Solar heat collection device for vanadium and titanium slag heat absorption layer of composite metal runner

Abstract

A solar heat collection device for a vanadium and titanium slag heat absorption layer of a composite metal runner is arranged on building roofs, common ground, solar orientation slopes and other underlying surfaces which can receive sun radiation. The solar heat collection device comprises a heat collection coil, a circulation inlet connection tube and a circulation outlet connection tube, wherein the heat collection coil comprises a metal tube body and an adsorbing coating which is coated on the surface; one end of the heat collection coil is communicated with the circulation inlet connection tube, and the other end of the heat collection coil is communicated with the circulation outlet connection tube; an exhaust valve, a stop valve and a heat meter are arranged on the circulation inlet connection tube; and a safety valve, a fluid replenishment valve, an expansion tank, a filter, a pipeline pump, a stop valve, a check valve and an exhaust valve are arranged on the circulation outlet connection tube. The solar heat collection device is assembled on the underlying surfaces which can receive sun radiation, is a complete set of solar heat collection device, is simple in design principle and has good engineering workability and good technical economy; and the solar heat collection device is convenient to install and maintain and can be used for integrate domestic hot water and heating engineering.

Description

technical field [0001] The invention relates to a solar heat collecting device, in particular to a solar heat collecting device combined with a metal flow channel and a heat absorbing layer of vanadium-titanium metal slag. Background technique [0002] In the heat utilization of solar energy, the key is to convert the sun's radiant energy into heat energy. Because the solar energy is relatively scattered, it must be concentrated, so the heat collector is a key part of various solar energy devices. A solar heat collector is a device that absorbs solar radiation and transfers the generated heat energy to a heat transfer medium. [0003] There are three types of traditional solar collectors, vacuum tube solar collectors, flat plate solar collectors and ceramic solar collectors: [0004] 1. The main material of the vacuum tube solar collector is borosilicate glass, which is fragile and inconvenient for transportation and maintenance. This kind of solar collector is divided int...
