Description
Technical field
The utility model relates to cleaner technical field, is specifically related to use ceramic element cleaner.
Background technology
In the preparation process of industrial gasses, from the unstripped gas gas processed stage to final compression compound probability gas, need to carry out udst separation to unstripped gas.In petrochemical industry, to the normally used gas-liquid separation technique of the purification of unstripped gas, be that the unit equipment that adopts cyclone dust collectors to add electrostatic precipitator carrys out dedusting mostly, first by cyclone dust collectors, the big dust particle in unstripped gas is tentatively filtered, by electrostatic precipitator, carry out final dusting again, the method of this two-stage dust removal can effectively be removed the impurity such as moisture in unstripped gas, acid mist, dust, tar, but the use of electrostatic precipitator need to provide high-voltage electrostatic field, need to consume a large amount of electric energy; In prior art, also there is the unit equipment that adopts cyclone dust collectors to add ceramic filter-element dust collector to carry out dedusting, the method of this two-stage dust removal equally can be effectively to unstripped gas dedusting, and ceramic element has corrosion resistant, resistant to elevated temperatures character, thereby range of application is wider, but requiring high occasion in gas purification, the mode of ceramic element dedusting also has improved space.
Utility model content
The applicant improves for above-mentioned shortcoming of the prior art, provides a kind of existing ceramic filter-element dust collector is carried out to improved dust arrester, and it can carry out effectively and high-effective dust-removing unstripped gas.
The technical solution of the utility model is as follows:
Dust arrester, comprise shell body, air inlet and air outlet, in shell body, be provided with ceramic filtering device, the bottom of shell body is provided with flue-dust retainer, on shell body inwall, be connected with woven wire supporting construction, woven wire supporting construction inside is equipped with filter material layer, and filter material layer is between ceramic filtering device and air inlet.
Its further technical scheme is:
Described woven wire supporting construction comprises upper and lower double layer of metal silk screen, and described woven wire is fixed on shell body inwall, and filter material layer is located between described upper and lower double layer of metal silk screen.
Described air inlet place is provided with pressue device.
Described pressue device adopts force (forcing) pump.
Technique effect of the present utility model:
The utility model, by being secondary filter by filtering improvement of existing ceramic filter-element dust collector, has improved the filter effect of device; After the utility model also can be located at cyclone dust collectors, after the preliminary filtration of cyclone dust collectors, then carry out secondary filter by the utility model, come to three-stage filtration, compare existing cascade filtration of accompanying general cyclone dust collectors, filter effect is more obvious; By going out to arrange pressue device at air inlet, can increase at any time raw gas pressure, improve the flow velocity of unstripped gas in crust of the device body, make impure unstripped gas by high speed Brownian movement, improve the separative efficiency of impurity, reach the object of high-efficient purification gas, make the utility model be applicable to the high occasion of gas purification requirement; The utility model has increased filter material layer, in order not affect the flow velocity of unstripped gas, uses the little woven wire of resistance as the skeleton that supports filtrate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1, the utility model comprises the air inlet 2 of shell body 1, bottom and the air outlet 3 of top, in shell body 1, be provided with ceramic filtering device 4, ceramic filtering device 4 is supported in shell body 1 by gripper shoe 9, the bottom of shell body 1 is provided with flue-dust retainer 8, on shell body 1 inwall, be connected with woven wire supporting construction 5, woven wire supporting construction 5 inside are equipped with filter material layer 6, and filter material layer 6 is between ceramic filtering device 4 and air inlet 2.
Particularly, described woven wire supporting construction 5 comprises upper and lower double layer of metal silk screen, described upper and lower double layer of metal silk screen is fixed on shell body 1 inwall, filter material layer 6 is located between described upper and lower double layer of metal silk screen, filtrate in filter material layer 6 can be according to the temperature of unstripped gas and character, selecting the material of filtrate, can be silicate aluminum board, rock wool, glass fibre etc., and the scope of selection is wide.
Further, in order to improve the flow velocity of air inlet 2 place's unstripped gas, the speed of the Brownian movement of the impurity that improves unstripped gas and contain in shell body 1, thereby the separating rate of impurities in acceleration unstripped gas, at described air inlet, 2 places are provided with pressue device 7, and described pressue device 7 specifically can adopt force (forcing) pump.
The method of operation of the present utility model is as follows:
The unstripped gas that contains impurity or process cyclone dust collectors carry out the preliminary unstripped gas afterwards that filters in the shell body 1 of air inlet 2 accesss to plant, unstripped gas is introduced into filter material layer 6, swiftly flowing unstripped gas collides in filter material layer 6, the big dust particle impurity such as the solid in unstripped gas and large molecule acid mist are carried out to dust removal by filtration for the first time, after the preliminary filtration of filter material layer 6, pass through again ceramic filtering device 4, carry out secondary filter dedusting, can remove the remaining little molecule dust impurity in unstripped gas, the unstripped gas after purification enters next process by air outlet 3.
When the utility model is when gas purification requires high occasion to use, can open the pressue device 7 that air inlet 2 places arrange, to increase raw gas pressure, improve the flow velocity of unstripped gas in crust of the device body 1, make impure unstripped gas by high speed Brownian movement, improve the separative efficiency of impurity, reach the object of high-efficient purification gas.
The utility model is by being secondary filter by filtering improvement of existing ceramic filter-element dust collector, improved the filter effect of device, after the utility model also can be located at cyclone dust collectors, after the preliminary filtration of cyclone dust collectors, by the utility model, carry out secondary filter again, come to three-stage filtration, compare existing cascade filtration, gas purification degree reaches 99.9%, and filter effect is more obvious.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
