Abstract
The invention discloses a storage process of finished products of fatty acid, which has the innovation points that after being put in a storage tank of the fatty acid, the finished products of the fatty acid are subjected to two-stage sealing protection of nitrogen seal and water seal, wherein the pressure of the nitrogen seal is slightly more than or equal to the atmospheric pressure. The storage process has the advantages that the air is insolated by the introduction of nitrogen to prevent the stored products from being oxidized. The invention also discloses special nitrogen-sealed equipment for realizing the storage process of the finished products of the fatty acid; a nitrogen machine, a nitrogen storage tank and a nitrogen tundish of the equipment are communicated with one another through pipelines; and the equipment is provided with a pressure control device connected with a PLC so as to realize the nitrogen seal and ensure the safety. In order to further improve the storage process of the finished products of the fatty acid, the invention also provides water-sealed equipment which provides a pipeline extending out of the storage tank of the fatty acid and entering an open water storage tank so as to realize the water seal and provide one channel additionally for the redundant nitrogen.
Description
Technical field
The invention provides a kind of storage process of finished products of fatty acid, be specifically related to a kind of air seal of using, reduce the storage process of finished products of fatty acid of oxygenation efficiency; The present invention also provides and has been special nitrogen-sealed, the water-sealed equipment of this process matching.
Background technology
Aliphatic acid has partial oxygen and changes into lower fatty acid, aldehyde etc. owing to the more high reason of drop temperature in process of production during preservation, cause product design to descend to some extent.By analysis, recognize that temperature and oxidation have the relation of how much multiples, and oxidation rate and oxygen concentration be directly proportional also, and daylight also there is certain relation to oxidation.
Summary of the invention
Main task of the present invention is to provide a kind of storage process of finished products of fatty acid, is specifically related to a kind ofly carry out two-stage sealing with air seal and water-stop, reaches to make the non-oxidizing purpose of product; For this reason, the present invention also provide this technology special-purpose nitrogen envelope, water-sealed equipment.
In order to solve above technical matters, a kind of storage process of finished products of fatty acid of the present invention, its innovative point is: after described finished products of fatty acid enters storage tank, it is carried out nitrogen envelope and water seal two-stage seal protection; Wherein, the pressure of nitrogen envelope is slightly larger than or equals bar pressure.
The present invention also provides a kind of special nitrogen-sealed equipment of realizing storage process of finished products of fatty acid, constitute by nitrogen machine, nitrogen storage jar and nitrogen intermediate tank, its nitrogen machine, nitrogen storage jar and nitrogen intermediate tank are communicated with by pipeline, on the pipeline between nitrogen storage jar and the nitrogen intermediate tank, be provided with reducing valve and nitrogen replenishment valve, be provided with at the top of nitrogen intermediate tank and let out the nitrogen valve; All be connected between above-mentioned nitrogen machine, nitrogen storage jar, nitrogen intermediate tank and the valve with PLC.
The present invention also provides a kind of special-purpose water-sealed equipment of realizing storage process of finished products of fatty acid, lets out nitrogen pipe formation for inserting in the uncovered water tank.
The invention has the advantages that: adopt above special-purpose water-tight equipment, make this technology reach the purpose that aliphatic acid is preserved in sealing, completely cut off air, prevented the oxidation of product; And in guaranteeing the product antioxidation process, adopt of the adjusting of PLC control presssure valve to the pressure of nitrogen pot and product jar, reach good safety performance, make this technology accomplished under safe environment, the personal safety that has promptly guaranteed operating personal is simultaneously by the storage quality that has guaranteed product.
Description of drawings
Figure is a structural representation of the present invention.
The specific embodiment
The nitrogen envelope that this technology adopted and the structure of water-sealed equipment are communicated as one by pipeline 6 between nitrogen machine 1, nitrogen storage jar 2, nitrogen intermediate tank 3, aliphatic acid holding vessel 4 and the uncovered water sealed tank 5 as shown in Figure 1.In order to make nitrogen gas pressure controlled, on the pipeline 6 between nitrogen storage tank 2 and the nitrogen intermediate tank 3, establish reducing valve 7 and nitrogen replenishment valve 8, and above nitrogen intermediate tank 3, establish and let out nitrogen valve 9, and with nitrogen machine 1, nitrogen storage jar 2, nitrogen intermediate tank 3, aliphatic acid holding vessel 4, reducing valve 7 and nitrogen replenishment valve 8 with let out nitrogen valve 9 and all be connected with PLC10, by the PLC setup pressure value, reach low nitrogen, the pressure height of replenishing of pressure, let out nitrogen, keep the purpose of safe pressure.
In the present invention, the internal pressure of nitrogen storage jar 4 is controlled at 0.5Mpa, and the pressure inverting of measuring by PLC10 is controlled the startup of nitrogen machine 1, and promptly the internal pressure of nitrogen storage jar 4 is controlled at less than 0.5Mpa, and nitrogen machine 1 starts; Otherwise close.When the nitrogen in the nitrogen storage jar 2 is delivered to aliphatic acid storage tank 4 through piping 6, will be to the pressure in its nitrogen storage jar 2 by reducing valve 7 adjustment of reducing pressure, pressure is 0.1Mpa when making its nitrogen arrive nitrogen intermediate tank 3, the nitrogen replenishment valve 8 of fine setting effect has been installed simultaneously, acting as of this valve replenishes nitrogen when pressure is not enough, make pressure remain on 10Kpa, for greater safety, let out nitrogen valve 9 in the installation of the top of aliphatic acid holding vessel 4, and aliphatic acid storage tank 4 is connected with uncovered water sealed tank 5 with a pipeline, the potential safety hazard of this equipment is eliminated in the equilibrium that keep-ups pressure.
Utilize the nitrogen envelope and the water-sealed equipment of above-mentioned special use, the finished products of fatty acid storage of this technology is just more convenient, and concrete steps are: after aliphatic acid enters aliphatic acid holding vessel 4, by nitrogen machine 1 pressurization pressure be the nitrogen of 10Kpa to aliphatic acid holding vessel 4, realize the nitrogen envelope.Because the nitrogen envelope has certain pressure, in order to prevent hypertonia to set off an explosion, except the depressurization of above-mentioned reducing valve 7 and the nitrogen effect of letting out of letting out nitrogen valve 9, also establishing a pipeline in aliphatic acid holding vessel 4 is inserted in the uncovered water sealed tank 5, unnecessary nitrogen is come in the water, simultaneously because the effect of inner and outer air pressure, uncovered water sealed tank 5 not only works to discharge unnecessary nitrogen, it is according to the pressure dependence inside and outside the pipeline, water has wherein also carried out water seal to aliphatic acid holding vessel 4, has realized two-stage leak free effect, makes the product secluding air, can't form oxidation, guarantee the storage quality.
