Abstract
The utility model discloses an on-line cleaning device for calcium carbonate filter cloth. The on-line cleaning device comprises a calcium carbonate filter in which a first cleaning area, a second cleaning area, a dry-suction area, a discharging area, a filter cloth regeneration area and a charging area are arranged, wherein the filter cloth regeneration area is provided with a water cleaning nozzle; the bottom of the filter is provided with an acid preparation tank; the acid preparation tank is connected with an acid proof pump; and the dry-suction area is provided with an acid cleaning nozzle along the radial direction of a filter disc and the nozzle is connected with the acid proof pump through a pipeline. A hydrochloric acid solution rapidly reacts with calcium carbonate on the filter cloth so as to dissolve the calcium carbonate; and then the calcium carbonate on the filter cloth can be effectively removed after the filter cloth is flushed by clear water. The on-line cleaning device is simple in structure, economical and reliable, simple to operate, high in efficiency and low in cost; and dismantlement is not needed.
Description
Technical field
The utility model relates to the cleaning of industrial filter cloth, specifically, relates to a kind of on-line cleaning device that filters the calcium carbonate filter cloth.
Background technology
At present, in industry, filter cloth has become application filter medium the most widely.Industrial filter cloth is to weave the filter medium that forms by natural fiber and synthetic fibers, is mainly used in Separation of Solid and Liquid and industrial dedusting.Yet, filter cloth in use, the material that is filtered can squeeze, adhere on the filter cloth, influences the filter effect of filter cloth, and material moisture is increased, and do not reach specification requirement, so filter cloth work must be cleaned behind some cycles.
Present method of cleaning the calcium carbonate filter cloth can be divided into on-line cleaning and off-line cleans two kinds, and the off-line cleaning need be dismantled and install filter cloth, wastes time and energy; And the conventional online cleaning is to utilize shower nozzle to spray running water to clean filter cloth, because calcium carbonate granule and filter cloth adhesion intensity are higher, the effect of on-line cleaning is also undesirable at present.
By on can know that the on-line cleaning device of above-mentioned existing calcium carbonate filter cloth on reality is used, obviously has defective and exists, and remain to be improved.
Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
Summary of the invention
The utility model is intended to overcome above-mentioned shortcoming, and a kind of on-line cleaning device of calcium carbonate filter cloth is provided, guarantee thoroughly to clear up the calcium carbonate on the filter cloth, and easy to operate.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts: a kind of on-line cleaning device of calcium carbonate filter cloth; Comprise the calcium carbonate filter, be provided with in the calcium carbonate filter that a Xi Qu, two washes the district, blots the district, discharge zone, filter cloth regeneration district, charging zone, be provided with the washing shower nozzle in the filter cloth regeneration district; In the bottom of said filter the complex acid groove is set; The complex acid groove connects acid-proof pump, along filter disc the pickling shower nozzle is set radially in the said district that blots, and said shower nozzle connects with acid-proof pump through pipeline.
The quantity of said pickling shower nozzle is 5.
Adopt the method for said apparatus on-line cleaning calcium carbonate filter cloth may further comprise the steps:
1 in the complex acid groove preparation 10-20% hydrochloric acid solution, the operation acid-proof pump is delivered to the zone position that blots of filter with the 10-20% hydrochloric acid solution, the pickling shower nozzle is with sectorial area spray irrigation filter cloth;
2 pickles blot the district through filter cloth and get back to the complex acid groove and carry out Recycling;
The filter cloth that 3 process acid solutions were washed continues to forward to the filter cloth regeneration district and further uses flushing with clean water, sets the speed of service of filter according to the cleaning situation;
4 according to filter cloth cleaning situation, circulation cleaning filter cloth 5-10 time.
Calcium carbonate on hydrochloric acid solution and the filter cloth reacts rapidly, melts away calcium carbonate, again through flushing with clean water, can effectively remove the calcium carbonate on the filter cloth.
The utility model is simple in structure, and economic and reliable is simple to operate, and efficient is high, and cost is low, need not dismantle.Use proof through reality, effect is remarkable, has promoted long period, the high-efficiency stable operation of process units.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a filter cloth acid cleaning process flow chart;
In the accompanying drawing: 1 one wash district 2 two washes district 3 and blots 4 pickling shower nozzles, 5 pickling districts, 6 discharge zones 7 washing shower nozzles, 8 filter cloth regeneration districts, district, 9 charging zones, 10 complex acid grooves, 11 acid-proof pumps.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, shown in Figure 2; In the calcium carbonate filter, be provided with one and wash district 1, two and wash district 2, blot district 3, discharge zone 6, filter cloth regeneration district 8, charging zone 9, be provided with washing shower nozzle 7, in filter cloth regeneration district 8 and wash the tail gas washing tower that the wash water in district 1 comes from carbonization workshop section; Washing lotion is gone to carbonization workshop section; Wash the district one and 1 can reclaim some industrial chemicals, two wash district 2 wash water come from the filter cloth washing water dashpot of filter, washing lotion is gone to the tail gas washing tower of carbonization workshop section; In the bottom of said filter complex acid groove 10 is set, complex acid groove 10 connects acid-proof pumps 11, along filter disc pickling shower nozzle 4 is set radially in the said district 3 of blotting, and said pickling shower nozzle 4 connects with acid-proof pump 10 through pipeline, has increased a pickling district 5 blotting to distinguish in 3 like this.
