Description

Technical Field

[0001] The invention relates to the technical field of heat collection equipment, and in particular to energy-saving, environmentally friendly and explosion-proof heat collection engineering equipment. Background Art

[0002] In all heat collection projects, the commonly used heat collection and utilization equipment is solar energy equipment. Solar water heaters are heating devices that convert solar energy into thermal energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, mainly vacuum tube solar water heaters. Vacuum tube household solar water heaters are composed of heat collection tubes, water storage tanks, brackets and other related parts and components. The conversion of solar energy into thermal energy mainly depends on vacuum heat collection tubes. Vacuum heat collection tubes use the principle of hot water floating and cold water sinking to make water microcirculate and obtain the required hot water. The heat collection project is to combine multiple solar water heaters through a series of connections. Whether it is a single solar water heater or an overall heat collection project, it will be used on cloudy days during use. Even in the rainy season, electric heating will be used to assist the cold water in the solar water tank to heat. In the process of heating on cloudy days, it is inevitable that the sun will not be enough, and the water temperature in the large-capacity water tank will not reach the ideal temperature. In addition, during use, scale will be generated in the heat collection tube 1 and the water tank, especially in the heat collection tube 1. It is the main place for scale to be generated. Since the heat collection tube 1 is directly inserted into the inner tank 2-1 of the water tank and the water in the water tank is first heated by the heat collection tube 1 and then passed through the internal microcirculation to the water tank, the scale generated in the water tank is difficult to clean. Most of the existing heat collection tubes 1 have a tube length of 1.78m. However, in the case of insufficient heat collection on cloudy days, the heat collection tube 1 must be inserted into the inner tank 2-1 inside the water tank, which virtually reduces the area of ​​heat collection. Summary of the invention

[0003] The purpose of the present invention is to provide an energy-saving, environmentally friendly and explosion-proof heat collection engineering equipment to solve the problem that the existing solar water heaters are difficult to reach the required temperature and are prone to scale generation in the water tank during use in rainy seasons.

DETAILED DESCRIPTION OF THE INVENTION

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Embodiment 1:

[0030] An energy-saving, environmental protection and explosion-proof heat collection engineering device as shown in the figure, which includes a heat collection tube 1, a water tank, a bracket, and a descaling tank 6. In this device, for the convenience of placement, the water tank is fixedly arranged on the bracket, and the heat collection tube 1 is arranged on the bracket and connected to the water tank. A descaling tank 6 is arranged on the bracket and communicated with the water tank. The descaling tank 6 has at least two purposes here. One is to heat, and the other is to aggregate scale. In order to improve the use efficiency of the heat collection tube 1, a compensation device 3 is arranged at the connection between the heat collection tube 1 and the water tank. In equipment using solar heat collection, the places where scale is easily generated are inside the heat collection tube 1 and at the connection between the water tank and the heat collection tube 1. Generally speaking, it is where the water flow is mainly heated. As the water is heated, after the hard water is heated and boiled, the minerals contained adhere to the inner wall of the container and gradually form white lumps or powders. The main components include calcium carbonate, magnesium hydroxide, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, magnesium chloride, etc. Since the heat collection tube 1 is a glass tube, it is convenient to remove the scale even if it is generated. However, the inner liner 2-1 of the water tank is made of metal, and the generated scale is not easy to handle. The scale generated in the water tank can only exist until it is scrapped, which is a waste of the use of the water tank. In this application, a separate descaling tank 6 is set to remove scale from the water, and at the same time, the descaling tank 6 is also used to heat the water in other ways, so that the entire heat collection system and descaling are perfectly integrated, which not only increases the flexibility of heat collection but also facilitates preventing scale from generating in the water tank. At the same time, this device uses a compensation device 3 to compensate for the part of the heat collection area lost due to the connection between the heat collection tube 1 and the water tank, which virtually increases the heat collection efficiency. At the same time, the device can also prevent explosion to a certain extent, that is, prevent explosion inside the water tank.

[0031] Embodiment 2:

[0032] Based on the above embodiments, in this embodiment, another structure of the device to prevent the water in the water tank from not reaching the required temperature is to divide the water tank into two layers. In a 100-liter water tank, 12 heat collector tubes 1 are connected for heating. During the heating process, since 100 liters of cold water and hot water are mixed together, assuming that all 100 liters of water can be heated to 100 degrees in four hours under sufficient sunlight, then in these four hours, the 100 liters of water in the water tank shows an average temperature increase. However, the water in the water tank is stratified throughout the process. The principle of solar heating is that hot water rises and cold water descends. Therefore, the temperature of the upper layer of water is higher than that of the lower layer. But since all 100 liters of water are in one water tank, even if the hot water is stratified, during use, due to water mixing, the water discharged will not be too hot. The method of this device is to divide the water tank into sections. The water tank includes a first water tank 2 and a second water tank; the bracket includes a first bracket 4, a second bracket and a connecting plate 5. The heat collector tube 1 and the first water tank 2 are fixedly arranged on the first bracket 4. The second bracket is arranged on the back of the first bracket 4 and is firmly connected. One end of the connecting plate 5 is connected to the second bracket, and the other end is connected to the first bracket 4 below the heat collector tube 1; the second water tank is fixedly connected to the second bracket and is arranged directly above the first water tank 2 or at a 45-degree angle with the first water tank 2. The back of the connection between the second bracket and the second water tank is fastened with screws. The first water tank 2 and the second water tank are connected by a first connecting water pipe. In this way, the original 100-liter water tank is divided into two 50-liter water tanks. In this way, during the heating process, a total of three microcirculations are formed in the water in the lower water tank and the upper water tank, between the upper and lower water tanks, and the self-circulation in the water tank. This can keep the temperature of the water in the upper water tank higher than that in the lower water tank.

[0033] Furthermore, appropriate control is carried out through valves connected by water pipes. Specifically, water outlet pipes are arranged in the first water tank 2 and the second water tank respectively, and solenoid valves are arranged on the water outlet pipes. Then the two pipes are connected into one water outlet. A solenoid valve is arranged on the water pipe between the first water tank 2 and the second water tank. The water inlet pipe is arranged on the first water tank 2 and a solenoid valve is arranged on the water inlet pipe. Liquid level gauges are arranged in the first water tank 2 and the second water tank and are connected to the controller. Each solenoid valve is connected to the controller.

[0034] In this device, in order to discharge water in layers, liquid separation water outlets are arranged in the first water tank 2 and the second water tank. The liquid separation valve water outlets include multiple water outlet branch pipes. Each water outlet branch pipe extends out of the water tank and is connected to the water outlet pipe. The water outlet branch pipes are arranged with more than 3 pipes from top to bottom. It is preferably set to 4 pipes, which are respectively located in the upper middle, middle and bottom of the water tank. Except for the water outlet pipe at the top, a float valve is arranged at the water outlet of each of the upper, middle and lower parts. The float valve uses a round rod that can float on the water surface as a driving switch. Specifically, it includes a threaded water pipe A connected to the water tank. The thread of the threaded water pipe A is arranged at the other end of the water pipe. Inside the threaded water pipe A, such asFigure 8 The inner plug tube I of the shown structure is threadedly connected to the threaded joint B connected to the inner plug tube I. The other end on the outer side of the threaded joint B is also provided with an external thread for connection to other water pipes. A water retaining ring E and a spring retaining ring D are arranged at the inner tail of the inner plug tube I. A water retaining piece G is arranged inside the water retaining ring E. The structure and position of the water retaining piece G and the water retaining ring E are as Figure 7 shown. The periphery of the water retaining piece G is provided with a water-passing groove, but its inner ring can completely fit on the water retaining ring E to form a sealed connection structure. A floating round rod C is connected to the center of the water retaining piece G. A spring F is arranged between the water retaining piece G and the spring retaining ring D. Thus, in this design, the float valve is placed vertically, and a float is connected by a wire on the floating round rod C. In this way, when the water tank is full of water, due to the buoyancy of the water on the float and the floating round rod C, the valve is closed. When the water level drops to a certain extent, the float and the floating round rod C lose the buoyancy of the water, and the floating round rod C tilts under its own weight, thus opening the float valve and starting to discharge water. The setting method is as Figure 8 shown.

[0035] Embodiment 3:

[0036] Based on the above embodiment, in this embodiment, in order to keep the water temperature in the water tank from flowing away, the descaling tank 6 is set as a heat-insulating cylinder. The descaling tank 6 is fixedly arranged on the first bracket 4 and is located below the first water tank 2. The descaling tank 6 is connected to the first water tank 2 through a heat-insulating water pipe 7. A coil pipe is arranged in the descaling tank 6, and the coil pipe is connected to a ground pump or an electric heating device. In this way, it not only meets the requirement of removing water scale but also has other auxiliary heating functions and is convenient for replacement.

[0037] Embodiment 4:

[0038] Based on the above embodiment, in this embodiment, another setting method of the descaling tank 6 is to fixedly arrange the descaling tank 6 between the heat collecting pipe 1 and the first water tank 2. The descaling tank 6 is connected to the first water tank 2 through the heat collecting pipe 1 or the heat-insulating water pipe 7. In this way, the descaling tank 6 is directly connected to the heat collecting pipe 1, which can better remove the scale from the water heated by the heat collecting pipe 1. The water scale will eventually accumulate in the descaling tank 6 and will not enter the water tank, preventing the water tank from generating scale and protecting the water tank, thus increasing the service life of the water tank.

[0039] Embodiment 5:

[0040] Based on the above embodiment, in this embodiment, in order to increase the heat collecting area of the whole device, the descaling tank 6 is made of the same material as the heat collecting pipe 1. In this way, during the use process, there will be one more heat collecting device.

[0041] Embodiment 6:

[0042] Based on the above embodiments, in this embodiment, as is well known, solar collectors are relatively prone to explosion. Moreover, since the heat collecting pipe 1 is inserted into the inner tank 2-1 of the water tank, the section from the inner tank 2-1 to the outer box 2-2 is hidden inside the water tank and cannot receive sunlight, resulting in a certain loss of heat collecting area invisibly. Assuming the shortest length is 8 cm, a heat collecting project with 25 pipes will have a reduction of 8×25 = 200 cm in the length of the heat collecting pipe 1, which is close to the length of 1.5 heat collecting pipes 1. This is undoubtedly very wasteful. This device replaces this part of the heat collecting pipe 1 through the compensation device 3 to increase the heat collecting area. Specifically, the compensation device 3 includes a first fastening sleeve 8, a second fastening sleeve 9, a third fastening sleeve 10, and a high-temperature resistant water pipe; the first fastening sleeve 8 is sleeved at the place where the heat collecting pipe 1 was originally inserted into the outer box 2-2 of the first water tank 2; the second fastening sleeve 9 is sleeved at one end of the high-temperature resistant water pipe, and the second fastening sleeve 9 is sleeved inside the heat collecting pipe 1; the third fastening sleeve 10 is sleeved at the place where the heat collecting pipe 1 was originally inserted into the inner tank 2-1 of the first water tank 2, and the high-temperature resistant water pipe is inserted into the third fastening sleeve 10. Since a high-temperature resistant water pipe is used to compensate for the part inserted into the inner tank 2-1 and replace the original pipe, and at the same time, through reasonable setting of the fastening sleeves, while fastening the pipes, the purpose of reducing the connection strength is also achieved. In this way, when the water pressure in the water tank reaches a certain level, the heat collecting pipe 1 is disengaged from the water tank to prevent explosion. In this way, both the heat collecting area is increased and the explosion-proof function is achieved, which can kill two birds with one stone.

[0043] Embodiment 7:

[0044] Based on the above embodiments, in this embodiment, in order to prevent the fastening sleeves from falling off the heat collecting pipe 1, the water tank and the water tank, the first fastening sleeve 8 and the third fastening sleeve 10 are set to be H-shaped. The first fastening sleeve 8 is embedded on the outer box 2-2, and the third fastening sleeve 10 is embedded on the inner tank 2-1. The second fastening sleeve 9 is set to be stepped. The first step is inserted into the heat collecting pipe 1, and the second step is embedded in the filler 2-3. The filler 2-3 is filled between the inner tank 2-1 and the outer box 2-2.

[0045] Embodiment 8:

[0046] Based on the above embodiments, in this embodiment, in order to make reasonable use of the limited space and reasonably arrange the positions of the fastening sleeves, etc., a heat insulation layer 11 is provided between the inner tank 2-1 and the filler 2-3, and the thickness on one side of the third fastening sleeve 10 is the same as that of the heat insulation layer 11.
