Description

Technical Field

[0001] This utility model relates to the field of stretch filter membrane processing technology, and in particular to a heating temperature control device for a biomass boiler deaerator. Background Technology

[0002] In today's energy sector, biomass boilers, as devices utilizing renewable biomass energy, are widely used in industrial production and heating due to their environmental friendliness and energy-saving characteristics. During the operation of a biomass boiler, the deaerator is a crucial component. Its main function is to remove dissolved oxygen from the water, prevent corrosion of the boiler equipment, thereby extending the equipment's service life and ensuring the safe and stable operation of the boiler.

[0003] Currently, traditional biomass boiler deaerators have some significant shortcomings in heating and temperature control. On the one hand, their steam flow control methods are rather crude. Most rely on simple valve controls, making it difficult to precisely adjust according to the actual water temperature inside the deaerator. This results in a mismatch between the amount of steam supplied and the deaeration requirements. This not only wastes energy and increases operating costs, but also, under certain operating conditions, insufficient or excessive steam supply may affect the deaeration effect and reduce the deaerator's efficiency.

[0004] On the other hand, the monitoring and protection mechanisms for deaerator water temperature are not perfect. In some existing deaerators, although temperature monitoring devices are installed, when the water temperature is abnormal, such as exceeding the upper limit of the safe operating temperature of the feed water pump, timely and effective automatic adjustment cannot be achieved. This can easily lead to problems such as feed water pump cavitation, which in turn affects the normal operation of the entire biomass boiler system and may even lead to equipment damage and safety accidents.

[0005] Therefore, it is necessary to design a heating temperature control device for a biomass boiler deaerator to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heating temperature control device for a biomass boiler deaerator. Through the installation of a temperature sensor, adjustment components, and interlocking control with the controller, it can achieve precise temperature control, effectively prevent cavitation of the feed water pump, save energy, and has good sealing performance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A heating temperature control device for a biomass boiler deaerator includes a deaerator body. Two connectors are located on the right side of the deaerator body, and a three-way pipe is located on the right side of each connector. An adjustment component is located on the right side of the three-way pipe. A temperature sensor is installed at the upper end of the deaerator body, with its sensing end extending into the deaerator body. The adjustment component includes a rectangular box with an opening. Horizontal pipes are located on both sides of the opening. An adjustment block is slidably connected and sealed inside the rectangular box. An electromagnetic plate is located inside the rectangular box, and the adjacent sides of the electromagnetic plate and the adjustment block are elastically connected by springs.

[0009] Preferably, a threaded sleeve is fixedly connected to the upper end of the electromagnetic plate, and a threaded rod is threadedly connected to the threaded sleeve. The upper end of the threaded rod extends to the outside and is fixedly connected to a knob.

[0010] Preferably, the tee pipe includes a main pipe and two branch pipes, the outer walls of the two branch pipes and the connector are provided with a threaded layer, and each connector and the corresponding branch pipe are threadedly connected with a threaded connecting sleeve.

[0011] Preferably, a second flange is fixedly connected to the right side of the main pipe, and a first flange is fixedly connected to the opposite sides of the two horizontal pipes.

[0012] Preferably, a controller is provided on the rear side of the deaerator body, the temperature sensor is electrically connected to the controller via a conductive wire, and the controller is electrically connected to the electromagnetic plate via a wire.

[0013] Preferably, a sealing rubber layer is fixedly connected to the lower end of the adjusting block.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] Compared with existing technologies, this device adopts an interlocking control method that combines a temperature sensor with a controller and an electromagnetic plate. It can monitor the water temperature inside the deaerator in real time and accurately, and automatically adjust the current of the electromagnetic plate according to the water temperature changes. Then, through the interaction of electromagnetic force and spring force, it can precisely control the position of the regulating block to achieve precise regulation of steam flow. This ensures that the amount of heated steam is precisely matched with the deaeration requirements, which significantly improves the deaeration effect and working efficiency. Traditional technologies often cannot achieve such precise control.

[0016] Compared with existing technologies, the structural design of the tee pipe, connector, and threaded connection sleeve of this device makes the connection between the components more stable and easier to install and disassemble, thus improving the practicality and maintainability of the device.

[0017] Compared with existing technologies, the combination structure of the threaded sleeve, threaded rod and knob on the upper end of the electromagnetic plate of this device allows the operator to easily adjust the position of the electromagnetic plate manually according to the actual working conditions, thereby adjusting the initial position of the adjustment block. This enables the device to better adapt to different operating conditions and increases the flexibility and adjustability of the device. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3A temperature control device for a biomass boiler deaerator includes a deaerator body 1. Two connectors 2 are located on the right side of the deaerator body 1, used to connect to external pipes to introduce steam or other media into the deaerator body 1. These connectors are crucial for connecting the deaerator to external systems. A three-way pipe 3 is located on the right side of the two connectors 2, and an adjustment component is located on the right side of the three-way pipe 3. The adjustment component is key to accurately controlling the steam flow rate into the deaerator body 1, adjusting the steam intake according to the actual needs within the deaerator. A temperature sensor 5 is installed at the upper end of the deaerator body 1, monitoring the water temperature inside the deaerator body 1 in real time and providing accurate temperature data for the entire temperature control system. The sensing end of the temperature sensor 5 extends into the deaerator body 1. The adjustment component includes a rectangular box 6 with an opening 13. Horizontal pipes 7 are located on both sides of the opening 13. An adjustment block is slidably connected inside the rectangular box 6. 9. An electromagnetic plate 14 is installed inside the rectangular box 6. The adjusting block 9 is magnetic. When the electromagnetic plate 14 is energized, it generates a magnetic field. The magnetic field interacts with the adjusting block 9, thereby controlling the sliding of the adjusting block 9. The adjacent sides of the electromagnetic plate 14 and the adjusting block 9 are elastically connected by a spring 15. A second flange is fixedly connected to the right side of the main pipe. The opposite sides of the two horizontal pipes 7 are fixedly connected to a first flange 8. The first flange 8 and the second flange facilitate the installation of the adjusting assembly on the tee pipe 3 and other pipes. A controller is installed on the rear side of the deaerator body 1. The temperature sensor 5 is electrically connected to the controller through a conductive connection. This connection method can ensure that the temperature signal is transmitted to the controller quickly and accurately, so that the controller can react in time. The controller and the electromagnetic plate 14 are electrically connected through a wire. The wire transmits the control signal of the controller to the electromagnetic plate 14, thereby realizing the control of the electromagnetic plate 14 and adjusting the position of the adjusting block 9. A sealing rubber layer is fixedly connected to the lower end of the adjusting block 9.

[0024] The upper end of the electromagnetic plate 14 is fixedly connected to a threaded sleeve 12, and a threaded rod 11 is threadedly connected to the threaded sleeve 12. The upper end of the threaded rod 11 extends to the outside and is fixedly connected to a knob 10. The knob 10 is convenient for manual operation by the operator. By rotating the knob 10, the position of the threaded rod 11 can be easily adjusted, thereby changing the position of the electromagnetic plate 14, so that manual adjustment can be performed.

[0025] The three-way pipe 3 includes a main pipe and two branch pipes. The outer walls of the two branch pipes and the connector 2 are all provided with threaded layers. Each connector 2 and the corresponding branch pipe are connected by a threaded connecting sleeve 4, which facilitates the disassembly and installation of the three-way pipe 3 and the adjustment assembly from the deaerator body 1.

[0026] The functional principle of this invention can be explained through the following operation: During the operation of the biomass boiler, the water in the deaerator body 1 needs to be deoxygenated while ensuring that the water temperature is within a suitable range. The temperature sensor 5 senses the water temperature in the deaerator body 1 in real time and transmits the temperature signal to the controller at the rear of the deaerator body 1.

[0027] When the water temperature inside the deaerator body 1 is lower than the set suitable temperature, the controller receives a temperature signal and increases the current supplied to the electromagnetic plate 14. The energized electromagnetic plate 14 generates a magnetic field, which attracts the regulating block 9. Since the electromagnetic plate 14 and the regulating block 9 are elastically connected by a spring 15, the magnetic force overcomes the spring force of the spring 15, causing the regulating block 9 to slide sealed within the rectangular box 6 and move closer to the electromagnetic plate 14. This increases the flow area of ​​the opening 13, increasing the amount of heating steam flowing in from the three-way pipe 3. More steam enters the deaerator body 1 to heat the water, raising its temperature.

[0028] The operator can also rotate the knob 10 to drive the threaded rod 11 to rotate inside the threaded sleeve 12, thereby fine-tuning the position of the electromagnetic plate 14 and adjusting the initial position of the adjusting block 9 to better adapt to different operating conditions.

[0029] If the water temperature inside the deaerator body 1 is too high, reaching the upper limit of the feedwater pump cavitation temperature (e.g., 108℃), the controller will automatically reduce the current supplied to the electromagnetic plate 14. The magnetic force of the electromagnetic plate 14 will weaken, and the elastic force of the spring 15 will push the adjusting block 9 to slide away from the electromagnetic plate 14. The flow area of ​​the inlet 13 will decrease, and the amount of steam entering the deaerator body 1 will decrease, thus preventing the water temperature from continuing to rise and preventing the feedwater pump inlet pressure from falling below the saturation pressure and causing vaporization, thereby protecting the safe operation of the feedwater pump.

[0030] The three-way pipe 3 connects to the connector 2 on the right side of the deaerator body 1 via the main pipe and two branch pipes. The threaded layer on the outer wall of the branch pipe and the connector 2 cooperates with the threaded connection sleeve 4 to achieve a stable and easy-to-disassemble connection.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
