Abstract
The invention discloses a pretreatment device of a coal-charging flue gas from a side-loaded tamping coke oven. The pretreatment device is characterized in that the upper end of a bracket is provided with a ring beam; the ring beam is provided with uprights and a cabin body located between the uprights; the upper ends of the uprights and the cabin body are provided with upper cover plates; the outer side wall of the cabin body is provided with an air intake pipe and an air outtake pipe which are communicated with the inside of the cabin body; an ash bucket communicated with the inside of the cabin body is arranged below the ring beam on the bracket; the lower end of the ash bucket is provided with ash discharging port; the inner wall of the cabin is provided with an upper inner clapboard and a lower inner clapboard located below the upper inner clapboard; and the lower part of the cabin body is internally provided with a downwardly inclined left inner slide carriage, a middle inner slide carriage and a right inner slide carriage. In the invention, the inner clapboards and the inner slide carriages are arranged in the cabin body, so that the flue gas and dried dust flow in a channel formed by the inner clapboards and the inner slide carriages and stirred and mixed, flocculent floater and sticky coal tar smoke in the flue gas are adhered on the dried dust so as to form larger and heavier particles which crash with the inner wall plate of the cabin body in movement so as to reduce a speed and then lead the particles to fall into the ash bucket, thereby achieving good smoke filtrating effect.
Description
Technical field
The invention belongs to and belong to coke oven coal-charging smoke pretreatment unit technical field, be specifically related to kind of a pretreatment device of coal-charging flue gas from side-loaded tamping coke.
Background technology
Coke oven production is in the process of coalingging to coking chamber, diffuse the hole and a large amount of poisonous and harmful flue dust are distributed in pusher side fire door top to air from furnace roof, wherein contain higher tar ingredients and moisture, belong to the viscosity composition, viscosity composition in the coal-charging smoke mainly can be divided into two classes, the first kind is to have certain viscosity and humidity, a cotton-shaped floating matter that granularity is larger, and Equations of The Second Kind is for take tar gas as main, sticking fine particle.Mainly contain following several for above-mentioned smoke catching and purifying method at present:
A kind of is to adopt burning water-added method of washing, and the main drawback of this method is that energy consumption is high, water loss is high, easily causes the secondary pollution of water; Another kind is to adopt the flue gas adsorption and purification technology, and the shortcoming of this method is that required equipment is more, invests higher; Also having a kind of is that flue gas preconditioning technique and pre-spraying filtering technology combine, the flue gas preconditioning technique is to spray dry and noncohesive dust at the smoke inlet place when flue gas enters the processing storehouse, the two uniform stirring in processing the storehouse mixes, dried dust is bonded on cotton-shaped floating matter and the part coke tar particles, form large heavier particle, flue dust in processing the storehouse with bucket in slide carriage collision change flow direction, Speed Reduction, the macrobead that underspeeds in action of gravitation drops ash silo, thereby cotton-shaped floating matter and most of viscosity tar flue dust in the flue dust are separated.
Pre-spraying filtering technology is that coal-charging smoke directly enters sack cleaner, although the pre-sprayed coating that dried dust forms can prevent the generation of " paste cloth bag " phenomenon, but a large amount of cotton-shaped floating matters and viscosity tar cigarette can be piled up and cover on the cloth bag, make cloth bag just lose in a short period of time strainability, pressure drag increases, need high-frequency blowback or increase blower fan power to solve this problem, both increased and dropped into and power consumption, reduced again cloth bag work-ing life, and cotton-shaped floating matter and the also easily accumulation bridging between cloth bag of tar cigarette, affect the flue gas circulation and unload carrying out smoothly of ash.
Summary of the invention
Technical problem to be solved by this invention is to overcome the coaling shortcoming and defect of flue gas of the pre-spraying filtering technical finesse of traditional direct usefulness, and a kind of reasonable in design, simple in structure, pretreatment device of coal-charging flue gas from side-loaded tamping coke that treatment effect is good is provided.
Solving the problems of the technologies described above the technical scheme that adopts is: be provided with collar tie beam in the support upper end, be provided with column and the warehouse between column on the collar tie beam, column and warehouse upper end are provided with upper cover plate, be provided with on the warehouse outer side wall with warehouse in the blast pipe and the air outlet tube that link, on the support collar tie beam below be provided with warehouse in the ash bucket that links, the ash bucket lower end is provided with ash discharging hole, be provided with internal partition on the warehouse inwall and be positioned at the lower internal partition of internal partition below, in the warehouse bottom be provided with downward-sloping left inside slide carriage, in slide carriage, right inside slide carriage.
Left inside slide carriage of the present invention is that the angle β with the vertical direction negative sense is 20 °～30 ° straight plate.Slide carriage is that the angle δ with the vertical direction negative sense is 20 °～30 ° straight plate in of the present invention.Right inside slide carriage of the present invention is that the angle γ with the vertical direction negative sense is 20 °～30 ° straight plate.
The angle β of left inside slide carriage of the present invention and vertical direction negative sense, in the angle γ of slide carriage and the angle δ of vertical direction negative sense, right inside slide carriage and vertical direction negative sense identical.
Upper internal partition of the present invention is that the bending angle α with the vertical direction forward is 40 °～50 ° flap.
Lower internal partition of the present invention is the vertical plate vertical with horizontal plane.
Blast pipe of the present invention is 1: 1 with the pipeline actual internal area ratio of air outlet tube.
Ash bucket of the present invention is that upper bottom surface is greater than the terrace with edge shape of bottom surface.
Ash bucket the best of the present invention be upper bottom surface greater than the positive truncated rectangular pyramids shape of bottom surface, tapering is 21 °～30 °.
The present invention adopts internal partition and interior slide carriage is set in warehouse, internal partition warehouse play the flue gas flow admittance to effect, entering flows in the passage that flue gas in the warehouse and dried dust form by internal partition and interior slide carriage in warehouse also fully mixes, cotton-shaped floating matter in the flue gas and most of viscosity tar cigarette stick to and form on the dried dust on the large heavier particle, thereby these particles at the volley with warehouse in wallboard collision underspeed, under action of gravitation, settle down, fall into ash bucket.Reasonable in design, simple in structure, filtrating smoke dust high treating effect that the present invention has can be promoted the use of in coke production.
