Description

Technical Field

[0001] The invention belongs to the technical field of boiler descaling agents, and particularly relates to a descaling agent for energy-saving boilers. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes forms such as chemical energy in fuel, electrical energy, and thermal energy of high-temperature flue gas. After being converted by the boiler, it outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. Since a lot of scale will be generated during the operation of the boiler, the existence of this scale poses a considerable hazard to the boiler. After the boiler is scaled, it will increase the time, cost, and workload of cleaning and maintenance, affect production, and reduce the effective utilization rate of the boiler.

[0003] The traditional descaling method is to stop using the water-using equipment and adopt inorganic acid pickling. By using the dissolution of inorganic acid on calcium and magnesium salts, the scale in the water-using equipment is removed. The consumption of acid is large, and it seriously corrodes the equipment, reducing the service life of the water-using equipment. At the same time, periodic mechanical cleaning and chemical treatment cause periodic production stoppages, which is not conducive to energy conservation, consumption reduction, and environmental protection.

[0004] A descaling agent is a chemical preparation for removing various scale deposits such as water scale and dirt, and is generally compounded from multiple components. The existing preparation method of boiler descaling agents is generally to directly place a large amount of raw materials in the production equipment and prepare the descaling agent by continuous stirring. This descaling agent preparation method is not conducive to the full mixing of different raw materials, thereby reducing the production quality of the descaling agent. Therefore, we provide a descaling agent for energy-saving boilers and its preparation method to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a descaling agent for energy-saving boilers, which solves the problems in the above background art through the specific structural design of an intermittent feeding component, a mixing tank, a mixing motor, a mixing component, and a pneumatic control component.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a descaling agent for energy-saving boilers, including the following components in parts by weight: 50-60 parts of a multi-component composite, 5-10 parts of sodium thiosulfate, 4-8 parts of a surfactant, 3-5 parts of a corrosion inhibitor, and 2-3 parts of copper oxide;

[0007] Based on the above preparation method of the boiler descaling agent, it includes the following steps:

[0008] S01. Place the multi-component composite in the storage bin on the intermittent feeding component, and the discharge port at the bottom of the storage bin is blocked by a conical plug on the gravity blocking part;

[0009] S02. Deliver air into the arc-shaped cavity through the air control pipeline on the air control component. The air entering the arc-shaped cavity pushes the elastic rotation driving part to move, and controls the rotation of the cam opening and closing part through the moving elastic rotation driving part;

[0010] S03. During the rotation of the cam opening and closing part, the gravity blocking part moves upward under the extrusion of the cam opening and closing part until the conical blocking part releases the blocking of the discharge port at the bottom of the storage bin. At this time, a certain amount of the multi-component composite in the storage bin falls into the mixing tank;

[0011] S04. Control the air control pipeline to release pressure, so that the elastic rotation driving part moves in the reverse direction to drive the cam opening and closing part to rotate in the reverse direction to complete the reset. The gravity blocking part moves downward under the action of gravity to complete the reset. At this time, the conical blocking part re-blocks the discharge port at the bottom of the storage bin;

[0012] S05. Control the mixing component in the mixing tank to rotate to realize the mixing of the multi-component composite and the solvent. After reaching the set mixing time, repeat steps S02 to S04 to continue to realize the feeding and mixing of the multi-component composite;

[0013] S06. Sequentially realize the feeding and mixing of sodium thiosulfate, surfactant, corrosion inhibitor and copper oxide according to steps S01 to S05, and thus complete the preparation of the boiler descaling agent.

[0015] In some embodiments, a radial installation cavity, a radial flow-through cavity and an arc-shaped cavity are formed inside the feeding tray. The radial installation cavity and the radial flow-through cavity are both arranged inside the arc-shaped cavity. One end of the radial flow-through cavity is communicated with the arc-shaped cavity, and the other end of the radial flow-through cavity is communicated with the material guiding pipeline. An air inlet communicated with the arc-shaped cavity is arranged on the circumferential side surface of the feeding tray.

[0016] In some embodiments, the elastic rotation driving part includes a moving disk and a piston disk. The moving disk is slidably matched inside the radial installation cavity. A first limiting groove is formed on the inner wall of the radial installation cavity. A limiting block slidably matched with the first limiting groove is fixed on the circumferential side surface of the moving disk. A first elastic part connected to the moving disk is arranged inside the radial installation cavity. The piston disk is slidably matched inside the radial flow-through cavity, and the moving disk and the piston disk are connected by a linkage rod.

[0017] In some embodiments, the cam opening and closing member includes a protective tube located inside the radial flow passage and sleeved on the linkage rod. A force-bearing rotating member located in the radial flow passage is installed on the protective tube. A spiral groove is provided on the circumferential side of the linkage rod and is located inside the protective tube. A slider fixed to the inner wall of the force-bearing rotating member is fitted in the spiral groove. A cam located inside the material guiding pipe is fixed to the end of the protective tube. The protective tube is rotatably connected to a connection disk fixed to the inner wall of the radial flow passage.

[0018] In some embodiments, the gravity blocking portion includes a gravity reset rod. A conical blocking member is fixed to the circumferential side of the gravity reset rod. A conical force-bearing portion that fits with the cam is fixed to the bottom of the gravity reset rod. A support frame is fixedly arranged on the inner wall of the storage bin. The gravity reset rod is slidably arranged on the support frame. The mixing tank is installed on the bearing frame. A mixing motor is installed at the bottom of the bearing frame. The output end of the mixing motor is connected to a mixing component located inside the mixing tank. A central through opening is provided at the top of the mixing tank. The material guiding pipe is installed inside the central through opening.

[0019] In some embodiments, the pneumatic control assembly includes an L-shaped mounting seat fixed to the outer wall of the mixing tank. An air control pipe communicating with the air inlet is fixed to the outer wall of the mixing tank. A first solenoid valve is installed on the air control pipe. A hollow air push cylinder is communicated with the bottom of the air control pipe. An air discharge pipe is communicated with the top of the hollow air push cylinder. A second solenoid valve is installed on the air discharge pipe. An air supply device is installed on the top of the bearing frame. An air guiding pipe communicating with the hollow air push cylinder is installed at the air outlet of the air supply device.

[0020] In some embodiments, a second limiting groove is provided at the inner bottom of the L-shaped mounting seat. A moving plate is slidably connected inside the second limiting groove. A second elastic member connected to the moving plate is arranged on the inner wall of the L-shaped mounting seat. A guiding rod is slidably arranged inside the hollow air push cylinder. A first triggering portion is fixed to one end of the guiding rod. A second triggering portion is fixed to the other end of the guiding rod. An air push disk located inside the hollow air push cylinder is fixed to the circumferential side of the guiding rod. A first pressure sensor corresponding to the first triggering portion is installed on the inner wall of the L-shaped mounting seat. A signal seat corresponding to the second triggering portion is fixed to the outer wall of the mixing tank. A second pressure sensor is installed on the signal seat.

[0021] The present invention has the following beneficial effects: 1. In the present invention, air flows along the air guide duct into the interior of the hollow air push cylinder, and the air flow pushes the air push plate to move toward the mixing tank. The guide rod that moves synchronously with the air push plate drives the movable plate to move synchronously and stretches the second elastic member. When the second trigger part is pressed against the second pressure sensor, the air push plate just fits the inner end portion of the hollow air push cylinder, and the air flow in the hollow air push cylinder enters the arc cavity along the air control duct and the air inlet. The air entering the radial flow cavity continuously pushes the piston disc to move, and the linkage rod that moves synchronously with the piston disc drives the force-bearing rotating member to rotate. During the rotation of the cam, the cam squeezes the conical force-bearing part to make it move upward, thereby realizing the upward movement of the conical sealing member to release the blockage of the discharge port at the bottom of the storage bin. At this time, part of the raw materials in the storage bin falls into the mixing tank along the guide duct and the guide hopper, thereby realizing intermittent output and mixing of the raw materials in the storage bin.

[0022] 2. After the mixing of some raw materials is completed, the present invention drives the movable plate to move in the opposite direction to complete the reset with the help of the elastic restoring force of the second elastic member, and at the same time drives the movable disk and the piston disk to move in the opposite direction to complete the reset with the help of the elastic restoring force of the first elastic member, and the reverse rotating cam realizes the reset. At this time, the conical blocking member moves down to re-realize the blocking of the discharge port at the bottom of the storage bin, and the air in the arc cavity is discharged along the air inlet and the air control pipeline. The first trigger part is pressed against the first pressure sensor again, and the controller receives the pressure signal from the first pressure sensor and controls the start of the mixing motor. The raw materials and the solvent in the mixing tank are fully mixed by the rotation of the mixing component. After the controller controls the closing of the second solenoid valve and the pressure relief valve on the air control pipeline, it controls the opening of the air supply device and continues to realize the unloading and mixing of some raw materials in the same control method as above until all raw materials in the storage bin are completely unloaded.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Specific Embodiment 1. Please refer to Figures 1-9 , the present invention is a descaling agent for an energy-saving boiler, comprising the following components in parts by weight: 50-60 parts of a multi-component composite, 5-10 parts of sodium thiosulfate, 4-8 parts of a surfactant, 3-5 parts of a corrosion inhibitor, and 2-3 parts of copper oxide;

[0037] Based on the above preparation method of the boiler descaling agent, the following steps are included:

[0038] S01. Place the multi-component composite in the storage bin 104 on the intermittent feeding assembly 1, and the discharge port at the bottom of the storage bin 104 is blocked by the conical blocking member 119 on the gravity blocking part;

[0039] S02. Transport air into the arc-shaped channel 107 through the air control pipeline 702 on the air control assembly 7. The air entering the arc-shaped channel 107 pushes the elastic rotation driving part to move, and controls the rotation of the cam opening and closing part through the moving elastic rotation driving part;

[0040] S03. During the rotation of the cam opening and closing part, the gravity blocking part moves upward under the extrusion of the cam opening and closing part until the conical blocking member 119 releases the blockage of the discharge port at the bottom of the storage bin 104. At this time, a certain amount of the multi-component composite in the storage bin 104 falls into the mixing tank 2;

[0041] S04. Control the air control pipeline 702 to release pressure, so that the elastic rotation driving part moves in the reverse direction to drive the cam opening and closing part to rotate in the reverse direction to complete the reset, and the gravity blocking part moves downward under the action of gravity to complete the reset. At this time, the conical blocking member 119 re-blocks the discharge port at the bottom of the storage bin 104;

[0042] S05. Control the mixing part 5 in the mixing tank 2 to rotate to realize the mixing of the multi-component composite and the solvent. After reaching the set mixing time, repeat steps S02 to S04 to continue to realize the feeding and mixing of the multi-component composite;

[0043] S06. Sequentially realize the feeding and mixing of sodium thiosulfate, surfactant, corrosion inhibitor, and copper oxide according to steps S01 to S05, and thus complete the preparation of the boiler descaling agent.

[0044] Specific Embodiment 2. On the basis of Specific Embodiment 1, such as Figure 7 , Figure 8 and Figure 9As shown in the figure, the intermittent feeding assembly 1 includes a feeding tray 101 installed on the inner wall of the mixing tank 2. A material guiding hopper 102 coaxial with the feeding tray 101 is fixed at the bottom of the feeding tray 101. A material guiding pipe 103 coaxial with the feeding tray 101 is fixed at the top of the feeding tray 101. A storage bin 104 is fixedly installed at the top of the material guiding pipe 103, and the material guiding pipe 103 is communicated with the material guiding hopper 102; a radial installation cavity 105, a radial flow cavity 106 and an arc-shaped cavity 107 are formed inside the feeding tray 101. Both the radial installation cavity 105 and the radial flow cavity 106 are arranged inside the arc-shaped cavity 107. One end of the radial flow cavity 106 is communicated with the arc-shaped cavity 107, and the other end of the radial flow cavity 106 is communicated with the material guiding pipe 103. An air inlet 108 communicated with the arc-shaped cavity 107 is formed on the circumferential side of the feeding tray 101.

[0045] The elastic driving and rotating part includes a moving disk 109 and a piston disk 110. The moving disk 109 is slidably fitted inside the radial installation cavity 105. A first limiting groove 111 is formed on the inner wall of the radial installation cavity 105. A limiting block slidably fitted with the first limiting groove 111 is fixed on the circumferential side of the moving disk 109 (this structure ensures that the moving disk 109 and the piston disk 110 will not rotate during the moving process). A first elastic member 112 connected with the moving disk 109 is arranged inside the radial installation cavity 105. The piston disk 110 is slidably fitted inside the radial flow cavity 106. The moving disk 109 and the piston disk 110 are connected by a linkage rod 113, and the moving disk 109 and the piston disk 110 are always kept in synchronous motion through the linkage rod 113.

[0046] In some embodiments, as Figure 8 shown, the cam opening and closing part includes a protection pipe 114 located inside the radial flow cavity 106 and sleeved on the linkage rod 113. A force-bearing rotating part 115 located in the radial flow cavity 106 is installed on the protection pipe 114. A spiral groove is arranged on the circumferential side of the linkage rod 113 and is located inside the protection pipe 114. A sliding block fixed on the inner wall of the force-bearing rotating part 115 is fitted in the spiral groove. Through this structural design, when controlling the movement of the linkage rod 113, the force-bearing rotating part 115 can be driven to rotate, and then the synchronous rotation of the protection pipe 114 can be realized. A cam 116 located inside the material guiding pipe 103 is fixed at the end of the protection pipe 114. The protection pipe 114 is rotatably connected with a connection disk 117 fixed on the inner wall of the radial flow cavity 106. During the rotation of the protection pipe 114, the gravity blocking part is squeezed by the cam 116 rotating synchronously with the protection pipe 114 to realize the up and down movement of the gravity blocking part.

[0047] Specific Embodiment 3. On the basis of Specific Embodiment 2, as Figure 7 、 Figure 3 and Figure 6As shown in the figure, the gravity plugging part includes a gravity reset rod 118. A conical plugging member 119 is fixed on the circumferential side surface of the gravity reset rod 118. A conical force-receiving part 120 that fits with the cam 116 is fixed at the bottom of the gravity reset rod 118. A support frame 121 is fixedly arranged on the inner wall of the storage bin 104. The gravity reset rod 118 is slidably arranged on the support frame 121. During the process of controlling the rotation of the cam 116, the cam 116 squeezes the conical force-receiving part 120 to make it move up and down, and thus the conical plugging member 119 can block and open the discharge port at the bottom of the storage bin 104; the mixing tank 2 is installed on the bearing frame 3. A mixing motor 4 is installed at the bottom of the bearing frame 3. The output end of the mixing motor 4 is connected to a mixing component 5 located inside the mixing tank 2. A central through port 6 is opened at the top of the mixing tank 2. The guiding pipeline 103 is installed inside the central through port 6. After starting the mixing motor 4, the raw materials and solvents in the mixing tank 2 can be fully mixed through the rotation of the mixing component 5.

[0048] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown in the figure, the pneumatic control component 7 includes an L-shaped mounting seat 701 fixed on the outer wall of the mixing tank 2. An air control pipeline 702 communicating with the air inlet 108 is fixed on the outer wall of the mixing tank 2 (a pressure relief valve is installed on this air control pipeline 702, not shown in the figure). A first solenoid valve 703 is installed on the air control pipeline 702. The bottom of the air control pipeline 702 is communicated with a hollow air push cylinder 704. The top of the hollow air push cylinder 704 is communicated with an air discharge pipe 705. A second solenoid valve 706 is installed on the air discharge pipe 705. A wind supply device 707 is installed on the top of the bearing frame 3. An air guiding pipeline 708 communicating with the hollow air push cylinder 704 is installed at the air outlet of the wind supply device 707; a second limiting groove 709 is opened at the inner bottom of the L-shaped mounting seat 701. A moving plate 710 is slidably connected inside the second limiting groove 709. A second elastic member 711 connected to the moving plate 710 is arranged on the inner wall of the L-shaped mounting seat 701. A guiding rod 712 is slidably arranged inside the hollow air push cylinder 704. A first triggering part 713 is fixedly arranged at one end of the guiding rod 712. A second triggering part 714 is fixedly arranged at the other end of the guiding rod 712. An air push disc located inside the hollow air push cylinder 704 is fixed on the circumferential side surface of the guiding rod 712. A first pressure sensor 715 corresponding to the first triggering part 713 is installed on the inner wall of the L-shaped mounting seat 701. A signal seat 716 corresponding to the second triggering part 714 is fixed on the outer wall of the mixing tank 2. A second pressure sensor 717 is installed on the signal seat 716. In the initial state, the first triggering part 713 is pressing against the first pressure sensor 715, and at this time the second elastic member 711 is in a natural state.

[0049] A certain amount of raw materials is placed in the storage bin 104 and supported by the conical blocking member 119, and then the electrical equipment of the entire device is started. At this time, the controller receives the pressure signal from the first pressure sensor 715, and then controls the air supply device 707 to start (simultaneously opening the first solenoid valve 703) so that the air flow enters the inside of the air push cylinder 704 along the air guide duct 708. The air flow entering the air push cylinder 704 pushes the air push plate to move closer to the mixing tank 2. The guide rod 712 that moves synchronously with the air push plate drives the moving plate 710 to move synchronously and stretch the second elastic member 711. At this time, the pressure signal from the first pressure sensor 715 on the controller disappears. When the second trigger part 714 presses on the second pressure sensor 717, the air push plate just fits in the middle. At the inner end of the air push cylinder 704, the controller receives a pressure signal from the second pressure sensor 717 and starts timing. During this period, the air flow in the air push cylinder 704 enters the arc cavity 107 along the air control pipe 702 and the air inlet 108. The air entering the radial flow cavity 106 continuously pushes the piston disk 110 to move. The linkage rod 113 that moves synchronously with the piston disk 110 drives the force-bearing rotating part 115 to rotate. During the rotation of the cam 116, the cam 116 squeezes the conical force-bearing part 120 to make it move upward, thereby realizing the upward movement of the conical blocking part 119 to release the blockage of the bottom discharge port of the storage bin 104. At this time, part of the raw materials in the storage bin 104 fall into the mixing tank 2 along the material guide pipe 103 and the material guide hopper 102.

[0050] When the first period is over, the controller controls to open the second solenoid valve 706 and close the air supply device 707, and at the same time opens the pressure relief valve on the air control pipeline 702. At this time, the elastic restoring force of the second elastic member 711 drives the movable plate 710 to move in the opposite direction to complete the reset. At the same time, the elastic restoring force of the first elastic member 112 drives the movable disk 109 and the piston disk 110 to move in the opposite direction to complete the reset. The reverse rotating cam 116 is reset. At this time, the conical blocking member 119 moves downward to re-block the discharge port at the bottom of the storage bin 104. The air in the arc cavity 107 is discharged along the air inlet 108 and the air control pipeline 702. The first trigger unit 713 The first pressure sensor 715 is pressed again, and the controller receives the pressure signal from the first pressure sensor 715 and controls to start the mixing motor 4 (while timing the second time period), and the raw materials and the solvent in the mixing tank 2 are fully mixed through the rotation of the mixing component 5. After the second time period ends, the controller first controls to close the second solenoid valve 706 and the pressure relief valve on the air control pipeline 702, and then controls to open the air supply device 707 and continue to implement the unloading and mixing of part of the raw materials in the same control method as above, until a certain raw material in the storage bin 104 is completely unloaded, and then the mixing preparation of other raw materials is implemented in the same control method as above.
