Description

Technical Field

[0002] Separation tanks are equipment used to separate mixtures into different components. They are widely used in chemical, pharmaceutical, food processing and other industries. They separate and purify materials by utilizing the differences in density, relative viscosity or chemical properties of materials. These equipment are usually made of stainless steel or other corrosion-resistant materials to ensure that they can handle a variety of chemicals or food safety requirements.

[0003] Separation tanks play an important role in industrial applications, especially for the separation of gas-liquid mixtures such as oil and gas commonly used in the petrochemical field. At present, most of the common separation tanks in the prior art adopt the principles of collision, interception and gravity separation to achieve the separation of gas-liquid mixtures. Although the separators arranged inside them can meet the basic separation requirements, the common separator structures often use baffle structures for gas-liquid separation, and the gaps or gaps in the baffle structures are prone to accumulate solid particles or adherent substances, which is not only not conducive to the circulation of gas-liquid mixtures, but also inconvenient to clean and replace. In addition, the arrangement of multiple baffles of the separator set with a baffle structure can extend the flow trajectory of the internal gas-liquid mixture and has a good separation effect, but it also extends the flow time of the internal gas-liquid mixture and reduces the separation efficiency. At the same time, the flow mode of the gas-liquid mixture through the baffles is also relatively scattered, and the separation effect is also relatively unsatisfactory. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1-3The present embodiment relates to a layered separation structure of a separation tank 100, comprising a separation tank 100 body, a separation chamber 1 is arranged at a feed inlet 101 on the separation tank 100 body, the separation chamber 1 is divided into a first cavity 111 and a second cavity 112 by a mounting frame 11 arranged therein, a ventilation pipe 113 is arranged on the mounting frame 11 and a plurality of separation cylinders 12 are arranged, the separation cylinder 12 is placed at the bottom of the first cavity 111 and passes through the second cavity 112 to reach the inner cavity of the separation tank 100 body, the feed inlet 101 is connected to the second cavity 112 and a guide groove 123 of an adapted size is opened at a corresponding position of the separation cylinder 12 in the second cavity 112, a liquid storage cylinder 2 is arranged at a corresponding position of the separation tank 100 body below the separation cylinder 12, a sand discharge port 21 is opened at the bottom of the liquid storage cylinder 2, and a liquid discharge port 22 is opened on the side, and an exhaust port 102 is also provided on the separation tank 100 body and is placed on one side of the separation chamber 1.

[0024] Specifically in this embodiment, see Figure 2 , the gas-liquid mixture can enter the second cavity 112 of the separation chamber 1 through the feed port 101, and then the gas-liquid mixture can enter the interior of multiple separation cylinders 12 through the guide groove 123 on the separation cylinder 12, wherein the liquid mixture can directly flow into the cavity of the separation tank 100 through the separation cylinder 12 and reach the lower liquid storage cylinder 2 for storage and deposition, and the gas in the gas-liquid mixture entering the separation cylinder 12 can move upward along the cylinder and enter the first cavity 111 of the upper separation chamber 1 through the top of the separation cylinder 12, and a certain amount of gas stored in the first cavity 111 can move downward along the ventilation pipe 113 provided on the mounting frame 11 and enter the cavity of the separation tank 100. The specific structure of the multiple separation cylinders 12 and the ventilation pipe 113 arranged on the mounting frame 11 in the separation chamber 1 can be referred to. Figure 3As shown, the gas reaching the cavity of the separation tank 100 continues to move along the cavity and reaches the exhaust port 102 on one side of the separation chamber 1 for discharge, and the impurities such as silt contained in the liquid mixture entering the liquid storage cylinder 2 through the separation cylinder 12 are deposited, and the silt and other impurities that have settled and accumulated to a certain amount can be discharged through the sand discharge port 21 at the bottom of the liquid storage cylinder 2. At the same time, the liquid stored in the liquid storage cylinder 2 and the cavity of the separation tank 100 to a certain extent can be discharged through the liquid discharge port 22 on the side of the liquid storage cylinder 2, thereby realizing the separation process of the gas-liquid mixture. The design of the separation structure in the separation tank 100 is compared with the traditional baffle structure. The multiple separation cylinders 12 arranged in the separation chamber 1 can facilitate the circulation and aggregation of the gas-liquid mixture, while ensuring a certain separation effect, the flow trajectory and flow time of the gas-liquid mixture inside the separation tank 100 are further shortened, and the setting of the separation cylinder 12 makes it difficult for impurities such as mud and sand contained in the liquid mixture therein to hang on the wall and accumulate during the flow process. In addition, the setting of the liquid storage cylinder 2 below the separation cylinder 12 can reduce the fluctuation amplitude and splashing phenomenon generated during the flow of the liquid mixture inside the cavity of the separation tank 100, thereby ensuring the fluidity and stability of the gas-liquid mixture during the separation process, thereby further improving the separation effect and separation efficiency.

[0025] The separation cylinder 12 is arranged in a funnel shape, with a closing opening 121 in the middle thereof and connected to a separation tube 122 arranged below the closing opening 121. The liquid mixture entering the separation cylinder 12 can first flow through the closing opening 121, and then enter the separation tube 122 below the closing opening 121 to reach the liquid storage cylinder 2 of the separation tank 100 below. The separation cylinder 12 arranged in a hopper shape and provided with the closing opening 121 can further control the flow rate of the liquid mixture in the separation cylinder 12, and play a certain buffering and gathering role, further reduce the fluctuation amplitude and splashing phenomenon of the liquid mixture falling into the liquid storage cylinder 2, further optimize the flow process of the liquid mixture and further improve the separation effect.

[0026] The guide groove 123 is also equipped with a filter screen 1231 of an appropriate size. The exhaust port 102 on the main body of the separation tank 100 is provided with a filter element 1021, and the discharge port 22 in the liquid storage cylinder 2 is provided with a baffle 221. The setting of the filter screen 1231 on the guide groove 123 can preliminarily filter the impurities with slightly larger volumes, such as block solids or large particles contained in the gas-liquid mixture, so as to avoid the phenomenon that the impurities enter the separation cylinder 12 and cause the separation cylinder 12 to be blocked, thereby affecting the separation effect and the separation process, and further improving the stability of the separation process. At the same time, the setting of the filter element 1021 at the exhaust port 102 can further filter and purify the gas and discharge it, thereby reducing the emission of harmful gases. The pollution to the environment and unnecessary harm to the human body are eliminated, and the filter element 1021 can separate the water vapor contained in the cavity of the separation tank 100 and the gas, so that it forms condensation beads on the filter element 1021 and then drips into the cavity of the separation tank 100, further improving the filtering effect and filtering stability of the gas. In addition, the setting of the baffle 221 at the discharge port 22 in the liquid storage cylinder 2 can effectively control the flow rate of the liquid discharged from the liquid storage cylinder 2, avoiding unnecessary fluctuations and splashing during discharge, and at the same time, reducing the fluctuation caused by a certain amount of impurities such as mud and sand deposited above the sand discharge port 21 at the bottom of the liquid storage cylinder 2 during the liquid discharge process, thereby further improving the purity and stability of the liquid discharge.

[0027] See also Figure 2 , a plurality of wind plates 3 are distributed in the cavity of the separation tank 100, and the wind plates 3 are staggeredly distributed in the cavity between the ventilation pipe 113 and the exhaust port 102. The setting of the corresponding positions of the wind plates 3 can further extend the gas flow path, and the gas entering the cavity of the separation tank 100 through the ventilation pipe 113 can further separate the liquid droplets entrained in the gas under the action of the wind plates 3, so that the gas flows into the cavity of the separation tank 100 through the wind plates 3 and is discharged through the liquid storage cylinder 2, and then the gas that has been dehydrated by the wind plates 3 is discharged after secondary filtration through the filter element 1021 at the exhaust port 102. The setting of the wind plates 3 can further enhance the efficiency of gas-liquid separation, and can effectively utilize the internal space of the cavity of the separation tank 100, further improving the separation effect and separation stability.

[0028] The main body of the separation tank 100 is also provided with an exhaust assembly 4, and the exhaust assembly 4 includes a fan 41 and an exhaust channel 42. The exhaust channel 42 is placed in the cavity of the main body of the separation tank 100 and is arranged toward the ventilation duct 113 in the separation chamber 1. The fan 41 is placed on one side of the separation chamber 1 and is connected to the exhaust channel 42 inside the cavity. During the separation process of the separation tank 100, the fan 41 on the main body of the separation tank 100 can blow through the exhaust channel 42 to the inside of the separation tank 100 cavity and along the exhaust duct direction, so that the separation tank 100 cavity The gas in the body reaches the exhaust port 102 along the wind plate 3. The exhaust component 4 can further improve the fluidity of the gas in the cavity of the separation tank 100 and the accuracy of the flow direction, reduce the long-term accumulation and residual phenomenon of gas in the cavity of the separation tank 100, thereby further improving the separation effect and separation efficiency. In addition, the exhaust component 4 can further reduce the internal temperature of the cavity of the separation tank 100, reduce unnecessary influence on the gas-liquid mixture and the separation process caused by the excessively high or low internal temperature of the cavity of the separation tank 100, and improve the stability and efficiency of the separation process.

[0029] The separation tank 100 body is connected with a liquid level gauge 5, one end of which is connected to the inside of the liquid storage cylinder 2 and is flush with the installation position of the liquid discharge port 22 on the side of the liquid storage cylinder 2, and the other end is connected to the internal cavity of the separation tank 100 body and is installed and fixed at a position between the bottom of the separation cylinder 12 and the top of the liquid storage cylinder 2. The specific installation position of the liquid level gauge 5 can be as follows: Figure 4 As shown in , the liquid level height measured by the liquid level meter 5 can be seen in Figure 2 The setting of the liquid level meter 5 can control the content of the liquid mixture in the cavity of the separation tank 100, and control its liquid level below the bottom of the separation cylinder 12, so that the highest liquid level of the liquid mixture is lower than the bottom of the separation cylinder 12 and there is a certain interval between the bottom of the separation cylinder 12, thereby ensuring the stability and efficiency of the discharge of the liquid mixture in the separation cylinder 12. At the same time, under the control of the liquid level meter 5, this type of separation tank 100 can easily judge the specific content of the liquid mixture between the discharge port 22 inside the cavity and the bottom of the separation cylinder 12, which is convenient for observation and adjustment, and discharge through the discharge port 22 to ensure the liquid level stability and separation effect of the liquid mixture inside the cavity of the separation tank 100.

[0030] like Figure 2As shown in, the exhaust channel 42 includes a first exhaust channel 421 and a second exhaust channel 422. The first exhaust channel 421 is also connected to the fan 41 and is placed above the liquid level measured by the liquid level gauge 5. The second exhaust channel 422 is connected to the first exhaust channel 421 and is arranged between the bottom of the separation cylinder 12 and the top of the liquid storage cylinder 2, passing through the main cavity of the separation tank 100 to reach below the exhaust port 102, and extending upward along the exhaust port 102 to a position above the liquid level measured by the liquid level gauge 5. The fan 41 can be operated to purge along the ventilation pipe 113 through the first exhaust channel 421 and can be blown to the separation tank 100 through the second exhaust channel 422. The exhaust port 102 on the main body is purged. On the one hand, the second exhaust channel 422 can reduce the long-term accumulation and residue of gas at the exhaust port 102 in the cavity of the separation tank 100, thereby improving the separation effect and discharge efficiency of the gas. On the other hand, the position of the second exhaust channel 422 in the cavity of the separation tank 100 is set so that it is placed within the liquid level range measured by the liquid level meter 5, thereby further reducing the temperature of the liquid mixture in the cavity of the separation tank 100, increasing the distribution range and effect of the exhaust channel 42 in the cavity of the separation tank 100, so that the internal temperature of the cavity of the separation tank 100 is more effectively controlled and a certain control time is shortened, thereby further improving the stability during the separation process.

[0031] A guide frame 6 composed of a plurality of air ducts 61 is rotatably provided on the pipeline corresponding to the second exhaust channel 422 placed below the separation cylinder 12. The guide frame 6 is placed above the liquid storage cylinder 2 and is installed in the cavity of the separation tank 100 by means of supports 62 provided on both sides. A wind cap 4221 is also rotatably provided at the second exhaust port 102 on the second exhaust channel 422 located below the exhaust port 102. On the one hand, the adaptation structure of the guide frame 6 can further increase the contact area and effect with the liquid mixture through the plurality of air ducts 61 provided thereon. On the other hand, at the initial stage of the separation process of the separation tank 100, that is, when the liquid level of the liquid mixture contained in the cavity of the separation tank 100 is lower than the installation height of the guide frame 6, the guide frame 6 rotatably provided on the second exhaust channel 422 can be discharged to a certain extent during the discharge of the liquid mixture in the upper separation cylinder 12. The rotation of the wind cap 4221 can further guide and buffer the liquid mixture, increase the contact area and disturbance process with the liquid mixture, and at the same time, the supports 62 on both sides of the guide frame 6 can also play a certain supporting role for the second exhaust channel 422, thereby improving the stability during use. In addition, the wind cap 4221 rotatably arranged at the second exhaust port 102 on the second exhaust channel 422 can be appropriately rotated during the exhaust process of the second exhaust channel 422, so that the rotation of the wind cap 4221 can disturb and purge the gas contained in the cavity at the position of the exhaust port 102 of the separation tank 100, thereby further improving the fluidity and discharge efficiency of the gas, and the setting of the wind cap 4221 at the second exhaust port 102 can also prevent the liquid dripping at the upper exhaust port 102 from entering the second exhaust duct and causing an adverse effect on the second exhaust duct during the rotation.

[0032] A pressure gauge 103 and a safety valve 104 are also provided on the main body of the separation tank 100. The pressure gauge 103 and the safety valve 104 are placed on one side of the separation chamber 1. The pressure gauge 103 can detect the internal pressure of the separation tank 100 cavity in real time, and cooperate with the safety valve 104 to release the pressure to prevent the separation tank 100 from being damaged or dangerous due to excessive internal pressure during the separation process, thereby ensuring the stability and safety of the equipment during operation.

[0033] The main body of the separation tank 100 is also provided with a plurality of manholes 105, and the manholes 105 are arranged at corresponding positions at both ends of the separation tank 100 and in the middle of the cavity. The main body of the separation tank 100 placed on one side of the liquid storage cylinder 2 is also provided with a second liquid discharge port 106. The arrangement of the plurality of manholes 105 at corresponding positions of the main body of the separation tank 100 can facilitate the operator to inspect, clean and maintain the separation tank 100, thereby improving the flexibility and convenience of operation. At the same time, the arrangement of the second liquid discharge port 106 can quickly discharge the liquid mixture in the cavity of the separation tank 100 according to the use requirements, thereby meeting different use requirements and improving applicability and practicality.
