Abstract
The utility model discloses a fuel gas horizontal zinc power furnace which utilizes fuels as coal gas, mixed gas or other gases to produce zinc powder. A cylinder heat exchanging chamber is positioned at front or one side of the firebox and is built by fire resistance bricks. An air inlet is positioned at bottom or lower side surface of the exchanging chamber, while the gas inlet is positioned in accordance with combustible gas temperature difference. When the combustible gas is not pre-warmed, the gas inlet is positioned at bottom or lower side surface of the heat exchanging chamber; when the combustible gas is warmed up, the gas inlet is directly positioned at upper of the heat exchanging chamber, thus the combustible gas directly enters the firebox to mix with the pre-warm air and then burn together.

The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of existing horizontal zinc powder stove, provide a kind of rational in infrastructure, the thermal efficiency is high, furnace temperature is stable, energy consumption is lower, the stove longevity is long, environmental pollution is less, output is high, the fine powder rate is high and can use coal gas or other combustion gas or the gaseous mixture a kind of zinc powder production metallurgy stove as fuel.
The utility model comprises evaporation tank, combustion chamber, melting tank, liquate pond, it is characterized in that being provided with tubular refractory brick at chamber front end or side builds the Heat Room that forms by laying bricks or stones, the import of air is located at the side of Heat Room bottom or bottom, and the fuel gas import is provided with the position difference according to the temperature difference of fuel gas.When fuel gas not during preheating, its import is located at the side of Heat Room bottom or bottom, and fuel gas flows to identical with air flow.The combustion chamber links to each other with Heat Room, evaporation tank is in the bottom, combustion chamber, melting tank and liquate pond are located at the side of evaporation tank, and the exhaust steam passage on combustion chamber, melting tank, top, liquate pond passes through Heat Room after being connected to Heat Room top again, and waste gas flows to opposite with the flow direction of air.The waste heat of burnt gas heats air and the fuel gas that enters the combustion chamber in Heat Room, the three carries out abundant heat exchange with indirect mode in Heat Room, make fuel gas and air after preheating, enter the combustion chamber internal combustion, made full use of waste gas residual heat, reduced energy consumption with higher temperature.When the fuel gas preheating time, its import is directly arranged in Heat Room top, fuel gas directly enter combustion chamber and preheating air mixed combustion.Evaporation tank is the horizontal rectangular structure, and the flame shield and the level that are provided with arcuate structure between evaporation tank and the combustion chamber are placed in evaporation tank top, and the arcuate structure plate that the heats that fuel gas produced such as coal gas are logical passes to the zinc liquid in the evaporation tank.
Also be provided with flame shield at melting tank and top, liquate pond, the heats that fuel gas produced such as coal gas adopt indirect mode to transmit heat to zinc ingot metal, zinc liquid by flame shield, make its melting and heat preservation, reduce and avoided the oxidation of zinc liquid, reduce the zinc unit consumption, and made full use of the waste heat of burnt gas.
Fuel gas and air are to utilize the chimney be located at behind the zinc powder stove or chimney to add pressure reduction that blower fan forms in stove fuel gas and the air air inlet from the diverse location of Heat Room is sucked in Heat Room and the combustion chamber.
Also be provided with the adjusting device of regulating exhaust gas flow in the exhaust steam passage.Can regulate the exhausted air quantity that is used to heat, melt zinc liquid, zinc ingot metal arbitrarily, guarantee that melting tank and liquate pond temperature keep optimal parameter at any time.
Flame shield can be SiC plate or other material plate.
The structure of evaporation tank part is the horizontal rectangular structure.
The zinc powder fine powder rate height that the horizontal zinc powder furnace structure of this gas type is reasonable, the thermal efficiency is high, the stove daily output is big, energy consumption is low, the stove longevity is long, labour intensity is little, environmental pollution is little, produced, active big.
