Vacuum tube type normal pressure heat collection and pressure-bearing operation integrated heat supply system

Abstract

The invention provides a vacuum tube type normal pressure heat collection and pressure-bearing operation integrated heat supply system. The vacuum tube type normal pressure heat collection and pressure-bearing operation integrated heat supply system comprises a heat preservation header and vacuum heat collecting tubes, wherein the inner ends of the vacuum heat collecting tubes are inserted into the heat preservation header; a heat exchange pressure-bearing guide pipe is arranged in the heat preservation header in a penetration manner; the heat preservation header is filled with heat conductionliquid; connecting end pipes communicating with the inner cavity of the heat preservation header are arranged at the two ends of the heat preservation header and are arranged outside the heat exchange pressure-bearing guide pipe in a sleeving manner; bidirectional reverse flowing pipe fittings are connected to the connecting end pipes; the heat exchange pressure-bearing guide pipe penetrates through the bidirectional reverse flowing pipe fittings; and the bidirectional reverse flowing pipe fittings are connected to air release valves or air inlet valves. The heat exchange pressure-bearing guide pipe is used for heating running water inside; the pressure of the pressure-bearing operation of the heat exchange pressure-bearing guide pipe is more than 10kg, so that the heat supply system candirectly communicate with pressure-bearing systems such as a municipal running water pipe network, a heat supply station heating pipe network, a ground source heat pump system and a boiler system. Theheat supply system has a simple structure and strong pressure-bearing capacity. The cost of the heat supply system is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar heating, and relates to a heating system integrated with heat collection and pressure operation of vacuum tube type and normal pressure. Background technique [0002] At present, solar collectors are mainly vacuum tube collectors. There are roughly three types of vacuum tube collectors in the market: the first type is single household type, the second type is combined engineering modules, and the third type is Heat pipe type. [0003] Analysis of the cost performance of the above three types of collectors: the first type is a single household type, which is cost-effective, and belongs to the normal pressure operation mode; the second type is a combined engineering module, which is cost-effective and belongs to the normal pressure operation mode, but due to the structure This determines its disadvantage of not being able to withstand pressure; the third type is the heat pipe type, which is low in co...
