Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, in the case where it is judged that the description for the related well-known function or structure may unnecessarily obscure the gist of the present invention, a detailed description thereof will be omitted.
As shown in fig. 1, the emergency disposal apparatus of the present invention includes first and second storage chambers 2 and 3 and a separation assembly.
A draft tube 1 is connected to the first storage chamber 2 to receive the discharge liquid comprising the first phase and the second phase. In the following description, the hydrogen peroxide solution in the extraction tower of the hydrogen peroxide solution production apparatus is described as a discharge liquid, and in this case, the hydrogen peroxide solution includes an organic phase and an aqueous phase, wherein the first phase is an organic phase, the second phase is an aqueous phase, and the first phase and the second phase can be separated into layers, so that the first phase is located above the second phase, and the second phase is located below the first phase. This is shown for illustrative purposes only and the present invention is not limited thereto and the emergency treatment device of the present invention is preferably but not limited to use with effluent that rapidly generates large quantities of gas, which may include more phases or multiple phases that may not be stratified with respect to each other.
The upper portion of first locker room 2 opens the setting, and when hydrogen peroxide solution discharged to first locker room 2 through drainage tube 1 rapidly, a large amount of gases that hydrogen peroxide solution decomposes the production fast can diffuse to atmospheric environment fast to can avoid the emergence of explosion accident.
As shown in fig. 1, the first storage room 2 may be in the form of a pond having only side walls and a bottom wall, and the present invention is not limited to a specific form.
In addition, the second storage room 3 is provided as a closed space, and the first phase in the first storage room 2 is discharged into the second storage room 3 through the separation assembly, thereby preventing the first phase from being deteriorated by oxidation. The first phase in the discharged liquid is separately discharged into the second storage chamber through the separation assembly, so that the first phase can be recycled or treated in a centralized manner.
The second storage room 3 may be provided separately from the first storage room 2, but for the sake of compactness, in the present invention, as a preferred embodiment, as shown in fig. 1, the first storage room 2 and the second storage room 3 are formed as one body. Specifically, one partition wall 13 is provided in the middle of one accident pool to form two storage spaces, and a top wall is provided at the top of one storage space to form the first storage room 2 and the second storage room 3, and the first storage room 2 and the second storage room 3 are provided on one accident pool 12 to make the entire apparatus compact. However, the present invention is not limited thereto, and the first storage room and the second storage room may be separately provided according to specific requirements, for example, when the second storage room storing the first phase needs to be moved to another place, the separate second storage room may be provided on the mobile trailer for movement.
In addition, the capacity of the emergency treatment device of the invention can be designed according to the working conditions, and preferably, the sum of the volumes of the first storage chamber 2 and the second storage chamber 3 can be designed into the capacity of the device which needs to drain the accident substances. For example, in the case of the hydrogen peroxide production apparatus, since the gas explosion event may occur in the extraction tower and the purification tower, the sum of the volumes of the first storage chamber 2 and the second storage chamber 3 may be designed as the sum of the hydrogen peroxide stock volumes in the extraction tower and the purification tower. But the invention is not limited thereto.
The separating assembly is a component for separately discharging the first phase in the first storage chamber into the second storage chamber, and the specific structure may include a plurality of structures, for example, a separating door capable of moving up and down may be disposed on the partition wall 13, in an initial state, the separating door is in a closed state, after the discharged liquid in the first storage chamber 2 is stabilized, the first phase and the second phase are separated into layers, and then the separating door is controlled to move downwards slowly, so that the first phase located above in the first storage chamber 2 flows into the second storage chamber.
But as a more preferred embodiment, as shown in fig. 1, the separating assembly comprises an oil suction pipe 9 and a suction pump 4 provided on the oil suction pipe 9, one end of the oil suction pipe 9 being located in the first phase inside the first storage chamber 2 and the other end of the oil suction pipe 9 being located in the second storage chamber 3. The suction speed of the first phase can be controlled by the suction frequency of the suction pump 4.
Wherein, in order to make the oil suction pipe 9 always located in the first phase, it is preferable that the pipe density of the end of the oil suction pipe 9 located in the first phase inside the first storage chamber 2 is greater than the first phase density and less than the second phase density, thereby avoiding the second phase from being sucked into the second storage chamber.
On this basis, the emergency treatment device may further include a level gauge 6, and the level gauge 6 is disposed in the discharge liquid. Based on the stratification position fed back by the level gauge 6, it can be controlled whether the separation assembly continues to perform the suction. When the stratification disappears, or the liquid thickness of the first phase approaches 0, fed back from the level gauge 6, the separation assembly can be closed at this time to prevent the second phase from being sucked into the second storage chamber 3.
The above is a preferred embodiment of the first storage room 2. The following continues with a description of a preferred embodiment of the second storage room 3.
The organic phase sucked into the second storage chamber 3 may further contain undecomposed hydrogen peroxide, which may be decomposed in the second storage chamber 3 to generate oxygen, however, in order to avoid the organic phase reacting with the oxygen, the emergency treatment device provided by the present invention may further include a vent valve 5, a first valve port of the vent valve 5 is connected to a first pipe 8 for introducing nitrogen, and a second valve port of the vent valve 5 is connected to the second storage chamber 3 through a second pipe 10. Thereby, nitrogen gas is flushed into the second storage chamber 3.
In addition, the breather valve 5 is a three-way valve for discharging oxygen in the second storage chamber 3, and a third pipe 11 is connected to a third port of the breather valve 5. More preferably, the ventilation valve 5 is a self-supporting regulating valve, and the ventilation valve 5 can automatically adjust the opening degree according to the oxygen content in the second storage chamber 3, thereby ensuring the pressure balance inside the second storage chamber 3. When the oxygen content is higher than a certain value (for example, more than 10%), nitrogen can be introduced to replace the oxygen, and when the internal pressure of the second storage chamber is lower, nitrogen can also be introduced, and the processes can be automatically completed. It should be noted that the oxygen content in the second storage chamber 2 can be sampled manually or monitored online, and the invention is not limited in particular.
In addition, as a preferred embodiment, a metal net 7 may be disposed on the bottom surface of the second storage chamber 3 to accelerate the decomposition of the hydrogen peroxide solution that enters the second storage chamber 3 in a small amount. As the material of the metal mesh 7, stainless steel may be selected, and the shape of the metal mesh may be irregular, but the present invention is not limited thereto.
The hydrogen peroxide production device comprises an extraction tower and a purification tower, and further comprises the emergency treatment device, and the emergency treatment device is respectively communicated with the extraction tower and the purification tower through a drainage tube 1. When an accident occurs in the extraction tower and/or the purification tower of the hydrogen peroxide production device, the hydrogen peroxide can be quickly introduced into the emergency treatment device provided by the invention through the drainage tube, and as the hydrogen peroxide solution is in an open environment, a large amount of oxygen generated when the hydrogen peroxide is quickly decomposed can be quickly diffused, so that the phenomena of explosion and the like can be avoided, and the organic phase in the hydrogen peroxide solution is independently discharged into the second storage chamber through the separation component, so that the organic phase can be recycled or intensively treated.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, numerous simple modifications can be made to the technical solution of the invention, including combinations of the individual specific technical features in any suitable way. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
