Abstract
The utility model provides a liquid ammonia transportation system which comprises a liquid ammonia storage tank, a piston compressor, a mass flow meter, and a liquid ammonia block valve. A liquid ammonia outlet is arranged in the liquid ammonia storage tank and is communicated with the piston compressor through a pipeline. The mass flow meter and the liquid ammonia block valve are arranged on the pipeline between the liquid ammonia outlet and the piston compressor. A pressurizing opening is additionally formed in the liquid ammonia storage tank and is connected with an automatic pressurizing device. A gas ammonia outlet is arranged in the liquid ammonia storage tank. The liquid ammonia transportation system has the advantages of being safe and fast in transportation, loading and unloading of liquid ammonia, autometering can be achieved at the same time, and efficiency is high.
Description
Technical field
The utility model belongs to the conveying equipment for fluid substances field, especially relates to a kind of liquefied ammonia transporting system.
Background technique
Liquefied ammonia is called again anhydrous ammonia, is a kind of colourless liquid.Ammonia is widely used as a kind of important industrial chemicals, be transportation and store convenient, usually with the ammonia of gaseous state by pressurization or the cooling liquid ammonia that obtains.Liquefied ammonia is widely used industrial, and has corrosivity, and easily volatilization, so its chemical accident incidence rate is quite high.
Unload ammonia from liquid ammonia storage tank and generally adopt sliding vane pump to carry, the degree of vacuum that produces due to sliding vane pump is little, and the interior ammonia of storage tank unloads unclean, and the clean ammonia of remaining on board rushes down outward, causes environmental pollution, has simultaneously great potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of liquefied ammonia transporting system, makes the conveying of liquefied ammonia, loading and unloading safer, faster, simultaneously can realize autoweighing, and efficient is higher.
The technical solution of the utility model is: the liquefied ammonia transporting system, comprise liquid ammonia storage tank, piston compressor, mass flowmenter and liquefied ammonia cut-off valve, liquid ammonia storage tank is provided with the liquefied ammonia exhaust port, the liquefied ammonia exhaust port is communicated with piston compressor by pipeline, and the pipeline between liquefied ammonia exhaust port and piston compressor is provided with mass flowmenter and liquefied ammonia cut-off valve.
Further, described liquid ammonia storage tank is provided with boost port, and boost port connects self-supercharging device, and liquid ammonia storage tank is provided with the gas ammonia exhaust port.
Advantage and the good effect that the utlity model has are: replace former sliding vane pump with piston compressor, ammonia in liquid ammonia storage tank can be shifted fully, avoided ammonia to leak fully, use safer; Mass flowmenter can be in the process that liquefied ammonia is carried autoweighing, use conveniently, improved efficiency; Liquid ammonia storage tank is installed self-supercharging device, can realize that the vaporization of liquefied ammonia is carried, and the mode of movement variation is used more convenient.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the utility model is a kind of liquefied ammonia transporting system, comprise liquid ammonia storage tank 1, piston compressor 2, mass flowmenter 3 and liquefied ammonia cut-off valve 4, liquid ammonia storage tank 1 is provided with liquefied ammonia exhaust port 5, liquefied ammonia exhaust port 5 is communicated with piston compressor 2 by pipeline, and the pipeline that liquefied ammonia exhaust port 5 and piston compressor are 2 is provided with mass flowmenter 3 and liquefied ammonia cut-off valve 4.
Further, described liquid ammonia storage tank 1 is provided with boost port, and boost port connects self-supercharging device 6, and liquid ammonia storage tank 1 is provided with gas ammonia exhaust port 7.
Replace former sliding vane pump with piston compressor 2, the interior ammonia of liquid ammonia storage tank 1 can be shifted fully, avoided ammonia to leak fully, use safer; Mass flowmenter 3 can be in the process that liquefied ammonia is carried autoweighing, use conveniently, improved efficiency; Liquid ammonia storage tank 1 is installed self-supercharging device 6, coordinates gasification installation to use, and can realize that the vaporization of liquefied ammonia is carried, and the mode of movement variation is used more convenient.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
