The new device ensures that a boiler furnace does not vary in accompany with the fluctuation of the load of using steam, and eliminates various disadvantage factors generated against the operation of the boiler furnace owing to the load of using the steam, which can cause the boiler furnace to work under the optimum condition; the thermal efficiency and the thermal utilization factor of the boiler furnace are enhanced, and the quality of products is improved; the labor intensity of operators is lightened, and the utility model can be widely used as various corollary equipment of high-pressure steam.

Description

The pressure swing type steam accumulator

Technical field: the utility model relates to regenerative apparatus.

Background technology: at present regenerative apparatus generally is the form accumulation of heat with high-pressure water heating, and its steam pressure of supplying with the user is less than vapour source pressure, and its numerical value can not adjust, so the scope of application is very narrow.In order to address this problem, people have done multiple effort, disclose a key name for No. 95233352 as Chinese patent and be called " steam accumulator that supercharging device is arranged ", introduced a kind of supercharging device, its pressure of steam supply can not adjusted by the needs by the user in a big way by the restriction of vapour source pressure, and the deficiency of existence is can only unidirectional supercharging.Addressing this problem becomes urgent need.

The content of utility model: overcome the deficiencies in the prior art, proposing a kind of pressure of steam supply can be according to the pressure swing type steam accumulator of user's needs.It has a horizontal drum ladle body pressure swing type steam accumulator, body is provided with vapour inlet, secondary vapor outlet, inner pipe arrangement is housed in the body, the termination of inner pipe arrangement links to each other with flange with a vapour inlet, on the inner pipe arrangement several nozzles are housed, the secondary vapor outlet is connected with steam chest by pipeline, vapour inlet tube and secondary vapor outlet pipe are equipped with stop valve and non-return valve respectively, vapour inlet tube and secondary vapor outlet pipe meet at female pipe, are connected with threeway between female pipe and inlet hydraulic pressure automatic valve and the outlet hydraulic pressure automatic valve.The utility model is owing to make inlet upstream pressure (high pressure) and outlet downstream pressure (low pressure) be rated value under the control of inlet hydraulic pressure automatic valve and outlet hydraulic pressure automatic valve, do not change with fluctuation with the vapour load, eliminated owing to load to the various unfavorable factors of boiler operatiopn generation with vapour, make it and under optimum condition, to move, can not occur empty steam discharge is wasted energy simultaneously yet, make boiler thermal output and heat utilization efficiency improve greatly owing to the vapour amount is superfluous; Because steam pressure and temperature parameter are stable, have also improved product quality; Because stable labour intensity to the operator also alleviates greatly.Because the fluctuation that the utility model can balance produces with vapour can also might reduce the quantity of boiler by considering with the average magnitude of vapour duty value to newly-designed therrmodynamic system boiler output to the transformation of legacy system; Because the result of rated load stable operation, significantly reduced boiler plant accident rate, prolonged life-span of boiler, the colleague has also alleviated the pollution of flue dust to environment fully because of burning.

Description of drawings:

Fig. 1 is this utility model front view;

The specific embodiment: as figure, it has a horizontal drum ladle body 1 the pressure swing type steam accumulator, body is provided with vapour inlet 2 one time, secondary vapor outlet 3, inner pipe arrangement is housed in the body, the termination of inner pipe arrangement links to each other with flange with a vapour inlet, on the inner pipe arrangement several nozzles are housed, the secondary vapor outlet by pipeline be connected with steam chest 6, vapour inlet tube and secondary vapor outlet pipe are equipped with stop valve 7 and non-return valve 5 respectively, vapour inlet tube and secondary vapor outlet pipe meet at female pipe 4, are connected with the outlet threeway between female pipe and inlet hydraulic pressure automatic valve 8 and the outlet hydraulic pressure automatic valve 9.

The course of work of this device is: during startup, must store 50% water in the storage heater body, during work, water-filling mostly is 90% of geometric volume most in jar.Water surface top is the vapor space.Boiler is with the stable combustion condition operation of the best, its steam production is not because of changing with the vapour payload, if high pressure is constant with the vapour load, the instantaneous reduction of low-voltage load, then export downstream pressure and improve trend, pressure signal passes to outlet valve behind the outlet valve at this moment, makes it to turn down automatically, thereby the steam flow of the outlet valve of flowing through is reduced.The steam flow of inlet valve is constant because flow through this moment, so tube connector contact place pressure raises, when its pressure is higher than the storage heater internal pressure, unnecessary steam backs down the non-return valve that fills on the pipe line under pressure, and meanwhile, the non-return valve on the heat-releasing pipeline is closed under pressure automatically, equally, low pressure is constant with vapour load, the steam production surplus of boiler then when high pressure reduces with the vapour load, thus make the inlet upstream pressure that trend of rising be arranged.At this moment, pressure signal passes to inlet valve before the inlet valve, and it is opened greatly automatically, and logical vapour amount increases, thereby causes that communication pipe contact place pressure improves, and simultaneously, the non-return valve on the heat-releasing pipeline is closed under pressure automatically.High steam sprays in the water by being installed in intrinsic nozzle, emits the latent heat of vaporization self and condenses, and the temperature of jar interior water is raise.Along with constantly charging into of steam, the temperature of water raises gradually, and the saturation pressure under the relevant temperature also improves thereupon, because of the steam in entering jar all is condensed in the water, so the also rising thereupon of its water level, Here it is storage heater fill thermal process.Otherwise, if when low pressure or high pressure increase with the vapour load, because unable to make ends meet, the pressure at communication pipe place will be lower than the pressure in the tank body, thereby the non-return valve that fills on the pipe line is closed and non-return valve on the heat-releasing pipeline is opened, the jar internal pressure reduces, and superheated water is launch aed surprise attack evaporation rapidly and produced indirect steam, with the deficiency of supplement boiler evaporation capacity for engine, because a part of water evaporates in jar, the water yield reduces, and water level reduces, the exothermic process of Here it is storage heater.When high-low pressure changes simultaneously with vapour load, because the regulating action of two control valves and non-return valve can guarantee that high pressure all is stabilized on the rated pressure with steam pressure with steam pressure and low pressure.
