Integrated high-pressure gas supply system with solar Stirling generator unit

Abstract

The invention discloses an integrated high-pressure gas supply system with a solar Stirling generator unit. The integrated high-pressure gas supply system comprises at least one integrated gas supply system, a plurality of Stirling engines and a gas supply pipeline; each integrated gas supply system comprises a high-pressure gas storage tank and a low-pressure gas storage tank and is connected with each Stirling engine by the gas supply pipeline; the gas supply pipeline comprises a main gas supply channel, a main gas return channel and internal generator gas channels which are communicated with the two main gas channels; gas return channels are connected with the main gas return channel by gas return channel connectors, and gas return electromagnetic valves which are used for regulating flow rates of gas working media exhausted out of generator working chambers are arranged on the gas return channels. The integrated high-pressure gas supply system has the advantages that independent gas supply systems which are originally independently fixed onto a solar Stirling generator unit are integrated at the bottom the integrated high-pressure gas supply system, the integrated high-pressure gas supply system is good in maintainability and convenient to maintain, and aerial operation is omitted; owing to the integrated design, leakage points of an integral gas channel system are few, the quantity of components is low correspondingly, and gas leakage and fault probability is low.

Description

technical field [0001] The invention relates to an integrated high-pressure gas supply system, in particular to an integrated high-pressure gas supply system applied to a solar Stirling generator set. Background technique [0002] In the current field of Stirling photothermal equipment, relevant centralized gas supply system equipment has not been proposed or adopted. Each of these Stirling machines is equipped with separate high and low pressure gas cylinders, booster pumps and other equipment, resulting in high cost of the unit. There are many leakage points in the design, and it is very inconvenient to replace gas cylinders or replenish gas. [0003] In addition, there are centralized gas supply system products in some non-solar thermal power generation fields, but they are fundamentally different from the gas supply system adopted by Stirling solar thermal power generation equipment, mainly reflected in the nature of work, working conditions and control content huge dif...

AI Technical Summary

Problems solved by technology

[0006] 1. At present, similar products adopt independent gas supply system, and each unit is equipped with corresponding gas equipment, which leads to an increase in the cost of a single unit and a large workload for product assembly;

[0007] 2. The unit is bulky and heavy, which is not conducive to the design of the entire power generation system, and may cause the structural size of other equipment to become larger;

[0008] 3. Since the gas cylinder and the booster pump are placed on the engine, the height above the ground is at least 5 meters. Once the gas circuit fails, disassembly and maintenance are very inconvenient and dangerous
