Description

Technical Field

[0001] The present invention belongs to the technical field of cold storage, smart agricultural planting and factory breeding of aquatic products, and specifically relates to an environmentally friendly, low-energy consumption enclosure structure with a raw soil-porous plant fiber composite structure. Background Art

[0002] Due to the rapid growth in demand for food and drug preservation, the annual growth rate of the refrigeration industry has remained at a high level of 15-20%, and in 2019, carbon emissions and energy consumption of cold storage in my country accounted for 2% and 20% of the global total, respectively. At the same time, high energy consumption is an important factor hindering the development of smart agricultural planting and factory farming of aquatic products. The mainstream maintenance structure in the above three fields is mainly civil engineering structure and polyurethane warehouse panels. In order to improve the insulation effect of these three fields, there are existing methods of superimposing multiple layers of different insulation materials, or increasing the thickness of polyurethane warehouse panels, and even relying on polyurethane foam to reduce the cold load. These measures have promoted the rapid growth of polyurethane enclosure structures in the Chinese market. For example, in 2019, the production and consumption of polyurethane (for cold storage) in China reached approximately 13.66 million tons and 2.07 million tons, respectively, and the annual growth rate of polyurethane foam plastics was as high as 7%.

[0003] However, this growth ignores the economic cost of polyurethane enclosures and their impact on the environment throughout their life cycle. In particular, during the production of polyurethane rigid foam, about 15% of waste is discharged directly without treatment, which may have a profound toxic impact on the environment, especially on the marine ecology. Therefore, it is particularly important to recycle discarded rigid polyurethane foam. However, the direct recycling method is not ideal at present, and the chemical recycling method is more effective but more expensive, which leads to unsatisfactory overall recycling performance of polyurethane.

[0004] Based on this, an environmentally friendly and low-energy envelope structure with a raw soil-porous plant fiber composite structure was proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an environmentally friendly, low-energy consumption enclosure structure of a raw soil-porous plant fiber composite structure in view of the deficiencies of the above-mentioned prior art, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an environmentally friendly low-energy consumption enclosure structure of a raw soil-porous plant fiber composite structure, including an enclosure structure wall and a passive vacuum system;

[0007] The wall of the enclosure structure is composed of a reinforced soil layer, an inner air layer, a middle air layer, an outer air layer and a water storage layer from the inside to the outside;

[0008] The top of the enclosure structure wall is connected to a connecting pipe above the inner air layer, the middle air layer, and the outer air layer respectively. The other ends of the multiple connecting pipes are connected to the bottom of the main power pipe, and a non-powered wind hood is installed on the top of the main power pipe to enhance the vacuum effect.

[0009] As a further explanation of the present invention, the reinforced soil layer includes a brick wall layer and a raw soil-porous plant fiber mixed layer. The porous plant fiber layer is mixed in the raw soil layer to form an intermediate layer, and cement layers are arranged on both sides of the intermediate layer.

[0010] As a further explanation of the present invention, the inner air layer, the middle air layer, and the outer air layer are separated by four partitions that are equally spaced between the raw soil, the reinforced soil layer, and the water storage layer. The partitions are composed of wooden strip partitions and plastic film layers. Plastic film layers are sealed and fixed on both sides of the wooden strip partitions, and a hollow air layer is formed between two adjacent partitions.

[0011] As a further explanation of the present invention, the wooden strip partition frame is specifically a tic-tac-toe shaped vertical frame made of wooden strips.

[0012] As a further explanation of the present invention, the aquifer is composed of a brick wall layer, a waterproof layer and a water layer. The waterproof layer is arranged on the surface of the brick wall layer to form a waterproof trough shape. The water layer is filled between the two brick wall layers to form an aquifer.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The enclosure structure wall of the present invention is composed of a five-layer structure cavity consisting of a soil layer reinforced with raw soil-porous plant fiber composite material, an inner air layer, an intermediate air layer, an outer air layer and an aquifer from the inside to the outside. Through scientific structural design and the use of renewable materials, good thermal insulation performance is achieved. At the same time, its high stability and safety are also guaranteed. The enclosure structure is suitable for promotion and use in various regions across the country and makes positive contributions to global sustainable development. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, the present invention provides a technical solution: an implementation scheme of an environmentally friendly low-energy consumption enclosure structure of a raw soil-porous plant fiber composite structure applied in the field of cold storage, comprising an enclosure structure wall 6, a connecting pipe 7 and a main power pipe 8;

[0022] The enclosure structure wall 6 is composed of a raw soil reinforcement layer 1, an inner air layer 2, a middle air layer 3, an outer air layer 4 and an aquifer 5 from the inside to the outside.

[0023] The raw soil reinforcement soil layer 1 comprises a brick wall layer 11 and a raw soil-porous plant fiber composite material layer 12. The raw soil-porous plant fiber composite material layer 12 is specifically raw soil mixed with a certain proportion of porous plant fibers, and the plant fibers are specifically rice straw, wheat straw or sugarcane peel, wherein the mass ratio of water to raw soil is 0.5:1, the long plant fibers in the plant fibers are 4-10 cm in length, and their mass accounts for 1%-4% of the total mass of the raw soil, and the short plant fibers in the plant fibers are 0.5-4 cm in length, and their mass accounts for 4%-20% of the total mass of the raw soil.

[0024] The raw soil reinforcement layer 1 is solidified again by adding to form a solid soil wall.

[0025] The inner air layer 2, the middle air layer 3, and the outer air layer 4 are separated by four partitions that are evenly spaced between the raw soil reinforcement layer 1 and the water storage layer 5. The partitions are composed of a wooden strip partition frame 21 and a plastic film layer 22. The wooden strip partition frame 21 is specifically a criss-cross shaped vertical frame made of wooden strips. Plastic film layers 22 are sealed and fixed on both sides of the wooden strip partition frame 21, and a hollow air layer is formed between two adjacent partition layers.

[0026] The aquifer 5 is composed of a waterproof brick wall layer 51 and a water layer 52 . Two waterproof brick wall layers 51 are provided, and the water layer 52 is filled between the two brick wall layers 51 to form the aquifer 5 .

[0027] The top of the enclosure structure wall 6 is connected to a connecting pipe 7 above the inner air layer 2, the middle air layer 3, and the outer air layer 4 respectively, and the other ends of the multiple connecting pipes 7 are connected to the main power pipe 8.

[0028] The sizes of the connecting pipe 7 and the main power pipe 8 should be determined according to the volume of the cold storage. The following table gives three typical ratio schemes;

[0029]

[0030] The advantage of this approach is that when the air in the inner air layer 2, the middle air layer 3, and the outer air layer 4 continues to heat up, once it is higher than the ambient temperature, the air inside the air wall will have a tendency to flow through the pipe due to the pressure difference caused by the density difference, and then be discharged into the environment through the pipe, which can create a negative pressure state in the air wall, which will greatly reduce the thermal conductivity of the air wall, and thus reduce the impact of the external ambient temperature on the internal temperature of the cold storage. Furthermore, in summer, the negative pressure effect is significantly better than the negative pressure effect in winter, but actual operation shows that negative pressure can also be formed in winter.

[0031] The thickness of the inner air layer 2, the middle air layer 3, and the outer air layer 4 can be set according to the actual cold storage volume. Typical cases are shown in the table below.

[0032] serial number Cold storage capacity Pipe diameter 1 <30 cubic meters 0.1-50mm 2 30-100 cubic meters 0-100mm 3 100-500 cubic meters 0-200mm 4 500-1000 cubic meters 0-350mm

[0033] Furthermore, a water storage layer 5 is arranged outside the three-layer air wall of the inner air layer 2, the middle air layer 3, and the outer air layer 4. The advantage of water having a large specific heat is used to block the influence of solar radiation on the internal temperature of the cold storage. The specific water storage capacity can be set according to the solar radiation conditions of the actual project location. For example, if the water storage capacity is 10 tons and the water temperature rises by 1 degree, it can resist the heat of the sun irradiating the outer wall of 19.5 square meters of the cold storage for 1 hour. If there is no water storage layer, the sun irradiates the surface of the cold storage for 1 hour, and the temperature rises to 10-20 degrees. This method is cheap, simple, and suitable for engineering applications. The water storage capacity can be determined according to the volume of the cold storage or the surface area of ​​the cold storage.

[0034] serial number Cold storage capacity Pipe diameter 1 <30 cubic meters 0-5 tons 2 30-100 cubic meters 0-20 tons 3 100-500 cubic meters 0-30 tons 4 500-1000 cubic meters 0-50 tons
