Embodiment
Below, with reference to drawings and Examples, the portable corrosion test platform of one of the present invention is described in detail.
As shown in Fig. 1 ~ 2, a kind of portable corrosion test platform, comprise dolly 1, dolly 1 arranges multiple reaction vessel 2, on dolly 1, welding supports water inlet pipe 3, the support 6 of rising pipe 4 and pipeline 5, water inlet pipe 3 is connected with constant temperature water tank 7 respectively with rising pipe 4, gas-holder 8 manually vacuum valve 9 is connected with one end of pipeline 5, tail gas recycle tank 10, refrigerated container 11, vacuum pump group 12 is connected respectively by the other end of Manual vacuum valve 9 with pipeline 5, water jacket 14 is welded outside the cylindrical shell 13 of reaction vessel 2, the water inlet tap 15 of water jacket 14 bottom connects water inlet pipe 3, the faucet 16 on water jacket 14 top connects rising pipe 4, shell flange 17 is formed at the top of reaction vessel 2, the protruding 18a that upper cover flange 18 is formed and the groove 17a that shell flange 17 is formed is tightly connected by rubber blanket 19, the top of upper cover flange 18 arranges joint 20, blind plate 21, DN3 valve seat 22, joint 20 is by metal hose 23, Manual vacuum valve 9 is connected with pipeline 5, tensimeter 24 is connected on DN3 valve seat 22.
Described reaction vessel 2 is five.
Described upper cover flange 18 forms No. I through hole 18b, and shell flange 17 forms No. II through hole 17b, and No. I through hole 18b is connected by bolt, nut with No. II through hole 17b.
Reaction vessel 2 is fixed on the base plate of dolly 1 by foot screw, owing to placing material to be corroded in reaction vessel 2, therefore need first to carry out Passivation Treatment to the surface of reaction vessel 2 before test, water inlet tap 15 is by controlling the water temperature of water inlet, control the temperature in reaction vessel 2, ensure that treat corrosion material and actuating medium react needed for temperature.
Pipeline 5 and metal hose 23 are for being communicated with the gas circuit between gas-holder 8, reaction vessel 2, tail gas recycle tank 10.
Manual vacuum valve 9 is communicated with gas circuit for Trimmed sums, two Manual vacuum valves 9 are all housed before each reaction vessel 2, to ensure be communicated with or block reaction vessel 2 and the gas circuit between gas-holder 8 and tail gas recycle tank 10, the corrosion condition treating corrosion material in reaction vessel 2 can be reflected, simultaneously two pass valve also can block the gas circuit between each reaction vessel 2, avoids reaction vessel 2 cross reactions and ensure that filling separately material between each reaction vessel 2, taking out material.
