Description of the invention (,) Description of the invention The present invention relates to a method for evaporating liquid oxygen and its use in a method for producing gas by low-temperature fractionation of air. In the present application, gas means any mixture having a gas content higher than that of relative air, for example, at least 70S :, preferably at least 98¾. (In this application, all percentages are expressed as moles, unless explicitly indicated otherwise.) They specifically include impure gases, and industrial grade pure gases and high-purity gases with a purity of 99.99X or more. For many applications, it is necessary to convert the existing liquid oxygen into a tritium form by using a heat exchanger to evaporate the heat carrier in the main evaporator before use. This type of evaporation occurs especially when the gaseous gas is produced by cryogenic rectification, where the gaseous product occurs in a liquid state at the bottom of the distillation column, because it is less volatile than nitrogen and argon. In order to obtain the product in gaseous form from the refined column and to produce a rising vapor, the oxygen generated in the liquid state must be similarly evaporated in the main evaporator. The most popular here is the classical Linde double-column method, in which the main evaporator is located at the bottom of the low-pressure string and is operated with condensate from the top of the pressure string (see Tiefteaperat-111'16 (^ 11 by Hausen / Linde) 〖11 [Cryogenic Engineering], 2nd edition, section 4.1.2 on page 284). The main evaporator in this case is a condenser-evaporator operation and is often called the main condenser. It is also Implemented by one or more heat exchange zones that operate as a circulating or falling film evaporator. The invention also pertains to other two-column methods, for example, where the main evaporator is operated with air and has three or more Nitrogen-oxygen separation method ^ Customer I. The downstream of the nitrogen-gas separation rectification column can be connected to the other paper components to make this paper. The size of the paper applies to the Chinese National Standard (CNS) Α4 specification (210 × 297 mm) (Please read first (Notes on the back of this page are again on this page)-Assembling and ordering.

In order to remove some separated solids *, the entire equipment must be In large-scale air distribution equipment, for example, it means to stop working for two to five days. In order to reduce the accumulation of less volatile components, Xi's success has been achieved and autonomous evaporators have taken out some flushes. The liquid in the form of a stream, and the stream is lost. The less volatile components, together with the flushing volume, accumulate in the gas while maintaining the state of the liquid, making its splash in the main evaporator limited. In purified air decanting equipment, the flushing volume is customarily used to introduce evaporation The liquid oxygen content of the device is 0.02 to 0.04X. For the rectified air, it is high, because it uses a molecular sieve absorber instead of the previously used Revex or regenerator, which is less volatile due to its flammability The problem caused by the accumulation of components in this type of oxygen evaporator (main evaporator) has been reduced to the extent that this type of flushing flow is sufficient to prevent harmful concentrations of hydrocarbons without the need for additional capacity (see Tieftenperaturtechnik of Hausen / Linde [ Engineering], 2nd edition, section 4.5.1.5 on pages 312 and 313). The object of the present invention is to increase the availability of liquid oxygen from the main evaporator and, in particular, to prevent interruption of operation as much as possible. -4-This paper size is applicable to China Gujia standard (〇 阳) 8 4 specifications (2 丨 0 father 2-97 mm factory, ------ ^ ------------ order ( Please read the notes on the back before filling in this page) A7 B7 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperation Du V.

Invention Explanation (r) (Please read the notes on the back before ^^ € this page) Section 1 第 shows a part of the double-column used for low-temperature fractionation of air, that is, the top of the pressure column 1 and the low-pressure column 2 The bottom. The main evaporator 3 is used to evaporate the liquid flowing from the lowest mass transfer part of the low-pressure pipe column 2. The minimum mass transfer part of the gas is shown as plate 4 in the enclosure, but it can also be the filling of the arrangement). Take out the gaseous gas products from the low-pressure pipe string through line 9. The main evaporator can be located in a double-tube string-as shown in the first block, especially at the bottom of the low-pressure tube string. Alternatively, it may be provided as a separate component outside the double-column column or integrated into another tilted component separated from the double-column column, for example, methane is discharged into the column, as shown in DE4332870A1 or DE2055099A patent. Via the line 5 arranged in the lower plaque area of the main evaporator 3, the first flushing stream is taken out of the mine and introduced into the auxiliary evaporator 6. Tiller out, and the evaporated oxygen 8 returns to the low-pressure column. Alternatively, the vapor 8 may be sent from the low pressure string to the oxygen product line 9 or to another device, for example, the lower area of the methane decanting string according to DE4332870A1 or DE2055099 A patent. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the heat carrier 10 used for indirect heating of the main evaporator is nitrogen from the upper part of the power pipe column 1. The condensed nitrogen 11 in the main evaporator is used for refluxing in the two-column columns. The co-boiler evaporator 6 similarly uses nitrogen from a pressure pipe string or air as a heat carrier 12 and is heated in normal operation. The condensed heat carrier is removed via line 13 and fed into one or more rectification columns. At certain time intervals, for example, three to twelve months, preferably about six declining months, there is a switch from normal operation to heating operation by closing the valve 14 in the first flushing line 5. The feed to the heat carrier 12 is also closed. And this paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) S92Q59_b7_ V. 300K hot air of the invention description (&) through line 15 to the liquid separation chamber of the auxiliary rib evaporator 6 and the Media path 16 is removed again. The heating phase comprises closing, emptying, ripening, cooling and starting and holding, for example, 10 to 24 hours, preferably about 20 hours. It is advantageous if the first flushing stream 5 removes less volatile components by means of the device 19M before it is introduced into the ribbed evaporator 6, for example by adsorption, but it is not necessary in the context of the present invention. The second embodiment is different from the first embodiment in that the main evaporator is formed of multiple plaques 3a, 3b. For example, the plaques 3a, 3b are arranged concentrically in a central pipe as a gaseous nitrogen feed 10 from a pressure pipe string 1. Obviously, this example shows that "the embodiment can also be equipped with a device for removing less volatile components (1st to 19th). ——In nn I --- 1--—-II (Please read the notes on the back before filling this page) The paper size printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs applies the Chinese National Standard (CNS) A4 specification ( 210X297 mm; ί A7 B7 392059 V.
