Abstract
The utility model relates to a heating tube whose heat-releasing area can be adjusted according to the change of the flue temperature. The heating tube includes an outside tubular container, and is characterized in that: a spacer is arranged on the middle upper part of the tubular container; a stop plate connecting a spring is arranged within certain limits above the spacer. The tubular container is filled with working medium. For the utility model of heating tube with adjustable heat-releasing area, the stop plate is separated from the spacer when the flue temperature is high, the working medium of the tubular container circulates in the heating pipe cavity after being evaporated, when the heating temperature is low, the stop closes on the spacer under the effect of the spring force. The working medium of the tubular container circulates in the container under the spacer. The utility model of the heating pipe cuts off part of the heat-releasing area when the temperature of the heating source drops, and thus the surface temperature of the heating pipe is higher than the wall temperature of the original heating pipe, which can solve the problem of acid corrosion on the surface of the heating pipe; Furthermore, the utility model is very practical due to the simple structure and low cost.
Description
Technical field
The utility model relates to a kind of heat pipe, relates in particular to a kind ofly to utilize the heat absorption of working media to evaporate a heat release condensation one backflow, and the adjustable heat pipe of heat release section of heat is transmitted in circulation " phase transformation ".
Background technology
At present, in industrial production, in order to save the energy, various flue gases all carry out waste heat recovery, and heat pipe is made into various waste-heat recoverers (heat-pipe air preheater, heat pipe waste heat boiler) and is widely applied in industrial production.During the work of heat pipe in the heat pipe waste-heat recoverer, the heat pipe surface temperature also descends thereupon and is lower than acid dew-point temperature in the flue gas when flue-gas temperature drops to uniform temperature, and formed acid forms corrosion with opposite heat tube in the flue gas.
Existing technology is Chinese disclosed heat pipe, do not corroded in order to make heat pipe, and can only with the loses heat cost, flue-gas temperature is improved.
Summary of the invention
Make heat pipe avoid the corrosion of acid dew point thereby the temperature that provides a kind of area by change heat pipe heat release section to improve the heat pipe surface is provided the purpose of this utility model, improve the service life of heat pipe.
The utility model is realized in the following way:
The adjustable heat pipe of a kind of heat release section comprises: one is positioned at the spacer ring of heat pipe heat release section shell container, and there is a baffle plate that is connected with spring a distance on spacer ring.
In the adjustable heat pipe of above-mentioned heat release section, when flue-gas temperature is high, the working media vaporization in the shell container, under the effect of steam pressure, plate washer separates with spacer ring, and steam moves to the heat release section of whole heat pipe, thereby heat release section is all worked.
When temperature was low, the steam pressure in the shell container descended, and baffle plate makes baffle plate and spacer ring closure under the effect of spring force, and steam can only be in the heat release section work below the baffle plate of closure.
The utility model has following effect:
1. the heat release section of utility model heat pipe is adjustable, thereby has improved the surface temperature of heat pipe, makes heat pipe have more antiacid corrosive power thus, has prolonged the service life of heat pipe.
2. the heat utilization efficiency height because this heat pipe wall temperature improves, can fall flue-gas temperature and end than original lower temperature, reclaims more heat, has improved the thermal efficiency of system.
3. the utility model is simple in structure, and it is low to make it cost; Manufacture craft is simple, and is therefore very practical.
Description of drawings
Fig. 1 is the structural representation of the adjustable heat pipe of heat release section that the utility model proposes:
Specific embodiments
Please refer to shown in Figure 1ly, the adjustable heat pipe of the utility model heat release section comprises, one is positioned at the shell container 1 in the outside, and support 2 is connected with the heat release section of shell container 1, and spring 3 is connected with support 2, plate washer 4 is connected with spring 3, has a spacer ring 5 to be connected with shell 1 in 4 times a distance of plate washer.Working media 6 is equipped with in shell container 1 bottom.
When flue-gas temperature was high, working media 6 vaporization separated at the effect lower baffle 4 and the spacer ring 5 of steam pressure, and the working media 6 after the vaporization is full of shell container 1.The steam pressure of shell container 1 descends when flue-gas temperature is low, baffle plate 4 under the effect of spring 3 with spacer ring 5 closures, the periodic duty in the shell vessel space of spacer ring below 5 of the working media 6 after the vaporization.
In sum, the adjustable heat pipe of the utility model heat release section can be widely used in can being made into all types of heat-pipe heat exchangers in the flue gas waste heat recovery apparatus of industries such as power plant, glass, cement.If obtain promoting and to produce good social efficiency and economic benefit.
