Description

The invention relates to the production of building products, in particular for the thermal treatment of reinforced concrete products.

The aim of the invention is to improve the heat transfer efficiency of the installation.

Figure 1 shows a chamber cross sectional view in FIG. 2 — the same, section A-A in FIG.

The chamber consists of walls 1, forming a chamber 2 for placing reinforced concrete products 3. In the bottom part of the chamber there is a container 4 filled with heat storage material (TAM) 5 and separated by a horizontal partition 6 "In the volume of heat storage material 5 under the partition 6 there is a heat exchanger 7, The evaporation zone connected to the heat pipe 85 is in contact with the heat exchanger -7 heliocurture 9, and the condensation zone is in the bottom part of the tank 4 "A bubbler 10, a collector which is made with openings for the passage of coolant into chamber 2. Antifreeze is circulated in the heating system of the heat-accumulating material, heated in the receiver 11 of the solar circuit 9. Under the container 4 filled with heat-accumulating material 5, a thermos 12S is installed which is equipped with a reverse air a valve 139 located in its upper part. The chamber has a lid 14, a heating tank 15, a pump 16, a pipeline 17, which successively connects the sparger 10, the heating tank 15, the pump 16 and a thermos 12 to each other. n diffuser 189 located at the base of the bubbler 10, and has valves 19 and 200 V diff-

The fusor 18 is fitted with a jet 21, which is directed towards the bubbler 10 and, through a recirculation duct 22, is connected with the upper part of the chamber 2 o The solar contour 9 contains

1G solar energy receiver, pump 23 and pipe fittings 24 and 25,

The camera works as follows.

two modes: summer (April-Oct br) and winter (Oct br - March).

In the summer heating mode, the antifreeze water after the solar receiver 11 enters the heat exchanger 7, located in the volume of the accumulating accumulator 5, the heat exchanger 7 is connected to the heat pipes 8S while the heat pipe 89 is sealed at both ends, there is an easily evaporating working substance ( it is adjusted so that its boiling point is lower than the boiling point of the antifreeze circulating through the helium circuit 9). The working substance enclosed in the heat pipe 8- evaporates and moves as vapor into the condensation zones. at pipe 8, where heat is taken off with cold water into tank 4, as a result of which the steam condenses and, under the influence of gravity, flows into the xpar-bite zone of the heat pipe 80 Between the cho-1 us evaporation and condensation of the heat pipe 8 there is a horizontal partition 60 Thus, the heat pipe 8 can utilize the radiant energy of the sun. When there is no solar radiation (in the evening and at night) or it is not enough, the water is heated due to the accumulating properties of TAM, which accumulated enough heat during the thermostatic chamber operation. When the water temperature in the tank 4 reaches the required limits, open the valve 20, turn on the pump 16, which supplies heated water through the pipeline through the heating tank 15 to the pipeline, 17 and to the diffuser 18, where the cross section is much smaller, the water velocity increases, resulting in 21 Clair reduced pressure zone is formed, which continuously draws the heated air from the upper zone of the chamber 2.

The heat carrier flow and the trapped heated air are mixed and “-” are supplied to the bubbler 10 with openings, from which saturated with warm air water is poured into reservoir 4, where the air-mixed particles, which are lighter as water, are displaced by hydrostatic pressure of water and fill the chamber 2 in the form of supersaturated steam. Since there is a constant from 315

Soy air from the upper zone of chamber 2, the air-mixed air particles are continuously raised, and the heated water particles are in contact

with their product 3, giving them heat and airing them, and the heated air through the duct 22 is sucked into a zone of reduced pressure, where it is mixed with a turbulent flow of water. Some of the cooled water in the tank 4 is pumped by pump 16 to reheat into the heating tank 15.

After the end of the heat treatment, the substitute 16 is turned off, the gates close: kku 20 and the valve 9 is opened while the water from the tank 4 is discharged into the ter, my 12 days of preservation, the stretch; necessary for the next cycle. In the process of filling the ternos 2, the valve 13 is set to the position at which it releases air from the thermos 12, which ensures free discharge of water. Thermos 2a Then remove the cover 14, remove the finished products 3 from chamber 2, set In the chamber 2 a new batch of products and close the chamber with a lid 14S after which the valves 19 and 20a are opened. The valve 13 is set to position 9 in which the formation of a vacuum in the thermos is prevented from turning on the pump 16, and the process is repeated.

The construction of the chamber with a heat-storage unit 5 containing heat-accumulating material, a test device and heat pipes will make it possible to evenly apply heat to a large volume from the comparator.

As a result, the proposed coking of the chamber allows it to work around the clock using mixed water heating, without reducing the efficiency of the solar circuit. In addition, the practical application of the camera, which uses the original principle of transporting thermal energy; is an effective way to reduce the consumption of slnrpi.
