[0002] Dimethylcyclohexylamine, molecular formula: C8H17N, CAS number: 98-94-2; Dimethylcyclohexylamine is mainly used in the polyurethane catalyst industry. It is a low-viscosity, medium-active amine catalyst. It is a colorless, transparent, oily liquid with an amine odor. The product is a colorless liquid with a density of 0.849 g / cm3, a freezing point of less than -77°C, a boiling point of 159°C, and a flash point (open cup) of 43.33°C.

[0003] N,N-dimethylcyclohexylamine catalyst is a strong base with a distinctive amine odor. Its color darkens with extended use, but this does not affect its chemical activity.

[0021] Preferably, the side wall edges of the first sieve frame and the second sieve frame are respectively in close contact with the inner side wall of the separation tank.

[0022] The separation method of the gas-liquid separation device for the analytical treatment of dimethylcyclohexylamine comprises the following steps:

[0023] Step 1: Power on the equipment with the stable support of the base, connect the material conveying pipe to the feed pipe in the separation structure to convey the liquid, and connect the discharge pipe to the corresponding collection equipment;

[0024] Step 2: After adding clean water to the cold water tank in the auxiliary structure for cooling, the cold water is pumped out by a liquid pump, flows through one of the second liquefied pipes, enters one end of the first liquefied pipe through one of the heat dissipation pipes, and flows out from the other end, passes through another heat dissipation pipe and another second liquefied pipe, and then flows back into the water tank for circulation. While flowing through the heat dissipation pipes, the fan is driven to accelerate heat dissipation or maintain the cooling effect through the heat sink;

[0025] Step 3: After the liquid enters the separation tank, it is impacted and dispersed by the impact plate in the buckle frame of the impact unit, which is in contact with the inner wall of the separation tank through a rubber pad and sealed. The dispersed water flow is impacted again by the action of the inverted gear and flows into the bottom of the separation tank;

[0026] Step 4: The gas contained in the liquid will drive some liquid molecules to float up, and then pass through the second sieve frame at the bottom of the support rod limited by the support frame to block the water molecules again, and then pass through the first sieve frame with a conical cap structure above to block them, causing the liquid to fall and the gas to float up; the same principle is followed again after passing through the first and second sieve frames, and then the gas flows to the top of the separation tank;

[0027] Step 5: At this time, due to the internal pressure, the gas will pass through the bottom cover of the filter assembly and the air filter installed through the top cover, isolating the water vapor and allowing the gas to be discharged;

[0028] Step 6: While repeatedly breaking up the liquid and filtering the gas, the gas, water vapor, and water molecules will all come into contact with the U-shaped first liquefied pipe. Due to the temperature of the internal cold water, the water molecules will condense and adhere to the first liquefied pipe, slowly condense and fall, so that the gas and water vapor are processed again in the separation tank to prevent them from being discharged together with the gas, thereby improving the separation efficiency.

[0029] Step 7. The exhausted gas enters the liquefied barrel through the air guide pipe, and decomposes the water molecules again through condensation with the second liquefied pipe to improve the purity of the gas for liquefaction. Finally, the separated gas is discharged through the outlet pipe; the liquid can be discharged from the valve and the drain pipe respectively. During use, the liquid level in the separation tank can be detected by the liquid level detector to prevent the liquid level from exceeding the bottom of the buckle rack.

[0030] The gas-liquid separation device and separation method for the analytical treatment of dimethylcyclohexylamine proposed in the present invention have the following beneficial effects:

[0031] 1. The present invention facilitates disassembly and assembly of the entire device through the separation structure, and impacts and disperses the incoming liquid, accelerating the separation of gas in the water body;

[0032] 2. The present invention can disperse the liquid contained in the gas four times during the upward discharge of the dispersed gas through the separation component, thereby improving the water filtration efficiency and discharging the gas after filtering through multiple layers of gas filter nets;

[0033] 3. In order to remove residual liquid compounds from the discharged gas, the present invention pre-cools and liquefies the gas inside the separation tank and when the gas is led out into the liquefaction barrel through the first and second liquefaction pipes with lower temperatures. The gas is then processed again using a simple condensation principle to improve its purity before being discharged. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Example: According to the specification Figure 1-5 It can be seen that

[0058] A separation method of a gas-liquid separation device for dimethylcyclohexylamine analytical treatment, comprising the following steps

[0059] Step 1: Power on the device through the stable support of the base 1, connect the material conveying pipe to the feed pipe 24 in the separation structure 2 to convey the liquid, and connect the discharge pipe 22 to the corresponding collection equipment;

[0060] Step 2: After adding clean water to the cold water tank 31 in the auxiliary structure 3 for cooling, the cold water is pumped by the liquid pump 32, flows through one of the second liquefied pipes 38, enters one end of the first liquefied pipe 37 through one of the heat dissipation pipes 39, and flows out from the other end. After passing through another heat dissipation pipe 39 and another second liquefied pipe 38, it returns to the water tank 31 for circulation. While flowing through the heat dissipation pipe 39, the fan 34 drives the heat sink 33 to accelerate heat dissipation or maintain the cooling effect.

[0061] Step 3: After the liquid enters the separation tank 21, it is impacted and dispersed by the impact plate 72 in the buckle frame 71 of the impact unit 55, which is in contact and sealed with the inner wall of the separation tank 21 through the rubber pad 73. The dispersed water flow is then impacted again by the action of the inverted gear and flows into the bottom of the separation tank 21.

[0062] Step 4: The gas contained in the liquid will drive some liquid molecules to float up, and then pass through the second sieve frame 54 at the bottom of the support rod 52 limited by the support frame 51 to block the water molecules, and then pass through the first sieve frame 53 with a conical cap structure above to block them, causing the liquid to fall and the gas to float up; the same principle is followed again after passing through the first sieve frame 53 and the second sieve frame 54, and then the gas flows to the top of the separation tank 21;

[0063] Step 5: At this time, due to the internal pressure, the gas will pass through the bottom cover 61 of the filter assembly and the air filter 63 installed through the top cover 62, isolating the water vapor and allowing the gas to be discharged;

[0064] Step 6: While repeatedly breaking up the liquid and filtering the gas, the gas, water vapor, and water molecules will all contact the U-shaped first liquefaction pipe 37. Due to the temperature of the internal cold water, the water molecules will condense and adhere to the first liquefaction pipe 37, slowly condense and fall, so that the gas and water vapor are processed again in the separation tank 21 to prevent them from being discharged together with the gas, thereby improving the separation efficiency.

[0065] Step 7: The exhausted gas enters the liquefaction barrel 35 through the air guide pipe, and is condensed and decomposed into water molecules again through the second liquefaction pipe 38 to improve the purity of the gas and liquefy it. Finally, the separated gas is discharged through the outlet pipe; and the liquid can be discharged from the valve 36 and the drain pipe 22 respectively. During use, the liquid level in the separation tank 21 can be detected by the liquid level detector 23 to prevent the liquid level from exceeding the bottom of the buckle rack 71.

The two ends of the second liquefied pipe (38) are respectively fixedly passed through the liquefied barrel (35). In the upper wall of the barrel (35) and the right side wall of the liquefaction barrel (35), the right end of one of the second liquefaction pipes (38) is connected to the liquid outlet end of the liquid pump (32) through a second pipe, wherein the right end of another second liquefaction pipe (38) is connected to a return pipe, and the other end of the return pipe is placed on the inner front side wall of the cold water tank (31), and one end of the heat dissipation pipe (39) is detachably connected to the upper end of the second liquefaction pipe (38), and the other end is detachably connected to the two ends of the first liquefaction pipe (37); The first liquefaction pipe (37) is a U-shaped copper structure; The side wall edges of the first sieve frame (53) and the second sieve frame (54) are respectively in close contact with the inner side wall of the separation tank (21) and sealed.

2. A gas-liquid separation device for dimethylcyclohexylamine analysis and treatment according to claim 1, characterized in that: The separation method includes the following steps: Step 1: The device is powered on by the stable support of the base (1), and the material conveying pipe is connected to the feed pipe (24) in the separation structure (2) to convey the liquid, and the discharge pipe (22) is connected to the corresponding collection device; Step 2: After adding clean water to the cold water tank (31) in the auxiliary structure (3) for cooling, the cold water is driven by the liquid pump (32) to extract the cold water, which flows through one of the second liquefaction pipes (38), enters one end of the first liquefaction pipe (37) through one of the heat dissipation pipes (39), and flows out from the other end, passes through another heat dissipation pipe (39) and another second liquefaction pipe (38), and then flows back to the water tank (31) for cooling. The liquid circulates, and while flowing through the heat dissipation pipe (39), it is driven by the fan (34) to accelerate the heat dissipation or maintain the cooling effect through the heat sink (33); Step 3, after the liquid enters the separation tank (21), it is relatively impacted and dispersed by the impact plate (72) in the buckle frame (71) that contacts and seals the inner wall of the separation tank (21) through the rubber pad (73) in the impact unit (55), and the dispersed water flow is relatively impacted again by the action of the inverted gear table and flows into the bottom of the separation tank (21); Step 4, the gas contained at this time will drive a certain amount of liquid molecules to float up, and pass through the second sieve frame (54) at the bottom of the bearing rod (52) limited by the bearing frame (51) The gas flows through the first sieve frame (53) and the second sieve frame (54) again according to the same principle, and then flows to the top of the separation tank (21); Step 5: At this time, due to the internal pressure, the gas will pass through the bottom cover (61) in the filter gas assembly and the filter net (63) installed through the top cover (62), isolating the water vapor and discharging the gas; Step 6: While repeatedly breaking up the liquid and filtering the gas, the gas, water vapor and water molecules will contact the U-shaped first liquefied pipe (37). Angle, therefore, water molecules will condense and adhere to the first liquefaction pipe (37), slowly condense and drip, so that the gas and water vapor are processed again in the separation tank (21), preventing them from being discharged together with the gas, thereby improving the separation efficiency; Step seven, the discharged gas enters the liquefaction barrel (35) through the air guide pipe, and condenses water molecules again through the second liquefaction pipe (38), thereby improving the gas purity and liquefying, and finally the separated gas is discharged through the gas outlet pipe; and the liquid can be discharged from the valve (36) and the drain pipe (22) respectively, and during use, the liquid level in the separation tank (21) can be detected by the liquid level detector (23) to prevent the liquid level from exceeding the bottom of the buckle rack (71).
