Description

Technical Field

[0001] The utility model belongs to the technical field of circulating waste heat boilers, and in particular relates to a circulating waste heat boiler. Background Art

[0002] A circulating waste heat boiler is an energy recovery system, which usually includes components such as a waste heat recovery device, a circulating pump, a heat exchanger, and a control system. They are usually installed as a complete device at industrial sites or other appropriate places to recover waste heat generated in industrial processes and convert it into useful energy, such as steam or hot water;

[0003] Circulating waste heat boilers are usually used to recover waste heat generated in industrial processes, and waste heat generally comes from waste gas produced in industrial processes. Since the waste gas contains a large amount of impurities, circulating waste heat boilers usually use filter plates to filter waste smoke. However, since most waste gases usually contain moisture, when filtering with filter plates, these moisture are usually blocked, so that the water and dust on the filter plates are mixed, which in turn affects the efficiency of the device entering the waste gas and the recovery efficiency of heat energy. At the same time, the moisture adheres to the filter plate, which will also corrode the filter plate, thereby affecting the service life of the filter plate;

[0004] In order to solve the above problems, a circulating waste heat boiler is proposed in the present application. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a circulating waste heat boiler to overcome the above technical problems existing in the existing related technology.

[0011] Preferably, a heat-insulating box is fixedly connected to the inner bottom of the waste heat boiler body, and the drain pipe is located outside the heat-insulating box.

[0012] By setting up a thermal insulation box, the water tank can be insulated to prevent the explosion of the water tank from affecting the use of the waste heat boiler.

[0013] Preferably, a water baffle is fixedly connected to the inner side wall of the waste heat boiler body, and a side wall of the water baffle is fixedly connected to one side of the water collecting plate.

By using the cleaning structure 6, the first filter plate 7 and the second filter plate 8 in coordination, the moisture and dust in the exhaust gas can be filtered, so as to avoid the moisture and dust in the exhaust gas affecting the use of the waste heat boiler.

[0033] Reference Figure 1 and Figure 2The water collecting plate 9 is provided with a water collecting trough 10, which is used to collect sewage. The water collecting plate 9 is fixedly connected with a water pipe 11 through the water collecting trough 10, and the water pipe 11 is used to transport sewage. The inner bottom of the waste heat boiler body 1 is fixedly connected with a water storage tank 12, which is used to store sewage. The sewage pushed on the water collecting plate 9 is collected into the inside of the water storage tank 12 by using the water collecting trough 10 and the water pipe 11. The sewage is collected through the water storage tank 12. The top of the water storage tank 12 is fixedly connected with the bottom of the water pipe 11. The side wall of the water storage tank 12 is fixedly connected with a drain pipe 13, which is used to release sewage. The drain pipe 13 runs through the side wall of the waste heat boiler body 1.

[0038] Working principle:

[0039] The staff connects the exhaust pipe to the intake pipe 4. After the connection, the exhaust gas quickly enters the interior of the waste heat boiler body 1 through the intake pipe 4, first passes through the first filter plate 7 to filter the moisture in the exhaust gas, and then passes through the second filter plate 8 to filter the dust in the exhaust gas, and then begins to exchange heat inside the waste heat boiler body 1. At the same time, the exhaust gas entering through the intake pipe 4 causes the fan blade 602 to rotate. The rotation of the fan blade 602 will drive the connecting rod 603 and the striking rod 604 to rotate. The rotation of the striking rod 604 will strike the first filter plate 7, so that the first filter plate 7 starts to vibrate. The vibration of the first filter plate 7 will cause the moisture on the first filter plate 7 to fall off, and fall onto the top of the water collecting plate 9, and then fall into the water storage tank 12 through the water collecting trough 10 and the water pipe 11, so as to realize the collection of moisture. When the waste heat boiler stops, the sewage in the water storage tank 12 can be released through the drain pipe 13, so as to avoid excessive sewage in the water storage tank 12, which affects the collection effect of sewage.
