Abstract
The utility model relates to an ultra-filter of difluoromonochloroethane. The filter comprises a barrel, and a filter core which is arranged inside the barrel, wherein two ends of the filter core are respectively encapsulated inside the barrel through two filter nets; two ends of the barrel are connected with male and female flanges; the filter nets are locked and connected to the male and female flanges by gaskets; and the evaporated residue in the gas conveying process is effectively filtered out by adopting the barrel with the filter nets and the filter core between the male and female flanges and mounting the male and female flanges in a pipeline of a difluoromonochloroethane production system. The ultra-filter of difluoromonochloroethane is simple in structure, convenient and fast to assemble, install and maintain, low in use cost, good in connecting seal performance, good in filter effect and suitable for installation and use of a gas transmission pipeline in the field of chemical industry.
Description
Technical field
The utility model relates to a kind of accurate filter, is used for filtering the accurate filter of the evaporation of residual such as moisture, fixed gas, evaporation of residual, oxygen during specifically a kind of difluoromono-chloroethane is produced, and belongs to the fluorine chemical field.
Background technology
Difluoromono-chloroethane is the raw material of producing one of three large fluorine polymerization single polymerization monomers vinylidene, the manufacturer of vinylidene is very high to the difluoromono-chloroethane quality requirements both at home and abroad, particularly the evaporation of residual controls such as some Small Indicators such as moisture, fixed gas, oxygen content are very strict, and wherein in finished product, the evaporation of residual amount requires less than 15PPm.Have now in the system that produces difluoromono-chloroethane take Difluoroethane as raw material, reaction, degassed, rectifying are to the finished product storage tank, passed through in finished product filling pump pouring process by the finished product storage tank, all pipelines are carbon steel structure again, and the evaporation of residual amount in it is far longer than 15PPm.
Summary of the invention
For the large deficiency of finished product evaporation of residual amount in difluoromono-chloroethane production system in prior art, it is a kind of simple in structure, compact that the utility model provides, can effectively filter the evaporation of residual in induction system, good filtration effect, be convenient to install, safeguard, change difluoromono-chloroethane accurate filter easy to use
The technical solution adopted in the utility model is: a kind of difluoromono-chloroethane accurate filter, filter comprises cylindrical shell and is arranged at the interior filter core of cylindrical shell, it is characterized in that described filter core two ends are packaged in cylindrical shell through two filter screens respectively, the two ends of cylindrical shell all are connected with male and female flange, and filter screen is connected on male and female flange through pad locking.
Described filter core is medical absorbent cotton.
Described filter screen and pad conjoined structure.
Described filter screen is 80 ~ 100 purpose stainless steels or copper screen pack.
Described pad is provided with screw hole, and pad passes screw hole through bolt and is fixedly connected on male and female flange.
Described filter two ends are connected between difluoromono-chloroethane finished product storage tank and finished product filling pump on pipeline through male and female flange respectively.
Described filter core is filled full cylindrical shell.
The utility model has the advantages that:
1, filter adopts male and female flange to be connected between finished product storage tank and finished product filling pump on pipeline, final collection finished product is filtered, male and female flange is simple in structure, easy for installation in pipeline, and strong in sealing for tubing joints, can effectively improve the usage safety performance of filter;
2, screen pack and filter core are set in cylindrical shell, screen pack is installed on male and female flange by pad, is convenient to installation, the dismounting of screen pack and filter core, and periodic replacement screen pack and filter core guarantee effective filtration of filter;
3, screen pack adopts stainless steel or copper screen pack, corrosion resistance and good, and long service life is fit to chemical field and uses; Filter core adopts medical absorbent cotton, and the evaporation of residual such as the moisture during effectively filtering gas is carried, fixed gas, oxygen guarantee the evaporation of residual amount less than 15PPm, and medical absorbent cotton replacement cost are low, can often change, and are convenient to further reduce the evaporation of residual amount.
The cylindrical shell of mounting strap screen pack and filter core between the utility model filter employing male and female flange, and be installed on by male and female flange in the pipeline of difluoromono-chloroethane production system the evaporation of residual in its gas course of conveying is effectively filtered, it is simple in structure, assembling, install, safeguard convenient, use cost is low, connection sealing can be good, good filtration effect is fit to the chemical field gas transmission pipeline and installs and uses.
