Abstract
The utility model discloses a safety interlocking system used in the preparation process of chlorine dioxide. The safety interlocking system comprises a reactor and is characterized in that the reactor is connected with a redundancy negative pressure monitoring point; the redundancy negative pressure monitoring point is connected with a data communication system (DCS); and the DCS is connected with a raw material feeding device, an emergency water tank, an air feeding device, a tail gas washing device and a manual device. According to the technical scheme, when the redundancy negative pressure monitoring point detects that negative pressure is greater than a set value, the system can automatically adjust the vacuum degree of the device; after the adjustment is failed, an alarm is given immediately, raw materials are fed, a valve of the emergency water tank is opened, and cold water is injected into the reactor for quenching to reduce the temperature of the reactor so as to stop chemical reaction; after the system is in a stopped state, the negative pressure of the system can automatically return to the safe state, and after an operator manually relieves the safe state, the negative pressure of the system can return to the working state; and the system is also provided with an automatic emergency pressure release valve, so that the safety of the reactor and the operator is guaranteed.
Description
Technical field
The utility model relates to the technical field for preparing dioxide peroxide, is specifically related to a kind of dioxide peroxide and prepares the safety interlocking system in the journey.
Background technology
In the preparation process of dioxide peroxide, need carry out detection at any time, when negative pressure surpasses set(ting)value to negative pressure; System if regulate failure, also need report to the police the vacuum tightness of setting device immediately and stop raw material and add; And take other corresponding measure to reduce the temperature of reactor drum, stop chemical reaction.If operator wait other unsafe factor because of sleep, will bring very big danger to system.
In order to eliminate the Hazard Factor of dioxide peroxide in the preparation process, prior art does not still have good terms of settlement.
The utility model content
The utility model has overcome the deficiency of prior art, provides a kind of dioxide peroxide of dioxide peroxide safe preparation process of protecting to prepare the safety interlocking system in the journey.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of dioxide peroxide prepares the process safe locking system; Comprise reactor drum; Said reactor drum is connected with redundant negative pressure monitoring point; Said redundant negative pressure monitoring point is connected with the DCS system, and said DCS system is connected with hand gear with raw material adding apparatus, emergent tank, air adding apparatus, washing tail gas device again.
In order better to realize the utility model, technical scheme further is:
As preferably: said DCS system also is connected with automatic decompression device.
Compared with prior art, the beneficial effect of the utility model is:
In the technical scheme of the utility model; When redundant negative pressure monitoring point detects negative pressure above set(ting)value; System is with automatic-adjusting device vacuum tightness, and reporting to the police immediately after the adjusting failure and stopping raw material adding, and opens emergent tank valve; In reactor drum, inject the cold water quenching to reduce temperature of reactor, stop chemical reaction; Feed air diluents after filtering simultaneously rapidly, the gas after the dilution is evacuated to the washing tower exhaust emissions rapidly; After system was in stopped status, system's negative pressure was got back to safe condition automatically, just can get back to working order after must manually being removed by operator.As extreme safety control, system has also increased the automatic emergency pressure release valve and has guaranteed reactor drum and personal security.
Description of drawings
Fig. 1 is the schematic flow sheet of the utility model;
Fig. 2 is the system schematic of the utility model.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
As depicted in figs. 1 and 2; A kind of dioxide peroxide prepares the process safe locking system; Comprise reactor drum; Said reactor drum is connected with redundant negative pressure monitoring point, and said redundant negative pressure monitoring point is connected with the DCS system, and said DCS system is connected with raw material adding apparatus, emergent tank, air adding apparatus, washing tail gas device, hand gear and automatic decompression device again.
Native system is a braking locking system, and purpose is exactly the safe operation of assurance system, when system's negative pressure is undesired; And the operator does not have unusual circumstance, does not carry out correct adjusting, and this automatic interlock will be regulated automatically so; If the adjusting failure will be reported to the police and stopped the adding of raw material and some measures of back automatically automatically; And open emergent tank valve, and in reactor drum, inject the cold water quenching to reduce temperature of reactor, stop chemical reaction; Feed air diluents after filtering simultaneously rapidly, the gas after the dilution is evacuated to the washing tower exhaust emissions rapidly.
Claims (2)
1. a dioxide peroxide prepares the process safe locking system; Comprise reactor drum; It is characterized in that: said reactor drum is connected with redundant negative pressure monitoring point; Said redundant negative pressure monitoring point is connected with the DCS system, and said DCS system is connected with hand gear with raw material adding apparatus, emergent tank, air adding apparatus, washing tail gas device again.
