Technical Field

[0001] The invention relates to the technical field of boilers, in particular to a multi-stage heat exchange boiler energy-saving device with high energy efficiency. Background Art

[0002] As a key equipment for heat energy conversion, boilers play an important role in industrial production and daily life. Boilers are mainly composed of two parts: "pot" and "furnace". The former contains water and other media, and the latter is a place where fuel combustion generates heat. With the development of technology, the energy efficiency and environmental protection performance of boilers are constantly improving, and advanced technologies such as multi-stage heat exchange boiler energy-saving devices have emerged. Traditional boilers have high exhaust gas temperatures, and the water vapor in the flue gas carries a large amount of latent heat that is not utilized, resulting in low energy efficiency. Multi-stage heat exchange technology optimizes the heat exchange process and uses efficient condensation waste heat recovery devices to not only collect sensible heat in high-temperature flue gas, but also recover the latent heat released by condensation of water vapor, thereby significantly improving boiler efficiency and reducing energy consumption and environmental pollution. At the same time, the materials and manufacturing processes of boilers are also constantly improving to adapt to harsher working environments and higher energy efficiency requirements. Among them, multi-stage heat exchange boiler energy-saving devices have also been continuously improved and optimized in terms of corrosion resistance, heat exchange efficiency and equipment management, further improving their energy-saving effects and environmental protection performance; The existing multi-stage heat exchange boiler energy-saving device still has certain defects. In terms of heat exchange efficiency, although the design of multi-stage heat exchange is aimed at improving the heat recovery rate, it may be limited by factors such as material thermal conductivity, heat exchange area and fluid flow state in actual operation, resulting in the heat exchange efficiency being difficult to reach the theoretical maximum value. Compared with the structure of traditional boilers, the structure of multi-stage heat exchange boiler energy-saving devices is more complicated, and regular cleaning of the heat exchange surface and inspection of sealing performance and other maintenance work are required. Problems such as uneven fluid distribution and scaling of the heat exchange surface in the multi-stage heat exchange boiler energy-saving device will affect the stability of operation, and thus affect the overall performance and energy efficiency of the boiler.

However, the above patent cannot achieve the function of uniform distribution of fluid inside the multi-stage heat exchange boiler energy-saving device.

[0006] 4. Patent document CN115342343B discloses a coal-fired boiler energy-saving device and method. The above patent realizes that by spraying granular coal, the fuel is increased to an appropriate amount of suspended combustion, so that the fuel can be burned more fully and effectively in the coal-fired boiler body, thereby improving the efficiency of the coal-fired boiler body during the combustion process, and making the coal-fired boiler body more efficient in the process of fuel combustion. However, the above patent cannot realize the function of locating faults of multi-stage heat exchange boiler energy-saving devices.

[0026] Furthermore, after working for a long time, scale will be generated on the heat exchange surface of the multi-stage heat exchange boiler energy-saving device. The presence of scale reduces the heat exchange efficiency of the heat exchange surface and reduces the energy efficiency of the equipment. The heat exchange surface is cleaned by the reflux cleaning module. The water flow converted into by the condensation of the fluid during the heat exchange process is collected in the water storage tank 3 through the water pipe diversion. When the heat exchange surface needs to be cleaned, water in the water storage tank 3 is extracted to flush the heat exchange surface. The sewage after flushing is collected in the dirty water tank 4 through the water pipe diversion, thereby realizing the self-cleaning function of the multi-stage heat exchange boiler energy-saving device, solving the problems of scaling of the heat exchange surface, regular cleaning of the heat exchange surface and reduced heat exchange efficiency, prolonging the service life of the multi-stage heat exchange boiler energy-saving device, reducing the use of human resources, reducing production costs, and saving water resources.

The transmitting unit transmits sound waves to the hole after the probe 33 is squeezed. The sound waves return after reaching the bottom. The receiving element receives and records the time consumed.

The processor 8 controls the neutralization module 48 to neutralize the internal fluid of the multi-stage heat exchange boiler energy-saving device during operation based on the feedback information received, and extracts the balance liquid in the PH balance tank 49 through the pressure pump 51, and atomizes it through the atomizing head 50 to make it fully mixed with the fluid, thereby reducing the generation of scale and acid corrosion on the heat exchange surface. At the same time, the neutralization module 48 can be connected to the water storage tank 3 through a water pipe, and the heat exchange surface is flushed by adjusting the atomizing head 50, thereby realizing the acid-base balance function of the internal fluid of the multi-stage heat exchange boiler energy-saving device, solving the problems of scale generation and acid corrosion on the heat exchange surface, extending the service life of the equipment, improving the working efficiency of the equipment, and reducing the cost and human resources of maintaining the equipment.

[0032] Working principle: after working for a long time, the heat exchange surface of the multi-stage heat exchange boiler energy-saving device will produce scale. The presence of scale reduces the heat exchange efficiency of the heat exchange surface and reduces the energy efficiency of the equipment. The heat exchange surface is cleaned by the reflux cleaning module. During the heat exchange process, the fluid condenses and converts into water flow, which is collected in the water storage tank 3 through the water pipe diversion. When the heat exchange surface needs to be cleaned, water in the water storage tank 3 is extracted to rinse the heat exchange surface. The sewage after rinsing is collected in the dirty water tank 4 through the water pipe diversion. In the process of cleaning the heat exchange surface, different brush heads 42 need to be selected according to the hardness and thickness of the scale. When the adapter 25 and the converter 26 are driven close to the heat exchange surface by the telescopic component 31, the probe 33 penetrates the scale. The data collected by the resistance sensor 34 and the depth sensor 35 are used to judge the hardness and thickness of the scale on the heat exchange surface in the current state. After the analysis is completed, the processor 8 controls the converter 26 to rotate and selects a suitable brush head 42 to clean the scale on the heat exchange surface. The air tightness of the multi-stage heat exchange boiler energy-saving device directly affects the working efficiency of the equipment. The air tightness of the equipment is detected by the flow sensor 14. The incoming gas pushes the measuring blade to deflect, driving the potentiometer sliding arm on the measuring blade to rotate. When the thrust generated by the gas and the tension of the measuring blade reset spring are balanced, the movement stops. The change in the output voltage on the potentiometer during this period is converted into the gas flow rate by the processing unit. By comparing the flow data, the equipment maintains good air tightness when the error does not exceed 3%; In the operation of the multi-stage heat exchange boiler energy-saving device, the fluid entering through the air inlet 6 is often difficult to be quickly and evenly dispersed on the heat exchange surface. By setting multiple groups of multiple ports, the fluid is evenly distributed on the heat exchange surface in a short time. When the fluid passes through the air inlet 6, the processor 8 controls the air valve 18 to open, and the fluid is ejected from the multiple dispersed jet ports 16 through the air pipe 17 to contact the heat exchange surface; During the operation of the multi-stage heat exchange boiler energy-saving device, the laser imager 7 scans and images the equipment, and displays the information and data on the display screen 2 through the processor 8. During the operation of the equipment, if the equipment fails, the fault location and type will be displayed on the display screen 2 at the first time. For example, if the equipment seal fails during operation, the laser imager 7 scans that the fluid inside the equipment escapes outward at a certain point, transmits the information to the processor 8, determines that there is a problem with the sealing of the equipment, and displays the fault and the location of the fault on the display screen 2.
