Abstract
The utility model relates to a quaternary body hot-blast furnace. The hot-blast furnace comprises a circulating air inlet, a circulating air outlet, a fresh air adding opening, an exhaust gas opening, a heat exchanger, a filter, a burner, a smoke discharge chimney and a circulating air fan, wherein the circulating air inlet is arranged on the lower portion of the heat-blast furnace, the exhaust gas opening is arranged on the upper portion of the hot-blast furnace, the burner is arranged below the exhaust gas opening, the heat exchanger is arranged on the middle portion of the hot-blast furnace, and the filter is arranged on the back portion of the heat exchanger. The quaternary body hot-blast furnace is clean and pollution-free. Since the hot-blast furnace can combust sufficiently, exhaust gas emission is lower than state environmental protection requirements. By means of an indirect exhaust heat exchanging structure, the heated circulating air does not contact with the exhaust gas and remains clean, and the burner automatically shuts off or reduces fire when temperature in the hot-blast furnace reaches a set temperature. When the temperature is lower than the set temperature, the hot-blast furnace automatically starts up, and temperature of output air can be precisely controlled.
Description
Technical field
The utility model relates to a kind of oven dry heating and uses hot-blast stove, relates in particular to a kind of quaternary-body hot blast stove.
Background technology
Therefore at present, the temperature during the waste gas combustion furnace fume emission need to be controlled at below 250 ℃, because flue-gas temperature is higher in the incinerator, need to carry out efficient and rational heat exchange, and heat tends in vain waste in heat transfer process.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, heat exchange efficiency is high, the quaternary-body hot blast stove of good filtration effect, energy-conserving and environment-protective.
The technical solution of the utility model is: be provided with circulated air import, circulated air outlet in the described hot-blast stove, mend fresh wind port, exhaust outlet, heat exchanger, filter, combustor, chimney and circulating fan, described circulated air import is arranged on the hot-blast stove bottom, described exhaust outlet is arranged on hot-blast stove top, described combustor is arranged on the exhaust outlet below, described heat exchanger is arranged on the hot-blast stove middle part, and described filter is arranged on the heat exchanger rear portion.
Connected electromagnetic valve and PLC intelligent controller on the described combustor.
Described hot-blast stove is provided with access door, is filled with heat-preservation cotton in the hot-blast stove housing.
The utility model adopts clad steel version, liner galvanized steel plain sheet or corrosion resistant plate, the zinc-plated corrugated plating of outer subsides or colored steel, heat-preservation cotton is tamped in the centre, and the side is provided with access door, and this equipment cleaning is pollution-free, hot-blast stove is owing to fully burning, and fume emission is lower than national requirements for environmental protection; Indirect type flue gas heat exchange structure makes heated circulated air in flue gas contact, keeps clean, and combustor turn-offs voluntarily or reduces firepower when reaching design temperature in the hot-blast stove; When being lower than design temperature, start voluntarily, the output air temperature can accurately be controlled.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is to mend fresh wind port among the figure, the 2nd, and exhaust outlet, the 3rd, heat-preservation cotton, the 4th, heat exchanger, the 5th, access door, the 6th, filter, the 7th, circulated air outlet, the 8th, circulating fan, the 9th, chimney, the 10th, combustor, the 11st, circulated air import.
The specific embodiment
Quaternary-body hot blast stove, be provided with circulated air import 11 in the described hot-blast stove, circulated air outlet 7, mend fresh wind port 1, exhaust outlet 2, heat exchanger 4, filter 6, combustor 10, chimney 9 and circulating fan 8, described circulated air import 11 is arranged on the hot-blast stove bottom, described exhaust outlet 2 is arranged on hot-blast stove top, described combustor 10 is arranged on exhaust outlet 2 belows, described heat exchanger 4 is arranged on the hot-blast stove middle part, described filter 6 is arranged on the heat exchanger rear portion, connected electromagnetic valve and PLC intelligent controller on the described combustor 10, described hot-blast stove is provided with access door 5, be filled with heat-preservation cotton 3 in the hot-blast stove housing, mix wind and carry out flue gas heat exchange through circulated air import 11 and heat exchanger 4, then the effect by circulating fan 8 enters baking oven through the filtration of filter 6 again by exhaust outlet 2, temperature passes to after the workpiece, enter heat exchanger 4 by circulated air import 11 again, circulate with this; Combustor 10 provides thermal source for mixed heat, and will be burnt fully, be decomposed by the organic exhaust gas of exhaust outlet 2 accesses, makes its qualified discharge, when the hot-blast stove internal temperature is higher, opens and mends fresh wind port 1, reduces temperature in the hot-blast stove.
