Abstract
The invention discloses a kind of full-heated type gas normal-pressure water heaters.The full-heated type gas normal-pressure water heater includes burner (1), combustion chamber (2), the smoke box being connected with combustion chamber combines (3), smoke box combination is placed in hot-water cylinder (4), hot-water cylinder top and packed tower (10) connection.The full-heated type gas normal-pressure hot water kiln gas by exchanging heat three times: primary heat exchange, and by water pipe (26) and smoke pipe (20) in smoke box combination (3), temperature is lowered the high-temperature flue gas for generation of burning；Secondary heat exchange is directly contacted with the water at low temperature that packed tower (10) top sprays on filler (9) surface after the flue gas come out from smoke pipe (20) enters packed tower (10), realizes heat transfer, mass transfer；It exchanges heat three times, flue gas is last to be cooled down by the air in economizer bank group (15) again again, combustion air of the air being heated as burner (1).Heating furnace structure is compact, and thermal energy is fully used.
Description
Technical field
The present invention relates to boiler plant technical fields, and in particular to full-heated type gas normal-pressure water heater.
Background technique
In existing full-heated type gas normal-pressure water heater production process, since high-temperature flue gas is directly contacted with water, there are fire
Flame hardening phenomenon is easy to produce the harmful substances such as ethyl alcohol, acetaldehyde, formic acid, carbon monoxide.
The fire tube top of full-heated type gas normal-pressure water heater, is not submerged by water that portion temperature is higher, causes the material of the position
Expect that pernicious variation occurs for metallographic structure, makes equipment cisco unity malfunction.
Summary of the invention
The object of the present invention is to provide a kind of energy-efficient, the gas normal-pressure water heaters of energy long period safe operation.
Present invention technical solution used for the above purpose is:
A kind of full-heated type gas normal-pressure water heater, including burner, combustion chamber, the smoke box being connected with combustion chamber combine, cigarette
Case combination is placed in hot-water cylinder, and hot-water cylinder top is connected with packed tower.
On the tank skin of the hot-water cylinder, overflow port is being set lower than smoke pipe top flue gas outlet port.
On the tank body of the hot-water cylinder, it is provided with hot water outlet, sewage draining exit.
Smoke box combination is internal to be arranged water pipe, and smoke box combines upper perforated plate and connects smoke pipe, the water pipe both ends respectively with it is upper
Tube sheet is connected with lower perforated plate.
Exhanst gas outlet, water retaining cover is arranged in the top of the smoke pipe.
The filler tower bottom is provided with orifice plate, and filler is banked up on orifice plate, and filler is sequentially arranged above spray equipment, air
Economizer bank group, flue.
The spray equipment is made of one group of nozzle being mounted on concetrated pipe.
The economizer bank group is made of air inlet filter, economizer bank, collecting box, air outlet slit.
Water jacket is provided with outside the combustion chamber.
The beneficial effects of the present invention are:
Flue gas by exchanging heat three times, and heat is fully absorbed, and heating furnace structure is compact.
The high-temperature flue gas of primary heat exchange, generation of burning passes through the water pipe inside smoke box combination and the smoke pipe connecting with upper perforated plate
Afterwards, temperature is lowered, and avoids flame hardening phenomenon, and the metal on smoke pipe top is protected not to be destroyed.
Secondary heat exchange, after the flue gas come out from smoke pipe enters packed tower, the water at low temperature sprayed with packed tower top exists
Filler surface directly contacts, and realizes heat transfer, mass transfer, and packing specific area is big, and heat transfer efficiency is high, and the vapor in flue gas is condensed into
Liquid water releases latent heat, and heat utilization rate is high, and heat-energy losses are few.
It exchanges heat three times, flue gas is last to be cooled down by the air in economizer bank again again, and the air being heated is as burning
The combustion air of device, thermal energy are fully used.

Specific embodiment
As shown in Fig. 1, the present invention combines (3), water pot (4), packed tower (5) by burner (1), combustion chamber (2), smoke box
Composition.
Smoke box combination (3) is placed in water pot (4), and the upper perforated plate (23) that smoke box combines (3) connects smoke pipe (20), smoke pipe (20)
Top is provided with exhanst gas outlet (6), water retaining cover (7).
Water pot (4) bonding pad tower (10).
Abacus (8) are arranged in packed tower (10) bottom, stack filler (9) on orifice plate (8), and filler (9) is sequentially arranged above
There are spray equipment (19), economizer bank group (15), flue (16).
When work, the flue gas that burner (1) generates enters smoke box combination (3), by water pipe (26) and smoke pipe (20) outside
Enter in packed tower (10) after water is cooling, pass through filler (9), is arranged after being cooled down again by economizer bank group (15) by flue (16)
Out, meanwhile, the water sprayed in spray equipment (19) also enters in packed tower (10) from top, on filler (9) surface, flue gas and water
It sufficiently directly contacts, completes heat transfer, mass transfer.Water, which is heated to, needs temperature, and into water pot (4), flue gas after cooling down three times
Temperature can be reduced to the dew point of vapor contained therein hereinafter, vapor is condensed into water, releases latent heat.
When work, hot water is exported by hot water outlet (22) in water pot (4), and cold water enters spray equipment (19) return and fills out
Expect to be heated again in tower (10).Overflow port (5) controls the water level in hot-water cylinder, and hot water is avoided to flow into smoke pipe (20).
