Abstract

The invention discloses an automatic dust removal all-in-one machine of a biomass boiler. The all-in-one machine comprises a boiler and a dust collector, wherein a main body of the dust collector is a smoke chamber, the interior of the smoke chamber is provided with a smoke passage and a water cavity, the smoke passage is positioned in the middle part of the smoke chamber, the water cavity is arranged around the smoke passage, a smoke pipe is connected between a smoke outlet of the boiler and a smoke inlet of the dust collector, an outlet of the smoke pipe is provided with a cyclone blade, a hot water pipe is connected between a water inlet of the boiler and a water outlet of the dust collector, and a steam outlet of the water cavity is aligned with the cyclone blade. The all-in-one machine has the advantages that the structure is compact, and the manufacturing cost is low; because of the dust removal by the cyclone blade in the dust collector and the dust removal by the spraying of the steam outlet, the double dust removal effect is good, and clean exhaust is realized; in addition, the heated hot water in the water cavity is sent into the boiler by a water pump as feeding water into the boiler, the water feeding temperature is raised, and the water in the water cavity is heated by the smoke, so the smoke exhaust temperature is reduced, and heat efficiency of the boiler is effectively improved.

Description

The autonomous dust removing integrated machine of biomass boiler

Technical field

Patent of the present invention belongs to boiler technology field, specifically a kind of boiler all-in-one with self-service dedusting function.

Background technology

Because biomass fuel density is little, loosely organized, do not burn dust during burning easily to blow afloat, parcel coke granule, in addition air penetration difficulty, biomass fuel combustion is slow, difficulty burns, therefore dust is very easily taken away with boiler smoke, contaminated environment, so the flue gas of biomass boiler will just to airborne release after dedusting.The cleaner of biomass fuel boiler adopts cyclone dust collectors and sack cleaner usually, and there is floor space large, sack cleaner troublesome maintenance, cloth bag will often be changed and change the defects such as labour intensity is large.

Summary of the invention

In order to solve prior art Problems existing, the invention provides a kind of boiler all-in-one with self-service dedusting function.

In order to realize above object, the technical scheme that the present invention takes is: the autonomous dust removing integrated machine of a kind of biomass boiler, comprise boiler and deduster, the main body of described deduster is smoke chamber, gas flue and water cavity are set in smoke chamber, gas flue is positioned in the middle part of smoke chamber, and the surrounding of gas flue arranges water cavity;

Be connected fume pipe between the exhanst gas outlet of described boiler and the smoke inlet of deduster and cyclone blade is set in fume pipe exit, between the water inlet of boiler and the delivery port of deduster, being connected hot-water line;

The steam (vapor) outlet of described water cavity aims at cyclone blade.

Compared with prior art, present invention achieves biomass fuel boiler and deduster installation integration, compact conformation, low cost of manufacture.The cyclone blade dedusting of deduster inside and steam (vapor) outlet winding-up dedusting, double dust collection mode is effective, reach clean emission, and, boiler is delivered to as boiler feedwater by the hot water heated by water pump in water cavity, improve feed temperature, the water in addition in flue gas water cavity makes exhaust gas temperature reduce, and all effectively improves boiler thermal output.

Accompanying drawing explanation

Fig. 1 is the structural representation of the autonomous dust removing integrated machine of biomass boiler.

Detailed description of the invention

As shown in Figure 1, the autonomous dust removing integrated machine of biomass boiler, comprises boiler 1 and deduster 2.The main body of deduster 2 is smoke chamber 3, and arrange gas flue 4 and water cavity 5 in smoke chamber 3, gas flue 4 is positioned at the middle part of smoke chamber 3, and the surrounding of gas flue 4 arranges water cavity 5.Be connected fume pipe 6 between the exhanst gas outlet of boiler 1 and the smoke inlet of deduster and in fume pipe exit, cyclone blade 7 be set for dedusting.The steam (vapor) outlet of water cavity 5 connects steam pipe 8, and steam pipe 8 exports aims at cyclone leaf 7, utilizes steam blast dedusting.Hot-water line 9 is connected between the water inlet of boiler 1 and the delivery port of deduster.

Biomass fuel boiler flue gas enters deduster, through cyclone blade dedusting, and the water simultaneously in flue gas water cavity, the steam produced sprays into smoke chamber dedusting from top, flue dust is discharged from bottom, and flue gas enters middle gas flue and upwards flows after dedusting, drains at top.

Claims (1)

1. the autonomous dust removing integrated machine of biomass boiler, comprises boiler, it is characterized in that: also comprise deduster, and the main body of described deduster is smoke chamber, arranges gas flue and water cavity in smoke chamber, and gas flue is positioned in the middle part of smoke chamber, and the surrounding of gas flue arranges water cavity;
