Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide emission technology, specifically to a carbon dioxide gas emission device for a desorption tower. Background Technology

[0002] Carbon dioxide is a byproduct of the reaction in the device. After being absorbed by potassium carbonate in the absorption tower, carbon dioxide is released by depressurization and heating in the desorption tower, thereby achieving the effect of separating carbon dioxide from the system.

[0003] In existing technologies, carbon dioxide emissions are discharged from a desorption tower to an incineration system for treatment. A vent pipe is installed after the shut-off valve of the carbon dioxide emission pipeline. Since this gas contains a small amount of organic gas, which can cause the VOCs (volatile organic compounds) content to exceed the standard, direct venting is prohibited due to environmental protection requirements. If the incineration system is shut down or under maintenance, the carbon dioxide cannot be discharged, causing the unit to stop, resulting in huge losses and environmental safety issues. Therefore, a carbon dioxide gas emission device for desorption towers is proposed. By installing a T-junction and an outlet pipe on the vent pipe, carbon dioxide can be transported from the T-junction and outlet pipe to the flare for incineration after the shut-off valve on the vent pipe is closed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a carbon dioxide gas emission device for desorption towers. By setting a tee and an outlet pipe on the vent pipe, carbon dioxide can be transported from the tee and the outlet pipe to the flare for incineration after the shut-off valve on the vent pipe is closed.

[0005] The technical solution adopted by this utility model to solve its technical problem is a carbon dioxide gas emission device for desorption tower, including a three-way valve and a second connecting pipe. The top end of the three-way valve is connected to the first connecting pipe through a threaded groove. The top end of the first connecting pipe is connected to the gas outlet pipe through a pipe joint. A cylinder is provided at one end of the gas outlet pipe.

[0006] The drive motor is installed inside the cylinder by a mounting bracket, and the output shaft on one side of the drive motor is fitted with fan blades by a flat key.

[0007] By adopting the above technical solution, after the shut-off valve on the vent pipe is closed, carbon dioxide flows through the connecting pipe to the outlet pipe, and is then transported from the outlet pipe to the flare for incineration. The drive motor drives the fan blades to rotate, blowing the airflow into the outlet pipe.

[0008] Specifically, a solenoid valve is sleeved on the outside of the first connecting pipe, and a first one-way valve is sleeved on the outside of the first connecting pipe at the top of the solenoid valve.

[0009] Specifically, an air vent is provided at one end of the cylinder, and a second connecting pipe is provided at one end of the air vent. The cylinder is connected to one end of the air vent through the second connecting pipe.

[0010] Specifically, a second one-way valve is connected between the air outlet pipe and the second connecting pipe via a threaded groove, and a flow meter is sleeved on the outside of the air outlet pipe.

[0011] Specifically, a dustproof net is fixed to one end of the cylinder by bolts.

[0012] Specifically, a flange ring is provided at the end of the air outlet pipe away from the cylinder.

[0013] The beneficial effects of this utility model are:

[0014] (1) The carbon dioxide gas emission device for desorption tower described in this utility model, when the external control equipment controls the shut-off valve on the vent pipe to cut off the vent pipe, simultaneously gives a signal to the solenoid valve to open it, so that carbon dioxide can flow into the gas outlet pipe through the first connecting pipe, and then be transported to the flare for incineration treatment through the gas outlet pipe, ensuring the normal emission of carbon dioxide gas from the device, without affecting the system operation or causing environmental pollution.

[0015] (2) The carbon dioxide gas emission device for desorption tower described in this utility model drives the fan blades to rotate at high speed, drawing external gas into the cylinder, and then transporting it to the outlet pipe through the outlet hood and the second connecting pipe. The strong airflow blows into the outlet pipe, which can blow the carbon dioxide flowing into the outlet pipe into the flare, preventing the carbon dioxide in the outlet pipe from not flowing into the flare due to pressure difference and temperature.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] By installing a tee and an outlet pipe on the vent pipe, carbon dioxide can be transported from the tee and outlet pipe to the flare for combustion after the shut-off valve on the vent pipe is closed. Figure 1-2 As shown, the carbon dioxide gas emission device for desorption tower of this utility model includes a three-way valve 1 and a second connecting pipe 12. The top end of the three-way valve 1 is connected to the first connecting pipe 2 through a threaded groove. The top end of the first connecting pipe 2 is connected to the gas outlet pipe 3 through a pipe joint. A cylinder 4 is provided at one end of the gas outlet pipe 3.

[0022] The drive motor 9 is installed inside the cylinder 4 via a mounting bracket, and the output shaft on one side of the drive motor 9 is fitted with a fan blade 10 via a flat key.

[0023] When in use, after the shut-off valve on the vent pipe is closed, carbon dioxide flows through the first connecting pipe 2 to the outlet pipe 3, and is then transported from the outlet pipe 3 to the torch for incineration. The drive motor 9 drives the fan blades 10 to rotate, blowing the airflow into the outlet pipe 3.

[0024] For example, such as Figure 1 As shown, the present invention also includes a solenoid valve 5 sleeved on the outside of the first connecting pipe 2, and a first one-way valve 6 sleeved on the outside of the top of the solenoid valve 5 on the first connecting pipe 2.

[0025] When in use, after the solenoid valve 5 is opened, the carbon dioxide in the vent pipe flows through the first connecting pipe 2 to the outlet pipe 3. The first one-way valve 6 can prevent the carbon dioxide in the outlet pipe 3 from flowing back into the vent pipe through the first connecting pipe 2.

[0026] For example, such as Figure 2 As shown, the present invention also includes an air vent 11 provided at one end of the cylinder 4, a second connecting pipe 12 provided at one end of the air vent 11, and the cylinder 4 connected to one end of the air vent 3 through the second connecting pipe 12.

[0027] In use, the air outlet hood 11 facilitates the airflow inside the cylinder 4 to be blown into the air outlet pipe 3, and the second connecting pipe 12 facilitates the connection between the cylinder 4 and the air outlet pipe 3.

[0028] For example, such as Figure 1 As shown, the present invention also includes a second one-way valve 8 connected between the air outlet pipe 3 and the second connecting pipe 12 via a threaded groove, and a flow meter 7 is sleeved on the outside of the air outlet pipe 3.

[0029] When in use, the second one-way valve 8 is set to prevent carbon dioxide in the outlet pipe 3 from flowing into the cylinder 4, and the flow meter 7 is set to detect and display the flow rate of carbon dioxide in the outlet pipe 3.

[0030] For example, such as Figure 2As shown, the present invention also includes a dustproof net 13 fixed to one end of the inner side of the cylinder 4 by bolts.

[0031] When in use, the dust filter 13 is designed to filter out external dust, impurities, etc.

[0032] For example, such as Figure 1 As shown, the present invention also includes a flange ring 14 provided at the end of the air outlet pipe 3 away from the cylinder 4.

[0033] During use, bolts can be used to fix the end of the air outlet pipe 3 through the flange ring 14.

[0034] In use, the three-way valve 1 is connected to the vent pipe of the desorption tower, the solenoid valve 5 is connected to the shut-off valve control device on the vent pipe using a power cord, one end of the gas outlet pipe 3 is fixed to the torch using bolts through the flange ring 14, and the device is connected to an external power source using a power cord.

[0035] When the external control equipment controls the shut-off valve on the vent pipe to shut off the vent pipe, it simultaneously sends a signal to the solenoid valve 5 to open it. Carbon dioxide can flow through the first connecting pipe 2 to the outlet pipe 3, and then be transported through the outlet pipe 3 to the flare for incineration. This ensures the normal emission of carbon dioxide gas from the device, without affecting system operation or causing environmental pollution.

[0036] When the drive motor 9 is turned on, the fan blades 10 are driven to rotate at high speed. External gas can be drawn into the cylinder 4 through the dustproof net 13, and then transported to the outlet pipe 3 through the outlet hood 11 and the second connecting pipe 12. The strong airflow blows into the outlet pipe 3, which can blow the carbon dioxide flowing into the outlet pipe 3 into the torch, preventing the carbon dioxide in the outlet pipe 3 from not flowing into the torch due to pressure difference and temperature.

[0037] The first one-way valve 6 is set to prevent carbon dioxide flowing into the outlet pipe 3 from flowing back. The flow meter 7 is set to detect and display the flow rate of carbon dioxide in the outlet pipe 3. The second one-way valve 8 is set to prevent carbon dioxide in the outlet pipe 3 from flowing into the cylinder 4.

[0038] Personnel can also fix one end of the vent pipe 3 to the gas storage tank through the flange ring 14. When the shut-off valve on the vent pipe cuts off the vent pipe, carbon dioxide can be transported to the gas storage tank through the first connecting pipe 2 and the vent pipe 3, ensuring the normal emission of carbon dioxide gas from the device.
