Abstract

The utility model discloses a combustible waste gas reuse hot blast stove, which includes a combustion chamber, a heat exchange chamber and a seal product heating room, wherein the combustion chamber is connected with the heat exchange chamber through a pipeline; a blower is connected with the heat exchange chamber; a chimney is arranged on the heat exchange chamber; the heat exchange chamber is connected with the seal product heating room through a hot air passage; and a waste gas reclaiming passage is arranged in the seal product heating room and communicated with the combustion chamber. The hot blast stove has the advantages that after a to-be-heated object in the seal product heating room is heated, the exhausted combustible waste gas is delivered to the combustion chamber in a centralized manner, and is reused to obtain partial heat energy through combustion in the combustion chamber; simultaneously, organic materials contained in the waste gas are decomposed into water vapor, carbon dioxide, other gases, or ash, so that the pollution of the exhaust waste gas to the environment is reduced.

Description

Combustible exhaust gas utilizes hot-blast stove again

Technical field

The utility model relates to a kind of combustible exhaust gas and utilizes hot-blast stove again.

Background technology

Hot-blast heater use in several Baidu of heating temperature range now is comparatively extensive, can use fuel such as combustion gas, fuel oil, fire coal.But some heating object is after being heated, and the combustible exhaust gas of being discharged is not just handled and directly entered atmosphere, and environment has been caused pollution (such as peculiar smell and pernicious gas); The waste gas treatment equipment that then increases in addition that has comes waste gas is handled, though reduced pollution on the environment like this, the also corresponding production cost that increased.Owing to all waste gas is not utilized again, therefore caused the wasting of resources, be unfavorable for energy-saving and emission-reduction.

The utility model content

The utility model has overcome shortcoming of the prior art, provides a kind of combustible exhaust gas to utilize hot-blast stove again.

The technical solution of the utility model is: a kind of combustible exhaust gas utilizes hot-blast stove again, comprise combustion chamber, heat-exchanging chamber and sealed product heating clamber, described combustion chamber is connected with heat-exchanging chamber by pipeline, air blast is connected with heat-exchanging chamber, heat-exchanging chamber is provided with chimney, and heat-exchanging chamber is connected with the sealed product heating clamber by hot-air channel; Be provided with the waste gas recovery approach at described sealed product heating clamber, described waste gas recovery approach is communicated with the combustion chamber.

Between described waste gas recovery approach and combustion chamber, the combustion chamber air blast is set.

Described waste gas recovery approach is provided with air exhauster.

Described waste gas recovery approach is provided with storage device.

Compared with prior art, the utility model has the advantages that: heating object is after being heated in the sealed product heating clamber, and the combustible exhaust gas of being discharged is concentrated and is transported to the combustion chamber, and waste gas passes through burning, recycling acquisition partial heat energy in the combustion chamber; Simultaneously the organic gas that contains in the waste gas then is decomposed into gas such as water vapour and carbon dioxide or becomes ashes, and discharge can reduce the pollution to environment like this.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

A kind of combustible exhaust gas utilizes hot-blast stove again, as shown in Figure 1, comprise: combustion chamber 1, pipeline 2, air blast 3, chimney 4, heat-exchanging chamber 5, hot-air channel 6, sealed product heating clamber 7, waste gas recovery approach 8 and combustion chamber air blast 9 etc., wherein: combustion chamber 1 is connected with heat-exchanging chamber 5 by pipeline, air blast 3 is connected with heat-exchanging chamber 5, chimney 4 is set on heat-exchanging chamber 5, and heat-exchanging chamber 5 is connected with sealed product heating clamber 7 by hot-air channel 6; Be provided with waste gas recovery approach 8 at described sealed product heating clamber 7, described waste gas recovery approach 8 is communicated with combustion chamber 1; Between waste gas recovery approach 8 and combustion chamber 1, combustion chamber air blast 9 is set.

Operation principle of the present utility model is:

1 burning produces high-temperature furnace gas in the combustion chamber for combustion gas, fuel oil, fire coal.High-temperature furnace gas advances people's heat-exchanging chamber 5 by pipeline 2, and the cold wind that blows into air blast 3 carries out heat exchange.Furnace gas after the cooling is discharged to the atmosphere from chimney 4.The cold wind that air blast 3 blows into has been exchanged into hot blast in heat-exchanging chamber 5.This hot blast does not contain impurity and the ashes in the furnace gas.Hot blast enters sealed product heating clamber 7 by hot-air channel 6, and product is heated.Heating-up temperature can be controlled the burning of air blast 3 or combustion chamber 1 and regulate control.This is existing hot-blast stove operation principle.Its waste gas directly is discharged in the atmosphere, perhaps enters in the emission-control equipment and handles.

The utility model is the combustible exhaust gas that sealed product heating clamber 7 heating products are produced, and concentrates by waste gas recovery approach 8.Waste gas in the waste gas recovery approach 8 is blown into combustion chamber 1 internal combustion with combustion chamber air blast 9, enters reciprocation cycle.

Waste gas recovery approach 8 also can be provided with air exhauster, is used to quicken the discharge of combustible exhaust gas and the temperature that cooling device reduces combustible exhaust gas is set.Also the storage device stores combustible exhaust gas can be set, so that evenly enter combustion chamber 1 internal combustion.
