Description
Technical field
The present invention relates to a kind of hot-blast stove.
Background technology
Existing hot-blast stove mainly contains four kinds of fundamental types:
1, single flow metal fever wind furnace, main heat exchange body are 3 barrel structures, and secondary heat exchange body is the monotubular structure; Adopt the single process heat exchange principle, the problem of existence: volume is bigger, and chimney is installed inconvenience on furnace roof, and exhaust gas temperature is higher, and is energy-conservation still potential.
2, jet flow hot-blast stove, the heat exchange body is made of 5～6 cylinders, adopts air-flow to spray heat exchange principle, and subject matter is complex structure, and cost is higher, and power consumption is bigger, and service life is not as good as the single flow hot-blast stove.
3, sleeve air multi-return-stroke type hot-blast stove is formed by 4～8 jacket casing dresses, and the flow path resistance coefficient is bigger, and reducing power consumption has certain degree of difficulty, and the inner barrel ratio is easier to be damaged.
4, two adverse current durable highly efficient hot-blast stoves adopt two countercurrent heat exchange principles, and the same difficulty with other cartridge type hot-blast stoves develops to medium-and-large-sized direction, and maximization can bring the difficulty in the transportation.
Do not belong to the vertical pipe type and the shell and tube hot-blast stove of cartridge type hot-blast stove in addition in addition, its advantage is easy maximization, and the problem of existence is that heat transfer coefficient is little, and it is many to consume material, and cost is higher, and service life is on the low side, and deashing has certain degree of difficulty.
The shortcoming that existing hot-blast stove exists: volume is big, and it is many to consume material, and the inclined to one side people of power consumption in energy-efficient, can not take into account cost and service life, and durability is relatively poor.
Summary of the invention
In order to overcome the deficiency that can not take into account efficient energy-saving, low cost and long life of existing hot-blast stove, the invention provides a kind of efficient energy-saving, material economy, low cost is than the horizontal former pressure-bearing type heat exchanger of long life.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of horizontal side plate vertical type hot-blast furnace, comprise the heat exchange body, the bottom of described heat exchange body is a body of heater, the bottom of described body of heater is a fire grate, the top of described fire grate is burner hearth and high temperature plume radiation area, described heat exchange body is made up of cabinet shape wall body, the outside of described cabinet shape wall body is the wall type air channel, the outer wall of described heat exchange body is installed the ventilation former, it between the described ventilation former width of cloth formula air channel, the top width in described width of cloth formula air channel is bigger than bottom width, described width of cloth formula air channel and wall type air channel are combined into compound air duct, the outside in described wall type air channel is the wall flue, and the outside of described wall flue is a cold air duct, and described compound air duct is separated into plural workspace, adjacent workspace, front and back is communicated with by the transition air channel at heat exchange body top, described cold air duct is communicated with the bottom of the compound air duct of preceding workspace, and the bottom of the compound air duct of workspace, described back and the hot blast chamber of confluxing is communicated with, and the described hot blast chamber of confluxing is communicated with hot-blast outlet; Described high temperature plume radiation area is communicated with the mouth that advances of described wall flue, and the outlet flue of described wall flue is communicated with described side exhaust opening.
Further, described wall flue is symmetricly set on the both sides of cabinet shape wall body, and the postmedian of described wall flue is separated into upper flue and lower flue, described upper flue with advance mouth and be communicated with, described lower flue is communicated with outlet flue, the front end of described wall flue is provided with the deashing window.
Further again, the top of described heat exchange body is provided with overhead guard, is the transition air channel between described heat exchange body and the overhead guard.
Further, the top of described overhead guard is provided with air intake cover, and it is air inlet that described air intake cover top framework and front end are left several apertures, and described air inlet is communicated with described cold air duct.
Technical conceive of the present invention is: adopt width of cloth formula air channel can improve the utilization rate of heat exchange body with interior heat transfer space, and can shorten main heat exchange flow process and the volume that dwindles heat exchanger and hot-blast stove, the raising air velocity that shortens to of heat exchange process has been created condition, adopt to become wind speed (also exist low-angle unsteady flow to) composite channel, can realize all reinforcement heat exchange effects of relative high flow rate of high-temperature high-flow rate, the low flow velocity peace of low temperature, heat transfer area can be dwindled, and the temperature of heat exchange height temperature workspace can be reduced.Adopt the result who becomes wind speed width of cloth formula air channel to be: heat exchanger volume is little, material economy, and cost reduces, and improve service life, and can reduce power consumption.
Beneficial effect of the present invention mainly shows: 1, heat utilization efficiency improves, and power consumption reduces; 2, material economy, manufacturing cost reduces; 3, improve service life; 4, soot emissions composite environmental-friendly requirement; 5, equipment can be realized maximizing easily.
