The de-salting water tank and the deaerator are communicated by a pipe, and the deaerator and the boiler are communicated by a pipe. The pipe between the de-salting water tank and the deaerator is communicated with a clinker cooler, which is communicated with the pipe of the de-salting water tank. The clinker cooler is communicated with the pipe of the deaerator. On the pipe between the clinker cooler and the deaerator, a steam-trap tank is provided. The steam-trap tank is communicated with the pipe of the boiler. The pipe between the steam-trap tank and the boiler is provided with a fixed manifold. The utility model not only saves water resource, reduces production cost, but also makes the water temperature on the boiler meet production, and is of high value for utilization and popularization.
Description
Technical field
The utility model relates to a kind of heat energy, water circulation comprehensive use device, specifically, relates to a kind of heat integration device with condensed water cooling lime-ash.
Background technology
How better utilization heat energy and water are the problems that a lot of thermal power plants all will be faced.At present, many thermal power plants existing problems mostly are: the one, and cold slag machine makes and is cooled with circulating water, and backwater enters trench, causes a large amount of wastes of water resource.The 2nd, boiler water filling does not meet design temperature, and boiler water filling must use higher-pressure deaerator to handle the deaerated water that the back surpasses 150 ℃.The 3rd, cold slag machine backwater amount is big, and deaerator level is regulated difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, effective conserve water resource, not only makes the boiler water filling temperature meet design temperature, and makes deaerator level regulate easier heat integration device with condensed water cooling lime-ash.
This practical technical scheme is: with the heat integration device of condensed water cooling lime-ash, comprise sweet-water tank, oxygen-eliminating device, boiler, pipeline is communicated with between described sweet-water tank and the oxygen-eliminating device, pipeline is communicated with between described oxygen-eliminating device and the boiler, it is characterized in that: the pipeline between described sweet-water tank and the oxygen-eliminating device is communicated with cold slag machine, described cold slag machine is communicated with the sweet-water tank pipeline, cold slag machine is communicated with the oxygen-eliminating device pipeline, pipeline between cold slag machine and the oxygen-eliminating device is provided with drain tank, described drain tank is communicated with boiler tubing, and the pipeline between described drain tank and the boiler is provided with the female pipe of fixed row.
Below be the improvement of technical solutions of the utility model:
Pipeline is communicated with high-pressure heater between described oxygen-eliminating device and the boiler.
Beneficial effect: the utility model adopts said structure, has the following advantages:
(1) cool off by cold slag machine all being changed into demineralized water, and backwater is changed to sweet-water tank, effectively the conserve water resource has reduced production cost.
(2) by cold slag machine lime-ash heating demineralized water, the demineralized water temperature is reached more than 50 ℃, save the steam-heated hear rate and the steam consumption like this.
(3) arrange female pipe surely with boiler and link to each other by cold slag machine being returned a road of oxygen-eliminating device, form the complete last water route line of a cover, water on the realization black furnace meets the requirement of boiler water filling fully.Utilize drain tank to water on the high-temperature high-pressure boiler, solve the problem of boiler water filling overtemperature, greatly reduce the possibility that causes piping high vibration damage equipments such as economizer because of the water overtemperature.
(4) effectively regulate cold slag machine backwater amount, easier adjusting deaerator level.
The utility model is simple in structure, efficient is high, not only can effectively reduce production costs, and can make the boiler water filling temperature meet production requirement, has higher use value and promotional value.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment, as shown in drawings, heat integration device with condensed water cooling lime-ash, comprise sweet-water tank, oxygen-eliminating device, high-pressure heater, boiler, be provided with pipeline between described sweet-water tank and the oxygen-eliminating device, pipeline is communicated with between described oxygen-eliminating device and the high-pressure heater, pipeline is communicated with between described high-pressure heater and the boiler, be communicated with pipeline between described boiler and the oxygen-eliminating device, described sweet-water tank is provided with cold slag machine, described cold slag machine is provided with drain tank, and described drain tank pipeline connects oxygen-eliminating device, is provided with the female pipe of fixed row between described drain tank and the boiler.
Know-why:
Present cold slag machine backwater is divided into two-way, and one the road to sweet-water tank, and one the road to drain tank.Go up water from drain tank, temperature can be above 70 ℃.Cold slag machine cooling water pipeline connects one and switches valve, and the pipeline backwater only switches to drain tank to sweet-water tank when water quality is defective.
Claims (2)
1, cools off the heat integration device of lime-ash with condensed water, comprise sweet-water tank, oxygen-eliminating device, boiler, pipeline is communicated with between described sweet-water tank and the oxygen-eliminating device, pipeline is communicated with between described oxygen-eliminating device and the boiler, it is characterized in that: the pipeline between described sweet-water tank and the oxygen-eliminating device is communicated with cold slag machine, described cold slag machine is communicated with the sweet-water tank pipeline, cold slag machine is communicated with the oxygen-eliminating device pipeline, pipeline between cold slag machine and the oxygen-eliminating device is provided with drain tank, described drain tank is communicated with boiler tubing, and the pipeline between described drain tank and the boiler is provided with the female pipe of fixed row.
