Abstract

The utility model discloses a high purity and high pressure hydrogen reciprocating compressor. The high purity and high pressure hydrogen reciprocating compressor comprises a first section, a second section, a third section and a fourth section. The high purity and high pressure hydrogen reciprocating compressor further comprises a pipeline which connects the outlet of the first section and the inlet of the first section. Two ends of the pipeline which connects the outlet of the first section and the inlet of the first section are respectively connected with the inlet of the first section and the outlet of the first section. The inner diameter of a cylinder sleeve of the fourth section is 120mm. The number of the groups of piston rings is 14. During working time, when hydrogen comes out from the outlet of the first section, a part of the hydrogen returns to the inlet of the first section through the pipeline which connects the outlet of the first section and the inlet of the first section, and therefore the pressure of the second section is reduced. Due to the fact that the inner diameter of the cylinder sleeve of the fourth section is enlarged and the number of the piston rings is increased, the pressure of the third section is correspondingly reduced. Therefore, the overpressure phenomenon of a second section and a third section in the prior art is avoided.

Description

A kind of high-purity high pressure hydrogen reciprocal compressor

Technical field

The utility model belongs to technical field of chemical, is specifically related to a kind of high-purity high pressure hydrogen reciprocal compressor.

Background technique

Existing high-purity high pressure hydrogen reciprocal compressor generally comprises one section, two sections, three sections and four sections, can be used for forming the device of producing BDO.Four sections cylinder sleeve internal diameters of present employed high-purity high pressure hydrogen reciprocal compressor are 110mm, piston ring is 12 groups, be 99.8%(vol. in hydrogen purity), pressure is under the condition of 150 ℃ of 30.4Mpa, temperature, two, three sections superpressure phenomenons can occur in the using process, affect the normal production of device.

Summary of the invention

The purpose of this utility model provides a kind of high-purity high pressure hydrogen reciprocal compressor, has solved two, three sections superpressure phenomenons that existing high-purity high pressure hydrogen reciprocal compressor exists.

The technological scheme that the utility model adopts is: high-purity high pressure hydrogen reciprocal compressor comprises one section, two sections, and three sections and four sections, also comprise a pipeline one time, described pipeline two ends connect respectively described one section entrance and one section outlet.

Described four sections cylinder sleeve internal diameters are 120mm, and piston ring is 14 groups.

The beneficial effects of the utility model are that the utility model is set up a pipeline and is connected in one section entrance and one section outlet, and the cylinder sleeve internal diameter is increased, and has solved the superpressure phenomenon of two, three ends of existing high-purity high pressure hydrogen reciprocal compressor.

Description of drawings

Fig. 1 is the work block diagram of a kind of high-purity high pressure hydrogen of the utility model reciprocal compressor.

Among the figure, 1. one section, 2. two sections, 3. three sections, 4. four sections, 5. one section entrance, 6. one section outlet, 7. a pipeline.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The utility model provides a kind of high-purity high pressure hydrogen reciprocal compressor, as shown in Figure 1, high-purity high pressure hydrogen reciprocal compressor comprises one section 1, two section 2, three sections 3 and four sections 4, also comprise a pipeline 7 one time, a described pipeline 7 two ends connect respectively described one section entrance 5 and one section outlet 6.

Described four section 4 cylinder sleeve internal diameter is 120mm, and piston ring is 14 groups.

In the work, when hydrogen from one section outlet 6 out the time, a part of hydrogen is got back to again one section entrance 5 by a pipeline 7, has reduced two section 2 pressure.Because four section 4 cylinder sleeve internal diameter increases and piston ring increases, so increasing and bear pressure, four section 4 pressure increases, such three section 3 pressure reduces with regard to corresponding.

Like this, the superpressure phenomenon of two, three ends of existing high-purity high pressure hydrogen reciprocal compressor is resolved.
