Abstract

The utility model relates to a novel hot-blast stove which comprises a stove body with a cold air inlet opening, a hot air outlet opening and a fume exhaust outlet opening. The hot-blast stove is characterized in that the cold air inlet opening is over against a fume exhaust outlet pipe. Since the cold air inlet opening is over against the fume exhaust outlet pipe, as soon as the cold air enters into the hot-blast stove, the heat transfer of the wall body of the fume exhaust outlet pipe is heated, the heat energy can be better utilized compared with the condition that the cold air inlet opening of the former hot-blast stove is arranged at other positions, thereby the heat utilization ratio of the hot-blast stove can be improved.

Description

Novel hot-blast stove

Technical field:

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

Background technology:

Hot-blast stove is a kind of device that hot blast is provided to drying oven, the flue gas of hot-blast stove only just emits through an interlayer usually at present, cold wind is by the just output of heat exchange of two interlayers, also have a large amount of heat energy just to be slatterned in vain in the flue gas, and more existing hot-blast stoves also fail to utilize well this partial heat energy in addition; What also have is exactly that these hot-blast stoves normally carry out work in the mode of natural draught system, can't control well the hot blast temperature that hot-blast stove produces.

Summary of the invention:

The purpose of this utility model is to provide a kind of novel hot-blast stove, and this hot-blast stove has been strengthened the absorption to tail gas heat quantity, can utilize the heat energy that produces in the hot-blast stove better, improves the heat exchanger effectiveness in the hot-blast stove greatly, plays energy-conserving action.

The utility model hot-blast stove, comprise have the cold wind import, the body of heater of hot-blast outlet and smoke evacuation outlet, it is characterized in that: described cold wind import is facing to the smoke evacuation outlet.

The utility model faces toward the smoke evacuation outlet conduit by the cold wind import, cold wind obtains heating because of the heat transmission of smoke evacuation outlet conduit wall body when making cold wind one enter hot-blast stove, hot-blast stove cold wind import more in the past is arranged on other position can utilize heat energy better, thereby has improved the utilization rate of hot-blast stove heat energy.

Description of drawings:

Fig. 1 is an organigram of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment:

The utility model hot-blast stove, comprise have cold wind import 1, the body of heater 4 of hot-blast outlet 2 and smoke evacuation outlet 3, cold wind import 1 is facing to smoke evacuation outlet 18.

In order effectively to regulate the hot blast temperature that hot-blast stove produces, be equiped with on the smoke evacuation outlet conduit in order to regulate the air-introduced machine 5 of flue gas flow rate in the flue, thereby air-introduced machine is set at smoke evacuation outlet place can effectively controls temperature in the stove, when temperature in the stove is low, strengthens air-introduced machine speed and improve temperature in the stove; When temperature in the stove is too high, turns off air-introduced machine and can reduce temperature in the stove, thereby greatly facilitate control.

Above-mentioned body of heater 4 comprises the burner hearth 6 of being located at the middle part and covers on the burner hearth periphery in order to form the internal layer air channel, middle level flue 7 and outer air channel 8 three from inside to outside diameters and the cage A that increases highly step by step, B, C, be provided with the intraformational bed flue 9 that constitutes by two tubular plates in the described internal layer air channel, described intraformational bed flue 9 tops are communicated with the exhaust opening 10 of burner hearth, the bottom is communicated with middle level flue 7, described cage A and hearth outer wall 11 form the internal layer air channel, intraformational bed flue 9 is separated into air channel, middle level 12 and nexine air channel 13 to the internal layer air channel again, 13 bottoms, described nexine air channel are provided with the hot-blast outlet 2 that passes body of heater, the below in air channel, middle level 12 is provided with the connector 15 that is communicated with outer air channel, described smoke evacuation outlet 18 is located at middle level flue 7 tops, and described cold wind import 1 is located between 8 tops, outer air channel and the smoke exhaust pipe 18.
