Abstract

The box heater of silicon tetrachloride conducting furnace, relates to silicon tetrachloride production technical field, and integrated many row S shape pipelines in an incubator, order serial connection mutually between each row S shape pipeline, arranges a pipe head and a pipe outlet outside incubator.Be serially connected in by each box heater between each group of heater, the air in case serves as thermal insulation layer, high insulating effect, can greatly reduce thermal loss, improves the thermal efficiency, and, can make by disposable integral, save duration and expense.

Description

The box heater of silicon tetrachloride conducting furnace

Technical field

The utility model relates to the production technology of silicon tetrachloride production technical field, particularly its heating element heater.

Background technology

Need to heat raw material in silicon tetrachloride is produced, and the temperature needed is higher, traditional mode of heating adopts all-radiant furnace, but all-radiant furnace is heavy, and cost is high, and parts are many, complex structure, and heat utilization efficiency is low.Used again the heat supply of cast type heater afterwards instead, but heater is evenly arranged power, the spot temperature at heater outlet temperature place can be made so high, the most impaired.

If adopt heating element heater to be cast in intrametallic mode, allow metal casting entirety generate heat, heat transfer is carried out to the medium of metal casting inner chamber, then heat utilization efficiency can be made to improve.

But because production technology needs raw material to need the process heated up gradually through multistage, be serially connected in by the one-pipe of insulation between each group of heater, due to this structure, the raw material after intensification to have scattered and disappeared partial heat in one-pipe link, and heat energy loss is large in the past.

Utility model content

The utility model object proposes a kind of box heater that effectively can reduce the silicon tetrachloride conducting furnace of thermal losses.

The utility model is integrated many row S shape pipelines in an incubator, and order serial connection mutually between each row S shape pipeline, arranges a pipe head and a pipe outlet outside incubator.

Be serially connected in by each box heater between each group of heater, the air in case serves as thermal insulation layer, high insulating effect, can greatly reduce thermal loss, improves the thermal efficiency, and the utility model can make by disposable integral, saves duration and expense.The utility model also can be applicable in the electric heater industries such as oil, petrochemical industry, natural gas, chemical industry, electric power, metallurgy, machinery, medicine, food and civilian fire line.
