Description

Technical Field

[0001] This utility model relates to the technical field of organic heat carrier boilers, specifically to an explosion relief device for organic heat carrier boilers with self-testing function. Background Technology

[0002] Organic heat carrier boilers generally refer to thermal oil boilers. Thermal oil boilers are boilers that utilize thermal oil for heating. Thermal oil, also known as organic heat carrier or heat transfer medium oil, has been used as an intermediate heat transfer medium in industrial heat exchange processes for over fifty years. These are once-through boilers developed based on the forced circulation design concept. They typically use coal, oil, or gas as fuel and thermal oil as the medium. A circulating oil pump forces the medium to circulate in the liquid phase, transferring heat energy to the heat-using equipment before returning it to the heating furnace for reheating. They can achieve high operating temperatures at low pressures and allow for highly precise control of the medium's operation.

[0003] A search revealed that a typical example of an existing organic heat carrier boiler is disclosed in CN206540309U. This organic heat carrier boiler includes a furnace body. A cylindrical combustion chamber is located in the middle of the upper part of the furnace body's inner cavity. The bottom of the combustion chamber is sealed to the inner wall of the furnace body, thus dividing the interior of the furnace body into an upper heat exchange chamber and a lower preheating chamber. A heat exchange coil is located in the middle of the lower preheating chamber. A groove is located on one side of the bottom of the upper heat exchange chamber. The top of the heat exchange coil is connected to the bottom groove of the upper heat exchange chamber, and the bottom of the heat exchange coil is connected to an oil inlet pipe on the side of the bottom of the furnace body. An oil outlet is located on one side of the top of the upper heat exchange chamber. This organic heat carrier boiler uses heat exchange oil for heat exchange, which is safer and has higher heat exchange efficiency compared to traditional water heat exchange. The boiler volume is significantly reduced, improving plant utilization efficiency.

[0004] In summary, existing organic heat carrier boilers often fail to provide timely explosion relief, leading to boiler body explosions and damage, which affects operational safety. To address these issues, improvements to the existing equipment are necessary. Utility Model Content

[0005] The purpose of this utility model is to provide an explosion relief device for organic heat carrier boilers with self-testing function, so as to solve the problem mentioned in the background art that existing organic heat carrier boilers often cannot achieve explosion relief in time, which leads to easy explosion and damage of the boiler body and affects the safety of use.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the explosion relief device for organic heat carrier boilers with self-testing function,

[0013] To address the issue that existing organic heat carrier boilers often fail to achieve timely explosion relief, leading to boiler body explosions and damage that compromises safety, this application utilizes a pressure detector to monitor the internal pressure of the boiler body in real time. When the pressure becomes excessive, the corresponding first or second exhaust check valve is opened, allowing gas to be transported through the first or second exhaust pipe, a three-way solenoid valve, and a delivery pipe to the explosion relief box. The gas pressure is then increased by a booster, causing the automatic pressure relief assembly to open under the pressure, thereby relieving pressure and improving operational safety.

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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an explosion relief device for an organic heat carrier boiler with self-testing function, based on... Figure 1 and Figure 2 As shown, the upper ends of the corresponding support frames 102 are connected to the middle of both sides of the boiler body 1 via mounting columns 101, and the lower ends of the two support frames 102 are connected to the upper ends of the base 103 on both sides. The mounting columns 101, support frames 102, and base 103 are used together to facilitate the support and fixation of the boiler body 1. An inlet pipe 104 and an outlet pipe 106 are respectively provided at the upper and lower ends of one side of the boiler body 1. The inlet pipe 104 and the outlet pipe 106 are located inside the boiler body 1 and connected by a heat exchange pipe 105. At the same time, a partition plate 107 is provided inside the boiler body 1 in the middle of the heat exchange pipe 105. Pressure detectors 108 are symmetrically arranged on the front of the boiler body 1 with respect to the partition plate 107. The pressure detector 108 facilitates real-time monitoring of the pressure in the two cavities inside the boiler body 1. The other side of the boiler body 1 is connected to the explosion relief assembly 6 via a connecting component. The connecting component includes a first exhaust pipe 2, a second exhaust pipe 3, a three-way solenoid valve 4, and a delivery pipe 5. One end of the first exhaust pipe 2 and the second exhaust pipe 3 are respectively connected to the upper and lower ends of one side of the boiler body 1. The first exhaust pipe 2 and the second exhaust pipe 3 are respectively equipped with a first exhaust check valve 201 and a second exhaust check valve 301. At the same time, the other end of the first exhaust pipe 2 and the second exhaust pipe 3 are connected to both sides of the three-way solenoid valve 4. The front center of the three-way solenoid valve 4 is connected to one side of the explosion relief box 601 via the delivery pipe 5.

[0021] In use, the pressure detector 108 at the upper end detects the internal pressure of the upper cavity. When the pressure value is too high, the first exhaust check valve 201 is opened, allowing the gas inside the upper cavity to be transported to the three-way solenoid valve 4 through the first exhaust pipe 2, and then to the explosion relief box 601 for pressure relief through the delivery pipe 5. The pressure detector 108 at the lower end detects the internal pressure of the lower cavity. When the pressure value is too high, the second exhaust check valve 301 is opened, allowing the gas inside the upper cavity to be transported to the three-way solenoid valve 4 through the second exhaust pipe 3, and then to the explosion relief box 601 through the delivery pipe 5.

[0022] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the explosion relief assembly 6 is installed in the middle of the front of the boiler body 1. The explosion relief assembly 6 includes an explosion relief box 601, a guide funnel 602, a return pipe 603, a pressure booster 604, and a jet nozzle 605. The guide funnel 602 is located in the middle of the explosion relief box 601, and the return pipe 603 is located at the lower end of the other end of the guide funnel 602. The pressure booster 604 is installed on the return pipe 603. Through the pressure booster 604, the pressure of the gas during gas discharge is adjustable, thereby controlling the discharge speed. The other end of the return pipe 603 passes through the guide funnel 602 and extends to the upper end of the guide funnel 602 to connect with the jet nozzle 605. At the same time, an automatic pressure relief assembly is installed on the outside of the jet nozzle 605. Through the automatic pressure relief assembly, the speed and magnitude of the gas discharge pressure can be automatically adjusted according to the gas pressure when the gas entering the explosion relief box 601 is discharged, thereby improving the practicality of use.

[0023] Specifically, the automatic pressure relief assembly includes a limiting channel 606, which is symmetrically arranged with respect to the through hole at the upper end of the explosion relief box 601. The lower limiting channel 606 is located outside the jet head 605. A positioning ring seat 607 is provided inside the through hole, and a rubber plug 608 is engaged in the middle of the positioning ring seat 607. A ventilation screen 609 is provided above the rubber plug 608, and the upper end of the ventilation screen 609 passes through the middle of the limiting plate 610 and connects to the top cover 612. The top cover 612 is located below... The end is fitted to the top of the upper limit channel 606, and the limit plate 610 is set in the middle of the upper limit channel 606. The ventilation screen 609 is located on both outer ends of the limit plate 610 and is fitted with buffer return springs 611. The other side of the two buffer return springs 611 is connected to the upper end of the rubber plug 608 and the lower end of the top cover 612, respectively. Through the buffer return springs 611, the ventilation screen 609 automatically resets under no pressure, so that the top cover 612 seals the limit channel 606.

[0024] In use, gas is delivered to the explosion relief box 601 through the delivery pipe 5, and then enters the return pipe 603 through the guide funnel 602. The booster 604 is activated to pressurize the gas, which is then ejected through the jet nozzle 605. The pressurized gas then impacts the rubber plug 608, causing it to separate from the positioning ring seat 607. Under the action of the gas, the rubber plug 608 is suspended above the positioning ring seat 607. At the same time, the ventilation screen 609 pushes the lower end of the top cover 612 to separate from the top of the upper limit channel 606, opening the limit channel 606. Then, the gas enters the lower end of the ventilation screen 609 and is discharged from the upper end of the ventilation screen 609, thereby relieving pressure and preventing explosion.
