Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical storage, and in particular relates to a leakage-proof hazardous chemical storage tank. Background Art
[0002] Liquefied petroleum gas, usually referred to as LPG, is a by-product obtained by refineries during the catalytic cracking and thermal cracking of crude oil. It is mainly composed of low-boiling point gases such as propane, propylene, butane, butene, and sometimes contains a small amount of pentane, pentene and trace sulfur compound impurities. Liquefied petroleum gas is in a gaseous state at room temperature and pressure, but can be liquefied under pressurized and cooled conditions. It is usually transported and used in pressurized containers. The main uses of liquefied petroleum gas include as a fuel for cooking, vehicle fuel and industrial heating. Due to its high calorific value, no smoke and dust, no carbon residue, and easy operation and use, it is widely used in people's lives. However, liquefied petroleum gas is a flammable and dangerous chemical that is extremely volatile in the air. When it reaches a certain concentration, it may explode when exposed to open flames. Therefore, special attention should be paid to safety during storage and transportation. However, the safety accessories (pressure gauge, liquid level gauge, thermometer, safety valve, sewage pipe, etc.) of the existing liquefied petroleum gas storage tank may fail due to various natural or unnatural reasons. At this time, the storage tank is prone to overfilling or overpressure, which may easily cause the tank body to crack and cause leakage accidents in the long run. Therefore, the utility model proposes a leakage-proof hazardous chemical storage tank to avoid liquefied petroleum gas leakage accidents to the greatest extent. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] Example
[0017] See also Figure 1-2The utility model provides the following technical solutions: a leakage-proof hazardous chemical storage tank, including a tank body and an alarm mechanism, the tank body including an outer tank 1 and an inner tank 2, the inner tank 2 is arranged inside the outer tank 1, bases 3 are welded on both sides of the bottom of the inner tank 2, the base 3 is welded to the bottom wall inside the outer tank 1, a vent 4 is arranged at the center of the top of the outer tank 1, an electric gas valve 5 is installed at the vent 4, the alarm mechanism includes a combustible gas sensor 6 and a controller 7, the combustible gas sensor 6 is respectively installed at both ends of the bottom of the outer tank 1 and the vent 4, the controller 7 is electrically connected to the combustible gas sensor 6 and the electric gas valve 5, in this embodiment, by arranging a layer of outer tank 1 on the outside of the tank body, the space formed between the outer tank 1 and the inner tank 2 is utilized, when the inner tank 2 leaks, the leakage is temporarily stored, and the vent 4 is closed by detecting the corresponding sensor.
[0018] In order to facilitate the installation of corresponding tank accessories, in this embodiment, as a preferred technical solution of the utility model, the pipe body of the inner tank 2 is respectively welded with a safety valve flange 8, a liquid level gauge flange 9, a thermometer flange 10, a gas phase connecting pipe flange 11 and a liquid phase connecting pipe flange 12; the safety valve flange 8, the liquid level gauge flange 9, the thermometer flange 10, the gas phase connecting pipe flange 11 and the liquid phase connecting pipe flange 12 are placed on the outside of the outer tank 1, and the junctions between the outer tank 1 and each flange are sealed and connected by welding.
[0019] In order to increase the stability and strengthen the connection strength between the outer tank 1 and the inner tank 2 , in this embodiment, as a preferred technical solution of the utility model, support columns 13 are evenly welded between the inner tank 2 and the outer tank 1 .
[0020] In order to attract the attention of the staff and remind them to pay attention to the leakage problem, in this embodiment, as a preferred technical solution of the utility model, an audible and visual alarm 14 is fixed on the top of the outer tank 1, and the audible and visual alarm 14 is electrically connected to the controller 7.

[0022] To sum up, with the help of the above-mentioned technical scheme of the utility model, when a leak occurs, the liquefied petroleum gas stored in the inner tank 2 flows from the leak into the space between the outer tank 1 and the inner tank 2. Due to the setting of the vent 4, the outer tank 1 and the inner tank 2 are connected so that they are at normal temperature and pressure. When the liquefied petroleum gas enters between the outer tank 1 and the inner tank 2, it will be converted into a gaseous state. The main components of the liquefied petroleum gas are propane and butane. The density of these substances is much greater than that of air. Therefore, they will sink in the outer tank 1. At this time, it can be detected by the combustible gas sensor 6 that is set. The sensor converts the detection information into an electrical signal and transmits it to the controller 7. Through the controller 7, the electric gas valve 5 is first closed to make the outer tank 1 in a sealed state. At the same time, the sound and light alarm 14 is controlled to give a sound and light alarm prompt.
