Multilayer spiral pipe solar steam generator

Abstract

The invention discloses a multilayer spiral pipe solar steam generator comprising a barrel body. An upper seal head and a lower seal head are arranged at the upper end and the lower end of the barrelbody correspondingly. A first straight pipe located on the edge and a second straight pipe located at the center are arranged in the barrel body. Multiple spiral pipes are arranged in the barrel bodyfrom top to bottom at equal intervals. Each spiral pipe is a spiral bent pipe on a plane. The outer end of each spiral pipe communicates with the first straight pipe. The inner end of each spiral pipecommunicates with the second straight pipe. Two fixing plates which are opposite vertically are arranged on one side of the inner wall of the barrel body. The first straight pipe is fixed between thetwo fixing plates. Multiple supporting blocks which are vertically distributed at equal intervals are arranged on the other side of the inner wall of the barrel body. One side of each spiral pipe islocated on the corresponding supporting block. A first steam-water separation plate is arranged between the barrel body and the upper seal head. The top end of the second straight pipe is connected with the first steam-water separation plate through a connection column. The multilayer spiral pipe solar steam generator is simple in structure, convenient to maintain and replace and low in cost, andmeanwhile the multilayer spiral pipe solar steam generator is high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a multi-layer spiral tube solar steam generator. Background technique [0002] As a new type of non-polluting energy, solar energy has broad prospects and has attracted more and more attention from governments. Solar thermal power occupies an increasingly important position in the proportion of energy due to its cleanliness and safety. Steam generators are the core of solar thermal power plants. The core component is known as the "heart". The existing steam generator adopts a single spiral coil structure, that is, the coil spirals from bottom to top, and the coil is an integrated structure, which has the following two problems 1. If the coil leaks, it cannot be repaired due to the small gap between the coils, resulting in the need to replace the entire coil, and the cost is high; 2. The heat exchange area of ​​the coil is insufficient, and the heat exchange efficie...

[0002] As a new type of non-polluting energy, solar energy has broad prospects and has attracted more and more attention from governments. Solar thermal power occupies an increasingly important position in the proportion of energy due to its cleanliness and safety. Steam generators are the core of solar thermal power plants. The core component is known as the "heart". The existing steam generator adopts a single spiral coil structure, that is, the coil spirals from bottom to top, and the coil is an integrated structure, which has the following two problems : 1. If the coil leaks, it cannot be repaired due to the small gap between the coils, resulting in the need to replace the entire coil, and the cost is high; 2. The heat exchange area of ​​the coil is insufficient, and the heat exchange efficiency is not high, which urgently needs to be improved
