Description

一种烟草育苗与烟叶烘烤联合供热系统 A tobacco seedlings and tobacco curing joint heating system

技术领域 FIELD

[0001] 本发明属于烟草育苗及烟叶烤制设施技术领域,更具体地,涉及一种烟草育苗与烟叶烘烤联合供热系统。 [0001] The present invention pertains to the tobacco and tobacco seedling baking facilities technology, and more particularly, to a combined flue-cured tobacco and tobacco seedling heating system.

背景技术 Background technique

[0002] 在烟叶生产过程中,烟草育苗及烟叶烘烤是两个十分重要的环节。 [0002] In the process of tobacco production, tobacco seedlings and tobacco curing are two very important aspects. 烟草育苗以培育出适期、适龄、无病、健壮、形状大小适宜的烟苗为目的,其对整个烟草生产过程顺利完成起着关键作用。 Tobacco seedlings cultivated in suitable period, age, disease-free, robust, Tobacco suitable shape and size for the purpose, which plays a key role in the overall tobacco producing process is completed successfully. 烟草育苗技术按照覆盖方式分为:大棚育苗、小拱棚育苗以及陆地育苗三大类,而按照育苗营养体则分为:育苗盘育苗、营养钵育苗、营养池育苗以及营养袋育苗四大类。 Tobacco breeding techniques so as to cover divided into: greenhouse nursery, Small Shed nursery and nursery land three categories, and in accordance with the vegetative nursery is divided into: nursery seedling tray, seedling raising, nutrition Ponds and nutrition bag nursery four categories. 现代农业以集约化、节约化以及工业化生产为宗旨,所以就烟草育苗来说,现代化的温室大棚育苗已成为主流趋势,其相对于小拱棚育苗以及陆地育苗来说有着多方面的优越性,最主要的两点就是:集约化与可调控性。 Modern intensive agriculture in order to save for the purpose of industrial production and so on tobacco breeding, the modern greenhouse nursery has become a mainstream trend, with respect to Small Shed nursery and nursery land, it has many advantages, the most the main points is this: intensive and regulatory available. 目前,育苗大棚内多采用营养液浮盘育苗方式,·即在育苗大棚内整齐排列若干个育苗池,池内注入一定高度的营养液,多个育苗浮盘漂浮于育苗液之上的育苗方式,本专利也主要针对这一育苗方式。 Currently, the use of multi-nutrient solution nursery greenhouses Seedling floating disc, a plurality of alignment · i.e. in nursery greenhouses breeding pools, tanks nutrient solution into a certain height, a plurality of seedling floating disc floating on top of each seedling nursery solution, this patent also focused on the breeding method. 烟叶烘烤过程及工艺直接决定了烟叶的质量,目前国内应用最广的烤烟技术为密集烤房烤烟技术,它是实施“烟草现代农业”的基础。 Tobacco curing process and the process will determine the quality of tobacco, currently the most widely used technology for the flue-cured tobacco flue-cured tobacco barn-intensive technology, it is the foundation "of modern tobacco agriculture". 密集烤房的推广应用,提高了我国烟叶烘烤水平,对提高户均种烟面积,逐步形成集约化种植和专业化烘烤,起到了明显促进作用。 Promote the use of bulk curing barn, raise the level of flue-cured tobacco, to improve the average kinds of tobacco area, and gradually form of intensive farming and specialized curing, played a significant role in promoting. 但是随着烟草农业的发展,现有密集烤房在许多方面都显得不尽如人意,主要缺点包括:1、每座烤房都配有一座热风炉,都需要配一位司炉工,因而提高了建设成本和人工成本;2、烤房温度控制方法单一,因而温度控制精度不高;3、燃煤污染物无法集中控制,所以对环境造成的污染较大。 But with the development of tobacco farming, existing bulk curing barn are obviously not satisfactory in many respects, the main drawbacks include: 1, each seat is equipped with a stove barn, with a fireman needs, thus increasing labor costs and construction costs; 2, barn temperature control of a single method, and thus the temperature control accuracy is not high; 3, coal can not be centrally controlled pollutants, the environmental pollution caused by large. 针对以上提到的一些缺点,集中供热密集型烤房成为了现今的一个发展热点,它能很好的解决现有密集烤房存在的一些问题,是密集型烤房发展的一个新方向。 For some of the disadvantages mentioned above, central heating intensive barn has become a development hot spot today, it is a good solution to some problems existing bulk curing barn, the barn is a new direction for intensive development.

[0003] 由于烟草育苗大棚布置在室外,所以育苗温度由外界环境温度决定,而在有些地区,春季育苗期间外界温度都比较低,通常都在10°C以下,这将对烟苗的生长周期产生很大的影响。 [0003] Since the tobacco nursery greenhouses arranged outdoors, so the nursery temperature is determined by the ambient temperature, but in some areas, outside temperature during the spring seedlings are relatively low, usually at below 10 ° C, which would have the growth cycle of tobacco seedlings have a huge impact. 烟草种子萌发需要适宜的温度,一般以25°C〜28°C为宜,最低11°C〜12°C,最高30°C。 Tobacco seed germination requires suitable temperature, generally 25 ° C~28 ° C is appropriate, a minimum 11 ° C~12 ° C, up to 30 ° C. 在28°C〜30°C条件下,发芽快,但不整齐;超过30°C发芽减慢,超过35°C种子失去生活力;若低于12°C,则萌动迟缓,过低将发生冻害。 Under conditions of 28 ° C~30 ° C, germinate fast, but irregular; More than 30 ° C germination rate, exceed 35 ° C seeds lose viability; if less than 12 ° C, then slowly germinating, will occur too low frost damage. 鉴于以上各因素,为了提高烟苗存活率,缩短烟苗生长周期,提高烟苗生长质量,需要在育苗大棚内加装供暖设备。 In view of the above factors, in order to improve the survival rate of tobacco seedlings, shorten the seedling growth cycle and improve the quality of seedling growth, the need to install the heating apparatus in nursery greenhouses. 目前,国内外应用的大棚供暖技术主要包括:热风炉供暖、电加热管供暖、热泵供暖以及一种新型的热水管道系统供暖。 Currently, greenhouse heating technology abroad applications include: heating stove, electric heating tube heating, heat pump heating and hot water piping system, a new heating. I、热风炉供暖,即利用燃煤或者燃气热风炉通过在换热罩内换热加热大棚内的空气;2、电加热管供暖,即利用电加热管通电时散发的热量加热大棚内的空气;3、热泵供暖,即利用热泵工作时产生的热量加热大棚内的空气;4、热水管道系统供暖,即通过在大棚内布置若干热水管道,通过管道内流动的热水加热大棚内的空气,其热源一般为常压热水锅炉。 I, stove heating, i.e., using coal or gas stove through the air in the heat exchanger is heated in the heat exchanger cover greenhouses; 2, the electrical heating tube heating, i.e., using heated air in the greenhouse heat emitted during energizing the electric heating tube ; 3, heat pump heating, greenhouse heating air in the heat generated by the heat pump working ie; 4, hot-water heating piping system, i.e., by arranging a plurality of water pipes in the greenhouse, the greenhouse is heated by the hot water flowing inside the pipe air pressure which the heat source is generally hot water boiler. 它们的特征都是直接加热大棚内空气,这类方式对于常规的大棚供暖效果很好,但是对于营养液浮盘育苗大棚的供暖效果就不明显,因为被加热空气的热量很难穿过浮盘到达营养液,从而很难为烟苗根部供暖。 They are characterized by the greenhouse air are directly heated, such a conventional manner for greenhouse heating effect very good, but the heating effect is not apparent to the floating disc nursery greenhouses nutrient solution, because heat is hard to pass through the heated air floating disc reaches the nutrient solution, making it difficult for the heating Tobacco root. 在烟叶烘烤与烟草育苗联合供热系统中,涵盖了一种新型的大棚供暖方式,可以很好的解决这一问题。 In tobacco curing tobacco seedlings joint heating system, covering a new greenhouse heating method, we can solve this problem.

[0004] 集中供热密集型烤房相对于传统的密集型烤房有着诸多变化:1、由于集中供热设备为整个烤房群供热,所以不像传统单座密集烤房一样安装在装烟室相连的热风室内,而是单独置于烤房外;2、为将供热设备产生的蒸汽、热烟气等供应到每一座烤房,需要从供热设备出口至每一烤房设计安装统一的供热管网;3、在每座密集烤房室内不再设置加热炉及鼓风机;4、为使每一座烤房位置各自独立的烘烤工艺(因为各烤房的烟叶品质、数量、含水量、成熟度等均有差别),确保烘烤质量,每一座烤房仍需保留循环风机、进风门、排湿窗、控制仪等。 [0004] with respect to the central heating barn-intensive traditional intensive barn with many changes: 1, since the central heating system for the entire population of heating the barn, so unlike conventional single seat mounted in the same package Curing Barn hot air chamber connected to the smoke chamber, but placed outside the barn alone; 2, steam, hot flue gas or the like is supplied to the heating device generates each of a barn, the device needs to exit from heating to design each barn uniform heating network installation; 3, and the furnace blower is no longer set in each block bulk curing barn interior; 4, a barn to make each position independently of the baking process (because of the quality of tobacco in each barn, the number of , water content, and maturity were different), to ensure the quality of baking, each barn still retains a circulating fan, into the throttle, humidity and window control instrument. 在供热设备选择方面,包括:热水锅炉、蒸汽锅炉、导热油锅炉以及热风炉,它们各有优缺点:1、热水锅炉运行温度低,安全性好,价格便宜,但换热媒介的温度(85-95°C)较低,在达到相同的供热负荷前提下,必须加大换热面积,换热器成本明显增加,各烤房的热负荷分配不易十分均匀热水锅炉必须使用循环水泵,电耗增加;2、蒸汽锅炉供热效率高,蒸汽参数稳定,烤房热负荷分配可达到较为均匀,蒸汽锅炉对司炉工要求高,对运行维护要求较高;3、导热油锅炉需要运行一段时间后更换导热油,运行成本高;4、热风炉换热过后的热空气洁净无污染不会对管道和散热器产生积灰,但换热系数较低,供热负荷变化时的可调节性较差。 The choice of heating equipment, including: hot water boiler, steam boiler, oil boiler and hot stove, they have advantages and disadvantages: 1, low temperature hot water boiler operation, security is good, the price is cheap, but the heat transfer medium temperature (85-95 ° C) lower, the heat load to achieve the same premise, it is necessary to increase the heat transfer area, significantly increase the cost of the heat exchanger, the heat load is very difficult to assign each barn uniformly hot water boiler must be used circulating pumps, the power consumption increases; 2, high heating efficiency of the steam boiler, steam parameters stable, barn heat load distribution can be achieved more evenly, boiler steam requirements for fireman high, high operation and maintenance requirements; 3, oil boiler after a period of operation required to replace conducting oil, high operating costs; 4, hot air from contamination after the air heat no fouling of the pipe and the radiator, but the low heat transfer coefficient, the heating load changes poor adjustability.
