Abstract
The utility model relates to a convex ridge guide plate arranged in a wet sulfur removal process chimney. A central line of a convex ridge (1) is superposed with that of a chimney inner sleeve; and the two sides of the convex ridge (1) incline for 45 degrees downwards. A flat slope guide plate at the bottom part of the chimney inner sleeve is changed into a guide plate structure that a ridge bulges, and the two sides incline downwards, so that condensate is not retained at the bottom part of the chimney inner sleeve. In the utility model, the guide plate structure is processed by a titanium clad steel plate identical with the chimney inner sleeve in material.
Description
Technical field
The utility model relates to the built-in convex ridge deflector of flow-guiding structure device, especially wet desulphurization technology chimney in the fume gas condensation liquid draining diversion technology in the limestone-gypsum wet desulphurization chimney.
Background technology
In the known technology along with country to the promoting the use of of sulfur removal technology in the fired power generating unit smoke gas treatment, limestone-gypsum wet desulphurization technology is extensive use in existing coal-fired unit transformation and 300MW and above coal-fired unit are newly-built.In adopting the engineering of this sulfur removal technology, inner wall of stack will produce in large quantities that fume gas condensation liquid catchments and need efflux.
The sulphur removal fume gas condensation liquid drainaging scheme that adopts usually that catchments has following several kinds in the chimney:
Scheme one: the place offers discharge outlet at the grey platform of the former collection of inner wall of stack; Catchmenting in the chimney entered in the catch pit that the grey platform of chimney (sleeve) collection bottom is provided with through collecting grey platform discharge outlet, after the pump pressurization, waste liquid discharged chimney and flow into to reclaim in the raceway groove of desufurization system and use.This drainage system need increase part buildings or structures and equipment, and the improper drainage pipeline that will occur of sulphur removal drainage system operational management blocks (the mortar deposition in the chimney), directly influences the normal operation of unit.
Scheme two: the place offers discharge outlet at the grey platform of the former collection of inner wall of stack, with catchmenting through collecting grey platform discharge outlet in the chimney, on the chimney wall, reclaims in the raceway groove of tapping discharge chimney (sleeve) inflow desufurization system and uses.There are problems such as Sewer Line Distribution and insulation in this drainaging scheme.Winter operation freezes easily, blocks draining.
Scheme three: newly-built unit is used the limestone/gypsum wet desulphurization, and its draining adopts chimney inner sleeve gentle slope to arrange, directly fume gas condensation liquid is drawn chimney, by the discharge outlet that is provided with on the flue waste liquid is discharged, and in the raceway groove of pipeline inflow desufurization system, reclaims and uses.Though this drainaging scheme is superior to preceding two kinds, also exist the chimney bottom water conservancy diversion gradient little, partial structurtes have the dead angle that draining is had some setbacks, and a small amount of mortar causes the alluvial of chimney inner bottom part mortar easily, has a strong impact in the chimney sulphur removal fume gas condensation liquid problems such as discharge of catchmenting.
More than three kinds of flue gas sulphur removal condensation water emission scenaries; Different problems all appears in building up the engineering that puts into operation; The safe and stable operation of flue gas desufurization system produced seriously influenced, and will directly influence the normal operation of generating set, will produce adverse influence social and economic activities.
The rare patent application of similar techniques is open.
Summary of the invention
The purpose of the utility model technology is to catchment for condensate in the chimney a kind of new drain measure scheme is provided, and promptly provides a kind of wet desulphurization technology chimney built-in convex ridge deflector
Realize that the measure of the utility model goal of the invention comprises: convex ridge center line and chimney internal cylinder central lines; Downward-sloping 45 ° of convex ridge both sides.
In the utility model, change the flat slope deflector bottom the chimney internal cylinder into the spine downward-sloping deflector structure in protruding both sides, condensation water is not detained in the chimney internal cylinder bottom; Deflector structure adopts the titanium-steel composite board processing identical with chimney inner sleeve material in the utility model.

The specific embodiment
Below in conjunction with specific embodiment, describe:
The utility model is arranged on tube bottom in the chimney 2, convex ridge 1 center line and chimney internal cylinder central lines;
Downward-sloping 45 ° of convex ridge 1 both sides.
Convex ridge 1 edge retainer ring edge ribs 7 links to each other with chimney 2 inner tube walls; Chimney 2 inner tube walls and deflector coupling part seam crossing promptly encircle the 7 fixedly flanging 6 of installation place upsides applying of edge ribs, flanging 6 upper limb applying chimneys 2 inner tube walls; Lower edge is fitted and is encircled edge ribs 7 upsides; Flanging 6 bending parts are provided with the R=50mm rounding, prevent the local dead angle that forms, and cause the hydrops deposition.
In the utility model, convex ridge 1 both sides deflector and flanging 6 processing material requesteds are titanium one steel composite board.The smooth slyness of plane that condensation water is flowed through and seam prevents that flow is obstructed or foreign material are piled up.
Convex ridge 1 both sides deflector upside is a titanium plate 3, and titanium plate 3 downsides install and fix liner plate 4, and liner plate 4 is a blanket of glass wool, and ring edge ribs 7 is fixed on 3 times side compressions of titanium plate through angle steel 5 with liner plate 4.
The utility model; Can be under the situation that does not increase any equipment, facility; At first, change the diversion mode of existing fume gas condensation liquid, fume gas condensation liquid is not detained in chimney bottom through design to fume gas condensation liquid guiding device in the flue; And enter flue smoothly, and make sulphur removal fume gas condensation liquid catchment to enter fast in the desufurization system raceway groove through the flue discharge outlet to recycle.
The utility model satisfies the requirement of fired power generating unit sulphur removal operation fully, has solved the problem that fume gas condensation liquid catchments and discharges in thermal power plant's limestone/gypsum wet desulphurization chimney, for condition has been created in the fired power generating unit safe operation.
The application of the utility model has overcome the discharging of catchmenting in chimney of sulphur removal fume gas condensation liquid and has not freely reached problems such as floss hole obstruction, can guarantee the normal operation of desufurization system.
In above embodiment, the necessary known technology that does not reach narration no longer details.
