through an internal leakage point and enters the glass tube sight glass through a low-pressure pipeline (a heat exchange outlet tube); when the leakage amount of the high-pressure medium is small, a small amount of bubbles can appear in the glass tube sight glass and slowly rise to the top of the sight glass, and the sight glass is gradually filled; when the leakage amount of the high-pressure medium is large, a large amount of steam drums in the glass tube sight glass can rise, and the sight glass is filled quickly.
When the glass tube sight glass is actually used, when the glass tube sight glass is found to be filled with high-pressure medium for the first time, the bleeding valve is opened to completely bleed the high-pressure medium, and the amount of bubbles is observed again to judge the internal leakage amount; if the leakage amount is small and the safety production is not influenced, the bleeding valve can be properly opened normally to discharge the high-pressure medium at the bleeding valve to continue the operation of the equipment; the leakage amount is large, and the machine needs to be stopped for maintenance when the safety production is influenced.
The online detection device for the internal leakage of the heat exchanger can monitor the internal leakage condition of the heat exchanger on line at any time in the running state of equipment to ensure the heat exchange effect and safe running of the equipment, is simple and practical, and can be directly used as an equipment inspection point to monitor the running state of the heat exchanger, so that the reduction of the heat exchange effect in the internal leakage state and the high cost investment of equipment periodic inspection are avoided; this application design principle is reliable, and simple structure has very extensive application prospect, and what the heat exchanger of this scheme adopted is shell and tube type heat exchanger.
Although the present invention has been described in detail with reference to the drawings and preferred embodiments, the present invention is not limited thereto, and those skilled in the art can make various equivalent modifications or substitutions to the embodiments of the present invention without departing from the spirit and essential characteristics of the present invention, and these modifications or substitutions should be within the scope of the present invention/any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be defined by the appended claims.
