CN2288386Y - Gradually expansion type steam space vertical fuel-oil water heater - Google Patents

Abstract

The utility model relates to a vertical fuel-oil water heater of a gradual expansion type steam space, composed of a boiler cylinder, a U-shaped food ring, a burning chamber, a burning cylinder, a smoke pipe, a conical smoke channel, a gradual expansion type steam space, etc. The burning chamber is positioned on the lower part of the water heater, and is connected with the burning cylinder. The bottom of the burning chamber is a fireproofing material layer. The smoke channel is positioned in the water heater. The lower end of the smoke pipe is connected with the burning chamber, and the upper part of the smoke pipe is connected with the lower end of the conical smoke channel. The upper end of the conical smoke channel is connected with an upper sealing head. The gradual expansion type steam space in a boiler is formed between the conical smoke channel and the boiler cylinder. When steam passes through the gradual expansion type steam space, the flow speed is reduced, and the steam and the water are effectively separated. The water quantity in the atmospheric steam is greatly reduced.

Description

The vertical fuel oil hot water boiler of the gradual-enlargement type vapor space

The utility model relates to no pressure fuel oil hot water boiler.

The vertical no pressure fuel oil hot water boiler pattern of using is more at present, can be divided into single using and two kinds of patterns of three usefulness by its function.Single is hot water below 95 ℃ with only production temperature of type, for bathe with or heating, idle call.Outside the three usefulness type decapacitation hot-water supplies, still can produce the atmospheric steam that 100 ℃ of drinking waters and steamed rice are used.The two structural similarity, but be provided with the vapor space on the top of three purpose stove.

Capacity is 348.8KW (30 * 10 ⁴KCal/H) following no pressure fuel oil hot water boiler majority adopts vertical, fire-tube type.The vertical no pressure fuel oil hot water boiler of great majority three usefulness types is owing to structural reason, and top vapor space volume is less, and the atmospheric steam water amount of production is many, influences user's result of use.

The purpose of this utility model is to design a kind of novel vertical fuel oil hot water boiler of the gradual-enlargement type vapor space, and it is good, energy-conservation and environment protecting is good to have a security, and water amount is few in the steam.

The technical scheme that achieves the above object is to adopt the vertical cylinder body structure, and flue is conical flue.The utility model mainly is made up of drum, U-shaped pin circle, combustion chamber, combustion barrel, smoke pipe, conical flue, upper cover, the gradual-enlargement type vapor space.The combustion chamber is positioned at the water heater bottom and combustion barrel joins, and has constituted the radiation heating-surface of stove.Burner of the outer end attaching of combustion barrel, the flame that burner produces enters the combustion chamber by combustion barrel from horizontal direction.Constituted the convection heating surface of stove with many smoke pipes of combustion chamber vertical connection, the lower end and the combustion chamber of smoke pipe join, and the lower end of upper end and conical flue joins.The upper end of conical flue links to each other with upper cover.Constituted the gradual-enlargement type vapor space between conical flue and the drum, steam has reduced flow velocity during by the gradual-enlargement type vapor space, has carried out the carbonated drink separation effectively, makes that water amount greatly reduces in the atmospheric steam of production.

Wherein, in smoke pipe, also be provided with rotation shape flow deflector.

In addition, on water inlet pipe, be equipped with electric water treatment device.

The utility model has the advantages that:

1. because employing is columnar structured, and body of heater pressurized performance is good, security is good.

2. in flue, add rotation shape flow deflector, can strengthen heat exchange, reduce exhaust gas temperature, improve the thermal efficiency, obvious energy-saving effect is arranged.

3. constituted the gradual-enlargement type vapor space in pot between the conical flue on stove top and the drum.The steam that evaporating surface produces in the pot has reduced flow velocity by the gradual-enlargement type vapor space time, carried out the carbonated drink separation effectively, makes that water amount greatly reduces in the atmospheric steam of production.

4. on water inlet pipe, be equipped with electric water treatment device, energy scale removal, antiscale, saving operating cost, the service life of prolongation stove.

Accompanying drawing is a cross-sectional view of the present utility model.

Label is in the accompanying drawing:

1............ gland steam exhauster 9............ refractory masses

2............ gradual-enlargement type vapor space 10............. base

3............. conical flue 11..............U shape pin circle

4.............. drum 12................. combustion barrel

5............... smoke pipe 13................ hot water outlet pipe

6............... boiling water outlet pipe 14................ upper cover

7............... combustion chamber 15.............. blow-down pipe

8.............. water inlet pipe

Below in conjunction with accompanying drawing structure technology feature of the present utility model is described further, it must be noted that, present embodiment for illustrative purposes only, rather than to restriction of the present utility model.

See also shown in the accompanying drawing, the utility model mainly is made up of drum 4, U-shaped pin circle 11, combustion chamber 7, combustion barrel 12, smoke pipe 5, conical flue 3, upper cover 14, base 10, the gradual-enlargement type vapor space 2 etc.Combustion chamber 7 is positioned at the water heater bottom and combustion barrel 12 joins, and the bottom of combustion chamber 7 is the fire-resistant village bed of material 9.The lower end of many smoke pipes 5 and combustion chamber 7 join, and the lower end of upper end and conical flue 3 joins.The upper end of conical flue 3 links to each other with upper cover 14.Constitute the gradual-enlargement type vapor space 2 between conical flue 3 and the drum, in addition, on water inlet pipe, be equipped with electric water treatment device.

At oil burner of the outer end of combustion barrel 12 attaching, burner is provided with protective device during operation.Can auto extinguishing when lack of water and stove water overtemperature in stove, out of service.Flame and high-temperature flue gas that burner produces enter combustion chamber 7, and high-temperature flue gas 7 enters the conical flue 3 on water heater top by many smoke pipes 5 from the combustion chamber again.The upper end of conical flue 3 is connected with chimney, and the flue gas after cooling is finally discharged from chimney.Water heater is provided with thermostat, and during heat supply water, leaving water temperature can set up on their own, and the start and stop of suction pump and magnetic valve are all regulated automatically by temperature controller.Water temperature is lower than the leaving water temperature of setting in stove, and burner promptly starts operation, the water in the water heater from the combustion chamber 7 and the heat absorption of smoke pipe 5 outer walls form hot water.When the hot water temperature arrived the leaving water temperature of setting, burner was promptly out of service, and external magnetic valve and suction pump are opened in stove and drawn water on the hot water outlet pipe 13.After water level reduced in stove, external magnetic valve and supply-water pump were opened in stove and are supplied water until predetermined water level on the water inlet pipe 8.Because water inlet descends stove water water temperature, burner restarts stove water is heated up.During for boiling water, keep water temperature and water level automatically by temperature controller and fluid level controller.Can set the stove coolant-temperature gage earlier is boiled water temperature, when temperature in the stove arrives boiled water temperature, can emit boiling water from boiling water outlet pipe 6, from gland steam exhauster 1 atmospheric steam is connected to rice steaming box and uses, at this moment, still keep water level in the stove by magnetic valve external on the fluid level controller start and stop water inlet pipe 8 and supply-water pump.
