Abstract
The invention discloses a device for recycling ammonia gas in a refrigerating unit with liquid ammonia serving as a refrigerating fluid. The recovery device comprises a cylindrical ammonia gas absorption tank, wherein the diameter of the upper part of the ammonia gas absorption tank is smaller than that of the lower part of the ammonia gas absorption tank; an ammonia emptying inlet and an ammonium water outlet are formed in the middle of the ammonia gas absorption tank; the ammonia emptying inlet is connected with an ammonia gas outlet of the refrigerating unit through a pipeline; a spraying water inlet is formed above the ammonium water outlet; the ammonium water outlet is connected to an underground ammonia water storage tank through a pipeline. In an actual application process, if the pressure of the unit exceeds the standard or other accidents occur, ammonia gas emptied after a unit safety valve is on is recycled into the ammonia gas absorption tank which is mainly filled with water, the ammonia gas and the water are mixed to form ammonium water, and the ammonium water is recycled by virtue of the ammonia gas absorption tank, so that the ammonia gas can be recycled in the accident state, the phenomena that the environment is influenced and the surrounding environment is polluted due to emptying of ammonia gas into the atmosphere are prevented, an operator is prevented from security threat, and the aims of safety, environmental protection, circular economy are achieved.
Description
Technical field
The present invention relates to liquefied ammonia and make the retracting device of ammonia in the freezing unit of freezing liquid.
Background technology
Chilled water required in synthesis gas preparing ethylene glycol device is mostly from freezing unit, the freezing liquid of freezing unit is liquefied ammonia, it is the freezing liquid that current freezing unit is generally used that liquefied ammonia is done freezing liquid, because liquefied ammonia economy, but in actual application, if run into system overhaul or unit pressure exceeds standard or occurs under the state of other accidents, unit safety valve can take-off, gas ammonia emptying after take-off, thus caused environmental pollution and field personnel's personal safety has been formed to threat.
Summary of the invention
The present invention does freezing liquid freezing unit for solving existing liquefied ammonia in application process, runs into system overhaul or unit pressure exceeds standard or occurs the problem that other contingencies cause ammonia to be revealed, and the retracting device of ammonia in the freezing unit that a kind of liquefied ammonia does freezing liquid is provided.
Liquefied ammonia of the present invention is made the retracting device of ammonia in the freezing unit of freezing liquid, comprise that upper diameter is less than the cylindricality ammonia tourie of lower diameter, medium position at described ammonia tourie is provided with ammonia emptying import and ammoniacal liquor outlet, and described ammonia emptying import connects the ammonia outlet of freezing unit by pipeline; Above described ammoniacal liquor outlet, be provided with shower water import; Described ammoniacal liquor outlet is connected to the underground storage tank of ammoniacal liquor by pipeline.
Described ammonia emptying import department is connected with the Inserting Tube that gos deep into ammonia tourie bottom, and the termination of described Inserting Tube is provided with several Inserting Tube jet pipes, and described Inserting Tube jet pipe is provided with several spray orifices.
Described shower water import department is connected with the shower that gos deep into ammonia tourie inside, and described shower is provided with several spray apertures.
The bottom surface of described ammonia tourie is inclined-plane, on the ammonia tourie near lower position place, described inclined-plane, is provided with discharging hole.
Ammonia tourie principle of the present invention, is by freezing unit discharge ammonia, by pipeline, enters into ammonia tourie, by the Inserting Tube in ammonia tourie, by the jet pipe of Inserting Tube end opening, ammonia is discharged in water again, utilizes the high-dissolvability of ammonia in water, allow the fast reaction of gas ammonia and water, generate ammoniacal liquor, utilize the outlet of ammonia tourie, ammoniacal liquor by automatic overflow to the underground storage tank of ammoniacal liquor, thereby the ammoniacal liquor of absorption can be delivered to ammonia water tank to sell, reduce industrial cost; Ammonia tourie of the present invention is suitable for reading also designs a set of spray water system, utilize the even spray of shower water, allow gas ammonia in water, there is no the ammonia dissolving, in the process of spray, dissolve gas ammonia completely, and spray water system is returned the good supplementing water of ammonia tourie.Low cost of manufacture of the present invention, high efficiency, makes simple, using environment-friendly; The ammonia that fully emptying in the state of accident of absorption refrigerating unit is replaced to the liquefied ammonia of atmosphere with when the system overhaul, effectively preventing that gas ammonia emptying is to air, impact is operating environment around, when affecting operating personnel's safety, also ammonia has been carried out to recycling, lowered industrial cost.
In actual application, if unit pressure exceeds standard or occurs under the state of other accidents, after the take-off of unit safety valve, the gas ammonia of emptying will be recovered to ammonia tourie, in ammonia tourie, be mainly water, gas ammonia and water mix, form ammoniacal liquor, utilize ammonia tourie, reclaim ammoniacal liquor, thereby realized in the state of accident, reclaimed gas ammonia, prevented that gas ammonia emptying from affecting environment and polluting surrounding environment to atmosphere, avoid the security threat to operating personnel, played the object of safety, environmental protection and recycling economy.
