Embodiment Construction

[0019] Such as figure 1 , 2 , 3, the plasma waste gas treatment device of the present invention includes a mounting frame 1, a sealing casing 2 arranged on the outer surface of the mounting frame 1, and the sealing casing 2 is provided with a waste gas inlet 201 and a waste gas outlet 202. A plasma reaction unit 5 is arranged inside the sealed casing 2, and the plasma reaction unit 5 includes a negative electrode tube 503 with a discharge tip 504 on the outer surface, and a positive electrode tube 502 concentric with the negative electrode tube 503 and sleeved outside the negative electrode tube 503. The top end of the positive tube 502 is provided with a spray device 3 for flushing the inner surface of the positive tube.

[0020] The specific exhaust gas inlet 201 is opened on the sealed casing 2 opposite to one end of the positive electrode tube 502, and the exhaust gas outlet 202 is opened on the sealed casing 2 opposite to the other end of the positive electrode tube. Dur...

Abstract

The invention discloses a plasma waste-gas treatment device with a self-flushing function. The device includes a mounting rack and a seal housing arranged on an outer side surface of the mounting rack. A waste-gas inlet and a waste-gas outlet are disposed on the seal housing. A plasma reaction unit is arranged in the seal housing. The plasma reaction unit includes negative electrode pipes, each having a discharging tip disposed on the external surface thereof, and positive electrode pipes, each concentrically sleeving each negative electrode pipe. The plasma reaction unit is characterized in that a spray device for flushing inner surfaces of the positive electrode pipes is disposed on the top of the positive electrode pipes. According to the invention, a set of spray device is installed on the plasma waste-gas treatment device. Through switching work states of the plasma waste-gas treatment device, the spray device is automatically started to flush the inside of the treatment device to remove dust and tar adhered on the inner surface of the device because of humidity. An adjusting device ensures that each negative electrode pipe is in the center of the positive electrode pipe, so reactions are uniformly carried out in each positive electrode pipe with guarantee of smoke treatment effect.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a cutting-edge discharge waste gas treatment device for treating flue gas generated after tobacco is processed by a dry ice expansion shredded tobacco method. Background technique [0002] In the tobacco industry, the dry ice-expanded shredded tobacco technology used to treat tobacco is a shredded tobacco expansion method with dry ice as the expansion medium. Its advantages are high filling value, which can effectively reduce the tar content and miscellaneous gas in tobacco and improve the quality of cigarettes. Product quality is the method of expanding shredded tobacco commonly used at home and abroad. Dry ice expanded cut tobacco production line is mainly divided into cold end and hot end. The cold end includes feeding system, recovery system and impregnation system, and the hot end includes combustion furnace system, expansion circulation system and moisture regain system. The combust...
