Abstract

The utility model relates to the technical field of coal-firing, in particular to a highly effective environment-friendly type hot-air furnace with a movable horizontally-reciprocating grate. The highly effective environment-friendly type hot-air furnace with the movable horizontally-reciprocating grate comprises a heat exchanging body, a combustion chamber, a horizontally-reciprocating grate, an air feeding system, a smoke discharging system and a mechanical driving system, the furnace is characterized in that the horizontally-reciprocating grate, the driving system of the grate, and the air feeding system are integrally arranged on a wheel, the wheel is arranged on a slide way or a flat ground, a locating block is arranged on the bottom of the heat exchanging body, and the horizontally-reciprocating grate integrally linked with the heat exchanger through a pin or a screw bolt.

Description

Has portable horizontal reciprocal grate high-efficiency environment friendly hot-blast stove

Technical field

The utility model relates to the coal combustion technology field, especially has portable horizontal reciprocal grate high-efficiency environment friendly hot-blast stove.

Background technology

In the middle of the Chinese patent bulletin CN2338698 (patent No. 98228773.9 pipe free hot-blast stoves), have cold air duct and hot-air channel and be folded in cold air duct spiral exhaust gases passes between the hot-air channel is arranged, its hot-air channel is a helical duct, this design thermal efficiency height, and heat exchange is abundant.But owing to adopt hand fired grate, in continuous running, because off and on toward grate upslide coal combustion, exist the periodicity of burning, when coal just has been added on the burning zone on the siege, the thickening of grate coal seam thickness, flowing resistance increases, and the air capacity that sees through the coal seam reduces.So high temperature anoxic imperfect combustion situation just occurs, produce dense black smoke, thereby cause serious air environmental pollution.In recent years, many enterprises adopt known reciprocating fire grate to transform the burner of hot-blast stove, because the continuous reciprocating motion of fire grate, slowly move from front to back in the coal seam, enter the heat radiation that is subjected to face arch and high-temperature flue gas behind the burner hearth, preheating destructive distillation gradually, separate out volatile matter such as moisture and fire burns, combustible gas that produces in the combustion reaction and black smoke are from face arch flow through the backward high temperature combustion zone and the burning-out zone at middle part, most after-flames before leaving burner hearth, simultaneously, the extruding before and after the coal of burning not only is subjected in the process of advancing, dashing about also being subjected to simultaneously fallen, stir, coal can fully be burnt, so tool smoke medicining section coal effect preferably.But this reciprocating fire grate is owing to be combined in one with hot-blast stove, and its fire grate used after a period of time must repair and replacement, owing in the stove face arch rear arch is arranged, the people will enter very difficulty of maintenance, extremely inconvenience.Simultaneously, after the breeze burning-out zone in coal seam fell down, under the wind-force effect of blower fan, the carbon ash flew away everywhere, polluted the shopwork environment.

Summary of the invention

The utility model provides to have portable horizontal reciprocal grate high-efficiency environment friendly hot-blast stove just at above technical problem, also has water seal tank simultaneously, and it can solve the maintenance and inspection of reciprocating fire grate, can eliminate the pollution of carbon ash again, prevents that cold air from sealing in the burner hearth.

The utility model is achieved through the following technical solutions.With reciprocating fire grate and supporting blower fan thereof, transmission device, be connected into an integral body by channel-section steel, angle bar etc., in its bottom four wheels is set, other establishes two with parallel track, the reciprocating fire grate integral body that four wheels supports places on the track, and fire grate and transmission device integral body thereof can push burning position easily or release maintenance.Seal with insulation material around the fire grate, positioning baffle is arranged and have the hole in the hot-blast stove bottom, for the propelling or the release that can make things convenient for fire grate, the heat exchange body portion of hot-blast stove, near the position, preheating zone, upwards open circular arc or square breach at furnace base, as burner hearth face arch position, at burning-out zone over against the coal bunker position, in the furnace base position that makes progress, open circular arc or square breach, as burner hearth rear arch position, in left or right close furnace base position, open a circle or square opening and do a wicket, as igniting or observation usefulness, on ground, position, burning-out zone carbon slag whereabouts, dig a washing basin, the pond was filled with water and is sealed with dodge gate when fire grate used.

The beneficial effects of the utility model are, when needs maintenance reciprocating fire grate or its transmission device, taking off alignment pin just can move reciprocating fire grate to body of heater and overhaul outward, the carbon slag that produces in combustion process at the coal on the fire grate falls down from burning-out zone, all enter in the pond, the carbon ash is absorbed not by the water surface can contaminated air, the while water surface has been blocked the outer cold air of stove and has been sealed in the burner hearth, improved combustion thermal efficiency, above the inlet of coal and above the burning-out zone, the high temperature of burner hearth can carry out heat exchange by chimney arch position (being hot-blast stove heat exchange body bottom), with the past handwarmer be vertical cube to the furnace wall heat exchange compare, increased the hot-blast stove heat exchange area, improved the thermal efficiency, reality be fuel with the coal, the burning, heat exchange, smoke abatement and dust control is finished in an equipment.
