The useful technique effect of the utility model is:
Increased overflow pipe, solved when blowdown flow rate is big water in the flash vessel and also can in time discharge, hour had water conservation to be sealed into gas port (outlet valve), avoided pipeline to collaborate in flash vessel at blowdown flow rate.
Because main sewer is directly sent into circulating water pool through pipeline, reduce the working time of arranging pump surely to greatest extent, for enterprise cuts down expenses, be social energy conservation.
Description of drawings
Fig. 1: be the utility model overall schematic.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
The utility model is a kind of periodical blowdown flash vessel, comprises a flash vessel housing 1, and this housing 1 upper end is provided with vapour-discharge tube road 2.The lower end sets out waterpipe 3.Sidewall is provided with inlet channel 4, and this outlet conduit directly inserts circulating water pool, and a by-pass valve control 5 is set on this outlet conduit 3, a water conservation is set on this outlet conduit 3 is sealed into gas port 6, and an outlet valve 7 is set on this air inlet port;
This flash vessel housing sidewall is provided with overflow pipe 8 with respect to the opposite side of inlet channel, and this overflow pipe inserts washing basin 9, and the position of this overflow pipe is lower than inlet channel.
A standby valve 10 is set on this outlet conduit.
This water conservation is sealed into gas port and is arranged between this control valve and the service valve.
This housing sidewall top is provided with screening rain and emits 11, the bottom insulation, and top is not incubated.
These inlet channel both sides are provided with motorless inner air and outer air heat interchanger.In newly-built flash vessel water inlet both sides, increase by two energy-efficient air-cooled coolers.Following air inlet above can a total exhaust opening.Use the interchange of heat tubing of some exactly, certain intervals forms motorless internal-external heat exchange device from bottom to top.It is in order to increase dilatation efficient, to reduce the steam content in the artesian water, improve gravity flow speed, play shortening vapour and coagulate the time, reduce water temperature, reducing the effect of dilatation volume that this motorless internal-external heat exchange device is set.
Its technological process is, waste water gets into flash vessel housings 1 from inlet channel 4, and through gas-water separation, gas makes progress away, discharges through vapour-discharge tube road 2, and water gets into outlet conduit 3 downwards, is delivered directly to circulating water pool, and it is far away that general circulating water pool all leaves flash vessel.
Because the water yield of flash vessel is not constant, its blowdown flow rate does not per hour severally wait to one of percentage at percent zero point with regard to drum, and is bigger when discharging water,
When flow has satisfied not, the water that flash vessel is inner, it can slowly go up up to rising to overflow pipe 8 places, after flowing out through overflow pipe 8, flows to washing basin.Because the bleed off pipe below might be occupied by water, in order not reduce the flash vessel volume, increases equal dilatation amount up.In fact flash vessel pressure inside very little (maximum time be not more than 05 kilogram) because above the vapour-discharge tube road is arranged, following drainage pipe be do not stop to outflow.Generally between 100 degree-200 degree, other temperature at discharging condensate is between the 50-80 degree for drum blowdown temperature, and its pressure mainly is the high hot water molecule of part, the expansion force that the energy in flash vessel produces when fully discharging the effect that reaches gas-water separation.
This washing basin 9 is arranged on the next door of flash vessel.Reach a certain height Deng through washing basin behind the certain hour, line operate is shipped in the prompting of master control alarm computer.Close the by-pass valve control 5 of flash vessel outlet earlier, open again and decide row's pump discharge valve (Na Yitai that will use), start simultaneously and arrange pump 911 or 912 surely, the sewer of washing basin 9 is drawn into circulating water pool.Alarm when being extracted into certain low level, operation are turned off and are decided row's pump and valve-off, open flash vessel by-pass valve control 5 subsequently, recover from stream mode.
The main technical point of the utility model is exactly that outlet conduit 3 also has overflow pipe 8 and water conservation to be sealed into the setting of gas port 6.Because the wastewater flow rate of townhouse flash vessel is a variable number, generally change at the 8-30 ton, it is big that special circumstances are also wanted.If from the too for a short time energy-conserving action that do not have of flow, if too big just possible gas blowby, water conservation is sealed into gas port 6 and avoids this problem.
The utility model is applicable to the energy-conservationization transformation of existing big or small electric power enterprise, and because of enterprise practical conditions is different, its energy-saving effect is also slightly different in transformation.Also be adapted to simultaneously the energy-conservationization design of newly-built electric power enterprise, in newly-built, select normal maximum blowdown flow rate,, so just just use washing basin under special circumstances as from the flow design considerations.
The utility model is an electric power enterprise drainage tail end, arranges the flash vessel energy-conservationization design and renovation planning of pond and circulating water pool extremely on the spot surely.Its main purpose is to practice thrift to arrange the pump electric energy surely, reduces the opening time, for enterprise cuts down expenses, is environmental protection projects of green energy conservation thereby practice thrift social resources.
