The invention relates to heat exchange devices for heating of liquids and can be used in oil and gas and other industries for heating water in tanks, for example, to prevent its freezing at low temperatures of atmospheric air.
Known systems of electric water heating in vessels with placing a heating cables outside on the vessel wall [1, 2], or with the placement of the heating elements inside the tank directly into liquid [3]. Electric heating of large quantities of water in tanks in oil and gas projects often involves overcoming significant technical difficulties. The disadvantage of such systems is the high cost of electric heating.
Known devices in the form of a coil pipe, placed outside the [4] or in [5] the tank. The coil is circulating heater coolant - water or water vapor. Such devices can work only at presence of an external source of heating of the heat carrier - boiler house, heating network.
The closest to the technical nature of the present invention is a device consisting of a burner unit, placed in the tank of a U-shaped flame tube, chimney, the basis of which is located in immediate proximity to the burning block outside of the tank [6] is a prototype.
In the known device as the heating of the heat carrier used high-temperature combustion of gas or liquid fuel, which is economically more advantageous than the use of electricity for heating the liquid in the tank. The disadvantage of this device is the relatively low intensity of heat of combustion products in the flame tube that leads to the necessity to do it with a large surface area of heat transfer, and therefore long and bulky. The disadvantage is low thermal efficiency due to the high temperature of combustion products at the outlet of the stack.
The present invention is increasing the intensity of heat transfer products of combustion in the flame tube, reducing its size and metal consumption, and increasing thermal efficiency.
The problem is solved in that the device for heating the water in the tank, consisting of a burner unit, placed in the tank of a U-shaped flame tube, chimney, the basis of which is located in immediate proximity to the burning block outside of the tank, is inside the flame tube ring-vortex generators, installed adjacent to the tank cover, which houses burner unit and the base of the chimney, through the roof of the shelter is the tube that forms with outer surface of the wall of the chimney annular channel, on the sides of the heating pipe installed vertical plate with Windows in the lower part of flow of the water.
Unlike the known device availability of the rings-turbulizer inside the flame tube intensifies the heat of combustion products with the wall of the heating pipe, and this reduces its size and metal. The presence of a shelter and a pipe going through the roof of the shelter and forming with the wall of the chimney annular channel, provide when passing through this channel atmospheric air it is heated by the heat of exhaust flue fuel combustion products. Admitted to the shelter heated air is sent to the burner unit for combustion of fuel. This reduces the temperature of the leaving of products of combustion, reduced consumption of fuel consumed, are provided with the necessary thermal conditions in the shelter for work burner unit and means of control and automation. All this leads to improved thermal efficiency and reliability of the device. Installed on the sides of the heating pipe vertical plates with Windows in the lower part for the passage of fluid provides a stable liquid circulation throughout its volume in the vessel, including in the bottom layer with low temperature and high density. This further increases the efficiency of the device and eliminates the risk of ice formation on the bottom of the tank.
Thus, the distinctive features of the invention allows to solve the problem.
Comparative analysis of the proposed technical solution with the prototype shows that the claimed device complies with the criteria of the invention "novelty".
In the known devices [1-5] no distinctive features of the proposed devices. Consequently, it is possible to draw a conclusion on the compliance of the proposed technical solution to the criteria of the invention of "substantial differences".
Figure 1 shows a cross-section B-B in figure 2, figure 2 - section a-a in figure 1 and figure 3 - external element I in figure 2.
An apparatus for heating water in the tank consists of a U-shaped flame tube 1, at the entrance to which is installed the burner unit 2, and is adjacent to the exit flue 3. Base 4 chimney 3 and burner unit 2 is placed in the shelter 5. Through the roof 6 shelter 5 passes pipe 7. Between pipe 7 and the chimney 3 there is a ring channel 8. The flame tube 1 is a fluid-filled cavity of the tank 9, connected with flange connector 10 and is fixed in space using a frame design, based on the bottom of the tank 9 and consisting of horizontal jumper 11 and vertical pillars 12. With the set step along the length of the heating pipe 1 on the inner surface mounted ring-vortex generators 13. On the sides of the heating pipe 1 installed vertical plate 14 15 Windows in the lower part of flow of the water.
An apparatus for heating water in the tank is as follows.
When the burner unit 2, which includes the burner and fan, is in the process of fuel burning. The resulting high temperature combustion gases enter heating pipe 1 and moving in the direction to the chimney 3, give warmth through the wall of flame tube 1 the surrounding fluid that fills the cavity of the tank 9. Ring-vortex generators 13 intensify the process of heat exchange between the wall of flame tube 1 and flow of combustion products. This process is limiting, to a large extent defines the total process of heat transfer from combustion products to the water. Therefore, intensification of heat exchange of a stream of gases increases the heat transfer rate and, as a consequence, to the decrease of overall dimensions and metal consumption of the heating pipe. Hot fluid in the space between the vertical plates 14 has a lower density under the action of Archimedean force rises up, giving place to come through the window of 15 cold liquid from the bottom layer of high density. This creates two closed-circuit the natural circulation of fluid in the cavity of the tank with a common Central upward flow between the plates 14. The temperature of the liquid in the whole volume of the tank 9 aligned, no danger of hypothermia and freezing of the bottom layer.
Shelter 5 is made gastight. Therefore, suction fan burner unit 2 of atmospheric air passes through the ring channel 8, where it is heated. Thus it creates the necessary temperature conditions for work burner unit 2 and placed in the shelter 5 equipment used to control the operation of the device. The heat for heating of the atmospheric air in the ring channel 8 goes through the wall of the chimney 3 from the exhaust of combustion products.
We offer the device for heating of water in the tank has the following advantages:
- high temperature uniformity of the volume of the heated liquid;
- reduced size and metal due to the intensification of heat exchange products of combustion in the flame tube;
- increased reliability of burner block and control systems device, placed in the shelter and protected from atmospheric influences;
- high thermal efficiency due to the heat recovery of exhaust of combustion products.
