Warming pressurized reactor

Abstract

The invention discloses a temperature-increasing and pressurizing reactor. According to the invention, a cavity is respectively, detachably and hermetically connected with an upper cover and a lower cover, so that the sealing performance in the cavity is guaranteed. The side wall of the cavity is composed of two layers, wherein the side wall of the inner layer is a metal layer, and the side wall of the outer layer is a cast aluminum heater layer. The lower cover is divided into two parts, wherein the upper part of the lower cover is a metal layer, and the lower part of the lower cover is a cast aluminum heater layer. The lower cover is connected with a heating rod. The heating rod is located in the cavity. A heating port is formed in the cast aluminum heater layer. The cast aluminum heaterlayer is heated through the heating port. A piston is located in the cavity, and is connected with the piston rod. The piston rod is hollow. The upper part of the heating rod is located in the pistonrod. The heating rod is heated through the cast aluminum heater layer of the lower cover, so that a sample in the cavity can be heated. The heating uniformity of the sample is ensured. The piston rodis matched with the piston, so that the mud sediment temperature and pressure coupling experiment can be carried out. The reactor provides the data support for further research on hydrogeology.

Description

technical field [0001] The invention relates to the technical fields of hydrogeology and sedimentology, in particular to a temperature-increasing and pressurizing reactor. Background technique [0002] At present, most of the devices designed for temperature-increasing and pressurizing reactions are mainly used for research and analysis of rock minerals and other types of samples. These devices usually adjust the size of the sample to reduce the error of the sample during the temperature-increasing process. For heterogeneous samples with high water content such as silt, cohesive soil, and sludge, in the process of pore water and sediment research during the process of increasing temperature and pressurization, a single heating method is usually used, which is convenient for heating. Fast, but easy to cause uneven heating inside the sludge, resulting in large errors in the reaction process. Contents of the invention [0003] In view of the above technical problems, embodim...
