Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The underlying principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships that are based on those shown in the drawings, which are merely for convenience in describing the present invention and to simplify the description, and are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus the terms are not to be construed as limiting the invention.
It is understood that the terms "a" and "an" should be interpreted as meaning "at least one" or "one or more," i.e., that a quantity of one element may be one in one embodiment, while a quantity of another element may be plural in other embodiments, and the terms "a" and "an" should not be interpreted as limiting the quantity.
Referring to fig. 1 to 3, a pipeline blockage prevention nitrogen deoxo device according to a preferred embodiment of the present invention for removing oxygen and/or nitrogen contained in a chemical substance such as octafluorocyclobutane stored in at least one storage bottle 900 is described in detail below, and the storage bottle 900 has a filling port 9001. Preferably, the storage bottle 900 is implemented as a steel bottle.
It will be understood by those skilled in the art that the chemical is stored in the storage bottle 900 in a lower liquid state and an upper gaseous state due to evaporation. When the filling port 9001 is opened, the gas state of the chemical substance is exhausted from the filling port 9001.
The density of the chemical gas is greater than that of oxygen and greater than that of nitrogen, and when the storage bottle 900 is left standing for a long time, higher-concentration oxygen and/or nitrogen can be collected above the inner cavity of the storage bottle 900. However, when oxygen and/or nitrogen gas is continuously discharged, the oxygen and/or nitrogen gas and the chemical gas cannot achieve the layering effect as if they are left standing for a long time, and the layering is not obvious. Therefore, when oxygen and/or nitrogen gas in the inner cavity of the storage bottle 900 is discharged, a part of the chemical substances stored in the storage bottle 900 is discharged together. In other words, when the oxygen and/or nitrogen gas in the storage bottle 900 is discharged, a gas mixture of the oxygen and/or nitrogen gas and the chemical substance is actually discharged.
The device for removing oxygen and nitrogen capable of preventing pipeline blockage comprises at least one flow control assembly 10, wherein the flow control assembly 10 comprises a first flow measuring part 11 and at least one first control valve 12, the first flow measuring part 11 is connected with the filling port 9001 formed in the storage bottle 900 through a pipeline so as to enable the gas mixture to flow out through the filling port 9001, in the flowing out process, the discharge flow of the gas mixture is detected through the first flow measuring part 11, so that the discharge flow of the gas mixture is detected, and when the discharge flow of the gas mixture is detected to be overlarge, the discharge flow of the gas mixture is regulated through the first control valve 12, so that the situation that the chemical substances stored in the storage bottle 900 are all discharged and waste is caused due to the overlarge discharge flow of the gas mixture is avoided.
The first flow-measuring member 11 has an inlet 1101 and an outlet 1102, the inlet 1101 and the filling port 9001 of the storage bottle 900 communicate with each other, and the first control valve 12 is installed at the outlet 1102 of the first flow-measuring member 11 to control the degree of opening of the outlet 1102. It will be appreciated by those skilled in the art that when the outlet 1102 is opened to a greater degree, the flow of the gas mixture exiting the outlet 1102 is excessive; when the outlet 1102 is opened to a small degree, the discharge flow rate of the gas mixture from the outlet 1102 becomes small, thereby achieving the purpose of adjusting the discharge flow rate of the gas mixture.
Preferably, the first flow measuring element 11 is embodied to comprise a flow meter by means of which the discharge flow of the gas mixture is detected.
Preferably, the first control valve 12 is implemented to include a flow regulating valve, with which the degree to which the outlet 1102 is opened is controlled, thus adjusting the discharge flow rate of the gas mixture. Thus, when it is desired to discharge the gas mixture from the storage bottle 900, the first control valve 12 is opened, the gas mixture flows out along the filling port 9001, and then the gas mixture is discharged in the direction from the inlet 1101 to the outlet 1102 of the first flow measuring element 11. In addition, when the gas mixture is discharged, the magnitude of the flow rate of the gas mixture discharged is detected by the first flow measuring part 11, and when the first flow measuring part 11 detects that the flow rate of the gas mixture discharged is too large, the opening degree of the outlet 1102 is controlled by the first control valve 12, so that the flow rate of the gas mixture discharged from the outlet 1102 is reduced, so that the gas mixture is slowly discharged from the outlet 1102, thereby preventing the chemical substance stored in the storage bottle 900 from being discharged at one time due to the too large flow rate of the gas mixture when the gas mixture is directly and rapidly discharged from the filling port 9001, and preventing the chemical substance stored in the storage bottle 900 from being wasted.
Further, the deoxygen device capable of preventing pipeline blockage further comprises a constant temperature part 20, wherein the constant temperature part 20 is arranged on the storage bottle 900 and can be heated to heat the storage bottle 900, the storage bottle 900 is heated and then is kept warm, the temperature of the storage bottle 900 is kept constant, the relative volatility of oxygen and/or nitrogen in the storage bottle 900 is improved, the oxygen and/or nitrogen in the storage bottle 900 is enabled to be rapidly gathered above the storage bottle 900, the concentration of the oxygen and/or nitrogen gathered above the storage bottle 900 is improved, and the proportion of the oxygen and/or nitrogen in the discharged gas mixture is further improved. In other words, the discharge amount of oxygen and/or nitrogen can be increased.
Preferably, the constant temperature member 20 is implemented to include a heater blanket wrapping the lower body of the storage bottle 900 to heat the chemical substance in a liquid phase state inside the storage bottle 900.
It should be noted that, when the lower body of the storage bottle 900 is heated by the thermostatic element 20, the temperature of the upper body of the storage bottle 900 is lower than that of the lower body. Therefore, when the chemical gas mixture is discharged from the filling port 9001, the chemical gas is not discharged from the filling port 9001, and when the chemical gas mixture passes through the upper bottle body, the chemical gas is liquefied by cooling due to the low temperature of the upper bottle body, and then the amount of the chemical gas discharged is reduced, so that the waste of the chemical gas is reduced.
It will be appreciated by those skilled in the art that the storage bottle 900 cannot be completely filled when filling the chemical into the storage bottle 900. Thus, the chemical remains in a gaseous state where the storage bottle 900 is adjacent to the filling port 9001. In other words, when filling the chemical into the storage bottle 900, the chemical near the upper side in the storage bottle 900 is in a gas phase state, and the chemical near the lower side in the storage bottle 900 is in a liquid phase state. When the gas mixture contained in the chemical substance is removed, the gas mixture near the upper portion is discharged from the filling port 9001, and the concentration ratio of the gas phase and the liquid phase in the storage bottle 900 is a certain value during the discharge, so that oxygen and/or nitrogen is continuously precipitated from the liquid phase at the bottom, thereby improving the effect of removing oxygen and/or nitrogen.
Preferably, the thermostatic element 20 is arranged to maintain the temperature of the storage bottle 900 between 30 ℃ and 50 ℃.
Further, the device for removing oxygen and nitrogen capable of preventing pipeline blockage further comprises a control and pressing element 30, and the control and pressing element 30 is connected with the first control valve 12 through a pipeline. The control member 30 includes a vacuum generator 31, the vacuum generator 31 is connected to the first control valve 12 through a pipeline, so that after the first control valve 12 is opened, the gas mixture will continue to flow through the pipeline arranged between the vacuum generator 31 and the first control valve 12, and during the flow, the vacuum generator 31 adjusts the pressure in the pipeline connected between the vacuum generator 31 and the first control valve 12 to be in a balanced and stable negative pressure state, and reduces the pressure value in the pipeline. It will be understood by those skilled in the art that the smaller the pressure value of the gas mixture, the lower the liquefaction temperature of the gas mixture, and therefore the lower the liquefaction temperature of the gas mixture by reducing the pressure value in the pipeline after the gas mixture is discharged from the pipeline in order to avoid liquefaction of the chemical gases in the gas mixture. In this way, clogging due to liquefaction of the chemical gas in the gas mixture after the gas mixture is discharged from the pipeline is avoided.
In other words, when the heated gas mixture is discharged from the outlet 1102, since the subsequent pipeline is not heated, the temperature in the pipeline is lower than that in the storage bottle 900, and thus if the gas mixture is directly discharged from the outlet 1102, the chemical gas in the gas mixture is liquefied upon cooling. By setting the pressure control member 30, the pressure value in the pipeline is reduced, so that the liquefaction temperature of the chemical gas in the gas mixture entering the pipeline is reduced, and even if the temperature in the subsequent pipeline is lower than the temperature in the storage bottle 900, the chemical gas in the gas mixture is not liquefied, thereby avoiding the blockage of the pipeline in the process of discharging the gas mixture.
