Abstract

The utility model relates to a fast energy-saving boiler. The utility model is characterized in that the utility model adopts boiler pipes whose the diameter of pipe openings are bigger, the boiler pipes are directly welded on a boiler cylinder, the boiler pipes which are alternatively arranged in the boiler cylinder which is connected with the boiler pipes into one body are level with the outer margin of the boiler, cylinder, the boiler pipes are communicated with an outer cylinder, an upper drum, a lower drum and a jacket between an inner cylinder and an outer cylinder of residual heat, the outer cylinder of residual heat is also provided with a spraying water washing device and a dust removing drain pipe, and a drain pipe which is used for cleaning boiler scale is arranged under the outer cylinder. The utility model can burn boiled water 500 kg and hot water 200 kg with 8 kg coal consumption. The utility model has the advantages of fast energy saving, simple structure and easy manufacture. The utility model can be used as life boilers in institutions, schools and countryside and steam boilers in factories. The utility model can be applied to common machine factories or boiler factories.

Description

A kind of fast energy-saving boiler

The utility model relates to a kind of improvement of boiler for domestic, and particularly a kind of fast energy-saving boiler is suitable for office, school, boiler for domestic is made in the rural area and factory makes steam boiler.

The arrangement of existing vertical boiler for domestic boiler tube all is direct barrel type or the coiled that a direction is arranged, and the less high-temperature flue gas that makes of caliber directly passes through from straight tube or coil pipe gap, make water-filled boiler tube not have the process of abundant heat absorption and cause a large amount of heat energy dissipations, cause energy waste, prolong and heat up water the time, boiler cleans also inconvenient.

The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art part, has designed a kind of fast energy-saving boiler that can effectively overcome above-mentioned shortcoming.

The purpose of this utility model is such realization: upper drum and lower drum and the weldering of outer jacket casing are one, the waste heat apparatus of being made up of waste heat urceolus and waste heat inner core is housed on the urceolus tube edge, in upper and lower drum and waste heat inner core, all disposes staggered, boiler tube, boiler tube and communicate with chuck between urceolus and upper and lower drum and waste heat inner/outer tube with the concordant big caliber of the outer rim of cylindrical shell.

The bell shape hydroblasting device of doing dedusting is housed on the waste heat urceolus.

Urceolus is equipped with blow-off pipe down and on the hydroblasting device.

After adding coal combustion in the combustion chamber, the flue gas of temperature flowing contacts with chuck with water-filled boiler tube, and constantly mobile high temperature gas flow is tortuous to be contacted with pipe, cover, makes it fully absorb heat, thereby realizes quick, purpose of energy saving.Through testing: dress water 200kg in dress water 500kg, the waste heat tube in upper and lower drum water pipe, draw burning, normal combustion with coal (coal calorific value by 5000-5500 kilocalorie/time) 8kg from the coal of lighting a fire, after half an hour, the water of 500kg is promptly to boiling point, and the water temperature of 200kg reaches (inflow temperature is 18 ℃) about 80 ℃.The utility model also has simple in structure, easy to manufacture, advantages such as boiler cleaning, good dedusting effect.

Below in conjunction with accompanying drawing in detail the utility model structure is described in detail.

Fig. 1 is the utility model structure diagram.

Fig. 2 is Figure 1A-A cutaway view.

Fig. 3 is Figure 1B-B cutaway view.

Fig. 4 is Fig. 1 C-C cutaway view.

Fig. 5 is Fig. 1 D-D cutaway view.

Fig. 6 is Fig. 1 E-E cutaway view.

Referring to Fig. 1-Fig. 6, adopt segmentation to make welded seal and connect into holistic tower boiler.All directly welding the staggered many piece boiler tubes 19 concordant (the boiler tube diameter is bigger than existing shape caliber, as adopting the 100-150mm caliber) on upper drum 4, lower drum 2 and the waste heat inner core 9 with the outer rim of cylindrical shell (4,2,9).Upper drum 4 and lower drum 2 are welded into one with urceolus 3 covers and form a chuck 18, and each boiler tube 19 communicates with chuck 18.(bolt that adds sealing ring connects) is installed on 3 edge of urceolus goes up the waste heat apparatus of forming by waste heat inner core 9 and waste heat urceolus 10.On waste heat urceolus 10, be welded with bell shape hydroblasting device 14 (this device is used as getting rid of flue dust), it is provided with barrel-type casing outward, housing has dedusting blow-off pipe 11, the hemispherical water body of ejection can make the flue dust cleaning of chimney 12 bottoms from then on manage 11 discharges.The flue gas that last chimney 12 is discharged is white in color, to reach dust emission standard.Also be provided with the blow-off pipe 1 that cleans incrustation scale into boiler in the urceolus bottom.Because of boiler tube 19 calibers that adopted are thicker, so the incrustation scale in it also is easy to clean.In addition the utility model boiler also is provided with automatical pouring appliance 16 and heat water valve 6, heat control valve 5, fire door 17 etc., and safety attachments such as Pressure gauge 7, safety valve 8, water level meter 15, thermometer 13, necessary external pipe.Also be provided with the wind turning plate door of automatic unlatching in the chimney 12.Prior art is adopted in the combustion chamber.When being full of water in boiler tube 19 and the chuck 18 behind the last full running water, coal igniting manufacture hot water, boiling water and steam then.

The utility model product design size, external diameter: 600-1500mm, height: 2800-4200mm can optionally make boiling water or the steam boiler of 0.1-1T.
