Embodiment 1

[0022] see figure 1 , a propylene oxide storage device, the storage device includes a storage tank 1 and a pipeline 7 communicating with the storage tank, the storage device also includes a gas phase condenser 3, a liquid phase condenser 2, a condensate tank and 4 condensate pump 5 , the condensate tank 4 is connected to the gas phase condenser 3 at one end and the condensate pump 5 at one end through a pipeline 7 . Among them, the heat exchange area of ​​the gas phase condenser is at least greater than 100㎡, and the heat exchange area of ​​the liquid phase condenser is at least greater than 100㎡. Propane, the whole system is sealed, without any pollution to the atmosphere.

Embodiment 2

[0023] Example 2 ： As an improvement of the present invention, the storage tank is also provided with a control device, which is used to control the pressure, temperature or liquid level of propylene oxide in the storage tank, and adjust it from time to time according to the situation. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0024] Example 3 ： see figure 2 , as an improvement of the present invention, the control device is configured to include one or more combinations of a pressure transmitter 15, an intelligent radar level gauge 18, and a multi-point thermometer 20, and the pressure transmitter 15 is used to The pressure in the storage tank is adjusted, the liquid level gauge 18 detects the liquid level in the storage tank, and the thermometer 20 detects the temperature in the storage tank from time to time, so as to further ensure that various conditions for storage and transportation are met. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The present invention relates to a propylene oxide storage device and process. The storage device includes storage tanks, storage tank accessories and supporting process pipelines, gas phase pipelines, refrigeration facilities and other public engineering pipeline equipment. It is characterized in that the storage device includes a gas-phase condenser connected to the storage tank and a supporting vacuum pump, a liquid-phase condenser, a condensate tank, a condensate pump and a stirring device in the tank (if necessary, the tank and the tank top freezing plate can be added Compared with the conventional prior art, the advantages of the present invention are as follows, 1), the whole device has simple structure, low cost, and convenient fabrication and transformation; 2), for similar liquid chemical materials such as propylene oxide, the technical solution can completely Effectively achieve the purpose of safe storage under normal pressure; 3), effectively solve the gas phase balance of the "size" breathing of the storage tank during production and storage, especially the closed operation of the whole system, which greatly improves the material loss rate and ensures Very low environmental pollution.

Description

technical field [0001] The invention relates to a storage device, in particular to a propylene oxide storage device and a storage process, belonging to the technical field of chemical industry. Background technique [0002] Propylene oxide is a chemical with flammable, explosive and low boiling point physical and chemical properties. Its explosion limit in air is 2.8~37 volume percent concentration. Burns and emits toxic gases. Its vapor is heavier than air, and can spread to a considerable distance at a lower place, and it will cause back-burning when it encounters an open flame. In particular, its boiling point is 33.9°C. When the storage temperature reaches this value, propylene oxide is highly volatile, causing the vapor pressure in the storage container to be too high. [0003] Due to the above unique physical and chemical properties of propylene oxide, it is extremely important to store temperature, device sealing, tail gas treatment, and loss control during loading ...
