Abstract
The utility model relates to an ammonia discharge device for a refrigeration house. The ammonia discharge device comprises an ammonia compressor and evaporators, wherein the evaporators are connected with the ammonia compressor and arranged in the refrigeration house, a quick-freezing house and a finished-product house respectively. A main pipeline is arranged on the top of the refrigeration house, wherein a gas inlet at one end of the main pipeline is arranged on the roof of the ammonia compressor, and the other closed end of the main pipeline extends into a water tank. The wall of the portion, extending into the water tank, of the main pipeline is provided with a plurality of gas vent holes. A spray device is arranged above the multiple gas vent holes. At least one large fan is installed on the main pipeline. Gas inlets of a plurality of branch pipelines connected with the main pipeline are arranged on the top of the refrigeration house, the top of the quick-freezing house and the top of the finished-product house respectively. Two iron nets are fixed to the gas inlet of the main pipeline, and two iron nets are fixed to the gas inlets of the multiple branch pipelines. A layer of rock wool is arranged between every two corresponding iron nets. A stop valve is arranged at the upper end of each gas inlet. A small fan is arranged in the portion, between each stop valve and the corresponding rock wool, of the corresponding pipeline. One end of a water draining pipe is connected with the water tank, and the other end of the water draining pipe is arranged at a pool. The ammonia discharge device for the refrigeration house has the advantages that ammonia gas can be effectively discharged under the condition of ammonia gas leakage, so that people are prevented from being poisoned by ammonia gas.
Description
Technical field
The utility model 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, occur, my unit 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 the utility model: 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 beneficial effects of the utility model are: 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 utility model;
Fig. 2 is the structural representation that the utility model is used the pipeline of state.
The specific embodiment
As Fig. 1, shown in 2, 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.
