[0027] Example 1

[0028] Reference Figure 1 , provides a device for automatic blowdown of an IGCC acid gas flame arrester, comprising,

[0029] Sour gas flare 100;

[0030] A flame arresting mechanism 200 connected to the acid gas torch 100;

[0031] A sewage discharge mechanism 400 is provided between the acid gas flare 100 and the flame arresting mechanism 200;

[0032] The acid gas torch 100 safely handles and burns the acid gas. The flame arrester 200 can prevent the flame of flammable gas and flammable liquid vapor from spreading, and prevent the spread of flame deflagration or detonation. Through the settings of the two, the purpose of safe production is achieved, and the condensate at the flame arrester 200 is discharged through the sewage discharge mechanism 400.

[0033] Furthermore, the acid gas torch 100 is connected to the flame arrester mechanism 200 via a connecting pipe 300; a drain mechanism 400 is disposed on the connecting pipe 300; by disposing the flame arrester mechanism 200 on the connecting pipe 300, the flame is prevented from spreading from the pipeline connected to the acid gas torch 100, and by disposing the drain mechanism 400 on the connecting pipe 300, the condensate at the front end of the flame arrester mechanism 200 can be discharged by the drain mechanism 400.

[0034] Furthermore, the sewage discharge mechanism 400 includes a sewage discharge pipe 401, which is fixed on the connecting pipe 300; the sewage discharge pipe 401 enables the device to have a channel for condensate.

[0035] Furthermore, a remote pneumatic valve 402 is installed on the sewage pipe 401 ; the remote pneumatic valve 402 can control the opening and closing of the sewage pipe 401 .

[0036] Furthermore, the remote pneumatic valve 402 is wirelessly connected to a remote control device, and the remote control device can control the opening and closing of the remote pneumatic valve 402;

[0037] By connecting the remote pneumatic valve 402 with the remote control device, the remote pneumatic valve 402 can be opened and closed by wireless control, so that there is no need for manual on-site operation and remote control is sufficient.

[0038] Furthermore, the acid gas flare 100 includes a flare head 101 and a barrel 102 disposed at the bottom of the flare head 101;

[0039] The connecting pipe 300 is disposed between the cylinder 102 and the fire arresting mechanism 200 ; in this embodiment, the fire arresting mechanism 200 is preferably a flame arrester.

[0040] Furthermore, a hand valve 403 is provided at the front end of the remote control valve in the sewage pipe 401; by retaining the hand valve 403, the safety of the equipment is further improved. When the remote pneumatic valve 402 fails, the opening and closing of the sewage pipe 401 can be controlled by the hand valve 403.

[0041] Furthermore, the wireless control device can set the opening time and opening interval of the remote pneumatic valve 402;

[0042] The automatic sewage discharge setting of the remote start valve can be realized through the wireless control device, for example: sewage discharge for 2 minutes every 1 hour, and the sewage discharge frequency and sewage discharge time can be changed at any time according to the burning conditions of the acid torch and the amount of liquid during sewage discharge, thereby ensuring the sewage discharge effect.

[0043] The flame arrester realizes the function of automatic sewage discharge, reducing the workload of on-site inspection personnel; through automation improvement, the labor cost is greatly reduced, the condensate of the acid flare pipeline can be discharged on time, and the automatic sewage discharge effect is enhanced. The sewage medium of the flame arrester is toxic and harmful gas, and the operation risk of on-site personnel is realized through remote automatic sewage discharge; through automation improvement, the safe and stable operation of the acid flare is realized, and the occurrence of environmental protection incidents is avoided.

[0044] Example 2

[0045] Reference Figure 1This embodiment is different from the first embodiment in that a high liquid level switch 404 is further provided between the connecting pipe 300 and the manual valve 403 ; the high liquid level switch 404 is signal-connected to the remote pneumatic valve 402 .

[0046] By setting a high liquid level switch 404, when there is a lot of liquid in the pipeline, the high liquid level switch 404 can be triggered, and it can be interlocked to automatically open the remote start valve to discharge sewage; then the high liquid level switch 404 monitors the accumulation of condensate in the acid torch pipeline, discharges sewage in time, and ensures the stable combustion of the acid torch;

[0047] By adding a high liquid level switch 404 for use in conjunction with the remote pneumatic valve 402, precise control of the sewage discharge process is achieved. The remote pneumatic valve 402 can be automatically opened and closed according to a preset program, and the high liquid level switch 404 is used as a monitoring device. When it is detected that condensate has accumulated to a certain extent, it automatically triggers the sewage discharge valve to ensure timely discharge.

[0048] The rest of the structure is the same as that of Example 1.

[0049] Example 3

[0050] Reference Figure 1 , this embodiment is different from the above embodiment in that:

[0051] The above-mentioned sewage discharge mechanism 400 is set in an experimental device to verify the sewage discharge effect of the sewage discharge mechanism 400;

[0052] The amount of sewage liquid discharged from the pipeline is set to the same fixed volume, and the remote transmission pneumatic valve 402 is set to several different sewage discharge frequency and sewage discharge time combinations, and the sewage discharge effect under each combination is observed. The sewage discharge effect is measured by sewage discharge efficiency and sewage discharge thoroughness;

[0053] The drainage efficiency is expressed by the amount of liquid discharged per unit time, while the drainage thoroughness is expressed by the amount of liquid remaining after drainage;

[0054] The following are the test results:

[0055]

[0056] In this table, we can see that the sewage discharge efficiency does not increase with the increase of sewage discharge time, but there is an optimal sewage discharge time that makes the sewage discharge efficiency the highest. At the same time, the sewage discharge thoroughness also increases with the increase of sewage discharge time, but too short sewage discharge time may lead to incomplete sewage discharge;

[0057] The selection of the optimal blowdown frequency and blowdown time needs to be determined according to the actual situation, such as the maximum treatment capacity of the blowdown system, the operating requirements of the acid flare, and the working hours of the operators. In the above experimental data, we can see that the combination of a blowdown frequency of 0.5 times / hour and a blowdown time of 4 minutes provides the highest blowdown thoroughness (95%), and the blowdown efficiency is also relatively high (50%). This is a more ideal choice because it takes into account the actual work needs of the operators while ensuring the thoroughness of the blowdown.

[0058] The rest of the structure is the same as that of Example 2.
