I. Glass lined reactor technical specification performance

1. Permissible pressure (Mpa)

Note: the pressure inside the kettle varies according to the contract.

2. Permissible temperature: reaction vessel using temperature 0 ℃ to 200 ℃, storage vessel using temperature 0 ℃ to 150 ℃; equipment temperature resistance ≥ 200 ℃, cold shock: 110 ℃; thermal shock: 120 ℃. Glass-lined reactor heating and cooling should be carried out slowly.

3. thickness of glass-lined layer: the thickness of glass layer of glass-lined reactor is 0.8-2.0 mm (0.8-2.3 mm , VN>5000L); the thickness of glass of glass-lined reactor accessories is 0.6-2.0 mm.

4. Voltage resistance: glass lining has good insulating property, the thickness of glass layer is within the specified thickness, and the working surface is not electrically conductive when checking the glass layer with 20 KV high-frequency electric spark.

5. corrosion resistance: suitable for various concentrations of inorganic acids, organic acids, organic solvents and weak alkali corrosion (hydrofluoric acid, fluoride ion-containing media, temperature ≥ 180 ℃ concentrated phosphoric acid and strong alkali except).

6. Have a light and clean surface, easy to clean.

II. Glass lined reactor installation, use and maintenance

1. Before lifting, the surface of glass-lined reactor should be carefully checked for any damage to the porcelain surface, and rubber-soled shoes should be worn into the tank to avoid damaging the porcelain surface. Protect the porcelain surface with soft cushion such as rubber plate pad when lifting, and do not touch or collide with the porcelain surface. When handling unpacked equipment, only the lugs and supports of the reactor can be stressed. Do not allow the receiver, clamps and other vulnerable parts of the force, should not be rolled or pried with a crowbar.

2. when tightening the card, should be symmetrical tighten in turn, the force can not be tightened evenly, so as to avoid the local force is too large damage to the porcelain surface, in order to obtain a good seal, to the reactor tank slowly steam, to be softened by the pad and then tighten the card.

3. It is forbidden to weld directly on the outer wall of glass-lined reactor; when welding near the glass-lined reactor, the glass-lined reactor should be covered tightly to avoid electric welding.

When welding near the glass-lined reactor, the glass-lined tank should be covered tightly to avoid the welding slag splashing and burning the glass surface. 4.

4. All glass-lined parts of the seal, should be based on the reaction medium, temperature, selection of gasket materials (factory products are configured in accordance with the general conditions of the gasket).

5, when installing the stirrer, shaft sealing radial runout adjusted to *** small, to ensure sealing, and the stirrer can not be reversed, to avoid the stirrer falls, bruising the porcelain surface.

6 glass-lined reactor should not be used in the following media reaction and storage, otherwise it will be damaged faster due to corrosion.

(1) any concentration and temperature of hydrofluoric acid;

(2) PH ≥ 12 and temperature ≥ 100 ℃ of alkaline media;

(3) Phosphoric acid with a concentration of 30% or more and a temperature of ≥180℃;

(4) The reaction of alternating acid and alkali;

(5) Other media containing fluoride ions;

(6) Easy to adhere to the coking of the material.

7. The process of using should be slowly warming and cooling, because the stress produced by sudden heating and cooling will affect the service life of the glass-lined reactor and the porcelain reactor.

Because the stress caused by sudden heating and cooling will affect the service life of the glass-lined reactor and damage the porcelain surface. 8.

8. pay attention to the sealing condition of each flange connection, if leakage is found, measures should be taken, if acid is encountered, use alkali to neutralise and wash it quickly.

9. When entering the kettle for installation or overhauling, lay a soft cushion on the bottom of the kettle to avoid tools falling into the kettle, and wear rubber-soled shoes to avoid damaging the glass surface. If the outlet is blocked, don't use metal tools to shovel, use wooden stick or other soft objects to unblock. 10.

10, in the process of use should be regularly checked, such as in the material found in the glass lining debris, should be immediately inspected, found that there is a burst parts, should be dealt with in a timely manner.
