Tubular heat exchanger achieving automatic inspection and repair

Abstract

The invention relates to a tubular heat exchanger achieving automatic inspection and repair. The tubular heat exchanger achieving automatic inspection and repair comprises a heat exchanging tube set,a heat exchanger shell and an automatic control header. The heat exchanging tube set is located in the heat exchanger shell, the automatic control header is located outside the heat exchanger shell, the heat exchanging tube set is connected with the automatic control header, the automatic control header is connected into a control system, the states of tube bundles in the tubular set can be remotely monitored, and the flow rate of a heat medium in each row of pipe bundles is controlled. According to the tubular heat exchanger achieving automatic inspection and repair, in the running process, the flow rate of each row of pipe bundles can be controlled, data can be recorded, and inspection is conducted regularly; and when the data exception occurs, inspection can be conducted through a preset logic control program to determine the broken tube row, automatic treatment is carried out, and therefore the leakage problem is found in first time and solved in time, a great number of manpower and material resources and time are saved, and the heat exchanger advantageously and stably runs for a long time.

Description

technical field [0001] The invention relates to the technical fields of heat exchange such as electric power, environmental protection, chemical industry, and energy, and in particular relates to a tubular heat exchanger for realizing automatic maintenance. Background technique [0002] The function of the heat exchanger is to exchange heat between different media so as to achieve the purpose of fully utilizing energy. It is widely used in the fields of electric power and environmental protection. The heat sources outside the tubes, such as flue gas and steam, exchange heat. In order to improve the heat exchange efficiency, make full use of the space, and increase the contact area, the heat exchange tubes need to be arranged in a concentrated manner. [0003] The main structural form of the current tubular heat exchanger is that the heat exchange tube bundles are densely arranged to form a heat exchange tube group. The tube group is located in the heat exchanger shell, conne...

Problems solved by technology

This patent can control the opening and closing of the entire heating surface, but it cannot control the single tube row

[0007] The structural form of the heat exchanger disclosed in the above-mentioned patent documents has the characteristics that the heat exchange tubes are assembled into a heat exchange tube group, densely arranged, and the space utilization rate is high. However, once the heat exchange tubes are corroded, worn, etc. It is necessary to shut down the tube group and wait for the repair to resume after shutdown. The maintainability and operation of the heat exchanger are weak, and it cannot fully meet the automation and intelligent requirements of the current heat exchanger operation, and the reliability of long-term operation cannot be guaranteed.
