Problems solved by technology

[0005]However, due to the characteristics of biomass itself, such as high moisture, low calorific value, high volatile matter, poor thermal stability, and low ignition point, the moisture content has a relatively large impact on its properties. Prominently, the water content of biomass in the furnace is generally about 45%. When it is directly burned, it will reduce the combustion temperature, increase the loss of exhaust smo

Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0053] see in conjunction Figure 1 to Figure 11 As shown, according to the embodiment of the present invention, the blowing and suction combined material drying system includes: an air duct device, which is provided with air holes; The air part is connected to the air duct device and sucks air to the air duct device. The air holes on the air duct device can be used for blowing air or for sucking air, which is determined according to the structure of the air duct device and the function of the air hole.

[0054] When drying the material, the material can be blown dry and sucked dry alternately, and the high pressure of the blower can make the air flow reach all parts of the material more fully, and conduct more sufficient contact and heat exchange with the material, improving the air ...

Abstract

The invention discloses a blowing and sucking combined material drying system and a control method thereof. The blowing and sucking combined material drying system comprises an air pipe device, an air blowing part and an air sucking part, wherein air holes are formed in the air pipe device; the air blowing part is connected with the air pipe device and blows air to the air pipe device; and the air sucking device is connected with the air pipe device and performs air suction on the air pipe device. According to the blowing and sucking combined material drying system and the control method thereof, the biomass drying efficiency, combustion efficiency and heat stability are improved.

Description

technical field [0001] The invention relates to the technical field of biomass power generation material drying, in particular to a combined blowing and suction material drying system and a control method thereof. Background technique [0002] At present, energy and environmental issues have become the focus of global attention, and energy shortage is one of the main problems that have plagued the development of human society for a long time. Oil, coal, and natural gas are still the main sources of fuel. [0003] With the depletion of fossil energy and the seriousness of environmental problems, the development and utilization of clean and renewable energy has become an urgent issue. Faced with this severe situation, human beings urgently need to find new alternative energy sources and find a way out for sustainable development. In this context, biomass energy is the only renewable energy that can be stored and transported, and its advantages of high-efficiency conversion a...
