Method for simulating work environment for testing high-temperature stability of plastic filler and special device thereof

Abstract

The invention discloses a method for simulating a work environment for testing the high-temperature stability of plastic filler and a special device thereof, and provides a method capable of simulating the work environment for testing the high-temperature deformation amount of the plastic filler, which has the advantages of simple structure and use method, and a special device thereof. The invention solves the technical problems of large bed layer resistance, thermal-mass exchange effect reduction and the like directly caused by the fact that the detected deformation value of the plastic filler is not consistent with the actual value because only the thermal deformation value of a single plastic filler under no bearing can be detected in the prior art. The course of the method provided by the invention roughly comprises the following steps: firstly, filling an upright container with vertical walls with the plastic filler at a certain height, thereby maintaining the level surface of the plastic filler; then, selecting the special device, wherein the weight of the special device is the same as the weight of the bed layer borne by the plastic filler to be detected at the bottom of a tower after weighing; placing the special device in parallel on the surface of the plastic filler; simultaneously placing the special device, the bed layer and the plastic filler into a baking oven to be baked; and taking out the plastic filler after the baking to measure the deformation amount.

Description

[0001] technical field [0002] The invention relates to a method for testing plastic fillers in the fields of air separation and chemical industry, in particular to a method for testing the high-temperature stability of plastic fillers in a simulated working environment and a special device thereof. Background technique [0003] The structure of the packed tower bed in the field of air separation and chemical industry is generally: a supporting structure is set at the lower part of the bed, a grid cover is set at the upper part, and plastic packing is scattered in the middle, and the bed height is generally 3 to 10 meters. Among them, the role of random plastic packing is to provide an interface for heat and mass exchange between the descending liquid and the ascending gas. However, due to the thermal deformation of plastics at high temperatures, and the plastic packing under working conditions also bears the weight of the packing bed, the thermal deformation value is incre...

Problems solved by technology

[0005] The present invention mainly provides a method and a special device for testing the high-temperature deformation of plastic fillers with a simple structure and method of use, and can simulate the working environment. Lower thermal deformation value, so that the detected plastic packing deformation value is not consistent with the actual, which directly leads to technical problems such as large bed resistance and reduced heat and mass exchange effects.
