Description

Technical Field

[0001] This utility model relates to the field of boiler technology, specifically to a dual-cycle energy-saving and emission-reduction device for a thermal storage boiler. Background Technology

[0002] The dual-cycle energy-saving and emission-reduction device for thermal storage boilers is an energy-saving and emission-reduction equipment used in thermal storage boiler systems. A thermal storage boiler is a boiler that uses a thermal accumulator to store heat and releases it during peak demand periods to improve energy efficiency. The dual-cycle system refers to the installation of two circulation systems within the equipment to achieve more efficient utilization and recovery of thermal energy.

[0004] However, existing energy-saving and emission-reduction devices for thermal storage boilers also have certain shortcomings. Although existing energy-saving and emission-reduction devices for thermal storage boilers use structural components such as heat accumulators to convert the heat energy of hot flue gas for subsequent hot water input to achieve energy saving, the use of flue gas circulation pipes and hot water storage tanks alone will result in slow water heating efficiency due to the influence of water heat conduction efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A dual-cycle energy-saving and emission-reduction device for a thermal storage boiler includes a boiler body 1, a support frame 2 fixedly connected to the lower side of the boiler body 1, a hot water storage tank 3 installed on the upper side of the boiler body 1 via a support plate, a flue gas circulation pipe 4 provided on the upper side of the boiler body 1, the flue gas circulation pipe 4 being fixedly connected to the hot water storage tank 3, a coil 5 fixedly connected to the upper end of the flue gas circulation pipe 4, the coil 5 being located inside the hot water storage tank 3, and a filter water tank 6 fixedly connected to the upper end of the hot water storage tank 3.

[0025] A hot water circulation pipe 8 is fixedly connected to the inner wall of the hot water storage tank 3. The hot water circulation pipe 8 is fixedly connected to the boiler body 1. A pump body 9 is installed on the outer side of the horizontal part of the hot water circulation pipe 8. An installation cylinder 10 is fixedly connected to the vertical part of the hot water circulation pipe 8. A fixing rod 11 is fixedly connected to the inner wall of the installation cylinder 10. A guide plate 12 is slidably connected to the inner wall of the fixing rod 11. An impact plate 13 is fixedly connected to the left end of the guide plate 12. The impact plate 13 is slidably connected to the installation cylinder 10.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 An output pipe 7 is fixedly connected to the inner wall of the filter water tank 6. The output pipe 7 is fixedly connected to the hot water storage tank 3 and the coil 5. The output pipe 7 allows the flue gas to be output. A spring 14 is fixedly connected to the impact plate 13. The other end of the spring 14 is welded to the mounting cylinder 10. The spring 14 allows the impact plate 13 to be connected.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The hot water storage tank 3 is equipped with an agitation mechanism 15, which includes a telescopic rod 151. The telescopic rod 151 is slidably connected to the inner wall of the hot water storage tank 3. An agitation plate 152 is fixedly connected to the left end of the telescopic rod 151. The agitation plate 152 is located inside the hot water storage tank 3. A spring 153 is provided on the outer side of the telescopic rod 151. A ball 154 is fixedly connected to the right end of the telescopic rod 151. An installation plate 155 is fixedly connected to the right end of the hot water storage tank 3. A servo motor 156 is fixedly installed at the lower end of the installation plate 155. Through the coordinated use of the servo motor 156, the ball 154, and other structures, the telescopic rod 151 can drive the agitation plate 152 to move back and forth, agitating the water inside the hot water storage tank 3 to improve the heating efficiency of the water.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5The agitator plate 152 is rectangular in shape and made of high-temperature resistant plastic. The agitator plate 152 can push the water. The high-temperature resistant plastic material gives the agitator plate 152 good heat resistance and lightweight properties. One end of the spring 153 is welded to the hot water storage tank 3, and the other end of the spring 153 is welded to the end plate of the telescopic rod 151. The spring 153 can be used to connect the telescopic rod 151. A cam 157 is fixedly sleeved on the outside of the output shaft of the servo motor 156. The cam 157 contacts the ball 154. Through the cooperation of the cam 157 and the ball 154, the telescopic rod 151 can be pushed to move.

[0029] The specific implementation process of this utility model is as follows: In use, the hot flue gas generated by the combustion of the boiler body 1 can be transported through the flue gas circulation pipe 4, so that the hot flue gas flows into the coil 5, and the hot flue gas exchanges heat with the water in the hot water storage tank 3 to heat the water. Under the action of the output pipe 7 and the filter water tank 6, the outflowing flue gas can be filtered and reduced. Under the action of the pump body 9 and the hot water circulation pipe 8, hot water can be input into the boiler body 1 to achieve good dual-circulation energy saving and emission reduction operation.

[0030] When hot flue gas flows into the hot water storage tank 3, the servo motor 156 is started to drive the output shaft to rotate, which in turn drives the cam 157 to rotate. This causes the long side of the cam 157 to press against the ball 154. The ball 154 is forced to move to the left, which in turn drives the telescopic rod 151 to move to the left. The second spring 153 deforms and drives the agitator plate 152 to move. When the long side of the cam 157 disengages from the ball 154, the second spring 153 returns to its original shape, which pushes the telescopic rod 151 to move to the right, which in turn drives the agitator plate 152 to move to the right. This process is repeated, so that the agitator plate 152 agitates the water to improve the heating efficiency of the water.

[0031] When the hot water circulation pipe 8 delivers hot water instantaneously, the fluid impact force causes the fluid to come into contact with the impact plate 13, pushing the impact plate 13 to move to the left. As the impact plate 13 moves, it can drive the guide plate 12 to slide along the inner wall of the fixed rod 11 to ensure the stable movement of the impact plate 13. The spring 14 deforms to release the hard impact generated by the instantaneous flow of fluid, thus avoiding damage to the hot water circulation pipe 8 from the hard impact.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
