Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of boiler-steam dome safety control, the deficiencies in the prior art can be solved, the data such as liquid level, pressure, steam flow in boiler-steam dome are gathered by controller, boiler-steam dome is regulated in real time, and pass through the peripheral structure of appropriate design liquid level gauge, improve certainty of measurement, enhance the security of boiler operatiopn.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of boiler-steam dome safety control, comprises the liquid level gauge be arranged on boiler-steam dome, pressure gauge and relief valve, the jet chimney of boiler-steam dome is provided with flowmeter and flow control valve, the inlet pipeline of boiler-steam dome is provided with small pump; Also comprise a controller, the input of controller is connected with flowmeter with liquid level gauge, pressure gauge, and the output of controller is connected with small pump with flow control valve; The arranged outside of liquid level gauge has condensation sleeve pipe, and the arranged outside of condensation sleeve pipe has water guide cover, and water guide cover inside is provided with froth breaking net, and froth breaking net is woven by multilayer stainless steel wire and makes.
As preferably, also comprise the observation window of liquid level being arranged on boiler-steam dome side, on rear side of observation window of liquid level, be provided with backlight, backlight is provided with red green optical filter.
As preferably, controller adopts Programmable Logic Controller.
The utility model has following beneficial effect.
The utility model gathers the data such as liquid level, pressure, steam flow in boiler-steam dome by controller, and regulate in real time boiler-steam dome, relief valve can carry out automatically unloading when boiler-steam dome pressure anomaly increases.Steam can be carried out condensation water conservancy diversion by the condensation sleeve pipe outside liquid level gauge and water guide cover, and avoid because steam, on liquid level gauge, condensation occurs, condensed water affects the certainty of measurement of liquid level gauge.Froth breaking net can be removed the foam produced due to boiling, avoids the liquid level gauge caused due to foam to detect the big ups and downs of data.Operations staff can observe actual liquid level by observation window of liquid level, and because ruddiness is different with the refractive index of green glow, the part showing ruddiness in observation window of liquid level is gaseous state, and the part of display green glow is liquid, and the junction of red green color is actual water level.Programmable Logic Controller is stable, and environmental suitability is strong, uses under being adapted at various severe operating mode.
