Problems solved by technology
[0003] Due to the high content of metal ions in the air, the value of metal ions in the pipeline is too high, which will easily cause secondary pollution of the equipment during the connection process between the equipment and the pipeline
If the traditional installation method is adopted (the method of first positioning the equipment and then installing the pipeline), although the adjustment amount is small and the construction difficulty is low, it is prone to greater pollution after the equipment is installed. When the pollution accumulates to the equipment, the cleaning and protection of the equipment will be required Brings several times the difficulty

Embodiment Construction
[0022] like Figure 1-4 Shown: a method for installing tank-type equipment in a factory building for preventing metal ion pollution, including the following steps:
[0023] 1. Confirm the center line of the tank equipment; since the center line of the fixed pipeline coincides with the center line of the tank equipment, before installing the pipeline and equipment, first determine the coordinates of the center point of the tank equipment with a total station. Operating standard: (1) When determining the center point position of the tank equipment, it should be based on the central axis of the plant control network. The measurement data is true and reliable. ⑵The measurement accuracy is within ±0.2mm to ensure the relative position when the equipment is connected to the pipeline and the position deviation when the flange is connected.
[0024] 2. Confirm the center line of the pipeline: take the center point of the equipment as the benchmark, and use a total station to measure...

An installation method for a tank type device in a metal ion pollution prevention plant includes the following steps that firstly, the center line of the tank type device is confirmed; secondly, the center lines of pipelines are confirmed; thirdly, data measurement is conducted, wherein a total station is erected at the position where the plant control network axis, the device circle center and fixed pipeline centers can be measured at the same time, the pipe opening center line of a device body and the center lines of the fixed pipelines are confirmed through the erected total station, and therefore the pipe opening center line of the device body and the center lines of the fixed pipelines can be on the same center line, and then data measurement is conducted; fourthly, the center lines of the fixed pipelines are adjusted; fifthly, recheck measurement is conducted; sixthly, the tank type device is hoisted to the installation position; and seventhly, after the tank type device is installed in place, connection of washed movable pipelines is conducted, and the whole pipelines and the device can form a system. By means of the installation method, cleanness of the device and the pipelines can be ensured, the metal ion pollution is effectively controlled, adjustment numerical values are small, the adjustment precision is high, and pollution cannot accumulate. Meanwhile, the installation method is high in construction speed and high in efficiency.
Description
Technical field: [0001] The invention belongs to the field of installation and maintenance of plant equipment for preventing metal ion pollution, in particular to a method for installing tank-type equipment in a plant for preventing metal ion pollution. Background technique: [0002] In the installation of anti-metal ion pollution plant equipment, the content of metal ions in the air directly affects the quality of the products produced, so the installation process of the equipment in the process of equipment installation and maintenance directly affects the cleanliness of the equipment. [0003] Due to the high content of metal ions in the air, the value of metal ions in the pipeline is too high, which will easily cause secondary pollution of the equipment during the connection process between the equipment and the pipeline. If the traditional installation method is adopted (the method of first positioning the equipment and then installing the pipeline), although the adjust...
