Description

Full wet type structure central heating unit

The utility model relates to a kind of heating plant, specifically is meant a kind of central heating unit of the full wet type structure with fuel oil or combustion gas.

As central heating equipment, hot-water boiler, steam boiler are arranged at present, these equipment exist that one-time investment is big, floor space is many, and the thermal efficiency is low, and band is pressed operation, and the installation site requires harsh, the high shortcoming of administrative expenses.

It is little that the purpose of this utility model provides a kind of volume, and space availability ratio and thermal efficiency height move under normal pressure, the central heating unit of the unrestricted full wet type structure in installation site.

Design of the present utility model is, this mainly is made up of body fuselage, combustor, flue, back smoke box, two return smoke pipe, front smoke box, three backhaul smoke pipes, chimney, water inlet pipe, outlet pipe, breather pipe, from bottom to top be equipped with flue at square body fuselage inner chamber, flue one end install combustion machine, the flue other end communicates with the back smoke box, back smoke box is communicated with by the two return smoke pipe with front smoke box, and front smoke box is communicated with by three backhaul smoke pipes with chimney, is separated by dividing plate between back smoke box and chimney.There is a water inlet pipe insertion machine intracoelomic cavity body upper end, in body inner chamber top outlet pipe is housed, and the outlet pipe mouth of pipe extends body fuselage, in the body fuselage upper end breather pipe is housed and is communicated with the body inner chamber.

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

Fig. 1 is the generalized section of the utility model front view;

Fig. 2 is the A-A generalized section in Fig. 1 body fuselage;

Fig. 3 is the B-B generalized section in Fig. 1 body fuselage.

Embodiment:

Alleged " the full wet type structure " of the utility model is meant that the high-temperature flue gas that fuel produces carries out in the process of heat exchange in unit when burning, because heat-exchange device is surrounded by matchmaker's water, this external surface of unit does not contact with high-temperature flue gas.

Referring to Fig. 1-Fig. 3, the utility model is mainly by body fuselage (1), combustor (20), flue (12), back smoke box (13), two return smoke pipe (16), front smoke box (25), three backhaul smoke pipes (10), chimney (7), water inlet pipe (6), outlet pipe (9), breather pipe (4) is formed, promptly in square body fuselage (1) inner chamber (26), from bottom to top be equipped with horizontal flue (12), flue (12) one end install combustion machines (20), flue (12) other end communicates with vertical back smoke box (13), back smoke box (13) is communicated with by horizontal two return smoke pipe (16) with front smoke box (25), front smoke box (25) is communicated with by horizontal three backhaul smoke pipes (10) with chimney (7), is separated by dividing plate (11) between vertical back smoke box (13) and chimney (7).There is the vertical insertion machine intracoelomic cavity (26) of a water inlet pipe (6) the body upper end, and connection " ㄇ " shape pipe (17), the both ends of the surface sealing of " ㄇ " shape pipe (17), on " ㄇ " shape pipe (17), have inlet opening (27), in body inner chamber (26) top horizontal outlet pipe (9) is housed, outlet pipe (9) is in the end face sealing of body inner chamber (26), the end is supported by support (5), the outer wall of the other end of support (5) and front smoke box (25) is affixed, outlet pipe (9) mouth of pipe extends body fuselage (1), on the tube wall of the outlet pipe (9) of body inner chamber (26), have apopore (3), in body fuselage (1) upper end breather pipe (4) is housed, and is communicated with body inner chamber (26).

The utility model is when utilization and operation, discharge water into body inner chamber (26) from water inlet pipe (6), after the igniting, oil or gas pass through combustor (20) in flue (12) internal combustion, produce high-temperature gas, high-temperature gas (being flue gas) enters front smoke box (25) by back smoke box (13) through two return smoke pipe (16), enters atmosphere again after three backhaul smoke pipes (10) enter chimney (7).When high-temperature flue gas by flue (12), back smoke box (13), two return smoke pipe (16), front smoke box (25), three backhaul smoke pipes (10), chimney (7) time, its heat is absorbed by matchmaker's water of body inner chamber (26), matchmaker's coolant-temperature gage raises rapidly, high humidity matchmaker liter waterborne, extraneous water is by the constantly water outlet of inlet opening (27) of " ㄇ " shape pipe of the bottom of water inlet pipe (6), so continuous circulation provides high-temperature-hot-water from apopore (3) continually to outlet pipe (9).

The utility model has been owing to created the full wet type structure, its modern design, and compact conformation has increased heat exchange area to greatest extent, has reduced the body surface temperature, has improved the thermal efficiency widely, is the ideal equipment of heat supply heating.
