Description

Technical Field

[0001] This application relates to the field of testing technologies, and particularly to a testing device for grey water scale inhibitor dispersants. Background Art

[0002] During scale inhibition performance testing, a certain amount of scaling cation and anion solutions are respectively prepared. After mixing the scale inhibitor dispersant with the cation solution, high-temperature pyrolysis pretreatment is first carried out, and then a spiral tube dynamic scale inhibitor tester is used to mix with the anion solution under set conditions to simulate the scaling process. The scale inhibition performance of the coal gasification grey water scale inhibitor dispersant is characterized by the scaling rate of the spiral test tube.

[0003] During the final measurement process, the spiral test tube needs to be weighed to obtain the scaling weight, and then the scaling rate is calculated. During this period, the spiral test tube needs to be disassembled before and after the test, the internal liquid is filtered, and it is separately dried and cooled before weighing. The whole process has many steps and is relatively complex, with a long interval time, which affects the test results and efficiency. Therefore, it is necessary to provide a testing device for grey water scale inhibitor dispersants to solve the problems raised in the above background art. Summary of the Invention

The cation solution is transported to the dispensing tank 12 for treatment, and is jointly transported to the metering pump group 13 with the anionic solution. Before that, the solution spiral preheating assembly 3 and the spiral test assembly 4 need to be flushed through the flushing tank 14, and dried through the heater 6, and the measured values of the measuring assembly 45 are recorded. After the cation solution is pretreated through the dispensing tank 12, it is transported to the spiral test assembly 4 together with the anionic solution through the metering pump group 13 and the solution spiral preheating assembly 3. During this period, the heater 6 is adjusted to the required temperature, and then the spiral test assembly 4 is adjusted to be inclined so that the solution in the spiral test tube 46 is discharged to the waste liquid treatment assembly 5 through the filter 47.
