Abstract
The utility model relates to a pipeline antiseptic structure used for a residual oil system. The pipeline antiseptic structure used for the residual oil system comprises multiple stainless steel pipelines which are connected with one another. Antiseptic liners are arranged on the inner walls of the stainless steel pipelines. All the stainless steel pipelines are connected through flanges. Antiseptic liners are arranged on end faces of the flanges. The antiseptic liners are made of HDPE materials. Compared with the prior art, the pipeline antiseptic structure used for the residual oil system has the advantages of being good in antiseptic effect, long in service life and the like.
Description
Technical field
The utility model relates to a kind of residual oil system, especially relates to a kind of pipeline corrosion protection structure for the residual oil system.
Background technique
In the technology of anthraquinone preparation hydrogen peroxide; be that the solution of main solute is the carrier that the hydrogenation oxygenation carries hydrogen peroxide simultaneously in the hydrogen peroxide production process with anthraquinone; the master operation of working solution by product is removed by the residual oil system; because residual oil has very strong acidity; so the pipeline of the aqueous phase stream warp that separates at residual oil and residual oil is very easy to be corroded, and occurs because the leakage of the residual oil that sour corrosion causes through regular meeting.
The model utility content
The purpose of this utility model is exactly to provide a kind of in order to overcome the defective that above-mentioned prior art exists and can effectively prevent corrosive pipeline, improve the pipeline residual oil system pipeline anticorrosion structure in working life.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pipeline corrosion protection structure for the residual oil system comprises a plurality of interconnective stainless steel pipeline, and described stainless steel pipeline inwall is provided with corrosion-proof lining.
Connect by flange between each stainless steel pipeline, the end face of described flange is provided with corrosion-proof lining.
Described corrosion-proof lining is the liner of HDPE material.
Compared with prior art, the utility model is provided with corrosion-proof lining at the inwall of pipeline and the end face of flange, can avoid liquid in pipe directly to contact with stainless steel pipeline, and this corrosion-proof lining can adopt the HDPE material, this material is very strong to the corrosion resistance of acidity, can effectively improve working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of pipeline corrosion protection structure for the residual oil system comprises a plurality of interconnective stainless steel pipeline, connects by flange between these stainless steel pipeline.In order to improve the antiseptic property of pipeline, at the end face of stainless steel pipeline 1 inwall and flange 2 corrosion-proof lining 3 is set, make liquid in pipe directly to contact with stainless steel pipeline, thus the corrosion of avoiding, concrete structure is as shown in Figure 1.In the present embodiment, this corrosion-proof lining adopts the HDPE material, and this material is very strong to the corrosion resistance of acidity, can effectively improve working life.
Claims (3)
1. a pipeline corrosion protection structure that is used for the residual oil system comprises a plurality of interconnective stainless steel pipeline, it is characterized in that described stainless steel pipeline inwall is provided with corrosion-proof lining.
2. a kind of pipeline corrosion protection structure for the residual oil system according to claim 1 is characterized in that, connects by flange between each stainless steel pipeline, and the end face of described flange is provided with corrosion-proof lining.
