Abstract
A negative pressure extracting device for a vacuum boiler comprises cooling tanks and a water-collecting tank, wherein a circulatory cooling water inlet is formed in the side surface of the lower part of the corresponding cooling tank; a circulatory cooling water outlet is formed in the side surface of the upper part of the corresponding cooling tank; outlets in the bottom of the cooling tanks are connected to inlets of the water-collecting tank through pipes; and at least one spiral pipe is arranged in the cooling tanks. Heat of high-temperature media in the spiral pipes is taken away by quick circulatory flowing of the circulatory cooling water, and an extracting opening of a vacuum pump is separated from an opening of a condensate water pipe by a steam-water separating partition in the water-collecting tank while condensate water is guided by the steam-water separating partition. Because the temperature of the media is reduced in real time, and the condensate water generated during extracting is well subjected to steam, oil and water separation, the quality and the temperature of oil products of the vacuum pump are guaranteed, and the purpose of continuously extracting negative pressure in real time without stopping is achieved.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1-3, a kind of vacuum boiler extracts negative pressure device, comprises cooling tank 1 and water collect tank 2; The lower side of described cooling tank 1 offers circulating cooling water inlet 3, and upper side offers circulating cooling water out 4; Described cooling tank 1 outlet at bottom is connected to the entrance of water collect tank 2 by pipeline; The inside of described cooling tank 1 is provided with at least one helical pipe 8, and its two ends are connected with the import and export of cooling tank 1 respectively; The inside of described water collect tank 2 is provided with one block of vapour, water is separated dividing plate 9, water collect tank 2 is separated into the cavity that two bottoms communicate, offer water collect tank 2 entrance at the cavity top of vapour, water separation dividing plate 9 side, the side of opposite side cavity offers at least one vacuum pump interface 6; The bottom of described water collect tank 2 has condensate drain outlet 7.The negative pressure extracting mouth of the external vacuum equipment of entrance at cooling tank 1 top.Vacuum equipment is vacuum boiler.Helical pipe 8 is in 30 ° of inclinations angle.The pipeline be connected between cooling tank 1 with water collect tank 2 is provided with stainless steel ball valve 5.The pipeline of stainless steel ball valve 5 and connection each several part all adopts the stainless steel of SS304.
See Fig. 1 and 2, the present invention can arrange the cooling tank that two cover recirculated cooling waters are in series as required, and namely the circulating cooling water out of first group of cooling tank is connected with the entrance of the recirculated cooling water of second group of cooling tank; Simultaneously as required water collect tank can arrange multiple vacuum pump interface, work, to increase work efficiency in order to connect multiple vavuum pump simultaneously; The present invention also can arrange many helical pipes as required in cooling tank.
Originally be that embodiment selects two cover cooling tanks, and in each cooling tank, be provided with two groups of helical pipes, water collect tank is provided with the optimum way of two vacuum pump interface.High-temperature medium enters the helical pipe two cooling tanks from vacuum boiler simultaneously, and helical pipe surrounds by recirculated cooling water, is taken away by high-temperature medium heat in helix tube, thus reach the object of fast cooling by the Rapid Circulation flowing of recirculated cooling water; The condensed water that period produces flows into water collect tank with pipeline, and is separated along vapour, water the bottom that dividing plate concentrates on water collect tank, finally discharges tank body from condensate drain outlet.Use while two groups of vavuum pumps simultaneously, improve operating efficiency, in water collect tank, vapour, water are separated dividing plate and vavuum pump extraction opening and the condensed water mouth of pipe are separated while by condensate water guide, prevent from condensed water being sucked in pump housing vacuum oil product, thus ensure that oil quality and temperature rise normally improve extraction efficiency.Owing to reducing the temperature of medium in real time and the condensed water produced when extracting well having been carried out vapour, oil, water separation; pumping fluid quality and temperature are guaranteed; reach the object of not shutting down continuous drawing negative pressure in real time; make vavuum pump operationally non-maintaining continuous real-time working again; eliminate in original technology the shortcoming needing to shut down, lower the temperature and need arrange special messenger's filter replacement pumping fluid, drastically increase the operating efficiency extracting negative pressure.
