Abstract
The utility model discloses a vacuum hot water unit with a heat source, which belongs to a hot water-heating unit in a heating system. The vacuum hot water unit with the heat source comprises a heat source area and a vacuum heat exchange chamber positioned on the top of the heat source area, and is characterized in that: tube plates for fixing heat exchange tube bundles are mounted on both ends of the heat exchange area, the front tube plate is connected with a water outlet header and a water inlet header, and each heat exchange tube of the heat exchange tube bundles is a stainless steel tube or copper tube, on the inner and the outer walls of which a large-pitch helical convex-concave groove is formed by pressing and the outer wall surface of which is modified by adopting the plasma sputtering technology. The vacuum hot water unit has the advantages that: because the vacuum heat exchange chamber is adopted, negative-pressure operation is always kept in the heat exchange chamber during use, the heat efficiency can reach more than 92 percent because the high-efficiency heat exchange elements are adopted, and one to three sets of independent heat exchange tube bundles can be mounted in one unit and respectively used for supplying heating water, domestic water and water for swimming pools. The vacuum hot water unit is an energy-saving, emission-reducing and environment-friendly product.
Description
Technical field
The utility model belongs to the hot water firing equipment in the heating system, particularly has the hot water unit of thermal source.
Background technology
Usually the steam or the high-temperature water that generally adopt thermal source enterprise to provide in heating, hot water supply; Using heat transmission equipment to obtain with the hot junction; For the area that does not have the central heating condition or various boilers self-control steam of the general use of unit or hot water, but the general pressure-bearing of boiler has potential safety hazard, and the someone has developed combustion gas or fuel water heater group in recent years; Realized the operation of equipment normal pressure, but heat exchange efficiency is not high enough.
The utility model content
In order to overcome existing steam, the pressure operation of water bath furnace zone and the low deficiency of hot water unit heat exchange efficiency; The utility model provides a kind of vacuum hot water unit that carries thermal source; This carries the vacuum hot water unit of thermal source, and not only normal pressure is safe and reliable to operation; And can adopt the high efficient heat exchanging element, improved heat exchange efficiency, more energy savings.
The utility model solves the technical scheme that its technical problem adopted: a kind of vacuum hot water unit that carries thermal source; Comprise thermal source district and the vacuum heat exchanging chamber that is positioned at its top; It is characterized in that: the water inlet bobbin carriage that the tube sheet, the front end tube sheet that are used for fixing heat-exchanging tube bundle are connecting the delivery port bobbin carriage that has circulating water outlet and having the recirculated water inlet is equipped with at described heat transfer zone two ends; Vacuum heat exchanging chamber housing is provided with medium inlet and bleeding point, and the heat exchanger tube of described heat-exchanging tube bundle is to be squeezed into screw with long screw pitch emboss pit and outer wall surface on the inside and outside wall to adopt the plasma sputtering technology to carry out the stainless steel tube or the copper pipe of surface modification.
Be provided with the 0-2 road longitudinal divider vertical in the described terminal bobbin carriage with tube sheet.
Be provided with 1-3 group heat-exchanging tube bundle in the described heat exchanging chamber.
Combustion gas firing equipment, apparatus for fuel heating or electric heating equipment are equipped with in described thermal source district.
The operation principle of the utility model is: the boiling temperature of water water in the closed environment of lower pressure decreases; Water is continued heating heat the water in heat-exchanging tube bundle near 95 ℃ with it because the rising of the pressure following temperature of the continuous boiling closed environment of water increases the temperature of the steam that produces during near 700mmHg when pressure; Thereby form the pressure that condensed water has reduced closed environment after the steam heat release; Closed environment is to remain under the negative pressure in the vacuum heat exchanging chamber of the utility model to move in the reciprocation cycle process of heating, evaporation, heat release, condensation, and the heat exchanger tube that the heat-exchanging tube bundle of the utility model uses adopts the plasma sputtering technology to carry out the stainless steel tube or the copper pipe of surface modification as being squeezed into screw with long screw pitch emboss pit and outer wall surface on the inside and outside wall.This modification heat exchanger tube of experiment proof can make steam in the lasting formation dropwise condensation of heat exchanger tube outer wall; The heat exchanger tube outer wall surface is except that the part that the liquid pearl is occupied, and all the other expose in steam, and heat exchange is between steam and liquid bead surface and steam and exposed outer wall, to carry out; Because the liquid bead surface is long-pending more much bigger than its area occupied; No liquid film forms thermal resistance on the exposed outer wall, Gu the pearl heat exchange has very high heat transfer coefficient, actual measurement shows that the coefficient of heat transfer can reach 4900W/mm
2More than ℃; Can improve more than 2 times than common film condensation; The heat exchange tube wall is squeezed into the screw with long screw pitch emboss pit in addition, can make the flow regime of the recirculated water in the pipe become disorderly shape and then further improve heat exchange efficiency, can reach more than 92% according to the thermal efficiency of testing the utility model.
The beneficial effect of the utility model is owing to adopt the vacuum heat exchanging chamber; In use remain pressure in the heat exchanging chamber less than atmospheric pressure; Keep the negative pressure operation, adopted the high efficient heat exchanging element thermal efficiency can reach more than 92%, carry fuel oil, combustion gas or electrical heating thermal source; Use in the area that is specially adapted to not have the central heating condition, and equipment can be installed 1-3 and overlap independently that heat-exchanging tube bundle can be used to provide heating water, domestic water, swimming pool water respectively.The utility model be energy-saving and emission-reduction be beneficial to environmental protection product.
