Description

Technical Field

[0001] This utility model relates to the technical field of double-chamber lime kiln furnace structure, and in particular to a segmented brick-protecting plate double-chamber lime kiln furnace structure. Background Technology

[0002] A double-chamber lime kiln is an energy-saving and environmentally friendly device for calcining active lime. It consists of two kiln chambers connected by a channel and employs parallel flow heat storage technology, resulting in higher energy efficiency and better lime quality. Its working principle involves alternating calcination and heat storage in the two kiln chambers, using high-temperature flue gas to preheat uncalcined limestone, thereby reducing energy consumption and improving thermal efficiency. The double-chamber lime kiln protective brick plate is a protective device for the inner wall of the furnace chamber of a double-chamber lime kiln. Its main function is to protect the inner wall of the furnace chamber from the effects of high temperature and corrosion, while ensuring the normal operation of the lime kiln and extending its service life.

[0003] A search revealed that patent announcement number CN211226932U discloses a double-chamber lime kiln with good heat storage effect, comprising two kiln bodies. Each kiln body has an internal heating section. Both kiln bodies are fixedly connected to an insulation layer on their outer sides. Cooling sections are fixedly installed at the bottom of each kiln body, with discharge pipes fixedly installed at the bottom of the cooling sections. Cooling air inlet pipes, penetrating and extending into the discharge pipes, are fixedly installed on opposite sides of the discharge pipes on both sides. A first valve, penetrating and extending into the discharge pipe, is fixedly installed on the outer side of the discharge pipe and below it. Combustion air inlet pipes, penetrating the insulation layer and extending into the kiln bodies on both sides, are fixedly installed on both sides of the insulation layer. This double-chamber lime kiln with good heat storage effect achieves better insulation and heat storage, saving resources and reducing costs, making it more user-friendly.

[0004] However, the existing double-chamber lime kiln furnace is inconvenient to repair when it malfunctions. At the same time, the installation of the protective brick plate inside the double-chamber lime kiln furnace is inconvenient, and it is not easy to disassemble and repair it quickly when the protective brick plate is damaged. Therefore, there is an urgent need in the market for a double-chamber lime kiln furnace structure with segmented protective brick plate to solve these problems. Utility Model Content
