Abstract
The invention discloses a variable-frequency energy-saving control system of a tunnel kiln and is applicable to a fan system of the tunnel kiln for sintering refractory bricks. A variable frequency controller is connected between each fan and a power supply; main fans are controlled by a pressure sensor and a temperature controller, which are arranged in the tunnel kiln; and based on the high pressure and temperature change of the inside of the tunnel kiln, the rotary speeds of the fans are timely changed, and the air exhaust amount is changed. By changing the rotary speeds of the fans, the blind operation probability of the fans is greatly reduced, the unreasonable wasting of energy sources is avoided, the temperature and pressure of the inside of the tunnel kiln are particularly stabilized, and the quality of products is guaranteed. A test shows that: by adoption of the variable-frequency energy-saving control system of the tunnel kiln, one third of electricity can be saved, and noise and mechanical abrasion are reduced.
Description
Technical field
The present invention relates to a kind of electricity consumption energy-saving control system, be specially a kind of electricity-saving control system that is applicable to tunnel cave.
Background technology
Tunnel cave is continuous burning kiln, and product gets into from kiln hood, and through the preheating zone preheating, the entering clinkering zone is ejected from the kiln tail after firing and getting into the salband cooling then.Pressure regime in the sintering procedure in the kiln, temperature and burn till back atmosphere and mainly lean on blower fan control, though the tunnel cave heat utilization efficiency is higher, output is big; Labour intensity is low, if but control badly, kiln inner pressure system and atmosphere will greatly influence product quality; And because blower motor power is big, and quantity is many, power consumption is big; An ordinary crossing kiln promptly is equipped with 7 typhoon machines, and general power reaches 150KW, and the energy conservation potential of its existence is very big.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, designed a kind of tunnel cave energy saving control system of frequency conversion in use, it is big to have solved in the present tunnel cave machine consumption, problems such as temperature control instability.
A kind of tunnel cave energy saving control system of frequency conversion in use; Comprise the switching device that blower fan and control blower fan are opened or closed; It is characterized in that described blower fan comprises the oven dry smoke exhaust fan A1 that is communicated with dry kiln; Air blast A4, combustion fan A5, waste heat are extracted blower fan A6, cooling blower A7 out under the main smoke discharging blower fan A2 that is communicated with tunnel cave, kiln down smoke-discharging blower fan A3, the kiln; Be provided with frequency-variable controller D between each blower fan and the power supply, in tunnel cave, be provided with pressure sensor B and temperaturecontrol sensor C, wherein with on the frequency converter that main smoke discharging blower fan A1 is connected be connected to pressure sensor B; The frequency converter of air blast A4 is connected with high temperature section temperature sensor C1 under kiln down smoke-discharging blower fan A3 and the kiln, and the frequency converter of cooling blower A7 is connected with cooling section temperature sensor C2.
Described tunnel cave energy saving control system of frequency conversion in use is characterized in that pressure sensor B is arranged on the intensification section of tunnel cave, and high temperature section temperature sensor C1 and cooling section temperature sensor C2 are separately positioned on the high temperature section and the cooling section of tunnel cave.
Tunnel cave energy saving control system of frequency conversion in use of the present invention adopts sensor to combine with frequency converter, the big and variations in temperature with kiln inner pressure; The rotating speed of machine in time changing, and then change exhaust air rate, through above-mentioned control rotation speed of fan; Significantly reduced the blindness running of blower fan; Having reduced the energy wastes for no reason, has particularly stablized kiln temperature and pressure, has guaranteed product quality.Through test, adopt this technology, can economize on electricity 1/3rd, reduced noise and mechanical wear.
Description of drawings
Fig. 1 is a tunnel cave energy saving control system of frequency conversion in use structural representation.
Among the figure, A1-is dried smoke exhaust fan; The A2-main smoke discharging blower fan; A3-kiln down smoke-discharging blower fan; Air blast under the A4-kiln; The A5-combustion fan; The A6-waste heat is extracted blower fan out; The A7-cooling blower; The B-pressure sensor; C1-high temperature section temperature sensor; C2-cooling section temperature sensor; The D-frequency-variable controller.
The specific embodiment
Shown in Figure 1, tunnel cave energy saving control system of frequency conversion in use of the present invention, through the mode that is connected a frequency converter between blower fan and the power supply respectively is installed in the tunnel cave with sintered refractory block, the running of control blower fan, realize energy-conservation, the effect of economize on electricity.Place among Fig. 1 between oven dry smoke exhaust fan A1 and the AC power of dry kiln a frequency-variable controller D is installed.Air blast A4, combustion fan A5, waste heat are extracted out between blower fan A6, cooling blower A7 and the power supply and are provided with frequency-variable controller D under the main smoke discharging blower fan A2 that is communicated with tunnel cave, kiln down smoke-discharging blower fan A3, the kiln; In tunnel cave, be provided with pressure sensor B and temperaturecontrol sensor C; Wherein with on the frequency converter that main smoke discharging blower fan A1 is connected be connected to pressure sensor B; The frequency converter of air blast A4 is connected with high temperature section temperature sensor C1 under kiln down smoke-discharging blower fan A3 and the kiln, and the frequency converter of cooling blower A7 is connected with cooling section temperature sensor C2.
During work, when atmospheric pressure and kiln inner pressure changed, pressure sensor was through control frequency conversion output; Change the main smoke discharging blower fan rotating speed, and then guarantee that kiln inner pressure is stable, temperature sensor is through control frequency conversion output; Change kiln leeward and cooling air size, control get off temperature and products temperature.The frequency-variable controller that oven dry smoke exhaust fan A1, combustion fan A5, waste heat are extracted blower fan A6 and cooling blower A7 out is then got final product by Artificial Control according to situation in the kiln.
Embodiment, oven dry smoke exhaust fan A1,15KW, tunnel cave main smoke discharging blower fan A2,30KW, kiln down smoke-discharging blower fan A3,15KW, air blast A4 under the kiln, 15KW, combustion fan A5,30KW, waste heat are extracted blower fan A6,22KW, cooling blower A7,22KW out.After using frequency-variable controller and pressure, temperature sensor, realize economize on electricity about about 1/3rd.Energy-saving effect is very obvious, regains whole investments for trnasforming urban land then.
