Delivery pipe in solar heating system

Abstract

The invention provides a delivery pipe in a solar heating system, belongs to the technical field of machines, and solves the technical problem of great loss of the delivery pipe in an existing solar heating system. The delivery pipe in the solar heating system comprises an outer pipe and an inner pipe, wherein the inner pipe is arranged in the outer pipe; a gap is reserved between the inner pipe and the outer pipe; end covers are fixed on the end parts of the inner pipe and the outer pipe; a mounting hole is formed in the outer pipe; a valve is mounted in the mounting hole; a heat storage material is also arranged in the gap and is prepared from the following raw materials in percentage by weight: 30-35 percent of silicon oxide, 7-10 percent of aluminium oxide, 0.3-0.5 percent of ferric oxide, 0.5-0.9 percent of calcium oxide, 0.4-0.6 percent of magnesium oxide, 1-3 percent of potassium oxide, 1-3 percent of sodium oxide, 2-5 percent of zinc oxide, 4-7 percent of coal ash, 1-3 percent of blind hole perlite microbeads, 0.1-0.3 percent of hexa-hydrated magnesium chloride, 0.5-0.9 percent of sodium carboxymethylcellulose, 0.6-0.9 percent of carboxymethylcellulose, and the balance of water. The delivery pipe in the solar heating system has the advantages of effectively reducing the loss of energy and improving the delivery efficiency of the delivery pipe.

Description

technical field

[0001] The invention belongs to the technical field of machinery, and relates to a conveying pipe, in particular to a conveying pipe in a solar heating system. Background technique

[0002] The solar heating system generally includes heat collecting pipes and delivery pipes. The heat collecting pipes can collect solar energy to heat the air in the heat collecting pipes. The heated air is transported to each room through the delivery pipes to heat each room. Since there are many rooms in an enterprise, it is necessary to use a long delivery pipe; during the delivery process of the delivery pipe, heat will be lost, and the actual heat delivered to the room is less, resulting in a waste of energy. Contents of the invention

[0003] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a delivery pipe in a solar heating system, which has the characteristics of effectively reducing energy loss. [0...
