Abstract
The invention discloses a kind of cleaning method of Nash hytor fouling, comprise following operating procedure: taken apart by Nash hytor, adopt 8-10% hydrochloric acid solution soakage water ring vacuum pumps fouling place, place after 20-30 minutes, use 10-12% hydrochloric acid solution soakage water ring vacuum pumps fouling place again, place after 60-90 minutes, adopt the pressurized air of 0.8-1MPa to purge Nash hytor fouling 10-15 minutes, then Nash hytor is placed 20-30 minutes; Start jetting machine, pressure is adjusted to 8-10MPa, aim at fouling place with cleaning machine gun head, step on the cleaning of kinetic pressure transmitter, clear up 5-10 minutes.Adopt technique scheme, can effectively remove Nash hytor fouling, due to just for fouling place, can not damage the pump housing like this, it can be widely used in the scale removal of Nash hytor.
Description
Technical field
The present invention relates to Calcium Carbonate Filtration machine Nash hytor fouling cleaning method.
Background technique
In the operation of first phase phosphogypsum ammonium sulfate device, due to Nash hytor serious scale, causing Calcium Carbonate Filtration operation to occur, degree of vacuum does not reach requires problem; And the method for traditional scale removal is for using acid soak, but easy etching apparatus during this method misoperation, causes unnecessary equipment damage, affects the working life of equipment.
Summary of the invention
For the deficiencies in the prior art part, the present invention aims to provide a kind of cleaning method of Nash hytor fouling, guarantees, in the process removing fouling, can not damage the pump housing.
The technical solution used in the present invention: a kind of cleaning method of Nash hytor fouling, comprises following operating procedure:
(1) Nash hytor is taken apart, adopt 8-10% hydrochloric acid solution soakage water ring vacuum pumps fouling place, place Nash hytor after 20-30 minutes, use 10-12% hydrochloric acid solution soakage water ring vacuum pumps fouling place again, place Nash hytor after 60-90 minutes, adopt the pressurized air of 0.8-1MPa to purge Nash hytor fouling 10-15 minutes, then Nash hytor is placed 20-30 minutes;
(2) start jetting machine, pressure is adjusted to 8-10MPa, aim at fouling place with cleaning machine gun head, step on the cleaning of kinetic pressure transmitter, clear up 5-10 minutes.
Adopt technique scheme, can effectively remove Nash hytor fouling, used by reality and show, removal effect is good, in removal process, although use hydrochloric acid solution to infiltrate, subsequent handling adopts high pressure water washing, can not leave over acid solution, and when infiltrating hydrochloric acid solution, just for fouling place, can not damage the pump housing like this, it can be widely used in the scale removal of Nash hytor.
Embodiment
A cleaning method for Nash hytor fouling, comprises following operating procedure:
(1) pump cover of the Nash hytor in a Calcium Carbonate Filtration operation is taken apart, take the cleaning eye of Nash hytor again apart, as the cleaning eye of rotatingshaft both sides, the cleaning eye that turnover gas is newly-increased, rubber ball, observe the foulant of pump inside, adopt 8% hydrochloric acid solution soakage water ring vacuum pumps fouling place, fouling place can be infiltrated with the cotton yarn soaking hydrochloric acid, place Nash hytor after 20 minutes, use 10% hydrochloric acid solution soakage water ring vacuum pumps fouling place again, fouling is under hydrochloric acid solution infiltrates has bubble to produce, placing ring vacuum pumps puts after 70 minutes, the pressurized air of 1MPa is adopted to purge Nash hytor fouling 10 minutes, then Nash hytor is placed 20 minutes, find that fouling part loosens,
(2) start jetting machine, pressure is adjusted to 10MPa, aim at fouling place with cleaning machine gun head, step on the cleaning of kinetic pressure transmitter, clear up 8 minutes, dirty block is under the active force of high pressure water, and dirty block fragmentation departs from, clear out outside pump by dirty block again, can complete cleaning, loading onto pump cover can use.
Claims (1)
1. a cleaning method for Nash hytor fouling, is characterized in that comprising following operating procedure:
(1) Nash hytor is taken apart, adopt cotton yarn soakage water ring vacuum pumps fouling place of immersion 8-10% hydrochloric acid solution, place Nash hytor after 20-30 minutes, use cotton yarn soakage water ring vacuum pumps fouling place of immersion 10-12% hydrochloric acid solution again, place Nash hytor after 60-90 minutes, adopt the pressurized air of 0.8-1MPa to purge Nash hytor fouling 10-15 minutes, then Nash hytor is placed 20-30 minutes;
(2) start jetting machine, pressure is adjusted to 8-10MPa, aim at fouling place with cleaning machine gun head, step on the cleaning of kinetic pressure transmitter, clear up 5-10 minutes.
