1, inwall is in the normal temperature state discharge cover starting stage, and is a large amount of when effluxing steam when touching, and will form condensed water and long-pending revealing at the inwall of discharge cover.
2, in the process of humidity discharging system work, because during the humidity discharging of discharge cover, the moisture-eliminating blower on top is done steam discharge work, so, the external ambient airflow in discharge cover exit will add in the discharge cover endlessly because of the inner journey negative pressure state of discharge cover, vapor stream blending, the mixing higher with temperature, form cold and hot convection current situation, make the vapor (steam) temperature be discharged from reduce, form cooling water and produce the long-pending phenomenon of revealing.
3, in humidity discharging system work, because of the humidity discharging pipe longer, particularly this humidity discharging pipe must be hinged with more than the roofing of factory or beyond the metope, because of being subjected to the external environment condition climatic influences, when this humidity discharging pipe inherence effluxes steam, also can form the cold ponding of part, and be back to the inwall of discharge cover along with the humidity discharging inside pipe wall to the discharging cover.
Thus, flashing apparatus is the exit of this hood in process of production, all the time constantly there is cooling water to wander the stem in this discharge cover exit from the inwall of hood, stem in the motion is after the immersion that is subjected to cooling water, form the caking of water stain wet group or wet group gradually, and be transported in the fluidized drying machine by the technology groove that shakes, because the stem water content of this water stain wet group is very big, though through the dry processing of fluidized drying machine, can not be dried into the stem that contains qualified moisture, still become the group of wetting or caking state from fluidized drying machine exit, even the water content of this part stem is still very big, in company with carrying out selection by winnowing in the winnowing machine that together is transported to stem by the normal stem after the oven dry, the stem that this part water content is very big after selection by winnowing flow in the container of collecting stalk label and stalk piece, because the stem of this part can not well be utilized, certainly will cause immeasurable loss and waste to enterprise, simultaneously, because the very big stem of this partially aqueous amount is when the Moisture Meter place of the online detection of flowing through, because the control of the moisture of stem is exactly in time to feed back to control program after relying on this Moisture Meter to detect in the ordinary production, again by the size of control program according to the real-time moisture of this stem, follow the tracks of control and reach the quality index requirement, yet because the very big stem of this part moisture is detected by Moisture Meter, control system will be carried out frequent adjustment, make the moisture of cut stem in control procedure present labile state, finally can cause descending in the up-to-standard rate of goods stem.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide the heating water trap in a kind of stem processing flashing apparatus, in the hope of the condensing water vapor that flash distillation discharging opening inwall is formed, avoids condensed water to fall into stem.
