Description

A boiler furnace for burning chemical waste gas Technical Field

[0001] This utility model belongs to the technical field of boiler equipment, and in particular relates to a boiler furnace that burns chemical waste gas. Background Technology

[0002] In the process of chemical production, a large amount of waste gas is generated. If this waste gas is discharged directly, it will not only cause environmental pollution, but also waste the energy contained therein. As a key piece of equipment for treating chemical waste gas, the furnace of the chemical waste gas boiler is used to introduce the chemical waste gas into the furnace for combustion and use the heat generated by combustion to heat the working fluid, thereby realizing the recovery and utilization of energy.

[0003] In the gas mixing stage of traditional chemical waste gas boilers, the mixing efficiency of waste gas and combustion air in the existing furnace is not high. For example, the common mixing method is to introduce waste gas and air into the furnace separately and rely on natural diffusion for mixing. This method results in uneven gas mixing, making it difficult to quickly form a uniform combustion airflow, leading to incomplete combustion and reduced combustion efficiency. On the other hand, traditional chemical waste gas boilers simply discharge the flue gas directly after combustion without making full use of the waste heat in the flue gas, resulting in low energy utilization. A large amount of heat energy is wasted with the flue gas, increasing the energy costs of enterprises.

[0004] To address these issues, we provide a boiler furnace that utilizes chemical waste gas. Summary of the Invention

[0005] The purpose of this utility model is to provide a furnace for a boiler that burns chemical waste gas. By combining a gas mixing component and a waste heat recovery component, it solves the problem that the traditional gas mixing method in the furnace of a boiler that burns chemical waste gas in the prior art results in uneven gas mixing, difficulty in quickly forming a uniform combustion airflow, and incomplete combustion.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a boiler furnace for burning chemical waste gas, comprising a furnace body, an mounting plate fixedly connected to the surface of the furnace body, a gas mixing component disposed in the middle of the furnace body cavity, a flow guiding component disposed on one side of the furnace body, a waste heat recovery component disposed on one side of the flow guiding component, a combustion plate disposed at the bottom of the furnace body cavity, the gas mixing component including a fixed plate, the surface of the fixed plate being fixedly connected to the inner wall of the furnace body, a cross-shaped gas distribution plate being movably connected to the bottom of the fixed plate, an exhaust hole being opened at the bottom of the cross-shaped gas distribution plate, fans being fixedly connected to both sides of the top of the mounting plate, the air outlet of the fans being connected to one side of the cross-shaped gas distribution plate through a connecting pipe, mounting rods being fixedly connected to both sides of the furnace body cavity, a positioning plate being fixedly connected between the mounting rods, a movable shaft being movably connected to the inner cavity of the positioning plate, and a fan blade being fixedly connected to the bottom of the movable shaft.

[0008] The present invention is further configured such that the flow guiding component includes a flow guiding shell, the bottom of the flow guiding shell is fixedly connected to the top of the mounting plate, and louvers are fixedly connected to the top and bottom of the inner cavity of the flow guiding shell. After the high-temperature flue gas after combustion enters the inner cavity of the flow guiding shell, it is agitated by the louvers, the water vapor is condensed into water droplets and discharged, and the flue gas is discharged through the top of the flow guiding shell.

[0009] The present invention is further configured such that the waste heat recovery component includes a water tank, one side of which is fixedly connected to the surface of the guide shell, and a coil is fixedly connected to the inner cavity of the water tank. A connecting bend is provided on one side of the coil, and the end of the connecting bend away from the coil is connected to the top of the guide shell. An appropriate amount of water is added to the water tank, and the flue gas enters the inner cavity of the coil through the connecting bend. When the flue gas flows through the inner cavity of the bend, the heat in the flue gas heats the coil, and the coil heats the water, thereby recovering and utilizing the heat in the flue gas.

[0010] The present invention is further configured such that a filter cylinder is provided on the top of the water tank, a micro fan is provided on the top of the filter cylinder, and the bottom of the filter cylinder is connected to one side of the coil through a connecting pipe. When the flue gas discharged from the coil passes through the filter cylinder, the impurities in the flue gas are filtered by the filter cylinder. When the micro fan is turned on, the operation of the micro fan can accelerate the flue gas flow rate.

[0011] The present invention is further configured such that a mounting bracket is fixedly connected to one side of the bottom of the mounting plate, and a condensate drainer is fixedly connected to the inner cavity of the mounting bracket. The condensate drainer collects the condensate falling from the louvers and collects it through the condensate drain trough to the bottom drain pipe, and discharges it from the system by gravity or pressure difference.

[0012] The present invention is further configured such that a support base is fixedly connected to both sides of the bottom of the furnace body, and a support pad is fixedly connected to the bottom of the support base. The support pad can increase the friction of the bottom of the support base, so that the support base can stably support the bottom of the furnace body, and the chemical waste gas boiler can be stably placed on the ground.

[0013] The present invention is further configured such that a cover plate is provided at the bottom of the front side of the furnace body, and an installation ring is fixedly connected to the bottom of the furnace body surface. The bottom of the cover plate is located in the inner cavity of the installation ring. By unscrewing the installation bolts at the bottom of the installation ring, the cover plate can be moved upward for disassembly. After the cover plate is disassembled, the relevant components inside the furnace body can be inspected and maintained.

[0014] The present invention is further configured such that a water inlet is provided on one side of the top of the water tank, and a drain pipe is provided at the bottom of one side of the water tank. Water can be added to the inner cavity of the water tank at regular intervals through the water inlet, and the water in the water tank can be discharged by opening the valve in the inner cavity of the drain pipe.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model has the advantages of efficient mixing and complete combustion. Industrial waste gas and combustion-supporting gas are drawn into the cross-shaped gas distribution plate by a fan. The special structure of the cross-shaped gas distribution plate ensures that the two are fully mixed. At the same time, the airflow drives the fan blades to rotate, and the rotating fan blades further improve the mixing efficiency, ensuring that the mixed gas achieves high-temperature and complete combustion in the combustion space at the bottom of the furnace cavity.

[0017] 2. This utility model has advantages in heat energy utilization and purification. The high-temperature flue gas after combustion is heat-recovered through the guide shell and coil to heat the water in the water tank, realizing the secondary utilization of energy and improving the energy utilization rate. The filter cartridge, together with the micro fan, effectively filters the impurities in the flue gas, and the condensate drainer collects and discharges the condensate, thus ensuring the cleanliness of the flue gas emission.

[0027] Specifically: the blower 304 is turned on, and the two blowers 304 respectively draw industrial waste gas and combustion gas into the inner cavity of the cross-shaped gas distribution plate 302. After the industrial waste gas and combustion gas are fully mixed by the cross-shaped gas distribution plate 302, they are discharged through the exhaust hole 303 at the bottom of the cross-shaped gas distribution plate 302.

[0028] Example 2

[0029] Please refer to Figures 1-5. Based on Embodiment 1, the flow guiding assembly 4 includes a flow guiding shell 401. The bottom of the flow guiding shell 401 is fixedly connected to the top of the mounting plate 2. Louvers 402 are fixedly connected to both the top and bottom of the inner cavity of the flow guiding shell 401. The waste heat recovery assembly 5 includes a water tank 501.

A connecting bend 503 is provided on one side of the coil 502. The end of the connecting bend 503 away from the coil 502 communicates with the top of the flow guiding shell 401. The top of the water tank 501... The furnace body 1 is equipped with a filter cartridge, a micro fan at the top of the filter cartridge, and the bottom of the filter cartridge is connected to one side of the coil 502 via a connecting pipe.

The bottom of the cover plate is located in the inner cavity of the mounting ring. A water inlet is provided on one side of the top of the water tank 501, and a drain pipe is provided at the bottom of one side of the water tank 501.

[0030] Specifically: After combustion, the high-temperature flue gas enters the inner cavity of the guide shell 401, where it is agitated by the louvered plate 402. Water vapor condenses into water droplets and is discharged. The flue gas exits through the top of the guide shell 401. An appropriate amount of water is added to the water tank 501. The flue gas then enters the inner cavity of the coil 502 through the connecting bend 503. As the flue gas flows through the bend in the coil 502, the heat in the flue gas heats the coil 502, which in turn heats the water, thus recovering and utilizing the heat from the flue gas.

The system is discharged by gravity or pressure difference. The support pad can increase the friction at the bottom of the support base 9, so that the support base 9 can stably support the bottom of the furnace body 1, and the chemical waste gas boiler can be stably placed on the ground. By unscrewing the mounting bolts at the bottom of the mounting ring, the cover plate can be moved upward for disassembly. After the cover plate is disassembled, the relevant components inside the furnace body 1 can be inspected and maintained. Water can be added to the inner cavity of the water tank 501 at regular intervals through the water inlet. The water in the water tank 501 can be discharged by opening the valve in the inner cavity of the drain pipe.

[0031] The working principle of this utility model is as follows: When the blowers 304 are turned on, the two blowers 304 respectively draw industrial waste gas and combustion-supporting gas into the inner cavity of the cross-shaped gas distribution plate 302. After the industrial waste gas and combustion-supporting gas are fully mixed by the cross-shaped gas distribution plate 302, they are discharged through the exhaust hole 303 at the bottom of the cross-shaped gas distribution plate 302. The airflow drives the fan blades 308 to rotate, and the rotating fan blades 308 further improve the mixing efficiency of the industrial waste gas and combustion-supporting gas. When the combustion plate 6 is turned on, the mixed gas is burned at high temperature in the combustion space at the bottom of the inner cavity of the furnace body 1, generating water vapor and nitrogen. After combustion, the high-temperature flue gas enters the inner cavity of the guide shell 401, and is further agitated by the louvered plate 402. The water vapor condenses into water droplets and is discharged. The flue gas exits through the top of the guide shell 401, enters the inner cavity of the coil 502 through the connecting bend 503, and an appropriate amount of water is added to the water tank 501. The flue gas enters the inner cavity of the coil 502 through the connecting bend 503. When the flue gas flows through the inner cavity of the bent coil 502, the heat in the flue gas heats the coil 502, and the coil 502 heats the water, thereby recovering and utilizing the heat in the flue gas. When the flue gas discharged through the coil 502 passes through the filter cartridge, the impurities in the flue gas are filtered by the filter cartridge. The micro fan is turned on, and the operation of the micro fan can accelerate the flue gas flow speed. The condensate drain 8 collects the condensate falling from the louvered plate 402 and collects it through the condensate drain trough to the bottom drain pipe, and discharges it from the system by gravity or pressure difference.
