Abstract
The utility model relates to an anti-freezing equipment overflow water seal structure which comprises an overflow pipe. The overflow pipe is arranged on the inner wall of a container and is of a U-shaped structure in shape. A water adding opening, an overflow opening and a sewage discharging opening are formed in the outer wall of the container. The water adding opening, the overflow opening and the sewage discharging opening are communicated with the corresponding positions of the overflow pipe on the inner wall of the container. The water adding opening and the sewage discharging opening are provided with valves. The water adding opening is higher than the overflow opening. The sewage discharging opening is communicated with the lowest part of the overflow pipe. The structure can achieve freezing resisting and blocking resisting of overflow water sealing at the same time, an external connecting pipe is simple, and construction mounting and production management are convenient.
Description
Technical field
The utility model relates to a kind of equipment overflow water seal structure, particularly a kind of anti-freeze type equipment overflow water seal structure.
Background technology
The container major parts such as tower in commercial production, groove, tank are provided with the medium overflow of overflow pipe when exceeding certain liquid level, and use equipment is no more than effective capacity and structure allows load, the safety of protection equipment and structure.For being full of process gas on liquid level and having the equipment of airtight requirement, often on overflow pipe, increase water-gland, the height of water seal is determined by the operating pressure of equipment, according to the size that has of container inner pressure, equipment is divided into negative pressure equipment and malleation equipment, and two types of equipment overflow pipe ways are basically identical, make one section of " U " type curved by overflow pipe, and be full of liquid, utilize " U " type pipe pressure equilibrium principle that the gas in equipment is not communicated with ambient atmosphere.
Result in blockage because the particulate matter in overflow medium deposits in order to prevent that " U " type is curved, conventionally by curved " U " type external container that is placed on, so that clear up and add water, but for the area that has in the winter time ice period, outdoor low temperature will make the curved interior liquid of " U " type freeze and lose overflow effect, conventionally take the hot measure of insulation companion, otherwise overflow pipe afunction, which is mainly adapted to southern area.At northern area, conventionally the curved water seal of " U " type is placed on to internal tank, utilize working medium temperature in container to efficiently solve the problem of freezing higher than the feature of ambient temperature, stop up and water seal adds water but but exist to clear up.
Utility model content
The purpose of this utility model is to provide a kind of anti-freeze type equipment overflow water seal structure, and this structure can solve antifreeze, the blockage problem of overflow water seal simultaneously, and outer tube is simple, and constructability is installed and production control.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of anti-freeze type equipment overflow water seal structure, comprise overflow pipe, it is characterized in that, on the container inner wall that described overflow pipe is arranged on, it is shaped as U-shaped, filler, outgate, sewage draining exit is set and is communicated with the relevant position of the overflow pipe on container inner wall at the outer wall of container, and described filler, sewage draining exit are equipped with valve, the position of described filler is higher than outgate, and sewage draining exit is communicated with the bottommost of overflow pipe.
When water seal adds water, close sewage draining exit valve, open filler valve filler is connected with outer water tube, make to be full of liquid in overflow water seal.
When water seal is used, close filler and sewage draining exit valve.
In the time having deposition of solid to clear up in overflow pipe, directly open sewage draining exit valve, put the liquid in dry overflow pipe, after being cleaned out, the sediment in overflow pipe in water seal, adds water again.
The utility model has the advantage of: 1, this device by overflow pipe equipment the inwall at body, can directly be immersed in the liquid in container, not only there is fluid-tight and overflow effect, also there is antifreeze effect, not there is not " siphon " phenomenon, can not freeze because outside air temperature is too low, not need in device external, attemperator to be set in addition; 2, filler, sewage draining exit are all set directly at that body is outside to be communicated with overflow pipe, conveniently add water, blowdown and clear up overflow pipe.3, integral structure is simple, is easy to construction and installation and production control.
Accompanying drawing explanation
Fig. 1 is the utility model anti-freeze type equipment overflow water seal structure schematic diagram;
In figure: 1, shell of tank, 2, overflow pipe, 3, filler, 4, outgate, 5, sewage draining exit.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of anti-freeze type equipment overflow water seal structure, comprise the overflow pipe 2 that is attached to shell of tank 1 inwall, overflow pipe 2 is " U " type structure, be provided with filler 3, outgate 4, sewage draining exit 5 and be communicated with the opposite position of the overflow pipe 2 of container inner wall respectively at the outer wall of shell of tank 1, for convenience of switching manipulation, filler 3, sewage draining exit 5 are equipped with valve, filler 1 can external water pipe, outgate 4 conduit connectables are to scene melt pit, the position of described filler 3 is higher than outgate 4, and sewage draining exit 4 is communicated with the bottommost of overflow pipe 2.
When water seal adds water, close the valve of sewage draining exit 5, open the valve that filler 3 connects outer water tube, make to be full of liquid in overflow water seal.
When water seal is used, close the valve of filler 3 and sewage draining exit 5.
In the time having deposition of solid to clear up in overflow pipe 2, directly open the valve of sewage draining exit 5, put the liquid in dry overflow pipe, the sediment in overflow pipe is cleaned out.
Embodiment: desulfurizer is that example illustrates this utility model below.
Desulfurizer is the void tower of positive pressure operation, pressure p=5kPag, cleansing fluid density p=1000kg/m3, the diameter D=4m of tower body.
Overflow pipe height liquid seal H=p/(ρ g)=0.51m.
When desulfurizer is not worked (p=0kPag), close sewage draining exit valve, add water in overflow pipe by filler, until outgate there are flowing out, illustrate in overflow pipe fluid-tight and be full of water.When desulfurizer work (p=5kPag), tower internal pressure rises, and forms the fluid-tight post that the discrepancy in elevation is 0.51m and can effectively prevent that in tower, gas leaks outside by overflow pipe in overflow pipe.In the time that liquid level in tower rises to overflow liquid level due to accident causation, in tower, liquid passes through outgate overflow, thereby makes liquid level in tower no longer continue to rise, and the height liquid seal in fluid-tight is constant.Can regularly open the blowdown of sewage draining exit valve, prevent that overflow pipe from stopping up because of deposition of solid.
Claims (1)
