Abstract
The utility model relates to an explosion venting device for a distilling column. The explosion venting device is characterized by comprising an explosion venting pipe, a blowdown receiving tank and a safety valve; one end of the explosion venting pipe is connected on a distilling kettle; an explosion venting port at the other end of the explosion venting pipe is inserted in the blowdown receiving tank; and the safety valve is arranged in a pipeline (close to a communicated part of the distilling kettle) of the blowdown pipe. The explosion venting device for the distilling column has the advantages that once the pressure in the distilling column is excessively high during use, the safety valve can be automatically switched on, parts of vented mediums are fed into the blowdown receiving tank by the explosion venting port, so that the purposes of reducing the pressure in the column and avoiding the damage such as exploding can be realized, and the safety in the explosion venting process can be ensured.
Description
Technical field
The utility model belongs to a kind of explosion venting device, is specifically related to a kind of explosion venting device of destilling tower.
Background technology
Destilling tower can be realized the separation of different volatility liquid mixtures, belongs to the unit operations common equipment that the chemical industry mass transfer separates.When separated mixture contains flammable liquid or fuel gas, along with the rising of temperature and pressure in the tower, after combustible is broken through its explosion limit, will inevitably cause huge harm.In addition, along with destilling tower is operated operation for a long time, its tower body can be worn, the burn into cavitation erosion, causes tower wall attenuate, and the body of the tower bearing capacity weakens, and has potential safety hazard.
Summary of the invention
ThisThe purpose of utility model is to overcome the potential safety hazard that destilling tower exists in running, and a kind of safe and reliable destilling tower explosion venting device is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the safe explosion venting device of a kind of destilling tower, it is characterized in that, comprise detonating fusee, blowdown reception tank and safety valve, described detonating fusee one end is connected on the distillation still, and the other end venting of dust explosion mouth of detonating fusee inserts in the blowdown reception tank, and described blowdown pipe is provided with a safety valve near in the distillation still connectivity part pipeline.
The utility model has the advantage of: during use, when the destilling tower internal pressure was too high, safety valve can be opened automatically, through the venting of dust explosion mouth, the part medium that will release passes in the blowdown reception tank, reaches to reduce the tower internal pressure, the purpose of harm such as avoid exploding, this venting of dust explosion process safety.
Description of drawings
Fig. 1 is the structure chart of destilling tower explosion venting device in the utility model.
The specific embodiment
As shown in Figure 1, comprise distillation tower body 1, distillation still 2, detonating fusee 3, safety valve 4, venting of dust explosion mouth 5 and blowdown reception tank 6, described detonating fusee 3 one ends are connected on the distillation still 2, the other end venting of dust explosion mouth 5 of detonating fusee inserts in the blowdown reception tank 6, and described blowdown pipe 3 is provided with a safety valve 4 near in the distillation still 2 connectivity part pipelines.
During use, when destilling tower 1 internal pressure was too high, safety valve 4 can be opened automatically, and through venting of dust explosion mouth 5, the part medium that will release passes in the blowdown reception tank, reached and reduced the tower internal pressure, and avoid exploding and wait the purpose that endangers, simultaneously, this venting of dust explosion process safety.
