Description

Technical Field

[0001] The utility model relates to the technical field of waste heat boilers, in particular to a waste heat boiler for producing chromic acid products. Background Art

[0002] During the production of chromic acid products, high-temperature flue gas is a common byproduct. This flue gas not only carries a large amount of energy but also contains a variety of impurities and pollutants. Traditional production processes typically discharge this high-temperature flue gas directly into the atmosphere, which not only pollutes the environment but also wastes heat energy that could be recycled. With increasingly stringent environmental regulations and the need for cost control, manufacturers urgently need a solution that can effectively recover waste heat, reduce energy waste, and lower pollution emissions to improve overall production efficiency and environmental friendliness.

[0003] However, existing technologies often face problems such as low heat exchange efficiency, difficult equipment maintenance, and poor dust removal. Traditional waste heat boilers are typically simple in design and fail to fully utilize the heat energy in the flue gas to heat water and generate steam, resulting in low waste heat utilization. Furthermore, the waste heat boiler's dust removal system often fails to effectively remove fine particles and harmful gases from the flue gas, resulting in substandard flue gas quality and negative environmental impacts. Furthermore, the cleaning and maintenance of dust removal equipment is cumbersome, prone to equipment blockage and unstable operation, increasing maintenance costs and downtime for businesses. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a waste heat boiler for the production of chromic acid products.

[0006] The dust removal mechanism includes a limit block fixedly connected to the outer wall of the upper end of the smoke outlet pipe, the upper end of the limit block is movably connected to the smoke exhaust pipe, one side of the inner wall of the smoke exhaust pipe is fixedly connected to a fixed block, and one side of the fixed block is fixedly connected to a dust bag.

[0007] As a preferred embodiment, the lower end of the boiler body is fixedly connected to a support foot, the outer wall of the upper end of the boiler body is fixedly connected to a steam pipe, the inner wall of the boiler body is provided with a water storage chamber, the inner wall of the boiler body is fixedly connected to a fixing plate, the outer wall of one side of the boiler body is fixedly connected to a water inlet pipe, and one side of the water inlet pipe is fixedly connected to a control valve.

[0008] As a preferred embodiment, the steam pipe is connected to the water storage cavity provided on the inner wall of the boiler body, and the lower end of the steam pipe is connected to the heat exchange pipe provided on the inner wall of the boiler body.

[0009] As a preferred embodiment, the water inlet pipe is correspondingly connected to the water storage cavity provided on the inner wall of the boiler body, and the water inlet pipe is correspondingly connected to the heat exchange tube provided on the inner wall of the boiler body.

[0010] As a preferred embodiment, two fixing plates are fixedly connected to the inner wall of the boiler body, and the two fixing plates are correspondingly connected to the heat exchange tubes.

[0015] 2. When the utility model is in use, a dust removal mechanism is connected to the outlet of the smoke pipe, which filters the smoke mixed with impurities through the dust bag, effectively removing dust and other harmful substances in the smoke, reducing pollution to the air environment, and meeting environmental protection requirements.

[0016] 3. When the utility model is in use, the exhaust pipe and dust bag in the dust removal mechanism are detachable. When the dust bag is blocked, it can be easily taken out for cleaning or replacement, ensuring the long-term stable operation of the equipment and reducing maintenance costs.

At this time, the cooled flue gas can be discharged through the smoke outlet pipe 8 after heat exchange with the heat exchange pipe 5. However, the flue gas generated by the production is often mixed with impurities. If it is discharged directly, it will pollute the air environment. For this purpose, a dust removal mechanism 9 is connected to the outlet of the smoke outlet pipe 8, wherein the dust removal mechanism 9 includes a limiting block 91, and a groove is provided on the upper end of the limiting block 91. The inner wall is movably connected to a smoke exhaust pipe 92, and a fixed block 93 is fixedly connected to the upper and lower ends of the inner wall of the smoke exhaust pipe 92. The fixed block 93 at the lower end is provided with a groove that is correspondingly connected to the smoke outlet pipe 8. At this time, the smoke outlet pipe 8 can extend between the two fixed blocks 93, and a dust bag 94 is fixedly connected between the two fixed blocks 93.

After long-term use, the dust bag 94 will be blocked and urgently needs to be cleaned. At this time, the smoke exhaust pipe 92 can be removed from the limit block 91, and the dust bag 94 provided therein can be flushed or directly replaced. Example

A water inlet pipe 10 is fixedly connected to the outer wall of one side of the boiler body 1, and a control valve 11 is provided on the outer wall of the water inlet pipe 10, so that water can be transported to the boiler body 1 through the water inlet pipe 10, and the control valve 11 can control the water inlet pipe 10. At this time, a heat exchange tube 5 is provided in the boiler body 1. At this time, the water added to the water storage chamber 6 can perform heat exchange operation with the flue gas transported in the heat exchange tube 5. At this time, the water in the water storage chamber 6 will be heated and boiled to generate water vapor. At this time, the water vapor can be discharged through the steam pipe 3, and then subsequent heat conversion operations are carried out. Two fixed plates 7 are fixedly connected to the inner wall of the boiler body 1. The fixed plates 7 can be connected to the heat exchange tube 5 accordingly, so that the heat exchange tube 5 can be fixed.

At this time, the smoke outlet pipe 8 can extend between the two fixed blocks 93, and a dust bag 94 is fixedly connected between the two fixed blocks 93. The dust bag 94 has the function of absorbing dust, so it can filter the flue gas mixed with impurities and transport the filtered flue gas out through the smoke exhaust pipe 92, thereby playing a role in protecting the environment. After long-term use, the dust bag 94 will be blocked and urgently needs to be cleaned. At this time, the smoke exhaust pipe 92 can be removed from the limit block 91, and the dust bag 94 provided therein can be flushed or directly replaced.
