Summary of the invention
The defective that the utility model exists at prior art, provide a kind of simple in structure, can before chemical cleaning, pass through simulated experiment in advance, cleaning performance, corrosion rate are estimated, thereby formulate the cleaning program of feasibility, and accurate test result chemical cleaning analogue experiment installation.
For solving the problems of the technologies described above, the technical solution of the utility model is: the chemical cleaning analogue experiment installation, comprise removable plate, and described removable plate is provided with the rinse bath that is used to hold cleaning fluid, is provided with liquid outlet and inlet on described rinse bath; The flowmeter that is used for metered flow; Be used for the scavenging pump with the extraction of the cleaning fluid in the described rinse bath, described scavenging pump is connected with the liquid outlet of rinse bath and the inlet end of flowmeter respectively by woven hose, and described woven hose is provided with operation valve; Be used to hold the testing tube of sample and test sample book corrosion rate and cleaning performance, described testing tube is connected with the endpiece of described flowmeter by connecting pipe, and the endpiece of described testing tube is connected with the inlet of described rinse bath.
As a kind of improvement, described testing tube is a plurality of, and described testing tube is a plexi-glass tubular.
As further improvement, described adjacent two plexi-glass tubulars are cascaded by connecting pipe.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: the sample that the utility model will need earlier to test is in use put into testing tube, by scavenging pump cleaning fluid is extracted out from rinse bath then, cleaning fluid arrives spinner-type flowmeter by woven hose, on woven hose, be provided with operation valve, may command is through the flow of spinner-type flowmeter cleaning fluid, cleaning fluid passes through the testing tube that is placed with sample after passing through spinner-type flowmeter successively then, be back in the rinse bath by connecting pipe more at last, cleaning fluid neutralizes in rinse bath, do not rest wash cycles, check that cleaning performance and extent of corrosion carry out the formal formulation and the modification of scheme after the period hour.Can in different testing tubes, put into the corrosion coupon of unlike material during use so that measure corrosion rate, and control dosing dosage flexibly according to the concentration of cleaning fluid, kept required concentration of lotion in this device, this device utilizes high time liquid of low feed liquor and high feed liquor to hang down back liquid, has satisfied the saturating capacity of cleaning fluid circulation time.The utility model is simple in structure, and test result is accurate, can pass through simulated experiment in advance before chemical cleaning, cleaning performance, corrosion rate are estimated, thus the cleaning program of formulation feasibility.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, the chemical cleaning analogue experiment installation comprises removable plate, and rinse bath 1, scavenging pump 2, flowmeter 3 and testing tube 4 are installed on removable plate.
Wherein, removable plate comprises base plate 5 and the mobile wheel 6 that is arranged on the base plate 5, and moving wheel 6 has four, small and exquisite so easy carrying.
On rinse bath 1, be provided with liquid outlet 7 and inlet 8, be used for holding cleaning fluid by rinse bath 1.
Scavenging pump 2 is connected with the liquid outlet 7 of rinse bath 1 and the inlet end of flowmeter 3 respectively by woven hose 9, cleaning fluid in the rinse bath 1 can be extracted out by scavenging pump 2, send into then in the flowmeter 3, on woven hose 9, be provided with operation valve 10, be used to control the flow of process spinner-type flowmeter cleaning fluid by operation valve 10.
Testing tube 4 is connected with the endpiece of flowmeter 3 by connecting pipe 12, and the endpiece of testing tube 4 passes through connecting pipe 12 and be connected with the inlet 8 of rinse bath 1, can be used for holding sample and the corrosion rate of test sample book and cleaning performance by testing tube 3.Wherein, testing tube 3 is a plexi-glass tubular, and testing tube 3 is a plurality of, as is set to four, and two adjacent plexi-glass tubulars by connecting pipe 12 series connection, can be put into several samples like this and tested.
Certainly, plexi-glass tubular can be changed different external diameter specifications as required at any time, can be by the rate of corrosion of different tube diameters specimen or test piece under same flow, also can be replaced with the glass tube of identical caliber, put into sample that is cleaned dirty sample and the test piece that different parts fetches respectively and do experiment, as seen effect more obvious, for easy to use, can valve all be set everywhere in this flow process.
Also be provided with sewage draining exit 11 on testing tube 3, the dirt after will cleaning by sewage draining exit 11 is discharged.
