Safety configuration structure of liquid chlorine storage equipment

Abstract

The invention provides a safety configuration structure of liquid chlorine storage equipment. The top of a liquid chlorine storage tank (1) is provided with a safety pipeline and a safety valve (4), the pipeline behind the safety valve (4) is connected to a leaching tower (7), and the safety valve (4) is provided with an automatic alarm device (5) and can automatically start an alkaline pump (6); the column line of a shed type building (2) is provided with a circle of closed low wall (8); the shed type building (2) is internally provided with two layers of chlorine gas concentration detectors (15), and each detector (15) is provided with an automatic alarm device which can inform personnel of evacuating, to overhaul and to process leaked chlorine gas in time; the lower side of an eaves of the shed type building (2) is provided with a circle of annular pipeline (9); and a circle of closed dike (11) is added around the shed type building (2). The structure can prevent the liquid chlorine storage tank from being damaged or leaking probably caused by pressure lifting, can also prevent the liquid chlorine storage tank, the pipelines or the valve from leaking to avoid environmental pollution and threat to surrounding personnel and can provide important safeguard for safe production and environmental protection.

Description

technical field [0001] The invention relates to the configuration structure of liquid chlorine storage, in particular to the safe configuration structure of liquid chlorine storage. Background technique [0002] In the production of many industrial enterprises, a large amount of chlorine gas is used. In order to facilitate transportation and storage, it is generally used in liquid form. In the previous designs of liquid chlorine storage tanks, liquid chlorine storage tanks were usually installed in a building with only columns and a roof, and the liquid chlorine storage tanks were directly connected to the production unit with only one valve and one pipeline. Such a design has certain security risks. On the one hand, there are no walls on all sides of the building, which is good for ventilation. It can only make the chlorine gas leaked from the tanks, pipes, valves, etc. in the building indoors as little as possible to gather in the building indoors, but the environment aro...

Problems solved by technology

Such a design has certain security risks.

On the one hand, there are no walls on all sides of the building, which is good for ventilation. It can only make the chlorine gas leaked from the tanks, pipes, valves, etc. in the building indoors as little as possible to gather in the building indoors, but the environment around the building has not been protected. people working or staying around the building still pose a health and safety threat

On the other hand, buildings with roofs can only reduce the effect and influence of direct sunlight, but cannot prevent the pressure increase caused by other factors (such as sudden increase in ambient temperature, excessive canning, sudden stop of gas consumption by production equipment, etc.) Danger

[0003] In the prior art, the Chinese patent application number 97224005.5 discloses an intermediate buffer tank for chlorine gas filtration, which makes the gasification of liquid chlorine relatively safe and alleviates the impact of high-pressure chlorine gas on the relationship to a certain extent, but this buffer tank is difficult to solve the above-mentioned liquid chlorine. The hidden danger problem of storage; the application number is that the Chinese patent of 200520074182.3 has announced the chlorine leakage processing device with liquid chlorine processing capacity, and the Chinese patent application number is 200510041340.X has announced the chlorine leakage processing device with liquid chlorine processing capacity, they A treatment device for chlorine gas leakage is provided, but this device only works for gas leakage, without basic alarm or reminder information, and has little effect in small-scale gas leakage, and it is also difficult to solve the safety of the above-mentioned liquid chlorine storage Hidden problems
