Description
Technical field
The present invention relates to a kind of gas-filtering device, be specifically related to a kind of gas-filtering device carrying out off-line blowback.
Background technology
Gas-filtering device dust granules when filtering can form one deck filter cake on the surface of filter core gradually, in order to remove the dust of cartridge surface, usually adopting blow-back purge mode, purging cartridge surface by extraneous gases at high pressure.At present, the structure of gas-filtering device comprises gas-filtering device shell and is arranged at the filter core group in gas-filtering device shell, described gas-filtering device shell by orifice plate be divided into the pure qi (oxygen) chamber on top and bottom Primordial Qi chamber (" Primordial Qi " refer to filtration before gas, " pure qi (oxygen) " refer to filtration after gas), the bottom in described Primordial Qi chamber is provided with the expansion chamber for dust settling, filter core group is arranged at the below of orifice plate, the top of described filter core group is provided with back-blowing device, described gas-filtering device is provided with the air inlet be connected with Primordial Qi chamber and the gas outlet be connected with pure qi (oxygen) chamber.Because Primordial Qi enters filter core endlessly from Primordial Qi chamber, make that the pure qi (oxygen) after by filter element filtering is also continual enters pure qi (oxygen) chamber, when gas-filtering device carries out blowback, the pure qi (oxygen) entering pure qi (oxygen) chamber can cause resistance to purge gas, thereby increase blowback difficulty, be difficult to be settled down to heavy grey room by the impact of the dust of cartridge surface of blowing off due to above-mentioned resistance, a period of time after-blow from the easy secondary of dust be attached to the surface of filter core, the dust that grain diameter is less even can block filter core hole, finally causes filter element filtering efficiency to reduce.
Summary of the invention
Technical problem to be solved by this invention there are provided one can overcome blowback resistance (" blowback resistance " refers to the resistance caused purge gas when pure qi (oxygen) enters pure qi (oxygen) chamber) and the gas-filtering device that can ensure continuous filtration.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
Gas-filtering device of the present invention comprises filter shell, comprise filter shell and be arranged at filter enclosure and be divided into the orifice plate in the Primordial Qi chamber of bottom and the pure qi (oxygen) chamber on top, two filter core groups are at least provided with below described orifice plate, the top of each filter core group is respectively equipped with the back-blowing device be connected with blowback source of the gas, described pure qi (oxygen) chamber is divided at least two separate chamber be isolated from each other, the back-blowing device described at least one is furnished with in each separate chamber, described each separate chamber is respectively equipped with the valve port for discharging pure qi (oxygen), described each valve port is provided with and controls separately its controlling organization opened and closed.Controlling organization can control to close to a few valve port, open at least one valve port simultaneously, Primordial Qi stops the chamber entering close port, purge gas can not be subject to the impact producing resistance when Primordial Qi enters when purging filter core corresponding to these chambers, the chamber opening valve port continues to carry out gas filtration, thus achieves the continuous operation maintaining gas-filtering device while overcoming blowback resistance.
As the further improvement of above-mentioned gas filter, be also provided with outlet chamber between described pure qi (oxygen) chamber and filter cover top portion, described outlet chamber is provided with the gas outlet be communicated with the gas-filtering device external world, and described each valve port is all communicated with this outlet chamber.Outlet chamber makes all to enter outlet chamber from the valve port pure qi (oxygen) out of each chamber, and discharges from the gas outlet outlet chamber.
Further, separated between adjacent separate chamber by vertical clapboard, separated between described each separate chamber and outlet chamber by diaphragm plate, each valve port is positioned on the diaphragm plate at corresponding separate chamber top.
Further, described controlling organization comprises the closure member be arranged on valve port and the cylinder controlling closure member opening and closing, and piston rod and the closure member of described cylinder are in transmission connection.Simpler compared to installing other control by the open and close of cylinder pneumatic control cover plate, use safety coefficient is higher.Particularly, described piston rod is in transmission connection through filter cover top portion and closure member.
Further, separated by vertical clapboard between described chamber, separated by diaphragm plate between described pure qi (oxygen) chamber and Primordial Qi chamber.
Adopt above-mentioned gas filter can overcome blowback resistance when carrying out reverse gas cleaning, and the continuous filtration of energy assurance device, do not need parking deashing.
