Description

Technical Field

[0001] The utility model specifically relates to the technical field of heat recovery and waste gas collection and treatment of printing and dyeing, and specifically relates to heat recovery and collection and treatment equipment for textile printing and dyeing waste gas. Background Art

[0002] When the printing and dyeing equipment is used to dye textile fabrics, the fabrics need to be heated. In this way, the equipment will generate a large amount of heat during printing and dyeing. The recovery efficiency of traditional heat recovery devices is low, so a large amount of heat will be discharged into the air, which will cause heat waste. At the same time, a large amount of heat will also cause varying degrees of pollution to the environment.

[0003] After searching, CN202021042382.1 discloses an environmentally friendly heat recovery device; it includes a bottom plate, on the top of which a filter box, a fan, a heat exchange box and a sterilization box are fixedly installed from left to right in sequence, the inner cavity of the heat exchange box is provided with a heat exchange pipe, the inner side of the heat exchange pipe is fixedly connected with a separator, the inner wall of the heat exchange pipe is fixedly connected with a plurality of dispersion rods, the heat exchange box and the sterilization box are connected with a connecting pipe, the right end of the connecting pipe is connected with a ventilation plate, and the lower end of the inner cavity of the sterilization box is injected with an alkaline solution. The utility model works through the filter box, fan, heat exchange pipe, separator, dispersion rod, connecting pipe, ventilation plate, alkaline solution, ozone generator and ultraviolet sterilization lamp;

[0004] When the heat recovery device in the above patent recovers heat, it first filters and adsorbs the gas through the HEPA filter layer and the activated carbon filter layer. In this way, a large amount of heat in the gas will be consumed during filtration, and then transferred to the heat exchange pipeline through the fan. The thermal energy is greatly reduced, and the heat in the gas cannot be effectively recovered. When it is necessary to exchange heat with the water in the heat exchange pipeline, more gas is required for transportation, and the gas and water in the above patent are merged in the heat exchange pipeline, so the separation effect cannot be easily achieved, which will affect the efficiency of exhaust gas discharge.

[0005] Therefore, we provide a heat recovery and collection and treatment device for textile printing and dyeing waste gas. In this device, the gas with heat is transmitted to the inside of the box, and the heat in the waste gas is transmitted to the water inside the box, so as to realize the exchange of heat in the waste gas. After the heat exchange is completed, the waste gas is transported to the filter component through the gas pipeline installed on the box, so as to realize centralized treatment of the waste gas. The activated carbon installed in the filter component can effectively absorb the harmful impurities in the waste gas, so as to ensure that the prepared gas is non-toxic and harmless. In this device, a filter layer is also arranged inside the box, so that when in use, the impurities in water and air can be effectively filtered. Utility Model Content
