Abstract
The utility model relates to equipment for treating transformer oil in the power industry, in particular to a steam heating system for heating transformer oil in a vacuum oil filter. The steam heating system of the vacuum oil filter is characterized in that steam is in heat exchange with circulation water via a heat exchanger I, and the circulation water is in heat exchange with the oil of the vacuum oil filter via a heat exchanger II. The steam heating system of the vacuum oil filter is fast in heating speed and high in heat transfer coefficient, damage to the transformer oil is effectively reduced, output power of equipment is greatly reduced, and energy is saved effectively. In addition, as temperature rise of the transformer oil is more stable, local heating is avoided, and damage of oil products due to the fact that the transformer oil is over hot is also avoided.
Description
Technical field
The utility model relates to the equipment of in the power industry transformer oil being handled, and is specifically related to a kind of steam-heating system that transformer oil in the vacuum oil-filter is heated.
Background technology
Along with the develop rapidly of power industry, electric pressure, the capacity of domestic power transformer constantly increase, and be also more and more stricter for the equipment requirements of oil processing; At present; Transformer oil is heated, adopt contact or electrical heating type mostly, the contact heating causes damage to oil easily; Electrical heating type starts moment, and oily temperature rises sharply, and local heating is prone to cause the transformer oil cracking; In addition, it is big more that transformer oil is handled flow, and the consumed power of electric heater is just big more.
The utility model content
To the technical problem that exists in the prior art, the purpose of the utility model is to provide a kind of vacuum oil-filter steam-heating system through intermediary indirect transformer oil.
The technical scheme that the utility model adopts is following:
The vacuum oil-filter steam-heating system is characterized in that, steam carries out heat exchange through heat exchanger I and recirculated water, and recirculated water carries out heat exchange through the oil of heat exchanger II and vacuum oil-filter again.
Comparatively perfect is,
Steam gets into heat exchanger I through steam inlet tube, break valve, filter, Pneumatic/electric control valve and Pressure gauge successively, and the condensed water that forms after the process heat exchanger I heat exchange goes out pipe through filter, floating ball hydrophobic water valve, check-valves, ball valve and condensed water successively and leaves.
Recirculated water gets into heat exchanger II through temp probe, pressure sensor, expansion drum, Pressure gauge, relief valve and ball valve after leaving heat exchanger I successively, returns heat exchanger I again through ball valve, coarse filter and water pump successively through the recirculated water after the heat exchanger II heat exchange.
In order to prevent the loss of recirculated water; The utility model vapour system also is provided with the recirculated water replenishment system; Partial condensation water through check-valves gets into water pot through electrical ball valve; Part water in the water pot flows into circulating water line through coarse filter, water pump and check-valves successively, and gets among the heat exchanger I, and said water pot is equipped with ball valve and liquid level sensor.
The utility model vacuum oil-filter steam-heating system is utilized the heat exchange principle, uses intermediary indirect oil; Steam is through heat exchanger I Heating Cyclic water; Recirculated water is again through heat exchanger II heated oils, and recirculated water returns heat exchanger I and repeated heating by steam, forms the indirect process to oil; Improve the oil temperature, to reach the production demand.Steam forms Water in Condenser after by heat exchange, and a part is directly got rid of, and another one gets into water circulation system again, thereby is water circulation system compensation institute water requirement.
Compared with prior art, the utility model firing rate is fast, and thermal transmission coefficient is high, effectively reduces the damage to transformer oil, greatly reduces the power output of equipment, has practiced thrift the energy effectively.In addition,, avoided localized heating, and the overheated oil product that causes of transformer oil damages because the intensification of transformer oil is more stable.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the system architecture diagram of the utility model vacuum oil-filter steam-heating system.
Embodiment
As shown in Figure 1, the vacuum oil-filter steam-heating system mainly comprises two heat-exchange systems, and steam carries out heat exchange through heat exchanger I 5 with recirculated water, and recirculated water carries out heat exchange through the oil of heat exchanger II 1 and vacuum oil-filter 25.
Steam gets into heat exchanger I 5 through steam inlet tube 26, break valve 12, filter 13, Pneumatic/electric control valve 14 and Pressure gauge 15 successively, and the condensed water that forms after process heat exchanger I 5 heat exchanges goes out pipe 27 through filter 16, floating ball hydrophobic water valve 17, check-valves 18, ball valve 19 and condensed water successively and leaves.
Recirculated water gets into heat exchanger II 1 through temp probe 6, pressure sensor 7, expansion drum 8, Pressure gauge 9, relief valve 10 and ball valve 11 after leaving heat exchanger I 5 successively, returns heat exchanger I 5 again through ball valve 2, coarse filter 3 and water pump 4 successively through the recirculated water after heat exchanger II 1 heat exchange.
In order to prevent the loss of recirculated water; Also be provided with the recirculated water replenishment system; Specific as follows: the partial condensation water through check-valves 18 gets into water pot 21 through electrical ball valve 20; Part water in the water pot 21 flows into circulating water line through coarse filter 22, water pump 23 and check-valves 24 successively, and gets among the heat exchanger I 5, and water pot 21 is equipped with ball valve (21.1,21.2) and liquid level sensor 21.3.
Large granular impurity in coarse filter (the 3 and 22) filter pipeline, protection water pump (4 and 23) is built-in with the netted filter cylinder of stainless steel, and is easily removable and washable, and it is convenient to change.
Recirculated water by Steam Heating after, temperature rises, and causes circulating water line pressure to rise easily; Expansion of liquids, so expansion drum 8 and relief valve 10 are set, relief valve 10 is when pressure is increased to certain value; Open release with the protection circulating water line, thereby solved the problem of hypertonia and expansion.
In order to arrive effective water temperature, temp probe 6 is set, the temperature of effective detection and Control Circulation water, thereby the temperature of oil in the control vacuum oil-filter 25 are to satisfy demand for heat.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technical staff in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of utility model or surmount the defined scope of these claims, all should belong to the protection range of the utility model.
