The combustion fan is connected with an air main pipe, the air main pipe is connected with a cold air pipe and a plurality of air inlet pipes, and the air inlet pipes are connected with a hot air pipe through air pre-heaters respectively. The cold air pipe is connected with the air pre-heaters, the hot air pipe is connected with a plurality of hot air branch pipes, and the hot air branch pipes are connected with nozzles. The hot air branch pipes which are connected to the same hot air pipe are further connected with a balance pipe, and a thermocouple is arranged on the hot air pipe. According to the air pipe line system of the thermal treatment furnace, air flow and pressure can be well controlled, and the combustion state is stabilized.
Description
Technical field
The utility model relates to the air pipe system of heat-treatment furnace.
Background technology
Heat-treatment furnace is widely used, but heat-treatment furnace has following problems at present:
Air preheater likely can be overheated.
Each control area of burning, there are several burners to be connected with hot air duct, the pipeline in the zone that each burning is controlled is very long, end from the air intake starting end to pipeline has certain distance, cause the first section pressure from end wind different, the blast difference of each burner can cause the combustion position difference of burner, and burning that can not be stable can cause increasing of energy resource consumption, and causes the furnace atmosphere difference.
The utility model content
The purpose of this utility model is to provide a kind of air pipe system of heat-treatment furnace, and it can well control flow and the pressure of wind, smooth combustion state.
For achieving the above object, the technical solution of the utility model is the air pipe system of a kind of heat-treatment furnace of design, comprise combustion fan, combustion fan connects air header, and air header connects cool air hose and some blast pipes, blast pipe connects warm-air pipe by air preheater separately, cool air hose connects air preheater, and warm-air pipe connects some hot blast manifolds, and hot blast manifold connects burner, each hot blast manifold that is connected to same warm-air pipe also connects balance pipe, and warm-air pipe is provided with thermocouple.
Preferably, described air header is provided with pressure switch.
Preferably, described cool air hose is provided with magnetic valve.
Preferably, described blast pipe is provided with flow-through orifice and regulating butterfly valve.
Preferably, described hot blast manifold is provided with butterfly valve.
Advantage of the present utility model and beneficial effect are: a kind of air pipe system of heat-treatment furnace is provided, and it can well control flow and the pressure of wind, smooth combustion state.
From blower fan, air header out is through distributor; be divided into a plurality of branch roads (blast pipe); lead to respectively the air inlet of air preheater; in order to protect heat exchanger; having installed especially a road smaller branch pipe (cool air hose) additional is mixed cold to air preheater; in the situation that the overheated heat exchanger of air preheater is blown a cold wind over, protect air preheater.
Install respectively flowmeter (flow-through orifice) and motorized adjustment butterfly valve additional on blast pipe, control the wind flow of blast pipe.
Each hot blast manifold that is connected to same warm-air pipe also connects balance pipe, carrys out the pressure in this combustion zone of balance, makes it stable to the burner air feed, reaches energy-saving and cost-reducing and stable furnace atmosphere.
Install temperature thermocouple on warm-air pipe additional, the hot blast temperature of measurement feeds back to air feed flowmeter and electric control valve, the flow of stable adjusting wind.
By above pipeline adjustment, can well control flow and the pressure of wind, the smooth combustion state.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The concrete technical scheme of implementing of the utility model is:

Described hot blast manifold 7 is provided with butterfly valve 71.
From blower fan, air header out 2 is through distributors; be divided into a plurality of branch roads (blast pipe 4); lead to respectively the air inlet of air preheater 5; in order to protect heat exchanger; having installed especially a road smaller branch pipe (cool air hose 3) additional is mixed cold to air preheater 5; in the situation that the overheated heat exchanger of air preheater 5 is blown a cold wind over, protect air preheater 5.
Install respectively flowmeter (flow-through orifice) and motorized adjustment butterfly valve additional on blast pipe 4, control the wind flow of blast pipe 4.
Each hot blast manifold 7 that is connected to same warm-air pipe 6 also connects balance pipe 9, carrys out the pressure in this combustion zone of balance, makes it stable to burner 8 air feeds, reaches energy-saving and cost-reducing and stable furnace atmosphere.
Install temperature thermocouple 10 on warm-air pipe 6 additional, the hot blast temperature of measurement feeds back to air feed flowmeter and electric control valve, the flow of stable adjusting wind.
By above pipeline adjustment, can well control flow and the pressure of wind, the smooth combustion state.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
