Description
Technical field
The utility model belongs to fume afterheat and utilizes technical field, refers in particular to a kind of to grain heat-drying pulverized coal hot air furnace
The improvement of deduster, to improve its utilization rate of waste heat.
Background technology
In China grain heat-drying field, mostly using coal-fired hot-blast stove as thermal source, in production, the exhaust smoke level of hot-blast stove is
It is very big.Present production technology exhaust gas temperature is mostly 120~140 DEG C or so, the so high flue gas removing dust desulfurization of temperature
Air is discharged into after technique, produces very big thermal loss.Asked due to cryogenic condensation corrosion and resulting stickiness black dirt be present
Topic, existing heat exchanger will avoid the exhaust gas temperature of heat exchanger exit too low in design, to ensure the use longevity of heat exchanger
Life and safety.Therefore, 120~140 DEG C or so of the smoke evacuation flue dust containing amount of heat air is discharged into from flue gas and not by
Make full use of, cause Thermal Efficiency of Hot Blast Stoves to decline, coal consumption rises, and aggravates environmental pollution.Used with drying the drying of 500 tons of wet grain day
Exemplified by hot-blast stove, exhaust gas volumn is about vertical m/h of 36000-42000, and flow is the flue gas come out from hot-blast stove back-end surfaces
After heat exchanger exchanges heat, into deduster dedusting, it is pressurized by air-introduced machine, desulfurization process is carried out into desulfuration absorbing tower desulfurization,
Most it is discharged into air through chimney afterwards.This partial heat is all disposed in air at present, is caused larger waste, be result in energy stream
Fuel availability of becoming estranged reduces, and had not only polluted environment but also had added production cost.
The content of the invention
The utility model provides a kind of deduster that can improve utilization rate of waste heat, to solve deduster utilization rate of waste heat
The problem of low.
The utility model adopts the technical scheme that：Body of deduster is fixedly connected with support, and dustless exhanst gas outlet is located at
The top of body of deduster, flue dust import are located at body of deduster side, and replenishing water tank of water is fixedly connected with support, body of deduster
Bottom have decontamination mouth, shaped Venturi dedusting pipe is located inside body of deduster, and dash pipe both ends are fixed with body of deduster side wall
Connection and both ends are located at the outside of side wall, and the external stability in the body of deduster two side with dash pipe diameter parallel is connected
Wall outside sandwich, there is cold air cover in one end of dash pipe and wall outside sandwich, the cold air cover is fixed with body of deduster outer wall to be connected
Connect, have heating air trapping cover in cold air cover offside, the heating air trapping cover is fixedly connected with body of deduster outer wall, should
Cold air cover is covered with inlet of cold air by dash pipe and wall outside sandwich with heating air trapping cover UNICOM, the cold air, should add
Hot-air is collected and is covered with heated air outlet；
Each dash pipe is parallel to each other.
The cold air cover is trapezoidal.
The utility model has the advantages that：Structure is novel, easy to make, in existing hot-blast stove deduster, by original flat board
Shape water fender is replaced by cast dash pipe, and this is external by the stretching of pipe both ends termination, and in tube head outlet, both ends of the surface make one respectively
Whole end face side including leaning out the tube head of deduster outer face is included in by individual trapezoidal cold air cover, the cold air cover
It is interior；In addition to using the waste heat in deduster, another two outer surface of deduster, still there is certain temperature, by increasing an interlayer,
And with cold air cover UNICOM, form a cavity, cold air is after dash pipe and interlayer are heated from as the another of outlet
End discharge, the purpose for absorbing waste heat is realized, meanwhile, the intake air temperature into coal pulverizer or air blower is improved, is advantageous to equipment
Operation, improve operating efficiency, save the energy.
