Problems solved by technology

[0006] The disadvantage of the heat exchangers of the above patents is that although the heat medium pipes are designed to operate as a unit, once the heat exchange pipes leak, inspection and maintenance need to be performed after the equipment stops running, and only the heat medium pipes of the entire unit can be inspected. checking
It cannot be checked in time, and the heat exchange surface will be greatly affected after the unit is deactivated. Based on the above characteristics, according to the actual maintenance situation, it is necessary to design a heat exchanger that can be judged online, isolated online, and more convenient for maintenance.

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0023] Such as figure 1 , figure 2 As shown, a tube heat exchanger for easy maintenance. No. 1 is the heat exchanger shell, No. 2 is the heat medium pipe, and No. 3 is the heat medium control header.

[0024] In some preferred embodiments:

[0025] The heat medium pipe 2 is connected with the heat medium control header 3, the heat medium pipe 2 is installed inside the heat exchanger shell 1, and the heat medium control header 3 is outside. The shell 1 plays the role of protecting and supporti...

Abstract

The invention relates to a tube type heat exchanger which is convenient for maintenance, comprising a heat exchanger shell, a heat medium pipe and a heat medium control header. The heat medium pipes are combined in units, and the heat medium of each unit heat medium pipe can be precisely distributed and controlled through the heat medium control header. This patent proposes a tube-type heat exchanger that is convenient for maintenance. This heat exchanger can control the opening and closing of specific heat medium pipes during operation. The tank closes the specific heat medium pipe to ensure that the entire system can still operate normally without shutting down.

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 which is convenient for maintenance. Background technique [0002] In order to protect the environment, meet the requirements of national emission standards, and recycle and reuse heat to achieve the purpose of energy saving and environmental protection, tubular water-flue gas heat exchangers are widely used in the fields of thermal power generation and environmental protection chemical industry. The main form of this heat exchanger is heat exchanger Heat pipes, headers and external pipes are assembled to form a heat medium circulation system to exchange heat with flue gas. In order to make full use of the layout space and perform heat exchange efficiently, fins are often designed on the heat exchange pipes and arranged in a compact manner. The gap between the...
