Abstract
The utility model discloses a clean filter of nitrogen gas, include: circular cleaning device, filter screen, entry reducing short circuit, export reducing short circuit, flange, filter screen are coniform, surface area greatly increased, and filter area improves greatly when nitrogen gas passes through the filter screen, has improved nitrogen gas filtration efficiency, also can also clean not demolising circular cleaning device, convenient and fast, and efficiency is higher.
Description
Technical Field
The utility model relates to a device relates to the chemical industry field, directly relates to a nitrogen gas clean filter.
Background
The sealed nitrogen used by the existing air separation unit enters the unit through a carbon steel pipeline by pressurization, fine particles easily enter along with the nitrogen, the stability and the safety production of the unit are not facilitated, and a nitrogen cleaning filter is very necessary.
SUMMERY OF THE UTILITY MODEL
The utility model aims at improving the cleanliness of the sealing gas medium before the sealing nitrogen enters the unit, and solving the problem of influencing the stable operation of the unit due to the sealing gas.
The purpose of the utility model is realized like this: a nitrogen cleaning filter comprising: circular cleaning device, filter screen, entry reducing short circuit, export reducing short circuit, flange, circular cleaning device sets up between entry reducing short circuit and export reducing short circuit to be connected through flange, the filter screen, it is coniform, and coaxial setting is in circular cleaning device, and the filter screen outward flange between through circular cleaning device and the export reducing short circuit is fixed.
Preferably, the nitrogen cleaning filter also comprises a back-blowing inlet pipe and a back-blowing outlet pipe, wherein the back-blowing inlet pipe is arranged on the outer wall of the outlet reducing short circuit and communicated with the outlet reducing short circuit; the back-blowing outlet pipe is arranged on the outer wall of the inlet reducing short circuit and is communicated with the inlet reducing short circuit.
Preferably, the screen is a 32 mesh screen.
The utility model has the advantages that:
the utility model discloses because circular cleaning device sets up between entry reducing short circuit and export reducing short circuit to be connected through flange, the filter screen, it is coniform, and coaxial setting is in circular cleaning device, and the filter screen outward flange is fixed through circular cleaning device and the flange between the reducing short circuit of export. The filter screen is conical, the surface area is greatly increased, the filtering area is greatly increased when nitrogen passes through the filter screen, and the nitrogen filtering efficiency is improved. When a large amount of dust is accumulated outside the filter screen, the air supply is stopped, then the connecting flange is disassembled, and the filter screen is replaced conveniently and quickly; the nitrogen cleaning filter also comprises a back-blowing inlet pipe and a back-blowing outlet pipe, wherein the back-blowing inlet pipe is arranged on the outer wall of the outlet reducing short circuit and communicated with the outlet reducing short circuit; the blowback outlet pipe sets up on import reducing short circuit outer wall, and be linked together with import reducing short circuit, when the filter screen outside gathers the dust, also can stop the air feed, close entry opposite sex short circuit and export opposite sex short circuit, open blowback inlet tube and blowback outlet pipe, let in flushing gas, wash away the filter screen, reach clean effect, after the cleanness finishes, close blowback inlet tube and blowback outlet pipe, open entry opposite sex short circuit, export opposite sex short circuit, normal work, and convenient for operation, need not to demolish circular cleaning device and also can clean, high convenience and high speed, and high efficiency.
Drawings
Figure 1 shows the structure schematic diagram of the nitrogen cleaning filter of the invention.
Fig. 2 shows a schematic structural view of the screen.
Detailed Description
The attached drawings 1-2 show the structure schematic diagram of the nitrogen cleaning filter of the utility model, and the utility model is further explained by combining the attached drawings 1-2:
a nitrogen cleaning filter comprising: circular cleaning device 1, filter screen 2, entry reducing short circuit 3, export reducing short circuit 4, flange 5, circular cleaning device 1 sets up between entry reducing short circuit 3 and export reducing short circuit 4 to be connected through flange 5, filter screen 2, it is coniform, and coaxial setting is in circular cleaning device 1, and 2 outward flanges of filter screen are fixed through circular cleaning device 1 and the flange 5 between the export reducing short circuit 4.
The nitrogen cleaning filter also comprises a back-blowing inlet pipe 6 and a back-blowing outlet pipe 7, wherein the back-blowing inlet pipe 6 is arranged on the outer wall of the outlet reducing short circuit 4 and is communicated with the outlet reducing short circuit 4; the back-blowing outlet pipe 7 is arranged on the outer wall of the inlet reducing short circuit and is communicated with the inlet reducing short circuit. The filter screen 2 is a 32-mesh filter screen.
When a large amount of dust is accumulated outside the filter screen 2, the air supply is stopped, then the connecting flange 5 is disassembled, and the filter screen 2 is replaced conveniently and quickly; also can stop the air feed, close entry reducing short circuit 3 and export opposite sex short circuit, open blowback inlet tube 6 and blowback outlet pipe 7, let in the flushing gas, erode filter screen 2, reach clean effect, clean the back that finishes, close blowback inlet tube 6 and blowback outlet pipe 7, open entry reducing short circuit 3, export opposite sex short circuit, normal work, convenient operation need not to demolish circular cleaning device 1 and also can clean, convenient and fast, and efficiency is higher.
