Production equipment heat recovery humidity control module and heat recovery humidity control system using same

Abstract

The invention relates to a production equipment heat recovery humidity control module and a heat recovery humidity control system applying the module, the heat recovery humidity control module is provided with an adsorption dehumidification rotating wheel at a fresh air inlet, moisture in outdoor fresh air in an adsorption area of the adsorption dehumidification rotating wheel is used for adsorption, moisture in the outdoor fresh air can be removed to a large extent, and the moisture in the outdoor fresh air can be removed to a large extent. The influence of air humidity changes caused by seasonal changes on the coating production speed and the product quality is reduced, the adsorption dehumidification rotating wheel is not provided with an additional regeneration heater, and part of high-temperature gas exhausted into the drying oven directly acts on a regeneration area of the adsorption dehumidification rotating wheel so that water vapor adsorbed on the rotating wheel can be desorbed and regenerated to the outside air. The system energy consumption is further reduced; in addition, heat exchange is carried out on external low-temperature fresh air and high-temperature gas in the production equipment through the heat exchanger, the external low-temperature fresh air is heated to be close to be guided into the drying oven, and therefore the system does not need to be provided with a fresh air heater, and energy consumption of the system is greatly reduced.

Description

technical field [0001] The invention relates to a heat recovery and humidity control module of production equipment and a heat recovery and humidity control system using the module, in particular to a modular processing scheme for realizing energy-saving and constant humidity adjustment of production equipment by combining a dehumidification wheel and a heat exchanger. Background technique [0002] In the production process of battery anode electrode sheet coating, the drying of the anode electrode sheet is one of the key processes. The drying process requires high energy consumption due to the need to heat the external fresh air to the specified drying temperature. figure 1 Shown is the high energy consumption solution of the existing coating machine oven 100, in which a heat exchanger 201 is provided, and the heat exchanger 201 can exchange the high-temperature exhaust gas inside the coating machine oven 100 with the fresh air sent in from the outside. Heat exchange, so th...

Problems solved by technology

[0003] However, this solution also has the following defects: (1) The air sent to the oven is the outdoor fresh air passing through the heat exchanger, and the humidity is relatively high, which cannot meet the requirements of a low dew point dry environment; (2) The humidity of the air supply varies with time and seasons. The change is large, and it is easy to affect the production speed and product quality of coating; (3) In order to be able to remove the moisture generated by the oven in the weather (season) with high humidity outside the air, it is necessary to increase the air supply and exhaust Air volume, which will in turn increase the energy consumption of the coating machine and greatly increase the operating cost
