Metal hot blast heater

Abstract

The invention discloses a metal hot blast heater, which is characterized by comprising a hot air pipe, an inner furnace pipe, a sieve hole jet-flow cylinder, an air duct, a centrifugal fan, a smoke pipe, a boiler smoke guide machine, a chimney, a dust remover, a porous partition board, a smoke spraying nut, a shell-and-tube heat exchanger, an air inlet pipe, perforated furnace feet, an inner-layer high-temperature smoke cylinder, an outer-layer high-temperature smoke cylinder, a hot air neutral layer, a spiral heat conduction sheet, a heat conduction board, an outer cylinder, a heat insulating layer, a shell, a sieve hole jet-flow cylinder connection board, an inner furnace pipe connection board, a hot air jet-flow pipe connection board, a supporting pipe, a motor and a furnace door. The metal hot blast heater provided by the invention aims to overcome the defects in the traditional hot blast heater of poor heating effect and poor heat transfer effect. According to the improvement, the invention provides the metal hot blast heater, so that the purpose of good heat conduction effect is realized by enlarging the contact area with air. Furthermore, the effect of the environmental friendless can be realized through inlet-outlet treatment of discharged smoke.

Description

technical field [0001] The invention relates to an energy-saving stove, in particular to a metal hot blast stove. Background technique [0002] Hot blast stoves are widely used in many fields. Traditional hot blast stoves generally include a furnace, a furnace body and a furnace seat. The furnace body is surrounded by air interlayers, and air inlets and air outlets are provided in the air interlayers. However, the traditional hot blast stoves After heating the air, the hot smoke from the hot blast stove is directly discharged into the atmosphere through the chimney, without treatment and absorption, which affects the environment. The discharged smoke takes away a lot of heat, the heating effect is poor, the heat transfer effect is poor, and a lot of energy is wasted. In addition, this traditional hot blast stove achieves the purpose of heating the cold air because the high temperature generated by the combustion of fuel in the furnace conducts heat to the cold air in the ai...
