Abstract
An energy-saving environment protection air heater is applied to some places where use hot air to keep warm and dry spray painting (spray plastic). The package unit comprises a combustion heating furnace, a combustion exhaust-gas exchanger and a ventilation water-curtain purifier. An air heating-space is between the shell of the combustion heating furnace and the furnace; the combustion exhaust-gas exchanger is multi-tubular combustion exhaust-gas exchanger; the ventilation water-curtain purifier is adopted to purify the discharged exhaust gas. Coal is the fuel and the exhaust-gas emission is up to the national standard limit of smog release.
Description
Technical field
The utility model relates to the hot blast generation conveying device of a kind of energy savings energy, compliance with environmental protection requirements, is applied to places such as oven dry, baking vanish, heating.
Background technology
Be used at present to dry, the hot-blast stove kind in place such as baking vanish, heating is a lot, the fuel of use has coal, petroleum product, electric power etc.Have following defective in the prior art: there is the defective that the thermal efficiency is low, burning is incomplete, flue dust is big in the hot-blast stove that with coal is fuel; With petroleum product, electric power is that the hot-blast stove operating cost of fuel is too high.
Summary of the invention
At the defective that exists in the prior art, the utility model energy-conserving and environment-protective hot-blast stove is fuel with coal, burnt gas is carried out secondary heat exchange, discharging waste gas adopts ventilation cascade clarifier (to apply for a patent on January 20th, 2005, application number 200520080045.0) purify, make it that the thermal efficiency improves, burning fully, toxic emission is lower than national standard.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of energy-conserving and environment-protective hot-blast stove, form by combustion heating furnace, burnt gas heat exchanger, ventilation cascade clarifier, it is characterized in that: be the air heat space between the shell of combustion heating furnace and the combustion heating furnace burner hearth, its hot air outlet connects the heated air inlet of burnt gas heat exchanger; The flue gas outlet of combustion heating furnace connects burnt gas heat exchanger heated air inlet, and the heated air outlet of burnt gas heat exchanger connects ventilation cascade clarifier.The burnt gas heat exchanger is a shell and tube burnt gas heat exchanger.
The beneficial effects of the utility model are: we have manufactured experimently two bench teat experiment devices, be used in heating respectively and spray paint (plastic-blasting) oven dry, result of use is good, and outlet with the naked eye be can't see flue dust behind the Combustion of Hot Air Furnace waste gas purification, and its flue gas row meets national standard limit of smog release fully.
Description of drawings
Accompanying drawing is the organigram of energy-conserving and environment-protective hot-blast stove, among the figure: outlet, 2-ventilation cascade clarifier, 3-burnt gas heat exchanger, 4-burnt gas heat exchanger heat-exchanging tube, 5-hot-blast outlet, the import of 6-cold wind, 7-combustion heating furnace, 8-combustion heating furnace burner hearth, 9-combustion heating furnace burner hearth air inlet behind the 1-Combustion of Hot Air Furnace waste gas purification.
The specific embodiment
Embodiment 1 (being applicable to places such as heating or low temperature drying): fuel is in combustion heating furnace burner hearth (8) internal combustion of combustion heating furnace (7), air is entered by combustion heating furnace burner hearth air inlet (9), produce high-temp combustion waste gas, high-temp combustion waste gas enters the burnt gas heat exchanger heat-exchanging tube (4) of burnt gas heat exchanger (3) behind heating flame heating furnace burner hearth (8) outer wall air, temperature further reduces after the heat exchange, enter ventilation cascade clarifier (2) again, burnt gas is sloughed flue dust in ventilation cascade clarifier (2), pollutant such as sulfur dioxide is after outlet (1) discharging atmosphere behind the Combustion of Hot Air Furnace waste gas purification; Cold air is entered by cold wind import (6), enters burnt gas heat exchanger (3) post bake after combustion heating furnace (7) heating, sends hot blast through hot-blast outlet (5).
Embodiment 2 (being applicable to places such as baking vanish or hyperthermia drying): with hot-blast outlet (5) as the cold wind import, with cold wind import (6) as hot-blast outlet, other are identical with embodiment 1.But the hot blast that production temperature like this is higher.
We have manufactured experimently two bench teat experiment devices according to embodiment 1 and embodiment 2, be used in heating respectively and spray paint (plastic-blasting) oven dry, result of use is good, and outlet with the naked eye be can't see flue dust behind the Combustion of Hot Air Furnace waste gas purification, and its fume emission meets national standard limit of smog release fully.
Claims (2)
1, a kind of energy-conserving and environment-protective hot-blast stove, form by combustion heating furnace, burnt gas heat exchanger, ventilation cascade clarifier, it is characterized in that: be the air heat space between the shell of combustion heating furnace and the combustion heating furnace burner hearth, its hot air outlet connects the heated air inlet of burnt gas heat exchanger; The flue gas outlet of combustion heating furnace connects burnt gas heat exchanger heated air inlet, and the heated air outlet of burnt gas heat exchanger connects ventilation cascade clarifier.
2, energy-conserving and environment-protective hot-blast stove according to claim 1 is characterized in that: the burnt gas heat exchanger is a shell and tube burnt gas heat exchanger.
