Description
Technical field
The utility model relates to a kind of high-temperature flue gas flash cooler, particularly relates to a kind of high-temperature flue gas flash cooler of field of Environment Protection High-temp. kiln flue gas cool-down.
Background technology
Flue gas, furnace gas and coal gas equitemperature that industrial furnace produces are generally higher, are often in 150 ℃-600 ℃ scopes such as not, contain dust, SO in these gases more
2, the pollutant such as NOx, need purified treatment, but because the operating temperature of cleaning equipment is limited, therefore, the high-temperature flue gas processing of should lowering the temperature.
In environment-friendly engineering, the cooling method of high-temperature flue gas and equipment have various ways, common are waste heat boiler, water cooler, three kinds of modes of aerial cooler.Waste heat boiler is mainly used in the occasion that exhaust gas volumn is large, cigarette temperature is high, when exhaust gas volumn too hour uneconomical.Water cooler is the most traditional cooling system, exhaust gas volumn is large or littlely all can use, water at low temperature is entered, and high-temperature water goes out, and reduces flue-gas temperature by indirect heat exchange, cooling water is squeezed into cooling tower by circulating pump, after cooling, recycle, because needs configure cooling water preparation system and the circulatory system, invest larger, water pump operation energy consumption is large, should not use water-deficient area and severe cold area.Air is the most cheap low-temperature receiver, in engineering, often use air to make cooling medium, aerial cooler is common cooling system, the most traditional is natural wind cooler, it is that pipeline is constantly upper and lower bending in air, form larger heat exchange area, thereby utilize air natural heat radiation cooling when flow of flue gas.It is indirectly cooling that natural wind cooler belongs to, and cooling-down effect is affected by meteorological condition, because air velocity in atmosphere is little and variation often, heat transfer coefficient is low, and cooling-down effect is limited, and this equipment volume is larger in addition, steel consumption is many, particularly takes up an area greatly, and this is the shortcoming of traditional natural air cooler.
Summary of the invention
The utility model object is limitation and the shortcoming existing for above-mentioned cooling high-temperature fume equipment, particularly overcome traditional natural air cooler exist heat transfer effect poor, heat transfer area is large, steel consumption is many, take up an area the deficiencies such as large, a kind of high-temperature flue gas flash cooler is provided, can effectively solves traditional water cooler and the existing problem of natural wind cooler.
Technical solution of the present utility model is: a kind of high-temperature flue gas flash cooler is provided, comprises housing, air cooling pipe, air cooling pipe is arranged in housing, and vertical welding dividing plate on the side plate of the both sides of the positive apparent direction of housing forms S shape passage in housing; Dividing plate is porous plate, and hole count is identical with the quantity of air cooling pipe, and air cooling pipe, is welded on dividing plate through dividing plate by the hole on dividing plate.
Dividing plate described in the utility model is according to exhaust gas volumn and the requirement of flue gas temperature drop, and the quantity of dividing plate is adjustable, the also corresponding adjustment of S shape number of channels of formation.
Air cooling pipe described in the utility model is the hollow steel pipe that two ends are not sealed, and according to exhaust gas volumn and the requirement of flue gas temperature drop, its usage quantity is adjustable, and its horizontal layout can be determinant, quincunx, diamond type.
The utility model, according to the variation of air themperature or flue-gas temperature, is provided with shower water circulating cooling part, comprises header tank, water circulating pump, feed pipe, shower nozzle, and water leg is welded on the top board top of housing; Header tank is arranged on lower housing portion, and shower nozzle is arranged on housing top; Header tank is connected with shower nozzle with feed pipe by water circulating pump.
The course of work of the high-temperature flue gas flash cooler that the utility model provides is: high-temperature flue gas enters from cooler top, stream with air cooling pipe in mobile doing S shape, form strong heat convection in fume side, make flue-gas temperature fast reducing, obviously improve than natural wind cooler heat transfer effect, cooled flue gas is discharged from bottom; In the time that air themperature is lower (as winter), air enters from air cooling pipe bottom, in air cooling pipe, heating is risen, due to stack effect, air themperature is more and more higher, and speed is accelerated all the more, also formed strong heat convection in air side, after air heat, take away heat, discharge from air cooling pipe top, more more remarkable than natural wind cooler cooling effect.When flue-gas temperature or air themperature are when higher (as summer), can ON cycle water pump, cooling water, from top spray, collects in water leg, and water flows from top to bottom in air cooling pipe, forms evaporation and heat-exchange, and strengthening cooling-down effect, impels flue gas cooling fast.In high-temperature flue gas flash cooler bottom, header tank is set, for collecting recirculated cooling water.When the design of high-temperature flue gas flash cooler, can determine flue gas flow rate according to exhaust gas volumn, prevent dust stratification and pipe flushing.
The beneficial effects of the utility model are: overcome that the cooling-down effect that traditional natural air cooler exists is poor, steel consumption is many, take up an area the shortcomings such as large, is a kind of economic, efficient, reliable high-temperature flue gas flash cooler.
Accompanying drawing explanation
Fig. 1 is a kind of high-temperature flue gas flash cooler front view.
Fig. 2 is a kind of high-temperature flue gas flash cooler top view.
In figure: 1. housing; 2. air cooling pipe; 3. dividing plate; 4. water leg; 5. header tank; 6. circulating pump; 7. feed pipe; 8. shower nozzle.
The specific embodiment
A kind of high-temperature flue gas flash cooler the utility model proposes can be implemented in the following manner.
1. according to exhaust gas volumn and cooling requirement, select diameter, quantity and the arrangement of air cooling pipe 2, and make.
2. according to exhaust gas volumn and cooling requirement, select the quantity of dividing plate 3, i.e. flue gas S shape number of channels, and make dividing plate 3.
3. according to selected flue gas flow rate, and the quantity of air cooling pipe 2 and dividing plate 3, determine the length of housing 1.
4. housing 1 is resolved into some making, first do positive apparent direction two, dividing plate 3 is welded between two at a certain distance.
By air cooling pipe 2 through each dividing plate 3, and with its welding, top board, side plate and the base plate of the housing 1 of then burn-oning respectively.
