Tester for heat transferring and pore flowing character of aqueuos porous media materials

Abstract

A test device consists of test box, water injection pipe, water supply box, solenoid valve, water heating box, water pump, gate valve, flow meter, water collecting box, water filtering box and thermocouple. It is featured as placing thermocouple and water injection pipe in test box packing full of multihole media, measuring water temperature in media and flow rate flowing through media pore for obtaining real time picture of heat transfer and flowing property of the media.

Description

technical field

[0001] The invention relates to a test device for the heat transfer and flow properties of porous media materials, in particular to a test device for the heat transfer properties and pore flow properties of water-containing porous media materials, and belongs to the technical field of geophysical and thermal parameter testing. Background technique

[0002] In order to study the thermal pollution of urban land subsidence and urban geology, it is necessary to test the heat transfer and flow properties of water-containing porous media materials. Among the existing technologies, the patent No. 94103302.3 is the invention patent of "Rapid Measurement Method for Weak Aquifer Permeability Coefficient". It is a technique for measuring the hydrogeology and permeability coefficient of weak aquifers; the invention patent of "Method and Device for Monitoring the Flow of Seawater to Freshwater Aquifers in Coastal Cities" with patent number 01806143.5 can only monitor the m...

Embodiment Construction

[0010] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the present invention includes: test box 1, water injection pipe 2, water supply tank 3, solenoid valve 4, heating water tank 5, water injection pump 6, D stop valve 7, heating device 8, A stop valve 9, B stop valve 10 , C shut-off valve 11, return pump 12, flow meter 13, water collection tank 14, filter screen 15, water inlet pipe 16, filter water tank 17, drain pipe 18, thermocouple element 19.

[0012] The test box body 1 is filled with the porous medium material to be tested, and multi-layer mesh thermocouple elements 19 are arranged in the material. One end of water inlet pipe 16 communicates with running water, and the other end stretches in the heating water tank 5, and is connected with float valve. A heating device 8 with temperature control is installed in the heating water tank 5 , and an out...
