Description

The invention relates to techniques for producing water, in particular to devices for producing water from atmospheric air.

The problem of obtaining clean water in the countries of the Middle East and North Africa to this day is an urgent, relevant and important. This is due to the climatic features of these regions, consisting in a hot climate, the lack of fresh water bodies.

The most common way to obtain water in the regions under consideration is the evaporation of sea water and the condensation of the generated vapor (distillation process). More economical is the method of producing water from atmospheric air when it is condensed on a chilled surface.

As the closest analogue, a device is adopted for receiving water from atmospheric air, comprising a channel for transporting a stream of atmospheric air, a cooling element located in a channel for transporting a stream of atmospheric air, and a condensate collection system (RF patent 2081256 C1, class E 03 B 3 / 28, publ. 06/10/1997, pp. 1-8). As a cooling element, a compression refrigeration machine or a thermoelectric module based on the Peltier phenomenon, the block of hot junctions of which are located at the outlet of the channel, can be used. Cooled dehydrated air blows around the block of hot junctions, lowering its temperature and increasing cooling capacity.

The disadvantage of this device is not fully used energy spent on condensation of moisture from the surrounding air. Using effects based on the mass difference of cold and warm air, you can increase the efficiency of the device, as well as abandon devices that direct the flow of atmospheric air (fans).

An object of the invention is to increase the efficiency of a device for producing water from atmospheric air. It is achieved through the use of a special device design, which also allows partial recovery of the consumed electrical energy.

In a device for receiving water from atmospheric air containing a channel for transporting a stream of atmospheric air, a cooling element located in a channel for transporting a stream of atmospheric air, and a condensate collection system, a channel for transporting a stream of atmospheric air is embedded in an outer case with a lower gap and channel formation between its lateral surface and the lateral surface of the cover for the withdrawal of dried air to the outside, in which radiators are installed to remove heat from the hot junctions thermoelectric their batteries, cold junctions brought into thermal contact with a cooling element located in the channel for transporting atmospheric air flow and consisting of a set of metal pins or tubes arranged in a checkerboard pattern, under which the turbine of the electric energy generator is located, to prevent condensed moisture from getting on the blades which is located above the last condensate collection system, which is an inclined grooves arranged in two layers in such a way that overlap in the cross section of the channel for transporting the flow of atmospheric air, but with a sufficient clearance for air to pass through them, and at the outlet of the channel for exhausting dried air there is a visor for discarding the drained air away from the entrance to the channel for transporting the flow of atmospheric air.

The design of a device for producing water from atmospheric air is shown in figure 1.

The device contains a cooling element 1 located in the channel 2, which, in turn, is embedded in the outer case 3. The cooling element is a set of metal pins or tubes staggered and cooled either by a compression type refrigeration machine or a thermoelectric module battery ( figure 1 indicates the battery of thermoelectric modules 4). Under the cooling element 1 in channel 2 there is a turbine 5 of an electric energy generator (the electric energy generator itself is not indicated in FIG. 1). To prevent condensed moisture from entering the turbine blades 5, the condensate collecting system 6 is located above the latter, which consists of inclined grooves arranged in two layers in such a way that they cover the entire cross section of channel 2, but with sufficient clearance to allow air to pass through them. Channel 2 is located in the outer case 3 in such a way that a gap 7 is formed from below, and a channel 8 is formed on the side between the walls of channel 2 and the outer case 3 to discharge the drained air to the outside. In the channel 8 there are radiators 9 that remove heat from the hot junctions of the thermoelectric modules 4. At the exit of the channel 8, a visor 10 is located, which rejects the drained air to the side of the entrance to the channel 2.

The principle of operation of the proposed device for producing water from atmospheric air is as follows. When the cooling element 1 is turned on, the air around the pins cools, as a result of which the moisture contained in the air condenses on the pins. Since the density of cold air is higher than warm, the cooled air "flows" from the cooling element and turns the turbines 5 of the electric energy generator. In place of cooled and already drained air, a new portion of the environment enters. Moisture condensed on the pins of the cooling element is collected in drops and drips down, falling into the grooves of the condensate collection system 6, after which it is discharged outside and used for its intended purpose. Cold air, passing through the turbine 5 and the gap 7, enters the channel 8, where the radiators 9 are located, which remove heat from the hot junctions of the cooling element 1. Here the air heats up and, as a result of a decrease in density, tends upward, further increasing the air draft in the moisture generator . As a result of this, the turbines 5 of the electric energy generator spin faster, and also the productivity of the device for receiving water from atmospheric air increases due to the acceleration of air flow. In addition, the removal of heat from hot junctions with cooled, dried air increases the efficiency of the cooling element 1. The peaks 10 throw the stream of warm, dried air to the side so that it does not fall back into the channel 2.

As already mentioned, both a compression-type chiller and a battery of thermoelectric modules can be used as a cooling element. When using a battery of thermoelectric modules, the device diagram looks like that shown in Figs. 1 and 2. If, however, a compression-type chiller is used, then pipes with cold refrigerant are discharged into channel 2, and pipes with hot refrigerant are discharged into channel 8.

Since there is no system for purification of the obtained water in the generator of moisture from atmospheric air, it can be used for technical purposes, in particular for agriculture. With appropriate treatment, the resulting water can also be used for drinking.
