Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer, It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment, it is clear that described reality Applying example is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, It is practical new to belong to this for those skilled in the art's every other embodiment obtained without creative efforts The range of type protection.
As shown in Figure 1, liquids and gases are separated by gravity, are used for the present embodiment provides a kind of gas-liquid separation device Separate the gas in the liquid chemical reagents such as hydrochloric acid, sulfuric acid, potassium hydroxide, hydrogen peroxide, hydrofluoric acid or nitric acid.The device includes the One pipe and the second pipe 2, the second pipe 2 are plugged in the first pipe, and the first pipe is for passing through gravity for the gas in the liquid of injection point It separates out and, the second pipe 2 is used to isolate the liquid discharge after gas.
First pipe includes sequentially connected first pipeline section 14, the second pipeline section 15 and third pipeline section 16 from top to bottom, and second The outer diameter of pipeline section 15 is greater than the outer diameter of the first pipeline section 14 and the outer diameter of third pipeline section 16.First pipeline section 14, second of the present embodiment Pipeline section 15 and third pipeline section 16 are integrally molded so as the first pipe.First pipe is made of corrosion resistant soluble polytetrafluoroethylene material, Certainly, the material of first pipe of the utility model is not limited to the soluble poly tetrafluoroethene of the present embodiment, can also be by other Resistant material is made.
First pipe is equipped with the first inlet 11 and the first leakage fluid dram 12, and the first inlet 11 into the first pipe for conveying Impurity gas to be separated liquid, the first inlet 11 is located at the side of the first pipe, and the first inlet 11 is equipped with the second valve Door (being not shown).First leakage fluid dram 12 is used for the substance being discharged in the first pipe, generally after maintenance or use, uses It is discharged in by the liquid in the first pipe.Because the present apparatus is vertically-mounted, the first leakage fluid dram 12 is located at the bottom end of the first pipe, the first drain Pipe is equipped with third valve (being not shown), and in normal use, third valve is in close state, when needs stop making When with the gas-liquid separation device or needing repairing, third valve is opened, residual liquid in the first pipe and the second pipe 2 is discharged.
Exhaust outlet 13, and its top for being located at the first inlet 11 are additionally provided on first pipe, for will separate in the first pipe Gas discharge, since the density of gas is less than liquid, gas can float upwards, in order to which the gas isolated is discharged, exhaust The height of mouth 13 is higher than the height of the first inlet 11.Exhaust outlet 13 is equipped with the first valve (being not shown), works as needs When gas is discharged, the first valve is opened, the gas in the first pipe is discharged.
Gas-liquid separation device provided by the present embodiment further includes liquid level sensor and pressure sensing cell.Liquid level sensor In the first pipe, height is between the first inlet 11 and exhaust outlet 13, liquid level in the first pipe of real-time detection, When liquid level reaches at or above the height of exhaust outlet 13, the second valve is turned down or closed, reduces institute's impurity gas to be separated Liquid enter the flow of the first pipe, the liquid level in the first pipe reduces, and then is lower than the height of exhaust outlet 13, and liquid level is prevented to be higher than When exhaust outlet 13, opens the first valve and misprint out liquid.Pressure sensing cell is set to exhaust outlet 13, for detecting in the first pipe Air pressure judge whether to need to open the first valve by detected gas pressure value, when the air pressure in the first pipe reaches Setting value and 13 height of liquid level first row port, open the first valve.
Second pipe 2 is made of corrosion resistant soluble polytetrafluoroethylene material, certainly, second pipe 2 of the utility model Material is not limited to the soluble poly tetrafluoroethene of the present embodiment, can also be made of other resistant materials.Second pipe, 2 outer wall There are gap between the first inside pipe wall, and sealed set between the first pipe upper end and the second pipe 2.As shown in Fig. 2, for convenience The gas-liquid separation device cooperates other components to use, and the upper gap of the second pipe 2 and the first pipeline section 14 is arranged smaller.
As shown in figure 3, the lower ending opening of the second pipe 2 forms the second inlet 21, the second inlet 21 is located in the first pipe And be connected to the first pipe, the second inlet 21 is located at the top of above-mentioned first leakage fluid dram 12.In order to guarantee in the liquid after separation There is no gas residue, the lower end surface angle with horizontal plane of the second pipe 2 increases the liquid and of impurity gas less than 90 degree in this way The collision of two pipes 2, makes more gases be separated.According to a large amount of experiment it is found that lower end surface and the horizontal plane of the second pipe 2 When angle is 45 degree, the effect separated in gas from liquid is best.The top of second pipe 2 is additionally provided with the second leakage fluid dram 22, and second Leakage fluid dram 22 extends the other end of the first pipe, for that will separate the discharge of the liquid after gas.
When using the gas-liquid separation device, the second valve is opened, is sent the liquid of impurity gas by the first inlet 11 Enter the first pipe to be separated, since gas density is smaller than fluid density, when liquid turns to flow downward, gas will rise and gather For collection at the top of the first pipe, liquid enters the second pipe 2 from the bottom of the second pipe 2, and from 22 row of the second leakage fluid dram of the second pipe 2 Out, guarantee there is no gas residue in the liquid of discharge.
Liquid level in the first pipe of liquid level sensor real-time detection prevents liquid level to be higher than the height where liquid level sensor Degree, the pressure by pressure sensing cell real-time detection the first pipe internal pressure installed at exhaust outlet 13, in the first pipe Reach setting value, and when the liquid level inside the first pipe is lower than 13 height of exhaust outlet, the first valve is opened, and exhaust outlet 13 will The gas discharge isolated opens third valve, the first pipe of discharge and the second pipe 2 if gas-liquid separation device needs to safeguard Interior residual liquid.Gas-liquid separation device provided by the present embodiment, low manufacture cost, it is easy to use and without often maintenance, It is easy to separate the gas of doping in a liquid.
Note that above are only the preferred embodiment and institute's application technology principle of the utility model.Those skilled in the art's meeting Understand, the utility model is not limited to specific embodiment described here, is able to carry out for a person skilled in the art various bright Aobvious variation, readjustment and substitution is without departing from the protection scope of the utility model.Therefore, although passing through above embodiments The utility model is described in further detail, but the utility model is not limited only to above embodiments, is not departing from It can also include more other equivalent embodiments in the case that the utility model is conceived, and the scope of the utility model is by appended Scope of the claims determine.
