Description

Technical Field

[0001] The utility model belongs to the technical field of purification devices, in particular to a volatile organic matter purification device. Background Art

[0002] The purification of volatile organic waste gas is very important for protecting the environment. During the purification of volatile organic waste gas, it is sometimes necessary to incinerate the waste gas. The existing waste gas incineration device is large in size, and the waste gas passes through the waste gas incineration device quickly and then is output, so that the organic waste gas passes through in a short time and there may be a problem of insufficient incineration treatment. After searching, the patent with application number 201720531178.8 discloses a volatile organic compound re-purification device, and particularly relates to a volatile organic compound re-purification device, including a waste gas incineration device, wherein two groups of bearing groups are arranged on the top and bottom of the inner side wall of the waste gas incineration device, and the bearing groups arranged on the top and bottom of the inner side wall of the waste gas incineration device are staggered. The bearing group is composed of two symmetrically arranged bearings, and the inner ring of the bearing is fixedly arranged on the inner side wall of the waste gas incineration device. The outer side wall of the outer ring of the bearing is evenly distributed with gear blocks. The outer rings of the bearings in the same group are connected by a cross bar. The top plate and the bottom plate of the waste gas incineration device are provided with strip-shaped slots, and a motor is installed in the slot. The motor is connected to a spiral shaft, and the spiral pattern of the spiral shaft is in meshing contact with the gear blocks. A baffle is arranged on the cross bar.

[0003] However, during actual use, the applicant found that by setting a baffle to extend the exhaust gas channel inside the exhaust gas incineration device, the incineration effect of volatile organic waste gas was improved, but some volatile organic waste gas would directly pass through the gap between the rotating cross bar and the exhaust gas incineration device, which is not conducive to the full incineration and purification of the volatile organic waste gas. In view of this, we propose a volatile organic matter purification device. Utility Model Content

A first gas injection nozzle 73 is fixedly provided at the bottom of the incineration slot 71, and an air intake branch of the first gas injection nozzle 73 extends to the outside of the purification box 1. The volatile organic waste gas passing through the incineration slot 71 can be incinerated by the first air injection nozzle 72 and the first gas injection nozzle 73. An exhaust pipe 4 is fixedly provided on the rear side of the convergence cover 3. The waste gas after incineration treatment can be discharged through the exhaust pipe 4. When the volatile organic waste gas is incinerated, the volatile organic waste gas can be introduced into the intake pipe 2.
