Plasma waste-gas treatment device with self-flushing function

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...

Problems solved by technology

[0004] In order to solve the problem that the existing cutting-edge discharge equipment is not suitable for the treatment of high-humidity and tar-containing tobacco waste gas, the present invention provides a plasma waste gas treatment device with automatic flushing function for treating tobacco waste gas. The specific scheme is as follows: with self-flushing function The plasma exhaust gas treatment device comprises a mounting frame, a sealed casing arranged on the outer side of the mounting frame, an exhaust gas inlet and an exhaust gas outlet are arranged on the sealed casing, and a plasma reaction unit is arranged in the sealed casing, and the plasma reaction The unit includes a negative electrode tube with a discharge tip on the outer surface, and a positive electrode tube that is concentric with the negative electrode tube and sleeved outside the negative electrode tube. It is characterized in that the top of the positive electrode tube is provided with a spray device for washing the inner surface of the positive electrode tube
