Abstract
The invention discloses a temperature control type energy-saving shaft kiln. A temperature sensor and a gas sensor are arranged in a kiln body of the temperature control type energy-saving shaft kiln, the temperature sensor and gas sensor are connected with a controller, and the controller is respectively connected with an electric switch for controlling natural gas flow rate and an electric switch for controlling oxygen flow rate. By means of the sensors and electronic control technology, the precise control for the temperature in the kiln and the precise ratio of the natural gas flow rate to the oxygen flow rate can be realized through the controller, temperature sensor, gas sensor and electric switches, and accordingly the natural gas and oxygen are saved.
Description
Technical field
The present invention relates to furnace equipment field, is a kind of shaft furnace specifically.
Background technology
Kiln is the equipment in order to calcining materials or burnt product be built into refractory material, generally be used in and produce cement, lime, roasting, calcined ore and lump material etc., existing kiln is mainly divided into tunnel cave and shaft furnace, be limited by existing technology, be a large amount of wastes that tunnel cave or shaft furnace all exist the energy, energy consumption be high, burn insufficient, discharge dust and pernicious gas, the waste of the energy both improve cost, also result in environmental pollution, to sinter the flow process of refractory raw material plate diamond spar, sintering plate corundum be a kind of industrial oxidation aluminum feedstock, it is that the calcining of ore grinding extraction kiln forms, when sintering plate corundum, raw material is ground by dry powder grinder, ball-type will be processed into can reasonably be heated when sintering and burn till type after raw material milled, raw material during balling-up, the quantitative supply pan-pelletizer of discharge valve is passed through from raw material cabin, when balling-up, powder adds water, make powder and water proportional in pan-pelletizer, naturally grow up to that diameter differs spherical, raw material ball enters in drying oven and dries, shaft furnace sintering plate corundum take natural gas as heat energy, oxygen and natural gas mix with proper proportion, discharge in the air-cooled burner of high speed, and in kiln combustion.
Summary of the invention
Large in order to solve existing shaft furnace energy consumption, not energy-conservation deficiency, the invention provides the energy-conservation shaft furnace of a kind of Temperature Control Type, it adopts electron controls technology, accurately controls the temperature in shaft furnace, and the combined amount of natural gas and oxygen, to reach energy-conservation object.
The technical solution adopted for the present invention to solve the technical problems is: be provided with temperature sensor and gas sensor in the kiln body of the energy-conservation shaft furnace of Temperature Control Type, temperature sensor is connected with controller with gas sensor, and controller is connected with the motor switch controlling oxygen flow with the motor switch controlling gas discharge respectively.
The present invention realizes its object like this: be arranged in controller by temperature required in kiln, the Temperature numerical that controller is passed back according to temperature sensor, by motor switch regulable control natural gas and oxygen flow, to reach set temperature; Natural gas and oxygen content in kiln body are transmitted back to controller by gas sensor, and when kiln temperature arrives the temperature and natural gas content height that set, controller controls by motor switch the flow reducing natural gas; Can accurately realize controlling kiln temperature by controller, temperature sensor, gas sensor, motor switch, and the ratio between accurate formulation gas discharge and oxygen flow.
The invention has the beneficial effects as follows: utilize sensor and electron controls technology, can accurately realize controlling kiln temperature by controller, temperature sensor, gas sensor, motor switch, and the ratio between accurate formulation gas discharge and oxygen flow, thus saved natural gas and oxygen, serve energy-conserving action.
