Description

Technical Field

[0001] The utility model belongs to the technical field related to hot blast stoves, in particular to a split hot blast stove which is easy to install. Background Art

[0002] A hot air furnace is a thermal power machine. Its working principle is to generate high-temperature hot air through fuel combustion, heat the cold air through a grating, and then transport it to the required space, raising the ambient temperature. The specific process includes fuel preparation, fuel combustion, hot air generation, hot air transportation, and hot air discharge.

[0003] The prior art CN114574645A records a multi-vortex column flow low-nitrogen top-fired hot blast furnace, which can effectively solve the problem of preventing the collapse, corrosion and cracking of the hot blast outlet, and improve production efficiency and service life. The burner arch is concentrically placed on the upper part of the burner, and the burner is supported on the support plate of the furnace shell, and is connected to the independent arch at the bottom in a maze. The independent arch at the bottom of the burner independently supports the furnace shell support plate at the bottom of the arch, and is connected to the large wall of the heat storage chamber in a maze structure. The upper part of the side wall of the burner wall is provided with an upper air inlet pipe, a gas inlet pipe in the middle, and a lower air inlet pipe. The burner wall is provided with a gas ring and two air rings alternately opened up and down, which effectively prevent the gas nozzle from falling off, breaking, and shifting, and prevent detonation combustion. It has high production efficiency and long service life.

[0004] The above-mentioned hot blast stove has certain deficiencies when in use. The above-mentioned hot blast stove adopts an integrated structural design. The hot blast stove itself is large in size. The integrated structural design increases the difficulty of transporting the hot blast stove and is not conducive to the subsequent transfer operation of the hot blast stove. It does not have a split combined fixed structure and has a single functionality. Secondly, the traditional hot blast stove uses biomass materials as fuel for combustion and heating operations, which makes it impossible for the hot blast stove to provide continuous heat for a long time, and it is prone to heating interruptions. In addition, the exhaust direction of the hot blast stove cannot be flexibly adjusted, which reduces its flexibility in use. Utility Model Content
