Problems solved by technology

In addition, at this stage, some manufacturers have changed the 1.5 million kcal coal-fired stove into a biomass hot blast stove and found that the expected effect is not achieved at all, that is, 300,000 kcal, so the substantial 1.5 million kcal has not yet been designed successfully.
[0005] At present, the 1.5 million kcal hot blast stove is the mainstream equipment for large-scale drying equipment in the market. The existing biomass hot blast stoves are all imported equipment. There is no design case of a fully automated 1.5 million kcal biomass hot blast stove in China. Therefore , we urgently need to design a fully automatic 1.5 million kcal biomass hot air stove with excellent performance is very necessary

Embodiment 1

[0038] see Figure 1-Figure 6 , the present invention provides a technical solution: a fully automatic hot blast stove for coarse bran, comprising a combustion chamber 1 and a heat exchanger 2, the left side of the combustion chamber 1 is provided with a feed lifting device 3, and the right side of the combustion chamber 1 is provided with a feed lifting device 3. There is an automatic ash removal device 4 on the side, a centrifugal dust removal device 5 on the right side of the heat exchanger 2, the combustion chamber 1, the heat exchanger 2, the feed lifting device 3, the automatic ash removal and ash removal Device 4 and centrifugal dust removal device 5 are controlled by PLC+PID intelligent control system.

[0039] The heat exchanger 2 is made of Q235 steel heat exchange tubes, and the heat exchanger 2 is made of Q235 steel heat exchange tubes. The left side of the heat exchanger 2 is provided with an air inlet 201, and the air inlet 201 communicates with the combustion ch...

Embodiment 2

[0042] see Figure 4-Figure 12The present invention provides a technical solution: the inner cavity of the furnace body 1 is made of 6-inch white bricks and T20 refractory bricks, with an inner cavity of φ1860±2mm, and the cross-section of the inner cavity of the furnace body 1 is upwardly inclined by 19°, And the combustion chamber 1 is divided into six sections, of which the first section is the ignition chamber 101, the second to sixth sections are respectively: the second section of the combustion chamber 102, the third section of the combustion chamber 103, the fourth section of the combustion chamber 104, and the fifth section of the combustion chamber 104. Section combustion chamber 105, sixth section combustion chamber 106, the upper end of the second section combustion chamber 102 is provided with a flameout pipe, the flameout pipe is communicated with the flameout fan 10, and the lower end of the second section combustion chamber 102 is provided with an inspection por...

Embodiment 4

[0045] see Figure 11 The present invention provides a technical solution: the feed port 301 of the feed lifting device 3 is set below the combustion chamber 105 of the fifth section, and the feed port 301 and the tangent to the cross section of the furnace cavity are at an elevation angle of 28°. Under the action of the combustion-supporting fan 8, a negative pressure area will be formed at the feed port 301, and the biomass will be sucked in.

Description

technical field [0001] The invention belongs to the technical field of biomass hot blast stove, which is used for rapid drying of rice, corn and the like after harvesting, and in particular relates to a fully automatic hot blast stove for coarse bran. Background technique [0002] In grain-producing areas, rice and corn need to be dried as soon as possible after they are harvested to prevent mildew. Large-scale drying towers in China require large-scale hot blast stoves to provide heat sources. Due to environmental protection issues, the development of large-scale coal-fired and gas-fired hot blast stoves is limited. Grain bran used as fuel for drying grain has great advantages. Burning grain bran is easy to fully burn during the combustion process, and the heat generated is relatively stable and controllable, which meets the requirements for drying grains such as grains, and straw biomass is in the combustion process. Compared with high calorific value fossil fuels such as...
