Warm-air furnace used for high temperature sterilization

Abstract

The invention discloses a warm-air furnace used for high temperature sterilization. The warm-air furnace comprises a boiler, an air cooler, a primary heat exchanger and a secondary heat exchanger, wherein the boiler is composed of a furnace chamber and a heat collection cylinder; the heat collection cylinder is horizontally arranged and communicated with the furnace chamber, the secondary heat exchanger is sleeved outside the heat collection cylinder, the secondary heat exchanger comprises a hair dryer and a warm-air pipe, and the hair dryer is sleeved on the periphery of the heat collection cylinder; a heat interchange channel is formed between the hair dryer and the heat collection cylinder, the outboard of the hair dryer is also provided with a guide wind channel, the warm-air pipe is arranged in the heat exchange channel, and the guide wind channel is communicated with the heat collection cylinder; the primary heat exchanger is composed of a radiating pipe and a cold air channel, and the air inlet of the cold air channel is provided with the air cooler; one end of the heat exchange channel is provided with an air channel which is communicated with the cold air channel around the boiler periphery, the other end of the heat exchange channel is connected with a heat air outlet, and the radiating pipe is communicated with the guide wind channel; and the warm-air furnace provided by the invention has the advantages of simple and reasonable arrangement, and reduces the harm of the coal dust and the dust on staffs, labor cost and the used working capacity, and saves the manufacturing cost.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to a hot blast stove for high temperature sterilization. Background technique [0002] At present, in the production process of edible fungi, high-temperature air is often used to sterilize the medium and culture equipment. At present, coal boilers are commonly used to provide high-temperature gas for sterilization, and while using coal boilers for high-temperature sterilization, a large amount of Coal dust and dust not only fail to achieve the purpose of sterilization, but also further pollute the medium and culture equipment, thereby affecting the growth of edible fungi, reducing the output of edible fungi, and reducing economic benefits, while coal dust and dust are harmful to work. The health of personnel is also harmful to a certain extent. The design of hot blast stoves on the market is complex, difficult to operate, and the heat exchange effect is poor, which increases production costs an...

[0002] At present, in the production process of edible fungi, high-temperature air is often used to sterilize the medium and culture equipment. At present, coal boilers are commonly used to provide high-temperature gas for sterilization, and while using coal boilers for high-temperature sterilization, a large amount of Coal dust and dust not only fail to achieve the purpose of sterilization, but also further pollute the medium and culture equipment, thereby affecting the growth of edible fungi, reducing the output of edible fungi, and reducing economic benefits, while coal dust and dust are harmful to work. The health of personnel also causes harm to a certain extent. The design of hot blast stoves on the market is complex, difficult to operate, and the heat exchange effect is poor, which increases production costs and fails to make full use of heat exchange equipment for heat exchange, thus failing to achieve The effect of sterilization, which wastes energy and increases production costs
