Abstract
The invention belongs to the technical field of boiler parts, and specifically relates to an irregular ash falling device. The device comprises a front ash bucket, a rear ash bucket, an access door and a rotary ash discharging valve; the front ash bucket is connected with a smoke channel at the tail part of a boiler; the rear ash bucket which is communicated with the front ash bucket is connected with a smoke channel at an outlet of the boiler; a trough type separator is obliquely arranged at a part in which the front ash bucket is connected with the rear ash bucket. With the adoption of the device, lots of ash in the smoke can be effectively separated, thus the phenomenon of ash-doped smoke returning of the ash buckets can be avoided; the effect of removing ash is obvious, the smoke purifying cost is decreased, and the irregular ash falling device is applicable to the arrangement of ash buckets of boilers of different types.
Description
Technical field
The invention belongs to boiler component technical field, be specifically related to a kind of special-shaped ash dropped unit.
Background technology
Ash dropped unit is as important parts in boiler, and its Main Function assembles and automatically discharges lime-ash.When entering ash bucket containing the flue gas of a large amount of dust and colliding ash bucket inwall, fly ash granule directly falls into ash bucket, but the flying dust dropped in ash bucket can be involved in flue gas by larger negative pressure again, produces to return gas and carry phenomenon secretly.Fly ash granule is thinner, and ash bucket returns gas and carries secretly more serious, actual fall grey effect unsatisfactory, cause fly ash content in flue gas obviously not reduce, thus flying dust processing cost is high.In addition, common ash dropped unit, in order to connect boiler export flue, needs mounting interface, bend pipe etc., and required installing space is larger.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of nothing and returns gas and carry that phenomenon, cleaning efficiency are high, the ash dropped unit of compact conformation secretly.
Solve the problems of the technologies described above, technical scheme of the present invention is as follows:
A kind of special-shaped ash dropped unit, comprise anterior ash bucket, rear portion ash bucket, manhole access door, rotation unloading valve, described anterior ash bucket is connected with boiler back end ductwork, described rear portion ash bucket is connected with boiler export flue, described anterior ash bucket and rear portion ash bucket communicate, described anterior ash bucket and ash bucket junction, rear portion arrange groove profile segregator, and described groove profile segregator is in tilted layout.Its middle front part ash bucket and rear portion ash bucket can adopt subsection setup, are made up of upper and lower ash bucket, and upper and lower ash bucket can adopt band steel reinforcement of weld to connect.Manhole access door is arranged on anterior ash bucket and rear portion ash bucket, clean, the inspection and maintenance of ash bucket can be convenient to, install under anterior ash bucket, rear portion ash bucket and rotate unloading valve, rotate unloading valve by successive ash discharge, avoid the fly ash granule gathered again to be involved in flue gas.For ensureing the rigidity requirement of ash bucket, anterior ash bucket, rear portion ash bucket outer wall can be provided with modal circumferential stiffening rib and vertical strengthening ribs, and select shaped steel to reinforce.
Further, the width of described rear portion ash bucket is identical with the width of boiler export flue.
Further, described anterior ash bucket and rear portion ash bucket are W shape pattern, and the exit normal of described rear portion ash bucket is arranged.
Further, described anterior ash bucket and the L-shaped pattern of rear portion ash bucket, the outlet of described rear portion ash bucket is horizontally disposed with.
Further, described anterior ash bucket and the V-shaped pattern of rear portion ash bucket, the outlet-inclined impeller vane of described rear portion ash bucket is arranged.
Further, the angle of inclination of described groove profile segregator is identical with anterior ash bucket inclination angle.
Further, described groove profile segregator adopts stainless steel material.
Further, described groove profile segregator arranges many rows, and in being staggered in arrangement.
Further, the junction of groove profile segregator is set and rear portion ash bucket exports and boiler export flue is wide.
Operation principle of the present invention is: because fly ash granule in flue gas and air-flow exist inertia difference, anterior ash bucket inwall first can be clashed into when the flue gas containing a large amount of dust enters anterior ash bucket, isolate a part of flying dust, enter in groove profile segregator cell body afterwards, major part flying dust can along the downward landing of groove profile segregator cell body, fall in ash bucket, air-flow then walks around groove profile segregator, when entering rear portion ash bucket again, clash into rear portion ash headwall again, isolate again a part of flying dust, thus achieve the object of flying dust in separating flue.
Beneficial effect of the present invention is as follows:
1. the setting of anterior ash bucket and rear portion ash bucket, is conducive to the welded and installed of groove profile segregator;
2. ash bucket can be arranged in multiple pattern, adapts to dissimilar boiler construction;
3. anterior ash bucket and ash bucket junction, rear portion arrange groove profile segregator, can flying dust in separating flue, reduce fly ash content in flue gas, avoid ash bucket to produce returning gas carrying phenomenon secretly, and ash-removal effect is remarkable, reduces gas cleaning cost;
4. anterior ash bucket entrance width is identical with boiler back end ductwork width, rear portion ash bucket width is identical with boiler export flue width, anterior ash bucket then can be made directly to be connected with exhaust pass with boiler back end ductwork with rear portion ash bucket, without the need to mounting interface, bend pipe etc., make structure space more compact, space availability ratio is high;
5. groove profile segregator layout angle is identical with anterior ash bucket inclination angle, is conducive to flying dust and directly slips in ash bucket, reduces dust stratification;
6. groove profile segregator adopts stainless steel material, can avoid aggressive matter corrodes in waste incineration;
7. groove profile segregator adopts many row's groove profile segregators and in being staggered in arrangement, then can improve separating effect;
8. the junction of groove profile segregator is set and rear portion ash bucket exports and boiler export flue is wide, is convenient to arrange groove profile segregator;
To sum up, after adopting said structure of the present invention, can a large amount of dusts effectively in separating flue, avoid ash bucket to produce returning gas carrying phenomenon secretly, ash-removal effect is remarkable, reduces gas cleaning cost, and the ash bucket be applicable under dissimilar boiler construction is arranged.
