Embodiment

[0011] Such as figure 1 As shown, a hot blast stove includes a furnace shell 1 and a furnace 2 installed in the furnace shell, the outer wall of the furnace 2 is provided with a water interlayer 3, and the furnace shell is provided with a coal filling port 11 and an ash outlet 12 leading to the furnace , a multilayer superconductor 4 is obliquely installed in the furnace, and the two ends of the superconductor 4 communicate with the water interlayer 3, and an induced draft fan 5 is arranged at the bottom of the furnace 2, and the induced draft fan 5 is connected to the inlet at the top of the furnace through the induced draft duct 6. The tuyere 7 is connected.

[0012] When in use, coal is added through the coal filling port of the boiler, and the coal burns on the superconductor, and the induced draft fan is activated to form a top-to-bottom hot air circulation in the furnace, which reduces the air pollution caused by coal combustion, and passes through the obliquely installe...

Abstract

The invention relates to a hot blast stove, which comprises a shell and a cavity mounted in the shell. The outer wall of the cavity is provided with a water interlayer, the shell is provided with a coal inlet and an ash outlet which are communicated to the cavity, multiple layers of superconductive tubes are mounted in the cavity, two ends of each superconductive tube are communicated with the water interlayer, and a draught fan is arranged on the lower portion of the cavity and connected with an air inlet at the top of the cavity through a draught pipeline. The hot blast stove is simple in structure, high in heat utilization rate and quite low in air pollution, so that environment protection and energy conservation are achieved.

Description

technical field [0001] The invention belongs to the field of boilers, in particular to a hot blast stove. Background technique [0002] With the progress of society, human beings' demand for and destruction of the environment is increasing, which has caused great damage to the natural environment. Due to the destruction of the natural environment, various natural disasters continue to occur, and people gradually realize the importance of the living environment. , and gradually pay attention to the protection of the environment and the efficient use of energy. [0003] The air pollution caused by boiler exhaust gas and how to improve the heat utilization rate of boilers have always been a major problem for technicians in the boiler field. In response to these problems, technicians continue to carry out technological innovations. And environmental protection is still not enough. Contents of the invention [0004] The object of the present invention is to provide a hot blas...
