A smoke collecting chamber arranged at the upper portion of the combustion chamber is communicated with the smoke flue. A smoke outlet of the smoke flue is communicated with the exterior of the furnace body. The air flue is provided with at least one air inlet and at least one air outlet, wherein the air inlet is communicated with the exterior of the furnace body, the air outlet is communicated with the external world, the air inlet is connected with an air blower, the air inlet of the air flue is located in the area, away from the combustion chamber, of the air flue, and the air outlet of the air flue is located in the area, close to the combustion chamber, of the air flue. When the hot blast furnace works, air enters the air flue and then achieves heat exchange with smoke inside the smoke flue, after the air enters the air flue, the air enters the lower-temperature environment and the high-temperature environment successively, the temperature of the air is increased step by step, the air and the smoke can conduct sufficient heat exchange, and the heat collecting effect of the air is more ideal.

Description

Hot-blast stove

Technical field

The utility model relates to a kind of hot-blast stove.

Background technology

The booth of cultivation fowl poultry or the booth of planting vegetable adopt hot-blast stove heating conventionally, are beneficial to promote the growth of animal and plant, improve quantum of output.

Existing a kind of hot-blast stove has following basic structure: in body of heater, be provided with burner hearth, the bottom of burner hearth and bottom have the fuel inlet and the waste outlet that communicate with the body of heater external world, between body of heater and burner hearth, be provided with the flue and the air flue that are formed by some dividing plates, adjacent and the staggered roundabout distribution in body of heater of flue and air flue, burner hearth communicates with flue, the outlet flue of flue communicates with the body of heater external world, and air flue has the air inlet and the gas outlet that communicate with the body of heater external world, and each air inlet and air blast join.This hot-blast stove by air be conveyed in air flue with flue in flue gas carry out discharging after heat exchange, can make the air themperature of discharging raise.But above-mentioned this hot-blast stove is because its air flue air inlet and the setting position of gas outlet are reasonable not, therefore the deficiency existing is: the heat exchange that enters the flue gas in air and the flue in air flue is abundant not, the temperature of air can not fully raise, and causes the effect of heating not good enough.

Utility model content

The purpose of this utility model is to provide a kind of rational in infrastructure, hot-blast stove that heat exchanger effectiveness is high.

For achieving the above object, the utility model adopts following scheme: a kind of hot-blast stove, in body of heater, be provided with burner hearth, the bottom of burner hearth and bottom have the fuel inlet and the waste outlet that communicate with the body of heater external world, between body of heater and burner hearth, be provided with the flue and the air flue that are formed by some dividing plates, adjacent and the staggered roundabout distribution in body of heater of flue and air flue, the fume collecting chamber that upper furnace has communicates with flue, the outlet flue of flue communicates with the body of heater external world, air flue has at least one air inlet communicating with the body of heater external world and at least one and the extraneous gas outlet communicating, each air inlet and air blast join, the air inlet of air flue is positioned at its region away from burner hearth, the gas outlet of air flue is positioned at its region near burner hearth.

From such scheme, the hot-blast stove that the utility model newly provides is in the time of work, start air blast, air enter after air flue with flue in flue gas realize heat exchange, because flue is higher, relative lower away from the temperature in burner hearth region near the temperature in the region of burner hearth position with air flue, so air enters after air flue, be introduced into low temperature environment, then enter hot environment, the progressively raising of air themperature, air and flue gas can fully carry out heat exchange, air to adopt thermal effect more desirable.

The utility model is rational in infrastructure, heat utilization rate is high, heating effect is good.

The specific embodiment

As shown in Fig. 1 to 5

This hot-blast stove comprises body of heater 1, burner hearth 2 and five chambers.

Burner hearth 2 is arranged on body of heater 1 inside, and the 2a of fume collecting chamber is arranged at the top of burner hearth 2, and the bottom of burner hearth 2 and bottom have the fuel inlet 2b and the waste outlet 2c that communicate with the body of heater external world.

Between body of heater 1 and burner hearth 2, become the chamber of five sealings by baffle for separating, according to being followed successively by the first chamber 1a, the second chamber 1b, the 3rd chamber 1c, the 4th chamber 1d and the 5th chamber 1f by body of heater 1 sidewall to burner hearth 2 sidewall direction.

On body of heater 1, have two air inlet 1h that communicate with the first chamber 1a, the upper correspondence of each air inlet 1h is joined with an air blast 4a, the first chamber 1a bottom is communicated with by the first tube connector 3a with the 3rd chamber 1c bottom, the top of the 3rd chamber 1c is communicated with by the second tube connector 3b with the 5th chamber 1f top, on body of heater 1, have a gas outlet 1j who communicates with the 5th chamber 1f bottom, the first chamber 1a, the first tube connector 3a, the 3rd chamber 1c, the second tube connector 3b and the 5th chamber 1f form air flue jointly, the air inlet 1h of air flue is positioned at its region away from burner hearth, the gas outlet 1j of air flue is positioned at it near burner hearth region

Body of heater 1 top has an outlet flue 1g who communicates with the second chamber 1b, on outlet flue 1g, be provided with an air-introduced machine 4b, the bottom of the second chamber 1b is communicated with by two the 3rd tube connector 3c with the 4th chamber 1d bottom, the 4th chamber 1d top is communicated with by the 4th tube connector 3d with the 2a of fume collecting chamber of burner hearth 2, and the 4th chamber 1d, the 3rd tube connector 3c, the 4th tube connector 3d and the second chamber 1b form flue jointly.
