Abstract
The utility model provides a leakage-proof type rectifying tower section used for phosgene product production. The leakage-proof type rectifying tower section used for the phosgene product production comprises an inlet pipeline, an upper flange, an outlet pipeline, a lower flange and a pipeline pup joint, wherein the upper flange is arranged on the lower end portion of the inlet pipeline, and the lower flange is arranged on the upper end portion of the outlet pipeline. The upper flange is connected with the lower flange through a bolt, a spacer is arranged between the upper flange and the lower flange, the pipeline pup joint is arranged on the inner side of the pipe wall of the lower end of the inlet pipeline, the upper end portion of the pipeline pup joint is fixedly connected with the inner side of the pipe wall, the pipeline pup joint penetrates through the upper flange and the lower flange, and the lower end of the pipe pup joint is arranged in the outlet pipeline. The leakage-proof type rectifying tower section used for the phosgene product production has the advantages of being simple in structure, strong in practicality, good in sealing performance, strong in corrosion resistance and long in service life.
Description
Technical field
The utility model relates to a kind of pencil manufacturing equipment, specifically, has related to a kind of phosgene production and has saved with Drain Resistance formula rectifying tower.
Background technique
In the process of chemical industry phosgene production, the use of rectifying column is essential, the pipelines that adopt to the rectifying column transported material more at present, adopt flange to connect being connected between these pipelines, between pipeline and the rectifying column, traditional flange connects the sealing of selecting suitable pad to guarantee the joint more.But in chemical industry, the material of transportation often corrosivity is strong, easily causes the damage of flange connections pad, and then destroys the leakage that sealing that flange connects causes material, and these materials often toxicity are very strong, leak the after stain environment
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus a kind of simple in structure, practical, good airproof performance is provided, anti-corrosive properties are strong and the phosgene production of long service life with Drain Resistance formula rectifying tower joint.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of phosgene production saves with Drain Resistance formula rectifying tower, it comprises inlet pipeline, be arranged on the upper flange of described inlet pipeline underpart, outlet conduit, be arranged on lower flange and the pipeline short section of described outlet conduit upper end portion, wherein, described upper flange and described lower flange are bolted, described pipeline short section is arranged on the tube wall inboard of described inlet pipeline lower end, the upper end portion of described pipeline short section is fixedly connected with survey in the described tube wall, described pipeline short section passes described upper flange and described lower flange, and the lower end of described pipeline short section is arranged in the described outlet conduit.
Based on above-mentioned, described pipeline short section is the conical pipeline pipe nipple.
Based on above-mentioned, be provided with pad between described upper flange and the described lower flange.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model is connected obstructed with traditional flange, it increases pipeline short section, described pipeline short section is arranged between upper flange and the lower flange, connect inlet pipeline and outlet conduit by pipeline short section, material flows through described upper flange and described lower flange joint by pipeline short section, can not contact upper flange, lower flange and pad, and then avoid corrosion to pad, guarantee the sealing that upper flange is connected with lower flange, can increase the service life, can guarantee that again material can not reveal; It has simple in structure, practical, good airproof performance, anti-corrosive properties are strong and the advantage of long service life.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of phosgene production saves with Drain Resistance formula rectifying tower, it comprises inlet pipeline 1, be arranged on the upper flange 3 of described inlet pipeline 1 underpart, outlet conduit 2, be arranged on lower flange 4 and the pipeline short section 5 of described outlet conduit 2 upper end portions, wherein, described upper flange 3 is connected by bolt 6 with described lower flange 4, be provided with pad 7 between described upper flange 3 and the described lower flange 4, guarantee the sealing of joint, described pipeline short section 5 is arranged on interior survey of tube wall of described inlet pipeline 1 lower end, the upper end portion of described pipeline short section 5 is fixedly connected with described tube wall inboard, described pipeline short section 5 passes described upper flange 3 and described lower flange 4, and the lower end of described pipeline short section 5 is arranged in the described outlet conduit 2.
Based on above-mentioned, for material can pass through described pipeline short section 5 smoothly, described pipeline short section 5 is conical pipeline pipe nipples.
Based on above-mentioned, described conical pipeline pipe nipple is arranged between upper flange 3 and the lower flange 4, described conical pipeline pipe nipple connects inlet pipeline 1 and outlet conduit 2, material flows through described upper flange 3 and described lower flange 4 joints by the conical pipeline pipe nipple, can not contact upper flange 3, lower flange 4 and pad 7, and then avoids the corrosion to pad 7, guarantee that upper flange 3 is connected the sealing that connects with lower flange, can increase the service life, can guarantee that again material can not reveal, avoid polluting.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characteristics is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
