Description

Hot pipe heat-transferring system using waste heat under gravity

The utility model belongs to the improvement of civil heating system.

Existing Civil energy-saving cooking stove heating, hot water supply system, its heat transfer type mainly are to rely on the unidirectional gravity force of hot water to circulate to transmit heat.Because the amount of this internal system working medium is many, flow velocity slow, liquid unit's heat load is less, thereby heat transfer efficiency is low, fails to be popularized.So far the diffusing room residential building on the most of heating area of China, also main rely on the direct heating of stove or can not commercial heated kang, mode such as the warm heating of wall with flues cigarette.In recent years, because the development of hot pipe technique utilizes heat pipe to come heating and the existing application of hot water supply equipment.But because this equipment installation is grown, is difficult for the finished product production in factory, can only produce semi-finished product, install at home then, this just exists a problem how to make vacuum.Relevant heat pipe fills the introduction of working medium method in " heat pipe " textbook according to the nineteen eighty-three publication of scientific literature publishing house, and being used for making in the heat pipe vacuum method at present has four kinds, 1) Mechanical Method, 2) freezing scavenging, 3) bakeout degassing method, 4) the distilled water boiling method.Above-mentioned first three plant system vacuum method because will be by the multiple complex device of mechanical pump one class, general family is difficult for implementing; The 4th kind of system vacuum method is to utilize the distilled water boil in the pipe, utilize steam that original air is discharged but vacuum that it is made is lower, be not suitable for for the container on large tracts of land, multitube road.

Task of the present utility model provides a kind of adopting heat pipes for heat transfer system that can simply produce vacuum and the higher thermal utilization ratio is arranged.

Accompanying drawing 1 is the device schematic diagram of this system.(1) is thermal source, can is common Civil energy-saving cooking stove among the figure, (2) be heater, (3) be the location adjutage, (4) be fin, (5) be that water irrigating valve, (7) link contact for internal thread for vent valve, (6), can connect expansion tank (8) or pressure vacuum ga(u)ge (9), (20) can be general Domestic pot, kettle etc. for to use hot device.

Main points of the present utility model are: closable irrigation pipe be arranged at pipeline top, it is controlled by a water irrigating valve, has internal thread to link contact in the upper end of valve, is used for installing expansion tank or pressure vacuum ga(u)ge; Connect the location adjutage that can close at pipeline, its link position is lower than radiator, is higher than heater, and logical with the heater structure; Be provided with vent valve on radiator top.

When the heat control vacuum, 1. connect expansion tank earlier, open aeration valve and vent valve, pour into distilled water will manage in the former air of depositing drive out of, treat the vent valve water outlet after, close vent valve, and stop to pour water; 2. with thermal source heater is heated, the interior water conservancy project matter of heat pipe is heated produces the bulbs of pressure and then form the unidirectional gravity force circulation in pipe, the interior on-condensible gas that is contained of water conservancy project matter will be discharged from expansion tank through this process; 3. the cyclic process of water gravity continues after about 30 minutes, take off expansion tank, change pressure gauge, continue heater is heated, when the bulbs of pressure of water conservancy project matter in the heat pipe during greater than external atmosphere pressure, open the location adjutage, give off unnecessary water conservancy project matter, after locating adjutage effusion steam, close, close simultaneously irrigation pipe at once.

In order further to increase the work effect of heat transfer system, the utility model adopts a kind of heater that can make full use of the thermal source waste heat.

Accompanying drawing 2 is the profile of heater.

Accompanying drawing 3 is the sectional view of heater.

Heater in the utility model is by mild steel A₃Welded steel plate becomes hollow circular ring shape body. Its inboard heating surface (10) places around the thermal source flame, and heating surface is provided with some fins (18) to increase heating surface area; Be provided with gas outlet (11) on the outer rim top of heater and communicate with outlet pipe, the outer rim bottom is provided with water return outlet (12) and communicates with water return pipeline; Be provided with spiral flue (13), this flue that spirals of a circle in heater inside and advance mouth (15) and be arranged on the heater heating surface, outlet flue (16) is arranged on the heater outer rim, and links up with chimney; The flue bottom is provided with ash-falling hole (19); The space of heater inside except the flue that spirals places device of working medium, consists of water channel (14); A dividing plate (17) is welded on between mouth, gas outlet and outlet flue, the water return outlet, will advances mouth and outlet flue separates, also water return outlet and gas outlet are separated.

The inboard heating surface of this heater since not thermal source flame flow main aspect, thereby suffered radiant heat energy is lower, and the heat of the main aspect of thermal source is by with hot device absorption, its high-temperature flue gas enters the flue that spirals after with hot device bottom reflection; Because the setting of dividing plate, make the contrary that flows to of device of working medium in the trend of flue gas in flue stream and the water channel, so just further absorbing heat of heater, the flue gas of lowering the temperature is at last flowed out through chimney by outlet flue.

Compared with the prior art the utility model has UTILIZATION OF VESIDUAL HEAT IN efficient height, and heat pipe vacuum method processed is simple and feasible, is beneficial to the characteristics such as family's installation. Can be applicable to the aspects such as the heating of Civil energy-saving cooking stove heating installation, hot water supply, also can be applicable to the central heating aspect in small house zone.
