After the amine gas is delivered from the central amine supply source, it is stored in the storage tank 1 in liquid form. When in use, it is delivered to the gas blowing device and output together with the gas generator. This is prior art and will not be described in detail here. A flame arrester 5 is installed on the top of the storage tank 1 to improve the safety of the storage tank 1. A level gauge 6 is also installed in the storage tank 1. The probe of the level gauge 6 is located inside the storage tank 1 to monitor the storage amount of amine gas so as to replenish the amine gas. A switch valve 7 is installed on the liquid outlet pipe 4. A filter 8 is installed on the liquid outlet pipe 4 behind the switch valve 7 to prevent impurities from entering the blowing equipment and causing blockage. An exhaust assembly 9 is installed on the blowing equipment 2 above the storage tank 1. The exhaust assembly 9 includes an exhaust fan 901, a conical hood 902 and an exhaust pipe 903. The exhaust fan 901 is connected to the blowing equipment 2 through a bracket. The large end of the conical hood 902 is installed at the air outlet of the exhaust fan 901. The small end of the conical hood 902 is connected to the exhaust pipe 903. The end of the exhaust pipe 903 extends into the waste gas treatment pool. The waste gas treatment pool is a treatment pool in the prior art, used to treat waste gas, which will not be described in detail here.

[0024] The buffer device in this embodiment improves the safety of the storage tank 1 by installing a flame arrester 5 on the storage tank 1, and prevents impurities from entering the blowing device 2 and causing blockage by installing a filter 8 on the liquid outlet pipe 4. At the same time, by installing an exhaust assembly 9 above the storage tank 1, the storage tank is in a ventilated state. Once amine gas leaks, the exhaust fan can promptly remove it, avoiding the problem of amine gas poisoning and effectively improving production safety.

[0025] Preferably, the filter 8 in this embodiment includes a filter cartridge 801, a filter screen 802, and a plug 803. The filter cartridge 801 is inclinedly fixed to the bottom of the outlet pipe 4 and is connected to the outlet pipe 4. The filter screen 802 is movably inserted into the filter cartridge 801, with one end pressed against the inner wall of the outlet pipe 4. The plug 803 is threadedly connected to the end of the filter cartridge 801 away from the outlet pipe 4 and adheres to the other end of the filter screen 801, so that amine gas is filtered by the filter screen 802 when passing through the filter cartridge 801.

[0026] The buffer device in this embodiment has a filter 8 with a structure of filter cartridge 801, filter screen 802 and plug 803. When amine gas passes through the filter 8, impurities are filtered out by the filter screen 802, thus achieving the purpose of amine gas filtration. During maintenance, the filter screen can be removed and cleaned by loosening the plug 803, which is very convenient. In addition, the design of the magnet block 805 can adsorb iron powder, further improving the filtration effect.

[0028] Example 2

[0029] See Figure 4 This is another specific embodiment of the present invention. This embodiment is basically the same as Embodiment 1, except that the storage tank 1, the inlet pipe 3, and the outlet pipe 4 all have a double-layered cavity 12 structure, which is far from the pipeline for storing and transporting combustible gas, further improving the safety of amine gas transportation. Furthermore, the double-layered cavities 12 corresponding to the storage tank 1, the inlet pipe 3, and the outlet pipe 4 are all connected to the conical shroud 902 through pipes. The outer walls of the storage tank 1, the inlet pipe 3, and the outlet pipe 4 are all equipped with one-way valves 11 that communicate with their corresponding double-layered cavities 12. The one-way valve 11 is defined as an installation method that allows gas to enter only into the double-layered cavities 12, so that the exhaust assembly can draw away the gas in the double-layered cavities 12.

[0030] The buffer device of this utility model has a double-layered cavity 12 structure for its storage tank 1, inlet pipe 3, and outlet pipe 4. On the one hand, it can improve their structural strength, and on the other hand, it can further prevent the problem of amine gas leakage and poisoning, which meets the standards for toxic gas transportation. At the same time, the storage tank 1, inlet pipe 3, and outlet pipe 4 are all connected to the exhaust assembly 9, so that in the event of amine gas leakage, it can be removed at any time, further improving production safety.

[0031] The above are merely preferred embodiments of this utility model.
