Abstract
In the present invention, nitrogen can be extracted for industrial purpose first by utilizing temperature difference of liquid nitrogen boiling point of -196 deg.C and liquid oxygen boiling point of -183 deg.C in the air and then liquid oxygen in to be stored in cylinder or tank by giving 150 atomspheric pressure on it after air is compressed to be liquid state by solar energy generation or normal industrial liquid air is applied; or liquid air is directly stored and transported and then nitrogen and oxygen is recovered separately when it is to be used by only utilizing simple releasing and recovering devices attached to places where refrigerating is required; refrigerating function can be realized by using liquid oxygen and liquid air to release oxygen or nitrogen at very low temperature.
Description
Continuous development along with human society, in industrial and agricultural production and daily life, need to come the ice making refrigeration with a large amount of refrigeration facilities, as larger freezer and ice plant or refrigerating chamber, refrigerator car, ship and the refrigerator of popularizing gradually in the whole world, the refrigerating plant of refrigerator-freezer and air conditioner etc., none is not to use the energy to make industrial refrigeration machinery and use electric energy to drive these mechanical devices and come ice making in a large number, refrigeration, therefore no matter refrigerating industry or its refrigerating machine, all will expend the energy in a large number, and refrigeration facility in the past also to use the harmful substances such as freon of destroying earth's ozone layer in a large number; Though refrigerating industry in the present age is progressively eliminated, but its not having a negative impact to human ecological environment is also cannot say for sure in the use of other industrial material, particularly the spent a large amount of energy of refrigerating industry add various resources, still be to use fossil energies such as coal combustion and oil mostly, a part is taken from water power, small part is taken from nuclear energy, obtaining mostly of these energy has great harm to human ecological environment, as the fossil energy that burns removes the mankind and will face outside the energy shortage crisis, and the global greenhouse effect that it causes and various harmful pollution are extremely difficult controls; And also there is very big risk in the use of nuclear energy; Even the renewable and clean energy resource hydroelectric generation, but its construction investment is excessive, and might cause multiple harm to rivers, cause some infringements to environment.
For this reason, I am on the basis of " utilizing the technical measures of solar energy on a large scale " and " utilizing the new technology of solar energy composting, system oxygen " these two invention technology of invention, and invention again " utilizes liquid air to replace the new technology of industrial refrigeration ".
The main contents of this invention: except that utilizing general industry compressed liquid air technology, after simultaneously utilizing solar electrical energy generation that air is compressed into liquid state on a large scale, utilize the boiling point that accounts for 78% liquid nitrogen in the air to be-196 ℃, and liquid oxygen is-183 ℃ the temperature difference, the principle that liquid nitrogen is evaporated in the liquid air earlier, divide two kinds of methods to use: 1. to use (composting and other use) to do industry, will be left oxygen and under 150 atmospheric pressures, be stored to and use in oxygen cylinder, jar, the case for extracting its nitrogen earlier; 2. do not get nitrogen earlier, be about to be compressed into liquid air and be stored in bottle, jar or the big case, being transported to needs with the area use.Then not needing with large-scale refrigerating industry is that freezer, ice plant, refrigerating chamber, car, ship and refrigerator, cabinet and air conditioner etc. are made refrigerating industry machinery, only needing to make the simple device that discharges liquid oxygen or air is installed in freezer, ice plant, refrigerating chamber, car, ship and refrigerator, cabinet and the air conditioner that needs refrigeration, when utilizing liquid oxygen or liquid air to discharge, the function of a large amount of heat absorptions and generation extremely low temperature, the refrigeration of freezer, ice plant etc. can be caused, and its refrigerating machine (also discharging oxygen or fresh air simultaneously) can be replaced fully to regulate air; Discharging devices such as absorption, storage oxygen are installed on liquid oxygen or the air assembly simultaneously, then recyclable a large amount of nitrogen, oxygen and other valuable gases also obtain valuable industrial nitrogen and oxygen when receiving refrigerating function, really get twice the result with half the effort.
Therefore this invention technology is that novelty is created, technical is again that reality is feasible, and use general industry compressed liquid air and use the solar energy not to the utmost and the air inexhaustible, that use of cleaning to replace the refrigerating industry that expends a large amount of energy, beyond measure the real social effect of the environmental protection that it is great and economic worth then are!
Claims (3)
1, after invention is used general industry compressed liquid air and utilized solar electrical energy generation to come the compressed liquid air on a large scale, use liquid air or liquid oxygen to replace the method for industrial refrigeration with refrigeration respectively.
2, according to claim 1 described for invented utilize compressed air to become liquid state after, extract earlier nitrogen and make industrial purposes and re-use liquid oxygen and reclaim the method for oxygen simultaneously to realize refrigeration.
3, according to claim 1 described for invented utilize compressed air to become liquid state after, utilize liquid oxygen or liquid air to replace the method that industrial refrigeration reclaims nitrogen, oxygen simultaneously fully.
