Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly descaling and cleaning of industrial boilers, and in particular to an environmentally friendly descaling and cleaning device for industrial boilers. Background Technology

[0002] Industrial boilers (power generation boilers, steam boilers, etc.) will develop scale and corrosion on their surfaces after a certain period of use due to factors such as the operating environment, water quality, and boiler materials. To ensure the safe and efficient operation of the boiler and to maintain good boiler water (steam) quality, regular inspections are necessary. These inspections should include checking for scale and corrosion on the boiler and its auxiliary systems, and cleaning and descaling are essential.

[0003] Current boiler cleaning and descaling technologies mostly involve prolonged immersion in acidic substances (usually hydrochloric acid and citric acid) followed by rinsing of the boiler body and auxiliary systems. The acid reacts with the scale and rust on the boiler system surface, causing them to dissolve and detach. However, it is difficult to completely remove large areas of stubborn scale and rust. Furthermore, hydrochloric acid and citric acid are corrosive; while the immersion process removes scale and rust, it also causes corrosion to the boiler system. If the acid solution concentration is too high, the corrosive damage to the boiler system can be irreversible.

[0004] Therefore, it is necessary to propose an environmentally friendly descaling and cleaning device for industrial boilers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly descaling and cleaning device for industrial boilers. This device addresses the issue of excessive acid reacting with scale and rust on the boiler system surface, causing them to dissolve and detach. However, it is difficult to completely remove large areas of stubborn scale and rust. Furthermore, hydrochloric acid and citric acid are corrosive, and while they chemically react with scale and rust during the immersion process, they also cause corrosion to the boiler system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly descaling and cleaning device for industrial boilers, comprising a boiler body, an air foaming module disposed inside the boiler body, a drain outlet disposed at the bottom of one side of the boiler body, an interception and adsorption module connected to the drain outlet, a chemical injection and circulation module connected to one side of the interception and adsorption module, a water pump connected to the chemical injection and circulation module, a water supply pipe connected to the water pump, and one end of the water supply pipe extending into the interior of the boiler body;

[0007] The air foaming module includes an aeration pipe and an air compressor. The aeration pipe is located inside the boiler body and has multiple aeration holes along its length. The aeration pipe is connected to a pipe that extends out of the boiler body and is connected to an air compressor at the extended end.

[0008] The chemical dosing circulation module includes a circulating water tank, with a fixed frame fixed in the center inside the circulating water tank. A fan blade is rotatably connected inside the fixed frame, and an injection port is connected to the top of the circulating water tank near the boiler body.

[0009] Preferably, the interception and adsorption module includes a bag filter, the drain outlet is connected to the bag filter, the bag filter is connected to the circulating water tank through a first water pipe, and a second water pipe is connected between the water pump and the circulating water tank.

[0010] Preferably, a burner is fixed to one side of the boiler body, and the boiler body is provided with a space for the flame of the burner to pass through.

[0011] Preferably, the top of the boiler body is provided with a water inlet for the water supply pipe to enter, and a sleeve is slidably fitted on the outside of the water supply pipe. The sleeve is elastic and a fixing screw is embedded in the outside of the sleeve. One end of the fixing screw is pressed against the outside of the water supply pipe, and a baffle plate is fixed at the top of the outside of the sleeve. The bottom end of the baffle plate is attached to the top of the water inlet, and the sleeve is set inside the water inlet.

[0012] Preferably, a detection module is connected to the top of the boiler body, and the detection module includes an endoscope that extends into the interior of the boiler body.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. A circulating filtration device is used to replace acidic cleaning agents with bio-enzymes (prepared by plant fermentation) to perform high-flow circulating flushing of the furnace body. Compressed air is introduced into the boiler to work together with the enzyme grinding particle solution to aerate and flush, enhance the flushing and polishing effect, and accelerate the removal of deposits on the furnace body and pipe walls. Fine polishing and grinding particles are added to the enzyme solution in the circulating water tank to perform high-speed, high-flow grinding on the surface during the cleaning process.

[0015] 2. Real-time endoscopic monitoring: High-definition, waterproof endoscopes can enter all parts of the boiler system (including small pipes) for detection, inspection, photography, and video recording. This provides intuitive photos and videos to understand the internal condition of the boiler and the cleaning results, which can serve as acceptance criteria and archived documentation.

[0016] 3. After the water inside the boiler body is cleaned, the remaining water can be filtered again and enter the circulating water tank. The impact generated when the water flows in will act on the fan blades and cause them to rotate. This allows the water flow inside the circulating water tank to be selected, which speeds up the mixing of water and cleaning agents and increases the discharge speed of the water.

[0017] 4. The sleeve can protect the outside of the water supply pipe, preventing squeezing between the outside of the water supply pipe and the water inlet, which could cause the water supply pipe to bend and slow down the water flow. At the same time, the baffle can provide support between the water supply pipe and the water inlet, and can also seal the top of the water inlet to prevent dust from entering the boiler body.

[0022] This utility model provides, for example Figures 1-3 The illustrated industrial boiler environmentally friendly descaling and cleaning device includes a boiler body 1. An air foaming module is installed inside the boiler body 1. A drain port 14 is located at the bottom of one side of the boiler body 1, connected to an interception and adsorption module. A chemical injection and circulation module is connected to one side of the interception and adsorption module, connected to a water pump 10. The water pump 10 is connected to a water supply pipe 11, one end of which extends into the boiler body 1. A detection module is connected to the top of the boiler body 1, including an endoscope 3. The endoscope 3 is a diving-grade, high-temperature resistant, high-definition endoscope, allowing for real-time detection, inspection, photographing, and video recording inside the boiler body 1, enabling timely monitoring of the internal condition of the boiler body 1 and timely recording and archiving of relevant data.

[0023] The chemical dosing circulation module includes a circulating water tank 9, with a fixed frame 13 fixed in the center inside the circulating water tank 9. A fan blade (or a stirring plate) is rotatably connected inside the fixed frame 13. An injection port 12 is connected to the top of the circulating water tank 9 near the boiler body 1, and a second water pipe is connected between the water pump 10 and the circulating water tank 9.

[0024] During cleaning, environmentally friendly cleaning agent (made from enzymes and bio-fermentation), abrasive particles, and clean water can be added in proportion to the injection port 12 at the top of the circulating water tank 9. The circulating water tank 9 outputs water to the boiler body 1 through the water pump 10. Since the cleaning liquid is injected from the top of the boiler body 1, a certain flushing force is formed, which can better promote the removal of the deposits on the boiler body 1 furnace wall.

[0025] Furthermore, after the water inside the boiler body 1 has been cleaned, the remaining water can be filtered and re-entered into the circulating water tank 9. The impact generated when the water flows in will act on the fan blades and cause them to rotate, thereby allowing the water flow inside the circulating water tank 9 to be selected, accelerating the mixing of the water flow and cleaning agent, and increasing the discharge speed of the water flow.

[0026] Specifically, the air foaming module includes an aeration pipe 4 and an air compressor 6. The aeration pipe 4 is located inside the boiler body 1, and multiple aeration holes 5 are opened along the length direction on the aeration pipe 4. The aeration pipe 4 is connected to a pipe that extends out of the boiler body 1, and the extended end is connected to the air compressor 6.

[0027] The gas generated by the air compressor 6 is connected to the aeration pipe 4 through a pipeline and discharged from multiple aeration holes 5. The compressed air reacts with water to form bubbles. The explosion of the bubbles creates a micro-pressure impact on the inner wall of the boiler body 1, which promotes the shedding of the attached substances.

[0028] The interception and adsorption module includes a bag filter 8 (iron removal filter, equipped with a stainless steel bag filter device, the size of which is selected according to the size of the boiler). While allowing fine abrasive particles to pass through, it filters and adsorbs detached materials and rust in the boiler body, preventing large particles such as metal particles from re-entering the boiler body 1 and causing scratches on the inner surface of the boiler body 1.

[0029] The drain outlet 14 is connected to the bag filter 8, and the bag filter 8 is connected to the circulating water tank 9 through the first water pipe.

[0030] A burner 7 is fixed on one side of the boiler body 1, and a space is provided on the boiler body 1 for the flame of the burner 7 to pass through.

[0031] The boiler body 1 has a water inlet 2 at the top for the water pipe 11 to enter. A sleeve 15 is slidably fitted on the outside of the water pipe 11. The sleeve 15 is elastic and a fixing screw 16 is embedded in the outside of the sleeve 15. One end of the fixing screw 16 is pressed against the outside of the water pipe 11. A baffle plate 17 is fixed at the top of the outside of the sleeve 15. The bottom end of the baffle plate 17 is attached to the top of the water inlet 2. The sleeve 15 is located inside the water inlet 2.

[0032] The sleeve 15 can protect the outside of the water supply pipe 11 to prevent squeezing between the outside of the water supply pipe 11 and the water inlet 2, which would cause the water supply pipe 11 to bend and slow down the water flow. At the same time, the baffle plate 17 can provide support between the water supply pipe 11 and the water inlet 2, and can also seal the top of the water inlet 2 to prevent dust from entering the boiler body 1.
