Description
Technical field
The utility model relates to a kind of circulation means, relates in particular to a kind of cooling water internal circulation system.
Background technique
Come temporarily entering winter ice breast, a large amount of ice breasts appear in generating subsidiary factory cooling water channel, when the unit cooling water moves; mix a large amount of ice breasts and entered the unit cooler; cause icing that breast enters cooler so that cooler stops up, a unit watt temperature rises, and causes unit failure to shut down.Use now coldly go that unit is upper and lower, water leads cooler and composed in parallel by four minutes copper pipe, and lead the cooling water survey at upper and lower, water viewing window is housed, in the draining survey current indicator is housed, be beneficial to when unit operation, can observe at any time cooling water runnability, and the unit cooling water is to supply water by the unit penstock.Because Southern Xinjiang winter is cold, one is lower than zero degree to winter temperature, and the channel amount of ice increases, and it is newborn that especially a large amount of ice appear in channel, when the unit cooling water moves, mixed a large amount of ice breasts and entered the unit cooler.When unit operation, be easy to cause the ice breast to enter cooler so that cooler stops up, a unit watt temperature rises, and such as untimely dredging cooler, will cause the generation of burning accident, causes unit failure to shut down.
Summary of the invention
The purpose of this utility model is to propose a kind ofly to avoid occurring in the winter time cooler and freeze to stop up, and prolongs the cooler cooling water internal circulation system in working life.
The purpose of this utility model is achieved in that the cooling water internal circulation system is by the cooling water house steward, be connected in parallel on the cooling water branched pipe on the cooling water house steward, water pipe, the collector pipe that is communicated with each cooling unit, sump forms, each cooling unit comprises the cooling line of three tunnel parallel connections, cooler is led in installing respectively on three road cooling lines, under lead cooler, water is led cooler, each cooling line one end that cools off unit is communicated with the cooling water branched pipe, the cooling water branched pipe is unit cooling water house steward No. one, or No. two unit cooling water house stewards, or No. three unit cooling water house stewards, it is characterized in that: the cooling line the other end is communicated with draft tube and collector pipe respectively, the intake pipe that catchments of collector pipe end stretches in the sump, in cooling water branched pipe side water pipe is set, each water pipe is in parallel, on water pipe, install from outside to inside water supply valve, water filter, unit cooling water house steward wherein, the water pipe of No. two unit cooling water house steward sides links to each other with No. two recycle pumps with a recycle pump, and a recycle pump and No. two recycle pumps are arranged in the sump.
Owing to implementing technique scheme, unit cooling water system normal operation, cooler have been avoided causing unit failure to shut down number of times because cooling water system breaks down without blocking phenomenon.The cooler copper tubes transducer wall ' s abrasion is reduced, prolong cooler working life.Reduce the sump pollution discharge pump number of starts, prolong pollution discharge pump working life.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is cooling water internal circulation system structural representation.
Legend: 1, unit cooling water house steward, 2, water leads cooler, 3, lead cooler down, 4, lead cooler on, 5, No. two unit cooling water house stewards, 6, No. three unit cooling water house stewards, 7, collector pipe, 8, the cooling water house steward, 9, No. two recycle pumps, 10, the intake pipe that catchments, 11, draft tube, 12, sump, 13, recycle pump, 14, water filter, 15, water supply valve, 16, water pipe.
Embodiment: the utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, the cooling water internal circulation system is by cooling water house steward 8, is connected in parallel on cooling water branched pipe, water pipe 16 on the cooling water house steward 8, and the collector pipe 7, the sump 12 that are communicated with each cooling unit form.Each cooling unit comprises the cooling line of three tunnel parallel connections, and installing is led cooler 4, led cooler 3 down respectively on three road cooling lines, water is led cooler 2.Each cooling line one end that cools off unit is communicated with the cooling water branched pipe, and the cooling water branched pipe is unit cooling water house steward 1 No. one, or No. two unit cooling water house stewards 5, or No. three unit cooling water house stewards 6.The cooling line the other end is communicated with draft tube 11 and collector pipe 7 respectively, and the intake pipe 10 that catchments of collector pipe 7 ends stretches in the sump 12.At draft tube 11 pressure regulator valve is set.In cooling water branched pipe side water pipe 16 is set, water supply valve 15, water filter 14 are installed in each water pipe 16 parallel connection from outside to inside on water pipe 16.Wherein the water pipe 16 of a unit cooling water house steward 1, No. two unit cooling water house steward 5 sides links to each other with No. two recycle pumps 9 with a recycle pump 13, and a recycle pump 13 and No. two recycle pumps 9 are arranged in the sump 12.
The factory building sump during 12 winter water temperature generally remain on 3-5 ℃, and without ice breast and other foreign material.By being installed, two recycle pumps and auxiliary piping be connected with cooling water house steward 8, come temporarily entering winter ice breast, with the unit penstock, namely the water supply valve 15 on the water pipe 16 is closed, open a recycle pump 13 or No. two recycle pumps 9 and supply water to the unit cooler, two recycle pumps are for subsequent use each other.Observe camera by sump 12 water-level control apparatus and sump 12 water levels and control, adjust sump 12 water levels: after measured water level surpasses predetermined water level, the float inner contact is closed, start the 24V relay, the 24V relay is connected the contactor coil on the major loop, the charged adhesive armature of coil, the major loop energising starts water pump, reduces sump 12 water levels, after being down to predetermined water level.The float inner contact restores, the automatic disconnection of contactor power supply, and recycle pump is out of service.When sump 12 water levels were observed when low by observing camera, get rid of the water yields and adjust unit sump 12 water levels by reducing draft tube 11.When the unit cooling water pressure is too high or too low, also can adjust the unit cooling water pressure by adjusting draft tube 11 water displacement.
Above technical characteristics has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characteristics, satisfies the needs of different situations.
