Description

Technical Field

[0001] This utility model belongs to the field of boiler technology, specifically relating to a temperature-regulating waste heat boiler. Background Technology

[0002] A waste heat boiler is a type of boiler that uses the residual heat from waste gas, waste materials, or waste liquid in various industrial processes, as well as the heat generated from the combustion of combustible substances, to heat water to a certain temperature. Through waste heat recovery, it can produce hot water or steam for use in other processes, resulting in significant energy-saving effects. In order to match the thermal energy parameters generated by the boiler with the requirements of subsequent processes, the temperature of the waste heat boiler needs to be adjusted.

[0003] High-temperature exhaust gas contains fine solid impurities (such as dust, particulate matter, and carbon black particles). Due to the high temperature of the exhaust gas, the filter screen is easily deformed. Usually, the filter screen is used for dust removal after the temperature of the high-temperature exhaust gas decreases. When these impurities encounter cold (heating cold water), they easily condense and deposit inside the lower part of the pipe. However, the existing technology lacks a mechanism for cleaning the pipe. When a large amount of solid impurities are deposited, it can easily cause blockage of the pipe, making the boiler unable to operate normally. Therefore, a technical measure is proposed to solve the problem that the existing technology lacks a mechanism for cleaning the pipe, and that a large amount of solid impurities can easily cause blockage of the pipe, making the boiler unable to operate normally.

The connecting pipe is connected to a box, and the other end of the connecting pipe is connected to an air inlet box. Thanks to the cleaning component, it is convenient to clean the deposited impurities inside the base plate, avoiding pipe blockage and ensuring the normal operation of the furnace body.

[0008] Furthermore, a water inlet pipe is installed at the middle of the top of the furnace body, and a pipe cover is movably installed at the upper end of the water inlet pipe.

[0009] Furthermore, a communication module is installed on the mounting plate, and a data acquisition module is located next to the communication module. The data acquisition module is fixedly installed on the mounting plate and is connected to a temperature sensor located inside the furnace body. A PLC controller is installed on the lower part of the surface of the mounting plate.

[0010] Furthermore, a motor is installed on the upper surface of the box, the motor is connected to a screw, the screw is threadedly connected to a lifting plate, the other end of the lifting plate is slidably connected to a vertical rod, the vertical rod is fixedly installed inside the box, an insert plate is installed in the middle of the lower surface of the lifting plate, the insert plate is slidably adapted to the air intake box, and an air intake pipe is installed on the side of the air intake box away from the connecting pipe.

[0011] Furthermore, two sets of inclined heat-absorbing plates are installed through the upper surface of the bottom plate, and a top plate is connected to the upper end of the heat-absorbing plates. A discharge pipe is installed on the side of the top plate and passes through the furnace body.

[0012] Furthermore, a collection box is slidably provided at the end of the base plate away from the connecting pipe.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention enables remote monitoring of water temperature by incorporating a communication module, a temperature sensor, and a data acquisition module, thereby improving the efficiency and convenience of monitoring. The temperature sensor transmits the temperature signal to the data acquisition module, which processes the data and then transmits it to the communication module, which then sends the data.

[0017] By configuring a PLC controller, communication module, motor, screw, lifting plate, insert plate, and vertical rod, the furnace water temperature can be adjusted. When the preset temperature is reached, it can react quickly and remotely. The temperature control and adjustment speed is fast. The remote transmission of instructions to the communication module is then transmitted to the PLC controller. The PLC controller controls the motor to start and drive the screw to rotate. The rotation of the screw drives the lifting plate to move downward along the vertical rod. The lifting plate slides down and drives the insert plate into the air inlet box, thereby shutting off the entry of high-temperature exhaust gas.

[0018] The cleaning components facilitate the removal of deposits inside the bottom plate, preventing pipe blockage and ensuring normal furnace operation. Pulling the lever outwards activates the scraper to remove deposits from the bottom plate (high-temperature exhaust gas first enters the bottom plate, then the heat absorption plate, and dust deposits fall through the heat absorption plate into the bottom plate), and then the deposits enter the collection box.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a temperature-regulating waste heat boiler, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the furnace includes a furnace body 1. A connecting pipe 11 is installed through the side of the furnace body 1, and the connecting pipe 11 is connected to a base plate 22. The base plate 22 is hollow, and the side of the base plate 22 away from the connecting pipe 11 passes through the furnace body 1. A cleaning component 2 is installed inside the base plate 22. A box 3 is connected through the connecting pipe 11, and an air inlet box 18 is connected to the other end of the connecting pipe 11. A water inlet pipe 9 is installed at the middle of the top of the furnace body 1, and a pipe cover 10 is movably installed on the upper end of the water inlet pipe 9. A drain pipe 5 is installed at the lower end of the side of the furnace body 1, and a valve 6 is installed on the drain pipe 5. An installation plate 8 is installed at the upper end of the side of the furnace body 1, and a base 7 is installed at the bottom of the furnace body 1. A communication module 14 is installed on the installation plate 8, and a data acquisition module 12 is located next to the communication module 14 and is fixedly installed on the installation plate. On the upper part of the mounting plate 8, the data acquisition module 12 is connected to a temperature sensor 15, which is located inside the furnace body 1. A PLC controller 13 is installed on the lower part of the mounting plate 8. A motor 16 is installed on the upper surface of the box body 3, and a screw 21 is connected to the motor 16. The screw 21 is threadedly connected to a lifting plate 17, and a vertical rod 19 is slidably connected to the other end of the lifting plate 17. The vertical rod 19 is fixedly installed inside the box body 3. An insert plate 20 is installed in the middle of the lower surface of the lifting plate 17. The insert plate 20 is slidably adapted to the air inlet box 18. An air inlet pipe 4 is installed on the side of the air inlet box 18 away from the connecting pipe 11. Two sets of inclined heat absorption plates 23 are installed through the upper surface of the bottom plate 22. A top plate 26 is connected to the upper end of the heat absorption plates 23. An exhaust pipe 24 is installed on the side of the top plate 26. The exhaust pipe 24 is through the top plate 26. A collection box 25 is slidably provided at the end of the bottom plate 22 away from the connecting pipe 11, passing through the furnace body 1. When using this boiler, clean water is injected into the furnace body 1 through the water inlet pipe 9, and then the air inlet pipe 4 is connected to the high-temperature exhaust gas. The high-temperature exhaust gas then enters the bottom plate 22 through the air inlet pipe 4, the air inlet box 18, and the connecting pipe 11. When the high-temperature exhaust gas entering the bottom plate 22 encounters cold ash, solid particles are deposited at the bottom of the bottom plate 22. The clean water inside the furnace body 1 absorbs the heat of the high-temperature exhaust gas in the bottom plate 22, and the temperature of the cold water rises (the hot water undergoes convection inside the furnace body 1, that is, the hot water at the bottom of the furnace body 1 moves upward and mixes with the colder water at the top, thus the overall water temperature rises, and the high-temperature flue gas entering the bottom plate 22 has the highest temperature. Subsequently, as it moves upward, the temperature of the high-temperature exhaust gas decreases, and the temperature of the upper part of the furnace body 1... The water temperature is lower in the upper part than in the lower part. A temperature sensor 15 (e.g., a CWDZ31A type temperature sensor) monitors the water temperature. The data acquisition module 12 collects the data and transmits it to a remote computer via the communication module 14, enabling remote monitoring. When the temperature exceeds a predetermined level, temperature control and adjustment are required. Specifically, a remote command is sent to the communication module 14, which in turn sends the command to the PLC controller 13. The PLC controller 13 then starts the motor 16, which drives the screw 21 to rotate. The rotation of the screw 21 causes the lifting plate 17 to move downwards along the vertical rod 19. The lifting plate 17 slides downwards, causing the insert plate 20 to enter the air inlet box 18, thereby closing off the high-temperature exhaust gas and achieving remote temperature control and adjustment.When it is necessary to clean the inside of the base plate 22, cleaning is performed using cleaning component 2.

[0028] Reference Figure 1 , Figure 4 , Figure 5 As shown, the cleaning component 2 includes a pull rod 201, which is connected to a connecting rod 202. The other end of the connecting rod 202 is connected to a ring 204. The lower end of the ring 204 is connected to a vertical plate 205, and the lower end of the vertical plate 205 is connected to a scraper 207. The scraper 207 slides in contact with the interior of the base plate 22 and is inclined. Two sets of symmetrically distributed sliders 206 are installed at the middle position of the side of the vertical plate 205. The sliders 206 are slidably connected to a limit rod 203, which is fixedly installed. Installed inside the base plate 22, pulling the pull rod 201 outward causes the connecting rod 202 to move outward. The outward movement of the connecting rod 202 causes the ring 204, the vertical plate 205, and the slider 206 to move. The movement of the vertical plate 205 causes the scraper 207 to scrape off the deposits inside the base plate 22 (high-temperature exhaust gas first enters the base plate 22, then enters the heat absorption plate 23, and the dust deposits fall into the base plate 22 through the heat absorption plate 23). Then the deposits enter the collection box 25, and the collection box 25 is taken out for processing.

[0029] Working Principle: When using this boiler, clean water is injected into the furnace body 1 through the water inlet pipe 9. Then, the air inlet pipe 4 is connected to the high-temperature exhaust gas. The high-temperature exhaust gas then enters the bottom plate 22 through the air inlet pipe 4, air inlet box 18, and connecting pipe 11. When the high-temperature exhaust gas enters the bottom plate 22 and encounters cold ash, solid particles are deposited at the bottom of the bottom plate 22. The clean water inside the furnace body 1 absorbs the heat from the high-temperature exhaust gas in the bottom plate 22, causing the temperature of the cold water to rise (the hot water undergoes convection inside the furnace body 1, meaning the hot water at the bottom of the furnace body 1 moves upward and mixes with the cooler water at the top, thus raising the overall water temperature; the high-temperature flue gas entering the bottom plate 22 has the highest temperature, and subsequently, as it moves upward, the temperature of the high-temperature exhaust gas decreases, resulting in a lower temperature at the top of the furnace body 1 than at the bottom). The water temperature is monitored by a temperature sensor 15 (e.g., a Xingyi CWDZ31A type temperature sensor 15). The data acquisition module 12 collects the data and transmits it to a remote computer through the communication module 14, enabling remote monitoring. The system monitors the water temperature. When the temperature exceeds a predetermined level, it needs to be controlled and adjusted. Specifically, a remote command is sent to the communication module 14, which in turn sends the command to the PLC controller 13. The PLC controller 13 then starts the motor 16, which drives the screw 21 to rotate. The screw 21 rotates and moves the lifting plate 17 downward along the vertical rod 19. The lifting plate 17 slides downward and moves the insert plate 20 into the air inlet box 18, thereby closing off the high-temperature exhaust gas and achieving remote temperature control and adjustment. Through the configuration of the communication module 14, temperature sensor 15, and data acquisition module 12, remote monitoring of the water temperature is achieved, improving the efficiency and convenience of monitoring. The configuration of the PLC controller 13, communication module 14, motor 16, screw 21, lifting plate 17, insert plate 20, and vertical rod 19 enables the adjustment of the water temperature in the furnace body 1. When the predetermined temperature is reached, a rapid remote response can be made, resulting in fast temperature control and adjustment.

[0030] When it is necessary to clean the inside of the bottom plate 22, the cleaning component 2 is used. Pulling the pull rod 201 outward causes the connecting rod 202 to move outward. The outward movement of the connecting rod 202 causes the ring 204, the vertical plate 205, and the slider 206 to move. The movement of the vertical plate 205 causes the scraper 207 to scrape off the deposits inside the bottom plate 22 (high-temperature exhaust gas first enters the bottom plate 22, then enters the heat absorption plate 23, and the dust deposits fall into the bottom plate 22 through the heat absorption plate 23). Then the deposits enter the collection box 25. The collection box 25 is taken out for processing. The setting of the cleaning component 2 facilitates the cleaning of the deposited impurities inside the bottom plate 22, avoids the pipes from being blocked, and ensures the normal operation of the furnace body 1.
