本发明中的废气油浴处理装置设置为内外两侧结构，在外管21内放置硅油，外管21和内管22通过连通管24连接，至少具有以下有益效果：The waste gas oil bath treatment device in the present invention is set as an inner and outer structure, and silicone oil is placed in the outer tube 21, and the outer tube 21 and the inner tube 22 are connected by a connecting tube 24, which at least has the following beneficial effects:
1.从烧结炉排出的废气混合气体沿着进气口先进入内管22，将内管22充满以后，沿着位于底部的连通管24的一端端口进入连通管24，经由连通管24进入外管21内的硅油油浴中，如此设置，比较于将排气管12的排气端直接插入硅油的方式，避免了排气管12与硅油直接接触，在烧结炉内压力有突变时，内管22内的空间作为缓冲紊流空间，不存在废气气流跳动而引起硅油晃动的危险；1. The exhaust gas mixture discharged from the sintering furnace first enters the inner pipe 22 along the air inlet. After filling the inner pipe 22, it enters the connecting pipe 24 along one end port of the connecting pipe 24 at the bottom, and enters the outer pipe through the connecting pipe 24 In the silicone oil bath in 21, this arrangement, compared with the way of directly inserting the exhaust end of the exhaust pipe 12 into the silicone oil, avoids direct contact between the exhaust pipe 12 and the silicone oil. When there is a sudden change in the pressure in the sintering furnace, the inner pipe The space inside 22 is used as buffer turbulence space, and there is no risk of silicone oil sloshing caused by fluttering exhaust gas flow;
2.连通管24和内管22的设置，避免了排气管12与硅油的直接接触，由于烧结炉内是高真空负压状态，而外界是常压或正压环境，排气管12与烧结炉内是连通的，若出现操作不当或气体泄露时，外界正压环境会将空气沿着气体点燃装置内的连接管、及与废气油浴处理装置的出气口连接的连接管倒压回废气油浴处理装置内，此时进入外管21的外界气体沿着连通管24将硅油倒压会内管22内，而外管21内盛放的硅油的量最大将内管22充满，而不会使硅油直接沿着进气口及排气管12倒压回烧结炉内，造成安全事故，而且，在硅油被沿着连通管24倒压回内管22时，操作人员可以明确看到，也可以及时制止这种情况的发生；比较于将排气管12的排气端直接插入硅油的方式，此种情况发生时，硅油直接被外界正压倒压至沿着排气管12进入炉体内，造成安全事故；2. The setting of the connecting pipe 24 and the inner pipe 22 avoids the direct contact between the exhaust pipe 12 and the silicone oil. Since the inside of the sintering furnace is in a high vacuum negative pressure state, while the outside is in a normal or positive pressure environment, the exhaust pipe 12 and the silicon oil The inside of the sintering furnace is connected. If there is improper operation or gas leakage, the external positive pressure environment will push the air back along the connecting pipe in the gas ignition device and the connecting pipe connected to the gas outlet of the waste gas oil bath treatment device. In the exhaust gas oil bath treatment device, the outside gas entering the outer pipe 21 at this time pushes the silicone oil back into the inner pipe 22 along the connecting pipe 24, and the amount of silicone oil contained in the outer pipe 21 is the largest to fill the inner pipe 22, while It will not cause the silicone oil to be directly pressed back into the sintering furnace along the air inlet and exhaust pipe 12, causing a safety accident. Moreover, when the silicone oil is pushed back into the inner pipe 22 along the connecting pipe 24, the operator can clearly see , can also prevent this from happening in time; compared to the way of directly inserting the exhaust end of the exhaust pipe 12 into the silicone oil, when this happens, the silicone oil is directly overwhelmed by the external positive pressure to enter the furnace along the exhaust pipe 12 body, causing a safety accident;
3.连通管24和内管22的设置，拉长了剩余气体中氢气排出的路径，同样也拉长了氢气回火的路径，在点燃装置中，氢气是可燃气体，如果采用现有的将排气管12的排气端直接插入硅油的方式，点燃的氢气有时候会沿着点燃装置内的连接管直接进入硅油内，然后沿着进气口进入炉体内，造成安全事故，而本发明中即使点燃的氢气有时候会沿着点燃装置内的连接管、及与废气油浴处理装置的出气口连接的连接管进入废气油浴处理装置中，此时氢气或点燃的氢气只能在外管21内部存在，而不会直接进入内管22中，更不会沿着进气口进入炉体内。3. The setting of the connecting pipe 24 and the inner pipe 22 lengthens the path of hydrogen discharge in the remaining gas, and also lengthens the path of hydrogen tempering. In the ignition device, hydrogen is a combustible gas. If the existing In the way that the exhaust end of the exhaust pipe 12 is directly inserted into the silicone oil, the ignited hydrogen will sometimes enter the silicone oil directly along the connecting pipe in the ignition device, and then enter the furnace body along the air inlet, causing a safety accident. Even the ignited hydrogen sometimes enters the waste gas oil bath treatment device along the connecting pipe in the ignition device and the connecting pipe connected to the outlet of the waste gas oil bath treatment device. 21 exists inside, and can not directly enter in the inner pipe 22, more can not enter the furnace body along the air inlet.
