Abstract
The utility model relates to a three-stage filter which comprises a tank body consisting of an inlet and an air outlet; three stages of filters, i.e. a baffle filter, a cooling filter and a filter element filter, are subsequently arranged in the tank body from down to up. Compared with the prior art in which only the filter element filter is used, the three-stage filter is applicable in dehydration to the gas with quite high temperature and water content, and has wide scope of application. In addition, after the gas is filtered through the first two stages of filters, the filter element load in the third stage of filter element filter is much smaller than that of the traditional structure, so the service life of the filter element is longer.
Description
Technical field
The utility model relates to and being used in a kind of gas generation the dewater filter of oil removing of mist.
Background technology
Traditional filter generally includes the tank body with air inlet and gas outlet, is provided with the filter core that is used to filter moisture in the tank body, only relies on the interior filter core of filter to carry out oil removing and dewaters.The life-span of the filter core in the filter of this structure is shorter usually, and under the situation that particularly gas temperature in entering filter is higher, water content is bigger, water removal effect is undesirable, makes that the steam in the mist is very easily brought in the downstream component by gas.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of tertiary filter, and it can be applicable to that the gas higher to gas temperature, that water content is higher dewaters, and service life applied widely and filter core is longer.
The utility model can be implemented by the following technical programs:
A kind of tertiary filter, it comprises the tank body with air inlet and gas outlet, be disposed with baffle plate filter, cold filtration device in the described tank body from the bottom to top, cross filter core filter three-stage filtration device, described baffle plate filter comprises the baffle plate that is horizontally set on described air inlet top; Described cold filtration device comprises the screen pipe that is used for logical mist and is used for the annular seal space of the logical described screen pipe of water quench that described screen pipe and described annular seal space are isolated mutually; The described filter core filter of crossing comprises a plurality of filter cores that are arranged on vertically in the described tank body.
The airintake direction of described air inlet is the tangential direction of the inwall of described tank body.
Also be provided with the cooling water inlet and the coolant outlet that are connected with described annular seal space on the described tank body.
The bottom of described tank body is provided with sewage draining exit, and described gas outlet is arranged on the top of described tank body.
Described filter core is the corundum filter core.
Described screen pipe is arranged in the described annular seal space vertically.
Compared with the prior art the utility model has following advantage:
Owing to be disposed with the baffle plate filter from the bottom to top in the described tank body, the cold filtration device, cross filter core filter three-stage filtration device, if water content is higher in the unstrpped gas, most of moisture can be amassed to the sewage draining exit place of bottom and remove behind the baffle plate of process baffle plate filter, enter into the cold filtration device then, logical cooling water in the annular seal space of cold filtration device, logical mist and cooling water and gas are isolated mutually in the screen pipe, when unstripped gas has uniform temperature, water condensation in the high-temperature gas can be got off flow to the ponding dish through the secondary type of cooling, water be discharged by sewage draining exit.Removed most of moisture through the unstrpped gas after the above-mentioned dual stage filter apparatus, the last corundum that passed through again in the filter core filter is crossed filter core and carried out the afterbody processed, and is better through the gas dewatering effect of three-stage filtration.
Compared with prior art, the utility model is applicable to that the gas higher to gas temperature, that water content is higher dewaters, and is applied widely.And because gas is little more a lot of than traditional structure at the filter core load of crossing in the filter core filter of the third level through after the filtration of preceding dual stage filter apparatus, so the service life of filter core is longer.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the vertical view of accompanying drawing 1;
Accompanying drawing 3 is a filter structure schematic representation of the prior art;
Wherein:
1, air inlet; 2, gas outlet; 3, tank body; 4, baffle plate filter; 41, baffle plate; 5, cold filtration device; 51, annular seal space; 52, screen pipe; 6, cross the filter core filter; 61, filter core; 7, cooling water inlet; 8 coolant outlets; 9, sewage draining exit.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated:
As shown in Figures 1 and 2, a kind of tertiary filter, it comprises the tank body 3 with air inlet 1 and gas outlet 2, is disposed with baffle plate filter 4, cold filtration device 5 in the described tank body 3 from the bottom to top, crosses filter core filter 6 three-stage filtration devices.
Described baffle plate filter 4 comprises the baffle plate 41 that is horizontally set on described air inlet 1 top; Described cold filtration device 5 comprises screen pipe 52 that is used for logical mist and the annular seal space 51 that is used for the logical described screen pipe 52 of water quench, described screen pipe 52 is isolated mutually with described annular seal space 51, and described screen pipe 52 is arranged in the described annular seal space 51 vertically; The described filter core filter 6 of crossing comprises a plurality of corundum filter cores 61 that are arranged on vertically in the described tank body 3.
Also be provided with the cooling water inlet 7 and the coolant outlet 8 that are connected with described annular seal space 51 on the described tank body 3.
The bottom of described tank body 3 is provided with sewage draining exit 9, and described gas outlet 2 is arranged on the top of described tank body 3.
The airintake direction of described air inlet 1 is the tangential direction of the inwall of described tank body 3, therefore unstrpped gas forms the whirlwind shape entered the tank body of filter by air inlet 1 after, if the gas of whirlwind shape is higher through impingement baffles 41 back water content, the baffle plate 41 back most of moisture of process baffle plate filter 4 can be amassed to sewage draining exit 9 places of bottom and remove, enter into cold filtration device 5 then, logical cooling water in the annular seal space 51 of cold filtration device 5, logical mist and cooling water and gas are isolated mutually in the screen pipe 52, when unstripped gas has uniform temperature, water condensation in the high-temperature gas can be got off flow to the ponding dish through the secondary type of cooling, water be discharged by sewage draining exit 9.Removed most of moisture through the unstrpped gas after the above-mentioned dual stage filter apparatus, the corundum filter core 61 that passed through again in the filter core filter 6 at last carries out the afterbody processed, and is better through the gas dewatering effect of three-stage filtration.
Compared with prior art, the utility model dewaters applicable to the gas higher to gas temperature, that water content is higher, and the scope of application is wider. And because gas is little more a lot of than traditional structure at the filter core load of crossing in the filter core filter of the third level through after the filtration of front dual stage filter apparatus, so the service life of filter core is longer, and service life is longer more than 2 times than old structure usually.
