Abstract

The utility model discloses an energy-saving and efficient heat-exchange boiler body which belongs to the technical field of boilers and comprises a boiler body shell and a heat-exchange chamber, wherein a water inlet pipe, a water outlet pipe and a drain pipe which are communicated with the heat-exchange chamber are arranged on the boiler body shell. The boiler body is characterized in that the heat-exchange chamber is internally provided with an external fire tube and an internal fire tube; the internal fire tube is arranged in the external fire tube; the lower end of the external fire tube is connected with a bottom tube plate arranged on the bottom face of the boiler body and is communicated with the lower surface of the bottom tube plate; the lower end of the internal fire tube is communicated with a lower collecting case arranged at the lower part of the heat-exchange chamber; and the upper ends of the external fire tube and the internal fire tube are respectively communicated with an upper collecting case arranged at the upper part of the heat-exchange chamber; the lower collecting case is provided with an eduction tube, and the other end of the eduction tube is communicated with the exterior of the boiler body shell. The utility model has the advantages that the structure is compact, the manufacture is simple, a plurality of fire tubes are arranged, the heat-exchange is full, a water jacket is unclogged without dead angle, and the technical problems in the prior art that dirty is easy to accumulate and the heat exchange is inadequate are solved, thereby being an ideal heat-exchange boiler body.

Description

Efficient energy-saving heat exchange pot body

Technical field

The utility model belongs to the boiler technology field, relates to a kind of heat exchange pot body of hot-water boiler, especially a kind of efficient energy-saving heat exchange pot body.

Background technology

Known bathing of prior art or hot water boiler for heating, constitute by the heat exchange pot body and the bed of boiler that is arranged on below the heat exchange pot body, described heat exchange pot body, be provided with upper and lower backhaul fireworks channel in it, one end of fireworks channel is communicated with the burner hearth of the bed of boiler, and the other end is communicated with the chimney bottom of pot in the body; Furnace flame enters pyrotechnics pipe peripheral in pot body and goes upward to the top, encloses inwards then down and returns to the chimney bottom that is in the center, is up to a pot external body top outlet again and discharges in chimney, and fireworks channel and boiler water heat exchange stroke increase, thermal efficiency height.But its deficiency is: in the pot body inner barrel must be set, be isolated into flue and water jacket, cause becoming in the water jacket dead angle, be easy to deposit dirt, or because of under return fireworks channel the lower end directly be connected and make the fireworks channel layout less with the less chimney bottom of diameter, cause heat-transfer surface restricted, fully heat exchange.

Summary of the invention

The purpose of this utility model is to solve the prior art existence to be easy to deposit dirt, the inadequate technical problem of heat exchange, provides a kind of efficient energy-saving heat exchange pot body, to overcome the deficiencies in the prior art.

To achieve these goals, the utility model efficient energy-saving heat exchange pot body, it comprises pot body case and Heat Room, the pot body case is provided with water inlet pipe, outlet pipe and the blow-off pipe that communicates with Heat Room, its main points are to be provided with outer fire pipe and internal fire pipe in the Heat Room, and internal fire pipe is arranged on the centre of outer fire pipe; The lower end of outer fire pipe is connected with bottom tube plate on being arranged on pot body bottom surface and communicates below the bottom tube plate, the lower end of internal fire pipe is communicated with the next part case that is arranged on the Heat Room bottom, and the upper end of outer fire pipe and internal fire pipe is communicated with the upper collecting chamber that is arranged on Heat Room top respectively; The next part case is provided with fairlead, the exterior of the other end of fairlead and pot body case.

For the ease of the cleaning dust, be respectively equipped with cleaning door on said upper collecting chamber and the next part case.

Directly do not connect between the utility model outer fire pipe and internal fire pipe and internal fire pipe and the fairlead, but be communicated with by upper collecting chamber and next part case, so can free comb in the pot body, it is more that the pyrotechnics pipe is arranged, heat exchange area increases, outer fire pipe and internal fire pipe outer gap are unobstructed, and no dead angle in the Heat Room is difficult for depositing dirt.Pyrotechnics is taken out from fairlead by blower unit and is drawn, and the flame in the burner hearth is discharged by outer fire pipe, upper collecting chamber, internal fire pipe, next part case and fairlead below the bottom tube plate successively, thereby carries out heat exchange, the heat utilization efficiency height with water in the Heat Room.

The beneficial effects of the utility model are, compact conformation is made simply, and fire tube is arranged many, and heat exchange is abundant, and water jacket is unimpeded not to have the dead angle, solved prior art and existed and be easy to deposit dirt, the inadequate technical problem of heat exchange, and be a kind of desirable hot-water boiler pot body.
