Abstract
The invention discloses a sealing method for a vacuum belt-typed filter, comprising that a sealing water pipeline which communicates a pipeline from an acid returning pump to a reaction trough is arranged on a pipeline between a sealed water valve and a vacuum box of the vacuum belt-typed filter; and the sealing water pipeline is provided with a valve. The sealing water valve pipeline is provided with a sealing water booster pump. All valves adopt stop valves. The pipelines at all sealing positions of the vacuum box are designed as stainless steel pipes, with the joint adopting stainless steel quick-assembly joint. The sealing method of the invention has the advantages of small abrasion of friction belts, long service life of equipment, productivity improving, energy saving and loss reducing.
Description
Technical field
The present invention relates to a kind of encapsulating method, relate in particular to a kind of encapsulating method of vacuum band-type filter machine.
Background technology
Band of phosphate fertilizer industry vacuum band-type filter machine vacuum box friction at present and rubber belt sealing medium adopting process water are as two 50m of PPA device
2The former design vacuum box of band filter be fresh water (FW) sealing, its design discharge 2m
3/ h.Because of limited by domestic machining accuracy, filter vacuum box friction band is 0.8cp (centipoise) because of the viscosity of water in actual production, its flow is too small, pressure is not enough, can not form moisture film, increased the frictional force between vacuum box friction band and the adhesive tape on the contrary, cause filter noise in running excessive, the vacuum box friction is taken out of and is now repeatedly broken, and the vacuum slide unit has the heavy wear phenomenon.Actual sealing water must reach 8m
3/ h could satisfy the equipment service requirement, because of filter is worked under vacuum condition, fresh water (FW) almost all is inhaled into and filter acid is caused dilution in the vacuum box, makes that acid is dense to drop to 41.5% from intrinsic 45.8%, and sour diluted meeting causes concentrated energy consumption to increase, and device capbility descends.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of friction belt wear little, service life of equipment is long, and production capacity improves, the encapsulating method of energy-saving and cost-reducing vacuum band-type filter machine.
A kind of encapsulating method of vacuum band-type filter machine comprises: on the pipeline between the vacuum box of sealing penstock and vacuum band-type filter machine, draw the connection of a sealing waterpipe from returning the pipeline of sour pump to reactive tank, and establish valve at the sealing waterpipe;
On sealing penstock pipeline, establish sealing water booster pump.
The encapsulating method of above-mentioned vacuum band-type filter machine, wherein: all valves adopt stop valve.
The encapsulating method of above-mentioned vacuum band-type filter machine, wherein: the pipe design that vacuum box is respectively distinguished sealing place is a stainless steel tube, the stainless steel ready-packaged joint that joint adopts.
The present invention compared with prior art has tangible advantage and effect.By above technical scheme as can be known, the phosphoric acid,diluted that returns acid filter-is washed in employing, this phosphoric acid,diluted is originally and returns reactive tank, now get most of filter medium replacement fresh water (FW) that is, neither can impact whole technology, solve sour diluted problem again, reduced the concentration systems steam consumption, thereby reduced energy consumption; Phosphoric acid viscosity 1.5cp (centipoise) and lubricity are all good than water, are easy to generate lubricating film, make the friction belt wear little, and service life of equipment is long, and production capacity improves.The setting that seals the water booster pump simultaneously can guarantee to seal required pressure.
Description of drawings
Accompanying drawing is a process chart of the present invention.
The specific embodiment
A kind of encapsulating method of vacuum band-type filter machine comprises: on the pipeline between the vacuum box of sealing penstock and vacuum band-type filter machine, draw the connection of a sealing waterpipe from returning the pipeline of sour pump to reactive tank, and establish valve at the sealing waterpipe;
On sealing penstock pipeline, establish sealing water booster pump.
All valves adopt stop valve.
The pipe design that vacuum box is respectively distinguished sealing place is a stainless steel tube, the stainless steel ready-packaged joint that joint adopts.
During operation, close earlier and filter one and wash and return the valve A of acid to the sealing water pipeline, open the sealing penstock after starting sealing water booster pump, sealing water enters in the friction band chute of vacuum box.Start vacuum band-type filter machine; After treating the vacuum band-type filter machine charging, sour pump is returned in operation, closes the sealing penstock, stop sealing the water booster pump, open filtration one and wash acid, by valve A control sealing medium flow, pressure to the valve A that seals on the waterpipe, switching sealing means is the acid sealing, satisfies filter vacuum seal requirement.
