Problems solved by technology

Common confined spaces include various storage tanks and containers, sewers and other underground pipes, underground facilities, grain silos, railway tank cars, ship cabins, tunnels, closed transportation channels, etc. Tank car cleaning is a common confined space operation, if Improper operation methods and insufficient protective measures can easily cause personal injury accidents. The main manifestations are: too low oxygen concentration will cause suffocation; too high oxygen concentration may cause unimaginable acceleration or improvement of combustion or other chemical reactions; combustible gas When encountering a fire source and providing a certain amount of energy, it will burn or explode; toxic gases and steam can cause acute or chronic poisoning, or even death; During construction, construction must be strictly organized, and preventive measures such as isolation measures, job ticket management, safety education and training, on-site ventilation, toxic and harmful gas detection, safety monitoring, and preparation of personal protective equipment must be implemented to ensure safe operation; currently domestic tank trucks mainly use steam fumigation However, it has high labor intensity, high environmental pollution, low cleaning efficiency, high energy consumption, and many safety accidents. Foreign countries mostly use high-pressure water cleaning, but the noise is high, the cleaning pressure is high, the power consumption is large, and a large amount of sewage is generated. , causing damage to the tank body; for this reason, we propose an automatic cleaning system for liquid chemical tank trucks and its cleaning process

Abstract

The invention discloses an automatic cleaning system and a cleaning process for a liquid chemical tank truck . The automatic cleaning system comprises an electric appliance operation cabinet, a water inlet pipeline and a tank truck tank body. The water inlet pipeline is fixedly connected with a filter, and the filter is fixedly connected with a booster pump through a pipeline. The booster pump is fixedly connected with a centrifugal pump through a pipeline, and a ball valve is fixedly installed on a connection pipeline between the booster pump and the tank truck tank body. A rotary nozzle is fixedly installed at the tail end of the water inlet pipeline. An automatic lifting device is fixedly connected with a connection pipeline of the rotary nozzle through a steel wire rope, and the rotary nozzle is arranged in an inner cavity of the tank truck tank body. A blowdown pipeline is arranged at the bottom of the tail end of the tank truck tank body, and a stop valve is fixedly installed on the blowdown pipeline. A blowdown pump is fixedly installed at the tail end of the blowdown pipeline, and a PH monitoring unit is arranged at an outlet of the blowdown pump. The booster pump, the automatic lifting device and the blowdown pump are all electrically connected with the electric appliance operation cabinet.

Description

technical field [0001] The invention relates to the technical field of chemical tank car cleaning, in particular to an automatic liquid chemical tank car cleaning system and a cleaning process thereof. Background technique [0002] Due to the frequent occurrence of operation accidents in confined spaces, serious consequences, and bad impact, the safety of operations has attracted great attention from safety supervision departments. Common confined spaces include various storage tanks and containers, sewers and other underground pipes, underground facilities, grain silos, railway tank cars, ship cabins, tunnels, closed transportation channels, etc. Tank car cleaning is a common confined space operation, if Improper operation methods and insufficient protective measures can easily cause personal injury accidents. The main manifestations are: too low oxygen concentration will cause suffocation; too high oxygen concentration may cause unimaginable acceleration or improvement of ...
