Description
Technical field
The present invention relates to a kind of waterproof method for controlling impact of saturated vapor generating equipment, belong to mechanical monitoring field.
Background technology
As iron and steel enterprise's energy-saving and emission-reduction work is constantly taped the latent power deeply, the vapour such as palletizing shaft furnace, steelmaking converter, heater for rolling steel
The low-quality saturated vapor for changing cooling system production is also used to generate electricity, and the engine of selection is generally that steam turbine and screw rod turbine are swollen
Swollen machine, existing engine is waste heat, complementary energy recovery due to evaporated cooling system, stopped production by host's processing line Batch Process, plan,
The condition limitation such as failure stopping production, the saturated vapour pressure produced, temperature, flowed fluctuation are larger, in addition the pipeline of long range
Conveying, the steam parameter into engine is it is difficult to ensure that design load, or even there is the potential safety hazard of water slug.These utilize low product
The engine that matter saturated vapor generates electricity, mostly unattended equipment lacks perfect monitoring method, is simply supervised by operations staff
Control steam inlet condition compares the saturated-steam temperature pressure table of comparisons again, the purpose intervened in advance, controlled in time is not had at all, often
Cause serious accident.
The content of the invention
The technical problems to be solved by the invention are that the shortcoming for overcoming prior art can give warning in advance simultaneously there is provided one kind
The control method of the anti-water slug of saturated vapor generating equipment is protected in time.
In order to solve the above technical problems, the present invention provides a kind of waterproof impulsive control side of saturated vapor generating equipment
Method, including data acquisition equipment, data processing equipment and control warning device, step are as follows：
S1, data processing equipment are default to alarm with saturated-steam temperature and the standard saturation curve A of pressure correlation, water slug
Curve B and water slug shutdown curve C；
The number of the temperature and pressure of air inlet before S2, the engine machine of data acquisition equipment collection saturated vapor generating equipment
According to, and data processing equipment is transferred data to, data processing equipment sets up operating point O before machine in a coordinate system；
The position of operating point 0 before S3, data processing equipment judgement machine：If operating point 0 is located at standard saturation curve A before machine
Between water slug alarm curve B, then data processing equipment transmits " normal " signal to warning device is controlled, and controls warning device
Control engine does as usual running；If operating point 0 is located at water slug and alarmed between curve B and water slug shutdown curve C lines before machine,
Then data processing equipment transmits Alarm signal to warning device is controlled, and control warning device sends alarm signal；If before machine
Operating point 0 is located at outside water slug shutdown curve C, then data processing equipment transmits signal for "cut motor" to warning device is controlled, and controls
Warning device controls engine forced stoppage.
The technical scheme that further limits of the present invention is：In step S1, data processing equipment is preset and saturated-steam temperature
Standard saturation curve A, water slug alarm curve B and water slug shutdown curve C method with pressure correlation are：
S1, the data of the saturated-steam temperature of data acquisition equipment collection standard and pressure are simultaneously transferred data at data
Equipment is managed, data processing equipment carries out processing drafting standard saturation curve A to the data of reception；
S2, it is defined by standard saturation curve A, temperature reduces by 3 degree of data simultaneously under data acquisition equipment collection uniform pressure
Data processing equipment is transferred data to, data processing equipment carries out processing to the data of reception and draws water slug alarming line B；
S3, it is defined by standard saturation curve A, temperature reduces by 5 degree of data simultaneously under data acquisition equipment collection uniform pressure
Data processing equipment is transferred data to, data processing equipment carries out processing to the data of reception and draws water slug shutdown line C.
Further, data processing equipment includes display device, and display device shows standard saturation curve A, water slug report
Operating point 0 before alert curve B, water slug shutdown curve C and machine.
Further, the temperature and pressure rectangular coordinate system that the coordinate in display device is.
Further, in step S3, when controlling warning device to send alarm signal, vapour source is electronic before chain opening machine puts
Valve is dissipated, reduction vapour source pressure makes operating point return to water slug alarm more than curve B, prevents operating mode from continuing to deteriorate.
The beneficial effects of the invention are as follows：The present invention utilizes patterned display mode to realize and supervised quickly, effectively, in real time
Control；This method has the advantages that to intervene in advance, controlled in time, can effectively protect unit in the case of severe；This method
Design is dexterous, operation is simple, realizability is strong.
