Description
Technical field
The utility model relates to a kind of dimension pressure sealing device of reactor, is more specifically a kind of dimension pressure sealing device that maintains reactor lower pressure, belongs to technical field of chemical.
Background technology
In some chemical process, be reacted to and only need to have kept small pressure latter stage, as produced in the reaction of Ludox at elemental silicon, arrived last stage reaction and only needed the reaction pressure below 0.05MPa, and the amounts of hydrogen that reaction relaxes, produces is also fewer.Because its reaction pressure is small, in existing actual production, often adopt and close the micro-open type reaction of minor valve, the result causing like this: the one, do not maintain microresponse pressure, the pressure transient of reaction system, affects reaction effect; The 2nd, open type reaction easily makes reaction mass contact with air, has larger potential safety hazard, as elemental silicon, produces in the reaction of Ludox, and micro-unlimited meeting causes air to enter reactor, has the potential safety hazard of blasting with the hydrogen that reacts generation.
Utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined is to provide a kind of dimension pressure sealing device that maintains the reactor of reactor microresponse pressure and pressure stability, air-isolation, to improve reaction effect, eliminates safe hidden trouble.
For achieving the above object, the present invention is by the following technical solutions: a kind of dimension pressure sealing device of reactor, it comprises water tank and tube connector, described tube connector is provided with valve, on reactor, be provided with connector, the bottom of described water tank is provided with outlet pass, and two ends of described tube connector are communicated with the connector on reactor, the outlet pass of water tank respectively; In course of reaction, in described water tank, be equipped with water, the difference in height Δ h of described Water in Water Tanks face and reactor connector is 0.5-5 rice.
Described valve is control valve, in described reactor, is provided with pressure sensor, and described pressure sensor is connected with control valve signal.
On described tube connector, there is the bending of U-shaped.
On described water tank, be also provided with water replanishing device.
Adopt such scheme, the dimension pressure sealing device of reactor of the present utility model, because the connector on reactor is communicated with by tube connector with water tank, and in course of reaction, the difference in height Δ h of Water in Water Tanks face and reactor connector is 0.5-5 rice.The microresponse pressure that can keep like this reactor 0.005-0.05MPa.In the application of the dimension pressure sealing device of reactor of the present utility model, the difference in height of Water in Water Tanks face and reactor connector can be determined according to concrete response situation.As produced in the reaction of Ludox at elemental silicon, the difference in height Δ h of Water in Water Tanks face and reactor connector specifically can be set to 4 meters.
In a word, the dimension pressure sealing device of reactor of the present utility model is applicable to maintaining reactor microresponse pressure and pressure stability, air-isolation, to improve reaction effect, guarantees safety in production.
In addition, on water tank, be also provided with water replanishing device, can guarantee the stable of Water in Water Tanks face height.Valve adopts control valve, and in reactor, be provided with pressure sensor, sensor is connected with control valve signal, like this, in the time of can being less than at the pressure of reactor setting pressure (namely the difference in height of Water in Water Tanks face and reactor connector is the water column pressure of Δ h), closed control valve, prevent that water pot from entering reactor, when the pressure of reactor is greater than setting pressure, opening controlling valve, maintains setting pressure by the difference in height that maintains Water in Water Tanks face and reactor connector.
