A waste gas oil bath treatment device comprises an outer pipe, an inner pipe, a sealing plate and a communication pipe. One end of the communication pipe stretches into the inner pipe, the other end of the communication pipe stretches into an interlayer cavity between the outer pipe and the inner pipe so that the outer pipe can communicate with the inner pipe. The interior of the outer pipe is filled with silicon oil for treating waste gas, the other end of the communication pipe stretches into the silicon oil. The sealing plate is further provided with an air inlet and an air outlet, the airinlet communicates with the interior of the inner pipe, and the air outlet communicates with the interlayer cavity. According to the waste gas oil bath treatment device, the air inlet and the air outlet are in isolated communication through the arrangement of the inner pipe and the communication pipe, and the situations that hydrogen tempering happens and outside positive-pressure gas enters a furnace body directly along the air inlet are avoided; and on the premise that sufficient oil bath is guaranteed, safety running of a sintering furnace is guaranteed. According to the sintering furnace,three-level treatment of waste gas is achieved, pollution-free emission is achieved, and the national environment protection requirement is met.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment from high-temperature sintering furnaces, in particular to a waste gas oil bath treatment device and a multi-stage waste gas treatment type vacuum atmosphere sintering furnace. Background technique [0002] The gases used in the process of processing metal and non-metal materials in high-temperature sintering furnaces mainly include hydrogen, argon, nitrogen, etc. Argon and nitrogen are only used as protective gases during the sintering process of the material and do not participate in the sintering reaction of the material. Except for a part of the hydrogen gas participating in the sintering reaction, the rest of the exhaust gas is discharged through the sintering furnace, usually by means of combustion. [0003] Existing sintering furnaces are equipped with exhaust gas ignition devices, but there are no treatment measures for other gases, causing the emitted gases to pollute the atmo...
