Abstract
The utility model relates to an energy-saving device which can be used for recycling the residual heat of industrial steam boilers. A suction end supporting seat and an exhaust end supporting seat are arranged on a pedestal, and a water vapor inlet and a water vapor outlet are respectively arranged on the two supporting seats. A cylinder sleeve is connected between the two supporting seats, a threaded rod is arranged in the cylinder sleeve, and a lining is connected between the threaded rod and the cylinder sleeve. The tail steam and the high temperature condensing water of industrial steam boilers are used in a circulating mode via the rotation of the threaded rod, so the purpose of energy saving is accomplished. The utility model has the advantages of simple structure, high work efficiency, good energy-saving effect and convenient manufacture and use.
Description
The utility model belongs to the pump technical field, is specially adapted to the recovery of industrial steam boiler waste heat.
At present, the feed pump of industrial steam boiler mostly is the multistage centrifugal water pump, and the too high meeting of water temperature in use of this pump makes the vaporization of impeller place, and can produce point corrosion at the impeller position, makes its cisco unity malfunction thereby damage impeller.Therefore the tail vapour of general industry steam boiler and the condensed water of higher temperature are all directly emitted, or reclaim recirculation use after cooling off, and cause this part waste heat to be not used, and cause the waste of the energy.The patent No. is: disclose a kind of reciprocating type energy-saving pump in 93231634.4 the Chinese utility model patent specification, this pump mainly is to be made of parts of appliance such as decelerator, toggle, two-way rams, and its shortcoming one is a complex structure, and inconvenience is installed; The 2nd, owing to adopt the form of reciprocating pump, moving component is many, and be in operation and need overcome its reciprocating inertia, thereby inefficiency, energy-saving effect is poor, and the 3rd, equipment volume is big, and consumable material is many, the production cost height.
The purpose of this utility model is that design is a kind of simple in structure, the steam boiler waste heat recovering energy conserving device of good energy-conserving effect.
The utlity model has a base, suction side bearing and outlet side bearing are installed on base, the suction side bearing is provided with the steam inlet, the outlet side bearing is provided with the steam outlet, be connected with the cylinder sleeve that is communicated with steam inlet and steam outlet respectively between two bearings, screw rod is installed in the cylinder sleeve, is connected with lining between screw rod and the cylinder sleeve.
The utility model is simple in structure, be convenient to make, install, just with and maintenance, and easy break-down not, cost is low, in the course of the work, its inertia loss is little, high efficiency, good energy-conserving effect, more existing reciprocating type energy-saving pump under the situation of same displacement, can reduce power of motor 50%.
Accompanying drawing 1 is the structural representation of the utility model embodiment, and Fig. 2 is the A-A profile of Fig. 1.
Embodiment shown in the accompanying drawing has base (1), suction side bearing (5) and outlet side bearing (2) are installed on it, suction side bearing (5) is provided with steam inlet (7), outlet side bearing (2) is provided with steam outlet (11), be connected with a cylinder sleeve (8) between two bearings, this cylinder sleeve (8) is communicated with steam inlet (7) and steam outlet (11) respectively, its end is installed on the outlet side bearing (2), the other end is installed on the suction side bearing (5), one screw rod (4) is installed in the cylinder sleeve (8), its end is by Hooks coupling universal coupling (6), power transmission shaft (10) links to each other with motor (9), and power transmission shaft (10) stretches out suction side bearing (5) and supports by bearing (12).Be connected with lining (3) between screw rod (4) and the cylinder sleeve (8), this lining (3) is a rubber bushing.
Form sealed chamber one by one between the inner helical surface of the utility model lining and screw surface, in use, when screw rod rotates, screw rod---the volume of first chamber of close suction side increases in the bushing pair, under it and suction side pressure differential effect, high-temperature condensation water and boiler tail vapour just enter first chamber, rotation along with screw rod, this chamber begins sealing and moves to outlet side, disappear at outlet side at last, the suction side can form new chamber again simultaneously, goes round and begins again like this, the continuous supercharging of high-temperature condensation water and boiler tail vapour is discharged, thereby recycled.
Claims (2)
1, a kind of steam boiler waste heat recovering energy conserving device, comprise base (1), it is characterized in that being equipped with on the base (1) suction side bearing (5) and outlet side bearing (2), suction side bearing (5) is provided with steam inlet (7), outlet side bearing (2) is provided with steam outlet (11), be connected with the cylinder sleeve (8) that is communicated with steam inlet (7) and steam outlet (11) respectively between two bearings, screw rod (4) is installed in the cylinder sleeve (8), be connected with lining (3) between screw rod (4) and the cylinder sleeve (8).
2, steam boiler waste heat recovering energy conserving device according to claim 1 is characterized in that said lining (3) is a rubber bushing.
