Abstract
The utility model relates to a novel high pressure feed water heater hydroecium baffle convenient to overhaul, its technical scheme lies in: it welds on the jar body with whole semicircular in shape, its middle part sets up the inspection hole that is closed by the blind plate lid, the blind plate is the stairstepping with the sealed face of baffle, threaded connection face that the up end that lies in the baffle was relatively drawn together to the sealed bread of stairstepping and the lower terminal surface that lies in the baffle relatively adiabatic sealed, sealed glue is paintd to adiabatic sealed face when the installation, the threaded connection face evenly sets up the screw hole, connect baffle and blind plate through fixing bolt, the outside at the blind plate is equipped with the handle, compared with the prior art, the outstanding advantage that has the easy access, and can effectively reduce the feedwater adds the baffle to the height abrasion.
Description
Technical field
The utility model relates to electricity power technical field, specifically relates to a kind of novel high-pressure heater hydroecium dividing plate of easy access.
Background technology
It is the important component part of Steam Turbine Regenerative System that height adds, its Main Function utilizes the steam doing merit extracted out from steam turbine, heat the deaerated water sent from feed pump, improve feed temperature, save energy consumption, leak if height adds inner hydroecium dividing plate, part will be made to feed water and to can not get heating, reduce the heat transfer effect that height adds, existing most heater hydroecium dividing plate forms semilune by 4 pieces of platelets, overlap between dividing plate, be screwed on dividing plate frame, dividing plate and dividing plate frame faying face high pressure asbestos pad seal, asbestos pad is washed away by water after water soaking, cause and sew, under constantly the washing away of high-pressure feed water, sealing surface between dividing plate and dividing plate frame is washed rough and uneven in surface, sew serious, feed temperature is caused to reduce, certain customers are in order to eliminate interior leakage, integrally welded for several pieces of dividing plate electric welding, although eliminate interior leakage, but must cut open during maintenance, larger difficulty is brought to service work.
Utility model content
The purpose of this utility model is exactly the deficiency existed for prior art, disclose a kind of novel high-pressure heater hydroecium dividing plate of easy access, by arranging all-in-one-piece hydroecium dividing plate, reaching to eliminate in channel for HP heater dividing plate and leaking, improve feed temperature, be convenient to the object of keeping in repair.
Technical scheme: a kind of novel high-pressure heater hydroecium dividing plate of easy access, it is characterized in that: it is welded on tank body with overall semicircular in shape, the inspection opening covered by blind plate is set in the middle part of it, the sealing surface of blind plate and dividing plate is stairstepping, stairstepping sealing surface comprises the thread joint face of the upper surface being relatively positioned at dividing plate and the relative adiabatic sealing surface being positioned at the lower surface of dividing plate, adiabatic sealing surface smears fluid sealant when mounted, thread joint face evenly arranges screwed hole, by set bolt connecting partition and blind plate, at the arranged outside handle of blind plate.
Described inspection opening and the blind plate be mated are round rectangle.
Beneficial effect: this utility model compared with prior art, has the outstanding advantages of easy access, and the erosive wear that effectively can reduce that feedwater to add dividing plate to height, ensured the safety of high adding system, economy and stable operation.
Accompanying drawing explanation
Accompanying drawing 1 is the plan structure schematic diagram of the present embodiment; Accompanying drawing 2 is threaded connection place schematic diagrames of the present embodiment.
Detailed description of the invention
With reference to accompanying drawing 1 and accompanying drawing 2, a kind of novel high-pressure heater hydroecium dividing plate 2 of easy access, it is welded on tank body 1 with overall semicircular in shape, the inspection opening 9 covered by blind plate 7 is set in the middle part of it, blind plate 7 is stairstepping with the sealing surface of dividing plate 2, stairstepping sealing surface comprises the thread joint face 3 of the upper surface being relatively positioned at dividing plate 2 and the relative adiabatic sealing surface 4 being positioned at the lower surface of dividing plate 2, adiabatic sealing surface 4 smears fluid sealant 10 when mounted, thread joint face 3 evenly arranges screwed hole 5, by set bolt 8 connecting partition 2 and blind plate 7, at the arranged outside handle 6 of blind plate 7, described inspection opening 9 and the blind plate 7 be mated are round rectangle.
This patent is on probation on Datang northern Shandong Power Generation Corporation Ltd. high-pressure heater, feed temperature more than 15 degree is improved after two Transformation of Units, according to " Datang group company fired power generating unit energy consumption index analysis and guidance suggestion ", feed temperature often changes 10 degree, affect coal consumption 0.75g/kwh, then annual saving generating mark coal: 4 × 10
10kwh × 80% × 0.75g/kwh=2400(ton), save cost of electricity-generating: 2400 × 500 yuan/ton=120(ten thousand yuan).
Claims (2)
1. the novel high-pressure heater hydroecium dividing plate of an easy access, it is characterized in that: it is welded on tank body with overall semicircular in shape, the inspection opening covered by blind plate is set in the middle part of it, the sealing surface of blind plate and dividing plate is stairstepping, stairstepping sealing surface comprises the thread joint face of the upper surface being relatively positioned at dividing plate and the relative adiabatic sealing surface being positioned at the lower surface of dividing plate, adiabatic sealing surface smears fluid sealant when mounted, thread joint face evenly arranges screwed hole, by set bolt connecting partition and blind plate, at the arranged outside handle of blind plate.
2. the novel high-pressure heater hydroecium dividing plate of easy access according to claim 1, is characterized in that: described inspection opening and the blind plate be mated are round rectangle.
