Abstract
The utility model discloses a blast stove which consists of two parts, namely a combustion chamber and a heat exchange component; wind shields are arranged in the heat exchange component; and the bottom of the heat exchange component is provided with a protective layer formed by pouring fireproofing material. As the protective layer is formed by pouring the fireproofing material at the bottom of the heat exchange component, a heat exchanger can not be directly contacted with a flame, a carbon steel at the bottom of the heat exchanger can not be bent and deformed at a temperature for a long period of time, and the service life of the blast stove is prolonged by more than twice. As a plurality of wind shields are arranged in the heat exchange component, the heat exchange area of the heat exchange component is enlarged and the time of cold air in the heat exchanger is prolonged; therefore, the air is heated more sufficiently and the thermal efficiency of the blast stove is greatly improved.
Description
Technical field
The utility model relates to a kind of hot-blast stove, relates in particular to a kind of long service life, hot-blast stove that the thermal efficiency is high.
Prior art
Existing hot-blast stove mainly is to adopt in drum type brake body of heater bottom the combustion chamber is set, the vertical heat exchanger of installing in the upper chamber, and top connects air outlet and forms, combustion chambers burn fuel heating heat exchanger, wind is exported from air outlet.Because heat exchanger all directly contacts with flame, bottom the heat exchanger carbon steel under high temperature for a long time, easy deformation, bending, the service life of heat-exchanging component is all very short.Moreover owing to be straight barrel type in the furnace chamber, directly go out from air outlet from the gas that air inlet is come in, the limited time of gas in furnace chamber can not be heated fully, and exhaust gas temperature height, thermal loss are very big, the thermal efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model provides the hot-blast stove that a kind of life-span is long, the thermal efficiency is high.
In order to solve the problems of the technologies described above; the technical scheme that the utility model adopted is: utilize the bottom of refractory material casting at the hot-blast stove heat-exchanging component; form protective layer; protective layer directly contacts with flame; make not flexible under long-time high temperature, the distortion of heat exchanger bottom carbon steel; be protected, thereby prolonged service life of hot-blast stove.Heat-exchanging component is by heat exchanger, floral disc, deep bead constitute up and down.The two ends of heat exchanger are welded on up and down on the floral disc, be provided with deep bead in the heat exchanger assembly, deep bead is installed in up and down between the floral disc, utilize deep bead to increase the heat exchange area of heat-exchanging component, can increase a plurality of deep beads as requested, the flow process of cold air in heat exchanger prolonged, fully heated, thereby improved the thermal efficiency.
Be provided with refractory brickwork around the combustion chamber, the hot-blast stove housing is effectively protected, housing is provided with heat-insulation layer outside being provided with air inlet, air outlet, feeding port, cleaning door, chimney seat, housing.
The invention effect
The beneficial effects of the utility model are: because the protective layer that has refractory material casting to form in the heat-exchanging component bottom; heat exchanger can directly not contact with flame; thereby heat exchanger bottom carbon steel can flexural deformation under long-time high temperature yet, and prolong more than 2 times the service life of hot-blast stove.Because be provided with a plurality of deep beads in heat-exchanging component, the heat exchange area of heat-exchanging component strengthens, the time lengthening of cold air in heat exchanger, and gas obtains more abundant heating, and the thermal efficiency of hot-blast stove is greatly improved.
