Description
Technical field
The utility model belongs to the coal gas treatment facility, and particularly a kind of gas furnace produces the energy-conserving and environment-protective treatment unit of water-gas.
Background technology
In the water-gas generators system of most of ceramic industries, the gas furnace outlet all has the dust separating facility of spray cooling, and nearly 600 ℃ of pyritous coal gas and dust not only contain more hazardous and noxious substances, also has a large amount of latent heat, directly contacting in the process of washing cooling with water, both wasted heat, hazardous and noxious substances is dissolved in the water, environment is caused very big pollution, and in the washing cooling, also consume a large amount of underground water, local water resources is constituted double threat.
Summary of the invention
Technical problem to be solved in the utility model provides the energy-conserving and environment-protective treatment unit that a kind of gas furnace produces water-gas, avoid coal gas of high temperature directly to contact with water with dust, reclaim the sensible heat in the coal gas of high temperature simultaneously, farthest utilize the limited energy, reach the purpose of energy-conserving and environment-protective.
The utility model gas furnace produces the energy-conserving and environment-protective treatment unit of water-gas, it is characterized in that comprising tornado dust collector, the heat pipe heat exchanging boiler, drum and static decoking device, the high-temperature water gas inlet duct connects tornado dust collector, tornado dust collector top center pipe coupling heat pipe heat exchanging upper boiler inlet, heat pipe heat exchanging boiler lower part outlet connects the static decoking device, the heat pipe evaporator bottom of described heat pipe heat exchanging boiler epimere connects water inlet pipe, water inlet pipe is connected with drum, heat pipe evaporator top hot water outlet connects drum by hot-water line, the heat pipe soft water heater bottom of heat pipe heat exchanging boiler hypomere connects cold soft water inlet pipe, the top connects another hot-water line, and this hot-water line the other end is connected to drum.
Tornado dust collector described in the utility model, heat pipe heat exchanging boiler and static decoking device are commercially available known products.The heat pipe heat exchanging boiler is two-stage heat-exchanger rig (structure formation is identical), epimere is heat pipe evaporator (first-class heat exchanger), because of top water gas temperature height, by the first step heat pipe evaporator water wherein is heated into steam, the saturation steam of generation uses by drum coal supply steam stove or other operation.Hypomere is heat pipe soft water heater (secondary heat exchanger), because of water-gas reduces through temperature after the heat exchange of the first step, make the water in the heat pipe soft water heater be heated into hot water, this part hot water produces efficient by the water inlet of drum as first step interchanger (heat pipe evaporator) thereby improve steam.Water-gas through second stage heat exchange after temperature reduce to about 130 ℃, enter through water seal again that electrostatic precipitator is removed dust particle and coal tar further purifies gas, reach requirement after, be delivered to the kiln utilization of burning through the high pressure gas gas blower.
Advantage of the present utility model:
The high-temperature water gas of having avoided carrying a large amount of dust secretly directly contacts with water, has promptly reduced the loss of heat, has improved the gas making efficiency of gas furnace, has stopped the pollution of venomous injurant confrontation environment again.Simultaneously, the energy has further been saved in the cancellation of cooling, bath water, has reduced consumption, has also conserved the water resources of local preciousness.After measured, be example with separate unit Φ 3000 gas furnaces, but about 1.5 tons of by-product 0.4MPa saturation steam per hour after the heat recuperation; The gas furnace gas making efficiency improves 10%, reduces coal consumption more than 5%.In addition, because of the cancellation of cooling, bath water, month water saving is more than 3000 tons, and nearly 60000KWH economizes on electricity.In addition,, the enthalpy of water-gas is got a promotion, greatly strengthened the utilization ratio of water-gas because the temperature of system outlet gas has increased 70 ℃ before transforming.
