[embodiment]
By the following examples, can explain in more detail the present invention, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
The dust suppression of the channel portal described in 1 hinders dirt system by reference to the accompanying drawings, and described system comprises magazine 1, high pressure delivery pipes 2, propulsion system 3 and flusher; In described magazine 1, store can suppress with absorbed air in the liquid blocking-up isolated material of radioactive contamination dust, magazine 1 is communicated with the import of high pressure delivery pipes 2 in being secretly embedded in underground works passway either side conduit wall, the outlet of high pressure delivery pipes 2 is communicated with flusher by propulsion system 3, thereby can utilize the power that propulsion system 3 provide that the blocking-up isolated material in magazine 1 is delivered to flusher by high pressure delivery pipes 2, and finally utilize flusher by 2～3m
3the flow of/min sprays to the channel portal of underground works uniformly by blocking-up isolated material with the form of atomization, the blocking-up isolated material of ejection can form and meet absorption and the spray pattern that requires of pressing pressure is suppressed and adsorbs the radioactive dust flying away, and then reaches the object that effectively prevents radioactive dust admission passage inside;
The blocking-up isolated material of applying in described system is comprised of following components in mass portion: acrylate copolymer 100, zinc acetate 6, polynite 25, dimethyl silicon oil 13, dioctyl phthalate 25 and analysis pure acetone 80, its preparation method is: in acrylate copolymer, add zinc acetate, after 60 ℃ of ultrasonic mixing 0.5～1h, add successively again polynite, dimethyl silicon oil, dioctyl phthalate and analysis pure acetone, then after the ultrasonic mixing 0.5～1h of normal temperature, be prepared into described material; Wherein, described acrylate copolymer is undertaken making after the reaction of free radical random copolymerization by the mass ratio of 50:45:5 by methyl methacrylate, butyl acrylate and acrylic acid, or, can carry out instead of propylene acid polymer with organic-silicon-modified resin;
For making the atomization blocking-up isolated material of ejection effectively adsorb radioactive dust and to suppress, the spraying pipeline 4 that the multiple tracks that described flusher is arranged along both sides, underground works passway by correspondence is made by Steel Tube Special, and interval is arranged on a plurality of atomizers 5 compositions of body respective channel mouth middle part one side of every one spraying pipeline 4 uniformly; For ease of controlling sprinkling amount, every one spraying pipeline 4 is provided with by-pass valve control 6; Needs according to carrying blocking-up isolated material, can adopt one or more centrifugal pump as propulsion system 3, thereby to guarantee to meet conveying requirement; In addition, described propulsion system 3 can be provided with automatic control system, and this control system is comprised of centralized control treatment circuit, frequency converter, pressure measurement sensor, shock wave induction installation, radiation detector, electrically operated valve and shielding protection facility, thereby reach by can automatically responding to the control system of relevant information the object that automatic control propulsion system 3 start or stop; Because described automatic control system need be implemented location and installation according to the concrete structure of different underground civil defense engineering channel portals, and the technician who is familiar with automatic control system all knows that in this system, all parts is wanted corresponding connection position, therefore, the present invention connects and no longer describes in detail the concrete installation of all parts in described automatic control system.
While implementing the dust suppression resistance dirt system of channel portal of the present invention, only need by the structural correspondence of underground works channel portal in the described system of first protective door outside application, then just can by described system spray can correspondingly suppress with absorbed air in the blocking-up isolated material of radioactive contamination dust reach the object of guarantee underground works internal staff and device security; When application, described propulsion system using be placed in channel portal shock wave induction installation as first tripper, using radiation detector as second tripper, when twice alarm is triggered, described system starts automatic spraying blocking-up isolated material, and stops sprinkling until radiation detector detects after external radiation value is down to below setting value again;
In addition, described system can also be used in conjunction with sealed door, and described system senses radioactive contamination dust in air, and closes sealed door when automatic spraying blocking-up isolated material, thereby has more efficientlyly guaranteed the safety in underground works; As required, can also described system be set in underground works channel portal inner side, even reaching sealed door with this occurs damaged, or there is a small amount of radioactive contamination dust admission passage oral area, also can utilize area that atomization blocking-up isolated material that described system sprays covers to carry out the area of space of effective protection channel mouth inner side, thereby the radioactive contamination dust of admission passage oral area is suppressed and is adsorbed in this, guaranteed that radioactive dust can never enter into underground works inside, and then effectively ensured the safety of related personnel and equipment;
Compare with existing channel portal isolation technology, described system does not affect the discrepancy of personnel and vehicle when application, and it is not only high to the adaptability of environment, the atomizing material modest viscosity of spraying, trickling property is controlled, can use-10～50 ℃ wide temperature ranges, its inhibition is better simultaneously, to being not more than the inhibiting rate of the radioactive dust carrying in 10m/s moving air, can reach more than 95%.
Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
