The direct-fired gas producer has the advantages of safety, environmental protection, normal pressure operation, high heat efficiency and convenience for maintenance.

Description

Direct-fired gas generator

Affiliated technical field

The utility model relates to a kind of direct-fired gas generator, belongs to hot water stove and accessory technical field, and is a kind of specifically split type and can produce the novel energy-conserving hot water stove and accessory of hot water fast.

Background technology

The multiduty facility that the hot water stove and accessory is that a kind of collection that people generally use is heated up water, hot water is used in heating, bathing and industrial and agricultural production.Because the rise of coal price, will waste a large amount of energy every year, and exist shortcomings such as stove and accessory contaminated air, manufacturing maintenance trouble, cost of manufacture height.

The utility model content

The purpose of the utility model, be a kind of environmental protection of design, energy-efficient, heat up water fast, and can produce the water heater of coal gas.

The purpose of the utility model realizes through following technical scheme:

A kind of direct-fired gas generator; Form by relatively independent absorbed layer (3), vaporization layer (11), burning zone (12) three parts, it is characterized in that: be arranged in order between absorbed layer (3), vaporization layer (11), burning zone (12) three parts and be upper strata, middle level, lower floor;

Absorbed layer (3) is by the chimney that is positioned at the center (1), chimney water sleeve (2) and be positioned at outside the upper strata of absorbed layer (3) periphery water jacket (4) and upper strata fire tube (5) and form; Upper strata fire tube (5) passes the water jacket (4) outside the upper strata, is connected pipe (7) connection by water jacket bottom chimney water sleeve (2) bottom and the outer water jacket (4) in upper strata;

Vaporization layer (11) is made up of vaporization layer water jacket (8), middle level fire tube (10) and air intake opening (18), and middle level fire tube (10) vertically passes from vaporization layer water jacket (8), and air intake opening (18) is the passage that communicates with air;

Around the burning zone (12) is lower floor's water jacket (13), and the side of burning zone (12) is provided with lower furnace door (16);

The top of water jacket outside the upper strata (4) is connected water pipe (6) with the bottom of lower floor's water jacket (13) by levels and is communicated with, and the bottom of vaporization layer water jacket (8) is connected water pipe (17) with the top of lower floor's water jacket (13) by middle lower floor and is communicated with;

The top of absorbed layer (3) is provided with cold water inlet (20);

The upper side of vaporization layer (11) is respectively equipped with hot water outlet pipe (9), air gauge (19) and middle fire door (21);

The bottom of burning zone (12) is provided with blowoff valve (14) and slag-drip opening (15).

Owing to adopt said structure, the utlity model has safety, environmental protection, normal pressure operation, the thermal efficiency is high especially, and maintenance is remarkable advantage especially easily.

Air gauge (19); Cold water inlet (20); Middle fire door (21);

Vaporizing combustor (22).

The specific embodiment

Below in conjunction with accompanying drawing 1,2,3, the utility model is elaborated.

The coal-fired burner hearth internal combustion that drops into burning zone (lower floor) (12) through lower furnace door (16); But the redox reaction through complicacy produces coal gas; The vaporizing combustor (22) that flare and the flue gas that does not have a sufficient combustion get into vaporization layer (middle level) (11) through middle level fire tube (10) is vaporization combustion further, is provided with three layers of a plurality of air intake opening (18) around the vaporizing combustor (22), naturally the introducing air; Increased the oxygen-supplying amount of vaporizing combustor (22); Impel flue gas to burn more fully, firepower is more violent, and flue gas significantly reduces.At this moment, the inner space of heat fire tube (5) entering absorbed layer (upper strata) (3) along the upper strata, this space is the space between the water jacket (4) outside chimney water sleeve (2) and the upper strata, a spot of flue gas gets into chimney (1) in the bottom in space and is discharged in the atmosphere.

In the aforesaid operations process; The order of current is: cold water inlet (20)-→ chimney water sleeve (2)-→ water jacket connect pipe (7)-→ the outer water jacket (4) in upper strata-→ levels connect water pipe (6)-→ lower floor's water jacket (13)-→ middle lower floor connection water pipe (17)-→ vaporization layer water jacket (8)-→ hot water outlet pipe (9); The long flow path of current; The water jacket heating surface area is big, and inflow temperature also is to change high temperature over to from low temperature, and the thermal efficiency is high.

Because coal gas has passed through sufficient burning, so to airborne waste gas seldom from chimney (1) row, basic compliance with environmental protection requirements.

The middle fire door (21) of vaporization layer (middle level) (11) side is used for the convenient combustion case of observing, and is beneficial to cleaning and maintenance.

The blowoff valve (14) of burning zone (lower floor) (12) bottom is used for discharging the dirt of hot water, and slag-drip opening (15) is used for conveniently drawing out lime-ash.

Because the utility model is made up of relatively independent absorbed layer (3), vaporization layer (11), burning zone (12) three parts, so, when the needs overhaul, only need to take the connection water pipe between three parts apart, repair just very convenient.

In reality was made, if around burning zone (lower floor) (12), open several apertures, combustion case can be better, also can observe combustion case simultaneously, in time adds coal-fired.

In actual use, if connect an air-introduced machine at the end of chimney (1), energy-conservation situation also can further improve.
