Manufacturing workshop removes dust the system delimits dispenses is designed

To a few production the workshop removes dust for, may need to handle the dust of different property, be about to notice them at this moment differentiate. If be in prepared herbal medicine in small pieces ready of decoction kind workshop of noxiousness prepared herbal medicine in small pieces ready of decoction is encountered with respect to the likelihood in the workshop, be about at this moment of workshop of prepared herbal medicine in small pieces ready of decoction of watchful general noxiousness remove dust make a system alone, want with otherThe workshop removes dust systemDelimit departure comes. Remove dust of the system differentiate should accord with following requirement:

1. With one production the flow, Yang Chen that works at the same time is nodded when apart is not big, appropriate closes for a system.

2. Work at the same time but the Yang Chen with dust different sort is nodded, allow different dust to mix when craft reclaim or dust is not had reclaim when value, also can close establish a system.

3. Temperature and humidity contains dirt gas differently, when the likelihood after should mixing brings about the knot inside wind canal to show, part of one’s job establishs a system.

　　 Remove dust in the design the following should notice when the system:

1. Remove dust the dot of the system that discharge wind is unfavorable and overmuch, with benefit each raise equilibrium of the block between the canal, the dot that be like a platoon is overmuch, canal of gather of usable large section joins each raise a canal, gather canal velocity of flow is unfavorable exceed 3m/s.

2. It is to prevent dust inside wind canal deposit, remove dust systematic wind is in charge of as far as possible perpendicular or tilt lay, tilt when laying, the included angle with horizontal had better be more than 45 ° , be like must when the level lays, need a setting to sweep a mouth.

3. Remove dust systematic air channel because wind speed is higher, use circular air channel normally, and the diameter is lesser. But, jam to prevent air channel, remove dust the diameter of air channel is unfavorable be less than following data: The platoon sends petty dust (mineral dust) ≥ 80mm; The platoon sends thicker dust (like wood chip) ≥ 100mm; The platoon sends meal this world (like paring) ≥ 130mm; The platoon sends hub ≥ 150mm.

4. Remove dust the hydraulic balance sex that systematic wind canal asks is good. Have hydraulic consideration to shunt-wound pipeline, average ventilated system asks the pressure loss difference of two canals does not exceed 15% , remove dust the pressure loss difference that the system asks two are in charge of does not exceed 10% , in order to make sure the wind force of each canal achieves design requirement.

5. The workshop removes dust the size of the wind speed inside systematic wind canal, besides wanting to consider to be affected to its system socioeconomic, cross path of zephyr of pairs of big equipment to wear away considering the wind speed inside wind canal even accelerate; Wind speed is too little, can make dust deposit again, jam conduit. Jam to prevent dust to be mixed in the deposit inside conduit, the wind speed inside the canal cannot is less than remove dust the lowermost air velocity of flow that standard of wind speed of systematic wind canal provides.
