Technical field
The utility model relates to nuclear and uses active carbon adsorber, is specifically related to a kind of absorber and inhales/send injection apparatus with active carbon.
Background technology
Nuclear is vitals in the nuclear power station with active carbon adsorber, is mainly used in the gaseous iodine mixture in the removal air in the nuclear facilities air cleaning system.Its design relation is to security, reliability and the economy of nuclear power station.
After nuclear power station puts into operation, the adsorber system exhaust outlet is carried out dose monitoring, when dosage reaches certain numerical value, need the active carbon in the absorber is changed effectively.Because the absorber refulling cycle is longer, active carbon quantity of sorbent in the course of the work is more.Therefore, exploitation one cover safety, reliably, the active carbon loading and unloading material system is very necessary easily.
Summary of the invention
It is a kind of when absorber reloads that the purpose of this utility model is to provide, quick and safe is finished the replacing process of active carbon reliably, reduces radgas and the dust of dust in cargo handling process injection apparatus is inhaled/sent to the absorber of operating personnel's harm with active carbon.
Realize the technical scheme of the utility model purpose: injection apparatus is inhaled/sent to a kind of absorber with active carbon, and this injection apparatus comprises anemostat, mixing chamber, diffusion end flanges plate, nozzle end flanged plate and nozzle; Wherein mixing chamber inside is cavity, and the top offers the active carbon import; The mixing chamber both sides are fixedly connected with diffusion end flanges plate and nozzle end flanged plate respectively, and anemostat is fixed on the diffusion end flanges plate, and are connected with the mixing chamber internal cavity, and nozzle is fixed on the nozzle end flanged plate, and is connected with the mixing chamber internal cavity.
Injection apparatus is inhaled/sent to aforesaid a kind of absorber with active carbon, and its described anemostat port of export area is greater than the entrance point area, and entrance point is weldingly connected with diffusion end flanges plate.
Injection apparatus is inhaled/sent to aforesaid a kind of absorber with active carbon, and its described jet expansion end area is less than the entrance point area, and the port of export extends into the mixing chamber internal cavity, and the middle part of nozzle is welded on the nozzle end flanged plate.
Injection apparatus is inhaled/sent to aforesaid a kind of absorber with active carbon, and its described nozzle and anemostat axis coincide.
Effect of the present utility model is: injection apparatus is inhaled/sent to absorber described in the utility model with active carbon, one is positioned at feed bin bottom and is used for discharging in absorber, another is positioned at the conveying that the charging bung is used for active carbon, important component part for dress active carbon discharge system, adopt the closed-loop path, can effectively reduce the leakage of radgas and dust.Its injector compact overall structure, engaged position is little, guarantees the convenience and the safety of installation process.In dress (unloading) process, adopt the air-flow that produces by blower fan when injector, to produce negative pressure, finish effective suction of active carbon and send.Absorber is inhaled/is sent injection apparatus with active carbon and adopts air-transport system to replace artificial loading and unloading, and whole process is safer effectively.

The specific embodiment
Below in conjunction with the drawings and specific embodiments injection apparatus is inhaled/sent to absorber described in the utility model with active carbon is further described.
As depicted in figs. 1 and 2, injection apparatus mainly is made up of anemostat 11, mixing chamber 12, diffusion end flanges plate 13, nozzle end flanged plate 14, nozzle 15 5 parts.Wherein, mixing chamber 12 inside are cavity, and the top offers the active carbon import, and diffusion end flanges plate 13 is weldingly connected with mixing chamber 12 1 side ends, and nozzle end flanged plate 14 is weldingly connected with mixing chamber 12 end side.Anemostat 11 inside are truncated cone shape, and port of export sectional area is greater than the entrance point sectional area, and its entrance point is weldingly fixed on the diffusion end flanges plate 13.Nozzle 15 is connected to form successively by four sections pipelines that sectional area successively decreases gradually, and port of export area is less than the entrance point area, and nozzle 15 middle parts are welded on the nozzle end flanged plate 14, and the port of export of nozzle 15 extends in the middle of mixing chamber 12 internal cavities.For keeping the efficient of injection apparatus as far as possible, need the concentricity that keeps certain between nozzle 15 and the anemostat 11.
As shown in Figure 3 and Figure 4, in absorber, adopt the described injection apparatus of two playscript with stage directions utility models altogether, one is positioned at feed bin bottom and is used for discharging, and another is positioned at the conveying that the charging bung is used for active carbon.All being provided with respective line at injection apparatus nozzle 15 entrance points and anemostat 11 ports of export links to each other with blower fan and absorber.
During discharging, the closed loop (Fig. 3) by feed bin bottom (being connected by snap joint between PVC flexible pipe and each parts in the loop), by the air-flow of blower fan generation behind nozzle 15, the formation high-speed jet.This jet produces the gas in the mixing chamber in the process of advancing and entrainments and rolling action, in mixing chamber, produce negative pressure shape and become vacuum, active carbon in the hopper is inhaled in the mixing chamber, and under the carrying of gas jet, enter anemostat 11, after further mixing, two of diffusion pipeline section gas-solids enter follow-up transfer pipeline.
When filling with substance, after by the charging carriage tool active carbon bucket being tumbled, the injection apparatus by charging bung below is transported to active carbon in the absorber the same discharging of its operation principle.(Fig. 4)
By the test, the efficient of this injection apparatus is higher, the conveying capacity of active carbon greater than 600 kilograms per hour, effectively reduced reloading the time of absorber.
