Description
Technical field
The utility model relates to the boiler for preparing high pressure superheated steam, and particularly the high pressure superheated steam boiler flue has soot cleaning system.Can be applied to steam-electric power, oven dry, heat supply, and technical field such as oil field steam-assisted recovery.
Background technology
At present, the preparation high pressure superheated steam generally is to adopt the secondary steam heating means are obtained.As Chinese patent application number is 03226903 and 02145063 etc.Existing superheated vapour heating-furnace generally lays particular emphasis on the utilization of heat energy, improves the thermal efficiency, the energy savings aspect.For superheater inwall salt scale coagulation problem, fail to be well solved.When the superheater salt scale coagulation is serious, can cause boiler overheating pipe explosion accident.In addition, the fuel-firing gas-firing superheated vapour heating-furnace, after the long-time running, dust deposit in flue is serious, and is difficult to remove, and influences heating furnace operation heat exchange efficiency, improves exhaust gas temperature, causes heat greatly to lose, and environment is caused seriously influence.Dust deposit in flue, the flue gas circulation area reduces, the increase of the spontaneous draught capacity of flue gas is much smaller than the increase of dust stratification resistance, smooth and easy in order to guarantee to discharge fume, must strengthen power of fan, increase power consumption, thereby additionally increase operation and maintenance cost, improve the back current cost, and do not meet that country repeats injunctions, the policy of energy-saving and emission-reduction.The utility model is primarily aimed at these situations, in the past on the basis of superheated vapour heating-furnace, based on theory, base oneself upon reality, the response policy has designed the brand-new practical ash blowing and cleaning system of a cover, can very solve a series of problems that dust stratification brings effectively and fundamentally.
Summary of the invention
The purpose of this utility model provides a kind of fuel gas superheated vapour generator with ash blowing and cleaning system, can guarantee the smooth and easy circulation and the high efficient heat exchanging of heating furnace air and gas system.The fuel gas superheated vapour generator design of this band ash blowing and cleaning system has ash blowing and cleaning system; comprehensively in conjunction with existing boiler technology; take into full account various physical conditions; merged multinomial new technology well; in body of heater thermal insulation layer inboard the stainless steel protection inner core is set, in case damage thermal insulation layer during ash blowing and cleaning.
The utility model is that the technical scheme that its technical problem of solution is taked is: the fuel gas superheated vapour generator of band ash blowing and cleaning system is mainly by burner; body of heater; chimney and safety valve are formed; refractory insulating layer is arranged in the body of heater; there is stainless protection layer the thermal insulation layer inboard; it is characterized in that: the front end of body of heater is symmetrically fixed with preceding blowing pipe; the rear end of body of heater is fixed with the back blowing pipe; bottom of furnace body has cleaning door; radiant tube in the body of heater is inside and outside two-layer coil arrangement; distance between outer coil pipe and the inner coil pipe is between 100～500 millimeters; inner coil pipe is a superheater, and outer coil pipe is an evaporimeter.Two-layer coil pipe has import and outlet and symmetry to be fixed on the rear end of body of heater respectively.
Be connected high pressure blower with the back on the blowing pipe at preceding blowing pipe, the time opening gate, pressure-air is by preceding blowing pipe and back blowing pipe, and externally the cigarette ash on coil pipe and the inner coil pipe outer wall is cleared up.The ash blowing and cleaning system structure has tangible novelty and very strong practicality, blows ash mouthful symmetric design in the body of heater front and back end, and cleaning door designs at bottom of furnace body.According to boiler operation situation, can regularly purge deashing to flue system handles, guarantee that two, three backhaul flue streams are clear and coherent smooth, reduce flue circulation drag losses, reduce blower fan and exert oneself, clear disk tube wall face cigarette ash accumulation horizon, reduce the heat convection thermal resistance, reach the effect of enhanced heat exchange, thereby improve heat transfer efficiency, reduce exhaust gas temperature, improve rate of energy.Adopt the ash blowing and cleaning system innovative technology, must consider the protection of thermal insulation layer, therefore, this superheated vapour heating-furnace is provided with the stainless steel inner core in the thermal insulation layer inboard, prevents to blow ash and damages thermal insulation layer.
In order to regulate temperature in the body of heater, prevention is too high near the inner coil pipe temperature of burner, and there is the compound heat-insulation layer inboard near inner coil pipe, and the thickness of compound heat-insulation layer is 10～30 millimeters, and length is 500～1200 millimeters.
The beneficial effects of the utility model are: the fuel gas superheated vapour generator of the utility model band ash blowing and cleaning system, can regularly purge deashing to boiler two, three backhaul flue gas flow channels effectively, guarantee that flue is in cleaner state for a long time, reduce the flow of flue gas drag losses, reduce blower fan and exert oneself, guarantee good heat exchange environment, improve heat exchange efficiency, reduce the boiler attendance expense, improved effective utilization rate of energy.Popularization of the present utility model saves a large amount of energy will for country, brings harmonious looks for society and environment.
