The present invention is achieved in that ceramic kiln reducing energy consumption system, is divided into preheating zone, sintering belt and salband in the burner hearth of its body of heater successively, and said sintering belt is provided with some burners; Said preheating zone is connected with TRT, quotes that high temperature air generates electricity in the preheating zone; Said TRT discharging flue gas imports in the burner hearth of preheating zone, can effectively utilize the high-grade energy of preheating zone high temperature like this, but can not influence the production of ceramic kiln.
Alternately in the burner hearth of said preheating zone be provided with some barricades, be used to make the air walking flow process in the preheating zone to be extended, improved the low temperature exhaust heat effect.
The burner hearth lateral wall of said preheating zone is equipped with chuck, and said chuck is connected with warm-air pipe, connects on the said chuck to import blower fan, is used to import air.
The burner hearth of said salband is provided with the first air inducing pipeline and is connected with said preheating zone burner hearth is interior, is used to quote the aeriferous deficiency of waste heat replenish air preheating of salband, and reaches the purpose that waste heat makes full use of, with energy savings.
The burner hearth of said salband is outside equipped with heat exchanger, and said heat exchanger is connected with said warm-air pipe and communicates, and said heat exchanger is connected with said salband through the second air inducing pipeline and communicates.
The flue gas that said TRT comes out is provided with branch line and is connected with heat exchanger through behind the blender, for heat exchanger provides the portion of hot air.
Be provided with stop part between said sintering belt and the said salband, be used to keep the temperature in the sintering belt, improve sintering effect.
Compared with prior art, the present invention has following beneficial effect: (1) makes full use of the bag taste energy of high temperature in the preheating zone, and under the situation that does not influence production, generating electricity supplies other equipment to use, and can reach the optimized reasonable use of resource; (2) make full use of the tail gas of TRT generation and the tail gas of salband and heat air-breathing, reach the purpose of effective recycling thermal source; (3) can on the existing equipment basis, improve, need not to change the existing equipment agent structure, realize very easy; (4) energy savings significantly, less discharging heat loss and environmental pollution.
Description of drawings
Fig. 1 is the structural representation of ceramic kiln reducing energy consumption of the present invention system.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is carried out detailed explanation.
Ceramic kiln reducing energy consumption system, as shown in Figure 1, be divided into preheating zone 3, sintering belt 13 and salband 9 in the burner hearth of its body of heater successively, said sintering belt 13 is provided with some burners 6 that are used for sintering.The burner hearth place of said preheating zone 3 connects TRT 12; Said TRT 12 is quoted preheating zone 3 interior high temperature airs and is generated electricity; The discharging flue gas of said TRT 12 imports in preheating zone 3 burner hearths of said ceramic kiln; Can effectively utilize the high-grade energy of preheating zone high temperature like this, but can not influence the production of ceramic kiln.Alternately in the said preheating zone 3 be provided with some barricades 10, be used to make the air walking flow process in the preheating zone to be extended, improved the effect of low-temperature prewarming.
The burner hearth lateral wall of said preheating zone 3 is equipped with chuck 2, and said chuck 2 connects blower fan 1 through being connected with warm-air pipe 5 communicating pipe 4 on the said chuck 2, be used to import air, and utilize the heat of hearth outer wall to heat, and is used for combustion-supporting.It is to be connected in the burner hearth that said salband 9 is provided with the first air inducing pipeline 18 and said preheating zone 3, is used to quote the deficiency of waste heat replenish air preheating zone 3 air of salband 9, and reaches the purpose that waste heat makes full use of, with energy savings.
The burner hearth of said salband 9 is outside equipped with heat exchanger 8; Said heat exchanger 8 is connected with said warm-air pipe 5 and communicates; Said heat exchanger 8 communicates through being connected in the second air inducing pipeline 19 and said salband 9 burner hearths, is used to quote the waste heat air in the said salband 9, is used for combustion-supporting.Said salband is provided with and imports blower fan 15, is used for air imported being used in the salband 9 mixing with the waste heat air, through exporting in the said heat exchanger 8, causes flow of flue gas too fast to avoid salband 9 formation negative pressure then.Be provided with stop part 16 between said sintering belt 13 and the said salband 9, be used to keep the temperature in the sintering belt 13, to improve sintering effect.The flue gas that said TRT 12 comes out is provided with branch line 7 and is connected with heat exchanger 8 through blender 14 backs, for heat exchanger 8 provides the portion of hot air.Said preheating zone 3 can through pipeline wherein the comparatively Cryogenic air of porch draw, be used for being connected with drying device 17.To make full use of the heat energy in the preheating zone 3, reach the purpose that the heat energy multifunction is utilized, economize on resources.Wherein, the pipeline with air bleed in burner hearth is connected with air exhauster, and in order to reach the pressure in the burner hearth balance, in said burner hearth, is provided with some importing blower fans 15, is used to import air.Said warm-air pipe 5 is provided with autocontrol valve, so that fuel and combustion air reach the mixing match of best combustion.
