Description

Technical Field

[0001] This application belongs to the field of gas-liquid separation technology, and specifically relates to a gas-liquid separator for the production of p-chlorophenylglycine. Background Technology

[0002] Gas-liquid separators can be used for gas-liquid separation, gas phase demisting after condensers at the top of distillation towers, and gas phase demisting in various gas washing towers, absorption towers, and desorption towers. Gas-liquid separators can also be applied to various industrial and civilian applications such as gas dust removal, oil-water separation, and liquid impurity removal, including gas-liquid separation in the production of p-chlorophenylglycine. However, gas-liquid separators currently available for p-chlorophenylglycine production still have various shortcomings and cannot meet the needs of actual production.

[0003] As attached Figure 6 As shown, our company's original patented separator (201920680744.0) has a vertically arranged water collection plate inside the box, which has the disadvantage of a small water collection area, resulting in a small amount of liquid in the exhaust gas, which means that the separation is not thorough. At the same time, since the separation plate is only fixed at one end, it is easy to fall off after a long time. Therefore, we need an improved gas-liquid separator for the production of p-chlorophenylglycine. Utility Model Content

[0004] The purpose of this invention is to provide a gas-liquid separator for the production of p-chlorophenylglycine, which can increase the water collection area within the same volume of the separation tank, resulting in cleaner waste gas after separation, and at the same time, the separation plate is not easy to fall off.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas-liquid separator for producing p-chlorophenylglycine includes a housing for gas-liquid separation and a separation plate inclinedly disposed within the housing for collecting liquid from a gas-liquid mixture. The separation plate includes a first separation plate, a second separation plate, and a third separation plate arranged sequentially at intervals within the housing. The first, second, and third separation plates are all corrugated plates.

[0007] Furthermore, the housing is a closed cavity formed by a bottom plate, a top plate, and four side plates; a filter plate is provided between the top plate and the bottom plate; the cavity below the filter plate is used for temporary storage of the separated liquid.

[0008] Furthermore, the first separation plate, the second separation plate, and the third separation plate are fixed between the filter plate and the top plate.

[0009] Furthermore, the first separation plate is provided with an air vent at the end where it is fixed to the filter plate; the second separation plate is also provided with an air vent at the end where it is fixed to the top plate; and the third separation plate has the same structure as the first separation plate.

[0010] The angle between the separation plate and the vertical direction is b, and b is not less than 15 degrees.

[0011] Furthermore, the side panel of the housing above the filter plate is provided with a mixed gas inlet pipe, which is close to the first separation plate; and the side panel opposite to the mixed gas inlet pipe is provided with an outlet pipe.

[0012] Furthermore, a liquid level indicator and a drain valve are provided on the housing located below the filter plate.

[0013] Furthermore, the surface of the separator plate that comes into contact with the mixed gas is provided with a hydrophilic rubber layer; the rubber layer is silicone.

[0014] Compared with the prior art, the significant beneficial effects achieved by this application are as follows:

[0015] The inclined corrugated separation plate can effectively increase the water collection area, allowing the moisture in the mixed gas to be fully collected and preventing the exhaust gas from containing moisture.

[0016] The hydrophilic rubber layer can fully absorb the moisture in the gas mixture, allowing the water to collect and flow down the surface of the separator plate through the sieve plate into the bottom of the chamber.

[0017] With the liquid level indicator and drain valve installed, when the liquid level indicator detects that there is too much liquid in the tank, the drain valve can be opened to drain the liquid, thus preventing the liquid in the tank from being carried away by the exhaust gas and causing incomplete separation.

[0029] Example 1

[0030] like Figure 1-5 As shown,

[0031] A gas-liquid separator for producing p-chlorophenylglycine includes a housing 1 for gas-liquid separation, such as... Figure 1 As shown, the housing 1 is a closed cavity formed by a bottom plate, a top plate, and four side plates; a filter plate 14 is provided between the top plate and the bottom plate; the filter plate 14 divides the cavity into upper and lower parts, and the lower part of the cavity is used to temporarily store the separated liquid. The filter plate 14 is provided with a mesh for leakage (not shown in the figure, but common knowledge) to facilitate the collection of liquid flowing into the lower cavity; the filter plate 14 is fixed to the cavity by spot welding.

[0032] The housing 1 is equipped with an inclined separation plate, which is used to collect the liquid in the gas-liquid mixture;

[0033] like Figure 1 As shown, the separation plate includes a first separation plate 11, a second separation plate 12, and a third separation plate 13 arranged sequentially at intervals within the housing 1; the first separation plate 11, the second separation plate 12, and the third separation plate 13 are all corrugated plates. The separation plate is inclined, which increases the water collection area of ​​the separation plate, allowing more moisture to be collected from the mixed gas and preventing moisture from being carried in the discharged exhaust gas;

[0034] The corrugated separation plate can increase the collection area. Calculations show that when the corrugated separation plate is unfolded into a plane, its length is four times that of the original plate. This means that the water collection area is increased by about four times, which allows the moisture in the mixed gas to be fully retained on the surface of the separation plate.

[0035] The detailed structure is that the first separation plate 11, the second separation plate 12 and the third separation plate 13 are fixed between the filter plate 14 and the top plate. The fixing method is spot welding, which is convenient and quick.

[0036] like Figure 2-3 As shown, the first separation plate 11 is fixed to the filter plate 14 at one end with a vent 111; the second separation plate 12 is also fixed to the top plate at one end with a vent 111; and the third separation plate 13 has the same structure as the first separation plate 11. The mixed gas passes through the mixed gas inlet pipe 2 through the vent 111 of the first separation plate 11, the vent 111 of the second separation plate 12, and the vent 111 of the third separation plate 13, and finally, the relatively pure gas is discharged through the exhaust port (exhaust pipe 3).

[0037] like Figure 4 As shown, the angle between the separation plate and the vertical direction is b, and b is not less than 15 degrees. The more inclined the separation plate is, the longer the separation plate will be, which means the larger the water collection area will be. However, since the volume of the tank 1 is fixed, the larger the angle b is, the fewer the number of separation plates will be, making it difficult to arrange them. After repeated experiments, we finally adopted 15 degrees, which can ensure the water collection effect and also allow for more separation plates to be installed.

[0038] The side panel of the housing 1 above the filter plate 14 is provided with a mixed gas inlet pipe 2, which is close to the first separation plate 11; the side panel opposite to the mixed gas inlet pipe 2 is provided with an outlet pipe 3.

[0039] Work process,

[0040] When gas-liquid separation is required in the waste gas containing liquid generated during the production of p-chlorophenylglycine, the mixed gas enters the separation chamber 1 through the mixed gas inlet pipe 2. The mixed gas comes into contact with the surfaces of the first separation plate 11, the second separation plate 12 and the third separation plate 13 in sequence. The liquid flows down into the lower cavity after contacting the surface, and the pure waste gas is discharged through the outlet pipe 3.

[0041] Example 2

[0042] The structure of this embodiment is largely the same as that of Embodiment 1.

[0043] The difference is that,

[0044] like Figure 1As shown, a liquid level indicator 6 and a drain valve 4 are installed on the housing 1 located below the filter plate 14. A controller is also provided, and the controller is signal-connected to the liquid level indicator 6 and the drain valve 4. The liquid level indicator transmits the measured liquid level information to the controller. The liquid level indicator 6 uses a magnetic flip-plate liquid level gauge manufactured by Shanghai Sipai Company, which, in conjunction with a remote transmitter, transmits the liquid level signal to the controller for remote display and control, facilitating monitoring by operators in the control room.

[0045] There are two liquid level indicators 6. One is located below and close to the filter plate 14; the other is located above and close to the drain valve 4. When the upper liquid level indicator 6 detects a liquid signal, the controller sends an open signal to the drain valve 4 to automatically drain the liquid. When the lower liquid level indicator 6 detects no liquid signal, the controller sends a close signal to the drain valve 4. This allows for automatic operation.

[0046] The controller is a Siemens micro PLC controller, which is stable in quality and reliable in operation.

[0047] Example 3

[0048] The structure of this embodiment is largely the same as that of embodiment 2.

[0049] The difference is that,

[0050] like Figure 5 As shown, the two surfaces of the first separation plate 11 are provided with rubber layers 112; the rubber layers 112 can be firmly bonded to the surface of the first separation plate 11 by vulcanization; the surfaces of the second separation plate 12 and the third separation plate 13 are also provided with rubber layers;

[0051] The hydrophilic rubber layer 112 allows water to be retained through the adhesive layer of the separation plate, accelerating the accumulation of water.

[0052] Currently, the technical solution of this application has undergone pilot testing, which is a small-scale experiment before the product is mass-produced. After the pilot testing was completed, a user survey was conducted on a small scale, and the survey results showed that user satisfaction was high. Now, preparations have begun for the formal production and industrialization of the product (including intellectual property risk warning surveys).
