Abstract
The invention relates to an ammonia exhaust device for a freezer. The ammonia exhaust device comprises an ammonia compressor and evaporators which are connected with the ammonia compressor and arranged in the freezer, quick-freezing houses and finished product houses. A main pipe is arranged at the top of the houses, an air inlet of one end is formed in the roof of the ammonia compressor, the other seal end stretches into a water tank, a plurality of exhaust holes are formed in the wall of the main pipe, which stretches into the water tank, and a spray apparatus is arranged above the plurality of exhaust holes. At least one large draught fan is arranged on the main pipe, air inlets of a plurality of branch pipes connected with the main pipe are formed in the roofs of the freezer, the quick-freezing houses and the finished product houses respectively, two layers of iron nets are fixed at the air inlets of the main pipe and the plurality of branch pipes respectively, and a layer of rock wool is arranged between every two layers of iron nets. A stop valve is arranged at the upper end of each air inlet, and a small draught fan is arranged in the pipe between each stop valve and the rock wool. One end of a water draining pipe is connected with the water tank, and the other end is arranged at the position of a water pool. The ammonia exhaust device has the advantages that ammonia can be exhausted effectively during ammonia leakage, and workers are free of ammonia-induced intoxication.
Description
Technical field
The present invention relates to a kind of freezer ammonia excretion device.
Background technology
Refrigeration refers to mechanical means, from a limited space heat removal, makes the temperature at this place be reduced to desired degree, and this process has been transmitted by heat.Refrigeration Technique is that a technique is extremely complicated, has the work of certain risk, and especially the ammonia in system, is a kind of inflammable and explosive, poisonous, and the gas that people is suffocated has potential larger harmfulness to health and safety in production.So require refrigeration serviceman must be familiar with structure, properity, feature, distribution situation, technological process, the operation logic of affiliated freezer equipment, grasp safety operation technology, and possess to look into and suffer from the ability of getting rid of the danger, could be competent at refrigerating operaton and management work like this.In recent years, due to many reasons, domestic that ammonia leakage accident once occurred was a lot of, caused poisoning patient up to a hundred people.
Summary of the invention
In view of the situation of prior art, for fear of ammonia leakage accident, ，Wo unit occurring has increased precautionary measures to existing refrigeration system, and a kind of freezer ammonia excretion device is provided.
For achieving the above object, the technical scheme adopting is in the present invention: a kind of freezer ammonia excretion device, comprises ammonia compressor and the connected freezer that is arranged on, quick freezing repository, evaporimeter in warehouse for finished product, is characterized in that: also comprise iron net, rock wool, little blower fan, large blower fan, pipe valve, water tank, main pipeline, subtube, tapping pipe, spray equipment, described main pipeline is arranged on top, storehouse, its one end air inlet is arranged on the roof of ammonia compressor, another sealing end stretches in water tank, the tube wall that stretches into the main pipeline in water tank is provided with several steam vents, several steam vents top is provided with spray equipment, and at least one large blower fan is installed on main pipeline, and the air inlet of the several subtubes that are connected with main pipeline is separately positioned on freezer, quick freezing repository, on the top, storehouse of warehouse for finished product, on the air inlet of described main pipeline and several subtubes, fix respectively two-layer iron net, between two-layer iron net, be provided with one deck rock wool, in each air inlet upper end, be provided with pipe valve, in pipeline between each pipe valve and rock wool, be provided with little blower fan, one end of described tapping pipe is connected with water tank, and the other end of tapping pipe is arranged on place, pond.
The invention has the beneficial effects as follows: in the situation that there is sudden ammonia leakage, refrigeration work can utilize this device effectively to get rid of cool house internal ammonia, has prevented the poisoning generation of personnel's ammonia.This device can effectively be got rid of ammonia in the very first time, shortens the drawback because of cool house internal structure ammonia excretion overlong time.This device can effectively guarantee that leakage ammonia in storehouse can not be connected in series to other storehouses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that the present invention uses the pipeline of state.
The specific embodiment
As Fig. 1, shown in 2, a kind of freezer ammonia excretion device, comprises ammonia compressor 1 and the connected freezer that is arranged on, quick freezing repository, evaporimeter in warehouse for finished product, also comprises iron net 2, rock wool 3, little blower fan 4, large blower fan 5, pipe valve 6, water tank 7, main pipeline 8, subtube 9, tapping pipe 10, spray equipment 11, main pipeline 8 is fixed on top, storehouse, one end air inlet of main pipeline 8 is arranged on the roof of ammonia compressor 1, the sealing end of main pipeline 8 other ends stretches in water tank 7, on the tube wall of the main pipeline 8 in stretching into water tank 7, be provided with several steam vent 8-1, above several steam vent 8-1, be provided with spray equipment 11, two large blower fans 5 are installed on main pipeline 8, the air inlet of the several subtubes 9 that are connected with main pipeline 8 is arranged on respectively at freezer, quick freezing repository, on the top, storehouse of warehouse for finished product, on the air inlet of main pipeline 8 and several subtube 9 respectively welding or spiral shell fill two-layer iron net 2, between two-layer iron net 2, install one deck rock wool 3 additional, the effect of rock wool 3 is insulation and does not affect ventilation, in each air inlet upper end, be provided with pipe valve 6, pipe valve 6 is in closed condition at ordinary times, guarantee that temperature does not run off, once ammonia leakage, open pipe valve 6 ammonia excretions, in pipeline between each pipe valve 6 and rock wool 3, be provided with little blower fan 4, tapping pipe 10 one end are connected with water tank 7, and tapping pipe 10 other ends are placed in pond or sewer place.Large blower fan is 7.5KW.
Ammonia excretion method: after freezer or quick freezing repository or warehouse for finished product appearance leakage ammonia situation, the refrigerating plant room very first time obtains warning message by ammonia warning device, refrigeration work is worn rapidly safety device and is gone to scene to observe conditions, determine that certain storehouse leaks ammonia, open fan switch or press after automatic ammonia excretion button, pipe valve 6 is opened, ammonia is extracted out by little blower fan 4 and large blower fan 5, ammonia is by subtube 9, main pipeline 8 is sent into water tank 7, the ammonia that 11 pairs of main pipeline 8 tube walls of spray equipment of the interior main pipeline of water tank 78 tops are provided with several steam vent 8-1 discharges sprays, chemical equation is: NH3+H2O=NH3-H2O, ammonia reacts the ammoniacal liquor of generating alkalescent with water, now the water in water tank 7 is ammoniacal liquor, ammoniacal liquor is in tapping pipe 10 flows to pond or sewer.
