Groove I, the groove II of mutual cooperation are equipped with, closed plate is fastened in groove I, groove II, filling is aerobic in the sandwich
Change calcium.
The filtration system of existing combustion engine gas handling system is typically all used cooperatively using multistage filtering, and multistage filtering is not only tied
Structure is cumbersome, and the filter core of existing filter is fixedly connected with shell, it is impossible to dismounting and change.
It is logical that inlet channel of the present invention specifically refers to be formed between the side wall of closed shell and inlet end bottom
Road combustion gas is entered into closed shell by inlet channel；The sandwich specifically refer to filter core side wall be provided with internal layer and
Outer layer, internal layer and between be formed with interlayer, calcium oxide is arranged in interlayer；The calcium oxide is existing material, can absorb people
Moisture and sour gas in gas, moreover it is possible to intercept solid particle；The resilient clamp block I, resilient clamp block II are specifically referred to certainly
There can be the structure of contraction under pressure effect, can be the connector of elastomeric material, or spring and grip block；2 closings
Plate just by the spacing closing between closed shell and filter core, realizes the closing of closed shell outlet side.
The course of work of the invention：Combustion gas, into treatment is compressed to combustion gas in gas compressor, is pressed by admission line
Combustion gas after contracting is entered into closed shell by inlet channel, and because the other end of closed shell is closed, combustion gas can only be saturating
Cross the calcium oxide set in sandwich to enter into inside filter core, because calcium oxide is to the moisture and sour gas that are mixed with combustion gas
Solid particle is absorbed and is intercepted, thus the combustion gas entered into inside filter core is clean combustion gas, due to the closing of filter core one end,
Combustion gas after filtering is discharged by the beginning of filter core, reduces the pressure inside filter core, and constantly enters combustion gas in closed shell, because
And the pressure on the outside of filter core is more than inside pressure, outside forms pressure difference in filter core, and pressure difference causes combustion gas through the interlayer of filter core
Structure carries out filtration treatment.
Installation of the invention and unloading process：Remove closed plate, by filter core and blind end twisted with filter core fixed seat screw thread
Tightly（Can by setting outer pitch thread in filter core fixed seat, the blind end of filter core be provided with the cooperation of outer pitch thread
Pressure screw thread realizes that screw thread is tightened）, then closed plate is fastened in groove I, groove II, closed plate is in resilient clamp block I, elasticity
Be fixed between groove I, groove II under the clamping action of grip block II, 2 closed plates just by closed shell and filter core it
Between gap closing realize the closing of closed shell outlet side.
The present invention is by setting the filter core with sandwich, moisture in being provided with sandwich for absorbing combustion gas
With the calcium oxide of sour gas, outside forms pressure difference in filter core so that combustion gas penetrates into filter core inner side by filter core outside, realizes
Filtering to combustion gas, the combustion gas after filtering is discharged by the beginning of filter core, simple structure of the present invention, in this way, instant invention overcomes existing
The cumbersome problem of some filter apparatus configurations.
The present invention is by setting the resilient clamp block I, the resilient clamp block II that cooperate, resilient clamp block I, resilient clamp
Groove I, groove II are respectively arranged with block II, closed plate is realized under resilient clamp block I, the clamping action of resilient clamp block II
Closing, while filter core is tightened with filter core fixed seat using screw thread so that filter core is detachable, in this way, instant invention overcomes existing mistake
The filter non-detachable problem of device filter core.
Further, also including cooling system：Cooling water pipe is set by gas filter outer wall, in cooling water pipe
Supplement cooling water carries out cooling treatment.
Further, also including oil system：For the equipment in combustion engine gas handling system provides lubricating oil.
Further, filter core is hollow column construction or square structure, and the side wall of filter core is set to sandwich.
Further, the side wall of filter core is made of steel wire, and being sticked on steel wire has cloth.
The preferred kapok of cloth, nylon；The setting of steel wire can strengthen the structural stability of filter core.
Further, at least provided with 2, adjacent inlet channel is separated inlet channel by dividing plate.
Further, screen pack is provided with inlet end in closed shell.
The large particulate matter of combustion gas inlet side can be carried out interception filtering by screen pack, it is to avoid large particulate matter blocks filter core.
Further, the inlet end of closed shell is provided with joint I, and the beginning of filter core is provided with joint II.
Joint I, joint II are used to be connected filter with other associated devices.
Further, the beginning of filter core be connected with funnel structure, funnel structure it is interior without leave with filter core connection end to outlet
End gradually increases, and the joint II is connected with funnel structure.
The setting of funnel structure can have the exhaust velocity for increasing filter core, and further the pressure difference in the interior outside of increase filter core, improves
Filter efficiency.
Further, resilient clamp block I, resilient clamp block II are made of rubber.
