Description
Technical Field
The utility model relates to the technical field of boiler safety detection, in particular to a drum water-calling device.
Background
The water level gauge is an indispensable safety accessory in the operation of the boiler, and is mainly used for judging whether the drum is lack of water or full of water when the water level of the boiler is regulated and the boiler is in an accident state, so as to assist operators to take corresponding measures. The on-site display water level gauge is the most common water level gauge of the boiler, but the upper communicating pipe and the lower communicating pipe are not connected to the real top and the bottom of the steam drum under the limit of installation conditions, and the water level of the steam drum cannot be completely displayed, so that the actual water level of the steam drum cannot be displayed when the steam drum is full of water or is lack of water, and the water level condition needs to be judged by calling water so as to take measures.
Because the water volume of the high-parameter large-capacity boiler drum is relatively small, water in the drum can be evaporated to dryness or fully to an impermissible degree in a short time, and the elevation of the drum is very high, an operator runs to the drum to judge the severity of water shortage or fully water by a water calling method, so that the condition that when the water level gauge indicates water shortage or fully water in operation, the operator determines whether to stop the furnace or not after judging the severity by the water calling method, and the emergency stop the furnace and judge the severity of water shortage or fully water by the water calling method is provided, but the user is greatly influenced by the supply of the boiler to the user, the production and living needs of the user terminal are influenced, and even the user terminal is stopped.
The existing water calling method comprises the following steps:
(1) Opening a water drain valve, and if the water level in the water level meter drops, slightly filling water; otherwise, continuing steam-water co-flushing, and then closing the water drain valve;
(2) Closing the steam side valve, and if the water level in the water level gauge rises, slightly lacking water;
(3) If the water level in the step (2) does not rise, slowly opening a water drain valve, and if the water level in the water level meter drops, severely filling water;
(4) If no water level in the step (3) is reduced, the water is seriously deficient;
(5) When a certain state is determined, the operations should be repeated in order to confirm correctness.
In the water-pumping method, although the steam side valve is closed and the water drain valve is opened, the water side valve is not closed, and the water side valve enables the steam drum to be communicated with the water level gauge, which is equivalent to the water supply of the steam drum, if the water level is in a serious water-pumping state, the water level in the steam drum is difficult to be reduced to the height which can be displayed in the water level gauge in a short time because the water discharge amount of the water drain valve in unit time and the water amount exceeding the top of the water level gauge in the steam drum are not in an order of magnitude, so that the judging time of the serious water-pumping state is greatly prolonged, and the detection and elimination efficiency of accidents are influenced.
