Description
The utility model belongs to automatic burning device.The heavy oil emulsive technology is early to be adopted by people at present, it can reach purpose of energy saving really, its reason is after heavy oil infiltrates emulsifying additive, furol viscosity is reduced, because of emulsifying agent contains extremely strong hydrophilic radical and lipophilic group, the interfacial tension of oil and water is reduced greatly, and the oil that sprays through nozzle forms superfine extremely equal Water-In-Oil system.Oil droplet is very little, through " effect of micro-explosion " and " water-gas reflection " in the stove hall, improve efficiency of combustion greatly, but good like this combustion efficiency, must be on the rational proportion of oil and water, to realize, otherwise be to reach optimum efficiency, solve this difficult problem, at first will solve full automatic equipment.Because the first step is to solve oil pressure stability automatically, could solve the profit proportioning on this basis.Solve after these two problems burning competence exertion optimum state.
Tubing pressure was to come steady pressure by returning oil in the past, the one, and oil circuit is a dynamic environment, stability is very poor, and is frequent as manually to align, and the 2nd, return the flow that oil increases pump, also waste a lot of electric energy simultaneously.General profit proportioning is artificial levelling, because the oil circuit pressure instability, essence can not form the profit proportioning and follow the tracks of, and so also just can not bring into play optimal combustion state, so combustion efficiency is poor, wastes energy greatly.
The purpose of this utility model provides a kind of heavy oil emulsive automatic burning device, utilize emulsifying agent to mix with the automatic of water, again emulsified water is mixed with heavy oil, realize that by the control of PiD adjuster and the control of variable-frequency governor heavy oil mixes with the automatic optimal proportioning of emulsifying agent, to reach the best combustion effect, the purpose of energy savings.
Structural design of the present utility model is achieved in that the heavy oil emulsive automatic burning device is made up of two parts, the one, by the heavy oil fuel tank, two emulsified water water tanks, emulsifier and middle connecting line and valves are formed, and another is that the control aspect is made up of the variable-frequency governor and the PiD adjuster of programmable controller, two pumps.Its detailed structure is that heavy oil tank is connected with gear pump through valve, two emulsified water water tank tops are equipped with respectively and are added water solenoid valve, take out the emulsifying agent self priming pump, thermometer, the water level meter, the self priming pump front connects the emulsifying agent cylinder, its outlet is connected with tubing pump respectively, tubing pump output is connected with spinner flowmeter through valve again after respectively hanging oneself and closing up behind the check valve, spinner flowmeter is connected with gear pump with the heavy oil tank valve through valve simultaneously together, gear pump output is connected with emulsifier through valve, emulsifier output is connected with flowmeter through valve, flowmeter is output as heating furnace and disputes and chew, the input of the programmable controller of control circuit respectively with the PiD adjuster, the variable-frequency governor output connects, be connected with the water level meter with the thermometer on emulsified water water tank top simultaneously, the programmable output respectively with the water solenoid valve that adds of emulsified water water tank, the emulsifying agent self priming pump connects, be connected to warning system simultaneously, one of them is connected variable-frequency governor with tubing pump, another is connected with gear pump, the PiD input is connected with oil feed line through the Pressure gauge that changes far away, and its operation principle is:
By the oil pipe line actual pressure, by the teletransmission Pressure gauge, the pressure signal control PiD of output, adjuster output 4-20mA variable signal control oil pump variable-frequency governor, form the oil pressure closed-loop control system solves emulsified water on the stable basis of oil pressure proportioning like this and follow the tracks of, emulsified water be along with the fuel injection pressure signal variable with motion tracking, it also is controlled by the PiD adjuster, basic like this solution profit from motion tracking, the flow-control of emulsified water is to be aligned by pump variable frequency speed regulator positive definite.
The PLC Programmable Logic Controller mainly is the co-ordination that solves each parts; as add water, dosing (emulsifying agent) heating, temperature, water level, A case and the B case exchanges; also have the protection and the warning of variable-frequency governor; protections such as the PiD upper limit; also have other alarm and protection, making whole duty is to be in full automatic work.
Advantage of the present utility model: simple in structure, utilize advanced device variable-frequency governor and adjuster PiDPLC control, control is flexible, and oil-saving effect is good, and energy savings is a kind of more perfect heavy oil combustion system.
