Abstract
The invention belongs to the technical field of electricity generation by ferrosilicon smelting flue gas waste heat, and particularly relates to a method for cleaning soot of a ferrosilicon smelting flue gas waste heat boiler. The method adopts a mechanical scratch brushing way, namely a circular brush or a full circular brush which is assembled by two semicircles is adopted; the brush hair is made of a metallic filament or metallic filament flat-clew-shaped material; the brush is sheathed outside a heat-transfer pipe; then a plurality of brushes are connected into an integral grid structure; the grid structure is connected with a metal wire frame and driven by a hoisting machine, a speed reducer and a motor system; the system is provided with various protecting and controlling devices; and a PLC is adopted for controlling. The method ensures that a plurality of brushes conduct back and forward movements on the outer wall of a heat-transfer component under the driving of a motor to remove the soot adhered on the wall, therefore the normal operation of the boiler is guaranteed.
Description
One, technical field:
The invention belongs to the power generation by ferrosilicon smelting flue gas waste heat technical field, relate in particular to a kind of ash removal method of waste heat boiler of power generation by ferrosilicon smelting flue gas waste heat.
Two, technical background:
In the production process of ferrosilicon smelting, can produce a large amount of useless flue gases on the ferrosilicon smelting electric furnace, the temperature of these flue gases is used further in the ferrosilicon smelting with these high-temperature flue gas recovery waste heat generatings up to 400～800 ℃, and this part invention has been succeeded in developing by the applicant and declared patent.But in the process of its project implementation, run into a technical barrier, it is exactly that these high-temperature flue gas are carrying a large amount of very thin particles, its viscosity high adsorption is stronger, amount is big, equipment has stoped the heat transmission on when operation, these dust just were easy to stick to tube wall in the waste heat boiler, the heat that makes boiler can not effectively absorb in the flue gas can not the operate as normal generating.And adopt ash removal methods such as existing shock wave, rapping, the ball that falls all can not solve its a deashing difficult problem, and researcher of the present invention has just found a kind of effective ash removal method through repeatedly repetition test research.
Three, summary of the invention
The objective of the invention is the problems referred to above at the prior art existence, a kind of new ash removal method of design studies, the method can solve the deashing difficult problem of prior art fully, the ferrosilicon smelting flue gas waste heat boiler can normally be moved, and this method mentality of designing is ingenious, and method is simple, is convenient to implement, easy to operate, equipment investment is also little.
Its technical scheme is: the ash removal method of this ferrosilicon smelting flue gas waste heat boiler is characterised in that; it adopts the version of mechanical brushing; its concrete structure is for adopting round-type brush; or be the brush of a full circle after the assembling of two semicircles; the bristle of brush is wire or wire lenticular wire bulk structure; each brush is set in outside the heat-transfer pipe in the boiler; again these a plurality of brushes are linked as integral body by elastic compensating device; this connects integral body is grid structure; grid structure links to each other with metal truss; metal truss is by hoist engine; decelerator; electric motor system drives, and this system is provided with various protections and control device, and PLC control is adopted in its control.The machinery brushing is the brush made from wire or wire lenticular wire bulk structure, brush is sleeved on the heat conductive wall that needs brushing, these brushes drive its motion by mechanism, thereby the realization brushing falls to adhere to the particle dust that the obstruction on the heat conductive wall is conducted heat.Brush is a circular configuration, is that the bristle of brush is wire or wire lenticular wire bulk structure because the waste heat boiler heat transfer component is circular pipe fitting, and bristle is an environment temperature height in very high dust of brushing viscosity and the boiler, so should adopt the bristle of metal material.Elastic compensating device designs for the distortion that solves heat-transfer pipe and device, and its metal brush is unaffected when distortion occurring, and brush is a consumable accessory, can often change.A plurality of brushes connect as a whole grid structure, and grid structure links to each other with metal truss, and metal truss is driven by the power part that hoist engine, decelerator, motor are formed again.Protection and control device are to the brush device that whole brushing process is protected and controlled in waste heat boiler, it be designed to prior art, stating no longer here more.In the use, the outer wall of a plurality of brushes heat transfer component in waste heat boiler under the drive of motor moves back and forth, thereby the dust that influences heat-transfer effect that will adhere on the wall removes, and has guaranteed the normal operation of waste heat boiler.
Four, the specific embodiment:
Embodiment 1: in ferrosilicon smelting factory of our company; smoke and waste steam boiler is installed; in this waste heat boiler, adopt ash removal method of the present invention; brush is made circle; bristle is made with the wire material; each brush is sleeved on outside the heat-transfer pipe; these a plurality of brushes are connected to grid structure with elastic compensating device; grid structure links to each other with metal truss; the dynamical system that metal truss is made up of hoist engine, decelerator, motor drives; this system is provided with regularly, the protection and the control device of location, and its control is controlled with PLC.This embodiment is succeedd in the pilot scale of our company, and ash-removal effect is good.
Embodiment 2: it is identical with embodiment 1 basically; its difference is that brush is the brush that two semicircle assembling backs become a full circle; bristle is made with wire lenticular wire bulk structural material; protection and control device not only are provided with regularly in addition, positioner; but also being provided with probe apparatus, its ash-removal effect is good.
