Description
Technical field
The utility model belongs to expansion furnace field, specifically, relate to bottom discharge perforate furnace for expanding perlite.
Background technology
As shown in figure 1, traditional perforate furnace for expanding perlite discharging direction be from expansion furnace lower expansion open after by cooling
Blower fan behind water tank upwards draws the perlite after expansion from burner hearth 1-1, after cooling water tank 1-4 cooling, from water tank
Discharge nozzle 1-2 enters subordinate's cyclone separator.From structure chart as can be seen that lower husky mouth 1-6 be located at middle and lower part, ore in sand form be therefrom under
Portion enters expansion furnace, because the proportion of ore in sand form is larger, in order to ensure ore in sand form is unexpanded open before will not fall on bottom, connect
Must just there are enough air quantity to ensure that ore in sand form can suspend in water tank discharge nozzle 1-2 blower fan, so from expansion furnace bottom
A large amount of cold wind of suction fall the burner 1-3 valuable heat energy sprayed to dilution.And also due to fan delivery is too big, waste heat
Heat exchanger time is extremely short in preheating furnace, and a large amount of waste heats are still drained in vain, and one ton of perlite is expanded in theory and only needs to 30
Many cubes of natural gas, actual natural gas air consumption has reached 140-150 cubes per ton, and heat utilization rate is extremely low.Due to natural gas
It is the high-quality energy, on the premise of the still useful coal gas in market does the expansion furnace energy, perforate perlite is made of natural gas just complete
Lose competitiveness entirely.And the strict demand with country to environmental protection equipment, most of coal gas expansion furnaces are on the verge of being replaced, because
A kind of this research and development of new expansion furnace is extremely urgent.
In addition, existing perforate furnace for expanding perlite length is mostly close to 9m, required space is big, and to carry out insulation,
In burner hearth 1-1 outer wrapping refractory brick 1-5, to ensure the temperature requirement of natural gas, it is necessary to which natural gas preheating furnace is done into lengthening processing.
In order to solve the problem of above is present, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of this utility model is that there is provided a kind of design science, reduction energy consumption, simplified knot in view of the shortcomings of the prior art
Structure, the bottom discharge perforate furnace for expanding perlite for reducing volume.
To achieve these goals, the technical scheme that the utility model is used is：Bottom discharge perforate furnace for expanding perlite,
Including burner hearth, it is arranged at the burner of the burner hearth inside upper part, the lower husky mouth above the burner and is arranged at the stove
The blanking cone of thorax lower end, the blanking cone lower section is installed by the feed pipe of the connection blanking cone, one end connection of the feed pipe
One deflection cone is installed, the taper air outlet correspondence blanking cone of the deflection cone is set in pressure fan, the feed pipe.
Described on base, the taper air outlet of the deflection cone just bores the centrally disposed of direction that discharge to the blanking.
Described on base, the furnace height is 5-6m.
Described on base, the feed pipe tilts upward setting from feed end to discharge end.
Described on base, the burner hearth upper end connects waste heat introduction pipe, waste heat introduction pipe and the air-introduced machine connection.
Described on base, the internal diameter that expansion area at the burner is installed in the burner hearth is more than other positions in the burner hearth
Internal diameter.
Described on base, the chamber structure includes high temperature resistant stainless steel body and is arranged on the high temperature resistant stainless steel body
The rock wool heat-preservation layer in outside.
The utility model has substantive distinguishing features and progress compared with the prior art, specifically, with advantages below：
1st, perlite particle passes through whole burner hearth from top to bottom, and most of perlite can fall in self gravitation effect
Under, it is not necessary to extra that wind-force is injected into burner hearth, guiding perlite particle is sent out, it is ensured that heat energy makes full use of.
2nd, for solve smaller particle perlite due to hot gas ascending motion be difficult to fall the problem of, in feed pipe install
Pressure fan and deflection cone, thus in freeze profile into subnormal ambient, and only have the air of burner feeding in burner hearth, in suction function
Under, flare not on alter, the perlite of smaller particle also can smoothly fall.
3rd, furnace height is reduced to 5-6m by original 9m, saves installing space.
4th, furnace binding is simple, and inner bag uses high temperature resistant stainless steel, and heat-insulation layer is done in outside with rock wool, without refractory brick, whole
Cover body of heater and all manufacture completion in factory, weight is reduced to less than 2 tons from original more than ten tons, can significantly shorten installation period.
5th, the structure is not required to cooling water tank and blanking whirlwind, can save complete equipment cost；Preheating furnace need not do big
Change, change burner.

Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Fig. 2 the present embodiment offer bottom discharge perforate furnace for expanding perlite, bottom discharge perforate furnace for expanding perlite,
Including burner hearth 2-1, it is arranged at the burner 2-2 of the burner hearth 2-1 inside upper parts, the lower husky mouth 2-3 above the burner 2-2
2-4 is bored with the blanking for being arranged at the burner hearth 2-1 lower ends, the burner hearth 2-1 is highly 5-6m, pacified below the blanking cone 2-4
The feed pipe 2-5, the feed pipe 2-5 that the blanking cone 2-4 is led in load tilt upward setting from feed end to discharge end.It is described
A deflection cone 2-7, the cone of the deflection cone 2-7 are installed in feed pipe 2-5 one end connection pressure fan 2-6, the feed pipe 2-5
Shape air outlet just bores the centrally disposed of 2-4 dischargings direction to the blanking.Installed in the burner hearth 2-1 swollen at the burner 2-2
The internal diameter in swollen region is more than the internal diameter of other positions in the burner hearth 2-1.The burner hearth 2-1 structures include high temperature resistant stainless steel pipe
Body and the rock wool heat-preservation layer 2-8 being arranged on the outside of the high temperature resistant stainless steel body.
Because burner 2-2 is located at the middle and upper part of expansion furnace, lower husky mouth 2-3 is above burner 2-2, when burner 2-2 burns,
Hot-air can be moved upwards, if so expansion furnace bottom does not have air inducing, the smaller perlite expanded of particle falls certainly
Do not go down, to solve this problem, one deflection cone 2-7 of Position Design at 2-4 centers bored in feed pipe 2-5 against blanking,
Will so form certain negative pressure in expansion furnace when pressure fan 2-6 works, flare will not on alter, upper flame location dimension is held
In the position more slightly higher than burner 2-2, so that ensureing the expanded perlite of variable grain can fall, except burner in expansion furnace
The gas discharged after burning, enters without any unnecessary cold air, so as to ensure that heat energy is fully utilized, expands furnace upper end
The hot gas of discharge sends into preheating furnace with high temperature draught fan, energy consumption can be further reduced, according to current 1:3 realistic models are tested,
Ton energy consumption can be reduced to 90-100 side, and traditional perforate furnace for expanding perlite has significant advantage.
More than, only it is presently preferred embodiments of the present invention, any formal limitation not is made to the present invention, although this
Invention is disclosed above with preferred embodiment, but is not limited to the present invention, any those skilled in the art,
Do not depart from the range of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
The equivalent embodiment of change, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention is to the above
