Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fuel drying, in particular to a fuel drying structure for airing. Background Art
[0002] With the green and low-carbon transformation of energy in China, recyclable fuels with zero-carbon attributes such as biomass and sludge have gradually come into the public view. However, such fuels generally have the characteristics of high moisture content, low calorific value, and difficulty in combustion. To improve the burnability of boilers for such fuels, certain means are needed to reduce the moisture content of the fuels.
[0003] Traditional biomass drying methods mainly rely on natural open-air airing. This method has a large amount of dust and is easily affected by the climate. Moreover, it is greatly affected by the climate. For example, during the rainy season, the fuel is easily wetted by rain, resulting in problems such as being unable to be aired. Therefore, it still needs to be improved. Summary of the Utility Model
[0004] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a fuel drying structure for airing.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A fuel drying structure for airing, comprising a support and a shed film capable of transmitting light. The shed film is installed on the support and is propped open by the support to enclose a shed space between the inside of the shed film and the ground. At least part of the bottom of the shed film is spaced from the ground vertically to form a lower opening, and the top of the shed film is open to form an upper opening; a rain shield for shielding the upper opening is further provided on the support.
[0007] Compared with the prior art, the advantages of adopting this solution are as follows:
[0008] In this solution, the shed film is propped up by the support, so that a shed space is enclosed between the shed film and the ground. The shed space is used as a drying space for the fuel; during drying, the fuel to be dried is spread on the ground in the shed space. Since the shed film is light-transmitting, it can ensure that the fuel in the shed can be irradiated by sunlight for drying.
[0009] In addition, in this solution, the setting of the upper opening and the lower opening enables an air flow channel to be formed between the bottom wall and the top of the shed film. Hot air flows out from the upper opening, and cold air is supplemented from the lower opening, so that natural ventilation and circulation can be carried out in the shed space, and water vapor can be discharged from the shed space in time along with the hot air.
[0010] Compared with the traditional open-air drying method, in this solution, by setting the shed film, rainwater can be blocked, daily drying during the rainy season can be realized, and at the same time, the dust or odor overflow during drying can be greatly reduced.
[0011] In addition, the provision of the rain shield can prevent rainwater from falling into the shed through the upper opening.
[0012] As an alternative embodiment, the bracket includes a column and a number of guy ropes arranged in sequence along the circumferential direction of the column. One end of each guy rope is fixed to the column, and the other end is fixed to the ground; the shed film is fixed to each guy rope in sequence along the circumferential direction of the column and is supported and unfolded by the guy ropes.
[0013] As an alternative embodiment, the bottom of the shed film is spaced from the ground to enable the lower opening to surround the space inside the shed; and / or the upper end of the shed film is spaced from the circumferential wall of the column to form an upper opening surrounding the column in a circle.
[0014] As an alternative embodiment, the rain shield is located above the shed film and fixed to the column.
[0015] As an alternative embodiment, a drain ditch surrounding the space inside the shed is provided on the ground at the position of the lower opening.
[0016] As an alternative embodiment, at least part of the lower opening has a height in the vertical direction that allows vehicles to pass through.
[0017] As an alternative embodiment, an anti-seepage film is laid on the bottom surface of the space inside the shed.
[0018] As an alternative embodiment, the shed film has a cone structure that is narrower at the top and wider at the bottom.
[0019] As an alternative embodiment, a fire extinguishing system is provided in the space inside the shed.
[0020] As an alternative embodiment, the shed film is made of ETFE material.
[0021] Other advantages and effects of the present utility model are specifically explained in the specific implementation manner and the accompanying drawings section. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.
[0025] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.
[0026] Example 1
[0027] See also Figure 1 and Figure 2 As shown, this embodiment provides a fuel drying structure, including a bracket and a greenhouse film 2. This embodiment can be used for drying biomass fuel, sludge and other fuels.
[0028] In order to ensure that daylight (sunlight) can pass through the greenhouse film 2 normally, the greenhouse film 2 is made of a light-transmitting film. In some embodiments, the greenhouse film 2 can be made of ETFE material. The light transmittance of the greenhouse film 2 of this material can reach more than 90%, and it does not block the transmission of ultraviolet rays and other light, which can ensure sufficient daytime radiation and is conducive to the drying of fuel.
[0029] Moreover, the ETFE film has good properties such as high strength, light weight, heat insulation, corrosion resistance, radiation resistance, and self-cleaning, so it can be well applied in this embodiment.
[0030] like Figure 1 As shown, the bracket is mainly used to support the greenhouse film 2 so that the greenhouse film 2 can be unfolded. Specifically, the greenhouse film 2 is installed on the bracket and is stretched by the bracket to form a greenhouse space between the inside of the greenhouse film 2 and the ground. When drying, the fuel to be dried is laid on the bottom surface of the greenhouse space. Since the greenhouse film 2 is light-transmitting, it can ensure that the fuel in the greenhouse can be exposed to sunlight for drying.
[0031] Compared with the traditional open-air drying method, the present embodiment can block rainwater by providing the shed film 2, thereby achieving daily drying in the rainy season and greatly reducing dust or odor overflow during drying.
[0032] In addition, in order to ensure normal ventilation inside and outside the space inside the shed, in the present embodiment, the bottom of the shed film 2 is at least partially vertically spaced from the ground to form a lower opening 21, and the top opening of the shed film 2 is arranged to form an upper opening 22; an air flow channel is formed between the bottom wall and the top of the shed film 2, and the hot air in the shed flows out from the upper opening 22, and the cold air is replenished into the shed from the lower opening 21, thereby enabling the space inside the shed to undergo a natural ventilation cycle, so that water vapor is discharged from the space inside the shed in a timely manner along with the hot air.
[0033] Due to the existence of the upper opening 22, rainwater may enter the shed space through the upper opening 22 and wet the fuel inside the shed. Therefore, in this embodiment, as Figure 1 shown, a rain shield 13 for shielding the upper opening 22 is further provided on the support. It should be noted that the shielding here refers to shielding without closing the upper opening 22, that is, it is necessary to ensure that the upper opening 22 has normal air flow conductivity. For example, in this embodiment, the rain shield 13 is arranged at a certain distance above the upper opening 22. In the vertical projection, the projection of the upper opening 22 is within the projection range of the rain shield 13.
[0034] In some embodiments, as Figure 1 shown, the support includes a column 11 and a plurality of guy ropes 12 arranged in sequence along the circumference of the column 11. The guy ropes 12 are inclined. One end of the guy rope 12 is fixed on the column 11, and the other end is fixed to the ground. For example, the guy rope 12 is fixed by pouring a foundation or driving a pile on the ground.
[0035] The shed film 2 is sequentially fixed on each guy rope 12 around the circumference of the column 11 and is supported and unfolded by the guy ropes 12. At this time, all the guy ropes 12 are equivalent to the skeleton for supporting and fixing the shed film 2, and the entire shed film 2 is supported by the guy ropes 12.
[0036] As Figure 2 shown, through the inclined guy ropes 12, the shed film 2 has a conical structure with a narrower upper part and a wider lower part. It can also be understood that the space inside the shed has a conical shape with a narrower upper part and a wider lower part, so that the foundation area of the space inside the shed is larger to be able to lay more fuel for drying.
[0037] The specific formation of the upper opening 22 and the lower opening 21 can be:
[0038] The bottom of the shed film 2 is spaced from the ground, that is, the bottom of the shed film 2 does not contact the ground, thus forming a lower opening 21 surrounding the space inside the shed.
[0039] The upper end (or the top) of the shed film 2 is spaced from the peripheral wall of the column 11, that is, the top of the shed film 2 does not contact the peripheral wall of the column 11, so as to form an upper opening 22 surrounding the column 11 in a circle.
[0040] The rain shield 13 is fixed on the column 11 above the shed film 2 to shield the upper opening 22. Among them, the outer side surface of the rain shield 13 has a conical surface structure surrounding the column 11, so that the rainwater can slide down along the conical surface after falling on the rain shield 13.
[0041] In addition, in order to prevent the rainwater on the ground from flowing into the shed space through the lower opening 21 along the ground, in this embodiment, as Figure 1As shown, a drain ditch 3 surrounding the space inside the shed is provided on the ground at the position of the lower opening 21. For example, the lower edge of the shed film 2 is directly above the drain ditch 3. By providing the drain ditch 3, rainwater on the ground outside the shed can be intercepted from flowing into the shed.
[0042] At least part of the lower opening 21 has a height in the vertical direction that allows vehicles such as loading trucks or stackers to pass through. For example, a certain area or the whole of the lower opening 21 is designed to be increased in height, so that this part of the area serves as the entrance and exit for vehicle passage, thus facilitating vehicles carrying fuel to directly enter and exit the shed.
[0043] For the drying of some sludge-type fuels, in order to prevent the sewage in the sludge from seeping into the ground and causing pollution, in this embodiment, when drying sludge-type fuels, one or more anti-seepage membranes 4 can be laid on the bottom surface of the space inside the shed to prevent sewage from seeping into the ground.
[0044] Embodiment 2
[0045] Considering that it is for the drying of fuels, since fuels are flammable and there may be a situation where the fuel catches fire during the drying process, thus this embodiment is further improved on the basis of Embodiment 1. Specifically:
[0046] A fire extinguishing system is provided in the space inside the shed.
[0047] In some embodiments, the fire extinguishing system includes a smoke sensor 51 and a spraying mechanism. The spraying mechanism mainly includes a number of nozzles 52 provided inside the shed, and at least part of the spraying direction of the nozzles 52 is towards the ground where the fuel is laid; the nozzles 52 are connected to a water source such as municipal tap water or a fire hydrant through pipelines. When the smoke sensor 51 detects smoke inside the shed, the fire hydrant or the tap water is automatically opened, so that the nozzles 52 spray water inside the shed to extinguish the fire and prevent the fire from spreading. This kind of fire protection system has been widely used in existing buildings, and will not be elaborated here too much.
[0048] Among them, the nozzles 52 and the smoke sensor 51 can be fixed on the columns 11, or can be fixed on the guy ropes 12. There is no specific limitation here, and it can be selected according to actual needs.
[0049] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
