Description
Technical field
The present invention relates to a kind of flue gas processing device, particularly the multistage flue gas processing device of a kind of combustion furnace of energy-conserving and environment-protective.
Background technology
At present, the flue gas that state's internal fired furnace produces be all in undressed situation directly discharged to atmosphere, a large amount of fume emissions has caused atmosphere pollution, greenhouse effects, destroy the ecological balance.
The present invention proposes a kind of multistage flue gas processing device of combustion furnace of energy-conserving and environment-protective.
Summary of the invention
The present invention has overcome existing deficiency in above-mentioned prior art, and a kind of multistage flue gas processing device of combustion furnace of energy-conserving and environment-protective is provided.
Technical scheme of the present invention is achieved in that
The multistage flue gas processing device of a kind of combustion furnace is provided with secondary preheating water tank above the exhanst gas outlet of combustion furnace, between exhanst gas outlet and secondary preheating water tank, leaves space, is provided with the A of dust setting chamber and the B of dust setting chamber in the both sides in space; Described space is all connected with the A of dust setting chamber and the B of dust setting chamber, and the described A of dust setting chamber and the B of dust setting chamber are communicated with respectively one-level preheating connector, one-level preheating connector connects air-introduced machine by being communicated with air-introduced machine connector, and air-introduced machine is connected with the dust water treatment box that is provided with chimney.Combustion furnace flue gas is introduced into one-level preheating connector, air-introduced machine connector, air-introduced machine successively by air-introduced machine; The high-temperature flue gas heating that secondary preheating water tank has utilized combustion furnace directly to produce, one-level preheating water tank has utilized the temperature of high-temperature flue gas in the one-level preheating connector of flowing through to heat, and heat energy is utilized effectively, and has saved fuel.
As preferably, described one-level preheating connector is surrounded by one-level preheating water tank outward, and described one-level preheating water tank is connected with secondary preheating water tank by water pipe, water body in cross current combustion furnace.
As preferably, the height in described space is 20～30cm.For the revolution of high-temperature flue gas provides space.
Adopt design starting point of the present invention, theory and the beneficial effect of technique scheme to be:
The invention provides a kind of multistage flue gas processing device of combustion furnace of energy-conserving and environment-protective, the flue gas that combustion furnace produces enters space through exhanst gas outlet, high-temperature flue gas forms High Rotation Speed air-flow in secondary preheating water tank bottom, for secondary, preheating water tank provides heat, some particles in flue gas have fallen into the A of dust setting chamber and the B of dust setting chamber of both sides, space, flue gas enters in one-level preheating connector, the one-level preheating water tank who is wrapped in outside one-level preheating connector utilizes the temperature of high-temperature flue gas in the one-level preheating connector of flowing through to heat, heat energy is utilized effectively, high-temperature flue gas has become low-temperature flue gas, flue gas enters air-introduced machine and dust water treatment box successively subsequently, dust granules in flue gas falls into after processed in dust water treatment box and becomes innocuous gas, and then enter atmosphere, very environmental protection.
