Abstract

The utility model relates to a dry absorption tower, which comprises an outer casing and at least two linings arranged on the surface of the outer casing. Because at least two linings are arranged on the surface of the outer casing of the novel absorption tower, namely arranging a double-layer lining 1 and a lining 2,and the joint of each lining plate of the double-layer lining 1 is in staggered distribution, on the basis of ensuring the thickness of the internal lining of the tower body is relatively thinner, and reducing the tower body weight, acid liquid in the tower body is guaranteed not to leak from the joints, corrosion resistant capacity of the tower body is increased, service life is prolonged, production safety and equipment reliability are significantly increased. The dry absorption tower has the advantages of simple structure and high corrosion resisting capacity, excellent social valve and economic valve, which is easy in popularization and application.

Description

A kind of dry absorption tower

Technical field

The utility model relates to a kind of dry absorption tower, belongs to chemical industry equipment.

Background technology

Dry absorption tower is a kind of imperative equipment in the relieving haperacidity industry.At present, the tower body of dry absorption tower all adopts outer cover of steel plate, has built one deck acid-proof ceramic tile in outer cover of steel plate by laying bricks or stones, and acid solution very easily leaks out to outer cover of steel plate from the mortar joint between the acid-proof ceramic tile like this, make outer cover of steel plate produce corrosion, cause outer cover of steel plate damaged and cause production accident.

The utility model content

The purpose of this utility model is to provide a kind of dry absorption tower, with avoid tower body by acid liquid corrosion, guaranteed the tower body quality.

To achieve these goals, the technical solution of the utility model has adopted a kind of dry absorption tower, comprises shell body, and shell inner surface is provided with two-layer lining at least outside.

Described shell body inner surface is provided with two-layer lining 1, also is provided with a lining 2 in the inboard of lining 1.

Described two-layer lining 1 is interspersed, the seam of two-layer lining 1 1/2-1/3 that interlaces.

Described lining 1 is anticorrosion asbestos board.

Described lining 2 is an acid-proof ceramic tile.

Because the shell body inner surface of the utility model dry absorption tower is provided with two-layer at least lining, be specially a two-layer lining 1 and a lining 2, seam between each liner plate of two-layer lining 1 is in staggered distribution mutually, thinner relatively at the thickness of having guaranteed the tower body inner liner, alleviated on the basis of tower body weight, guaranteed that the acid solution in the tower body can not revealed between the seam, increased the resistance to corrosion of tower body, prolong its service life, improved the security of production and the reliability of equipment greatly.The utility model is simple in structure, and antiseptic property is good, has favorable social and economic worth, is easy to apply.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, dry absorption tower of the present utility model comprises shell body 3, is provided with two-layer lining 1 at shell body 3 inner surfaces, also is provided with skim lining 2 in the inboard of lining 1, and wherein two-layer lining 1 is interspersed, and the seam 4 of two-layer lining 1 interlaces 1/3.Lining 1 in the present embodiment is anticorrosion asbestos board, and lining 2 is an acid-proof ceramic tile.

Tower body internal layer of the present utility model is before pasting lining; elder generation is with burr, the overlap sanding of flat of housing internal layer; carry out derusting by sandblasting; brushing concentration then is 20% the rare clay of KPI; dry solidification; do not return rust with the protection steel body surface; with concentration is that to paste lining 1 be anticorrosion asbestos board one deck to the rare clay of 30% KPI; behind the dry solidification; rare clay subsides lining 1 with same concentration is anticorrosion asbestos board one deck again; seam between each liner plate of two-layer lining 1 1/3h that interlaces, building at last again and going up lining 2 is acid-proof ceramic tile.
