Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically a finned tube fuel gas heater for desulfurization systems. Background Technology

[0002] In desulfurization systems, the temperature of fuel gas is one of the key parameters affecting desulfurization efficiency. If the fuel gas temperature is too low, it will lead to a decrease in the activity of the desulfurizing agent, a slowdown in the reaction rate, and even the condensation of liquid water, resulting in equipment corrosion and a deterioration of the desulfurization effect. Finned tube fuel gas heaters can quickly heat the fuel gas to the optimal temperature range required for the desulfurization reaction by enhancing heat transfer.

[0003] Existing devices have small heat exchange areas and slow fuel gas heating rates, making it impossible to quickly reach the optimal temperature range required for the desulfurization reaction. This directly leads to a decrease in the activity of the desulfurizing agent due to insufficient temperature, slowing down the desulfurization reaction rate and affecting the overall desulfurization efficiency. The high thermal resistance not only results in slow heating but also uneven heat transfer, further reducing heat transfer efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a finned tube fuel gas heater for a desulfurization system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a finned tube fuel gas heater for a desulfurization system, comprising a main housing, a first housing installed at the left and right ends of the main housing, a second housing installed at the outer end of the first housing, a fuel gas heating mechanism provided on the surface of the main housing, the first housing and the second housing, and an auxiliary mechanism provided on the surface of the second housing;

[0006] The fuel gas heating mechanism includes finned tube heating tubes installed inside the main housing. Insertion sockets are fixedly connected to the top and bottom of the first housing, and arc-shaped baffles are inserted into the insertion sockets. Diverter plates are installed at both the left and right ends of the main housing. First mounting seats are fixedly connected to the left and right ends of the front and back of the main housing. Second mounting seats are fixedly connected to the left side of the front and back of the first housing. Third mounting seats are fixedly connected to the right side of the front and back of the first housing. Fourth mounting seats are fixedly connected to the left side of the front and back of the second housing. The finned tube heating tubes inside the main housing increase the heat exchange area through their finned structure, enabling rapid heating of the fuel gas to the optimal temperature range required for the desulfurization reaction. This avoids equipment corrosion problems caused by decreased desulfurizer activity, slowed reaction rate, or liquid water condensation due to excessively low temperatures. The first housing is fixed by the insertion sockets. The fixed arc-shaped baffle plate can change the flow path of fuel gas in the shell, prolong the contact time between the airflow and the heating tube, break the flow boundary layer, reduce heat transfer resistance, and further improve heat transfer uniformity and efficiency. The flow distribution plates at both ends of the main shell can evenly distribute the incoming fuel gas to each finned tube heating tube, avoiding uneven heating caused by excessively strong or weak local airflow, and ensuring stable overall heating effect. Both the flow distribution plate and the arc-shaped baffle plate are detachable structures, and the first shell and the second shell also adopt a detachable design. When the heating tube is scaled, the baffle plate is damaged, or the interior needs to be cleaned, there is no need to disassemble the entire equipment. Only the corresponding shell or component needs to be removed for operation, which greatly shortens the maintenance time and reduces maintenance costs. The fuel gas heating mechanism enhances heat transfer efficiency and ensures the desulfurization reaction requirements. The overall detachable design reduces the difficulty of maintenance. The modular connection of each component improves structural stability and adaptability.

[0007] Preferably, both the flow divider plate and the bow-shaped baffle are designed to be detachable, and both the first housing and the second housing are designed to be detachable.

[0008] Preferably, the main housing and the first housing are connected by a first mounting base and a second mounting base, and the first housing and the second housing are connected by a third mounting base and a fourth mounting base.

[0009] Preferably, the auxiliary mechanism includes an air inlet fixedly connected to the right side of the first housing. A connecting seat is mounted on the surface of the air inlet, and a pressure detector and a temperature detector are mounted on the surface of the connecting seat. A Y-type filter is mounted on the right side of the air inlet, and an extended air inlet pipe is mounted on the right side of the Y-type filter. An exhaust pipe is fixedly connected to the left side of the first housing. The Y-type filter mounted on the right side of the air inlet can filter solid impurities in the fuel gas, preventing impurities from entering the main housing and adhering to the surface of the finned tube heating tube, thus avoiding a decrease in heat transfer efficiency or blockage of the heating tube, extending the service life of the core heating component. The pressure detector and temperature detector... The detector can simultaneously monitor the initial temperature and pressure of the fuel gas entering, as well as the temperature and pressure of the gas discharged after heating. By comparing the inlet and outlet temperatures, it can intuitively determine whether the heating effect of the mechanism meets the standard. If the outlet temperature does not reach the threshold, the power of the heating tube can be adjusted in time to avoid affecting the desulfurization efficiency. It can also monitor the airflow pressure inside the shell in real time. If the pressure rises abnormally, it can stop the machine in time for troubleshooting to prevent the equipment from being damaged by overpressure. If the pressure is too low, it can check whether the air intake is normal to avoid heating interruption due to insufficient air supply. The auxiliary mechanism can filter impurities, protect the core heating components, monitor parameters in real time, ensure the safe and stable operation of the system, optimize airflow delivery, and adapt to the system installation scenario.

[0010] Preferably, the air inlet is located on the right side of the main housing, and the exhaust pipe is located on the left side of the main housing. Both the air inlet and the exhaust pipe are provided with a connector, a pressure detector, and a temperature detector.

[0011] Preferably, the first housing is fixedly connected to the bottom of both the front and back sides with support feet, and the main housing is fixedly connected to the left and right ends of the bottom.

[0012] Compared with the prior art, this utility model provides a finned tube fuel gas heater for desulfurization systems, which has the following advantages:

[0013] 1. This desulfurization system uses a finned tube fuel gas heater with a fuel gas heating mechanism. The finned tube heating tubes inside the main shell increase the heat exchange area through the finned structure, which can quickly heat the fuel gas to the optimal temperature range required for the desulfurization reaction. This avoids equipment corrosion problems caused by decreased desulfurizing agent activity, slowed reaction rate, or condensation of liquid water due to excessively low temperatures. The arc-shaped baffle plate fixed by the plug-in seat in the first shell can change the flow path of the fuel gas in the shell, prolong the contact time between the airflow and the heating tube, break the flow boundary layer, reduce heat transfer resistance, and further improve heat transfer uniformity and efficiency. The flow distribution plates at both ends of the main shell can allow the incoming fuel gas to pass through the baffle plate. The incoming fuel gas is evenly distributed to each finned tube heating tube to avoid uneven heating caused by excessively strong or weak local airflow, ensuring stable overall heating effect. The flow divider plate and the bow-shaped baffle are both detachable structures, and the first and second shells are also designed to be detachable. When the heating tubes are scaled, the baffles are damaged, or the interior needs cleaning, there is no need to disassemble the entire equipment. Only the corresponding shell or component needs to be removed for operation, which greatly shortens the maintenance time and reduces maintenance costs. The fuel gas heating mechanism enhances heat transfer efficiency and ensures the desulfurization reaction requirements. The overall detachable design reduces the difficulty of maintenance. The modular connection of each component improves structural stability and adaptability.

[0014] 2. This desulfurization system uses a finned tube fuel gas heater with auxiliary mechanisms. A Y-type filter installed on the right side of the inlet filters solid impurities in the fuel gas, preventing them from adhering to the surface of the finned tube heating tubes after entering the main casing. This avoids reduced heat transfer efficiency or blockage of the heating tubes, extending the service life of the core heating components. Pressure and temperature detectors simultaneously monitor the initial temperature and pressure of the fuel gas entering, as well as the temperature and pressure of the exhaust gas after heating. By comparing the inlet and outlet temperatures, the heating effect of the mechanism can be directly judged. If the outlet temperature does not reach the threshold, the heating tube power can be adjusted in time to avoid affecting the desulfurization efficiency. Real-time monitoring of the airflow pressure inside the casing allows for timely shutdown and troubleshooting if the pressure rises abnormally, preventing overpressure damage to the equipment. If the pressure is too low, the intake can be checked to avoid heating interruption due to insufficient gas supply. The auxiliary mechanisms filter impurities, protect the core heating components, monitor parameters in real time, ensure the safe and stable operation of the system, optimize airflow delivery, and adapt to different system installation scenarios.

The finned tube heating tube 51 inside the main housing 1 increases the heat exchange area through its finned structure, enabling rapid heating of the fuel gas to the optimal temperature range required for the desulfurization reaction. This avoids problems such as decreased desulfurizer activity, slowed reaction rate, or equipment corrosion caused by liquid water condensation due to excessively low temperatures. The first housing 2 is connected to the connector 52... The fixed bow-shaped baffle 53 can change the flow path of fuel gas in the shell, prolong the contact time between the airflow and the heating tube, break the flow boundary layer, reduce heat transfer resistance, and further improve heat transfer uniformity and efficiency. The flow distribution plate 54 at both ends of the main shell 1 can evenly distribute the incoming fuel gas to each finned tube heating tube 51, avoid uneven heating caused by excessively strong or weak local airflow, and ensure stable overall heating effect. Both the flow distribution plate 54 and the bow-shaped baffle 53 are detachable structures, and the first shell 2 and the second shell 3 also adopt a detachable design.

An exhaust pipe 67 is fixedly connected to the left side of the first housing 2. The Y-type filter 65 mounted on the right side of the air inlet 61 can filter solid impurities in the fuel gas, preventing impurities from entering the main housing 1 and adhering to the surface of the finned tube heating tube 51, thus avoiding a decrease in heat transfer efficiency or blockage of the heating tube, and extending the service life of the core heating component.
