Description

Ozone collecting and decomposing device for integrated film blowing corona machine Technical Field The utility model relates to an integrated ozone collecting and decomposing device for a film blowing corona machine, and belongs to the technical field of ozone collecting and decomposing devices. Background Corona treatment machine is commonly called corona machine, and is mainly used for surface treatment of plastic film or plastic plate product so as to make the above-mentioned materials implement the operations of printing ink, compounding, blowing film, coating, cementing, material modification, grafting, polymerization, film-plating, casting and sticking, etc.. Corona machine works on the principle that high voltage is used to generate low temperature plasma on the surface of plastic to be treated through corona discharge, so that free radical reaction is generated on the surface of plastic to crosslink polymer. When a high voltage is applied between the electrodes of the corona machine, a corona discharge phenomenon occurs. Corona discharge is a partial discharge which mainly occurs in the gas near the electrode, and during the corona discharge process, high-energy electrons collide with oxygen molecules in the air to ionize the oxygen molecules. During ionization, the oxygen molecules (O 2) are decomposed into oxygen atoms (O), Oxygen atoms (O) generated by ionization react with surrounding oxygen molecules (O 2) to generate ozone (O 3). Because the air exchange in the production workshop can not meet the requirement of ozone diffusion far away, the ozone decomposed and diffused can not reach a certain concentration, and the environment and the human health can be possibly damaged. Thus, for ozone released by the corona machine, appropriate measures need to be taken for recovery and disposal. The existing ozone collection treatment device is generally suitable for collecting ozone of a single corona machine, and in a production workshop, the position of the corona machine is often arranged before production, the arrangement of the corona machine is compact, the ozone collection treatment device belongs to subsequent environment improvement equipment, the position of the device is not reserved at the beginning, and more manpower and material resources are wasted when the peripheral position of the single corona machine is designed and modified for placing the ozone collection treatment device. Therefore, the ozone generated by a plurality of corona machines needs to be collected and treated intensively. Disclosure of utility model The present utility model aims to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above. The technical scheme provided by the utility model is that the ozone collecting and decomposing device for the integrated film blowing corona machine comprises a corona treatment machine, an ozone decomposing box, a fan and a conveying pipeline, wherein the conveying pipeline sequentially connects the corona treatment machine, the fan and the ozone decomposing box; the conveying pipeline comprises a collecting pipeline and an air inlet pipeline, a plurality of corona treatment machines are arranged, each corona treatment machine is communicated with the collecting pipeline through the air inlet pipeline, and a valve is arranged on the air inlet pipeline. Compared with the prior art, the technical scheme has the advantages that ozone generated by the corona treatment machine in the working process sequentially passes through the air inlet pipeline and the collecting pipeline and enters the ozone decomposition box under the pressure effect of the fan, the corona treatment machines are respectively communicated with the air inlet pipeline and the collecting pipeline, and each corona treatment machine is different in distance from the fan, so that the suction force at the air inlet pipeline of each corona treatment machine is different, a valve is arranged on the air inlet pipeline, the air inlet size of the air inlet pipeline is changed to adjust the air speed through controlling the valve, the air quantity of each corona treatment machine is balanced, and ozone generated by equipment far away from the fan can be fed into ozone reaction equipment. On the basis of the technical scheme, the utility model can be improved as follows. Preferably, the fan is connected with the control box. The control box is used for adjusting the power of the fan, and when the corona treatment machines at different positions are working, the power of the fan is adjusted according to the distance from the fan so that enough suction force can be used for sucking ozone into the air inlet pipeline. Preferably, the collecting duct has a larger diameter than the inlet duct. The beneficial effect of adopting above-mentioned further scheme is, the ozone in many admission lines gathers in collecting the pipeline, is pressed to send to ozone decomposition i
