The method of generating heat and the heat source
The invention relates to a power system, and in particular to methods of converting mechanical energy of the pressure of the moving fluid into thermal energy, and can be used in heat supply systems of various spheres of the national economy (industry, agriculture, defence, transport and household objects). The objective of the method is receiving thermal energy from the mechanical, the obtained liquid from the pump motor, such as electric, in a fundamentally new way, eliminating complex processing liquid. In the method, including the circulation of liquid through the pump is produced at the output of the pump throttling of the fluid, and the pump inlet grazing pressure in it. Grazing pressure is produced due to connection input connection of the pump to atmospheric pressure. The heat source for implementing the method includes a pump drive circuit connecting the pump outlet to the entrance. At the output of the pump is installed the throttle, such as a washer. The pump inlet is communicated with the surge vessel to release any excess pressure. In the track can be mounted radiator or coil boiler for heating or water heating. 2 c. and 6 C.p. f-crystals, 2 Il.
Currently, the known device, which uses a method of converting mechanical energy of the pressure transfer liquid in heat, for example vortex heating system (patent RF №2089795, F 25 29/00, priority 29.12.93 published 10.09.97), which contains heat exchange tank, inside of which is installed vortex tube. To Solovay input attached the working body of the pump connected to the motor. At the inlet and outlet of the vortex tube mounted ejector. The working body of the pump when the motor is started sucks circulating fluid and pumps it through to allow entry into the chamber of the vortex tube. Also known patent No. 2177591 called "Heat". The heat generator comprises a cylindrical housing with a tangential nozzle input victomology clip, on the surface of which are sealed hole for the tangential nozzle input and output pipe. Known heating system (patent No. 2045715, F 25 29/00, priority 26.04.93), entitled "Heat source and a device for heating liquids. The heat source includes a housing with a cylindrical part. It is equipped with an accelerator of the fluid, is made in the form of a cyclone, the end face of which is connected to the cylindrical body portion. In the method of heating produce turbulence, acceleration, braking fluid, and thereby heats up the liquid in the vessel of thermogenerator. The method produces a heating fluid directly without heating elements. The method by which the heating takes place in these devices adopted for the prototype.
The disadvantage of these systems is the complexity of the design, which leads to unnecessary costs, they create noise, for example when implementing a heat generator according to patent No. 2045715, as noted in the article "Energy from nothing" in the magazine "the Inventor and rationalizer" No. 10, 2000, was observed whistling to fight which was introduced to additional devices. In the U.S. the firm Hydro Dynamics Company similar device called "singing trumpet". How paucinaste path which produces the acceleration of the liquid cyclone unit or using a special drum, then brake fluid. The characteristic of fluid circulation in a closed office" is common for prospective method.
The problem solved by the invention is to obtain thermal energy from the mechanical, the obtained liquid from the pump motor, such as electric, in a fundamentally new way exclusive complex processing liquid. This eliminates the complexity of design and reduced noise, and reduced cost of devices for heating. While retaining all the advantages of this heating: no item temperature which exceeds the temperature of the liquid, which ensures the safety to fire and fouling, etc., Appear additional benefits due to total absence of the boiler and capacity of thermogenerator as elements, in which there is local heating, which reduces the size and weight of the plants, more uniform heating of the fluid throughout the system, reduces the inertia of the heating system, easy temperature control, and so on
For this purpose, in the known method, including circolazione pump at the suction side of the liquid in the pump - grazing pressure. Proceeding from the fundamental laws of physics and private laws of thermodynamics can be concluded that the energy received by the pump from the engine, is spent on heating elements of the device, fluid, surrounding objects and air and so on, i.e. all the energy received by the pump, is spent on heating, and ultimately can be used for heating or other purposes. Thus, the objective of the method of heating is to download pump up the necessary power. In the known methods it is produced by turbulence, acceleration and deceleration of the fluid. However, this can be achieved by throttling with the subsequent release of the pressure at the suction side of the liquid in the pump. This allows a simple way to capture and release of hydraulic power from the pump drive in the form of heat only, because the proposed method is not performed work on external objects. Energy consumption by the pump is moving fluid and a pressure, both these quantities at the outlet of the pump by throttling get the maximum value for the load of the pump and the minimum after grazing pressure. Thus, the energy received by the fluid through die temperature. In the following cycles the liquid will again take place the throttling process and grazing pressure and temperature increment will increase. Therefore, after each cycle the temperature of the liquid will increase until, until you turn off the drive or until thermal balance, i.e. the amount of energy supplied from the drive and given the environment, will not be equal. Grazing pressure can be effected by communication with atmospheric pressure (both directly and through the movable partition) or communication with the sealed volume in which the pressure different from atmospheric.
The implementation of the method, consider the example of a heat source, containing the pump drive circuit connecting the pump outlet to the entrance. For the prototype will take the heat generator and a device for heating liquids (patent No. 2045715, F 25 29/00, priority 26.04.93).
In Fig.1 presents a diagram of a heat generator in the composition of the heating system, and Fig.2 - scheme of the generator with another execution of the expansion vessel. The actuator 1 is connected to the pump 2. Input 3 and output 4 of the pump is connected by interstate 5. Output 4 pump installed throttle 6. As the throttle can be set washer, valve, narrowing of ustroystva.esli the heat sink 10. If necessary, you can use thermogenerator for heating the liquid to a temperature above 100°With the expansion vessel 7 is provided with a second fitting 11. While the expansion vessel is connected in line gap 5. That will allow the liquid in the vessel to circulate during operation of the pump, and then heated, i.e., to serve as a heat accumulator. The expansion vessel can be equipped with a flexible wall (diaphragm) 12 to prevent evaporation of liquid from the system, and is airtight and is connected via a fitting 13 and valve 14 track 15.
Works heat in the heating system as follows. When enabled, the actuator 1, for example, an electric motor, which actuates the pump 2, the water from the outlet 4 of the pump is fed to the reactor 6 through which the output connection of the pump to create the necessary pressure for this pump type corresponds to a specific and power consumption of the drive. The energy corresponding to the power load of the pump, will eventually be converted into heat which will be used to heat all parts and components of the heat source, and in the presence of the heat sink and the ambient air, and so on, Pressure is created upstream of the throttle and priskos to atmospheric or specified value in an airtight container. On this cycle the adoption of the mechanical energy of the moving portion of water (determined by the number of circulating fluid in the system and converting it into heat ends. Water, losing excess pressure, is fed to the inlet of the pump. This cycle is repeated several times, resulting in heating the liquid in the system to the required temperature. Throughout the track after the water outlet of the throttling device is excessive loss of water pressure and thermal energy is released. Thus, by throttling the fluid at the outlet of the pump and bleed pressure at the inlet it is the generation of heat from the pump, received from the actuator. Hot water passing through the radiator 10, puts some heat warming the room. In the example of a heat generator in the composition of the heating system drain pressure produced by communicating with the atmosphere. The expansion vessel can be made airtight (Fig.2) then, connecting to highway 15 pneumonias, you can open the valve 14 and pumping or evacuated from the air, to change the pressure in the expansion vessel, and thereby the pressure to bleed. This will eliminate the effect of atmospheric pressure on the system, as well as producing the hydraulic efficiency, so part of the energy goes directly into the heat and using the same path circulates in the system. The efficiency of the entire system is determined by the efficiency of the engine. The pump power select on the basis of the required power for heating, and the drive power must be chosen with regard to its efficiency.
