Description
Technical field
The utility model relates to the blowdown cooling device on the high temperature frame of water vapor sampling equipment in thermal power plant.
Background technology
In fuel-burning power plant, actuating medium---the quality of High Temperature High Pressure water and steam directly affects the security performance of heat engine.Therefore, on-line continuous analysis is carried out to high-temperature high pressure water and steam sampling, monitoring is indispensable.If it is unpractical for directly High Temperature High Pressure water and steam being introduced in-line meter, usually first the temperature of water and steam, pressure, flow must be down to research and application instrument normally to work under the condition that allows and carry out, namely water and steam sampling equipment be these working equipments.The high temperature frame of water and steam sampling equipment is provided with blowoff line, this blowoff line mainly gets rid of first water (steam) when water and steam sampling equipment starts at every turn, this is because in the situations such as heat power plant boiler maintenance down or long-time interruption of work, the sample water (steam) of drawing from heat power plant boiler is very dirty, sampling system can not be introduced, these water (steam) will emit by the blowoff line on high temperature frame, if directly discharge and must have very large danger, therefore existing blowoff line is all connected to blowdown cooling device, just discharge after cooling.
In prior art, the conventional disc tubular heat exchanger that blowdown cooling device just adopts, though it is quite high to seem heat exchange efficiency, but finds that it exists following defect in using in practice:
1, when blowdown is initial, because the pressure of blowdown is comparatively large, high-temperature steam shape sewage may directly be gone out, and there is potential safety hazard;
2, want bending to there is STRESS VARIATION when coil pipe makes, easily ftracture, affect serviceable life;
3, the sewage of blowdown has certain pressure, and such effluent stream, through fine coil pipe, can bring very large vibration, easily causes welding junction to rupture, also affects serviceable life.
Summary of the invention
The purpose of this utility model is to provide with presetting system blowdown cooling device on a kind of high temperature frame, with solve prior art exist blowdown initial time high-temperature steam shape sewage may directly go out, there is the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is: with presetting system blowdown cooling device on a kind of high temperature frame, comprise outer tank body and be arranged on the interior tank body in outer tank body, space between outer tank body and interior tank body is as cooling water cavity, the bottom of outer tank body is provided with cooling water inlet, and its top is provided with coolant outlet; The inner chamber of described interior tank body is as high-temperature medium chamber, the top of interior tank body is connected to the high-temperature medium induction pipe that guides outer tank body outside into, the bottom of interior tank body is connected to the high-temperature medium outlet that guides outer tank body outside into, this high-temperature medium outlet has an inverted U-shaped bending section, and the peak of this inverted U-shaped bending section is higher than the junction of interior tank body and high-temperature medium induction pipe.
In such scheme, the inverted U-shaped bending section of described high-temperature medium outlet is positioned at outer tank body inside.
The utility model design concept and effect are:
The utility model adopts inside and outside nested tank body, particularly the peak of the inverted U-shaped bending section of high-temperature medium outlet is designed higher than the junction of interior tank body and high-temperature medium induction pipe, interior tank inner chamber (high-temperature medium chamber) can be prestored the water that last time, blowdown stayed, and be a full tank, in stopping process, these water can be down to the temperature close with chilled water naturally, thus when blowdown is initial, because interior tank inner chamber (high-temperature medium chamber) prestores cold water, just may discharge from high-temperature medium outlet after the sewage of high temperature needs to lower the temperature with the cold water mix prestored in interior tank body after high-temperature medium induction pipe enters, thus the generation of the situation effectively avoiding the sewage of high-temperature steam shape directly to go out.Further, compared with existing tube exchanger, the utility model makes more convenient, and cost of manufacture is lower, and vibration during work is also smaller, can be described as the use occasion being more appropriate to blowdown on water vapor sampling equipment in thermal power plant high temperature frame.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
With presetting system blowdown cooling device on a kind of high temperature frame, the interior tank body 2 comprising outer tank body 1 and be arranged in outer tank body 1, space between outer tank body 1 and interior tank body 2 is as cooling water cavity 3, and the bottom of outer tank body 1 is provided with cooling water inlet 4, and its top is provided with coolant outlet 5.The inner chamber of described interior tank body 2 is as high-temperature medium chamber 6, the top of interior tank body 2 is connected to one and guides high-temperature medium induction pipe 7 outside outer tank body 1 into, the bottom of interior tank body 2 is connected to one and guides high-temperature medium outlet 8 outside outer tank body 1 into, this high-temperature medium outlet 8 has an inverted U-shaped bending section 9, and the peak of this inverted U-shaped bending section 9 is higher than the junction of interior tank body 2 with high-temperature medium induction pipe 7.The inverted U-shaped bending section 9 of described high-temperature medium outlet 8 is positioned at outer tank body 1 inside.
During the present embodiment work, interior tank inner chamber (high-temperature medium chamber 6) can prestore the water that last time, blowdown stayed; and be a full tank; in stopping process, these water can be down to the temperature close with chilled water naturally; thus when blowdown is initial; because interior tank inner chamber (high-temperature medium chamber 6) prestores cold water; just may discharge from high-temperature medium outlet 8 after the sewage of high temperature needs to lower the temperature with the cold water mix prestored in interior tank body after high-temperature medium induction pipe 7 enters, thus the situation effectively avoiding the sewage of high-temperature steam shape directly to go out occurs.Further, the utility model is easy to make, and cost of manufacture is low, and vibration during work is also smaller, can be described as the use occasion of most suitable blowdown on water vapor sampling equipment in thermal power plant high temperature frame.
The accompanying drawing of the present embodiment is citing signal, inverted U-shaped bending section 9 set-up mode of its high-temperature medium outlet 8 can change to some extent, not as diagram, U-shaped bending section 9 and interior tank body 2 in one plane can be arranged side by side, and the periphery of the U-shaped bending section 9 of high-temperature medium outlet 8 around interior tank body 2 is established, so just can save a little space, under same outer tank body 1 size, interior tank body 2 is strengthened, to increase the water-holding quantity of interior tank body 2.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
