Multifunctional high pressure gas safety purifier

Abstract

The invention discloses a multifunctional high-pressure gas safety purifier which comprises a purifier body, an upper cover, a filter screen, an inlet joint, outlet joints and a blow-down valve, wherein the filter screen is arranged on the middle part of the purifier body; the upper cover arranged is arranged on the top of the purifier body; the blow-down valve and inlet joint are respectively arranged on the bottom of the purifier body; the outer wall of the purifier is provided with the two outlet joints; the filter screen is in a cup structure; a gas inlet channel is arranged between the outer wall of the filter screen and the inner wall of the purifier body; the inlet joint is communicated with the gas inlet channel; the outlet of the inlet joint is positioned on the outer side of the side wall of the filter screen; and the gas inlet direction is parallel to the side wall of the filter screen. The multifunctional high-pressure gas safety purifier can effectively prolong the service life of the filter screen, solves the potential safety hazard of misoperation due to blow-down decontamination, enhances the safety, performs function integration innovation, reduces the use space, solves the problem of insufficient space inside the gas dispenser, lowers the product cost and enhances the production efficiency.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas purification, in particular to a multifunctional high-pressure gas safety purifier. Background technique [0002] As people's awareness of green environmental protection continues to increase, green and environmentally friendly fuels are also increasing with each passing day. As far as natural gas is concerned: at present, natural gas accounts for 4.6% of my country's primary energy consumption, which is far behind the international average (23.8%). big. At the same time, with the in-depth development of urbanization in my country and the continuous expansion of urban population, the demand for natural gas will also increase day by day. Accelerating the development of natural gas and increasing the proportion of natural gas in my country's primary energy consumption structure can significantly reduce the emission of greenhouse gases such as carbon dioxide and fine particulate matter (PM2...

AI Technical Summary

Problems solved by technology

[0005] (1) The service life of the filter screen is short: the main reason is that the position design of the air inlet is unreasonable, and the normal pressure of compressed natural gas is > 20Mpa. In addition, if there are impurities in the pipeline, it needs to be purged and discharged. Frequent switching of the inlet ball valve connected to the inlet joint is more likely to cause serious deformation of the filter and make the filter invalid.

As a result, the filling machine breaks down. If it is light, replace the filter screen, and if it is serious, it will damage the filling machine and affect the normal operation of the filling station.

[0006] (2) There is a potential safety hazard of misoperation in purging and sewage discharge: due to the structure of the whole machine, the purging screw is at the bottom of the gas dispenser, and it is not easy to see during operation. Loosen the purge screw for sewage discharge. During the process of loosening the screw, the operator will habitually stick his fingers to the end of the hexagonal head of the screw. If the screw is loosened at this time, the high-pressure gas inside the filter will instantly shoot On the finger, puncture the finger, causing a personal injury accident

[0007] (3) Single function, not easy to install: with the continuous updating of technology and the development of society, the existing filters are no longer fully applicable

Due to the restrictions on the dimensions of the dispenser, its internal space is narrow, and it is very inconvenient to install pipelines

[0008] In addition, since the natural gas pressure in the natural gas filling machine is as high as 22MPa or more, general filters (such as: natural gas filters for automobiles, gas pipeline filters, etc.), even if the filtering effect is good, are not suitable for natural gas filling. machine
