Abstract
The utility model relates to a hot air combustion-supporting device in a kiln cavity. The hot air combustion-supporting device in the kiln cavity comprises a heat exchange tube set, a connecting tube, an air blower and an air outlet tube. The heat exchange tube set is located on a kiln quenching belt and comprises a plurality of heat exchange tubes, two ends of each heat exchange tube both penetrate out of a kiln, one end of each heat exchange tube is connected with one end of the connecting tube, the other end of the connecting tube is connected with an air inlet of the air blower, and an air outlet of the air blower is connected with the air outlet tube. According to the hot air combustion-supporting device in the kiln cavity, the heat exchange tubes transversely penetrate through the kiln quenching belt, air in the heat exchange tubes is pre-heated by high temperature in the quenching belt, the air after being pre-heated is sent to a burner of the kiln to carry out supporting combustion, a pressure environment in the kiln quenching belt is not influenced, heating to combustion-supporting air is achieved, and meanwhile the quenching belt is helped to be cooled.
Description
Technical field
The utility model relates to hot blast auxiliary combustion equipment in a kind of kiln chamber.
Background technology
Existing ceramic roller kiln burner combustion air source great majority are directly to utilize air, but prove from theory and practice, improve the consumption that the combustion air temperature can effectively be saved furnace fuel.There have been a lot of roller way kilns to carry out the improvement project of combustion air heating in the industry, in the combustion-supporting heating transformation project of some roller way kilns, in order to improve the combustion air temperature, directly in the chilling casing, take high-temperature flue gas away, cause roller way kiln chilling band pressure environment unusual, influence the kiln ordinary production.
The utility model content
The utility model is in order to overcome the defective of above-mentioned prior art, provides a kind of and adopted high-temperature gas after the heating as hot blast auxiliary combustion equipment in the kiln chamber of combustion-supporting gas.
In order to reach the foregoing invention purpose, the technical solution of the utility model is: hot blast auxiliary combustion equipment in a kind of kiln chamber, comprise set of heat exchange tubes, tube connector, air blast, escape pipe, described set of heat exchange tubes is positioned at kiln chilling band, set of heat exchange tubes comprises some heat exchanger tubes, the heat exchanger tube two ends all pass kiln and wherein an end be connected with tube connector one end, the tube connector other end connects blower inlet, blower outlet connects escape pipe.
Preferably, described heat exchanger tube is internal diameter 12～18cm pipe.
Preferably, described tube connector is the flexible pipe that is connected with heat exchanger tube coupling.
Preferably, described set of heat exchange tubes is made as the two rows heat exchanger tube, and two settings of row between the heat exchanger tubes are spaced apart 0.5～1.5m, is spaced apart 0.5～1.5m between the heat exchanger tube in every row.
The hot blast auxiliary combustion equipment is by crossing heat exchanger tube on kiln chilling band in the utility model kiln chamber, with the high temperature in the chilling band with the air preheat in the heat exchanger tube, and then it is combustion-supporting that the air after the preheating is delivered to kiln burner place, neither the pressure environment in the kiln chilling band is impacted, realized the heating to combustion air again, simultaneously, also help the cooling of chilling band.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Figure 1A-A position profile figure.
The specific embodiment
Below in conjunction with concrete the drawings and specific embodiments the utility model is described further:
As shown in Figure 1, 2, hot blast auxiliary combustion equipment in a kind of kiln chamber, comprise set of heat exchange tubes, tube connector 2, air blast 3, escape pipe 4, described set of heat exchange tubes is positioned at kiln chilling band, set of heat exchange tubes comprises some heat exchanger tubes 1, heat exchanger tube 1 two ends all pass kiln and wherein an end be connected with tube connector 2 one ends, tube connector 2 other ends connect air blast 3 air inlets, air blast 3 air outlets connect escape pipe 4.Described heat exchanger tube 1 is internal diameter 15cm pipe, thickness of pipe wall 0.5cm.Described tube connector is the plastic flexible pipe that mates with heat exchanger tube.The setting that described set of heat exchange tubes is made as between two rows heat exchanger tube 1, the two row heat exchanger tube is spaced apart 1m, is spaced apart 1m between the heat exchanger tube in every row.
During work, normal temperature air is drawn into heat exchanger tube under the effect of air blast 3, because heat exchanger tube is positioned at the higher chilling band of temperature, normal temperature air in the pipe is heated, air after the heating supplies to combustion zone through connecting flexible pipe, air blast and escape pipe again, finally finishes combustion-supportingly near burner by pipeline, adopts this device can effectively improve the temperature of combustion air, thereby improve the efficiency of combustion of fuel, economize on resources.
