[0002] like Figure 2 As shown in the figure, the equipment connection diagram of the existing ultra-high pressure copolymer production device, these devices are prone to form wall-sticking materials inside some equipment and pipelines during long-term operation. When the wall-sticking materials become thicker and thicker, they will block the equipment and pipelines, seriously affecting the operation of the equipment and pipelines, and even cause safety hazards in the operation of the device. In order to solve the problem that the equipment and pipeline wall-sticking materials are becoming more and more serious during the long-term operation of the device, the device is often required to be stopped, and the equipment and pipelines are cleaned by a special cleaning equipment of an outsourced cleaning manufacturer to meet the requirements of the device operation. However, cleaning by an outsourced manufacturer has the following defects: (1): The maintenance time required for cleaning by an outsourced manufacturer is relatively long, about 7-8 days, which increases the overall maintenance time of the device; (2): The cleaning process of the outsourced manufacturer is complicated, and the tooling and prefabrication required, and the installation process takes a long time; (3): The cleaning process of the outsourced manufacturer is complicated and there are certain safety risks. For this purpose, an ultra-high pressure copolymer device and pipeline descaling system is provided. Utility Model Content

[0006] As a preferred technical solution of the utility model, the first equipment requiring descaling is connected to the return pipe through the second connecting pipe, and the second equipment requiring descaling is connected to the return pipe through the first connecting pipe.

[0007] As a preferred technical solution of the utility model, one end of the chemical washing liquid delivery pipeline is connected to a liquid inlet pipeline connected to one end of the third descaling device, and a valve is installed on the liquid inlet pipeline.

[0008] As a preferred technical solution of the present utility model, pressure sensors are installed at the liquid inlets of the first chemical washing liquid delivery pump and the second chemical washing liquid delivery pump, and the pressure sensors are electrically connected to the first chemical washing liquid delivery pump and the second chemical washing liquid delivery pump respectively through a controller.

During the shutdown and maintenance of the device, the pipelines of the descaling chemical cleaning system are connected to the equipment and pipelines that need to be cleaned, so that the system can form a loop, start the chemical cleaning liquid delivery pump, and at the same time, the equipment and pipelines that need to be cleaned are heated up to ensure temperature stability and ensure that the chemical cleaning liquid can always be in a circulating state. According to the filter pressure difference at the inlet of the chemical cleaning liquid delivery pump, the sticky wall material precipitated from the chemical cleaning liquid is cleaned out in time. When there is almost no sticky wall material precipitated in the filter, the chemical cleaning liquid in the equipment and pipeline can be returned to the chemical cleaning liquid storage tank through the return line, and the waste liquid can be loaded and processed through the unloading pipeline. The entire descaling process is short and efficient, which greatly reduces the descaling time of equipment and pipelines.

[0012] The system is equipped with two chemical cleaning liquid delivery pumps. When one chemical cleaning liquid delivery pump is blocked, the other chemical cleaning liquid delivery pump can start working, ensuring that the entire descaling system will not stop. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The equipment to be treated includes a first equipment 2 requiring descaling, a second equipment 3 requiring descaling and a third equipment 4 requiring descaling. The first equipment 2 requiring descaling, the second equipment 3 requiring descaling and the third equipment 4 requiring descaling are interconnected through pipelines. The equipment requiring descaling can be a combination of several equipments connected in series.

[0019] The first device to be descaled 2 is connected to the return pipe 9 via the second connecting pipe 10 , and the second device to be descaled 3 is connected to the return pipe 9 via the first connecting pipe 8 .

[0020] One end of the chemical washing liquid delivery pipeline 7 is connected to the liquid inlet pipeline 5 connected to one end of the third descaling equipment 4, and a valve 6 is installed on the liquid inlet pipeline 5.

[0021] Pressure sensors are installed at the liquid inlets of the first chemical washing liquid delivery pump 104 and the second chemical washing liquid delivery pump 108. The pressure sensors are electrically connected to the first chemical washing liquid delivery pump 104 and the second chemical washing liquid delivery pump 108 respectively through a controller, and can automatically detect whether the pump is blocked, thereby automatically switching to another pump to work, which can not only protect the pump from burning, but also ensure that the system can always work.
