Abstract

The invention discloses a four-level air inlet system for a biomass briquette tobacco curing stove, belongs to the field of air inlet systems of stoves, and solves the problem that the atmosphere is polluted due to single air inlet. Biomass fuel can be efficiently combusted and utilized. The four-level air inlet system mainly comprises an air distribution tube, an upper air inlet tube and a lower air inlet tube, wherein one end of the air distribution tube (2) is a fan interface, and the other end of the air distribution tube (2) communicates with the upper air inlet tube (1), a middle air inlet tube (3) and the lower air inlet tube (4) through connecting surfaces; four lower air outlet tubes (5) are inserted at four corners of a lower air distribution channel (6) in an inclined straight manner; and a low fire blastpipe interface (8) and a lower air inlet tube interface (7) are formed in the upper part of a right side tube of the n-shaped lower air distribution channel. The four-level air inlet system is applicable to an air supply system of stoves.

Description

Biomass molding fuel flue-cured tobacco stove level Four air inlet system

Technical field

The invention belongs to stove field, be a kind of biomass molding fuel flue-cured tobacco stove level Four air inlet system.

Background technology

With wideling popularize of national energy-saving environmental protection policy regulation, biomass furnace will be gradually in a lot of industries Replace coal stove.Main cause is, coal can produce a large amount of dust and harmful gas when burning, acid Gas can form Acid rain damages environment.Compared with coal, biomass are a kind of clean energy resourcies, and burning is abundant, Pollutant emission is relatively low, is fully able to reach, with less than the relevant discharge standard of country, not to destroy environment.

The level Four air-intake device of this air inlet system, the fugitive constituent being built upon biomass molding fuel is bigger, General stove oxygen supply is insufficient, it is impossible to burn, the imflammable gas that fuel combustion produces in order to change completely The combustion efficiency of stove, the maximized utilization of imflammable gas produced during by burning, reduction fuel consumption, Improve on the basis of heat utilization rate, attempted by long-term technology repeatedly and research, proposition special Design.

Summary of the invention

Present invention aim to overcome that above-mentioned deficiency, propose a kind of biomass molding fuel flue-cured tobacco stove level Four and enter Wind system.

To achieve these goals, present invention employs techniques below scheme: this air inlet system by a point airduct, Upper blast pipe, lower blast pipe are constituted；Dividing airduct one end is fan interface, and the other end logical junction respectively is with upper Blast pipe, middle blast pipe, lower blast pipe are connected, and lower discharge pipe becomes four oblique straight states to be plugged in down a point air channel Corner at, above the right side pipe in lower point of air channel of n font, have low baking temperature blast pipe interface, lower blast pipe connects Mouthful.

Described upper blast pipe is made up of, such as two L-shaped three transverse tubes, two vertical tubes, three elbows, a junction Butt joint body；The end of upper blast pipe has multiple aperture.

Described middle blast pipe is a L-shaped state, and one end is connected with a point airduct by junction and straight tube, the other end and The most curved shape body is connected.

Described point of airduct is a T-shaped state, has a junction to connect with lower blast pipe, T-shaped top on the left of it It is respectively turned on upper blast pipe and middle blast pipe with two tubes, two junctions.

Four air-intake devices of air inlet system are that upper, middle and lower air feed is combustion-supporting and fire-retardant four air feeds of wind screen, Biomass molding fuel can be fully burned and use and pass through long period of experiments, research basis it Upper design invention, burner hearth fuel, imflammable gas can be made fully to burn, reduce discharge pollutants dense Degree, combustion heat energy is effectively utilized, and has reached again national requirements, efficient, energy-conservation, the standard of reduction of discharging.

Accompanying drawing explanation

Fig. 1 be the present invention connect structure schematic diagram.

Fig. 2 is that the lower point of air channel of the present invention connects composition.

In figure: upper blast pipe (1), point airduct (2), middle blast pipe (3), lower blast pipe (4), under go out Airduct (5), divide air channel (6), lower blast pipe interface (7), low baking temperature blast pipe interface (8) down.

Detailed description of the invention:

The embodiment of the present invention: point airduct (2) one end is fan interface, the other end logical junction respectively is with enterprising Airduct (1), middle blast pipe (3), lower blast pipe (4) are connected, and lower discharge pipe (5) becomes four oblique straight State is plugged in down at the corner in point air channel (6), above the right side pipe in lower point of air channel of n font, has low baking temperature drum Duct collar (8), lower blast pipe interface (7).

Described upper blast pipe (1) is made up of, such as two three transverse tubes, two vertical tubes, three elbows, a junction The butt joint body of L-shaped；The end of upper blast pipe (1) has multiple aperture.

Described middle blast pipe (3) is a L-shaped state, and one end is connected with a point airduct (2) with straight tube by junction, The other end is connected with the most curved shape body.

Described point of airduct (2) is a T-shaped state, has a junction to connect with lower blast pipe on the left of it, T-shaped Top and two tubes, two junctions be respectively turned on upper blast pipe (1) and middle blast pipe (3).It is available for stove Tool air feed system uses.
