Method and device for measuring anti-dirty performance of material surface based on weight method

Abstract

The present invention provides a measuring device for assessing the antisludging capability of the surface of the material, the measuring device mainly comprises an upper water tank, a lower water tank, an experiment box, a test desk, an upper water pipe, a lower water pipe, an overflow pipe, an overflow plate, an electric power, a temperature adjusting device, a working medium flow regulating device through the experiment box, a cycling pump and the like; the upper water tank and the lower water tank through the upper water pipe, and the upper water tank and the lower water tank through the lower water pipe and the experiment box respectively form a circulating system. When the working medium flows through the experiment box the sludge matter will deposit on the surface of the measured material test piece. When the test piece is detached and is dried by the constant-temperature electro-heating ventilating drying cabinet, the added weight of the test piece is weighted and the curve chart of the relationship between the added weight of the test piece and the time is drafted, and the antisludging capability is assessed by comparing the induction period of the dirt and the asymptotic value. The device can do assessing to one material or working medium, also can execute contrastive analysis to a plurality of materials and different working mediums, and has the advantages of high accuracy, good repeatability, quick evaluating, simple operation and the like.

Description

technical field [0001] The invention relates to a measuring device and method for dynamically simulating and comprehensively evaluating the antiscaling performance of a material surface, in particular to a testing method and a device used for evaluating the antiscaling performance of a heat exchange surface by detecting the weight of dirt deposited. Background technique [0002] Scaling on the heat exchange surface is an unavoidable problem. Due to the presence of dirt, the heat transfer performance of the heat exchange surface decreases, the flow resistance increases, and the equipment economy and safety are reduced. Therefore, it is particularly important to evaluate the scale inhibition performance of the heat exchange material surface. At present, the conventional weighing method for evaluating hot surface fouling monitoring is often limited by the surface manufacturing process of the material. For the evaluation of the scale inhibition performance of different materials...
