Description

Technical Field

[0001] The utility model relates to the field of high-pressure natural gas, in particular to a high-pressure natural gas transmission and dust removal system. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas from a mining site or processing plant to a city gas distribution center or industrial enterprise user. Using a natural gas pipeline to transport natural gas is a common way to transport natural gas. However, due to the large amount of dust and impurities in the natural gas well, these dust and impurities, driven by high-pressure natural gas, will cause high-speed erosion to the equipment. When the erosion time accumulates for too long, it will cause serious wear on the wall of the equipment and even cause accidents. In severe cases, the gathering and transportation equipment will be directly pierced, resulting in natural gas leaks and casualties and other complex accidents. Therefore, in order to prevent these dust and impurities from entering the equipment, it is necessary to install a dust removal device inside the pipeline.

[0003] In existing dust removal equipment, the installation and removal of multiple filters are not performed in a unified manner, but a single filter is installed and removed in turn, which greatly reduces work efficiency. In addition, the filter is directly set in the dust removal pipeline and its stability is not guaranteed when filtering and removing dust from natural gas. Utility Model Content

[0004] The purpose of the utility model is to provide a high-pressure natural gas transmission dust removal system, which solves the problem in the prior art that multiple filters cannot be installed and disassembled at the same time, affecting work efficiency, while also ensuring the stability of the filter when filtering and dusting natural gas.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-pressure natural gas transmission dust removal system, comprising a base, a dust removal pipe is fixedly connected to the upper side of the base, an air inlet pipe is fixedly connected to the left side of the dust removal pipe, an air outlet pipe is fixedly connected to the right side of the dust removal pipe, fixed blocks are arranged on both sides of the dust removal pipe, and a plurality of openings are arranged above the dust removal pipe. A filter screen bracket penetrates the plurality of openings, a filter screen is arranged inside the filter screen bracket, the upper ends of the filter screen brackets are fixedly connected to the upper plate, bolts are arranged on both sides of the upper plate, and the bolts are threadedly connected to the fixed blocks.

[0006] As a further description of the above technical solution: a first limiting plate is fixedly connected to one side of the filter bracket.

[0007] As a further description of the above technical solution: a handle is fixedly connected above the upper plate.

[0008] As a further description of the above technical solution: a first groove and a second groove are provided on one side of the filter bracket, and a spring is fixedly connected to one side of the first groove.

[0009] As a further description of the above technical solution: the other end of the spring is fixedly connected to the second limit block, and the other side of the second limit block is fixedly connected to the first limit block and passes through the first groove and the second groove.

[0010] As a further description of the above technical solution: one side of the filter screen is fixedly connected to a third limiting block, and a third groove is arranged inside the third limiting block.

[0011] The utility model has the following beneficial effects:

[0012] 1. Compared with the existing technology, the high-pressure natural gas transmission dust removal system realizes the function of installing and removing multiple filters at the same time by setting a handle, an upper plate, and a filter bracket, and can clean and replace multiple filters at the same time, thereby improving work efficiency;

[0013] 2. Compared with the prior art, the high-pressure natural gas transmission and dust removal system stably connects the filter bracket and the dust removal pipe, the filter and the filter bracket by setting a fixing block, a bolt, a first limit plate, a second groove, a second limit block, a first limit block, a third limit block, and a third groove, so that the filter bracket and the filter will not be displaced when the device is filtering and dust removing natural gas, thereby ensuring the stability of the device.
