Embodiment Construction

[0010] figure 1 As shown: the yellow phosphorus electric furnace is provided with a complete thermal insulation outer layer 2 on the periphery and top of the furnace body 1, and a closed vacuum thermal insulation space 5 that can be pumped is formed between the two. There is an exhaust pipe port 3 which can be connected with a vacuum pump. A plurality of support piles 4 are distributed between the furnace body 1 and the thermal insulation outer layer 2 .

[0011] During specific implementation, the thermal insulation outer layer can be processed by a steel plate with a thickness of 8 mm, and welded by an automatic welding machine protected by carbon dioxide gas. The separation distance of the heat preservation space 5 between the furnace body 1 and the heat preservation outer layer 2 is preferably 100mm, and the separation distance of the heat preservation space 5 between the furnace bottom 1 and the heat preservation outer layer 2 is preferably 200mm. The insulation space 5...

Abstract

The invention provides a yellow phosphorus electric furnace provided with a vacuum heat preservation outer layer. According to the yellow phosphorus electric furnace, the complete heat preservation outer layer is arranged below a furnace bottom, on the periphery of a furnace body and above a furnace cover. A sealed vacuum heat preservation space of which air can be exhausted is formed between the vacuum heat preservation outer layer and the yellow phosphorus electric furnace. One side of the heat preservation outer layer is provided with an air exhaust pipe opening capable of being connected with a vacuum pump, and a plurality of supporting piles are distributed between the furnace body and the heat preservation outer layer. When the yellow phosphorus electric furnace is used after being installed, the air exhaust pipe opening can be connected with the vacuum pump in a butt joint mode, then the air in the heat preservation space can be exhausted completely through the vacuum pump, and the complete vacuum heat preservation outer layer is formed. Thus, in the internal high-temperature operating state of the yellow phosphorus electric furnace, heat loss can be reduced, energy saving and consumption reducing can be facilitated, and economic benefits can be improved.

Description

technical field [0001] The invention relates to a yellow phosphorus electric furnace, in particular to a yellow phosphorus electric furnace provided with a vacuum insulation outer layer. Background technique [0002] Yellow phosphorus electric furnace is a kind of equipment with high power consumption. In recent years, through the promotion of energy-saving and consumption-reducing technological transformation measures, the best level of electric energy per ton of yellow phosphorus production is still around 14000kwh, but according to the theoretical power consumption calculation of yellow phosphorus production , the power consumption per ton of yellow phosphorus production is 6420kwh, and the excess energy consumption in actual production is due to electric heat loss and various side reactions. According to calculations, the external temperature loss of the furnace bottom, furnace body and furnace cover is about 1250kwh per ton of yellow phosphorus. For this reason, one of ...
