Abstract

The utility model relates to a dry type gas cabinet with a high arched central bottom board. The utility model is characterized in that the central bottom board 15 is in the shape of a lifting circular arch, and the bottom edge of the central bottom board 15 and the upper part of an oil groove baffle plate 14 are formed into a water draining groove 19. The utility model has the advantages of little volume of dead space, simple gas replacing operation, little environment pollution, convenient maintenance, corrosion resistance and easy maintenance; a drainer for condensed water of the central bottom board can be arranged on the ground. The lower space of the central bottom board can be used as a storage or other facilities; the second harvest of the gas cabinet is increased.

Description

The dry gas holder of high arch central base sheet

The utility model relates to a kind of coal gas storage device, especially high arch central base sheet dry gas holder.

Everybody thinks that up-to-date best gas cabinet is the COS moulded coal gas holder of Japan at present, this gas cabinet has Germany can swell the oil lubricating system of cylinder blanket and graceful (M, A, N) moulded coal gas holder of (KLONNE) moulded coal gas holder, it combines the advantage of two kinds of form gas cabinets, but because the base plate of gas cabinet is flat, be arranged on the lower end of oil duct dividing plate again, thereby have following shortcoming:

A. the dead space volume of gas cabinet is big, the above dull gas-bearing formation in center region of base plate is thick, stops before the coal gas maintenance displacement when purging residual coal gas, need lay the interim flexible tube that passes the side plate manhole on piston top, coal gas replacement operator complexity, and seriously polluted to surrounding atmosphere during replacement operator.

B. the space below the piston is higher, and to the inspection of piston, maintenance is inconvenient.

C. base plate is overhead nearer, and the hydathode of central base sheet gas condensed water need be arranged in the hole of below ground, thereby the long period of soaking of water in can being cheated, and is perishable, inconvenient maintenance.

D. the easy ponding of flat shape base plate, perishable, it is anticorrosion to need place mat heavy tar (proportion is greater than 1.0).

The purpose of this utility model provides a kind of dry gas holder of high arch central base sheet, solves maintenance, the anticorrosion problem of displacement, emission problem and the base plate of coal gas by the base plate shape that changes gas cabinet.

The purpose of this utility model is achieved in that and is comprising piston, rotation platform, manual rescue device, the ventilation building, inner elevator, the preparation fuel tank, the emergency diffusion pipe, the roof, purge exhaust stack, the oil asending pipe, column, the inner capacities meter, the gas entry pipe, the oil duct dividing plate, central base sheet, oil pump station, side plate, in the gas cabinet of condensed water hydathode, only change the shape and structure of central base sheet, other members remain unchanged, its structure outline is: central base sheet is the dome-shaped of raising, and drainage groove is formed at the top of the base of central base sheet and oil duct dividing plate (14).

Adopt such scheme, the utlity model has following advantage:

1. the dead space volume of gas cabinet reduces, the dull gas-bearing formation in center region more than the base plate is thinner, stop before the coal gas maintenance need not to adopt interim flexible tube when displacement purges residual coal gas, directly adopting extruding type to purge mode just can replace residual gas clean, therefore, the replacement operator of residual gas is greatly simplified.Residual gas also greatly alleviated the pollution level of ambient air when in addition, coal gas was replaced.

2. land at piston, when piston seat adopted telescopic bearing, the following space for maintenance height of piston was expected to maintain between the 1.45-2.2m, suitable maintenance height for check, maintenance provides environmental conditions easily.

3. because central base sheet is raised, and the discharge point position that is condensed in the gas condensed water on the central base sheet is also along with raising, and the gas condensed water hydathode just can be provided with on the ground, like this, has not only reduced expenditure of construction, and corrosion-resistant, safeguard easily.

4. because central base sheet is dome-shaped, being difficult for ponding, thus just can oversimplify the preservative treatment of central base sheet, thus reduced expenditure of construction.

5. after central base sheet was raised, the following space of central base sheet can be opened up as storage and other culture, recreational facilities, to increase the added value of gas cabinet extra earning secondary economic benefit.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a plan view of the present utility model, also is a kind of embodiment of the present utility model.

Fig. 2 is the local rear view that amplifies of Fig. 1.

From above-mentioned accompanying drawing as can be known: the utility model is mainly by piston 1, rotation platform 2, manual rescue device 3, ventilation building 4, inner elevator 5, preparation fuel tank 6, emergency diffusion pipe 7, roof 8, purge exhaust stack 9, oil asending pipe 10, column 11, inner capacities meter 12, gas entry pipe 13, oil duct dividing plate 14, central base sheet 15, oil pump station 16, side plate 17, condensed water hydathode 18 is formed, their annexation and structure characteristic are: piston 1 is installed in side plate 17, it above side plate 17 roof 8, ventilation building 4 is equipped with in 8 tops, roof, and ventilation is equipped with manual rescue device 3 and inner elevator 5 in the building 4; Below roof 8, hanging rotation platform 2, preparation fuel tank 6, emergency diffusion pipe 7 are being housed on side plate 17 outer walls, purge exhaust stack 9, oily asending pipe 10, column 11, inner capacities meter 12, oil pump station 16; In the outside, gas cabinet bottom gas entry pipe 13 is housed, gas entry pipe 13 stretches in the gas cabinet; Central base sheet 15 is equipped with in the bottom in gas cabinet, the dome-shaped of central base sheet 15 for raising, and drainage groove 19 is formed at the top of the base of central base sheet 15 and oil duct dividing plate (14).Can further find out from Fig. 2: condensed water hydathode 18 is positioned on the ground of gas cabinet bottom outside, the bottom position when it stretches into gas cabinet and partly is lower than piston 1 and lands.

From Fig. 1, also can find out: when piston 1 lands (being double dot dash line), the dull gas-bearing formation of dead space more than the central base sheet is very thin, purge gas feeds through gas entry pipe 13, be arranged at side plate 17 outer walls purging exhaust stack 9 on every side respectively by several again and discharge, adopt the purging mode of extruding type just can rapidly residual gas be replaced clean.
