Description

The tower type energy-conserving environment-protection boiler

Technical field

The utility model relates to a kind of tower type energy-conserving environment-protection boiler, belongs to the boiler technology field.

Background technology

Tower boiler kind in the market is a lot, and architectural difference is bigger.But, these boiler ubiquity some shortcomings: category-A boiler for example shown in Figure 1, straight fire tube and chimney all are straight up, heat emits and causes heat utilization ratio low, amount of dust is big, contaminated environment, simultaneously in the indoor chimney section of the overhead vapor of boiler owing to directly contact with steam, perishable impaired, the general life-span is about 8-14 month.Category-B boiler as shown in Figure 2, though solved the problem of chimney rapid wear, the thermal energy of straight fire tube disperses, chimney siphons away fire simultaneously, changed fiery direction, caused flue to be subjected to heating rate low, and stopped the residing position of fiery switch and can not reach the effect of stopping fire fully.

Summary of the invention

Technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of tower type energy-conserving environment-protection boiler is provided, and makes it have the combustion rate height, compare the fuel savings amount with similar boiler and reach more than 40%, smoke discharge amount is low, and the boiler cost is low, characteristics such as floor space is little, and is easy to maintenance.

The technical solution of the utility model is: it is made up of the flue in body of heater, flue, vaporium, external chimney, the body of heater, straight oblique fire tube, straight tiltedly water pipe, burner hearth.

Boiler bottom is a burner hearth, and the burner hearth front has a coal filling hole, and the bottom is slag notch and air inlet.Straight oblique fire tube runs through the flue that the water separation layer is communicated with burner hearth and flue below, wherein straight fire tube aligns the positive center, bottom of flue, one group of oblique fire tube is circle-shaped uniform ring around straight fire tube, the end that this group oblique fire tube connects flue and straight fire tube distance are less than being connected burner hearth one end and the distance of fire tube directly, thereby can be along straight fire tube and oblique fire tube rising by the flame of burner hearth generation, formation concentrates on the flame of flue bottom centre, can produce the heat of concentrating in the bottom of flue.Because one group of oblique fire tube is tilting, the flame that is produced by burner hearth can increase the contact area with fire tube during by fire tube, thereby has enlarged area heated, makes that the circulation water layer in the intercalated water sleeve can better absorb heat.

As further improvement of the utility model, be provided with intercalated water sleeve in the body of heater of this boiler, the recirculated water that is circulated in the whole cooker furnace interior is housed in the intercalated water sleeve, flue bottom links to each other around the recirculated water in the intercalated water sleeve around the cylinder water pipe at the oblique water pipe of its circumference and top and the body of heater by one group, and this oblique water pipe connects flue one end will be higher than connection body of heater intraformational bed water jacket one end.She Ji purpose is to compare with straight water pipe because the effect of air pressure can be avoided at the inner bubble that produces of this water pipe like this, and allow and be deposited on scale in the inner bag along the bottom of the intercalated water sleeve of this oblique water pipe around being discharged to, simultaneously since flame when arriving the flue bottom can to around disperse to enter flue around flue, so just can further heat this oblique water pipe, make heat utilization efficiency further improve.

Further, extend upward and the flue of vaporium below by being positioned at boiler is connected with the chimney of outside along the profile complications of flue around the flue of flue.The benefit of this inclined design is to strengthen the also sedimentation of favourable dust of area of being heated, and has reduced the discharge capacity of flue dust.

The utility model is compared with prior art following advantage:

1, by the heating surface of fire tube and part flue is improved to the heating surface on inclined-plane by the plane, increased the area that the water separation layer is heated, and increased the time that flue dust stops in flue, and improved the sedimentation that heat utilization efficiency helps dust simultaneously, accomplished energy-conserving and environment-protective.

2, be communicated with a plurality of water pipes that are positioned at flue in flue and the intercalated water sleeve, can further absorb heat, make the thermal efficiency further improve, can avoid simultaneously producing bubble in that this water pipe is inner, and allow the bottom that is deposited on scale in the inner bag intercalated water sleeve around being discharged to along this oblique water pipe because it is oblique water pipe.

3, this boiler is provided with two cleaning doors, so the cleaning dust is very convenient.

4, the speed of gas is fast on this boiler, the air pressure height, and service life is long, uses simple, easy to operate.

5, the design of this New-type boiler is a freedom from repairs, and the life-span is more than 5 years, and is longer than the life-span of general similar boiler 2-3.
