Embodiment Construction
[0011] Further explanation is made below in conjunction with accompanying drawing:
[0012] The milk of lime stored in the milk of lime storage tank (1) enters the delivery pump (3) through the PTFE-lined pipeline (2) at the pump inlet, and the pressure on the PTFE-lined pipeline (4) at the pump outlet passes through the pressure transmitter (5) Send the signal back to the DCS control system cabinet (6), after being processed by the DCS control system, send the control adjustment signal to the electric frequency conversion controller (7), compare it with the preset program in the frequency converter, and control the delivery pump motor ( 8) operating current, so as to achieve the control of the outlet pressure of the delivery pump (3) to realize the delivery of milk of lime.

Description
technical field [0001] The invention relates to a method for conveying milk of lime. Background technique [0002] Lime milk is made by mixing quicklime and water, and usually contains 3% to 5% lime slag. In the prior art, in order to achieve the purpose of long-distance transportation of lime milk, carbon steel pipelines are usually used for high-pressure transportation. However, the smoothness of the pipe wall is poor, the frictional resistance is large, the head loss is large, and it is easy to block at the corners and low points of the pipeline. The perforation of the pipeline and the short service life of the pipeline. [0003] It is understood that there is no effective solution to the transportation of lime milk at home and abroad, and no relevant patented technology and reports in scientific and technological journals have been retrieved in this regard. Contents of the invention [0004] The invention provides a method for transporting milk of lime to relieve the...
