Description

Technical Field

[0001] The utility model relates to the technical field of liquid chlorine transportation, in particular to an automatic control system for gas phase chlorine pressure for safe transportation of liquid chlorine tank trucks. Background Art

[0002] Liquid chlorine is liquid chlorine, which vaporizes into gas under normal pressure. Inhalation can cause severe poisoning to the human body. It is highly irritating and corrosive. It will burn and explode when mixed with other flammable gases under sunlight. Therefore, special attention should be paid to the safety of liquid chlorine during transportation. During the transportation of liquid chlorine tank trucks, once the pressure of the liquid chlorine tank truck reaches the tripping pressure of the safety valve, the safety valve will trip and cause serious social accidents such as chlorine leakage. Liquid chlorine is a highly toxic liquefied gas. The gas phase pressure of the liquid chlorine tank truck depends on the temperature of the liquid chlorine in the tank truck. When the temperature rises, the gas phase pressure of the liquid chlorine tank truck will also increase. In the extremely high temperature season in summer, the tank truck may reach dangerous temperatures and pressures when exposed to the sun for a long time, thus causing safety accidents. In the prior art, a pressure gauge is installed on the roof of a liquid chlorine tank truck. If one wants to check the pressure, one can only climb to the roof to check it on the spot. It is inconvenient to check the pressure, especially when the liquid chlorine tank truck is in motion. The state of pressure change cannot be checked at any time. Early warning and early disposal are not possible when overpressure occurs. It is difficult to accurately know the chlorine gas pressure in the liquid chlorine tank truck during transportation and use of the liquid chlorine tank truck. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic control system for the safe transportation of liquid chlorine tank trucks in order to overcome the shortcomings of the prior art. The pressure display of the liquid chlorine tank truck is sent to relevant personnel in real time through 5G communication technology, which can remotely monitor the pressure in real time, promptly detect chlorine overpressure and issue an alarm.

[0004] According to the utility model, an automatic control system for safe transportation of liquid chlorine tank trucks is proposed, including a liquid chlorine tank truck with a storage tank, a pressure gauge, a 5G communication network, and a monitoring and alarm console. The pressure gauge is installed in the gas phase space on the top of the liquid chlorine tank truck. A sheath is provided on the top of the liquid chlorine tank truck. The pressure gauge is connected to the monitoring and alarm console signal through the 5G communication network, and the monitoring and alarm console is connected to the liquid chlorine tank truck driving terminal signal.

[0005] Preferably, the pressure gauge is a pressure gauge with 5G remote transmission function, including a pressure detection gauge body, in which a pressure measurement sensor, a pressure measurement display and a pressure signal transmitter are assembled, the signal input end probe of the pressure measurement sensor is in contact with the chlorine gas layer of the liquid chlorine tank truck, the signal output end of the pressure measurement sensor is connected to the signal input end of the pressure measurement display, and the signal output end of the pressure measurement display is connected to the pressure data signal transmitter.

[0006] Preferably, an isolation valve is provided between the pressure gauge and the storage tank.

[0007] Preferably, the pressure detection gauge body is made of stainless steel.

[0008] Preferably, the top of the storage tank is connected to a liquid chlorine filling pipeline, and a filling valve is provided on the filling pipeline.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] During the transportation of liquid chlorine tank trucks, the gaseous chlorine pressure of the liquid chlorine tank trucks is connected to the signal of the liquid chlorine tank truck driving terminal through 5G communication technology. When the chlorine pressure of the liquid chlorine tank truck reaches a dangerous value, an alarm is issued in advance and the alarm information is remotely sent to the driver, escort and major hazardous source transportation dispatcher of the liquid chlorine tank truck, so as to avoid safety accidents caused by the tripping of the safety valve due to excessive pressure in the liquid chlorine storage tank, resulting in large-scale leakage of chlorine. Through this utility model, the real-time status of the pressure change of the liquid chlorine tank truck can be timely and effectively grasped. The pressure display of the liquid chlorine tank truck is sent to relevant personnel in real time through 5G communication technology to monitor the pressure development trend in real time. Before the chlorine pressure reaches a dangerous value, an alarm is issued to notify the driver and escort of the liquid chlorine tank truck and check the nearest chlorine-alkali production enterprise with disposal capacity or the enterprise with chlorine pressure relief acceptance capacity on the mobile phone map for pressure relief treatment, thereby ensuring the safety of the liquid chlorine tank truck.
