Abstract

The invention relates to a heating furnace matching part using biomass particles as main fuel, namely a biomass heating furnace steam dust removal device. The furnace comprises a water jacket arranged in a furnace body, wherein a water inlet is arranged on the water jacket, and the water jacket is also connected with a nozzle arranged in a side flue. When the furnace is burnt, water in the water jacket is heated to generate steam which is naturally sprayed out from the nozzle, and the nozzle is arranged in the flue to realize dust fall. The heat in the furnace body is utilized to heat water to form steam, and the steam is introduced into the flue to be sprayed out, so that the dust fall is realized, and the dust-removing furnace has the characteristics of simple structure, practicability and environmental protection.

Description

Biomass heating furnace steam dust removal device

technical field

The invention relates to a supporting part of a heating furnace with biomass particles as the main fuel, that is, a steam dust removal device for a biomass heating furnace.

Background technique

In the prior art, there are many types of fuel furnaces that use plant fibers such as straw as raw materials to make biomass particles, and their structures are different. The biomass particle energy-saving heating furnace that the applicant applied for on the same day includes a furnace body with a water jacket, a furnace, a grate in the furnace body, and an upper water inlet and a water return inlet on the water jacket. There is a feeding hopper on the upper part of the furnace, and a feeder at the outlet of the lower part of the feeding hopper; there is a primary air inlet on the upper part of the furnace, and a secondary air inlet on the lower part of the furnace; there is a smoke passage surrounded by a water jacket and a chimney outlet on the side of the furnace. Its disadvantage is that there is no dust removal device in the smoke passage.

Contents of the invention

The object of the present invention is to provide a biomass heating furnace steam dust removal device with better dust removal effect in view of the above shortcomings.

The technical solution of the present invention is: the steam dedusting device of the biomass heating furnace includes a water jacket arranged in the furnace body, the water jacket has a water inlet, and the water jacket is also connected with a nozzle placed in the side flue. When the furnace is fired, the water in the water jacket is heated to generate steam, which is naturally ejected from the nozzle, and the nozzle is placed in the flue to achieve dust reduction.

The invention has the advantages of using the heat in the furnace to heat water to form steam, which is introduced into the flue and sprayed out to realize dust reduction, and has the characteristics of simple structure, practicality and environmental protection.

Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Description of drawings

Accompanying drawing is the structural diagram of the present invention.

Detailed ways

Referring to the accompanying drawings, the biomass heating furnace steam dedusting device includes an annular water jacket 17 arranged in the furnace body. There is a water inlet 16 on the water jacket 17. The water jacket 17 is also connected to a nozzle 18 placed in the side flue. The nozzle 18 Position is higher than water jacket 17. The position and shape of the spout 18 in the flue are not limited, and they can be arranged on one side of the flue or along the ring of the flue, so as to facilitate dust reduction. The names of the main parts of the biomass heating furnace are as follows: water jacket 1, water jacket 2, furnace 3, furnace grate 4, slag outlet 5, upper water outlet 6, return water outlet 7, feed hopper 8, feeder 9, primary air inlet 10. Secondary air inlet 11, smoke passage 12, chimney outlet 13. The device is not limited to use on this stove, and can also be used to reduce dust on biomass heating stoves of other structures.

Claims (1)

1. A biomass heating furnace steam dedusting device is characterized in that comprising a water jacket (17) arranged in the body of the heater, water inlet (16) is arranged on the water jacket (17), and the water jacket (17) is also connected with a Spout (18) in side flue.
