Technical Field

[0001] The utility model relates to the technical field of waste gas cooling, in particular to a waste gas cooling device for a heat storage combustion device. Background Art

[0002] Waste gases from industrial production often have harmful effects on the environment and human health. Purification measures must be taken before they are released into the atmosphere to ensure they meet emission standards. This process is called waste gas purification. Common waste gas purification methods include absorption, adsorption, condensation, and combustion.

[0003] Boilers are often used for heating in industrial production processes. After combustion in the boiler, waste gas is generated. After treatment, the waste gas is directly introduced into the smoke exhaust chimney, so that the waste gas rises in the chimney and cools naturally. This exhaust method easily causes heat waste in the waste gas, and at the same time interferes with the surrounding climate, changes the surrounding climate, and causes damage to the surrounding environment.

[0019] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figures 1 to 4 The exhaust gas cooling device shown is for a thermal storage combustion device, comprising an exhaust channel 1. A connecting pipe 2 is connected to the bottom of the outer side of the exhaust channel 1. A cooling pipe 3 is wound around the outside of the exhaust channel 1. The cooling pipe 3 is composed of two sets of interlaced guide pipes 4 connected to each other. The cooling pipe 3 is embedded in the outside of the exhaust channel 1. Support columns 5 are fixed on all four sides of the top of the exhaust channel 1. A cap 6 is fixed on the top of the support column 5. The cap 6 is covered on the outside of the exhaust channel 1. The inner cavity of the exhaust channel 1 is provided with multiple groups of buffer components 7 for decelerating the exhaust gas.

[0021] By movably setting a movable baffle 72 in the smoke exhaust channel 1, when the exhaust gas rises from the smoke exhaust channel 1, the movable baffle 72 can slow down the exhaust gas, which not only slows down the flow speed of the exhaust gas, but also allows the exhaust gas to stay in the smoke exhaust channel 1 for a longer time, making it convenient for the heat conduction block 11 to conduct the heat in the exhaust gas outward, exchange heat with the cooling pipe 3, and utilize the heat in the exhaust gas. At the same time, it can quickly reduce the temperature of the exhaust gas, and reduce the heat discharged into the air to a minimum to avoid affecting the surrounding environment. At the same time, the cooling pipe 3 recovers the heat in the exhaust gas and reuses it, thereby improving energy utilization.

[0022] The buffer assembly 7 includes a movable shaft 71 that rotates in the inner cavity of the smoke exhaust channel 1 through a bearing. A movable baffle 72 is fixed to the surface of the movable shaft 71. One side of the movable baffle 72 is in contact with the inner wall of the smoke exhaust channel 1, and the other side of the movable baffle 72 extends outward. A support spring 73 is fixed to the bottom of the movable baffle 72, and the other side of the support spring 73 is fixed to the inner wall of the smoke exhaust channel 1. The movable baffle 72 can be movably connected to the inside of the smoke exhaust channel 1 through the movable shaft 71, and then the support spring 73 supports the movable baffle 72, so that the movable baffle 72 is distributed in an inclined shape in the smoke exhaust channel 1, and then deflected by the exhaust gas, which has the effect of slowing down the rise of the exhaust gas.

[0023] A protective cover 8 is fixed to the outside of the smoke exhaust channel 1. The protective cover 8 is located on the outside of the cooling pipe 3. The liquid inlet and outlet of the cooling pipe 3 both pass through the protective cover 8 and extend outward. Through the setting of the protective cover 8, not only can the cooling pipe 3 be safely protected to prevent the cooling pipe 3 from being exposed to the outside and damaged, but also the heat can be isolated to prevent the heat in the cooling pipe 3 from diffusing outward, resulting in a low heat recovery rate.

[0024] Ladders 9 are fixed on the surface of the smoke exhaust channel 1 from top to bottom. The ladders 9 pass through the protective cover 8 and extend outward. The setting of the ladders 9 makes it convenient for maintenance personnel to climb and maintain the smoke exhaust channel 1 to avoid blockage inside the smoke exhaust channel 1 and inconvenience in clearing.

[0025] A mounting flange 10 is fixed to the end of the connecting pipe 2 away from the smoke exhaust channel 1, and a mounting hole is provided on the surface of the mounting flange 10. Through the arrangement of the mounting flange 10 and the mounting hole, the smoke exhaust channel 1 is conveniently connected to the smoke exhaust port of the boiler, so that the exhaust gas generated by the boiler can directly enter the smoke exhaust channel 1.

[0026] The cross section of the inner cavity of the smoke exhaust channel 1 is rectangular, and the movable shaft 71 is distributed on the inner wall of the smoke exhaust channel 1 in a staggered spiral shape. By setting the shape of the inner cavity of the smoke exhaust channel 1, the movable baffle 72 can be easily deflected up and down to buffer the flow of exhaust gas.

[0027] A heat-conducting block 11 is embedded in the interior of the smoke exhaust channel 1. The facing side of the heat-conducting block 11 penetrates the inner cavity of the smoke exhaust channel 1, and the other end of the heat-conducting block 11 is fitted with the cooling pipe 3. Through the setting of the heat-conducting block 11, the heat inside the smoke exhaust channel 1 is conveniently conducted outward, thereby reducing the time for heat exchange between the cooling pipe 3 and the smoke exhaust channel 1.

[0028] During specific use, the user connects the smoke exhaust channel 1 to the smoke exhaust port of the boiler through the connecting pipe 2, and the generated exhaust gas is introduced into the smoke exhaust channel 1. Then the exhaust gas rises in the smoke exhaust channel 1, and at the same time pushes the movable baffle 72 to move upward to slow down the rising speed. Then the heat in the exhaust gas diffuses outward along the smoke exhaust channel 1 and the heat conductive block 11, and then the heat is absorbed by the cooling pipe 3, heating the coolant inside the cooling pipe 3, and then the heat is discharged along with the coolant, and the heat is recycled.

[0029] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
