Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of burner and bituminous mixing plant.
Background technology
In bituminous mixing plant, burner is one of most important key core parts, and the service behaviour of burner has directly determined bituminous mixing plant converted products quality, production capacity and processing cost, is also the important evaluation index to bituminous mixing plant performance quality.The burner major part that bituminous mixing plant adopts both at home and abroad is at present to use fuel oil, the usage ratio of combustion gas in recent years also starts to increase, also have a small part to adopt coal dust technology (being mainly domestic small-sized station), according to the trend of energy resource structure development from now on, the production of bound bitumen mixing plant and process characteristic, fuel oil and combustion gas class burner will occupy dominant position in bituminous mixing plant.
At present, oil burner, according to the difference of fuel oil, is divided into heavy oil direct combustion type and the mixed combustion type of weight oil.Heavy oil direct combustion type burner is higher to the quality requirements of heavy oil, and inferior heavy oil is more owing to containing impurity, and viscosity is higher, easily causes the obstruction of pipe oil circuit and spray gun, the heavy oil difficulty of directly burning, thus cause loss of ignition.
The general combustion-supporting light oil adopting of the mixed combustion type burner of weight oil is diesel oil, and heavy oil is fuel oil.Between weight oil, intersolubility is to necessarily require, if contain impurity and other pollutant in heavy oil, heavy oil mixes the coking that easily reacts with diesel oil, cause the obstruction of pipe oil circuit and spray gun, thereby causes loss of ignition.
Fig. 1 is the process chart of burner.Burner carries out the switching of diesel oil and heavy (slag) oil by fuel oil transfer valve, be burner delivering fuel by gear residual oil pump, and fuel oil enters airborne heater through fuel metal flexible pipe and heats, and ensures combustion oil viscosity and fluency; By solenoid fuel injection valve control combustion oil injection.Compressed air provides atomization gas by air metal hose and air filter for spray gun.Combustion gas, by gas electromagnetic valve and ignition transformer control, for burning torch provides combustion gas, is carried out ignition operation.Usually, before igniting and after flame-out, must carry out air pressure purging to fuel pipe, it is clean the long-pending oil in fuel pipe by compressed air that air pressure purges, and prevents long-pending oil condense obstruction fuel pipe and spray gun.Be on fuel pipe, to be wound around electric tracing line to the method for fuel pipe preheating at present, the fuel pipe after preheating can reduce combustion oil viscosity, improves circulation.
In actual use, this kind of Purge methods effect is not good enough, cleans not thoroughly, easily causes fuel pipe and spray gun to stop up, thereby causes loss of ignition.There is heating dead angle in the preheating method that is wound around electric tracing line, inhomogeneous to the preheating of fuel pipe, firing rate is slow, efficiency is low.
Summary of the invention
In view of this, the present invention proposes a kind of burner and bituminous mixing plant, stops up to solve fuel pipe and spray gun, causes the problem of loss of ignition.
On the one hand, the invention provides a kind of burner, comprise spray gun, burning torch, fuel pipe, fuel gas pipeline, sweep gas pipeline, atomization gas pipeline, the output of fuel pipe is connected with spray gun, the output of fuel gas pipeline is connected with burning torch, the output of atomization gas pipeline is connected with spray gun, sweep gas heater is installed on sweep gas pipeline or supplies with high-temperature gas on sweep gas pipeline, main fuel tap is installed on fuel pipe, and the output of sweep gas pipeline and spray gun to the fuel pipe between main fuel tap is connected.
Further, the input of sweep gas pipeline is connected with atomization gas pipeline.
Further, on sweep gas pipeline, blow down valve is installed, blow down valve is between sweep gas heater and the input of sweep gas pipeline.
Further, atomization air valve and atomization gas pressure switch are installed on atomization gas pipeline, the input of sweep gas pipeline and atomization air valve to the atomization gas pipeline between spray gun is connected.
Further, circulating valve and fuel pump are installed on fuel pipe, circulating valve, between main fuel tap and fuel pump, is provided with oil return opening on circulating valve.
Further, igniting gas valve is installed on fuel gas pipeline.
Further, the output of sweep gas pipeline and fuel pipe tie point are near the outlet of main fuel tap.
In addition, the present invention also provides a kind of bituminous mixing plant, comprises above-mentioned burner.
The invention provides a kind of burner and bituminous mixing plant, sweep gas heater is installed on sweep gas pipeline or supplies with high-temperature gas on sweep gas pipeline, utilize high-temperature gas to fuel pipe and lasting heating and the purging of spray gun.This kind of pre-thermal purging function is even to the preheating of fuel pipe, and preheating speed is fast.By this kind of preheating purge, reach the effect of cleaning and heated fuel oil pipeline and spray gun.Lasting heating and purging, the fuel oil of leaving in fuel pipe, coking material and impurity are removed and are more prone to and thoroughly.On the other hand, in the time of normal ignition, the fuel pipe after purging still can keep certain temperature, and the process that the fuel oil of being come by main fuel tap enters spray gun through this section of pipeline is more smooth and easy, can be not smooth because of the circulation too low and that cause of fuel pipe temperature.Thereby make burning think highly of (slag) oil, directly burning is convenient easily, can not cause loss of ignition.
