Abstract
The invention discloses a steam generator used for heat recovery. The steam generator comprises a generator body, a hot material high-temperature inlet is arranged on the upper portion of the outer wall of the generator body, a hot material low-temperature outlet and a soft water inlet are arranged on the lower portion of the outer wall of the generator body, a steam outlet is arranged at the top of the generator body, a central pipe is arranged at the center inside the generator body, and a plurality of uniformly-distributed heat exchange pipes are arranged around the central pipe. A material passes through from the central pipe, soft water flows through from the heat exchange pipes around, and soft water density difference caused by temperature difference between the central pipe and the heat exchange pipes around is utilized to drive water circulating in the heat exchange pipes. The steam generator is simple in structure and reasonable in design, and internal circulating of water is driven through the soft water density difference caused by the temperature difference, so that heat exchange coefficient is increased, and heat exchange efficiency is improved finally.
Description
Technical field
The present invention relates to a kind of steam generator, be specifically related to a kind of steam generator for heat recovery.
Background technology
It is cooling that the type of cooling of the prior art generally adopts cooling water to carry out, this type of cooling not only cool time long, and cooling not thorough, waste energy, and can not carry out the recycling of heat, wasted greatly heat.
Summary of the invention
Goal of the invention: the object of the invention is in order to solve deficiency of the prior art, provide a kind of simple in structure, can effectively reclaim the steam generator of heat.
Technical scheme: a kind of steam generator for heat recovery of the present invention, comprise 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, and described central tube is provided with several equally distributed heat exchanger tubes around.
As optimization, on described generator body outer wall, be also provided with interface of the level gauge.
Operation principle of the present invention is: hot high-temperature material passes through from central tube, in heat exchanger tube, pass through soft water around, utilize the soft water density contrast of central tube and heat exchanger tube internal cause temperature difference generation around, drive the circulation of water in heat exchanger tube, can carry out like this heat recovery and produce steam, can improve again the coefficient of heat transfer, finally improve heat exchange efficiency, fast cooling down high-temperature material.
Beneficial effect: the present invention is simple in structure, reasonable in design, the soft water density contrast producing by temperature difference drives the interior circulation of water, thereby has improved the coefficient of heat transfer, has finally improved heat exchange efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
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, and central tube 6 is provided with several equally distributed heat exchanger tubes 7 around, on generator body 1 outer wall, is also provided with interface of the level gauge 8.
The present invention can be by cooling high temperature thermal material, and after heat recovery, heating produces steam, and central tube adopts the heat exchanger tube of Φ 273mm, and periphery heat exchange tube diameter is Φ 32mm.The advantage of this way: utilize the reason of the difference of the soft water density of thicker central tube and the generation of periphery heat exchanger tube internal cause temperature difference, drive the circulation of water in heat exchanger tube, improve heat transfer coefficient, finally improve heat exchange efficiency.
