Description

The energy saving and environment friendly multi-functional water heater of reversal-flame type

Technical field: the utility model relates to water heater, the energy saving and environment friendly multi-functional water heater of particularly a kind of reversal-flame type.

Background technology: water heater complex structure of the prior art, heat utilization efficiency is low, boiler for example, it needs special environment for use and professional to use, from its existing structure, its combustion chamber is in flue, if fuel is coal, coal preheat temperature around the flue is absorbed by flue, thereby causes coal combustion incomplete.The space of courage inner combustion chamber is excessive in addition, cause stove fire long to the ray of other position heat transmission of courage, thereby thermal absorptivity weakens.Moreover chimney is a straight-line, and the heat that is not in time absorbed is directly discharged from chimney, and carries volume of smoke secretly.Not only energy-saving effect is poor, and contaminated environment, and it can only use as water heater, can not use by the double as kitchen range, and purposes is single.

Summary of the invention: the purpose of this utility model is to provide a kind of reversal-flame type energy saving and environment friendly multi-functional water heater, its tempering function makes burning more complete, heat more can fully be absorbed by water heater, and can reduce soot emissions effectively, thereby reach the purpose of energy-saving and environmental protection, can not only provide hot water, boiling water and steam, but but also the use of double as kitchen range can reach multi-functional purpose again.

Formation of the present utility model: by last sump, following sump and combustion chamber are formed, around combustion chamber 12 and air preheat storehouse 5 is sump 3 under the annular, above following sump 3, install sump 15, last sump 15 and following sump 3 are by sump connecting leg 17 connections up and down, on last sump 15, vent 1 is arranged, form annular main tempering storehouse 4 between combustion chamber 12 and air preheat storehouse 5 and the following sump 3, main tempering storehouse is connected with a pair tempering storehouse 9 with flue dust falling storehouse 6 by the main tempering storehouse outlet 8 of below, it below combustion chamber 12 air preheat storehouse 5, it below the air preheat storehouse cinder chamber 7, on the sump water level displaying tube 24 and thermometer 23 being housed up and down, relief valve 25 and escape pipe 26 are housed on last sump 15.

On the sump 3 door 13 of lighting a fire is being arranged down, hook ash door 10 is arranged on the air preheat storehouse 5 below the grate 11, sump soil-shifting door 16 on the downside of last sump 15 has, downside at following sump 3 has following sump soil-shifting door 20 and blow-off pipe 22, water inlet pipe 19 is arranged on the side, and falling after rise at flue dust has flue dust to remove door 21 on the storehouse 6.

Compared with the prior art, the utility model provides a kind of of many uses, has water heater simultaneously, kitchen range are the comprehensive water heater of one, particularly a kind of reversal-flame type water heater, its tempering function makes burning more complete, heat more can fully be absorbed by water heater, and can reduce soot emissions effectively, not only can provide hot water, boiling water and steam, but also but the double as kitchen range use, simple to operate, do not need particular surroundings and full-time staff, its most outstanding advantage is energy-saving and environmental protection.

The specific embodiment: as Fig. 1, shown in Figure 2, around combustion chamber 12 and air preheat storehouse 5 is sump 3 under the annular, above following sump 3, install sump 15, last sump 15 and following sump 3 are by sump connecting leg 17 connections up and down, on last sump 15, vent 1 is arranged, form annular main tempering storehouse 4 between combustion chamber 12 and air preheat storehouse 5 and the following sump 3, main tempering storehouse is connected with a pair tempering storehouse 9 with flue dust falling storehouse 6 by the main tempering storehouse outlet 8 of below, fire-returning ring 2 is arranged above combustion chamber 12, the below is air preheat storehouse 5, it below the air preheat storehouse cinder chamber 7, on the sump water level displaying tube 24 and thermometer 23 being housed up and down, relief valve 25 and escape pipe 26 are housed on last sump 15.

On the sump 3 door 13 of lighting a fire is being arranged down, hook ash door 10 is arranged on the air preheat storehouse 5 below the grate 11, sump soil-shifting door 16 on the downside of last sump 15 has, downside at following sump 3 has following sump soil-shifting door 20 and blow-off pipe 22, water inlet pipe 19 is arranged on the side, on flue dust falling storehouse 6, there is flue dust to remove door 21, on pair tempering Cang9Kou, the chimney flange 14 that is connected with chimney arranged.

Operation principle: as shown in Figure 1, down open the door 13 of lighting a fire, open vent 1 again, light a fire and close after adding material, fire sump 15 bottoms and following sump 3 upper walls in the fiery calcination, after-heat is back into main tempering storehouse 4, sump 3 bottoms absorb under the heat quilt, when last waste heat enters in pair tempering storehouse 9 by main tempering storehouse outlet 8, once more by following sump 3 sidewall dampen outs, last remainder of exhaust gas enters chimney by chimney flange 14 and discharges, and this process is the absorbed process of heat.The required oxygen of combustion process in the combustion chamber 12 is after entering by cinder chamber 7, be preheated by time in the air preheat storehouse 5, air after the preheating enters the combustion chamber 12 combustion-supporting from grate 11, the effect multiplication, make that the burning in the combustion chamber 12 is more complete, thereby enough heats are provided, reach purpose of energy saving.

The flue dust that burning produces falls after rise in the storehouse 6 owing to no longer being subjected to the upwards impact of heating power to stay in flue dust after falling back in the flue dust falling storehouse 6 by main tempering storehouse 4, no longer passes outside the chimney, so relative environmental protection.

The use of water heater as shown in Figure 2, open escape pipe 26, from water inlet pipe 19 water inlets, close blow-off pipe 22, boiling water hot-water line 18 and flue dust and remove door 21, when water level displaying tube 24 places show the appropriate location, stop to supply water, close escape pipe 26, fire, when treating that thermometer 23 demonstrations 90～100 are spent, can use boiling water, hot water by boiling water hot-water line 18.Because last sump is provided with relief valve 25, thus high pressure do not produced in the water heater, thus can relieved safely use, open sump soil-shifting door 16 and following sump soil-shifting door 20 after using appropriate time, take out stains, at ordinary times from blow-off pipe 22 blowdowns.Sump is by sump connecting leg 17 connections up and down up and down, if when using kitchen range, disassemble sump connecting leg 17 top connections up and down, taking off sump 15 can use, and can pass through sump 3 heat production water down simultaneously, being provided with the convex-concave step up and down between the sump can cooperate voluntarily, opens flue dust after use a period of time and removes door 21, and inspection falls flue dust accumulation situation and discharge in time during the period after rise.
