Abstract
The utility model discloses an enhancedpartitioned back-blowing and filtering device. The device comprises a filtering unit and a back-blowing unit, wherein the filtering unit comprises a filter case, filter elements and a tube plate, the tube plate is arranged at the upper part of the filter case, the filter elements are fixed on the tube plate and distributed below the tube plate, the upper part of the filter case is connected with a gland in a sealed manner, the inside of the gland is evenly divided by steel plates into multiple cavities opposite to the tube plate, a back-blowing gas inlet tube is arranged in each cavity, the lower part of each back-blowing gas inlet tube goes deep above the tube plate, and the upper part of each back-blowing gas inlet tube is connected with a back-blowing gas pipelinethrough a gas inlet valve. With the adoption of the device, the relatively ideal filtering and back-blowing effect can be realized, circulating filtration and back-blowing of one cavity is conducted separately, the back-blowing effect is better, the filtering and back-blowing efficiency is high, meanwhile, the regeneration capacity of the filter elements is improved, and service lives of the filter elements are prolonged.
Description
Technical field
The utility model relates to a kind of blowback filter, is specifically related to a kind of enhancement mode subregion blowback filter.
Background technology
In existing fluid purification impurity removing technology, the serviceability of air-flow back-flushing technique to filter core long-term stability and the continuous operation of equipment play an important role, but in general fluid purification knot screen (as shown in Figure 1), the entrance of contaminated liquids is generally positioned at the tank body side lower part of filtering container, adopt the straight length pattern of joining with filtering container diameter, by this filter medium entrance, contaminated liquids is introduced in filtering container, the solid particle that screen pipe contains contaminated liquids is blocked in the outer surface of filter element, liquid after purifying by filter element is discharged by the outlet of contaminated liquids, outlet is generally positioned at the tank body upper lateral part of filtering container, the impurity of screen pipe outer surface will emit its purging by purge gas, blowback air entrance is generally positioned at the tank body upper lateral part of filtering container.The mode that this fluid purification knot screen adopts filtration, blowback, blowdown to carry out simultaneously, the DeGrain of the amount that its weak point is purge gas to all filter element blowbacks, easily exist part filter element pulse cleaning thoroughly and impurity blowback unclean.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of enhancement mode subregion blowback filter, and this blowback filter can improve the power of regeneration of filter element effectively, improves and filters blowback efficiency and reduce filter element blowback number of operations and expense.
The technical solution of the utility model is: a kind of enhancement mode subregion blowback filter, it is characterized in that comprising filter element and blowback unit, described filter element comprises filter housings, filter element and tube sheet, wherein tube sheet is arranged at the top of filter housings, filter element is fixed on tube sheet and is arranged in the below of tube sheet, the sidewall of filter housings bottom is provided with medium inlet road, the bottom of filter housings is provided with blow-off line, top and the end socket of filter housings are tightly connected, the top of this end socket is provided with media outlet pipeline, bottom at media outlet pipeline is provided with drain, described end socket inside is divided into multiple chambers relative with tube sheet by steel plate, in each chamber, be respectively equipped with blowback air inlet pipe, the bottom of this blowback air inlet pipe is deep into the top of tube sheet, the top of blowback air inlet pipe is connected with purge gas pipeline by air intake valve.
The utility model compared with prior art has following beneficial effect: (1) the utility model can be realized comparatively desirable filtration blowback effect, carry out separately the circulating filtration blowback of a chamber, blowback effect is better, filter blowback efficiency high, improve the power of regeneration of filter element simultaneously, extended the service life of filter element; (2) the blowback number of operations of filter element is less, and needn't the device outer regeneration of filter core and changing too early, has reduced filter core investment and manual operation number of times, has reduced operating cost.
Brief description of the drawings
Fig. 1 is the structural representation of industrial contaminated liquids purifying and dedusting device in prior art, and Fig. 2 is structural representation of the present utility model, and Fig. 3 is the top view of Fig. 2.
Drawing explanation: 1, filter housings, 2, filter element, 3, tube sheet, 4, purge gas pipeline, 5, media outlet pipeline, 6, drain, 7, medium inlet road, 8, blow-off line, 9, chamber.
Detailed description of the invention
Describe by reference to the accompanying drawings embodiment in detail.A kind of enhancement mode subregion blowback filter, comprise filter element and blowback unit, described filter element comprises filter housings 1, filter element 2 and tube sheet 3, wherein tube sheet 3 is arranged at the top of filter housings 1, filter element 2 is fixed on tube sheet 3 and is arranged in the below of tube sheet 3, the sidewall of filter housings 1 bottom is provided with medium inlet road 7, the bottom of filter housings 1 is provided with blow-off line 8, top and the end socket of filter housings 1 are tightly connected, the top of this end socket is provided with media outlet pipeline 5, be provided with drain 6 in the bottom of media outlet pipeline 5, described end socket inside is divided into 6 chambers 9 relative with tube sheet 3 by steel plate, in each chamber 9, be respectively equipped with blowback air inlet pipe, the bottom of this blowback air inlet pipe is deep into the top of tube sheet 3, the top of blowback air inlet pipe is connected with purge gas pipeline 4 by air intake valve, in blowback running, open the air intake valve of one of them blowback air inlet pipe top, other air intake valve is closed, one by one the corresponding filter element 2 of each chamber 9 is carried out to blowback cleaning, until 6 chambers 9 are all complete by blowback, the advantage of blowback is like this, the filter element 2 of same present blowback 1/6th quantity of the blowback air scale of construction, greatly improve the power of regeneration of filter element 2, improve filtration blowback efficiency, obtain desirable filtration blowback effect, filter element blowback number of operations and operating cost are reduced.
More than show and described general principle of the present utility model; principal character and advantage; do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
