Description

Compressor with ammonia leakage detection function

The technical field is as follows:

the utility model relates to a loading and unloading field of ammonia, concretely relates to compressor with ammonia leakage detection function.

Background art:

the supporting ammonia station that is provided with of deNOx systems, store liquid ammonia in the ammonia station and supply the deNOx systems to use, liquid ammonia is transported by special tank wagon usually, and rethread compressor unloads liquid ammonia to the storage tank at ammonia station from special tank wagon in.

The compressor is the main equipment of unloading the ammonia, and long-term use can make the compressor appear wearing and tearing between packing bearing seal, oil blanket and the piston rod, and then the leakproofness variation, and the in-process of unloading the ammonia causes the ammonia to pass packing bearing seal and oil blanket and gets into the crankcase, and the following problem can appear in the ammonia leaks to the crankcase: 1. the ammonia gas can react with partial parts such as copper parts, so that certain damage is caused to the parts in the crankcase; 2. the ammonia volume is less difficult to discover when just leaking, but when the ammonia gathering makes the leakage volume increase in the crankcase, can lead to crankcase internal pressure too big, and a large amount of ammonia are erupted from crankcase oil filler point or gap suddenly, because the ammonia has the hypertoxic, is inhaled internal and will seriously threaten personal safety.

The utility model has the following contents:

an object of the utility model is to provide a compressor with quick, the convenient function that detects is leaked to ammonia.

The utility model discloses by following technical scheme implement:

a compressor with an ammonia leakage detection function comprises a compressor main body and a transparent hose, wherein the compressor main body consists of a cylinder main body, a filling chamber and a crankcase which are sequentially communicated; a crankshaft is rotatably arranged in the crankcase; the crankshaft is provided with at least two piston rods penetrating through a top plate of the crankcase; the top end of the piston rod passes through the packing chamber and is arranged in the cylinder main body; a packing shaft seal assembly and a middle gasket are sleeved on the piston rod in the packing chamber; an air-stop sealing ring is sleeved on the piston rod between the middle gasket and the crankcase; an oil seal assembly is sleeved on the piston rod in the crankcase; two adjacent middle gaskets are communicated through a pipeline; the transparent hose penetrates through the side wall of the filling material chamber in a sealing mode and is communicated with any one of the middle gaskets, and the other end of the transparent hose is connected with a recovery device.

Preferably, the recovery device is a wastewater pond.

The utility model has the advantages that: 1. due to the characteristic that ammonia absorbs heat and frosts, the transparent hose can be cooled when the ammonia circulates in the transparent hose, the leakage condition of the shaft seal of the compressor can be found in time, the treatment in time is convenient, and the ammonia cannot enter a crankcase to damage parts; 2. when the ammonia leakage amount is large, the ammonia can be safely discharged to the recovery device through the transparent hose to be treated, the phenomenon of leakage of the ammonia outside the air can not occur, and potential safety hazards are avoided.

Description of the drawings:

in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: the device comprises a compressor body 1, a wastewater tank 2, a piston rod 3, a crankshaft 4, a cylinder body 5, a packing chamber 6, a crankcase 7, a packing shaft seal assembly 8, an intermediate gasket 9, an oil seal assembly 10, a pipeline 11, a transparent hose 12, an air-stop sealing ring 13 and a recovery device 14.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, a compressor with ammonia leakage detection function comprises a compressor body 1 and a transparent hose 12, wherein the compressor body 1 is composed of a cylinder body 5, a filling chamber 6 and a crankcase 7 which are communicated in sequence; a crankshaft 4 is rotatably arranged in the crankcase 7; the crankshaft 4 is provided with at least two piston rods 3 penetrating through a top plate of a crankcase 7; the top end of the piston rod 3 is arranged in the cylinder main body 5 through the packing chamber 6; a packing shaft seal assembly 8 and a middle gasket 9 are sleeved on the piston rod 3 in the packing chamber 6; an air-stop sealing ring 13 is sleeved on the piston rod 3 between the middle gasket 9 and the crankcase 7; an oil seal assembly 10 is sleeved on the piston rod 3 in the crankcase 7; two adjacent middle gaskets 9 are communicated through a pipeline 11; the transparent hose 12 penetrates through the side wall of the packing chamber 6 in a sealing manner and is communicated with any one of the intermediate gaskets 9, ammonia gas leaks to the intermediate gasket 9 through the packing shaft seal assembly 8, and the ammonia gas cannot leak downwards due to the sealing of the gas stop sealing ring 13, so the ammonia gas can only be discharged through the pipeline 11 and the transparent hose 12, and due to the characteristic that the ammonia gas absorbs heat and frosts, the transparent hose 12 can be cooled when the ammonia gas circulates in the transparent hose 12, the leakage condition of the compressor shaft seal can be found in time, the treatment in time is facilitated, and the ammonia gas cannot enter the crankcase 7 to damage parts; the other end of the transparent hose 12 is connected with the recovery device 14, when the ammonia leakage amount is large, the ammonia can be safely discharged into the recovery device 14 for processing, the recovery device 14 is the wastewater disposal basin 2, the phenomenon of ammonia leakage to the air can not occur, and the potential safety hazard can be avoided.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
