Technical field
The utility model belongs to the hot-water boiler apparatus field, especially a kind of energy-conservation low pressure hot water boiler.
Background technology
Hot-water boiler is the firing equipment of using always; Its structure is: comprise housing 2, be provided with cinder chamber 20 in the housing lower end, top, cinder chamber is a lower combustion chamber 22; The two is separated through fire grate 19; Be provided with baffling pipe 3 in the housing above lower combustion chamber, this baffling pipe connects water filling port 4, the delivery port 1 of setting-in on the housing and lets out residual mouthful 17, and housing also is communicated with air-introduced machine 9 through smoke exhaust pipe 5.In the said structure, lower combustion chamber's direct baking baffling pipe makes the water in the baffling pipe be heated and offer miscellaneous equipment uses such as heating installation; Such mode of heating heat exchanger effectiveness is low; Most of heat is along with flue gas is discharged, and not sufficient and water carries out heat exchange, and the flue-gas temperature of the air-introduced machine outlet that generally records is about 400 degree; And the content of dust is also very high in these flue gases, and the lot of consumption of energy does not meet the needs of national energy-saving and emission-reduction.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of energy-conservation low pressure hot water boiler simple in structure is provided.
The technical scheme that the utility model is taked is:
A kind of energy-conservation low pressure hot water boiler; Comprise housing, lower combustion chamber, cinder chamber, baffling pipe and air-introduced machine; It is characterized in that: also comprise a heat exchange cabinet and a upper combustion chamber, upper combustion chamber is arranged on lower combustion chamber top and the two is separated through spaced many water pipes, and setting-in lets out the water jacket that is provided with in residual mouthful and the integrally formed heat exchange cabinet of housing sidewall on these many cross current housings; This water jacket upper end is communicated with the upper combustion chamber interior water filling cavity of upper plate upper shell; The smoke pipe lower end that is uniformly distributed with arrangement in the water jacket is communicated with the cinder chamber, and the upper end of smoke pipe is communicated with the baffling pipe, and the baffling pipe is communicated with the input of a secondary heat exchange dust arrester through the smoke exhaust pipe of setting-in on the housing; The output of this secondary heat exchange dust arrester is communicated with air-introduced machine, and said water filling cavity is communicated with water filling port and the delivery port that is provided with on the housing.
And; The structure of said secondary heat exchange dust arrester is: comprise shell, exchange water jacket, heat exchanger tube and residual cake valve, the exchange water jacket is installed in the shell, be uniformly distributed with in this exchange water jacket a plurality of heat exchanger tubes are installed; The upper end of one side heat exchanger tube is communicated with said smoke exhaust pipe; The upper end of opposite side heat exchanger tube is communicated with air-introduced machine, and the lower end of this both sides heat exchanger tube all is communicated with the dirt pocket that the lower end is provided with in the shell, water-filling in this dirt pocket; Setting-in residual cake valve on the shell of dirt pocket lower end, said exchanged water cover is communicated with the cold water outlet and the hot water mouth of setting-in on the shell.
The advantage and the good effect of the utility model are:
The utility model is simple in structure, on conventional boiler, has increased upper combustion chamber, heat exchange cabinet and secondary heat exchange dust arrester, and is coal-fired after upper combustion chamber's burning; At first with the heating of the water in the water pipe, promptly realized heat exchange for the first time, the coal-fired then hot flue gas that produces gets into the heat exchange cabinet through lower combustion chamber and cinder chamber; In the heat exchange cabinet, carry out heat exchange through the water in the water jacket of smoke pipe and heat exchange cabinet, promptly realized heat exchange for the second time, hot then flue gas gets into secondary heat exchange dust arrester through the baffling pipe; In the baffling pipe spirals the process of advancing, realized with housing in the heat exchange for the third time of water of upper end because hot flue gas is through repeatedly heat exchange; So can in the unit interval, heat more water, operating efficiency is very high like this, and hot flue gas carries out the 4th heat exchange in secondary heat exchange dust arrester; This part heated water can also can be back in the boiler for uses such as shower, and hot flue gas has carried out dust removal process in secondary heat exchange dust arrester; The flue gas particle content that air-introduced machine is discharged greatly reduces; Protected environment, through field survey, the hot flue-gas temperature of air-introduced machine outlet is about 90 degree; It is thus clear that the efficient of heat exchange is very high, has practiced thrift the energy.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.
A kind of energy-conservation low pressure hot water boiler; As shown in Figure 1; Comprise housing 2, lower combustion chamber 22, cinder chamber 20, baffling pipe 3 and air-introduced machine 9, separate through common cast iron fire grate 19 between lower combustion chamber and the cinder chamber that the innovation of the utility model is: also comprise a heat exchange cabinet 14 and upper combustion chamber 23; Upper combustion chamber is arranged on the lower combustion chamber top and the two is separated through spaced many water pipes 18; On these many cross current housings setting-in let out residual mouthfuls 17 with the integrally formed heat exchange cabinet of housing sidewall in the water jacket 16 that is provided with, this water jacket upper end is communicated with the upper combustion chamber interior water filling cavity 25 of upper plate 24 upper shell, smoke pipe 15 lower ends that are uniformly distributed with arrangement in the water jacket are communicated with the cinder chamber; The upper end of smoke pipe is communicated with the baffling pipe; The baffling pipe is through the input of the smoke exhaust pipe 5 connections one secondary heat exchange dust arrester of setting-in on the housing, and the output of this secondary heat exchange dust arrester is communicated with air-introduced machine, and water filling cavity is communicated with the water filling port 4 and delivery port 1 that is provided with on the housing.
