Description

Technical Field

[0001] This application relates to the field of vacuum hot water boilers, and more specifically, to a low-NOx emission structure for vacuum hot water boilers. Background Technology

[0002] During boiler operation, the flue gas emitted from the upper chimney exhaust port is at a very high temperature, and a large amount of heat is released into the atmosphere. The waste heat utilization rate of the flue gas passage is not high, resulting in a large amount of energy waste and failing to achieve the effect of fully utilizing energy.

[0003] The structure of the product can be referenced from a low-NOx emission boiler disclosed in Chinese Patent Document 202220003836.7, which includes a boiler drum, a furnace shell, a combustion chamber, a first flue pipe, and a burner. One end of the furnace shell is connected to the boiler drum, and the other end extends into the boiler drum. A first flue chamber is provided outside the boiler drum and is connected to the boiler's exhaust port. The burner is located at the end of the furnace shell connected to the boiler, and the combustion chamber is located at the end of the furnace shell extending into the boiler drum. One end of the first flue pipe is connected to the combustion chamber, and the other end extends into and is connected to the first flue chamber. A heat exchange pipe is provided inside the first flue chamber. The inlet end of the heat exchange pipe extends out of the first flue chamber to connect to an air source, and the outlet end of the heat exchange pipe extends out of the first flue chamber to connect to the burner. An air electric heater is provided outside the first flue chamber, and the heat exchange pipe is connected to the burner through the air electric heater. It can utilize the waste heat of the flue gas passage to preheat the air, improve and control the air inlet temperature, improve energy utilization, and control NOx generation.

[0004] However, this patent does not have the effect of filtering impurities, causing impurities to be discharged outside and affecting the environment.

[0005] A low-NOx emission structure for a vacuum hot water boiler with impurity filtration is now provided. Utility Model Content

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a low-NOx emission structure for a vacuum hot water boiler, comprising: a boiler body; four support rods fixedly connected to the boiler body in a matrix arrangement; a water inlet at the top of the boiler body; a water outlet at the bottom of the boiler body; an air outlet on the boiler body; a mounting box fixedly connected to the air outlet; a first adsorption screen detachably mounted on the mounting box; a second adsorption screen detachably mounted on the mounting box; and a cleaning component on the mounting box for cleaning the first and second adsorption screens.

[0008] The exhaust gas is discharged through the outlet. Then, under the action of the first adsorption net, nitrogen is adsorbed, achieving low-NOx emissions. Under the action of the second adsorption net, impurities are adsorbed, preventing environmental pollution. A servo motor can be activated, causing its output shaft to drive a rotating rod, which in turn drives a worm gear, which in turn drives a turbine, causing a lead screw to rotate back and forth. This causes the connecting block to move up and down, which in turn causes the rotating shaft to move up and down, thus causing the cleaning brushes to move up and down. The two cleaning brushes clean the first and second adsorption nets through their movement. Simultaneously, under the action of the rack and pinion mechanism, the rotating shaft rotates back and forth as it moves up and down, causing the cleaning brushes to rotate back and forth, further improving the cleaning effect. The fixing bolts can be rotated to remove the first and second adsorption nets for easy replacement or cleaning.

[0009] Furthermore, the first adsorption net and the second adsorption net are slidably mounted on the mounting box, and connecting pieces are fixedly connected to the first adsorption net and the second adsorption net, and fixing bolts are threadedly connected to the connecting pieces, and the fixing bolts are threadedly connected to the mounting box.

[0010] Furthermore, both the connecting block and the fixing bolt are provided in pairs.

[0011] Furthermore, the two fixing bolts are respectively disposed at both ends of the first adsorption net and the second adsorption net.

[0012] Furthermore, handles are fixedly attached to the first and second adsorption nets respectively.

[0013] Furthermore, the handle is U-shaped.

[0014] Furthermore, the cleaning component includes two cleaning brushes, which are respectively disposed in the mounting box and correspond to the first adsorption net and the second adsorption net respectively. The mounting box is provided with a lifting component and a rotating component.

[0015] Furthermore, the lifting assembly includes a lead screw, with rotating shafts rotatably mounted at both ends of the cleaning brush, and connecting blocks rotatably mounted on the rotating shafts. The connecting blocks are slidably mounted to the mounting box, and the lead screw is rotatably mounted between the two side plates of the mounting box. The lead screw is threadedly connected to the connecting blocks. A servo motor is fixedly connected to the mounting box, and a rotating rod is fixedly connected to the output shaft of the servo motor. A worm gear is fixedly connected to the rotating rod, and a turbine gear is fixedly connected to the lead screw. The worm gear meshes with the turbine gear.

[0016] Furthermore, the rotating component gear is fixedly connected to the rotating shaft, and a rack is fixedly connected to the mounting box, the rack meshing with the gear.

[0017] Furthermore, a stabilizing plate is fixed to the bottom of the support rod.

[0018] The beneficial effect of this application is that it provides a low-NOx emission structure for a vacuum hot water boiler that filters impurities. Attached Figure Description

[0037] The first adsorption mesh 3 and the second adsorption mesh 5 are slidably mounted on the mounting box 2, and connecting pieces 9 are fixedly connected to the first adsorption mesh 3 and the second adsorption mesh 5, respectively. Fixing bolts 10 are threadedly connected to the connecting pieces 9 and are threadedly connected to the mounting box 2. Two connecting pieces 11 and two fixing bolts 10 are provided. The two fixing bolts 10 are respectively located at both ends of the first adsorption mesh 3 and the second adsorption mesh 5. Handles 4 are fixedly connected to the first adsorption mesh 3 and the second adsorption mesh 5, respectively. The handles 4 are U-shaped.

[0038] The cleaning component includes two cleaning brushes 7, which are respectively installed in the mounting box 2 and correspond to the first adsorption net 3 and the second adsorption net 5. The mounting box 2 is equipped with a lifting component and a rotating component.

[0039] The lifting assembly includes a lead screw 20, and two ends of the cleaning brush 7 are respectively rotatably mounted with rotating shafts 21. A connecting block 11 is rotatably mounted on the rotating shaft 21, and the connecting block 11 is slidably mounted with the mounting box 2. The lead screw 20 is rotatably mounted between the two side plates of the mounting box 2, and the lead screw 20 is threadedly connected to the connecting block 11.
