The technical proposal is as follows: the energy saving and exhaust reduction vertical boiler equipment comprises a boiler casing and a base seat, wherein, a furnace is arranged in the boiler casing, thereby the cost is low, a multifunctional fire brick with a vent hole channel is installed on the upper periphery of a hearth at the lower part of the furnace along a fire grate, and a functional air chamber is arranged at the lower part of the multifunctional fire brick. Compared with the prior art, the energy saving and exhaust reduction vertical boiler equipment has the advantages that a brand new combustion environment and power conditions are formed, the heat radiation is enhanced, the furnace temperature is increased, and the combustion reaction of coal is violent, the high efficiency combustion and the cleaning combustion are realized, the coal consumption and the slag drainage are reduced, and the chimney cannot generate black smoke; in addition, the structure is simple, the reconstruction is convenient, and the cost is low.

Description

A kind of energy-saving and emission-reduction vertical boiler equipment

Technical field

The utility model relates to combustion apparatus fields such as boiler, specifically belongs to a kind of novel energy-saving and emission-reduction boiler combustion equipment.

Background technology

Traditional vertical boiler thermal efficiency is low, and coal-fired waste is serious, over-emitting black exhaust, serious environment pollution.But it is little that it possesses rated power, and floor space is few, is convenient to advantages such as installation, is widely adopted with quantity of steam or the little unit of heating area at some.Though on project organization, occurred New-type boilers such as anti-burning stove in recent years, all can not fundamentally change the present situation of coal-fired waste and over-emitting black exhaust contaminated environment.

Summary of the invention

For overcoming deficiency of the prior art; the purpose of this utility model just provides a kind of vertical boiler with novel energy-saving and emission-reduction design; it can make the fuel-efficient burning, significantly improve the utilization rate of coal and the boiler operatiopn thermal efficiency; in the fuel-saving while; reduce the discharging of pollutant, help environmental protection.

For achieving the above object, the utility model adopts technical scheme to be: a kind of energy-saving and emission-reduction vertical boiler equipment, comprise shell and base, be provided with flue in the shell, described inwall upper periphery in the flue lower furnace, along fire grate the multi-functional refractory brick that has ventilating hole channel is installed, the bottom of described multi-functional refractory brick is provided with the function air compartment that is connected.

The ventilating hole channel of described multi-functional refractory brick is divided into horizontal duct and the vertical duct that is communicated with each other.

The top of described burner hearth is equipped with the high-energy radiation plate that is provided with exhaust gases passes.

Described high-energy radiation grillage is put plane on multi-functional refractory brick.

Described high-energy radiation plate is one or more composition.

Compared with prior art, the beneficial effects of the utility model are:

1, the utility model is on the basis that does not change former vertical boiler pressure parts its burner hearth partly to be transformed, and is therefore simple in structure, and it is convenient to transform, and cost is low.

2, adopt technical solutions of the utility model to transform and form a kind of brand-new burning situation and dynamic condition in the rear hearth, it has strengthened heat radiation, has improved furnace temperature, make the burning of coal reaction violent, realized efficient burning, clean combustion, coal consumption and bed drain purge reduce, and chimney is over-emitting black exhaust no longer.

Description of drawings

Accompanying drawing is that vertical energy-saving reduces discharging the boiler structure schematic diagram.

The 1-outlet pipe, 2-shell, 3-flue, 4-boiler tube, 5-high-energy radiation plate, the multi-functional refractory brick of 6-, 7-fire door, 8-shoot door, 9-fire grate, 10-air blast, 11-base, 12-function airduct, 13-function air compartment, 14-safety valve, 15-chimney, 16-burner hearth.

The specific embodiment

Also the utility model is described in further detail in conjunction with the accompanying drawings below by specific embodiment, and following embodiment is only used for explanation rather than restriction the utility model.

Referring to accompanying drawing, this use is novel to be on the basis that does not change former vertical boiler pressure parts its burner hearth partly to be transformed, and vertical boiler described in the utility model is made of shell 2 and base 11.Flue 3 is arranged in the shell 2, and the bottom is provided with burner hearth 16, and flue 3 tops are provided with boiler tube 4, boiler tube 4 is provided with outlet pipe 1, the top of shell 2 and flue 3 is provided with chimney 15 and safety valve 14, and the flue bottom is provided with fire grate 9, fire grate is for 9 times a base 11, be the flue cavity above, the outside, bottom at shell 2 and flue 3 is provided with fire door 7, be used to add fuel, base below arranged outside has shoot door 8.

At the inwall upper periphery of burner hearth 16, along fire grate 9 the multi-functional refractory brick 6 of a circle is installed, there are a plurality of eyelets on its surface, the duct that inside has horizontal and vertical intercommunication to be communicated with.It has the refractoriness height, the characteristics that compressive resistance is high.Below fire grate 9, be provided with function air compartment 13 along the below of multi-functional refractory brick 6, the following air inlet of function air compartment 13 links to each other with the air blast 10 of outside by function airduct 12.The last air outlet of function air compartment 13 is connected with the duct of multi-functional refractory brick 6 belows, air blast 10 blasts the function wind of function air compartment 13 by function airduct 12, be blown into the vertical duct import of multi-functional refractory brick bottom through the air port, top, from horizontal eyelet, blow to burner hearth again, enter the combustion zone, air blast primary air generation disturbance with fire grate is blown into for 9 times produces eddy current, thereby has optimized the burning condition of fuel.

Burner hearth 16 tops are provided with high-energy radiation plate 5, and described high-energy radiation 5 mounts on plane on the multi-functional refractory brick, and the high-energy radiation plate can divide several making, puts into burner hearth, form the cover plate of a circle at roof of the furnace.And high-energy radiation plate 5 leaves plurality of holes when making, as smoke flow channels.The effect of high-energy radiation plate 5 is to make the flue gas that produces after the fuel combustion, comprises that unburnt combustible rests in the burner hearth for a long time, has adequate time to be burnt repeatedly, until burnouting.Another effect is to form strong infrared source with all around multi-functional refractory brick, makes that burner hearth is inner to keep the condition of high temperature, thereby impels coal-fired violent burning.Coal through burning repeatedly after, the duct by the high-energy radiation plate enters chimney, row is to atmosphere.Do not contained unburnt carbon black particle and fuel gas in the flue gas this moment, becomes colourless flue gas, no longer atmosphere polluted.Simultaneously, coal reaches completing combustion, makes the part of original waste, has all been burnt, and changes into heat energy, thereby has reached effect of coal saving.
