Abstract
The invention discloses an on-line cleaning device of calcium carbonate filter cloth and a cleaning method. The device comprises a calcium carbonate filter; a primary cleaning zone, a secondary cleaning zone, an absorbing and drying zone, a discharging zone, a filter cloth regeneration zone and a charging zone are arranged in the calcium carbonate filter; a water wash spray head is arranged in the filter cloth regeneration zone; an acid distribution tank is arranged at the bottom of the filter; the acid distribution tank is connected with an acid proof pump; an acid wash spray head is arranged in the absorbing and drying zone along the radial direction of a filter disc; the acid wash spray head is connected with the acid proof pump through a pipeline; the cleaning method comprises the steps that 10 to 20 percent of hydrochloric acid solution is fed to the absorbing and drying zone of the filter, and the acid wash spray head sprays and washes filter cloth in a sectorial area; the filter cloth washed by the hydrochloric acid solution is further fed to the filter cloth regeneration zone to be washed through clear water, and the running speed of the filter is set according to the cleaning situation; and the filter cloth is circularly washed for 5 to 10 times according to the cleaning situation of the filter cloth.
Description
Technical field
The present invention relates to the cleaning of industrial filter cloth, specifically, relate to a kind of on-line cleaning device and cleaning method 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 in, 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 thoughts of the present invention is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the invention of above-mentioned defective finally.
Summary of the invention
The present invention is intended to overcome above-mentioned shortcoming, and a kind of on-line cleaning device and cleaning method 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 present invention adopts: a kind of on-line cleaning device of calcium carbonate filter cloth comprises 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 be 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, 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 present invention 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 a structural representation of the present invention;
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 present invention 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.
The method of 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;
