Description
Technical field
The invention belongs to and need to come drying solid material or arts by heating means, be specifically related to a kind of method of work of Ethyl vanillin production drier.
Background technology
Fluidizing fluid-bed drier is drying equipment granular solids being carried out to heating and dehumidification, use fluidizing fluid-bed drier can the solid of dry fine granularity, by hot-air from bottom to top, solid particle is upwards blown afloat, form the effect of similar liquids boiling, ensure that particle removes moisture while can not boning.
Fluidizing fluid-bed drier narrow application range of the prior art; generally be used for processing the solid particle between crystalline particle 30um-6mm; and the larger solid particle of viscosity can not be suitable for; when processing the solid particle that particle is too small, viscosity is excessive; easily make wallop be difficult to be formed because of boning between solid particle; the easy conglomeration of particle becomes block; affect drying effect; simultaneously; part can be bonded at furnace wall by the particle blown afloat; usual needs are manual after operation completes to be struck off, and not only causes waste, also have impact on production efficiency.
Ethyl vanillin in Chemical Manufacture is a kind of granule crystallization, particle < 30um, and viscosity is large, is easy to be bonded on the inwall of drier.The method that existing removing is bonded in the bourbonal on drier inwall needs manual after operation completes striking off usually, not only causes waste, also have impact on production efficiency.
Also have at present and adopt other modes to carry out clearing up, if patent announcement number is in the ethyl vanillin bubbling fluidized bed dryer of CN201666712U, longitudinal center line along wall is provided with rotating shaft, described rotating shaft is fixedly installed stirring vane, described stirring vane is fixedly installed scraper plate away from rotation axle head, described scraper plate coordinates with wall clearances, and described scraper plate is made up of silica gel plate.By scraper plate, the bourbonal particle be bonded on drier inwall is scraped, but in the process of scraper plate rotation, bourbonal drying blowout can be hindered, and additionally establish the Method compare of scraper plate to bother.
Summary of the invention
The object of the present invention is to provide a kind of method of work of Ethyl vanillin production drier, this method of work does not need labor cleaning to be bonded in bourbonal particle on drier inwall, and can not hinder the dried blowout of bourbonal.
For achieving the above object, base case of the present invention is as follows:
A method of work for Ethyl vanillin production drier, comprises dryer shell, is provided with inner casing in described dryer shell, and t/R≤0.05 of this inner casing forms airtight cavity between described inner casing and dryer shell; Also be provided with pump and liquid reserve tank, described liquid reserve tank is connected by pipeline with between dryer shell, and this pipeline is communicated with airtight cavity, and described pump is arranged on pipeline;
Described drier method of work comprises:
(1) bourbonal is blown afloat by hot-air from bottom to top in dry, and part bourbonal particle is bonded on dryer shell inwall;
(2) start pump, the liquid in liquid reserve tank pumps in airtight cavity by pipeline by pump, the pressure increase in airtight cavity, until make inner casing be out of shape;
(3), after inner casing distortion, the bourbonal particle detachment on inner casing inwall is bonded at.
In this programme, wherein t is the thickness of inner casing, and R is the radius of curvature in face in inner casing, and in inner casing, face refers to the curved surface dividing thickness of shell equally.
The principle of this programme and advantage: in use, in drier, solid particle is upwards blown afloat by hot-air from bottom to top by Ethyl vanillin, part can be bonded on the inwall of inner casing by the Ethyl vanillin particle blown afloat, be stained with more Ethyl vanillin particle on the inwall of inner casing after, start pump, by pump to pumping liquid in the cavity between dryer shell and inner casing, due to t/R≤0.05 of inner casing, inner casing belongs to shell, after pressure in cavity raises, inner casing generation deformation can be made, because the Ethyl vanillin be bonded on inner casing is solid-state, once there is deformation in inner casing, the bourbonal be bonded on inner casing inwall just can be made to come off from inner casing inwall, so just do not need the Ethyl vanillin on later stage labor cleaning drier inwall, use convenient.In addition, this programme is distortion by inner casing thus the bourbonal be bonded on inner casing inwall is come off, and rotates compared with the mode of clearing up by scraper plate in background technology, and dried bourbonal obviously can not be hindered to be blown.
Prioritization scheme 1, to the further optimization of base case, also comprise controller and the pressure sensor for detecting pressure in airtight cavity, described pump, pressure sensor are all electrically connected with controller; Described method of work also comprises pressure sensor by the pressure signal transmission that detects in controller, and when pressure reaches the numerical value of controller setting, controller control pump stops.
In the method for work of this programme, controlled the pressure in airtight cavity by pressure sensor and controller, set suitable pressure by controller and erect numerical value, the pressure in airtight cavity is too small, then the distortion of inner casing is little, and the bourbonal be bonded on inner casing inwall can be caused to come off; Pressure in airtight cavity is excessive, then the distortion of inner casing is excessive, and the distortion of inner casing can be caused to recover.So the too small and excessive problem brought of the pressure in airtight cavity can be prevented.
Prioritization scheme 2, to the further optimization of base case, in described method of work, starts Primary pumps in interval 2-3 hour.In use find, often cross 2-3 hour, inner casing inwall will bond one deck bourbonal, clears up so started Primary pumps at interval of 2-3 hour, and starts continuously compared with pump, more can save the energy.
Prioritization scheme 3, to the further optimization of base case, any one of prioritization scheme 1,2, the inwall of described inner casing is provided with some projections, and some projections distribute as net shape on the inwall of inner casing.After the inwall of inner casing is provided with projection, when inner casing deforms, the projection on inner casing inwall can apply the power of extruding to the bourbonal be bonded on inner casing inwall, the bourbonal particle be bonded on inner casing inwall more easily comes off.
Prioritization scheme 4, to the further optimization of prioritization scheme 3, the shape of described projection is prismatic, in the process of inner casing generation deformation, on the bourbonal that projection can be made to be applied on inner casing inwall, the power of local is larger, more easily makes the bourbonal of bonding split and come off.
