Abstract
The utility model discloses an inlet connection manifold for an oxidation furnace with annual output of 300,000 tons of ammonia, which comprises a manifold main body. A row of holes are arranged on the horizontal position of the manifold main body; a throttling orifice connector is welded on each hole; a row of liquid pipes are arranged below the manifold main body; a flange flat cover is installed at the right end of the manifold main body; and a pipe connecting flange of transition section is installed at the left end of the manifold main body. The inlet connection manifold adopts reasonable structure and design; the row of holes and the throttling orifice connectors arranged on the manifold main body can be used for limiting the quantity of water entering each grouping pipe of the middle-section wall pipe, so as to control the heat absorption capacity in coil pipes at different positions; therefore, the heat absorption of the oxidation furnace can be optimized. The arranged flange flat cover can be disassembled for examining and cleaning the inner part of the manifold; and the arranged pipe connecting flange of transition section is used for connecting an external pipeline.
Description
Technical field
The import that the utility model relates to a kind of converter for ammonia oxidation connects header.
Background technology
Up to the present, single cover maximum productivity of domestic double pressurized method nitric acid plant oxidized still generally is the device of 500 tons of scales of daily output, promptly produce the device of 150,000 tons of nitric acid per year, but the device that 1000 tons of scales of daily output are also arranged, promptly produce the device of 300,000 tons of nitric acid per year, this also is the oxidized still that at present bigger in the world single cover nitric acid production plant is used.And the import of these equipment connection header all haves much room for improvement.
The utility model content
The technical problems to be solved in the utility model provides respectively the divide into groups import of coil pipe of a kind of stage casing wall pipe as the device of producing 300000 tons of nitric acid per year and connects header.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of import connection header that is used to produce per year 300,000 tons of converter for ammonia oxidations, comprise the header main body, the level attitude of described header main body is provided with a round, each Kong Shangjun is welded with the throttle orifice joint, the below of header main body is provided with a liquid discharge pipe, and the right-hand member of described header main body is equipped with the flange flat cover, and left end is equipped with a reducer pipe connecting flange.
As preferably, described header main body is made by the carbon element pipe.
Compared with prior art, the beneficial effects of the utility model are: reasonable in design, a round that is provided with on the header main body and throttle orifice joint, can be used for limiting the into interior water yield of each grouping pipe of stage casing wall pipe, control caloric receptivity in the different positions place coil pipe with this, thereby make the heat absorption of oxidized still reach optimizing.The flange flat cover that is provided with, but overhaul and cleaning header inside, the reducer pipe connecting flange of setting is used for being connected with external pipe.It mainly is to be used for respectively the divide into groups import of coil pipe of stage casing wall pipe to connect header that this import connects header, and it is better that its use properties connects header than existing import, can make the heat absorption of oxidized still reach optimizing more, has practicality more.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the sectional view of A-A line among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As depicted in figs. 1 and 2, a kind of import connection header that is used to produce per year 300,000 tons of converter for ammonia oxidations comprises header main body 1, and header main body 1 is made by the carbon element pipe.Be drilled with a round 2 on the level attitude of described header main body 1, all be welded with throttle orifice joint 3 on each hole 2, this throttle orifice joint 3 is used to limit the into interior water yield of each grouping pipe of stage casing wall pipe, control caloric receptivity in the different positions place coil pipe with this, thereby make the heat absorption of oxidized still reach optimizing.The below of described header main body 1 is provided with a liquid discharge pipe 4.The right-hand member of described header main body 1 is equipped with flange flat cover 5, but overhaul and cleaning header inside.The left end of header main body 1 is equipped with a reducer pipe connecting flange 6, is used for being connected with external pipe.
The foregoing description is a kind of preferred embodiment of the present utility model, for those skilled in the art person, all is apparent, straightaway.The development of other any similar type is all in protection domain of the present utility model.
