[0026] Fiber-reinforced composite materials made of ultra-high molecular weight polyethylene fibers have the advantages of light weight, impact resistance, and high dielectric properties. They are widely used in the fields of aerospace, maritime defense, weapons and equipment, and daily industry. In the production process of ultra-high molecular weight polyethylene fiber cloths, some additives containing gasoline, diesel, kerosene and other mineral oils are often used as lubricants or solvents, which causes the ultra-high molecular weight polyethylene fiber cloths to produce odorous gases during the production process, and the odorous gases need to be purified in a timely manner.

[0046] When the deodorizing device for ultra-high molecular weight polyethylene fiber cloth production is actually used, the intake manifold 4 is connected to the exhaust gas outlet of the ultra-high molecular weight polyethylene fiber cloth production equipment through a pipeline, so that the exhaust gas containing volatile organic compounds enters the deodorizing chamber 3 located at the front side through the intake manifold 4, the transverse pipe 18 and the front intake branch pipe 19 (at this time, the electronic control valve 20 on the rear intake branch pipe 19 is in a closed state, the rear deodorizing chamber 3 is in an idle state, and the front and rear two groups of deodorizing chambers 3 are used in turn. When one group of deodorizing chambers 3 is performing normal deodorizing work, the other group of deodorizing chambers 3 can be subjected to corresponding maintenance and repair work), and multi-stage coordinated purification is performed. The specific process is as follows:
[0047] Pretreatment stage (function of guide aluminum plate array 6):
[0048] After the exhaust gas containing volatile organic compounds enters the deodorization chamber 3, it first passes through the inclined and staggered guide aluminum plate array 6, and the staggered distribution design structure is used to extend the airflow path (increase the contact time by about 30%). When the solvent vapor in the exhaust gas is cooled to its saturation temperature (dew point), it begins to condense from gas to liquid. After cooling, the condensate generated slides down the inclined aluminum plate 601 and flows into the solvent recovery box 26 through the guide groove 25, thereby cooling the exhaust gas, reducing the subsequent filtration load, and realizing solvent recovery, saving costs;
[0049] Physical interception stage (bag filter 8 function):
[0050] The exhaust gas passing through the guide aluminum plate array 6 continues to flow to the right and passes through the bag filter 8 on the support plate 7, wherein the fiber dust and fine particles are intercepted by the bag filter 8;
[0051] Chemical adsorption stage (activated carbon filter plate 10 function):
[0052] The exhaust gas passing through the bag filter 8 continues to flow to the right, passing through the activated carbon filter plate 10 mounted on the mounting frame 9, and the polar VOCs such as benzene series and sulfide in the exhaust gas are adsorbed by the activated carbon filter plate 10;
[0053] Liquid phase reaction stage (action of atomizing nozzle 12):
[0054] The exhaust gas passing through the activated carbon filter plate 10 continues to flow to the right, and the flocculation liquid is injected into the spray pipe 11 by using the flocculation liquid storage box 13, and the flocculation liquid containing sodium hypochlorite or hydrogen peroxide is sprayed by using the atomizing nozzle 12, so that the flocculation liquid mist reacts with the aldehydes and ketones in the exhaust gas to remove the particulate matter and gaseous pollutants in the exhaust gas;
[0055] Deep decomposition stage (UV photolysis unit 16 function):
[0056] The exhaust gas passing through the spray pipe 11 continues to flow to the right, and after being evenly diverted by the diverter plate 15, it is irradiated by the UV photolysis unit 16 to decompose the organic or inorganic high molecular compounds into low molecular compounds, remove the odor, and finally discharged to the outside from the outlet branch pipe 5, completing the deodorization work for the entire ultra-high molecular weight polyethylene fiber cloth production.
