Abstract

The utility model relates to a fire stew pot stove field, provide a burning furnace is fired in modified anticorrosion, including furnace, the furnace lower part is equipped with furnace slag chamber, be equipped with coal mouth, exhaust port on the oven on furnace upper portion, the oven outside of five faces of furnace is covered by the one deck insulating layer, the insulating layer outside is equipped with the heat preservation, the heat preservation is built as the adhesive with the mortar that high temperature resistant mud, cement, river sand mixture formed by the cement hollow brick, the heat preservation outside is equipped with anti -corrosion coating, be equipped with a grate between furnace and the furnace slag chamber, the furnace slag chamber left side is equipped with the air intake, and its right side is equipped with row cinder notch. The utility model discloses can prevent effectively that aggressive fume corrodes during the oven is by the air, basically the phenomenon that the furnace body is corroded can not appear, simultaneously, improve the heat preservation effect of furnace body, reduce scattering and disappearing of heat energy to reduce the consumption of burning coal, reduced manufacturing cost.

Description

A kind of modification anticorrosion combustion furnace

Technical field

The utility model be related to burning boiler field and in particular to a kind of modification anticorrosion combustion furnace.

Background technology

In enterprise produces, provide the equipment of heat to have various combustion furnaces for it, typically adopt at present and be situated between for burning with coal The boiler of matter, the outer protection device of boiler is generally the iron sheet that boiler is separately installed after manufacturer dispatches from the factory, this kind of boiler Design, is easy to the transport of boiler, but in production and application boiler process, because of Long-Time Service, body of heater inside thermal conservation material is made because of heating power With, impaired after, the oxidation of body of heater iron sheet can be accelerated, meanwhile, the in the air of many factories boiler shop has micro acidic materials, The corrosion of boiler face can be accelerated, if after body of heater damages, its heat insulation effect extreme difference, boiler combustion consumption of coal is bigger, and production cost is significantly Improve.

Content of the invention

The utility model is exactly to solve above-mentioned technical problem, provides a kind of high insulating effect, and what body of heater was difficult to be corroded changes Property anticorrosion combustion furnace.

Technical problem of the present utility model is mainly addressed by the following technical programs：A kind of modification anticorrosion burning Stove, including burner hearth, lower furnace portion is provided with slag room, and the furnace wall of described upper furnace is provided with coal filling hole, exhaust opening, described burner hearth Covered by one layer of thermal insulation layer outside the furnace wall in five faces, outside described thermal insulation layer, be provided with heat-insulation layer, described heat-insulation layer is empty by cement Heart brick is built into as adhesive with the mortar that high temperature resistant mud, cement, river sand mix, and is provided with anticorrosion outside described heat-insulation layer Layer, is provided with a fire grate, is provided with air inlet, is provided with slag-drip opening on the right side of it on the left of described slag room between described burner hearth and slag room.

Specifically, described thermal insulation layer is made up of rock cotton board, and thickness is 5～10cm.

Specifically, described high temperature resistant mud adopts DR-A3-JH-2 type fire-proof mud.

Specifically, described corrosion-resistant coating is made up of DR-A3-JH-2 type fire-proof mud, and thickness is 2～5cm.

The beneficial effects of the utility model are：In the utility model, asbestos board thermal insulation layer is set outside the furnace wall of burner hearth, There is good insulation insulation effect, reduce heat in burner hearth and outwards scattered and disappeared by furnace wall, set hollow cement brick making heat-insulation layer profit Form air layer with hollow cement brick making hollow interlayer and further function as heat insulation effect, also stop external corrosive gas to enter simultaneously Contact furnace wall, plays the effect preventing furnace wall to be corroded, and set corrosion-resistant coating adopts DR-A3-JH-2 type fire-proof mud, DR-A3- JH-2 type fire-proof mud has high, the good plasticity of fire endurance, acidproof, alkaline-resisting, corrosion resistance, and construction, maintenance are more convenient, Furnace wall can be effectively prevented corroded by the air corrosive gas, thus protecting normally transporting steadily in the long term of whole burner block OK, using the utility model, be not in the phenomenon that body of heater is corroded substantially, improve the heat insulation effect of body of heater meanwhile, reduce Scattering and disappearing of heat energy, thus decreasing the consumption of burning coal, reduces production cost.

Specific embodiment

Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is further described.

A kind of modification anticorrosion combustion furnace, including burner hearth 11, burner hearth 11 bottom is provided with slag room 8, the stove on burner hearth 11 top Wall 4 is provided with coal filling hole 9, exhaust opening 10, is covered by one layer of thermal insulation layer 3, outside thermal insulation layer 3 outside the furnace wall 4 in 11 5 faces of burner hearth Side is provided with heat-insulation layer 2, and heat-insulation layer 2 is made adhesive by hollow concrete block with the mortar that high temperature resistant mud, cement, river sand mix and built Become, be provided with corrosion-resistant coating 1 outside heat-insulation layer 2, between burner hearth 11 and slag room 8, be provided with a fire grate 5, be provided with the left of slag room 8 into Air port 7, is provided with slag-drip opening 6 on the right side of it.

Thermal insulation layer 3 is made up of rock cotton board, and thickness is 6cm.High temperature resistant mud adopts DR-A3-JH-2 type fire-proof mud.Corrosion-resistant coating 1 is made up of DR-A3-JH-2 type fire-proof mud, and thickness is 3cm.

The present embodiment is the embodiment of the utility model example, for those skilled in the art, at this It is easy to making various types of improvement and deforming on the basis of utility model discloses application process and principle, and not only limit In the structure described by the above-mentioned specific embodiment of the utility model, therefore, previously described mode is preferred version, and simultaneously Not restrictive meaning, every equivalence changes made according to the utility model and modification, all will in the utility model right Ask in the scope protection domain of book.
