According to the invention, the defects of the conventional flowmeter cleaning mode are overcome, effective cleaning of the miniature float flowmeter is achieved by means of a chemistry and physics combination mode, cleaning operation is convenient, the cleaning efficiency is improved, that the float is jammed is avoided, and the service life of the flowmeter is prolonged.
Description
Technical field
The present invention relates to a kind of Fouling Cleaning method of small-size glass pipe suspended body flowmeter.
Background technology
Suspended body flowmeter is lifted with changes in flow rate in vertical taper glass tube with float, the volume flow instrument for changing the circulation area between them to measure.When glass tube suspended body flowmeter is applied in flue gas monitoring system, due to containing dust, SO in flue gas2, the unwanted corrosion gas such as NO, flue gas can cause corrosion contamination after flowmeter, after Long-Time Service flowmeter float will be stuck and cannot normally show flow.
Chinese patent application CN102107195A discloses a kind of method for carrying out on-line cleaning to suspended body flowmeter, suspended body flowmeter is installed in recirculating cooling water system and is installed wash-out valve by it, hydroblasting is carried out into flowmeter using giant by the cooperation of cooling water and wash-out valve, so as to realize the on-line cleaning of flowmeter.But the suspended body flowmeter in flue gas monitoring system is small-sized, it is impossible to connect recirculating cooling water system, cause flowmeter cleaning difficult, reduce the service life of flowmeter.
The content of the invention
The technical problem to be solved is to provide a kind of Fouling Cleaning method of small-size glass pipe suspended body flowmeter, this method overcomes the defect of conventional flow meters cleaning way, effective cleaning of small-sized suspended body flowmeter is realized by the way of chemically and physically combining, and washing and cleaning operation is convenient, improve cleaning efficiency, avoid float stuck, extend the service life of flowmeter.
To solve above-mentioned technical problem, the Fouling Cleaning method of small-size glass pipe suspended body flowmeter of the present invention comprises the steps：
Step one, the dilute hydrochloric acid solution 250ml of preparation 5～7% are poured in glass beaker, beaker is put into into supersonic wave cleaning machine, small-size glass pipe suspended body flowmeter is positioned in glass beaker and is immersed in dilute hydrochloric acid solution, the heating-up temperature of supersonic wave cleaning machine be set to 30 ± 5 DEG C, scavenging period be set to 2 hours, then start cleaning；
Step 2, after two hours by small-size glass pipe suspended body flowmeter take out, appearance is rinsed well with clear water, NaOH solution 250ml for preparing 4～6% is poured in glass beaker, beaker is put into into supersonic wave cleaning machine, small-size glass pipe suspended body flowmeter is positioned in glass beaker and is immersed in NaOH solution and continues to clean 1 hour, and the heating-up temperature of supersonic wave cleaning machine is set to 40 ± 5 DEG C；
Step 3, after one hour by small-size glass pipe suspended body flowmeter take out, appearance is rinsed well with clear water, the pure water of 250ml is poured in glass beaker again, beaker is put into into supersonic wave cleaning machine, small-size glass pipe suspended body flowmeter is positioned in glass beaker and is immersed in pure water, starts supersonic wave cleaning machine and continues normal temperature cleaning half an hour；
Simultaneously submergence in the glass beaker of the analysis ethanol that small-size glass pipe suspended body flowmeter is moved into 99% concentration after the completion of step 4, pure water cleaning, continues normal temperature cleaning half an hour in supersonic wave cleaning machine；
Step 5, taking-up small-size glass pipe suspended body flowmeter, are dried up small-size glass pipe suspended body flowmeter using nitrogen.
Because the Fouling Cleaning method of small-size glass pipe suspended body flowmeter of the present invention employs above-mentioned technical proposal, i.e. this method is successively immersed in small-size glass pipe suspended body flowmeter in dilute hydrochloric acid solution, NaOH solution, pure water, the solution of analysis ethanol, pickling, alkali cleaning, washing and alcohol washes are carried out in supersonic wave cleaning machine, the temperature and time of each cleaning process is concurrently set, finally will be dried up using nitrogen after the taking-up of small-size glass pipe suspended body flowmeter.This method overcomes the defect of conventional flow meters cleaning way, and effective cleaning of small-sized suspended body flowmeter is realized by the way of chemically and physically combining, and washing and cleaning operation is convenient, improves cleaning efficiency, it is to avoid float is stuck, extends the service life of flowmeter.
Specific embodiment
The Fouling Cleaning method of small-size glass pipe suspended body flowmeter of the present invention comprises the steps：
