Description
Technical field
Drying column cone heating and a cooling device, belong to chemical liquid spray drying device field.
Background technology
Drying column cone is bottom at the bottom of the tower of drying tower; it is the visual plant that workshop granular material is collected; under because material directly pastes cone inwall; running quality and the product quality of the degree of drying of cone and the cooling protection degree direct influence tower in production process, cooling in the time of need to heating when drying tower for this reason, produce.Workshop drying column cone only adopts the type of cooling of middle part axial flow blower air-out, cone top and the bottom air intake at present.When cooling, by axial flow blower, from cone bottom and drying tower top, draw natural wind, from the air draft of cone middle part, cooling slowly and poor effect and top air-admitting surface be greater than bottom air-admitting surface, intensity of cooling is inadequate, has affected product quality.While drying tower air after air heater heating, deliver in drying tower and go downwards to cone middle and upper part after return cone upper, annular road, finally by air-introduced machine, by discharge pipe, send into main evacuated tube emptying, cone middle and lower part is mainly by radiant heat heating, drying.Because drying tower air outlet is on cone top, hot blast is difficult to arrive cone middle and lower part, and cone is dried slower, and thermal energy consumption is larger.
Summary of the invention
Technical problem solved by the invention is: overcome existing drying column cone heating and dried slower with cooling device, consume electric energy larger, cooling effect is not good, affects the problem of product quality, provides a kind of drying column cone more efficient, energy-conservation, good cooling results to heat and cooling device.
The technical scheme that technical solution problem of the present invention adopts is: this drying column cone heating and cooling device, comprise be fixed on drying tower bottom cone, be set in chuck at the bottom of the cone of cone bottom, main exhaust duct, the air-introduced machine that connects the discharge pipe of main exhaust duct and drying tower and be arranged on discharge pipe, it is characterized in that: the parallel beneath at discharge pipe arranges a blast pipe, blast pipe one end is connected with cone end chuck, the other end connects main exhaust duct, and discharge pipe is connected by pipeline with blast pipe.
On described blast pipe, air blast is installed, is played and send wind action.Between blast pipe and main exhaust duct, the second control valve is set, between discharge pipe and main exhaust duct, the first control valve is set, the 3rd control valve is set between discharge pipe and blast pipe, by regulating the switching of each control valve can adjust air force and circulation path.
Compared with prior art, the beneficial effect that the present invention has is:
1. save energy and reduce the cost, improve production capacity: because cone adopts drying tower self waste-heat, and it is cooling to quote natural wind, make to dry and cooling velocity obviously improves, drying tower feed intake in advance operation, saved a large amount of electric energy and heat energy, extended the cycle of operation, the production capacity of raising drying tower;
2. effectively guaranteed product quality: in the middle part of the upper and lower air inducing of the cooling employing axial flow blower of cone, the type of cooling of air-out is cooling forces cooling combining with air blast, good cooling results, cone is protected no longer overheated from bottom to top, has effectively guaranteed the quality of product.
Accompanying drawing explanation
Fig. 1 is a kind of drying column cone heating and cooling device structural representation.
Wherein: 1, cone 2, cone end chuck 3, blast pipe 4, air blast 5, the second control valve 6, main exhaust duct 7, the first control valve 8, the 3rd control valve 9, air-introduced machine 10, discharge pipe 11, drying tower.
Fig. 1 is most preferred embodiment of the present invention, and below in conjunction with accompanying drawing 1, the present invention will be further described:
The specific embodiment
With reference to accompanying drawing 1:
This kind of drying column cone heating and cooling device comprise be fixed on drying tower 11 bottoms cone 1, be set in chuck 2 at the bottom of the cone of cone 1 bottom, main exhaust duct 6, the air-introduced machine 9 that connects the discharge pipe 10 of main exhaust duct 6 and drying tower 11 and be arranged on discharge pipe 10, parallel beneath at discharge pipe 10 arranges a blast pipe 3, blast pipe 3 one end are connected with cone end chuck 2, the other end connects main exhaust duct 6, discharge pipe 10 is connected by pipeline with blast pipe 3, and main exhaust duct 6 is vertically placed.
The second control valve 5 is set between blast pipe 3 and main exhaust duct 6, the first control valve 7 is set between discharge pipe 10 and main exhaust duct 6, the 3rd control valve 8 is set, by regulating the switching of each control valve can adjust air force and circulation path between discharge pipe 10 and blast pipe 3.
Operation principle and the course of work are as follows:
The heating of this drying column cone and cooling device take full advantage of drying tower 11 self waste heat, by air-introduced machine 9 and air blast 4, hot blast is introduced to cone 1 bottom air inlet, hot blast is directly flutterred cone 1 outer wall heating fast, when cooling, utilize air blast 4 that natural wind is introduced to 3 pairs of cones 1 of blast pipe and force coolingly, and retain the type of cooling of the upper and lower air inducing of former axial flow blower middle part air-out.
During cone 1 heating, by the first control valve 7 in semi-closed state, the second control valve 5 close completely, the 3rd control valve 8 opens completely, air force is regulated by the first control valve 7.Air delivers in drying tower 11 after air heater heating, part hot blast is drawn by discharge pipe 10 by air-introduced machine 9 again, be incorporated into blast pipe 3, by air blast 4 work, hot blast is blowed to cone chuck 2 bottoms, the end, and discharge and heat by top, this mode of heating and former mode of heating carry out simultaneously, have accelerated drying rate.When cone 1 is cooling, the first control valve 7 opens to guarantee that production is carried out simultaneously, the second control valve 5 is opened completely, the 3rd control valve 8 cuts out completely completely, and air blast 4 is worked, natural wind is introduced to blast pipe 3 and passed into cone end chuck 2 by main exhaust duct 6, it is forced cooling, the former axial flow blower type of cooling is carried out simultaneously, has accelerated cooling velocity.
The above, be only preferred embodiment of the present invention, is not the present invention to be done to the restriction of other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
