New description: [New technical field] This is a volatile organic waste gas treatment device for coating process, especially a volatile organic waste gas which is released from the normal temperature process zone. The gas is cleaned and discharged, and the concentrated volatile organic waste gas is desorbed into the volatile organic waste gas generated in the high temperature process zone, and then the final, processing unit purifies the emission designer. _ [Prior Art] According to Volium le Organic Compounds (VOCs), sources can be divided into anthropogenic sources and natural sources, while anthropogenic sources are mostly derived from organic solvents used in industrial processes, but There are quite a lot of industries and complex types of VOCs in the process. The organic solvent components and ratios used in different industries and processes are quite different. The VOCs in the industry also have many differences in exhaust gas characteristics, and VOCs are treated under high temperature or normal temperature processes. It will volatilize, but since many of the coating process's normal temperature process is an open process, it is the main source of fugitive VOCs. # Next, for some industries where high-temperature process will produce high concentration and the normal temperature process may escape low-concentration and high-volume volatile organic waste gas, a simple process description will be given: '1. PU synthetic leather industry: PU (polyurethane) Formate) - Synthetic leather process is divided into dry and wet, dry process can be divided into transfer method and coating method, while wet process has impregnation method and coating method, taking dry transfer process as an example. The PU synthetic skin is prepared by dissolving the PU resin in an organic solvent, applying it to the release paper at room temperature, and drying the PU resin on the release M367027 paper to form a skin layer, and then using the adhesive to laminate the base fabric with the adhesive. After the skin is laminated and then processed by the "way drying process", the mineralized release paper is the finished PU synthetic skin. Second, the tape industry: the tape process mainly uses acrylic resin and rubber in an organic solvent to be diluted at room temperature and then coated on different substrates (such as 〇pp, PVC, PE, cloth, composite materials and cellophane, etc.) Above, it is heated by an oven for baking, and the organic solvent is evaporated, the resin is dried to form a skin layer and completely adhered to the base fabric, and then processed, and cut to obtain a finished product. Second, the backlight board industry: the process of the backlight board is to mix the adhesive with an organic solvent at normal temperature, and is applied to the light guide plate, and then the functional optical film of the rural layer is adhered to the light guide plate, and the adhesive is cured by heating. Made into finished products. 4. Coating industry: The coating process applies a coating containing an organic solvent to the coating at room temperature, and then is baked and baked by heating. V. Printing industry: Process pollution sources include ink dilution adjustment and printing at normal temperature, and drying at high temperatures. However, the coating process generally only processes volatile organic waste gas in a high-temperature process, and the volatile organic waste gas generated by a normal temperature process (such as mixing, painting, coating, ink dilution, and P brush) has a relatively low temperature process. Many, so the volatile organic waste gas that is escaping from the normal temperature process is generally not treated. 'But many of the coating processes are open-process processes, and if they are not effectively collected, they become fugitive volatile organic compounds. The main source of exhaust gas' and the volatile organic waste gas emitted by the 2-temperature process are high air volume and low concentration. If the gas is to be collected and then incinerated, the upper part of the incineration must be adopted because of the high air volume and low spread. The final processing equipment of the capacity and the consumption of more fuel (energy) can be incinerated. M367027 [New Content] The main purpose of this creation is to solve the problem that the prior art does not collect the volatile organic waste gas that has been dispersed in the normal temperature process of the coating process, and collects and purifies the concentrated process. The volatile organic waste gas dispersed in the normal temperature process is concentrated, and then purified together with the volatile organic waste gas generated by the high temperature process, and the effect of reducing the capacity of the final treatment equipment is achieved.

In addition, the concentration unit (Concentrator) is a Rotor type rotary concentrator, a Carousel type rotary concentrator or a fluidized bed concentrator; wherein the rotary wheel type The concentration ratio of the concentrator and the rotary concentrator can be 5 to 30 times, and preferably 8 to 15 times; the concentration ratio of the fluidized bed concentrator can be 50 to 10000 times, and 100 to 1000 times. It is better. Moreover, the final treatment unit is a condenser or an incinerator; when the final treatment unit is an incinerator, the heat of incineration is used to provide the desorption heat required for the concentration unit; and the incinerator is a double tank type thermal storage incinerator, Multi-tank thermal storage incinerator, rotary thermal storage incinerator, direct-fired incineration M367027 furnace or catalytic incinerator. In addition, the normal temperature process area is one of a mixing zone, a paint adjustment zone, a coating zone, an ink dilution zone and a printing zone of a general room temperature of 5 to 45 ° C, or a combination thereof, and the high temperature process zone is 60 to 15 (rc 【Examples】 First, please refer to the first figure.
