Description
Technical field
The utility model relates to boiler, specifically vacuum boiler.
Background technology
Existing vacuum boiler has generally included boiler body, and in boiler body, bottom is heating agent pool, is provided with flue and the convection current smoke pipe bundle of connection, is region of no pressure, is provided with heat exchanger in region of no pressure in boiler body above heating agent pool in heating agent pool.During work, fuel is in flue combustion, the heat medium water in heating agent pool is heated, rapid evaporation is to heat exchanger under vacuum conditions, cold water enters heat exchanger by the water inlet of heat exchanger, carry out heat exchange by heat exchanger and chilled water and heat up, exported by the delivery port of heat exchanger, chilled water falls after condensation backheat matchmaker pool on heat exchangers.Existing vacuum boiler is reach good heat transfer effect, and the size of heat exchanger of employing is large, length is long, there is the shortcoming of not easily installing and transporting, and is therefore necessary to improve.
Summary of the invention
The purpose of this utility model proposes a kind of vacuum boiler, it has compact conformation, be convenient to install and transport, good effect of heat exchange feature.
The purpose of this utility model realizes by following technical scheme:
Vacuum boiler, it includes the flue, smoke pipe bundle and the heat exchanger that arrange in boiler body and boiler body, and in boiler body, rear end is provided with rear smoke box, and flue rear end connects logical by smoke pipe Shu Yuhou smoke box, a smoke exhaust pipe is communicated with rear smoke box.
Described heat exchanger includes some heat exchanger tubes and multiple collecting box, the two ends collection of the many heat exchanger tubes be arranged in parallel is even formed set of heat exchange tubes by collecting box, the collecting box of adjacent two set of heat exchange tubes makes by connecting communicating pipe to lead to the heat exchanger channels forming S shape in heat exchanger, and the collecting box at heat exchanger channels two ends has water inlet and delivery port respectively.
Described heat exchanger is installed on the top of boiler body inner furnace and smoke pipe bundle, and the collecting box of heat exchanger is fixed on boiler body, and described heat exchanger includes at least 3 set of heat exchange tubes be arranged in parallel.
Prioritization scheme, smoke pipe bundle of the present utility model comprises the first return smoke tube bank and the tube bank of the second return smoke; Boiler body Inner Front End is provided with front smoke box, and flue, the first return smoke tube bank, front smoke box, the second return smoke tube bank are connected logical with rear smoke box successively; The front end of boiler body is provided with burner, and the flame jet pipe of burner stretches in the front end of flue.
Further prioritization scheme, front smoke box described in the utility model and rear smoke box adopt wetting back-type structure.
