Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
One kind arranging flash vessel surely, and as shown in Figure 2 and Figure 3, including inside is divided into upper steaming by demarcation plate 2 by cylinder 1, cylinder 1
Vapour chamber 11 and lower soil chamber 12 are equipped with the gas-liquid separator 3 for being connected to upper vapor chamber 11 and lower soil chamber 12 on demarcation plate 2；
And be provided on upper 11 top of vapor chamber and be connected to upper vapor chamber 11 and extraneous steam (vapor) outlet 111, lower 12 bottom of soil chamber setting
Have and is connected to lower soil chamber 12 and extraneous outlet of sewer 121；In addition it is provided in cylinder 1 and protrudes into the water inlet pipe 4 of lower soil chamber 12,
And lower 12 one end of soil chamber is protruded into integrally formed with cushioning fender 41, if being uniformly provided on 4 side wall of water inlet pipe in water inlet pipe 4
Water outlet 42 in dry, interior water outlet 42 is close to cushioning fender 41.So that the impact force that the water flow of water inlet pipe 4 is injected is mostly by buffering
Baffle 41 is born, i.e., water flow is impacted first to cushioning fender 41, is then shunted again from the interior water outlet 42 close to cushioning fender 41
And the impact force that the water flow for going out, and shunting and going out from interior water outlet 42 has greatly reduces, and reduces the sewerage in water inlet pipe 4
Impact to 1 inner wall of cylinder extends the service life of the utility model.
As shown in figure 3, in cushioning fender 41 towards side in water inlet pipe 4 integrally formed with water conservancy diversion protrusion 6, water conservancy diversion protrusion
6 be polygonal pyramid, and corresponding with interior water outlet 42, i.e. each side of polygonal pyramid corresponds to each interior water outlet 42；Setting
Sewerage in water inlet pipe 4 with greater impact power can be carried out shunting decompression by water conservancy diversion protrusion 6, and respectively to each interior water outlet
Mouth water conservancy diversion, substantially reduces impact of the sewerage to cushioning fender 42.
Meanwhile as shown in figure 3, it being welded with impact-absorbing shell 7 in lower 12 inner wall of soil chamber, impact-absorbing shell 7 is sheathed on water inlet pipe 4
Outside, and its outer diameter be greater than water inlet pipe 4 outer diameter, offer out outlet 71 in 7 side wall of impact-absorbing shell, out outlet 71 is close
Lower 12 inner wall of soil chamber, and towards lower 12 inner wall of soil chamber；So that the water impact projected from interior water outlet 42 is in impact-absorbing shell 7
Then wall flows out again from out outlet 71, further reduces sewerage to the impact force of 1 inner wall of cylinder.Again in out outlet
Wearing plate 8 is welded on the inner wall of 71 corresponding lower soil chambers 12；The wearability of 1 inner wall of cylinder is increased, further
Improve the service life of the utility model.
In addition, passing through throttle valve 9 and changing water inlet pipe 4 as shown in Fig. 2, the water inlet end in water inlet pipe 4 is equipped with throttle valve 9
Blowdown water flow and flow velocity, to reduce crude shock power caused by sewerage.
General cylinder 1 has a permissible working pressure, and when accident discharges water in running, the pressure of cylinder 1 permits much larger than this
Perhaps operating pressure, and in lower soil chamber 12 sewerage vaporization, dilatation, very big impact is caused to 1 inner wall of cylinder；Such as Fig. 1
It is shown, therefore the lateral wall in lower soil chamber 12 is equipped with relief valve 10, so that when pressure is excessive, it will be extra by relief valve 10
Pressure discharge, cause to impact to avoid to 1 inner wall of cylinder.
As shown in figure 4, being equipped with the pressure samples pipe 13 protruded into lower soil chamber 12, the pressure samples in 1 side wall of cylinder
Pipe 13 is stainless steel tube, avoids that generation internal corrosion is used for a long time, and be provided with pressure gauge 14, pressure on pressure samples pipe 13
Meter 14 is connected to pressure samples pipe 13 and is located at 1 external position of cylinder；Worker is clearly known in lower soil chamber 12
Pressure.
When boiler needs a large amount of blowdowns, only to be discharged by outlet of sewer 121, efficiency is too slow, as shown in figure 4, therefore
Pipe 15 by blowdown are also communicated in lower 12 bottom of soil chamber, pipe 15 is higher than outlet of sewer 121 in the link position of cylinder 1 by blowdown
In the link position of cylinder 1, pipe 15 is equipped with bypass valve 18 by blowdown, and switch valve 19 is equipped on outlet of sewer 121；To
Blowdown speed is increased, the contaminant removal effectiveness of boiler is improved.
As shown in figure 4, being equipped with liquid level emasuring device 16 on lower 12 lateral wall of soil chamber, which is
Magnetic double level gauge, so that worker clearly knows the remaining waste heat sewage quantity in lower soil chamber 12.
As shown in Figure 1 and Figure 2, cylinder 1 is additionally provided with heat-exchange tube 17, and the heat-exchange tube 17 runs through the upper vapor chamber
11 with lower soil chamber 12, and 17 upper end liquid outlet of heat-exchange tube stretches out cylinder 1 out of upper vapor chamber 11,17 lower end of heat-exchange tube into
Liquid mouth stretches out cylinder 1 out of lower soil chamber 12, and heat-exchange tube 17 is in coil arrangement in cylinder 1, increases the contact with medium
Area；The heat of medium in upper vapor chamber 11 and lower soil chamber 12 can be efficiently used by heat-exchange tube 17, simultaneously
The processing cost of high temperature sewage can be reduced again.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
