Steam heat storage device

Abstract

The invention provides a steam heat storage device, which belongs to the technical field of mechanical engineering. The steam heat storage device solves problems that wastage is high when steam is supplied for users in the prior art, heat storage efficiency of an existing steam heat storage device is low, operation and control of the steam heat storage device are inaccurate and the like. The steam heat storage device is arranged between a steam source and a consumed steam input header pipe of a user and comprises a heat storage tank, the heat storage tank is provided with a steam inlet pipe and a steam outlet pipe, the steam inlet pipe is communicated with the steam source by a steam inlet one-way stop return valve, the steam outlet pipe is connected with a steam and water separator, an outlet of the steam and water separator is communicated with the consumed steam input header pipe of the user by a steam outlet one-way stop return valve, the heat storage tank is connected with a warning mechanism, and the warning mechanism can make a warning sound when pressure of steam in the heat storage tank exceeds a first set value and when the pressure of the steam in the heat exchange tank is lower than a second set value. The steam heat storage device not only can store residual steam, but also has the advantages of high heat storage efficiency and accuracy in operation and control.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and relates to a heat storage device, in particular to a steam heat storage device. Background technique [0002] Steam can be used as power and heat energy, and is one of the essential energy sources for factories and enterprises. In the industrial boiler steam supply system, if the steam consumption often fluctuates greatly, it will not only cause the boiler steam pressure and water level to fluctuate up and down, make the boiler operation difficult, but also cause the boiler combustion efficiency to decrease. In the steam supply system Installing a steam heat storage device can not only stabilize the boiler load, improve the operating conditions of the boiler, and not reduce the efficiency of the boiler, but also can adjust the imbalance between the gas supply and steam consumption in a certain steam consumption period, and play a role in "peak shaving". The role of "filling val...

Problems solved by technology

[0004] However, in actual use, the above-mentioned patent still has the following problems: when the steam-water exchange inside the accumulator reaches saturation, if the steam supply to the industrial boiler cannot be stopped in time, the boiler steam pressure and water level will still fluctuate up and down , so that the operation of the boiler is difficult, the combustion efficiency of the boiler is reduced, and the excess steam is wasted; The thermal capacity is low; and due to the unscientific local structure of the heat accumulator, there is unnecessary loss of some heat during the process of steam entering the heat accumulator, which reduces the heat storage efficiency of the heat accumulator
