A kind of mesh-belt kiln remodeling method, SCR denitration high-efficient roasting equipment are to pass through the mesh-belt kiln remodeling method Improved roasting apparatus, which is characterized in that the mesh-belt kiln remodeling method the following steps are included:
Step 1: increasing roasting 17 space of main body: roasting 17 furnace roof steelframe crossbeam of main body and furred ceiling cotton folded piece are increased, Furnace roof steelframe crossbeam is fixed with long and narrow shaped steel frame main body wall using outer bolt, while upper electric heating layer 9 being improved to away from mesh belt Carrying roller 4 is to 443mm;
Step 2: installing major diameter exhaust system additional: waste discharge feed channel 3 increases to 300 by 250 original ~ 350mm ~ 2 caliber of exhaust branch pipe is increased to φ 200mm by 400mm, adds thiamines clean-up port 12 in 2 upper surface of exhaust branch pipe, lower surface is set Thiamines discharge outlet is set, thiamines discharge outlet is not drawn into figure;
Step 3: increasing the bearing capacity of conveyer system: by the mesh belt carrying roller 4 of conveyer system and rewinding carrying roller 7 by original 50 × 3mm of φ is changed to φ 60 × 4mm stainless steel carrying roller, and accordingly replaces to bearing, SCR denitration high-efficient roasting equipment Silicon-controlled heating module, control element, power control cabinet and cable bridge it is consistent with mesh-belt kiln, so far, mesh-belt kiln transformation complete.
(1) mesh-belt kiln support system: on the basis of former mesh-belt kiln steelframe main body, furnace roof steelframe crossbeam and furred ceiling cotton are rolled over It is horizontal concordant with furnace roof that folded block increases 138mm(), i.e., mesh belt shares 443mm apart from upper layer electric heating layer, can satisfy the double-deck production The height requirement that product load changes the installation method of former anchoring piece in furnace roof: passing through kiln top steel plate using anchoring piece bolt It is fixed using outer bolt, keeps structure more firm, the original mesh belt of equipment has 305mm apart from upper layer electric heating layer, also phase after transformation It should be promoted;
(2) electric heating system: after the completion of furnace insulation cotton folded piece is built, top electric heating tube aperture is mentioned on side wall High aperture (mesh belt lower layer is constant, and upper layer correspondinglys increase) again, electric heating subregion is constant.Former mesh-belt kiln electric heating installed power is 330kw, actual motion power is about in 80-100kw or so (with reality after being stablized according to the production of previous experiences data original equipment Production status is related), electric heating has biggish surplus capacity, therefore is not required to additionally increase electrical heating power again;According to being transformed simultaneously Producer's creation data of normal operation, about in 130kw, energy consumption of unit product will reduce the operation power after transforming bilayer as.
(3) waste discharge pipeline: the substances such as sulphur ammonia generated after transformation by calcining double, and waste discharge main pipeline need to be by original 250/ φ 350 of φ increases to 300/ φ 400mm of φ, and waste discharge branch pipe is all changed to fan housing exhausting by original dotted extraction Formula, and branch diameter is increased into φ 200mm, and increase several thiamines clean-up ports and bottom thiamines discharge outlet on pipeline, with Facilitate the cleaning of sulphur ammoniacal substance in daily production process.
(4) transmission system: because mesh belt after transformation and carrying roller load-bearing increasing are twice, carrying roller is easier bending deformation, therefore needs Full kiln carrying roller is changed to φ 60 × 4mm stainless steel carrying roller by original 50 × 3mm of φ, all bearings are accordingly replaced.Product Firing period still remains original, to guarantee product firing quality and mitigate mesh belt and carrying roller load.
(5) control system: silicon-controlled heating module, control element, power control cabinet, cable testing bridge etc. can be with former mesh-belt kilns one It causes, does not need additionally to increase cost.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, made any modification, equivalent replacement, transformation etc. should be included in the guarantor of the utility model Within the scope of shield.
