Description
Technical field
The utility model relates to metallurgical technical field of oxygen generation, relates in particular to a kind of oxygenerator purging, warming apparatus.
Background technology
Heating of oxygenerator is divided into the heating under gentle hot state that add under cold state.The object of heating under cold state is to make oxygen generating plant evenly be warmed up to normal temperature state from low-temperature condition, and blows down the obnoxious flavour impurity such as the water remain in equipment, carbonic acid gas, carries out maintenance and prepares.Heating under hot state is may bring moisture and the solid impurity in equipment into while blowing down maintenance, and equipment is kept dry, and for air separation facility starts, creates conditions.
In prior art, the heating method of oxygenerator is generally to adopt compressor operation to rotate the gas of heating, after air precooling system and molecular sieve purification, as the gas of heating, enters air separation facility, and air separation facility is heated.This heating means are effective, but prerequisite be air compressor machine during air separation facility is heated, need to move, and this process compressor operation do not produce direct economic benefit always, production cost is improved.With each 36 hours design warm-up times, calculate, 7400KW air compressor machine will consume 26.64 ten thousand degree electricity, with 0.56 yuan of calculating of every degree electricity, be roughly equal to 150,000 yuan of Renminbi, in metallurgical Production for oxygen, oxygenerator stops and the power consumption cost of heating in oxygenerator two stages of startup will reach 300,000 yuan like this.If 12000KW air compressor machine, the subnormal purging power consumption of heating of start-stop car one will reach 480,000 yuan.
Utility model content
In order to overcome prior art deficiency, the utility model provides a kind of oxygenerator purging, warming apparatus.The utility model is simple in structure, easy to operate, need not rotate by air compressor machine, can realize oxygenerator purging, the process of heating, and has reduced the energy consumption of this process, has improved the benefit of enterprise.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Oxygenerator purges, a warming apparatus, comprises the upper and lower tower of nitrogen storage device and air separation column, and nitrogen storage device is connected with tower under air separation column by the first pipeline, and under air separation column, tower is connected with tower on air separation column by second pipe.
Nitrogen enters tower under air separation column by the first pipeline, and tower under air separation column is purged, heated; Meanwhile, the nitrogen that enters tower under air separation column enters tower on air separation column by second pipe, and tower on air separation column is purged, heated.In the utility model, adopt nitrogen as the gas that oxygenerator is purged, heated, do not need the participation of air compressor machine, improved prior art scheme, save energy consumption.
Preferably, the first described pipeline is provided with heating unit.
Nitrogen under normal temperature state can be realized heating under the cold state of oxygenerator well, but can not be preferably for oxygenerator is carried out to heating of hot state.By add heating unit on the first pipeline, by heating unit, the nitrogen in the first pipeline is heated, nitrogen temperature is raise, like this, high temperature nitrogen just can finely meet the demand that the hot state of oxygenerator is heated.
Preferably, described nitrogen storage device is connected with tower under air separation column by the 3rd pipeline.
Adding the 3rd pipeline, is the efficiency that purges, heats in order to improve oxygenerator.
Preferably, the 3rd pipeline and the first pipeline are provided with interchanger.
At the cold state of oxygenerator, heat in process, in the first pipeline and the 3rd pipeline, simultaneously in tower under air separation column, pass into normal temperature nitrogen, hot state at oxygenerator is heated in process, heating unit on the first pipeline is opened, high temperature nitrogen in the first pipeline transfers heat to the 3rd ducted nitrogen by interchanger, its temperature is raise, do not adding under the low-cost prerequisite of heating unit, effectively reduced the hot state warm-up time of oxygenerator.
Preferably, the first pipeline is provided with the first valve, and second pipe is provided with the second valve, and the 3rd pipeline is provided with the 3rd valve.
The design of the first valve, the second valve and the 3rd valve, can regulate the nitrogen amount entering in the upper and lower tower of air separation column well, has guaranteed that the pressure-stabilisation in air separation column is at rational state, improves production security.
Compared with prior art, tool has the following advantages the utility model:
1) adopt nitrogen to replace in prior art and utilize the heated air of compressor operation gained as the gas that oxygenerator is purged, heated, greatly reduced energy consumption, reduced the production cost of enterprise;
2) pipeline in the utility model can adopt the pipeline of existing oxygen generating plant to design, without setting up specially new pipeline, and further production cost;
3) the utility model is simple in structure, easy to operate, when improving oxygenerator purging, heating effect, has reduced the energy consumption of this process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, nitrogen storage device 1 is connected with tower under air separation column 9 by the first pipeline 2, and under air separation column, tower 9 is connected with tower on air separation column 10 by second pipe 11, and the first pipeline 2 is provided with heating unit 4; Nitrogen storage device 1 is connected with tower under air separation column 9 by the 3rd pipeline 3, and the 3rd pipeline 3 and the first pipeline 2 are provided with interchanger 7; The first pipeline 2 is provided with the first valve 5, and second pipe 11 is provided with the second valve 8, the three pipelines 3 and is provided with the 3rd valve 6.
During the utility model work, the nitrogen of normal temperature state, from nitrogen storage device 1, under the adjusting of the first valve 5 and the 3rd valve 6, enters tower 9 under air separation column by the first pipeline 2 and the 3rd pipeline 3 respectively, and tower under air separation column 9 is purged, heated; Simultaneously, enter the nitrogen of tower 9 under air separation column by second pipe 11, and under the adjusting of the second valve 8, enter tower 10 on air separation column, tower on air separation column 10 is purged, heated, then nitrogen is discharged in tower vapor pipe 12 under tower vapor pipe 13 and air separation column respectively from air separation column, is collected the cold state that said process the is oxygenerator process of heating by nitrogen collection device 14.
The hot state process of heating of oxygenerator is:
