Abstract
The utility model discloses a high-pressure reaction vessel. The reaction vessel wall of the high-pressure reaction vessel is a multilayer vessel wall consisting of a base layer and a stainless steel layer. A connecting pipe and a sealing flange are arranged on the reaction vessel, and are fixedly connected through a bolt and a nut. A stainless steel liner in clearance fit with the internal diameter of the connecting pipe is arranged in the connecting pipe. An overlaying ring groove is formed on the inner wall of the end part of the connecting pipe. A stainless steel welding layer is overlaid between the overlaying ring groove and the stainless steel liner. The end face of the stainless steel liner and the stainless steel welding layer form the sealed end face of the connecting pipe. The high-pressure reaction vessel is simple in structure, high in corrosion resistance and long in service life.
Description
Technical field
The utility model relates to a kind of pressure vessel, especially a kind of high-pressure reaction vessel.
Background technology
High-pressure reaction vessel such as agitated reactor, hydrotreater wall thickness is bigger, and the reaction medium in this type high-pressure reaction vessel generally has stronger corrosivity, when reaction vessel designs; To adopt the stronger stainless steel of corrosion resistance with the reaction medium contact-making surface, still, because the wall thickness of high-pressure reactor is bigger; Use stainless steel as material of main part fully, production cost is higher, therefore; The lamination layer structure of some high-pressure reaction vessel walls employing explosive clad plates or liner plate, lining, its multiple layer, liner plate are selected stainless steel for use, and basic unit adopts carbon steel and low-alloy steel; When the bigger adapter of this high-pressure reaction vessel such as manhole are made, earlier with sealing surface with the built-up welding of stainless steel wlding, after the sealing surface machined; Assembly welding lining again, lining adopts matched in clearance with taking over internal diameter, and the assembling back is with angle welding soldering and sealing.Because the high-pressure reaction vessel long-term work is under alternate load; Lining can lose efficacy because of heavily stressed load with the angle welding of taking over soldering and sealing prematurely; Crackle appears; Cause Korrosionsmedium to pass through crackle and contact, the basic unit that makes bearing pressure because of the corrosion reduced thickness, is influenced the safe handling of container with basic unit.
The utility model content
The technical problem that utility model will solve: a kind of high-pressure reaction vessel is provided, and this high-pressure reaction vessel is simple in structure, corrosion resistance and good, long service life.
The technical scheme that the technical solution problem is taked: a kind of high-pressure reaction vessel; The composite bed chamber wall of reactor vessel wall for constituting by basic unit and stainless steel layer; On reaction vessel, be provided with and take over and sealing flange; Adapter and sealing flange are fastenedly connected through bolt, nut, in taking over, are provided with and take over the stainless steel lining of internal diameter matched in clearance, on the inwall of taking over the end, are provided with the built-up welding annular groove; Built-up welding stainless steel layer between built-up welding annular groove and stainless steel lining, stainless steel lining end face and stainless steel layer constitute the adapter seal face jointly.
Improvement as the utility model: between adapter seal face and sealing flange, be provided with the red copper seal washer.
Further improvement as the utility model: on the built-up welding annular groove of taking over the end inwall, be provided with groove.
Beneficial effect: the high-pressure reaction vessel of the utility model; Owing to adopted the composite bed chamber wall of reactor vessel wall for constituting of said high-pressure reaction vessel by basic unit and stainless steel layer; On reaction vessel, be provided with and take over and sealing flange, adapter and sealing flange are fastenedly connected through bolt, nut, in taking over, are provided with and take over the stainless steel lining of internal diameter matched in clearance; On the inwall of taking over the end, be provided with the built-up welding annular groove; Built-up welding stainless steel layer between built-up welding annular groove and stainless steel lining, stainless steel lining end face and stainless steel layer constitute the technical scheme of taking over seal face jointly, and the built-up welding annular groove has concurrently with stainless steel layer between the stainless steel lining and is connected and the corrosion-resistant effect; Make the drawback that the high-pressure reaction vessel of the utility model has avoided adapter of the prior art to be connected with stainless steel lining angle welding; The high-pressure reaction vessel of the utility model is simple in structure, corrosion resistance and good, long service life; Owing to adopted the technical characterictic that between seal face and sealing flange, is provided with the red copper seal washer, improved the sealing effectiveness of flange, make the high-pressure reaction vessel work of the utility model more stable, reliable, safety; Owing to adopted the technical characterictic that on the built-up welding annular groove of taking over the end inwall, is provided with groove, make the welding of taking over more firm with the stainless steel lining, prolonged the service life of high-pressure reaction vessel.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the high-pressure reaction vessel sealing flange of the utility model and the syndeton sketch map of adapter;
Fig. 2 is the high-pressure reaction vessel sealing flange of prior art and the syndeton sketch map of adapter.
The specific embodiment
As shown in Figure 1; The composite bed chamber wall of the high-pressure reaction vessel reactor vessel wall of the utility model for being made up of basic unit and stainless steel layer is provided with adapter 8 and sealing flange 3 on reaction vessel, adapter and sealing flange are fastenedly connected through bolt 2, nut 1; In taking over, be provided with and take over the stainless steel lining 9 of internal diameter matched in clearance; On the inwall of taking over the end, be provided with built-up welding annular groove 4, on the built-up welding annular groove of taking over the end inwall, be provided with groove 7, built-up welding stainless steel layer 5 between built-up welding annular groove and stainless steel lining; Stainless steel lining end face and stainless steel layer constitute the adapter seal face jointly, between adapter seal face and sealing flange, are provided with red copper seal washer 6.
As shown in Figure 2, the adapter seal face during the high-pressure reaction vessel of prior art is close only constitutes by taking over the stainless steel layer 5 of going up built-up welding, adapter 8 and the welding of stainless steel lining 9 angle weldings, and weld seam 10 is exposed in the high-pressure reaction vessel.
