Description
技术领域 technical field
本发明属于粮食物流与储藏安全的技术领域，具体地说是一种粮库自驱动地冷循环与表面隔热系统。 The invention belongs to the technical field of grain logistics and storage safety, in particular to a self-driven cooling cycle and surface heat insulation system for a grain depot.
背景技术 Background technique
粮食是关系国民经济发展、社会和谐稳定的重要战略物资和特殊商品，粮食安全在国家经济安全中具有重要地位。各类粮库在承担国家和地方粮食储备任务中发挥着至关重要的作用。粮食的储藏品质与储藏温度、湿度密切相关。储备粮一般在15℃以下适宜储存，储藏温度过高，会造成粮食结露、发热生霉。然而在粮食长期储藏时，受光照的影响，多数粮库在午间及下午升温迅速，粮仓顶部和上部温度甚至可达40℃ ~ 50℃，粮食的安全储藏受到严重威胁，特别是如果将高水分粮食堆积在一起，极易升温、结顶和霉变，造成严重损失。 Grain is an important strategic material and special commodity related to the development of the national economy and social harmony and stability. Food security plays an important role in national economic security. All kinds of grain depots play a vital role in undertaking national and local grain reserve tasks. The storage quality of grain is closely related to storage temperature and humidity. Reserved grains are generally suitable for storage below 15°C. If the storage temperature is too high, it will cause grain condensation, heat and mold. However, in the long-term storage of grain, affected by the light, most grain depots heat up rapidly in the noon and afternoon, and the temperature on the top and upper part of the granary can even reach 40 ℃ ~ 50 ℃. The safe storage of grain is seriously threatened, especially if the high moisture Grain is piled up together, and it is very easy to heat up, form a roof and go moldy, causing serious losses.
因此，必须对粮库进行及时和适当的降温处理。传统的降温方法主要为空调降温法，以空调制冷降温一方面耗能严重，粮食生产企业设备采购和日常能耗负担增加；另一方面安装于粮库顶部的空调压缩机的震动会部分毁坏粮库，形成裂隙甚至裂缝，给粮食安全储藏带来更大隐患。 Therefore, it is necessary to timely and properly cool down the grain depot. The traditional cooling method is mainly the air-conditioning cooling method. On the one hand, air-conditioning cooling consumes a lot of energy, and the equipment purchase and daily energy consumption burden of grain production enterprises increases; on the other hand, the vibration of the air-conditioning compressor installed on the top of the grain depot will partially destroy the grain. Depots, forming cracks or even cracks, bring greater hidden dangers to food safety storage.

Improving the quality of grain storage in warehousing enterprises and reducing energy consumption has obvious economic and social benefits.
本发明的目的通过下述技术方案来实现： The purpose of the present invention is achieved through the following technical solutions:
一种粮库自驱动地冷循环与表面隔热系统，其特征在于：该系统包括设于粮库仓体地下的地冷设施、设于粮库仓体内壁的水流循环管道、设于粮库仓体顶壁的太阳能发电装置、设于粮库仓体外壁和顶壁的反光隔热涂层；所述太阳能发电装置中的地冷平板太阳能集热器安装在粮库仓体顶部，主朝向为207’SW ~ 247’SW方向；水流循环管道均设置在粮库仓体四壁的半空心墙体内，在155'SE ~ 265'SW方向，加密分布，水流循环管道由地冷管、套管，密封胶、防水材料增强层组成，进水和出水管道并行，并留有间隙。 A self-driven ground cooling cycle and surface heat insulation system for a grain depot, characterized in that the system includes ground cooling facilities installed underground in the grain depot, water circulation pipes disposed in the inner wall of the grain depot, The solar power generation device on the top wall of the warehouse body, the reflective heat insulation coating on the outer wall and top wall of the grain warehouse; the ground-cooled flat solar collector in the solar power generation device is installed on the top of the grain warehouse In the direction of 207'SW ~ 247'SW; the water circulation pipes are all set in the semi-hollow walls of the four walls of the grain depot, in the direction of 155'SE ~ 265'SW, densely distributed, the water circulation pipes are composed of ground cooling pipes, The sleeve is composed of sealant and waterproof material reinforcement layer, and the water inlet and outlet pipes are parallel with gaps.
本发明中，所述粮库仓体墙体为部分中空构造，中空构造彼此相连，水流循环管道安装在墙体中空内壁，不会增加粮仓内部湿度。系统运转时安静无震动，不会对粮库结构造成损坏。 In the present invention, the wall of the granary is partially hollow, and the hollow structures are connected to each other, and the water circulation pipe is installed on the hollow inner wall of the wall, which will not increase the humidity inside the granary. The system runs quietly and without vibration, and will not cause damage to the structure of the grain depot.
所述粮库仓体是高大平房仓和浅圆仓，不可应用于周转库的立桶仓型粮库。在粮库仓体外壁顶壁设有酚醛树脂发泡材料或玻璃纤维网格布保温层。反光隔热涂层位于90'E ~ 270'W方向范围内，且由日光热反射涂料或辐射散热降温涂料构成，确保冬季极冷条件下，墙体内温度在0℃以上。 The granary warehouse body is a tall flat warehouse and a shallow round warehouse, which cannot be applied to the vertical bucket warehouse type grain warehouse of the turnover warehouse. The top wall of the outer wall of the grain warehouse is provided with a phenolic resin foam material or a glass fiber mesh cloth insulation layer. The reflective heat insulation coating is located within the direction range of 90'E ~ 270'W, and is composed of solar heat reflective coating or radiation cooling coating to ensure that the temperature inside the wall is above 0°C in extremely cold winter conditions.
本发明一方面，利用日间强光照，太阳能产生电能，带动粮库内壁与地下水相连的地冷循环，降低粮库内部温度；另一方面，通过粮库表面反光材料的实施，降低粮库内外壁温差，以减少粮食结露、霉变损耗；具体过程如下： On the one hand, the present invention utilizes strong sunlight during the day to generate electric energy from solar energy, drives the ground cooling cycle in which the inner wall of the grain depot is connected with groundwater, and reduces the internal temperature of the grain depot; The temperature difference of the outer wall is used to reduce the loss of food condensation and mildew; the specific process is as follows:

本发明为自驱动设计，无额外电力和人力辅助，太阳直射时，太阳能电板工作带动内部水流电泵，形成地冷水流循环，降低墙体和仓内温度。本发明可应用区域为中纬度区域N40°00′ ~ N30°00′以及中低纬度区 N30°00′ ~ N23°27′。 The invention is a self-driven design without additional power and manpower assistance. When the sun is directly shining, the solar panels work to drive the internal water flow electric pump to form a ground-cooled water flow cycle and reduce the temperature in the wall and the warehouse. The applicable area of the present invention is the mid-latitude area N40°00′~N30°00′ and the mid-low latitude area N30°00′~N23°27′.
在粮库设计与建筑时，嵌入本系统；粮库运转时，一方面，利用日间强光照，太阳能产生电能，带动粮库内壁分布的地冷循环，降低粮库内部温度；另一方面，通过粮库表面反光材料的实施，降低粮库内外壁温差；自驱动地冷循环与表面隔热两者协同作用于粮库，大幅减少储存粮食结露、结顶、霉变等损耗。本发明为自驱动系统，无需额外电能，在日间光照强烈时，内部地冷循环自动运转；在夜间或阴雨天气时不工作。 This system is embedded in the design and construction of the grain depot; when the grain depot is in operation, on the one hand, using strong sunlight during the day, solar energy generates electricity, drives the ground cooling cycle distributed on the inner wall of the grain depot, and reduces the internal temperature of the grain depot; on the other hand, Through the implementation of reflective materials on the surface of the grain depot, the temperature difference between the inner and outer walls of the grain depot can be reduced; the self-driven ground cooling cycle and surface insulation work together on the grain depot to greatly reduce the loss of dew condensation, roof formation, and mildew of the stored grain. The invention is a self-driven system without additional electric energy. When the sunlight is strong during the day, the internal cooling cycle automatically operates; it does not work at night or in rainy weather.
本发明通过地冷循环和表面隔热联合降温处理，降低日间光照强烈时粮库温度，具有以下两大优点：一是节约能耗，传统降温方式为空调降温，能耗极大，本发明采用地下冷水资源来降低粮仓温度，且驱动力为太阳能转换，无额外能耗，大大节约能耗和成本。二是节省人力，本发明采用无人值守的自驱动设计，在日间阳光强烈时，系统自动介入，内部循环开启并降温。与传统降温方式相比，大大节省了人力资源。 The present invention reduces the temperature of the grain depot when the sunlight is strong in the daytime through the combined cooling treatment of the ground cooling cycle and surface heat insulation, and has the following two advantages: one is to save energy consumption. The traditional cooling method is air conditioning cooling, which consumes a lot of energy. Underground cold water resources are used to reduce the temperature of the granary, and the driving force is solar energy conversion, without additional energy consumption, which greatly saves energy consumption and cost. The second is to save manpower. The present invention adopts an unattended self-driven design. When the sunlight is strong during the day, the system will automatically intervene, and the internal circulation will be turned on and the temperature will be lowered. Compared with traditional cooling methods, it greatly saves human resources.
