Description

Technical Field

[0001] The utility model belongs to the technical field of drying, and in particular relates to a drying device capable of regenerating exhaust gas treatment. Background Art

[0002] Drying devices are used in the processing of various materials. Drying devices generally include drying cylinders and dehumidifying cylinders. Dry air is heated by a drying heater and transported to the material drying cylinder to heat and dry the material. The air that has absorbed moisture from the material is discharged from the drying cylinder and enters the dehumidifying cylinder. The hygroscopic particles in the dehumidifying cylinder absorb moisture from the air to obtain low dew point air, which is then heated and sent back to the drying cylinder. The regenerated air is heated by a regeneration heater and transported to the dehumidifying cylinder to discharge moisture from the hygroscopic particles. The regenerated air is directly discharged into the atmosphere.

[0003] In this process, the dust particles in the material will be discharged into the atmosphere through the drying hot air → dehumidification cylinder → regeneration hot air. Especially for materials containing glass fiber, the dust particles will cause great harm to the human body and the environment. Moreover, the dust particles are small and it is difficult to completely clean them up by adding filters.

[0004] To deal with the regeneration exhaust gas of the dryer, most companies currently install an exhaust gas recovery system, and the regeneration exhaust port of each dryer is connected to the exhaust gas recovery pipeline.

[0005] The exhaust recovery system has high investment costs and involves the installation of exhaust pipes. It also limits the installation space of the factory. Some old factories have difficulty in adapting to this system. It is suitable for factories that centrally place a large number of dryers. When there are few dryers or they are scattered, the investment and operation costs of centralized exhaust recovery are high. In addition, the dryer is connected to the recovery pipe by hardware. When the factory changes the production product and causes the dryer to move, the connecting pipe needs to be removed again, which is a lot of work and wastes manpower. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure flow of the drying device for regenerable exhaust gas treatment of the utility model. DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0015] like Figure 1 The figure shows a specific embodiment of the drying device for regenerable exhaust gas treatment of the utility model. The drying device comprises a drying barrel 1 and a dehumidifying barrel 3, and a drying path and a regeneration path are provided between the drying barrel 1 and the dehumidifying barrel 3. Specifically, the drying device comprises a drying heater 2 and a drying fan 8, and the outlet of the drying barrel 1, the drying fan 8, the dehumidifying barrel 3, the drying heater 2, and the inlet of the drying barrel 1 are sequentially connected to form the drying path. The drying device comprises a regeneration fan 9 and a regeneration heater 4, and the regeneration fan 9, the regeneration heater 4, and the dehumidifying barrel 3 are sequentially connected to form the regeneration path.

[0016] The regeneration exhaust outlet of the dehumidification cylinder 3 is provided with a regeneration exhaust processing unit, and the regeneration exhaust processing unit includes a water storage cylinder 6 and an exhaust pipe. One end of the exhaust pipe is connected to the regeneration exhaust outlet, and the other end of the exhaust pipe is arranged below the water surface in the water storage cylinder 6. The water storage cylinder 6 is provided with an exhaust port, and the exhaust pipe is provided with a check valve 5.

[0017] Before the regenerated exhaust gas of the dehumidifying cylinder 3 is discharged into the atmosphere, it is first sent to the water storage cylinder 6 through the exhaust pipe. The water in the water storage cylinder 6 is used to absorb all the dust particles in the regenerated exhaust gas and store the dust particles in the water storage cylinder 6, thereby achieving the function of purifying and removing the dust particles in the exhaust gas and avoiding the regenerated exhaust gas from polluting the environment. On the other hand, the regenerated exhaust gas has a high temperature and directly discharged into the atmosphere, which will increase the ambient temperature of the factory workshop as a heat source; through the regenerated exhaust gas processing unit of the utility model, the regenerated hot exhaust gas is discharged into the atmosphere through the water in the water storage cylinder 6, which can achieve the effect of cooling the exhaust gas.

[0018] In addition, in order to prevent water vapor from the water storage tank 6 from entering the dehumidification cylinder 3 when the machine is shut down, a check valve 5 is installed in the exhaust pipe so that it is opened in one direction when the machine is running and automatically mechanically resets and closes when the machine is shut down, thereby blocking water vapor from entering the dehumidification cylinder and ensuring the dehumidification effect of the dehumidification cylinder.

[0019] The water storage cylinder 6 is provided with a water level switch 7 to detect the water level in the water storage cylinder. When a low water level is detected, a water shortage alarm is issued to prompt the user to add water.

[0020] The water storage cylinder 6 is provided with a buckle fixed cover, which can be conveniently removed for cleaning operation. A water storage cylinder cleaning prompt function can be set, and after the set time is reached, the water storage cylinder cleaning operation is prompted to ensure the dust removal effect.

[0021] The beneficial effect of the drying device with regenerative exhaust gas treatment of the utility model is that there is no need for the factory to install a regenerative exhaust gas recovery system, no need for pipeline connection, and only one regenerative exhaust gas treatment unit is required for each dryer. The regenerative exhaust gas treatment unit has a simple structure, is easy to clean and maintain, and has a low cost, which greatly reduces the factory's investment capital and operating costs.

[0022] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
