The system is characterized in that the water replenishing pipe of the water jet box is connected with purified water equipment; the water replenishing pipe on the condenser is set as a suction pipe which is inserted below the liquid level of the water jet box; and the condenser absorbs purified water of the water jet box on the basis of own negative pressure effect. According to the energy-saving condenser vacuum-pumping system, the replenished water of the water jet box is changed from raw water into purified water, the water quality is improved, and the service lives of the water jet pump, the vapor extractor and other equipment are prolonged; and the water jet box does not discharge water directly any longer, and by virtue of vacuum of the condenser, water to be discharged is collected into the condenser and used as boiler replenished water directly instead of original replenished water, so that the water source is saved, and the heat is recycled.
Description
Technical field
The utility model relates to METHOD FOR TURBOGENERATOR SET, relates in particular to the condenser pumped vacuum systems.
Background technology
At present, the condenser of METHOD FOR TURBOGENERATOR SET need keep the vacuum near 0.1MPa, therefore all is furnished with pumped vacuum systems, and the air in the condenser is extracted out by pumped vacuum systems.Pumped vacuum systems as shown in Figure 1, formed by jetting case 7, water-jet pump 6, discharge jet 8, jetting vapor extractor 1, exhaust tube 2, exhaust tube 2 is connected on the condenser 3, be connected with filling pipe 6 on the jetting case 7, this filling pipe 6 connects former water supply equipment (do not pass through purified treatment, the water that water quality is relatively poor); Also be provided with filling pipe 4 on the condenser 3, this filling pipe 4 directly connects the pure water supply equipment, and pure water is the pure water that reaches the boiler standard.Because the air of extracting out has certain heat, the coolant-temperature gage in the jetting case will rise, so will control water temperature by the mode of limit moisturizing, the direct draining in limit, institute moisturizing source and carry heat and directly drain in the jetting case is so cause significant wastage to water source, the energy.Because condenser is also established pure water Bu Give water source separately, cause two cover systems to supply water, also wasted the energy.
Summary of the invention
In order to overcome the deficiency of existing condenser pumped vacuum systems, the utility model is transformed existing vacuum system, designs a kind of energy-saving condenser pumped vacuum systems.
Technical scheme is, a kind of energy-saving condenser pumped vacuum systems, be made up of jetting case, water-jet pump, discharge jet, jetting vapor extractor and exhaust tube, exhaust tube is connected on the condenser, is connected with filling pipe on the jetting case, condenser is connected with filling pipe, it is characterized in that the filling pipe of jetting case connects pure water equipment, the filling pipe on the condenser is made as suction hose, suction hose inserts below the liquid level of jetting case, and condenser is by the pure water of the suction function absorption jetting case of self.
In order to regulate water level and pump-out automatically, close the water route when water level is low automatically, the vacuum of protection condenser is equipped with fluid level control valve in the jetting case, and the suction hose of condenser is connected on the fluid level control valve.
The preferable configuration of above-mentioned fluid level control valve is, it comprises a cylinder valve, and the valve body upper end is provided with valve gap, valve body lower portion week side be provided with water inlet; Be provided with center-pole in the valve pocket, valve pocket middle part and bottom are respectively equipped with dummy piston and piston type main valve plug, dummy piston and piston type main valve plug are separately fixed on the center-pole, contact position below center-pole and the piston type main valve plug is provided with the primary seal body, center-pole exposes the back from valve gap and connects upper floating ball, and the place, aperture that center-pole contacts with valve gap is provided with secondary seal, and valve body lower end is provided with delivery port, valve pocket on the dummy piston constitutes the balance hydroecium, is communicated with balance pipe between balance hydroecium and the delivery port.
Because whole valve body is installed in below the water surface, selects for use material to be resistant material.
Good effect of the present utility model is:
1, the moisturizing of jetting case changes pure water into by former water, and water correction is beneficial to service life of equipment such as water-jet pump, vapor extractor; The draining of jetting case is no longer directly discharged, but the water that utilizes the vacuum of condenser will need to discharge takes in condenser, directly as boiler replenishing water, replaces original moisturizing, saves the water source, the recovery heat; Turbo-generator Set with a 25MW is example:
Reclaim the water yield: the recovery water yield hourly is approximately 5～7 cubes, use this transformations after, the annual water yield that reclaims surpasses 40000 cubes, by 5 yuan of calculating of every cube of water comprehensive cost, year is cost-saved more than 200,000 yuan.
Reclaim heat: generally more than 10 degree, 1 year recyclable heat of 40000 cubes of water is the temperature difference of feed and bleed: 4.18 * 10
6J/m
3* 40000m
3=1.672 * 10
11J ≈ 170GJ sells 70 yuan/GJ of caloric value lattice by power plant and calculates, and can increase receipts every year: 70 * 170 ≈ 20000 (unit).
At present, national most condensers adopt similar jetting vapor extractor system, if all carry out this transformation, benefit is huge.
2, the jetting steam bleeding system changes pure water into by former water, and water correction is beneficial to service life of equipment such as water-jet pump, vapor extractor, saves recondition expense, alleviates labor strength.
3, because pure water is lower than former coolant-temperature gage, give jetting case cool effect better; After adding the vacuum type fluid level control valve, can control water absorption and jetting case liquid level automatically, close automatically during lack of water, prevent from destroying vacuum.
4, because the fluid level control valve effect can be regulated water level and water absorption automatically, close the water route when water level is low automatically, the vacuum of protection condenser.
