CN2414070Y - Third air intaking glass kiln capable of eliminating black smoke - Google Patents

Abstract

The utility model relates to a third air intake glass kiln which can eliminate black smoke. The utility model comprises a heat exchange chamber a, a gas generator b, a small kiln c, a glass melting chamber d, a high temperature discharge gas passage 4 and a chimney. The third air intake glass kiln is characterized in that a third intake blast air inlet 1 and a preheating passage 2 are additionally arranged on the outer wall of the high temperature discharge gas passage, and a gas inlet passage is communicated with the high temperature discharge gas passage through a spraying inlet 3. Because the utility model adopts a third air preheating passage, third air is heated to be mixed with the discharge gas after enters the utility model, and the flow resistance of the discharge gas can not be increased; with the existence of the passage, the third air intake for preheating and dissipating the heat of the kiln is utilized, and the heat radiation quantity of the kiln is reduced; the effect of eliminating the black smoke is obvious; the utility model is suitable for reconstructing various coal burning glass kilns manually operated.

Description

Can eliminate three air intake glass furnaces of black smoke

The utility model relates to the improvement of glass furnace, particularly a kind of three air intake glass furnaces can eliminating the chimney over-emitting black exhaust.

At present, manually-operated coal-burning glass kiln since fuel cost low, adapt to coal wide, build advantages such as the stove investment is little and still generally adopted.In decades, manually-operated coal-burning glass kiln adopts the secondary air combustion supporting technology always, environmental protection and energy-conservation aspect obtained significant progress; But, when coal or removing lime-ash, pyrotechnics amount when soft coal contacts red charcoal increases severely, and substantially constant and limited secondary air flow can't be given birth to perfect combustion with the pyrotechnics volume production of its increase this moment, combustiblesubstances such as carbon black in the imperfect combustion pyrotechnics and hydrocarbon polymer in atmosphere, cause the pollution of atmosphere and environment with smoke stack emission.So how manual operation and the cindery coal-burning glass kiln of removing eliminate the chimney over-emitting black exhaust is problem demanding prompt solution.At present, domestic common employing whirlwind and water curtain smoke abatement device, the former poor effect, the latter also exists cost high and can produce secondary pollution problem.

It is a kind of by promoting the perfect combustion of high-temp waste gas that the purpose of this utility model is to provide, and can eliminate three air intake glass furnaces of black smoke.

Above-mentioned purpose of the present utility model is to realize that by such technical scheme promptly a kind of three air intake glass furnaces can eliminating black smoke comprise Heat Room, producer gas generator, port, glass melting chamber, high-temp waste gas passage and chimney; It is characterized in that: set up three times at the exterior wall of high-temp waste gas passage and advance blast inlet and preheating channel thereof, and by entrance with air inlet and high-temp waste gas channel connection.

Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.

Accompanying drawing is the structural representation of the utility model embodiment.

Referring to accompanying drawing, the glass furnace among the figure is a tank furnace formula glass furnace, comprises Heat Room a, producer gas generator b, port c, glass molten pool d, high-temp waste gas passage 4 and chimney; It is characterized in that: set up tertiary air blast orifice 1 and air intake preheating channel 2 thereof at the exterior wall of high-temp waste gas passage, and air intake is communicated with high-temp waste gas passage 4 by entrance 3.

The above-mentioned tertiary air air intake preheating channel 2 and the position of entrance 3 are selected according to the difference of glass furnace type, for example, when the type side of the being stove of kiln or circular furnace, the preheating channel of its three air intakes and the position of entrance and tank furnace formula different, but all be arranged on the exterior wall of high-temp waste gas passage, and the position that import is arranged on be convenient to gas blower to be installed; The quantity of entrance 3 can be provided with a plurality of as required.

Working process of the present utility model is such: after realizing that tertiary air is introduced in air blast, in exhaust steam passage, produce a large amount of excess airs, with coal immediately or the combustible mass such as carbon black of the incomplete combustion that increases in the high-temp waste gas when removing lime-ash in the high-temp waste gas road of certain-length, mixes generation perfect combustion, thereby reach the elimination black smoke; Black smoke stops the tertiary air gas blower and gets final product after eliminating.By such repeatable operation, can guarantee no longer over-emitting black exhaust of chimney.

The characteristics that the utility model is following owing to said structure has:

1. owing to adopt the tertiary air preheating channel, after entering, mixes with waste gas again through heating tertiary air, Can not increase the resistance of exhaust-gas flow; The existence of passage had both utilized three air intakes of heat radiation preheating of kiln, Reduced again the heat dissipation capacity of kiln;

Simple in structure, be convenient to existing kiln is transformed;

3. the elimination effect of black smoke is obvious, helps environmental protection;

4. suitability is strong, is adapted to various manually-operated coal-burning glass kilns, as the transformation of circular furnace, square stove, tank furnace etc.

Claims (1)

1. three air intake glass furnaces can eliminating black smoke comprise Heat Room (a), producer gas generator (b), port (c), glass melting chamber (d), high-temp waste gas passage (4) and chimney; It is characterized in that: set up at the exterior wall of high-temp waste gas passage and advance blast inlet (1) and preheating channel (2) thereof for three times, and pass through entrance (3) air inlet and high-temp waste gas channel connection.
