Technical field
The present invention relates to a kind of heat transfer of porous media material and the proving installation of flowing property, the proving installation of especially a kind of heat transfer character of moisture porous media material and flow of pore character belongs to geophysics and thermal technology's parameter technical field of measurement and test.
Background technology
In order to study the thermal pollution situation of urban ground subsidence and urban geology, the heat transfer and the flowing property that need the moisture porous media material of test, in the prior art, the patent No. is the patent of invention of 94103302.3 " quick detecting method for weak water-contained layer permeable coefficient ", is to the hydrogeology of aquitard and the determination techniques of infiltration coefficient; The patent No. is the patent of invention of 01806143.5 " method and apparatus that the monitoring seawater flows to the coastal cities fresh-water aquifer ", only can monitor the situation that seawater is shifted to the city.Two patented technologies all can not be finished the test of porous medium moisture back heat transfer character and flowing property.
Summary of the invention
In order to overcome the deficiencies in the prior art and defective, the invention provides a kind of proving installation, this proving installation can be tested the whole heat transfer character of moisture porous medium, and the flowing property of water in the hole.And under the influence of can sunykatuib analysis flowing, conduct heat at original porous medium, when geothermal reinjection, percolate such as recharge at situation, the Temperature Distribution of recharge water and mobility status.
The technical scheme that the present invention is adopted for its technical matters of solution is: in the test casing, porous media material to be tested has abrim wherein been buried a plurality of thermocouple elements in advance underground.Which floor the thermocouple element is divided into and constitutes a netted structure, can measure the temperature field in the whole box body space like this.Tap water enters heating water tank through the water inlet pipe of float control.Water in the heating water tank is by the heating arrangement heat temperature raising, the beginning of heating process and stop to be controlled by the temperature control loop in the heating arrangement.Be heated to the water of uniform temperature, enter feed-tank through solenoid valve.Switching according to the height of the water level in feed-tank control electromagnetic valve.Because heating water tank volumetric ratio feed-tank is many greatly, the feed-tank water outlet is relatively little, thereby can be so that the water temperature substantially constant in the feed-tank.Water in the feed-tank enters through six water pipes in the test casing that is full of porous media material, is back to header tank by six flowmeters respectively again.Water level in the header tank is predefined, and is lower than feed-tank water level, and guaranteeing has certain altitude poor with the feed-tank water level, regulates the flow velocity of testing water in the casing by the water level of regulating in the feed-tank.Overflow plate is arranged in the header tank, and the water of crossing overflow plate enters water tank with strainer by filter screen.
Test is pre-buried water injection pipe in the casing, can simulate and preset well, and water injection pipe is the stainless-steel tube that wall has some apertures.In test not to the water injection pipe water filling, the water that reaches design temperature enters the test casing, at this moment the temperature by the water in thermocouple and the flowmeter follow-on test porous media material and flow through the flow of medium pore water, and by special device continuous recording measurement data, draw the real-time graph of flowing heat transfer, with heat transfer and the flowing property that obtains moisture porous media material.
In test to the water injection pipe water filling, can simulate geothermal reinjection, percolate and situation such as recharge, by the measurement data of flowmeter and thermocouple, analyze under the influence that geothermal reinjection, percolate recharge the Temperature Distribution of water and mobility status in the porous media material.When changing the position of water injection pipe, flowmeter can record the mobility status apart from well different distance place.Water inlet in the water injection pipe comes from heating water tank, through the water pump pressurization, flows into through stop valve.When intake pressure does not need when very big, both the water of fixed temperature can directly not enter water injection pipe by water pump yet.When water injection pipe takes place to block, must take back the measure of raising in the injecting process.Return when raising, enter water tank with strainer by the water that returns in the lift pump extraction test casing.
This proving installation is simple in structure, can the simulate formation soil horizon in phreatic flowing and heat transfer characteristic, have substantial advantage and marked improvement.
