Referring to fig. 1, a non-condensable gas treatment apparatus according to a preferred embodiment of the present utility model will be described in detail below, and the non-condensable gas treatment apparatus is used for incinerating non-condensable gases, such as small amounts of hydrocarbons, carbon monoxide, etc.

Referring to fig. 2 to 4, in particular, the non-condensable gas treatment apparatus includes an incinerator 10 and a heat insulating layer assembly 20. The incinerator 10 includes a main body 11. The insulation pack assembly 20 includes an insulation housing 21 and a refractory insulation pack 22.

The furnace body 11 is accommodated in the heat insulation housing 21, and a heat-blocking gap 10001 which can be communicated with the outside is formed between the outer wall of the furnace body 11 and the inner wall of the heat insulation housing 21. The furnace body 11 forms an incineration chamber 1101, at least one air inlet 1102 communicating with the incineration chamber 1101, and at least one air outlet 1103 communicating with the incineration chamber 1101. The refractory and heat insulating layer 22 is installed on the furnace body 11 to insulate the heat in the incinerator 1101 from being diffused.

The gas inlet 1102 is configured to allow non-condensable gas to enter the incineration chamber 1101, the non-condensable gas is combusted in the incineration chamber 1101, and the gas finally generated by the combustion is discharged out of the incineration chamber 1101 through the gas outlet 1103. The fire-resistant heat-insulating layer 22 blocks heat in the incineration chamber 1101 from diffusing outwards, and the heat-resistant gap 10001 can also block part of heat from being conducted to the heat-insulating housing 21, so as to prevent the working environment around the non-condensable gas treatment device from being too high in temperature and causing abnormal operation of staff, and can also avoid poor incineration effect caused by too fast heat dissipation in the incineration chamber 1101.

Referring to fig. 2, in a preferred embodiment, the heat insulating housing 21 has an air-filled gap 2101, a through-inlet communicating with the air-filled gap 2101, and a through-outlet communicating with the air-filled gap 2101, the through-inlet allowing dry air to enter the air-filled gap 2101 and to be discharged through the through-outlet after the dry air is heated.

Preferably, the refractory and heat insulating layer 22 is provided on the inner wall of the incineration chamber 1101 formed by the furnace body 11. In this way, the refractory and heat-insulating layer 22 can protect the incinerator 10, reduce corrosion of the incinerator 10 by high temperature, and prolong the service life of the incinerator 10.

In a preferred embodiment, the refractory and insulating layer 22 is provided as a ceramic fiber material. The heat-resistant heat-insulating layer 22 expands when heated, so that gaps among molecules of the heat-resistant heat-insulating layer 22 are reduced, and a good heat-resistant effect is achieved. The ceramic fiber material is lightweight compared to other insulation materials, making the non-condensable gas treatment device lightweight.

Preferably, a vertical distance between the outer wall of the furnace body main body 11 and the inner wall of the heat insulating housing 21 is set to 80mm to 120mm. In other words, the cross-sectional distance of the heat-blocking gap 10001 is preferably 80mm to 120mm, and the volume of the noncondensable gas processing apparatus is reduced while ensuring the heat-blocking effect.

Preferably, the incinerator 10 further comprises a set of communicating members 12. The communicating member group 12 is provided between the furnace body main body 11 and the heat insulating layer assembly 20 so that the incineration chamber 1101 communicates with the outside.

Specifically, the communication member set 12 includes at least one first communication member 121, and the first communication member 121 is mounted to the furnace body 11 and passes through the heat insulation housing 21 in a sealing manner. An open end of the first communicating member 121 is communicated with the incineration chamber 1101 such that each of the first communicating members 121 communicates with the incineration chamber 1101 and the outside, and each of the first communicating members 121 forms at least one detection channel 12101. The detection channel 12101 is configured to allow a temperature detector and/or a pressure detector to pass through to detect the temperature and/or pressure in the incinerator 1101, so that a worker monitors the operating temperature and pressure of the main body 11.

Preferably, the communication group 12 further includes a second communication 122. The second communication passage 122 is mounted to the furnace body main body 11 and passes through the heat insulating housing 21 in a sealed manner. An open end of the second communicating member 122 is communicated with the incineration chamber 1101 so that each of the second communicating members 122 communicates with the incineration chamber 1101 and the outside. The second communicating member 122 forms an oxygen supply passage 12201 communicating with the incineration chamber 1101 for air or oxygen to enter the incineration chamber 1101 to ensure that non-condensable gases can be completely combusted.

Also preferably, the communication member set 12 further includes a third communication member 123. The third communicating member 123 includes a tube body 1231 and at least one transparent portion 1232. The pipe body 1231 is mounted to the furnace body 11 and passes through the heat insulating housing 21 in a sealed manner. The transparent part 1232 is installed at the pipe orifice of the pipe body 1231, and the condition inside the incineration chamber 1101 can be checked through the transparent part 1232 for the operator to observe.

Referring to fig. 2 and 4, further, the non-condensable gas treatment apparatus further comprises a cooling furnace 30 and at least one cooling tube 40.

Specifically, the cooling furnace 30 forms a cooling chamber 3001. The cooling chamber 3001 is configured to hold a cooling fluid, such as an aqueous solution. The cooling pipe 40 is installed in the cooling chamber 3001, and a part of the cooling pipe 40 is immersed below the liquid level of the cooling liquid contained in the cooling chamber 3001. The cooling tube 40 forms a discharge port 4001. The exhaust port 4001 formed by the cooling pipe member 40 communicates with the outside. An end of the cooling pipe 40 remote from the exhaust port 4001 communicates with the air outlet 1103. The gas generated by combustion of the non-condensable gas in the incinerator 1101 flows into the cooling pipe 40 through the gas outlet 1103 and is finally discharged from the discharge port 4001. It will be appreciated that, during the process of flowing the gas generated by the combustion of the non-condensable gas from the gas outlet 1103 to the gas outlet 4001, the pipe wall of the cooling pipe 40 contacts with the cooling liquid to perform heat exchange, so that the cooling liquid cools the gas generated by the combustion of the non-condensable gas.

It is noted that the cooling furnace 30 forms an exhaust port 3002 communicating with the cooling chamber 3001. The exhaust port 3002 is configured to exhaust vapor generated by heating the cooling liquid. As the cooling liquid is heated to generate a large amount of vapor, the pressure in the cooling chamber 3001 is excessively high, and vapor is released through the exhaust port 3002, so that the pressure of the cooling chamber 3001 is maintained within a safe range. It will be appreciated that releasing the steam through the exhaust port 3002 may be directed to a heat conversion device, such as a steam turbine, to convert heat from the steam into mechanical energy.

Preferably, the cooling pipe 40 is disposed entirely below the liquid level of the cooling liquid contained in the cooling chamber 3001, so as to ensure that the gas flowing in the cooling pipe 40 can exchange heat with the cooling liquid sufficiently, thereby improving the cooling effect.

Referring to fig. 1 and 4, the cooling furnace 30 preferably forms a supplementary port 3003 communicating with the cooling chamber 3001, the supplementary port 3003 being for the cooling liquid to enter the cooling chamber 3001.

In one embodiment, the cooling furnace 30 includes a furnace body 31 and a transparent viewing member 32. The exhaust port 3002 and the replenishment port 3003 are formed in the furnace body 31. The transparent observation element 32 is attached to the furnace body 31, and the flow control valve 60 is attached to the furnace body 31. The inside of the cooling chamber 3001 can be observed through the transparent observation member 32. In this way, a worker can control the opening or closing of the flow control valve 60 by observing the liquid level in the cooling chamber 3001 through the transparent observation member 32, so as to maintain the amount of the cooling liquid in the cooling chamber 3001 within a predetermined range.

As a variant, the non-condensable gas treatment device further comprises a controller 70.

The level gauge 50 is communicatively coupled to the controller 70, and the flow control valve 60 is controllably coupled to the controller 70. The level measuring unit 50 is configured to detect whether the liquid level of the cooling chamber 3001 is higher or lower than the preset range, and transmit the monitoring result to the controller 70, and the controller 70 controls the flow control valve 60 to open or close according to the monitoring result of the level measuring unit 50.

In one example, the level gauge 50 is implemented to include a level gauge.

Referring to fig. 1 and 2, in a preferred embodiment, the furnace body 31 forms at least one discharge port 3101 at a predetermined height. The coolant may be discharged through the discharge port 3101 to ensure that the coolant in the cooling furnace 30 does not exceed a predetermined height.

Further, the furnace body 31 has at least one drain 3102 formed at the bottom for discharging the impurities in the cooling chamber 3001.

Referring to fig. 1, further, the non-condensable gas treatment apparatus further comprises a mounting seat 80.

Specifically, the cooling furnace 30 and the incinerator 10 are both supportingly installed at the installation base 80, and the cooling furnace 30 is connected to the incinerator 10 so that the non-condensable gas treatment apparatus is integrally moved.

Referring to fig. 2, further, the non-condensable gas treatment apparatus further comprises an ignition member 90.

Specifically, the ignition member 90 has a flame outlet 9001, and the ignition member 90 is mounted to the incinerator 10 with the flame outlet 9001 facing the incineration chamber 1101 for igniting non-condensable gas.

In one example, the ignition element 90 is implemented to include a pilot lamp.

Referring to fig. 1, further, the non-condensable gas treatment apparatus further includes a combustion supporting member 100.

Specifically, the combustion supporting member 100 communicates with the oxygen supply passage 12201. The combustion supporting member 100 is arranged to supply air or oxygen to the combustion chamber 1101 through the oxygen supply passage 12201 to provide oxygen for combustion of non-condensable gases.
