Abstract

Provided is a gas filter most suitable for the purification and filtration of the natural gas, the coal gas, the liquefied petroleum gas and the gas medium without corrosion of the liquefied petroleum gas. The filter uses a cylinder body with an upper and a symmetric lower air inlet pipe, the gas enters the cylinder body through the radial gas hole of the lower air inlet pipe, which avoids the damage caused by gas directly acting on one part of the filter core, and will not cause the filter core damage and blockage in the air inlet position, the filter is not limited by width in assembly process. The filter is simple in structure, more flexible and convenient in assembly method, good in filtering effect, long in service life, provided with widely practicality.

Description

Gas filter
One, technical field
The utility model relates to gas filter, is particularly useful for the purification filtering of natural gas, coal gas, oil liquefied gas and non-corrosiveness gas medium thereof.
Two, background technology
The gas filter that uses generally can be divided into standard type, angle type at present; The angle type is divided into two kinds on horizontal type and vertical plane angle type again.When standard type is installed, import and export axis and the loop dead in line of main pressure regulator equipment, and angie type generally being contained in voltage adjusting device major loop corner, is that major loop has played an elbow effect when filtering, more than two kinds of patterns to use extreme in gas filtration extensive.But these three kinds of patterns all in filter core one side air inlet, easily cause local damage of air inlet place filter core and obstruction, and in assembling process, during as restricted width, slightly inadequate.
Three, technology contents
1. goal of the invention
In view of the deficiency that prior art exists, the purpose of this utility model provides a kind of simple in structure, and is easy to assembly, good filtration effect, the gas filter of long service life.
2. technical scheme
The utility model gas filter, it is made up of a cylindrical shell that is provided with lower inlet duct and last escape pipe, be provided with the filter core that leads to escape pipe in the cylindrical shell, the filter core bottom is provided with the bolt that compresses filter core, the cylindrical shell mouth down, the flange that oral area is provided with blind plate and is fixedly connected with blind plate, lower inlet duct pass blind plate and stretch in the cylindrical shell, and its head is provided with a plurality of radial air inlets hole.
3. technique effect
The utility model gas filter, be best suited for the purification filtering of natural gas, coal gas, oil liquefied gas and non-corrosiveness gas medium thereof, the cylindrical shell of lower inlet duct symmetry in the employing, gas enters cylindrical shell from the radially pore of lower inlet duct, avoid gas to directly act on a certain position of filter core and caused damage, compared with prior art, can not cause air inlet place filter core to damage stops up, and in assembling process, not being subjected to the restriction of width, it is simple in structure, the assembling mode is more flexible, good filtration effect, long service life has practicality widely.
Four, description of drawings
Accompanying drawing is the utility model gas filter structure chart.
Five, the specific embodiment
The utility model will be further described below in conjunction with an embodiment in the accompanying drawing:
A kind of gas filter of the utility model, it mainly is made up of cylindrical shell 3, filter core 2, last escape pipe 1 and lower inlet duct 6.The flange 4 that cylindrical shell 3 mouth downs, oral area are provided with blind plate 5 and are fixedly connected with blind plate 5, lower inlet duct 6 pass blind plate 5 and stretch in the cylindrical shell 3, and its head is provided with a plurality of radial air inlets hole.Last escape pipe 1 is located at the top of cylindrical shell 3, filter core 2 is located in the cylindrical shell 3, tracheae is concentric to be provided with passing in and out up and down, filter core 2 bottoms are provided with the bolt 7 that compresses filter core, gas from the radially pore of lower inlet duct 6 to entering cylindrical shell 3, gas leads to escape pipe 1 after filtering through filter core 2 uniformly in cylindrical shell 3.
