Abstract
The utility model discloses an air cooling unit backpressure structure, including exhaust equipment set up spraying system among the exhaust equipment, this system is including water spray pipeline and atomizing nozzle, atomizing nozzle installs on the water spray pipeline, for the demineralized water in the pipeline of just spraying water. The utility model discloses a set up spraying system in exhaust equipment, solved thermodynamic system's moisturizing problem, suitably reduced the temperature of condensing simultaneously, improved thermodynamic system's economic nature and security. Steam extraction temperature through demineralized water reduction steam turbine improves the unit thermal efficiency.
Description
Technical field
The utility model relates to a kind of Air-cooled Unit back-pressure structure.
Background technology
Air-cooled Unit, when summer operation, causes unit back pressuce to raise because environment temperature is higher, causes the limited ability of unit tape splicing load, and causes larger impact to the safety and economic operation of unit.Mostly the domestic means solved for this kind of phenomenon are to arrange spray equipment on Air-Cooling Island at present simultaneously, spray into the demineralized water after atomization by spray equipment to Air-Cooling Island air cooling blower fan exit and reduce the object that air themperature reaches cooling air cooled fin tube bundle, reduce unit back pressuce.This kind of solution cannot reclaim the demineralized water sprayed in air, causes a large amount of wastes (Air-cooled Unit of 300,000, the water consumption of a day is probably at about 1500 tons) of water resource.
Utility model content
In order to solve the irretrievable problem of atomized water of the high phenomenon of Air-cooled Unit summer operation back pressure and the ejection of Air-Cooling Island spray equipment, the utility model provides a kind of Air-cooled Unit back-pressure structure.
The technical solution of the utility model is: a kind of Air-cooled Unit back-pressure structure, comprise steam exhaust device, in described steam exhaust device, arrange spray system, this spray system comprises water pipeline and atomizer, described atomizer is arranged on described water pipeline, and is demineralized water in water pipeline.
Preferably, described water pipeline is connected with moisturizing pipeline.
Preferably, described moisturizing pipeline is provided with two vaccum stop valves and a non-return valve.
Preferably, described moisturizing pipeline is upper is provided with frequency conversion centrifugal water pump between two vaccum stop valves.
Preferably, described moisturizing pipeline is also provided with flow measurement orifice plate.
The beneficial effects of the utility model: the utility model, by arranging spray system in steam exhaust device, solves the moisturizing problem of therrmodynamic system, suitably reduce condensation water temperature simultaneously, improve economy and the security of therrmodynamic system.Reduced the exhaust temperature of steam turbine by demineralized water, improve generatine set heat efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
In figure: 1. vaccum stop valve, 2 frequency conversion centrifugal water pumps, 3 non-return valves, 4 flow measurement orifice plates, 5 steam exhaust devices, 6 water pipelines, 7 atomizers, 8 moisturizing pipelines.
Detailed description of the invention
By reference to the accompanying drawings the embodiment that the utility model provides is described in further detail:
A kind of Air-cooled Unit back-pressure structure, comprise steam exhaust device, in described steam exhaust device 5, arrange spray system, this spray system comprises water pipeline 6 and atomizer 7, and described atomizer 7 is arranged on described water pipeline 6, and is demineralized water in water pipeline.
As shown in Figure 1, in the present embodiment, water pipeline 6 is connected with moisturizing pipeline 8, described moisturizing pipeline 8 is provided with two vaccum stop valves 1 and a non-return valve 3, described moisturizing pipeline is upper is provided with frequency conversion centrifugal water pump 2 between two vaccum stop valves, and described moisturizing pipeline 8 is also provided with flow measurement orifice plate 4.
The utility model, by arranging spray system in steam exhaust device, solves the moisturizing problem of therrmodynamic system, suitably reduces condensation water temperature simultaneously, improves economy and the security of therrmodynamic system.Reduced the exhaust temperature of steam turbine by demineralized water, improve generatine set heat efficiency.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
