Description
Technical Field
The utility model belongs to the technical field of industrial boiler supplies vapour system, concretely relates to surplus liquid recovery unit of boiler heat accumulator.
Background
The steam consumption in the steam supply system of the industrial boiler often fluctuates by a large margin, which not only causes the steam pressure and the water level of the boiler to fluctuate up and down, makes the operation of the boiler difficult, but also causes the combustion efficiency of the boiler to be reduced. Under the condition, the heat accumulator is used to effectively stabilize the load of the boiler, improve the running condition of the boiler and avoid the reduction of the efficiency of the boiler. The boiler heat accumulator has two types of variable pressure type and constant pressure type, the working pressure of the variable pressure type heat accumulator changes along with the increase and decrease of the heat storage amount, and the most typical type is a steam heat accumulator. The working pressure of the constant-pressure heat accumulator is constant, and the feed-water heat accumulator is the most commonly used.
Converter exhaust-heat boiler systems mostly adopt variable-pressure steam heat accumulators. When the evaporation capacity of the boiler is larger than the steam consumption, redundant steam enters the heat accumulator to heat the stored water (saturated water) in the heat accumulator, the steam is condensed in the heat accumulator, and the pressure in the heat accumulator rises along with the steam; when the amount of steam used is greater than the evaporation amount of the boiler, the stored water (saturated water) in the heat accumulator boils due to depressurization, and steam is supplied to keep the boiler load constant.
At present, the water content of steam recovery of a converter waste heat boiler system is high, a large amount of soft water (or demineralized water) enters a heat accumulator along with steam, the water level of the heat accumulator is controlled in order to guarantee the heat accumulation effect of the heat accumulator, the large amount of soft water (or demineralized water) is directly discharged, the water treatment operation cost is high, the phenomenon that supply of the soft water (or demineralized water) is urgent occurs, and serious water resource waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a surplus liquid recovery unit of boiler heat accumulator, the purpose reduces the waste of water resource.
In order to realize the purpose, the utility model discloses the technical scheme who takes does: the boiler heat accumulator surplus liquid recovery device comprises a hot water tank, a water inlet gate valve, a hot water recovery pump, a check valve and a water outlet gate valve, wherein the hot water tank is connected with the heat accumulator and used for receiving surplus liquid from the heat accumulator, the water inlet gate valve is connected with the hot water tank, the hot water recovery pump is connected with the water inlet gate valve, the check valve is connected with the hot water recovery pump, and the water outlet gate valve is connected with the check valve.
