Description
Technical field
The utility model relates to a kind of energy-saving environmental protection device, particularly a kind of sintering furnace waste gas afterheat recovery unit, belongs to environmental protection and energy saving technical field.
Background technology
In the industrial circle of China, steel industry is the industry of typical highly energy-consuming, high pollution, and China's steel and iron industry energy consumption level is higher than industrially developed country by about 10%, and the secondary energy sources such as waste gas residual heat, overbottom pressure, coal gas account for 15% of enterprise's energy total amount.Highly energy-consuming brings very large economic pressures to the sector.Too much energy resource consumption, not merely have impact on the output of enterprise, and to a great extent, limits the development of steel industry.Consuming the comparatively serious steel industry of the energy, energy-conservation recovery, consumption reduction reduce discharging, and become paying close attention to and studying a question of the sector.Sintering is the operation that in steel industry production process, blast furnace mineral aggregate enters stove, and according to the study, sintering circuit can account for about 12% of iron and steel enterprise's total energy consumption for the waste heat utilized, wherein the waste heat of sintering deposit accounts for 8%, and sintered discharge gas waste heat accounts for 4%, obviously, reclaim and utilize these heats, particularly important.
Sintered discharge gas is owing to being the waste gas produced in compound sinter molding process, so dustiness is comparatively large, along with the change of technological operation situation, EGT is generally at about 120 ~ 180 DEG C.In prior art and technique, after usually making the waste gas carrying certain heat carry out dedusting in electric dust collector, by air exhauster, chimney, directly enter air, the heat of waste gas does not reclaim, and is just discharged in air, causes the waste of secondary energy sources.
Summary of the invention
The purpose of this utility model is to overcome that existing equipment easily blocks, the shortcoming of inefficiency, a kind of sintering furnace waste gas afterheat recovery unit is provided, solves the energy waste of middle-low temperature heat formation and the cleaning difficult problem of serious thermal pollution and existing equipment that existing equipment is difficult to effectively recovery.
The technical scheme that the invention for solving the technical problem adopts:
A kind of sintering furnace waste gas afterheat recovery unit, comprise housing, heat exchange core body, blower fan, water receiving pipe, connection airduct and electric cabinet, it is characterized in that: in housing, establish two frame rooms, left and right, heat exchange core body is equipped with in frame room, two, left and right, be provided with water receiving pipe in housing upper position, be provided with connection airduct on the right side of housing, blower fan is connected with housing frame room by connecting airduct, be provided with Stainless steel mesh screen pack at air inlet end, on the left of housing, be provided with exhaust vent.
Described heat exchange core body comprises some blocks of arc plates, and arc plate forms heat exchange core body entirety by being connected and fixed with collection plate, tube sheet, fixed head and upper cover plate, and heat exchange core body is provided with water inlet and delivery port.
Described arc plate comprises two pieces of stainless steel wave cards, and two pieces of corrugated platings form arc plate by welding, be provided with water stream channel, between arc plate, form gas channel in arc plate.
Described arc plate outer surface is provided with corrosion resistant coating.
Described blower fan is provided with electric cabinet, and electric cabinet is connected with air inlet end and exhaust vent temperature detector by wire.
The following describes its course of work:
The fan inlet end of waste-heat recovery device is provided with Stainless steel mesh screen pack, first hot waste gas is tentatively filtered; High-temperature hot exhausting section adopts corrosion resistant coating arc plate structure, and plate internal channel walks the high temperature circulation water of 60-80 DEG C, for making the thermal source of BrLi chiller; Waste gas after cooling is again through sub-cooled section, and plate internal channel directly walks the river of 20-25 DEG C, makes full use of existing low-temperature receiver; Adopt novel anticorrosion arc plate in high and low temperature section, whole heat exchange core body can be extracted out from top, while effectively improving heat transfer efficiency, also facilitates follow-up replacing cleaning.
Novel anticorrosion arc plate structure main advantage adopts stainless steel ripple plate sheet welding to become a passage, because sheet material is thinner, simultaneously on plate with the ripple that punching press is good, therefore heat-transfer effect is higher; Between each passage, spacing can tune up, thus the resistance of waste gas circulation is little, weares and teares little; Stainless steel corrugated sheet appearance is provided with epoxy resin corrosion resistant coating, and have comparatively strong corrosion resistant ability, service life of equipment is longer.
The beneficial effects of the utility model:
(1) reclaimed the waste gas residual heat of sintering furnace, utilize this residual heat high-temperature section can heat hot water for BrLi chiller, can bromizate lithium refrigeration unit when making the chilled water of 15-20 DEG C, Energy Efficiency Ratio reaches about 0.7; Low-temperature zone heat adopts river directly to cool, and saves fuel cost, reduces the operating cost of factory.
(2) heat exchange unit adopts novel anticorrosion arc plate structure, improves heat transfer effect, designs sheet surface simultaneously and coats corrosion resistant coating, extend the service life of heat exchanger.
(3) whole heat exchange core body makes removable structure, facilitates later cleaning and maintenance.
