Abstract
The utility model relates to a low-level water sealing tube device for a steam engine, which is suitable for a steam engine workshop of a power station. The utility model is composed of a low-level cistern 1, a water sealing tube 4, condensers 10, 11, hot water wells 15, 16, a water inlet pipe 3, an air conduit 5, suction pipes 6, 7, and valves 2, 8, 9. The essential technical proposal is that according to the principle that the suction lift of a normally operating turbine steam condenser is about 9 metres, the water sealing tube 4 is installed at the bottom of the low-level cistern 1, water in the water sealing tube 4 is continuously sucked into the hot water wells 15, 16 by the condensers through the suction pipes 6, 7, and thereby, a low level water pump is saved. The utility model has the advantages of simple structure, easy installation, convenient operation, little possibility of damage, and free of maintenance, and is ideal low level water recovering equipment.
Description
In model utility is a kind of device that qualified low level water (demineralized water) is recycled in steam turbine workshop, power station.
At present, in steam turbine workshop, power station, low level water (demineralized water) is through collecting pipe, flow into lower water box, chemically examine qualified low level water, it is standby to squeeze into drain tank through the low level water pump, or squeeze into oxygen-eliminating device and reclaim, this way of recycling is deposited big some shortcomings, and it shows: power consumption is big, the loss of part low level hydro-thermal amount, because low level water pump condition of living in is poor, water pump often is out of order, a large amount of low level current lose when repairing water pump, some air enter oxygen-eliminating device, influence oxygen-eliminating device efficient, shortcomings such as pump impeller cavitation damage.
The purpose of this utility model is: it is little to overcome a kind of investment of above-mentioned shortcoming design, moves simple and reliablely, and energy saving reduces the low level water water seal tubular device of amount of maintenance.
The utility model is achieved in that low level water qualified in the lower water box is flowed in the water seal tube through valve, this water seal tube places than low underground of lower water box, again according to the turbine condenser vacuum, when normal operation, water can be inhaled principle high about 9 meters, through two drinking-water pipes of water seal tube and outlet valve the low level water in the water seal tube respectively in the hot well of two turbine condensers of suction, through low-temperature heater, squeeze into oxygen-eliminating device by multiple pump handle low level water and reclaim again.
The utility model is squeezed into drain tank with the existing low water level pump that uses and is compared, and conservation of power, saves heat, saves low level water, invest for a short time, need not keep in repair, and does not influence except that oxygen effectiveness.
Accompanying drawing is a low water level water water seal tubular device schematic representation
According to above-mentioned accompanying drawing the utility model is described in further detail
Water seal tube 4 is an enclosed shape container among the figure, water seal tube 4 is in the position lower than lower water box 1, water inlet pipe 3 one mouths of pipe and lower water box are connected, another mouth of pipe is installed in the top position in the water seal tube 4, one mouth of pipe of air hose 5 places air, another mouth of pipe is installed in the top position in the water seal tube 4, drinking-water pipe 6,7 a mouth of pipe and condenser 10,11 hot well 15,16 are connected, another mouth of pipe places the lower position in the water seal 4, and the vertical range between each drinking-water pipe two mouth of pipe (connecing hot water well head and water seal nozzle) is more than 10 meters, at water inlet pipe 3 and drinking-water pipe 6, filled respectively valve 2 on 7,8,9. After the qualified low level water in the lower water box 1 flows in the water seal tube 4, low level water in the water seal tube 4 is sucked in the hot well 15,16, again through low-temperature heater 12, by condensate pump 13 by turbine condenser 10,11, low level water is squeezed in the oxygen-eliminating device 14, namely finished the utility model.
Example:
With the low level water in the lower water box 1 by opening valve 2, flow in the high 15 meters water seal tube 4, valve 8,9 open, through drinking-water pipe 6,7, vapour condenser 10,11 with the low level water suction Condenser's Hot Well 15 in the water seal tube 4, in 16, sometimes water seal tube 4 drawdown, but because of vapour condenser can only be taken out height about 9 meters, and the vertical length of each drinking-water pipe is greater than 10 meters, so the mouth of pipe that draws water also is in the low level water drinking-water pipe 6, there is air to enter in 7 never, water can suck Condenser's Hot Well 15 continuously like this, in 16, and then,, low level water is squeezed in the oxygen-eliminating device 14 by rehydration pump 13 through low-temperature heater 12.
Claims (2)
1, a kind of steam turbine low level water water seal tubular device, comprise lower water box 1, water seal tube 4, vapour condenser 10,11, hot well 15,16, intake pipe 3, air duct 5, drinking-water pipe 6,7, valve 2,8,9, it is characterized in that: water seal tube 4 is an enclosed shape container, the water seal tube is in the position lower than lower water box 1, the intake pipe 3 that its top is installed air duct 5 and communicated with lower water box, reach the drinking-water pipe 6,7 that is connected with Condenser's Hot Well 15,16, perpendicular distance is greater than 10 meters between each drinking-water pipe two mouth of pipe.
2, steam turbine low level water water seal tubular device according to claim 1, it is characterized in that: the mouth of pipe that is installed in the drinking-water pipe in the water seal tube places the lower position of water seal tube, the pipe of air duct and the mouth of pipe of intake pipe place top position in the water seal tube, have adorned valve 2,8,9 respectively on intake pipe 3 and the drinking-water pipe 6,7.
