Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0018] Such as Figure 1-2 Described a kind of NMP filter comprises waste gas pipe 1, cooling pipe 2, separation pipe 3 and exhaust elbow 4, and one end of waste gas pipe 1 is connected with waste gas discharge equipment, and waste gas discharge equipment discharges the mixed gas containing NMP into waste gas Tube 1. The cooling pipe 2 is sleeved and fixed on the exhaust pipe 1, a cooling channel 5 is formed between the cooling pipe 2 and the exhaust pipe 1, and a cold air inlet 6 and a cold air outlet 7 are respectively provided on the cooling pipe 2 The cold air outlet 7 is provided with a muffler 8, and the cold air in the cooling channel 5 is finally discharged from the cold air outlet 7. The addition of the muffler 8 can reduce the noise generated when the cold air is continuously flowing, thereby providing a quiet working environ...

Abstract

The invention mainly discloses a NMP filter. According to a technical scheme in the invention, the NMP filter comprises an exhaust gas pipe, a cooling pipe, a separation pipe and an exhaust elbow, wherein the cooling pipe sleeves and is fixed on the exhaust gas pipe; a cooling channel is formed between the cooling pipe and the exhaust gas pipe; the separation pipe is communicated with the exhaust gas pipe and fixedly connected with the exhaust elbow; one end of the exhaust elbow extends out of the separation pipe, and the other end of the exhaust elbow is located in the separation pipe; the bottom of the separation pipe is provided with a drain outlet; the cooling pipe is separately provided with a cold air inlet and a cold air outlet; and the cold air inlet is connected with a vortex tube. The NMP filter provided by the invention is simple in structure, condenses NMP gas in exhaust gas into liquid through low-temperature cooling, and realizes gas-liquid separation and exhaust gas emission without pollution.

Description

technical field [0001] The invention relates to the technical field of NMP gas treatment, in particular to an NMP filter. Background technique [0002] During the production process of lithium batteries, waste gas containing NMP gas will be generated. This waste gas does not meet the air emission standards, and direct external discharge will pollute the atmosphere. NMP gas treatment generally adopts cooling water or spray recovery, which has a large amount of water and high energy consumption, and a serious waste of resources. If recovery treatment equipment is used, the cost will increase and the economic benefit will decrease. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an NMP filter with a simple structure, which condenses the NMP gas in the waste gas into liquid through low-temperature cooling, realizes gas-liquid separation, and has no pollution in tail gas discharge. [0004] In order to achieve the ...
