Pollution control equipment

直接觀察操作開放型放射性物質(zhì)，通常都在有適當(dāng)通風(fēng)的通風(fēng)柜或手套箱內(nèi)進(jìn)行。

Direct observation of open radioactive materials is usually carried out in a properly ventilated fume hood or glove box.

通風(fēng)柜

Fume hood

通風(fēng)柜是放射性同位素實(shí)驗(yàn)室常用的污染控制設(shè)備.可根據(jù)操作放射性核素的種類、活度、操作性質(zhì)等進(jìn)行設(shè)計(jì)。其主體結(jié)構(gòu)宜采用不銹鋼制作通常為尺寸通常為1.2-1.8mx0.8-0.85mx 1.5m(長(zhǎng) x深x 高 )，將其放置在試驗(yàn)臺(tái)而上。

Fume hood is a common pollution control equipment in radioisotope laboratory. It can be designed according to the type, activity and operation property of radionuclides. The main structure should be made of stainless steel, usually with the size of 1.2-1.8mx0.8-0.85mx 1.5m (length x depth x height), and placed on the test bench.

其操作面宜采用平衡拉窗，（可分兩扇)式.拉窗上安裝硅酸鹽玻璃;過濾器設(shè)置在通風(fēng)柜的上部，采用離心式排風(fēng)機(jī)，將其安裝在頂部，以便使廢氣管道內(nèi)保持負(fù)壓;通風(fēng)柜操作口的截面風(fēng)速應(yīng)不小于Im.s-1，并利用自動(dòng)的旁路來(lái)防止柜門關(guān)閉時(shí)，風(fēng)速的驟然增加。

The operation surface should adopt balanced sliding window, which can be divided into two types; The filter is arranged on the upper part of the fume hood, and the centrifugal exhaust fan is adopted, which is installed on the top, so as to maintain negative pressure in the waste gas pipeline; The cross-section wind speed of the fume hood operation port shall not be less than im. S-1, and the automatic bypass shall be used to prevent the sudden increase of wind speed when the cabinet door is closed.

通風(fēng)柜的內(nèi)表面應(yīng)采用易去污材料.如不誘鋼板或PVC板。拒的底部可采用耐酸瓷磚或不銹鋼板;柜內(nèi)設(shè)置煤氣、冷熱水、污水排出口;用暗裝日光燈作為通風(fēng)柜內(nèi)部照明.其照明標(biāo)準(zhǔn)為150一300 Lx(勒克斯)，電源插座設(shè)置在通風(fēng)柜外部。

The inner surface of the fume hood shall be made of easily decontaminated materials, such as stainless steel plate or PVC plate. Acid resistant ceramic tile or stainless steel plate can be used at the bottom of the filter; Gas, hot and cold water and sewage outlets are set in the cabinet; The lighting standard is 150-300 LX, and the power socket is set outside the fume hood.

電動(dòng)推拉門、電動(dòng)平開門：門體鋼骨架結(jié)構(gòu)，上懸掛地軌兩種載荷方式，設(shè)計(jì)鉛當(dāng)量1-6mmpb，雙面外飾不銹鋼板或鋼塑板，鋁塑板等外飾面，配置:進(jìn)口、國(guó)產(chǎn)精密電腦控制電動(dòng)門機(jī)，紅外安全傳感器，光電限位，兩組固定按鈕，遙控開關(guān)，門機(jī)聯(lián)鎖，輻射警示標(biāo)志，工作指示燈。

Electric sliding door, electric swing door: steel frame structure of door body, two load modes of hanging ground rail, design lead equivalent of 1-6mmpb, double-sided external decoration of stainless steel plate or steel plastic plate, aluminum plastic plate and other external decoration, configuration: imported and domestic precision computer-controlled electric door machine, infrared safety sensor, photoelectric limit, two groups of fixed buttons, remote control switch, door machine interlocking, radiation warning signs, etc, Work indicator light.
