Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of non-maintaining complex filter.
Background technology
At present, sampling unit mainly is made up of sampling pipeline and filter in the analytical system of using at home, therefore, and the quality that filter uses, the normal operation that the length in life-span all has influence on whole system.Thus, filter is the core component of analytical system.But the purge mode of numerous filters of domestic present use is to sweep plugged sereen and pipeline through the direct blowback of compressed gas, therefore, and in use; Filter usually can blocking surface; And between the filter gap, form and harden, it is not high to make it reverse gas cleaning efficient, and long-term use need often remove cleaning; Maintenance workload is big, and engineering cost is high.
Another reason is that the filter of former domestic use is not done rigorous analysis to appearance gas dust granularity filter distribution; But the requirement of all filtrations is all placed on the filter; Cause filter loading overweight, influence function of use, do not accomplish that classification bears; Classified filtering filters target and clearly acts on.
Because above-mentioned two main causes cause the analytical system operation conditions of use at present not ideal.
The utility model content
The purpose of the utility model then is the deficiency to above-mentioned prior art, and providing a kind of can use for a long time, is difficult for stopping up and dismountable non-maintaining complex filter.
The technical scheme of the utility model is:
A kind of non-maintaining complex filter; Comprise filter kernel, filter exocoel and heating temperature control device; The filter exocoel is sleeved on filter kernel outside, is provided with the heating temperature control device in filter exocoel outside, it is characterized in that also comprising quick-release arrangement; Be provided with screen filtration tube, ceramic filter filter core in the filter kernel and run through the filter appearance tracheae that connects the ceramic filter filter core; Also be provided with out kind pore and shunting air chamber on the filter exocoel, quick-release arrangement is arranged on shunting air chamber top, and filter appearance tracheae top is provided with a kind tracheae air-vent.
Said screen filtration tube is arranged on the outside of ceramic filter filter core.
Said ceramic filter filter core is that corundum is made, and its filtering accuracy is 2 μ, and said ceramic filter filter core has been done surface-coated.
The material of said screen filtration tube adopts ceramic material, stainless steel, powder metallurgy material, stainless steel felt or glass cartridge filter material.
Said screen filtration tube is the flexible filter screen of dense form stainless steel, and its filtering accuracy is 5 μ-10 μ.
The beneficial effect of the utility model:
The utility model filter has solved gas sampling both at home and abroad at present, the water quality sampling and analyzing filter is prone to obstruction, not easily detachable present situation; Have application prospect wide, use face width, be suitable for the big characteristic of dust; Be applicable to that gas analysis system is in sampling process; Especially be applied in the high dust sampling process, this device also can be applied in the water quality analytical system field.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in 2.
A kind of non-maintaining complex filter; Comprise filter kernel, filter exocoel 4 and heating temperature control device 6; Filter exocoel 4 is sleeved on filter kernel outside, and heating temperature control device 6 is located at filter exocoel 4 outsides, it is characterized in that also comprising quick-release arrangement 10; Be provided with screen filtration tube 1, ceramic filter filter core 2 in the filter kernel and run through the filter appearance tracheae 3 that connects ceramic filter filter core 2; Also be provided with out kind pore and shunting air chamber 8 on the filter exocoel 4, quick-release arrangement 10 is arranged on shunting air chamber 8 tops, and filter appearance tracheae 3 tops are provided with a kind tracheae air-vent 5.Screen filtration tube 1 is arranged on the outside of ceramic filter filter core 2.Said ceramic filter filter core is that corundum is made, and its filtering accuracy is 2 μ, and said ceramic filter filter core has been done surface-coated.The material of screen filtration tube 1 adopts ceramic material, stainless steel, powder metallurgy material, stainless steel felt or glass cartridge filter material.The screen filtration tube is the flexible filter screen of dense form stainless steel, and its filtering accuracy is 5 μ-10 μ.
The filter kernel of the utility model adopts layering filter type step by step, the dust that the outer screen filter cartridge is thicker, the dust that internal layer ceramic filter filter element filtering is thinner; Prevent that filter is because of filtering not as good as result in blockage; The screen filtration tube adopts flexible stainless steel cloth to process, when elevated pressures purges, because under the differential pressure action inside and outside the screen cloth; Screen cloth will have certain expansion; Thereby make the screen cloth gap become big, make inside and outside the reaching of screen cloth come off more easily, purge efficient and be greatly improved attached to the particles such as dust on the screen cloth.The quick-release arrangement that the filter of the utility model is portable makes when changing whole filter kernel, to need not to dismantle the relevant connection pipeline, tool free, and change the back good sealing effect.The utility model filter and blow device all are equipped with the outer container of rain-proof dust-proof, make the application scenario more extensive.
During sampling, analyze magnetic valve 16 and open, blowback magnetic valve 17 cuts out; Gather appearance gas through sampling pipe, gas gets into from the air inlet 12 of adpting flange 11, through screen filtration tube 1; Filter out big dust particle wherein, will filter out 90% the above dust of 5 μ herein, order gets into candle 2 subsequently; Filter out remaining most of fine dust through candle 2; Remaining particle dust will be accomplished final the filtration by other filters in the pretreatment unit, make gas can reach abundant cleaning, guarantee the safe handling of analysis meter.When gas through behind the candle 2, get into shunting air chamber 8 through filter appearance tracheae, be sent to pretreatment unit through the outlet of appearance gas through sampling line again, among Fig. 1 arrow points for sampling up-to-date style air-flow to.Shunting air chamber 8 mainly is to design for conveniently fast disassembling.
When the utility model being carried out the blowback cleaning, the blowback air stream is just in time opposite, and analyze magnetic valve 16 and close this moment; Air blowing magnetic valve 17 is opened, and blowback air enters into shunting air chamber 8 by going out kind pore 9, arrives the inside of candle 3 again through air-vent 5; Candle is purged; Dispose attached to the dust on the ceramic element and other pollutants, pass through screen filtration tube 1 again, dust all in the filter etc. is blown into flue 13 through the air inlet on the adpting flange 11 12.Because the blowback air flow is big, adopt constant temperature pulse gas mode to purge and cause the dust that holds of each filter to turn back to sampling conduit by former road, the constant temperature pulse backblowing reaches the purpose of deashing.
The undeclared part of other that relates in the utility model all adopts prior art to realize.
