Description

Technical Field

[0001] This invention relates to the field of gas pressurization equipment technology, specifically to an industrial device that uses ionic liquid to pressurize gas. Background Technology

[0002] With the rapid development of the gas industry, especially in the field of energy conversion and storage, efficient and reliable pressurization technology has become particularly important. Ion liquid compressors, as a new type of compression device, have significant advantages such as high reliability and long maintenance cycle. However, in existing ion liquid compressors, the piston can only correspond to a single compression chamber. With the rapid development of the industry, there is a need for compressors to further reduce space occupation, improve integration, expand the single compression chamber, and reduce manufacturing costs in industrial applications. Summary of the Invention

[0003] The purpose of this invention is to address the issue that the piston of an existing ion liquid compressor can only correspond to a single compression chamber. This invention discloses a structure in which two independent compression chambers are provided on the upper and lower parts of the piston, respectively. The structure includes: a cylinder head assembly (10), a piston assembly (20), an ion liquid (300), a cylinder body (301), a connecting rod (302), a cylinder liner (303), an inlet / outlet water connector (304), and a base assembly (40).

[0004] In the improved design, the ionic liquid (300) exists simultaneously in two independent compression chambers. When the machine is stationary, the ionic liquid (300) is placed on the upper piston (202) and the lower piston (204) respectively. The vertical arrangement of the compressor ensures that the ionic liquid (300) effectively adheres to the piston rings under the action of gravity. The structure of the two independent compression chambers is characterized in that the piston assembly (20) reciprocates in the cylinder liner (303) and the guide sleeve (403). The upper and lower parts of the piston assembly (20) are... The side spaces are separate upper and lower compression chambers. Depending on the operating conditions, the cylinder liner (303) heat exchange is divided into liquid cooling and air cooling. In the liquid cooling type, the cylinder liner (303) and the cylinder block (301) are combined to form a closed water chamber. The coolant enters from the inlet and outlet water connectors (304) and exchanges heat with the cylinder liner (303). In the air cooling type, the cylinder liner (303) and the connecting rod (302) are combined. The outer surface of the cylinder liner (303) is in the air and exchanges heat with the air.

[0005] In the improved scheme, the upper compression chamber and the lower compression chamber are characterized in that the two compression chambers are divided by a piston assembly (20), which includes an upper piston (202) and a lower piston (204) and is equipped with piston rings, thereby effectively isolating the upper compression chamber and the lower compression chamber.

[0006] Advantages and positive effects of the present invention.

[0007] Reduced space occupation and lower manufacturing costs: The single cylinder structure of the present invention has two sets of compression chambers. Compared with the existing single cylinder structure with one set of compression chambers, it can reduce one set of cylinder devices and corresponding drive devices. Therefore, it not only reduces space occupation, but also saves the types of parts, thereby reducing manufacturing costs.

[0008] Easy to maintain: The cylinder head assembly (10) and the base assembly (40) are both independently installed structures. This split design structure helps to quickly disassemble and install, thereby shortening disassembly time and reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0015] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] As shown in Figures 1-2, the compression chamber is an important structure of the compressor. In this invention, both the air-cooled and liquid-cooled types use the same compression chamber and piston structure, with the only difference being the heat exchange method for the cylinder liner (303). The structure in Figure 2 is based on the structure in Figure 1, with the cylinder body (301) replaced by a connecting rod (302).

[0017] The liquid-cooled dual-compression chamber structure in Figure 1 consists of the following parts: cylinder head assembly (10), piston assembly (20), ion liquid (300), cylinder body (301), cylinder liner (303), inlet / outlet water connector (304), and base assembly (40). The assembly relationship between the parts is as follows: the cylinder liner (303) is a hollow cylindrical structure, made of high-nickel stainless steel as specified in GB50516, and has sealing grooves on the upper and lower outer walls; the cylinder liner (303) is embedded in the cylinder body (301), and the two parts are tightly assembled. The upper end is fastened by the cylinder head bolt (101) in the cylinder head assembly (10), and the lower end is fastened by the base fixing bolt (401) in the base assembly (40); the cylinder body (301) is made of gray iron HT300. The material has a hollow cylindrical casting structure; the inlet and outlet water connectors (304) are installed on both sides of the outer wall of the cylinder (301); the coolant enters from one side of the inlet and outlet water connectors (304) and flows out from the other side; the outer wall of the cylinder liner (303) is wrapped with coolant, which plays a role in heat exchange.

Ionic liquid (300) is pre-filled at the top of the upper and lower compression chambers. When the piston assembly (20) moves vertically upward, the volume of the upper compression chamber gradually decreases, and the gas inside is compressed and then enters the lower compression chamber through the external pipeline. At this time, the volume of the lower compression chamber gradually increases. When the piston assembly (20) moves vertically downward, the volume of the upper compression chamber gradually increases, and gas entering from the outside is drawn in. At this time, the volume of the lower compression chamber gradually decreases, and the gas inside is further compressed.
