Description

Technical Field

[0001] The invention relates to the technical field of boiler slag recovery and reuse, and in particular to boiler slag recovery and reuse equipment. Background Art

[0002] When biomass boilers are burning, a large amount of slag will be produced. These slags also contain a large amount of waste heat. This part of waste heat is usually discarded. If it can be effectively recovered, the energy utilization rate of the entire system can be improved. Moreover, the slag that has been quenched by water can be used to produce cement. The components in the slag contribute to the formation and strength of cement. It can be seen that the recycling and reuse of biomass boiler slag is very necessary.

[0003] For example, Chinese patent publication number CN117128521B, this invention relates to the field of waste heat recovery technology, and specifically discloses a waste heat recovery and heating device for boilers in waste incineration plants, including a waste incineration boiler and an exhaust chimney, a conveying channel is provided at the lower outlet of the waste incineration boiler, a slag waste heat recovery box is provided at the other end of the conveying channel, a mixing component is movably installed inside the slag waste heat recovery box, a three-way pipe is provided inside the slag waste heat recovery box above the mixing component, a support frame is fixedly installed on the bottom surface of the slag waste heat recovery box, a driving component is provided on the upper end surface of the support frame, and the upper end of the driving component is matched with the bottom surface of the mixing component. By providing a slag waste heat recovery box, the slag and external running water can be mixed and then heated by the high temperature of the slag convection water, and the slag can be cooled at the same time, so that the heat in the slag is transferred to the running water, and the waste heat in the slag is recovered. The running water mixed with the filter residue can be connected to the heating pipe for heating after being treated.

[0004] However, the preheat recovery device mentioned above directly connects the heated water to the heating pipe for heating, and the slag usually contains a large amount of metal oxides, such as calcium oxide and magnesium oxide. When the slag comes into contact with water, these oxides will undergo hydrolysis and release hydroxide ions. This will increase the alkaline components in the water, causing the pH value to rise. In an alkaline environment, copper will react with carbon dioxide and water to form basic copper carbonate, which will damage the surface of the copper pipe and cause corrosion.

DETAILED DESCRIPTION

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 8 The present invention provides a technical solution: a boiler slag recovery and reuse device, comprising:

[0035] A water quenching component, which is used to quench the slag and separate the quenched slag from water;

[0036] A pH adjusting barrel 5, which is connected to the water outlet of the water quenching assembly, a support box 10 is fixed to the inner wall of the pH adjusting barrel 5, a moving shell 12 is slidably mounted on the inner walls of both sides of the support box 10, and the inner cavity of the support box 10 between the two moving shells 12 constitutes a detection cavity;

[0037] A vertically adjustable drainage rod 9 is installed through the middle of the support box 10, and a collar 11 is rotatably installed on the inner wall of the detection chamber of the drainage rod 9, and a first connecting rod 13 is rotatably connected between the collar 11 and the two movable shells 12, and a first pipeline 17 is opened inside the drainage rod 9, and the first pipeline 17 connects the detection chamber with the pH adjustment barrel 5, and a pH test pen 23 is installed on the top of the support box 10 located in the detection chamber;

[0038] The regulating component can inject a neutralizing agent into the pH regulating barrel 5 according to the detection result of the pH test pen 23 .

[0039] The existing waste heat recovery device directly connects the heated water to the heating pipe for heating. The slag usually contains a large amount of metal oxides, such as calcium oxide and magnesium oxide. When the slag comes into contact with water, these oxides will undergo hydrolysis and release hydroxide ions. This will increase the alkaline components in the water, causing the pH value to rise. In an alkaline environment, copper will react with carbon dioxide and water to generate basic copper carbonate, which will damage the surface of the copper tube and cause corrosion. Therefore, in this case, the main problem of corrosion of the copper tube surface caused by heated water is solved. The specific methods are as follows:

[0040] When the device is in use, the slag just out of the furnace is introduced into the water quenching component. After the water quenching is completed, the water after the water quenching is separated from the slag, and the water after the water quenching enters the pH adjusting barrel 5. When the water in the pH adjusting barrel 5 reaches a preset height, the water intake is stopped, and the drainage rod 9 is adjusted to move vertically upward through the external structure. In this process, the drainage rod 9 will push the two movable shells 12 in opposite directions through the first connecting rod 13, so that the pressure in the detection chamber is in a negative pressure state, and then the water in the pH adjusting barrel 5 enters the detection chamber through the first pipe 17. When the water level in the detection chamber reaches a preset height, the pen tip of the pH test pen 23 is immersed in the water in the detection chamber to test the pH thereof, and the test result is transmitted to the adjustment component through the external structure, so that the adjustment component injects a neutralizing agent into the pH adjusting barrel 5.

[0041] After the neutralizing reagent is injected into the pH adjusting barrel 5, the drainage rod 9 is moved vertically downward through the external structure. During this process, the drainage rod 9 will pull the two movable shells 12 closer together through the first connecting rod 13, so that the detection chamber is in a high pressure state, and the sample water in the detection chamber is returned to the pH adjusting barrel 5 through the first pipe 17.

[0042] The neutralizing agent is preferably hydrochloric acid, which is a strong acid that can effectively neutralize alkaline substances. Hydrochloric acid will be ionized into hydrogen ions and chloride ions in water, and the hydrogen ions therein will combine with the hydroxide ions produced by the hydrolysis of calcium oxide and magnesium oxide to form water that is extremely difficult to ionize, thereby completing the neutralization reaction and adjusting the pH value of the water in the pH adjustment barrel 5.

[0043] The above process is repeated to complete the entire adjustment process, and the adjusted water is subsequently allowed to enter the heating system, which solves the problem that the water will be weakly alkaline after water quenching, thereby preventing alkaline water from corroding the copper pipe.

[0044] Furthermore, a sliding plate 14 is vertically slidably installed on the inner wall of the movable shell 12, and a second connecting rod 15 is rotatably connected between the sliding plate 14 and the inner bottom of the supporting box 10. When the two movable shells 12 approach each other, the second connecting rod 15 drives the sliding plate 14 to slide upward in the movable shell 12. Through holes are provided on both sides of the movable shell 12 above the sliding plate 14, and one-way valves are installed in the two through holes. Through holes communicating with the internal environment of the pH adjustment barrel 5 are provided on both sides of the inner wall of the supporting box 10.

[0045] Furthermore, after the drainage rod 9 descends to the bottom, the high pressure environment in the detection chamber can still be maintained for a period of time.

[0046] When testing the pH of water in the pH adjusting barrel 5, it is necessary to suck part of the water as a sample from the first pipe 17 into the testing chamber. After the test is completed, the sample water is pressed back from the testing chamber into the pH adjusting barrel 5. However, before the suction, a certain amount of water is accumulated in the first pipe 17 due to the water pressure. During the process of pressing back, this part of water will not be discharged back into the pH adjusting barrel 5, resulting in that this part of water cannot undergo a neutralization reaction. During the second test after neutralization, this part of water will enter the testing chamber together with the water in the pH adjusting barrel 5 and mix, affecting the test results. Therefore, in order to avoid affecting the secondary test results, in this embodiment, the testing chamber needs to ensure that there is no water residue in the first pipe 17 before extracting the sample for the second time. The specific method is as follows.

[0047] refer to Figure 6 When the drainage rod 9 is adjusted upward by the external structure, the two movable shells 12 move away from each other. While moving, the sliding plate 14 will slide downward due to the pulling force given by the second connecting rod 15, so that the sealed chamber formed by the sliding plate 14 and the top of the movable shell 12 is in a negative pressure state, and then the air enters from the through hole away from the drainage rod 9. When the drainage rod 9 moves downward, the sliding plate 14 moves upward, so that the sealed chamber formed by the sliding plate 14 and the top of the movable shell 12 is in a high pressure state, so that the air therein is discharged through the through hole close to the drainage rod 9, thereby compensating for the pressure in the detection chamber, making the liquid discharge amount in the detection chamber greater than the liquid intake amount, and then enabling the water in the first pipe 17 to be completely discharged into the pH adjustment barrel 5 for neutralization;

[0048] It is worth mentioning that since the first pipe 17 is relatively thin, the detection chamber will still be in a high-pressure environment for a period of time after the residual water in the first pipe 17 is discharged, so that the air in the detection chamber is continuously discharged from the first pipe 17, and then the first pipe 17 is dynamically sealed by the airflow, preventing the water in the pH adjustment barrel 5 from entering the first pipe 17 again before the neutralization reaction is completed, and the continuous spraying time of the airflow is the time of the subsequent neutralization reaction, avoiding errors in the second test after neutralization, making the test result more accurate.

[0049] Furthermore, a piston body 18 is fixedly connected to the top of the support box 10, and the top of the drainage rod 9 passes through the piston body 18 and can rotate and move up and down in the piston body 18. An electromagnet 21 is fixedly installed on the top of the piston body 18, and a piston plate 19 slidably installed on the inner wall of the piston body 18 is fixed on the outer wall of the drainage rod 9, and a magnet 20 is fixedly installed on the top of the piston plate 19. A cleaning pipe 22 connected to the inside of the detection chamber is installed at the bottom of the piston body 18, and a one-way valve is installed in the cleaning pipe 22. A second pipe 29 connected to the external water pipe is installed on the inner wall of the piston body 18, and a one-way valve is also installed in the second pipe 29.

[0050] When the preset water level is reached in the pH adjustment barrel 5, the electromagnet 21 will attract the magnet 20 to move upward, thereby driving the drainage rod 9 to move upward. After a pause for a certain period of time when reaching the highest point, the electromagnet 21 will give a repulsive force to the magnet 20, so that the magnet 20 drives the drainage rod 9 back to the bottom, completing the process of adjusting the drainage rod 9 to move up and down and detecting.

[0051] When the electromagnet 21 attracts the magnet 20 to move upward, the magnet 20 drives the piston plate 19 to move, and the closed chamber formed by the piston plate 19 and the bottom of the piston body 18 is in a negative pressure state, so that the water in the external water pipe enters the chamber through the second pipe 29. When the electromagnet 21 repels the magnet 20 so that the magnet 20 drives the piston plate 19 to slide downward, the closed chamber formed by the piston plate 19 and the bottom of the piston body 18 is in a high pressure state, so that the water in the chamber is sprayed on the pen tip of the pH test pen 23 through the cleaning pipe 22, thereby completing the cleaning of the pen tip of the pH test pen 23, preventing the residual water left after the last test from affecting the next test, thereby preventing errors from occurring during the next test, and making the test result more accurate.

[0052] Furthermore, a long gear 25 is fixedly connected to the top of the drainage rod 9, a motor is installed on the top of the pH adjustment barrel 5, and a transmission gear 26 is fixedly connected to the end of the output shaft of the motor, and the long gear 25 is meshed with the transmission gear 26;

[0053] It also includes a stirring tube 8 which is slidably connected to the outer wall of the drainage rod 9 through a spline, and the top of the stirring tube 8 is rotatably connected to the bottom of the support box 10. A plurality of stirring plates 30 are installed on the outer wall of the stirring tube 8, and a plurality of exchange holes 24 are opened at the bottom of the outer wall of the stirring tube 8.

[0054] When water enters the pH adjusting barrel 5 from the water quenching assembly, the transmission gear 26 is driven by the motor, so that the transmission gear 26 drives the long gear 25 and the drainage rod 9 to rotate. Since the drainage rod 9 is connected to the stirring tube 8 by a spline, the rotation of the drainage rod 9 will drive the stirring tube 8 to rotate together, thereby causing the stirring plate 30 to stir the water in the pH adjusting barrel 5, so that the water in the pH adjusting barrel 5 is more uniform.

[0055] During the process of absorbing the sample water, the rotation of the drainage rod 9 will form a vortex rotating around the drainage rod 9 in the detection chamber, so that the sample water can better contact with the tip of the pH test pen 23, thereby making the detection result more accurate.

[0056] After the detection is completed, the sample water in the detection chamber is discharged back into the pH adjustment barrel 5. After the neutralizing agent is injected, the stirring of the stirring plate 30 can make the neutralizing agent more uniform in the water, making the neutralization reaction process faster.

[0057] Furthermore, the outer walls on both sides of the pH adjusting barrel 5 are respectively fixed with a first water tank 4 and a second water tank 6, water pumps are installed in the first water tank 4 and the second water tank 6, and the interiors of the first water tank 4 and the second water tank 6 are connected with the interior of the pH adjusting barrel 5. A water inlet pipe 3 is opened at the top of the first water tank 4, and a water outlet pipe 7 is opened at the bottom of the second water tank 6, and the water outlet pipe 7 is connected to the heating system.

[0058] When the water quenching component completes the water quenching, the filtered water will first enter the first water storage tank 4 through the water inlet pipe 3, and then enter the pH adjustment barrel 5 from the first water storage tank 4. When the water in the pH adjustment barrel 5 is tested, the water in the pH adjustment barrel 5 is discharged into the second water storage tank 6, and then flows into the external heating system from the water outlet pipe 7. In this way, the volume of water in the pH adjustment barrel 5 can be fixed, preventing the pH value test and the subsequent neutralization reaction from being affected by the constantly flowing water, thereby improving the accuracy of the test results and increasing the stability during the reaction.

[0059] It is worth mentioning that an external pipe can be connected to the water outlet pipe 7 and the pipe can be wound around the outer wall of the second barrel 2 in a ring shape to preliminarily dry the slag after water quenching in the second barrel 2 .

[0060] Furthermore, the water quenching assembly includes a horizontally arranged first barrel 1 and an inclinedly arranged second barrel 2, a first conveying dragon is installed in the first barrel 1, a second conveying dragon is installed in the second barrel 2, the discharge port of the first barrel 1 is connected with the feed port of the second barrel 2, a water outlet is opened on the outer wall of the second barrel 2, the water outlet is connected to the water inlet pipe 3, and a filter is provided at the water outlet.

[0061] See also Figure 8 When the slag is discharged from the biomass boiler, it is introduced into the first barrel 1 for water quenching, and then the water after quenching and the slag are introduced into the second barrel 2 through the first conveying dragon. The slag and the water are separated by the filter at the water outlet of the second barrel 2, and the water is introduced into the first water tank 4 from the water inlet pipe 3, and then enters the pH adjustment barrel 5 from the first water tank 4 to complete the above-mentioned detection and pH adjustment process, and the slag is transported upward and discharged through the second conveying dragon for subsequent processing.

[0062] Furthermore, the regulating assembly includes a pH regulator 28 installed on both sides of the supporting box 10, and the pH regulator 28 is connected to the external liquid supply structure.

[0063] When the pH test pen 23 completes the detection of the sample water in the detection chamber, the detection result will be transmitted to the pH regulator 28 , and the pH regulator 28 can inject a neutralizing agent into the pH adjustment barrel 5 according to the detection result of the pH test pen 23 .

[0064] Furthermore, the water level in the detection chamber is always lower than the through hole formed on the outer wall of the moving shell 12 .

[0065] During the detection process, if the water level in the detection chamber is too high, it will not only flow out from the through hole on the outer wall of the movable shell 12, but also cause deviation in the detection result of the pH test pen 23.

[0066] Furthermore, when the drainage rod 9 rises to the highest point, the long gear 25 is disengaged from the transmission gear 26 .

[0067] When the drainage rod 9 rises to the highest point, the long gear 25 is disengaged from the transmission gear 26, and the drainage rod 9 stops rotating, which will calm the sample water in the detection chamber, allowing the pH test pen 23 to better detect it and make the detection result more accurate.

[0068] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
