Description

The full wet type structure central heating unit of external double-cut tube heat exchanger

The utility model relates to a kind of central heating unit, specifically is meant the central heating unit of the full wet type structure that is equipped with double-cut tube heat exchanger outside body.

A kind of central heating unit is arranged at present, and matchmaker's water of its body inner chamber participates in thermal cycle, and it can only heat supply, heating, and the health hot water of clean cleaning can not be provided.

The purpose of this utility model provide a kind of can not only heat supply, heating, the central heating unit of full wet type structure of the external double-cut tube heat exchanger of health hot water can also be provided.

Design of the present utility model is: it mainly is made up of body fuselage, combustor, flue, secondary furnace, smoke pipe, front smoke box, back smoke box, chimney, breather pipe, outlet pipe, double-cut tube heat exchanger, it is characterized in that two outlet pipes being installed in body fuselage inner chamber upper parallel, closed at both ends wherein, on pipe shaft, have blasthole, another root one end sealing, the other end stretches out body fuselage, be communicated with double-cut tube heat exchanger by connecting piece, two outlet pipes are communicated with by communicating pipe in body.

Below in conjunction with accompanying drawing the utility model is described in detail.

Embodiment:

Referring to Fig. 1-Fig. 7, the utility model is mainly by body fuselage (1), combustor (18), flue (16), secondary furnace (14), smoke pipe (23), front smoke box (22), back smoke pipe (24), chimney (7), breather pipe (5), outlet pipe (8), double-cut tube heat exchanger (11) is formed, it is characterized in that two outlet pipes (8) being installed in body fuselage (1) inner chamber upper parallel, closed at both ends wherein, on pipe shaft, have blasthole (28), another root one end sealing, the other end stretches out body fuselage (1), be communicated with double-cut tube heat exchanger (11) by connecting piece, two outlet pipes (8) are communicated with by communicating pipe (29) in body.

Referring to Fig. 1, the utility model in use, only need the body inner chamber is piled matchmaker's water, after the igniting, oil or gas pass through combustor (18) in flue (16) internal combustion, produce high-temperature gas, high-temperature gas (being flue gas) is by secondary furnace (14), enter front smoke box (22) through two return smoke pipe (23), smoke pipe (24) after three backhaul smoke pipes (23) enter, enter atmosphere by chimney (7), when high-temperature flue gas is passing through flue (16), secondary furnace (14), smoke pipe (23), front smoke box (22), during back smoke box (24), its heat is absorbed by matchmaker's water of body inner chamber, matchmaker's coolant-temperature gage raises rapidly, high temperature matchmaker liter waterborne, when water pump (9) starts, high temperature matchmaker water is through the blasthole (28) of the outlet pipe (8) of closed at both ends, communicating pipe (29), enter another outlet pipe (8), through filter (26), water pump (9), outlet pipe (25), enter in the double-cut tube heat exchanger (11), owing in the double-cut tube heat exchanger (11) baffle plate (31) is arranged, health hot water in the double corrugated pipe (30) is heated up rapidly again, through other end baffle plate (31) opening of double-cut tube heat exchanger (11), heating user backwater; Through water inlet pipe (13), enter the body inner chamber and continue to heat up.And user's low temperature backwater enters double corrugated pipe (30) through user's return pipe (12), backwater in the double corrugated pipe (30) is subjected to managing preheating of western medium's water, temperature rises, enter the double corrugated pipe (30) of high-temperature region from the other end of double-cut tube heat exchanger (11), the health hot water of high temperature is managed (10) to the user from water outlet and is exported to the user, matchmaker's water intensification that constantly circulates like this, heat double corrugated pipe (30) continuously, the hot water of double corrugated pipe (30) is constantly exported, and Shu Chu hot water is exactly health hot water like this.

The utility model makes it to provide the health hot water that meets sanitary standard because reasonable in design, compact conformation is installed double-cut tube heat exchanger (11) outside the body of full wet type structure central heating unit, and use suitable hotel, office building and public place of entertainment.
