Abstract

The utility model discloses a smelting furnace, this smelting furnace include the furnace body, the outer wall of furnace body is provided with a confined thermal -arrest space outward, thermal -arrest space intercommunication has the gas -supply pipe, the export of gas -supply pipe has connect a plurality of air nozzles, the air nozzle install in furnace body upper end and the opening in the furnace body. The utility model relates to a smelting furnace's beneficial effect: thereby having realized that the furnace body remains pick up the heat in guiding the furnace body through the waste heat with furnace body wall effluvium into through the pipeline, effectively having reduced energy consumption and manufacturing cost, should design simple structure, the practicality is strong.

Description

A kind of smelting furnace

Technical field

The utility model relates to a kind of metallurgical equipment, particularly relates to a kind of smelting furnace.

Background technology

Smelting furnace is important metallurgical equipment, and its heating-up temperature is conventionally higher, therefore in metallurgical operation process, can produce a large amount of waste heats, and current equipment is not recycled to its waste heat conventionally, has caused great energy waste.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of smelting furnace, and the waste heat of recoverable self is to reduce energy consumption.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of smelting furnace, comprises body of heater, and the outer wall of described body of heater is outside equipped with the thermal-arrest space of a sealing, and described thermal-arrest space is communicated with appendix, and the outlet of described appendix is connected to multiple air nozzles, and described air nozzle is arranged on body of heater upper end and opening in body of heater.

As preferably, on described appendix, air-introduced machine is installed.

As preferably, described air nozzle is 4-8.

As preferably, described air nozzle annular is distributed in body of heater upper end.

Compared with prior art, the beneficial effect of a kind of smelting furnace of the utility model: thus guide by the waste heat that furnace body wall is shed the recycling that has realized body of heater waste heat in body of heater into by pipeline, effectively reduce energy consumption and production cost, this project organization is simple, practical.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of smelting furnace of the utility model.

Wherein, Reference numeral: 1 is body of heater, 2 is thermal-arrest space, and 3 is appendix, and 4 is air nozzle, and 5 is air-introduced machine.
