Abstract
The utility model relates to a hydrogenation purification nitrogen generation and deoxygenization tower which comprises a mixer and a deoxygenization tower, wherein the mixer is arranged inside the deoxygenization tower; an air inlet of the mixer extends outside the deoxygenization tower; the mixer is fixedly connected with the deoxygenization tower in a sealing manner; a through hole I is formed in the tube wall at the top of the mixer; and an inner chamber of the mixer is communicated with an inner chamber of the deoxygenization tower through the through hole I. According to the hydrogenation purification nitrogen generation and deoxygenization tower, the conventional separately-designed mixing tower and the deoxygenization tower are organically combined together, so that the mixing effect of hydrogen and nitrogen is relatively good, the reaction is relatively complete, the hydrogen use amount is reduced, the occupied space is small, and the investment cost is reduced.
Description
Technical field
The utility model relates to a kind of hydrogenation purifying nitrogen oxygen-removing tower processed.
Background technology
Oxygen-removing tower is one of equipment main in the hydrogenation purification process purification nitrogen, and oxygen-removing tower mainly is divided into two parts, the one, and hydrogen and nitrogen mixing section, the 2nd, catalyst reaction section.Have the structure of oxygen-removing tower now as shown in Figure 1, each label represents respectively among the figure: 1, blender; 2, oxygen-removing tower; 3, wireway.Blender 1 is communicated with oxygen-removing tower 2 by wireway 3.
The existing oxygen-removing tower course of work is: hydrogen at first enters blender with general nitrogen to be mixed, enter oxygen-removing tower by wireway 3 again, under catalyst action, oxygen reaction remaining in hydrogen and the general nitrogen generates water, remove most of oxygen remaining in the general nitrogen, obtained highly purified nitrogen.
The defective of prior art is: hydrogen and the mixed effect of general nitrogen in blender are undesirable, it is incomplete to enter the oxygen-removing tower internal reaction, if reach highly purified nitrogen, needs to increase the use amount of hydrogen, and existing equipment that floor space is set is larger, thereby increased cost of investment.
The utility model content
According to above deficiency of the prior art, technical problem to be solved in the utility model is: provide a kind of hydrogenation purifying nitrogen oxygen-removing tower processed, can improve mixed effect, reduce the hydrogen use amount, reduce cost; Reduce occupation area of equipment, reduce cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hydrogenation purifying nitrogen oxygen-removing tower processed, comprise blender and oxygen-removing tower, comprise blender and oxygen-removing tower, blender is arranged at oxygen-removing tower inside, and the air inlet of blender extends the oxygen-removing tower outside, blender and oxygen-removing tower are sealedly and fixedly connected, and blender top is provided with the through hole I, and the through hole I is communicated with mixer cavity with the oxygen-removing tower inner chamber.
Wherein:
Described blender comprises air inlet pipe and mixing tube, air inlet pipe is arranged in the mixing tube, and mixing tube is positioned at oxygen-removing tower, and the air inlet pipe upper end extends oxygen-removing tower and mixing tube is outside, the air inlet pipe lower end is provided with the through hole II, and the through hole II is communicated with the air inlet pipe inner chamber with the mixing tube inner chamber.
Described venthole is positioned at the oxygen-removing tower bottom.
The course of work of the present utility model is: hydrogen at first enters air inlet pipe with general nitrogen tentatively to be mixed, mixed gas enters the mixing tube inner chamber by the through hole II on the tube wall of air inlet pipe bottom, under the effect of pressure, mist upwards flows along the mixing tube inner chamber, gas has obtained further mixing in this process, the mist that flow to the mixing tube top this moment enters oxygen-removing tower inner chamber top by the through hole I, catalyst is housed in the oxygen-removing tower, this moment, mist began contact catalyst, enter in the back under the pressure-acting of gas, mist is from the oxygen-removing tower top to flows, catalyst in the abundant contact oxygen-removing tower also reacts, and the gas that obtains after the reaction is discharged from the gas outlet of oxygen-removing tower bottom.
The utility model organically combines original respectively mixing column, the oxygen-removing tower of design, so that hydrogen and nitrogen mixed effect are better, reacts more complete, reduced the hydrogen use amount, and floor space is less, reduces cost of investment.

Fig. 2 is structural representation of the present utility model.
Among Fig. 2: 1, air inlet pipe; 2, mixing tube; 3, oxygen-removing tower; 4, through hole I; 5, through hole II; 6, gas outlet.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Hydrogenation purifying described in the utility model nitrogen oxygen-removing tower processed, comprise blender and oxygen-removing tower, blender is arranged at oxygen-removing tower 3 inside, and the air inlet of blender extends oxygen-removing tower 3 outsides, blender and oxygen-removing tower 3 are sealedly and fixedly connected, blender top tube wall is provided with through hole I 4, and the through hole I is communicated with mixer cavity with oxygen-removing tower 3 inner chambers.Wherein, blender comprises air inlet pipe 1 and mixing tube 2, air inlet pipe 1 is arranged in the mixing tube 2, mixing tube 2 is positioned at oxygen-removing tower 3, air inlet pipe 2 upper ends extend oxygen-removing tower 3 and mixing tube 2 outsides, air inlet pipe 1 bottom tube wall is provided with through hole II 5, and through hole II 5 is communicated with air inlet pipe 1 inner chamber with mixing tube 2 inner chambers, and gas outlet 6 is arranged at oxygen-removing tower 3 bottoms.
Hydrogen at first enters air inlet pipe 1 with general nitrogen tentatively to be mixed, mixed gas enters mixing tube 2 inner chambers by the through hole II 5 on the air inlet pipe 1 bottom tube wall, under the effect of pressure, mist upwards flows along mixing tube 2 inner chambers, gas has obtained further mixing in this process, the mist that flow to mixing tube 2 tops this moment enters oxygen-removing tower 3 inner chamber tops by through hole I 4, in the oxygen-removing tower 3 catalyst is housed, this moment, mist began contact catalyst, enter in the back under the pressure-acting of gas, mist is from oxygen-removing tower 3 tops to flows, catalyst in the abundant contact oxygen-removing tower 3 also reacts, and the gas that obtains after the reaction is discharged from the gas outlet 6 of oxygen-removing tower 3 bottoms.
