Description
Technical field
The present invention relates to a kind of bearing tower type container of plastics corrosion protective lining, specifically be used to have the chemical industry equipment Corrosion resistant linings of pressure requirement, belong to chemical industry equipment and industrial antisepsis erosion technical field.
Background technology
The chemical anticorrosion tower includes the pressure operation requirement more.Even if the anticorrosion tower that normal pressure uses is also followed design, manufacturing and the checking and accepting technology index request of pressure vessel.Therefore, the manufacture anti-corrosion product, satisfying pressure design operation requirement is the primary condition of service of goods.
In prior art,, adopt stainless steel and noble metal manufacturing usually in order to satisfy the requirement of pressure vessel type anticorrosion tower.In order to reduce cost, also adopt the clad lining anticorrosion, promptly make pressure hull with the high strength carbon steel, bear mechanical stress, be lining (comprising composite metal plate) with corrosion resistant metal material.Adopt ptfe plastic as Corrosion resistant linings in the tower that also has.Above-mentioned two kinds of lining tower costs are too expensive.The medium osmosis corrosion is the universal phenomenon of anticorrosive, and plastic lining is because the plastic molecules result is made up of secondary bonding winding, and the result is loose, packing density is less, the space is bigger, is difficult to avoid producing pore etc. in the moulding, for medium osmosis and diffusion provide steric requirements.And under the pressure-bearing effect, the plastic lining layer slippage that may misplace, even crack or ftracture, the anticorrosion inefficacy of plastic lining layer caused.
And a large amount of more general in, the universal anticorrosion tower of low pressure, generally adopt nonmetallic materials lining (lining rubber, lining FRP, the lining silicates, comprise other various plastic lining anti-corrosion product), but tower internals (wire mesh demister, distributor, column plate, delete plate etc.) are because the restriction of manufacturing process also is to use stainless steel and noble metal to manufacture and design.Because cost performance is unreasonable, can not get reasonable production and configuration like this.Therefore reduce production costs, in satisfying, the supporting requirement of low pressure corrosion protection equipment, for a long time, by the user is pursued.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of bearing tower type container of plastics corrosion protective lining is provided, can improve the penetrating power of moulding lining density and plastic lining layer compressive resistance, satisfy the production steel lining and mould pressure-bearing tower and product requirement.
Main solution of the present invention is achieved in that
It is withstand voltage tower body that the present invention adopts connecting flange that the more piece carbon-steel parts is connected, and connect by skirt and to be anchored on the basic part, set gradually wire mesh demister, column plate, hold-down grid in withstand voltage tower body inside, delete plate, divide device and filler again, withstand voltage tower body barrel is established manhole outward respectively, hand hole, gas phase is imported and exported, the filtrate import, liquid-inlet and discharging opening, feature is at withstand voltage tower body inwall and manhole, hand hole, and gas phase is imported and exported, the filtrate import is provided with wire netting array architecture and rotation fast-open type structure respectively in liquid-inlet and the discharging opening.
Described wire netting array architecture is made up of reinforcement and metallic steel expanded metals and plastics lining, and reinforcement and metallic steel expanded metals are welded on the withstand voltage tower body, the plastics lining is coated on reinforcement and metal foil forms one on the net.
Described rotation fast-open type structure is made up of upper and lower gripper shoe and inner piece, and inner piece is arranged between upper backup pad and the lower supporting plate, and upper backup pad and lower supporting plate and the welding of withstand voltage tower body form one, form matching, by rotating the loading and unloading of coming soon.
Described plastic lining layer thickness scope is at 10～20mm.
Described internals plastic lining layer thickness range is at 4～10mm.
Compared with the prior art the present invention has the following advantages:
The present invention is relatively simple for structure, compact, reasonable, owing to be provided with the wire netting array architecture in tower body, constituted and has coordinated between metal structure and the plastic interface and the excessive lock room of control coupling; Adopt the wire netting array architecture to weld,, make pressure hull, network array architecture and plastics lining mould by revolving that the process heat repoussage is body formed to be combined as a whole again through plastics lining bag pressure in pressure hull.The tower body internals adopt rotation fast-open type structure, also adopt the plastics lining, and this is simple in structure, and easy construction is with low cost.The plastics lining is heated to press and has improved lining density, thereby has improved the impermeabilisation ability, has also improved the anti-stress intensity of plastics linings, has satisfied pressure-bearing/nonstandard tower type container plastics lining anticorrosion requirement.Anticorrosion ability is good, shock resistance, and Stability Analysis of Structures is reliable, has realized that high strength lining moulds requirement, and the production that is applied to the pressure vessel anti-corrosion product for the plastics lining provides engineering practice checking basis.Technology is simple, easy construction, and for the plastics lining is applied to the pressure vessel product, having overcome plastics lining and metal composite physical property can problem of disharmony.
