Description
The utility model relates to a kind of follow-on double-layer grate water heater.
The double-layer grate water heater of existing market sale and public use, as the WH series household stove of Wuhan production, the LCS type drinking water boiler that Tianjin produces, the LCS type boiler for boiling water, taking a bath and heating that Beijing produces, the LSG type boiler for boiling water, taking a bath and heating that Jinan produces etc., generally constituted by body of heater, smoke pipe, flue, water-cooled grate, casting furnace grate and chimney, its stove chimney requires more than 15 meters, because the chimney pulling force is big, so exhaust gas temperature is higher, flow velocity is very fast, and flue gas is taken and wrapped up in a large amount of dust and carbon granules is discharged from chimney.Because combustion product is short at residing time in furnace, so incomplete combustion often occurs, the over-emitting black exhaust phenomenon.In addition, the smoke pipe of its stove is common garden light pipe, and heat exchange area is little, and heat transfer property is poor.So its stove heat loss is bigger, discharged flue gas also often exceeds the index that environmental protection is controlled.
The purpose of this utility model provides a kind of high-efficiency multi-function modified double-layer grate water heater.Its main points are to adopt to be provided with the protruding chamber ripple heat-transfer pipe that increases heat exchange area in stove, are provided with the heat-resistant element that absorbs waste heat at the furnace throat place, and the inwall of the furnace chamber turbulent flow helical fin that has been welded fully burns fuel gas.Therefore, the thermal efficiency of stove is significantly improved, and the pollution of fume emission is significantly improved.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, the high-efficiency multi-function water heater comprises that upper furnace body, lower furnace body, tube connector ［ 1 ］, heat-resistant element and chimney form.
Upper furnace body is to be formed by upper shell ［ 2 ］, protruding chamber ripple heat-transfer pipe ［ 3 ］, last end plate ［ 4 ］, following end plate ［ 5 ］ and tie-plate ［ 6 ］ assembly welding.Some protruding chamber ripple heat-transfer pipes are along upper furnace body inner chamber garden Zhou Junbu.Described protruding chamber ripple heat-transfer pipe inwall is the ripple type seamless steel pipe that equidistantly protrudes to the axle center, and upper and lower end plate is slightly stretched at the two ends of this pipe, and outer wall and end plate weld together.Constitute cold water between upper shell ［ 2 ］ and the protruding chamber bellows ［ 3 ］ and give hot cell ［ 7 ］.
Lower furnace body is formed by lower house ［ 8 ］, flue ［ 9 ］, upper spacer ［ 10 ］, lower clapboard ［ 11 ］, water-cooled grate ［ 12 ］ and casting furnace grate ［ 13 ］ assembly welding.It between lower house ［ 8 ］ and the flue ［ 9 ］ the boiling water chamber ［ 14 ］ of annular.Be welded with some helical fins ［ 15 ］ on the inwall of flue ［ 9 ］.The horizontal water tube of inclination is arranged in middle part welding one along flue ［ 9 ］, constitutes water-cooled grate ［ 12 ］.Casting furnace grate ［ 13 ］ is welded in the lower end of flue ［ 9 ］.Water-cooled grate ［ 12 ］ upper space is last furnace chamber ［ 16 ］, and casting furnace grate ［ 13 ］ upper space is following furnace chamber ［ 17 ］, and casting furnace grate ［ 13 ］ lower room is grey chamber ［ 18 ］.In last furnace chamber, above the water-cooled grate ［ 12 ］, the coaming plate that is welded ［ 19 ］, coaming plate ［ 19 ］ the top top board ［ 20 ］ that has been welded has constituted combustion chamber ［ 21 ］ by coaming plate, top board and water-cooled grate.
Upper and lower two bodies of heater pass through flange ［ 22 ］, ［ 23 ］ separately, are integral with bolted.Give and between hot cell ［ 7 ］ and boiling water chamber ［ 14 ］ tube connector ［ 1 ］ is housed and communicates with each other.
Spill flange ［ 24 ］ and transition segment ［ 26 ］ are housed on the tie-plate of upper furnace body ［ 6 ］, flange is built-in with several layers radiation net and works out with heatproof, corrosion resistant Aludirome material, and the inboard of tie-plate ［ 6 ］ and radiation all scribble far ultrared paint on the net.Said spill flange ［ 24 ］ and radiation net ［ 25 ］ constitute heat-resistant element.The upper flange and the chimney of transition segment ［ 26 ］ join.
Coal is thrown on the water-cooled grate ［ 12 ］ from last fire door ［ 28 ］, from top to down drying, destructive distillation and burning, combustion product flows downward, and passes water-cooled grate ［ 12 ］, is descending furnace chamber ［ 17 ］ to mix and is burning with the air that enters from upper and lower fire grate and obtain heating.Simultaneously, a part of carbon granules and lime-ash are fallen on the casting furnace grate ［ 13 ］ and are continued to burn owing to volume reduces to leak down from water-cooled grate ［ 12 ］.The flue gas that produces rises by the sideshake of last furnace chamber, is discharged by chimney through excess convexity chamber ripple heat-transfer pipe ［ 3 ］ and heat-resistant element.
The utlity model has following advantage:
1, inboard wall of furnace is welded with helical fin, and air is fully mixed under turbulent-flow conditions with fuel gas, and has prolonged the time of staying in stove, thereby promotes burning fully.
2, replace smooth garden pipe with protruding chamber ripple heat-transfer pipe, heat exchange area significantly increases, and has destroyed the thermal resistance boundary layer, has improved conductivity of heat.
3, the furnace throat place is provided with heat-resistant element, when high-temperature flue gas during by the radiation net most of heat netted absorption, in radiation is melted down again, exhaust gas temperature is suddenly descended, heat energy is fully used.Simultaneously, stop dust in flue gas, carbon particle, made it gravity and sink, reduced dust-exhausting quantity.
For this reason, this stove and accessory has thermal efficiency height, energy-conservation, the advantage of wide adaptability.Compare with water heater of the same type, exhaust gas temperature can reduce more than 50 ℃, and heat exchange area is increased to 1.5 times, and the thermal efficiency carries 10%, economizes on coal 20%.Oke exhaust blackness is a Lin Geman 0--1 level, and dust exhausting concentration is less than 150mg/Nm
3Environmentally safe.
This stove steamed rice, drinking-water, shower and heating can be carried out simultaneously, have reached multi-use.It is the ideal equipment that town and country office, school, enterprises and institutions use in the nonsmoking section.
