Liquefied gas loading and unloading position spraying device

Abstract

The invention discloses a liquefied gas loading and unloading position spraying device comprising an upper firefighting pipeline and a lower firefighting pipeline. A plurality of vertical firefightingpipelines are arranged between the upper firefighting pipeline and the lower firefighting pipeline. Each vertical firefighting pipeline is provided with a plurality of spraying nozzles. One end of the upper firefighting pipeline is provided with a spraying stop valve. One end of the last vertical firefighting pipeline is provided with a spraying discharge valve. A combustible gas alarm instrumentis arranged behind each vertical firefighting pipeline. The liquefied gas loading and unloading position spraying device has the characteristics of being reasonable in structure design and convenientto use, emergencies of overtemperature and a leak appearing in the loading and unloading process of a lift truck can be found and disposed in time in emergency circumstances, operation is simple, risk possibly caused by manual work is reduced, loading and unloading safety is improved greatly, and stable and safe loading and unloading are ensured.

Description

technical field [0001] The invention relates to a spraying device, in particular to a spraying device for a liquefied gas loading and unloading parking space. Background technique [0002] Liquefied gas raw materials and products are transported by tank trucks. Generally, production enterprises have multiple loading and unloading spaces, and most of them are loaded and unloaded by pumps as power. Although this method can complete the loading and unloading of liquefied gas raw materials and products, it has the following disadvantages: 1. If the tank car is overheated, overpressured or overloaded during the loading and unloading process, causing the safety valve to jump or leak on site, there is no reliable If the equipment and facilities cool down the tanker or dilute the liquefied gas leaked on site, there will be great safety hazards; 2. Once an emergency occurs, it will evolve into a major accident. Contents of the invention [0003] The purpose of the present inventio...
