Abstract
The utility model discloses a heat recovering steam generator which comprises a generator main body. A hot material high temperature inlet is arranged at the upper portion of the outer wall of the generator main body, a hot material low temperature outlet and a soft water inlet are respectively arranged at the lower portion of the outer wall of the generator main body, a steam outlet is arranged at the top of the generator main body, a central pipe is arranged in the center in the generator main body, and a plurality of heat transfer tubes are evenly distributed around the central pipe. Material can pass through the central pipe, soft water can flow through the heat transfer tubes around the central pipe, and water can be driven by soft water density difference generated by temperature difference between the central pipe and the heat transfer tubs around the central pipe to circulate in the heat transfer tubes. The heat recovering steam generator is simple in structure and reasonable in design, uses soft water density difference generated by temperature difference to drive internal circulation of water, accordingly improves heat transfer coefficients and finally improves heat transfer efficiency.
Description
Technical field
The utility model relates to a kind of steam generator, is specifically related to a kind of steam generator for heat recovery.
Background technology
The type of cooling of the prior art generally adopts cooling water to cool off, this type of cooling not only cool time long, and the cooling not thorough, waste energy, and can not carry out the recycling of heat, wasted heat greatly.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve deficiency of the prior art, to provide a kind of simple in structure, can effectively reclaiming the steam generator of heat.
Technical scheme: a kind of steam generator for heat recovery described in the utility model, comprise the generator body, described generator body outer wall top is provided with the import of thermal material high temperature, described generator body outer wall bottom is respectively equipped with the outlet of thermal material low temperature and soft water import, described generator bodies top is provided with steam (vapor) outlet, described generator body interior center is provided with central tube, is provided with several equally distributed heat exchanger tubes around the described central tube.
As optimization, also be provided with interface of the level gauge on the described generator body outer wall.
Operation principle of the present utility model is: hot high-temperature material passes through from central tube, pass through soft water in the heat exchanger tube on every side, utilize the soft water density contrast of central tube and heat exchanger tube internal cause temperature difference generation on every side, drive the circulation of water in heat exchanger tube, can carry out heat recovery like this and produce steam, can improve the coefficient of heat transfer again, finally improve heat exchange efficiency, fast the cooling down high-temperature material.
Beneficial effect: the utility model is simple in structure, and is reasonable in design, and the soft water density contrast that produces by temperature difference drives the interior circulation of water, thereby has improved the coefficient of heat transfer, has finally improved heat exchange efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of steam generator for heat recovery as shown in Figure 1, comprise generator body 1, generator body 1 outer wall top is provided with thermal material high temperature import 2, generator body 1 outer wall bottom is respectively equipped with the outlet 3 of thermal material low temperature and soft water import 4, generator body 1 top is provided with steam (vapor) outlet 5, generator body 1 inside center is provided with central tube 6, is provided with several equally distributed heat exchanger tubes 7 around the central tube 6, also is provided with interface of the level gauge 8 on generator body 1 outer wall.
The utility model can be with the cooling of elevated temperature heat material, and heating produces steam after the heat recovery, and central tube adopts the heat exchanger tube of Φ 273mm, and peripheral heat exchange tube diameter is Φ 32mm.The advantage of this way: the reason of the difference of the soft water density that the thick central tube of utilization and peripheral heat exchanger tube internal cause temperature difference produce, drive the circulation of water in heat exchanger tube, the raising heat transfer coefficient finally improves heat exchange efficiency.
