Detailed Description
The present invention will be described in detail and specifically with reference to the following examples and drawings so as to provide a better understanding of the utility model, but the following examples do not limit the scope of the utility model.
As shown in fig. 1, the utility model provides a large-scale coil heat exchanger convenient to clean, which comprises a main body 1, wherein a round coil 2 is installed in the main body 1, one end of the round coil 2 extends out of the upper part of the main body 1 to form a medium inlet pipeline 3, and the other end of the round coil 2 extends out of the lower part of the main body 1 to form a medium outlet pipeline 4; a first branch pipe 5 is arranged on the medium inlet pipeline 3, and a second valve 15 is arranged on the first branch pipe 5; the medium outlet pipeline 4 is L-shaped, a horizontal section of the medium outlet pipeline is provided with a second branch pipe 6, and the second branch pipe 6 is provided with a first valve 7; the top of the main body 1 is provided with a feed liquid inlet 8 and a feed liquid outlet 9.
In the utility model, the circular coil pipe 2 is fixed inside the main body 1 through a fixing piece 10; the top of the main body 1 is also provided with a pressure measuring and controlling device 11; the lower part of the main body 1 is provided with a temperature measuring device 12; the bottom of the main body 1 is provided with a waste opening 13, and the bottom of the main body 1 is provided with supporting legs 14 at two sides of the waste opening 13.
The utility model relates to a large coil type heat exchanger convenient to clean.A medium inlet pipeline 3 is provided with a first branch pipe 5 for adding a cleaning agent and water, and a medium outlet pipeline 4 is provided with a second branch pipe 6 for discharging cleaned sewage. In normal operation of the heat exchanger, the first valve 7 and the second valve 15 are closed, i.e. the first branch 5 and the second branch 6 are closed. When the disc pipe of the heat exchanger needs to be cleaned due to a carbide thickening layer generated by high temperature after being used for a period of time, the heat exchanger is suspended to work, an oil medium in the disc pipe is discharged, the second valve 15 is opened, a cleaning agent and water are added and soaked for a certain time, then the first valve 7 is opened, and sewage is discharged from the second branch pipe 6; and then the first branch pipe 5 injects clean water to wash the glass, thereby finishing the cleaning operation.
While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
