Description

A kind of directly burning type energy-saving hot blast furnace

Technical field

The present invention relates to a kind of hot-blast stove, refer in particular to a kind of directly burning type energy-saving hot blast furnace that is provided with the water cleaning door

Background technology

Current known hot-blast stove is to use mechanical ash removing, cleaning door makes trouble, the cleaning door of hot-blast stove will be located at the Gao Rechu of the bottom of radiating tube, part heat runs off at the cleaning door place, a cleaning door can deashing the radiating tube distance shorter, equipment thermal efficiency is low, has a large amount of cigarette ashes to enter in the air when deashing, is unfavorable for the collection utilization of environmental protection and cigarette ash.

Summary of the invention

The utility model provides a kind of hot-blast stove, has overcome the shortcoming of mechanical ash removing, is convenient to make, and thermal efficiency height is beneficial to environmental protection.

For realizing the present invention, the technical measures that adopted are:

A kind of directly burning type energy-saving hot blast furnace, it is a kind of directly burning type hot-blast stove, it is by combustion chamber, fire grate, remains of firebox, smoke pipe and advance exhaust outlet and form,

It is characterized by:

It has water to carry out the device of deashing;

The repeatedly radiating tube of bending that comes to walk in the pipe cigarette is arranged in the stove more, radiating tube directly and air carry out heat exchange;

Radiating tube (3) through repeatedly from bottom to top skewed inflection, does not have cleaning door but the centre is closed in hot-blast stove;

End at the topmost radiating tube of radiating tube is connected to the deashing case (10) that the water deashing is used;

Have on the deashing case and the corresponding deashing pipe of radiating tube (9), also have drainpipe (11) and smoke-collecting apparatus (8);

The air inlet of hot-blast stove (1) is blown by blower fan in the above from top to bottom;

The air outlet of hot-blast stove (7) is in both sides, bottom and back;

There are water collector (13) and drainpipe (12) in the rear portion of combustion chamber.

Adopt tubular cooler, in the many combs that repeatedly bend, walk outside the smoke pipe and directly dispel the heat by air;

The mechanical ash removing that existing hot-blast stove is adopted changes the water deashing into;

Radiating tube can extend repeatedly the dish folding so that heat is fully shed like this, and cleaning door only use one of the radiating tube least significant end just can, easily manufactured, the centre do not have cleaning door reduced hot at radiating tube midway to the loss in the external world;

One oblique shape water collector is flow in the smoke deposition pond by pipe backward by the drainpipe discharge ash of removing from the hot-blast stove rear portion with water.

Its water deashing, middle no cleaning door, a cleaning door that has only least significant end, thereby the pipe of walking cigarette repeatedly bending dish folding extends radiating tube, so not only easily manufactured, and the temperature of hot smoke pipe when outlet is low, the heat utilization efficiency height, can collect comprehensive utilization again through deposition with the cigarette ash that water flows out, thereby realize energy-conserving and environment-protective.

The present invention is mainly as dryer and use for the air-heater of indoor heating.

Description of drawings

Fig. 1 is the lateral vertical profile of hot-blast stove, and Fig. 2 is the back outside plan view of the hot-blast stove dust remover (10) among Fig. 1.

Among the figure, the 1st, the air inlet on hot-blast stove top, at this by blower fan or connect the air port of outside blower fan, the 2nd, the external box of microvave of hot-blast stove, the 3rd, radiating tube, its bottom connects the combustion chamber, and top connects the deashing case, walks cigarette in the pipe, the air outer with pipe carries out heat exchange, its every part straight tube all is the outlet side height, and water flows out smoothly during in order to deashing, the 4th, and the combustion chamber door, the 5th, the fire grate of combustion chamber, the 6th, remains of firebox, the 7th, the air outlet of hot-blast stove, the 8th, cinder catcher, on connect chimney, the 9th, the deashing pipe, every is just relative with radiating tube, and the 10th, the deashing case, the 11st, the drainpipe of deashing lower box part, the 12nd, the drainpipe of rear portion, combustion chamber water collector, the 13rd, the water collector of bottom behind the combustion chamber, its rear portion is low flows out backward in order to water.

The specific embodiment

Be provided with one to the water collector that retreads (13) in the rear end of burner, the water that water flows down from above when making deashing flows backward, the rear portion of water collector picks out the drainpipe (12) of an ash discharge water, and the buck of assembling from water collector is flowed out along drainpipe, flows into collecting-tank from external pipeline;

The outer wall section of combustion chamber is propped with heat-resisting support, and preceding bottom is provided with ash accepting box; In the upper back welding with radiating tube (3) lower end after repeatedly bending and combustion chamber, last termination dust remover (10), the centre is fixed with metallic support, the deashing pipe of burn-oning in the mouth of pipe corresponding section of dust collecting box outside and radiating tube, the mouth of pipe is provided with pipe and covers; All communicate to drainpipe from the rear portion of deashing pipe, deashing case, radiating tube, combustion chamber, and water can pass through from the top down, radiating tube (3) tilts from top to bottom, so that upwards the flowing out and anti-ponding during deashing of hot flue gas;

Be connected to big down smoke-collecting apparatus (8) up and down, its external air-introduced machine and smoke exhaust pipe on the top of deashing case.

External insulation bellows (2) are installed in outside at hot-blast stove, and the air port begins to rehearse in the bottom of bellows;

When giving indoor heating and making the hot-blast stove of large-scale dewaterer, generally air outlet is located at the bottom rear side and air door is installed;

When hot-blast stove was used on the symmetrical box dryer, air outlet generally was located at the side;

The blower fan of downward air draft can be directly installed in air port (1), also can locate to install air-introduced machine in air outlet (7);

During work, hot flue gas is through radiating tube, deashing case, smoke-collecting apparatus, discharge through air-introduced machine and external chimney, through the outer wall of radiating tube and combustion chamber its torrid zone is walked downwards, discharge by the gas outlet (7) at both sides, body of heater bottom or rear portion from the cool breeze that air inlet (1) enters;

When deashing; truce or banking fire are with descent of temperature earlier; a dozen water pipes are stretched into the corresponding heat radiation mouth of pipe of aligning from a pipe of deashing pipe squeezes into water; ash in water will be managed pours in the water; rear portion by the combustion chamber flows down; flow out through water collector (13) and drainpipe (12), thereby water and ash content are fully utilized respectively from Jiang Shui and ash, and play the effect of environmental protection through precipitation.

Cigarette ash in the cinder catcher (10) also water cleans, and water is injected by the deashing mouth of pipe, is flowed out by drainpipe (11), enters in the collecting-tank with the buck that pipeline picks out and drainpipe (12) flows out.
