Description
Technical Field
The utility model relates to a cigarette factory auxiliary air conditioning technical field, concretely relates to multi-purpose auxiliary air conditioning system of cold and hot dehumidification of cigarette factory.
Background
In cigarette production, the storage of cigarette raw materials and tobacco leaves, the shredding, the storage, the cigarette manufacturing, the finished product storage and the like are closely related to the environmental temperature and humidity. The air-conditioning service area of the cigarette factory includes: a tobacco shred making workshop, a raw tobacco stacking workshop, a stem storage cabinet, a leaf storage cabinet, a stem storage cabinet, a blending and flavoring workshop, a tobacco shred storage room and a rolling and wrapping workshop. The production practice of cigarette factories proves that the production combined air conditioning system has the following defects: when refrigerating, the cold source is provided by the refrigerator of the power station; when heating, the steam is provided by the power station. Because the refrigerator does not have a cold and heat source, the refrigerator cannot provide refrigeration, heating, dehumidification and other services in a transition season (when the refrigerator is stopped, the outdoor environment temperature and humidity are suddenly high and suddenly low). Particularly, in the south area of the yellow river, the performance is particularly obvious when the temperature difference and the humidity difference are large in transition seasons, the temperature is high in summer and the humidity is large: when the refrigerator is not started, the temperature is slightly high, the humidity is high, and dehumidification cannot be realized; when the refrigerator is started, the operation cost is high, the demand is small, and the temperature and humidity difference is large at night in the daytime and before and after rain in most of the time.
In the south of the Yangtze river, the temperature of cooling water of a refrigerating machine in a refrigerating station is high and high in summer, the national standard is 32-38 ℃, a cooling tower cools the rest part of water by evaporating water, and the temperature of the cooling water cannot be reduced, so that the refrigerating capacity and the refrigerating efficiency of the refrigerating machine are greatly reduced when the refrigerating machine operates in summer, even refrigeration is not performed, the production safety and the cigarette quality are seriously influenced, and some cigarette factories even have to stop production. When the plum rain season comes in the south of the Yangtze river (such as the rainy seasons in the areas of Hubei, Hunan, Jiangxi, Fujian, Zhejiang, Jiangsu, Sichuan and Liangguang), the environmental temperature meets the production standard, but the humidity reaches more than 90 percent or even is saturated, and when the refrigeration mode is started for dehumidification, the temperature of a workshop is greatly reduced, so that the situation that the temperature is lost and the product quality is seriously influenced is solved.
The climate characteristics of the cloud and precious region are more distinct: the temperature is higher in winter (than in the north) and is slightly lower in summer (than in the south of the Yangtze river); the altitude causes lower air humidity and large day and night temperature difference all the year round. Taking transition seasons (spring and summer and autumn) as an example, the temperature is proper at night, the temperature is high in the daytime, and refrigeration is needed in the daytime, but at the moment, the refrigeration system is not started for the time specified by the state (5-8-15 months, or just after the refrigeration season), and the refrigeration requirement cannot be provided; and in summer, the weather is hot in the daytime, and if the refrigerating capacity of the matched refrigerating system is small, the refrigerating requirement cannot be met. In the transition season, the winter-spring crossing and the autumn-winter crossing have proper daytime temperature and lower night temperature, and partial auxiliary heating needs to be provided at night, but the heating start time (11 months and 15 days or 3 months and 15 days just after the heating) specified by the state is not reached at the moment, and the heating demand cannot be provided.
