Abstract
The utility model relates to a recovery device of waste heat by means of spray drying in PVP technic. The technical proposal is as follows: a blower is connected with a recoverer of waste heat, and is then connected with a steam heater, an electric heater and a drying tower in turn; the top part inside the drying tower is provided with a hot air distributer the lower part of which is provided with the spray gun head of a high pressure charging system, and the bottom end of the drying tower is connected with a big bag filter; the top of the big bag filter is connected with the recoverer of waste heat and an induced draught fan in turn, and the bottom of the big bag filter is connected with a cooling air water eliminator and a small bag filter; the top of the small bag filter is connected with a cooling blower and the bottom of the small bag filter is connected with a barrel filling device. The utility model has the beneficial effects that the hot air, which is generated from the temperature-falling period of gas-solid separation, is used for preheating the air in an air preheater, thus increasing the air temperature, decreasing the requirement for energy during the next procedure, making full use of the energy and realizing the energy conservation.
Description
One, technical field:
The utility model relates to a kind of spray-drying installation in a kind of PVP technology, particularly relates to a kind of spray-drying waste-heat recovery device.
Two, background technology:
In PVP technology, spray-drying is to make the liquid material that contains solid enter the process that drying medium changes powder into through spraying, spray-drying generally is divided into 4 stages: feed liquid is carried and atomizing, hot-air entering and with the material mist contact, the drying (evaporation of moisture content or other volatile materials) of material mist, the dry powder goods separate from air and reclaim.Now, the manufacturer of most of spray-drying installation and use producer less than to drawing attention with the air after the dry powder goods separate and the heat that mist contained of solvent, manufacturer does not design heat recovery equipment in manufacturing process, use producer in use directly the gas of this part higher temperature directly to be emitted, caused a large amount of wastes of the energy.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of spray-drying waste-heat recovery device is provided, mixed gas after the employing gas solid separation enters the waste-heat recoverer from the separator top, cold air is carried out waste heat recovery and preliminary preheating, reach further recycling and purpose of energy saving of waste heat.
Its technical scheme is: mainly be made of air blast, steam heater, electric heater, drying tower, hot-air distributor, high pressure charging system, big bag hose, cooling air dehydrater, little bag hose and cooling blower, described air blast is connecting waste-heat recoverer, and the back is connecting steam heater, electric heater, drying tower successively; At the drying tower inner top hot-air distributor is arranged, hot-air distributor bottom is the lance head of high pressure charging system, and the drying tower bottom connects big bag hose; The top of big bag hose connects waste-heat recoverer and air-introduced machine successively, and the bottom links to each other with little bag hose with the cooling air dehydrater; Pouch filter top connects cooling blower, and the bottom connects barrelling equipment.
And the connection corresponding with air blast and steam heater of a flow process of above-mentioned waste-heat recoverer, another flow process is with big bag hose and air-introduced machine is corresponding and connection.
The beneficial effects of the utility model are: the hot-air that carries out in the utilization producing in the gas solid separation temperature-fall period carries out preheating to the air in the air preheater, has improved the temperature of air, reduces the demand of energy in next step operation; Energy is carried out sufficient utilization, reached purpose of energy saving.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is: mainly be made of air blast 1, steam heater 2, electric heater 3, drying tower 4, hot-air distributor 5, high pressure charging system 6, big bag hose 7, cooling air dehydrater 10, pouch filter 11 and cooling blower 12, described air blast 1 is connecting waste-heat recoverer 9, and the back is connecting steam heater 2, electric heater 3, drying tower 4 successively; At the drying tower inner top hot-air distributor 5 is arranged, hot-air distributor 5 bottoms are lance heads of high pressure charging system 6, and the drying tower bottom connects big bag hose 7; The top of big bag hose 7 connects waste-heat recoverer 9 and air-introduced machine 8 successively, and the bottom links to each other with pouch filter 11 with cooling air dehydrater 10; Pouch filter 11 tops connect cooling blower 12, and the bottom connects barrelling equipment.
Wherein, flow process of waste-heat recoverer 9 and air blast 1 and steam heater 2 are corresponding and be communicated with another flow process and big bag hose 7 and air-introduced machine 8 corresponding and connections.
Its course of work is as follows: air blast 1 is sent cold air to waste-heat recoverer 9 preliminary preheatings, then enters steam heater 2 and is heated to uniform temperature, enters drying tower 4 after being adjusted to required temperature by electric heater 3 again; After entering the hot-air distributor 5 of hot-airs by drying tower 4 tops in the drying tower 4 and evenly distributing, contact, it is carried out drying, solvent is vaporized with the material of lance head atomizing by high pressure charging system 6; Powder material behind drying tower 4 inner dryings and mist enter big bag hose 7 by bottom line, in big bag hose 7, carry out gas solid separation, mixed gas after the separation is taken emptying away by air-introduced machine 8 after the discharge of big bag hose 7 tops enters waste-heat recoverer 9 and cold air heat exchange, and the pressure of being regulated in drying tower 4 and the big bag hose 7 by air-introduced machine 8 is in negative pressure state all the time, powder material after the separation is discharged from big bag hose 7 bottom discharge mouths, brings pouch filter 11 into after the cooling air cooling cooling after dewatering by cooling air dehydrater 10; Cooling air and powder material are in pouch filter 11, cooling air after the separation is taken emptying from pouch filter 11 tops away by cooling blower 12, cooling blower 12 is controlled pressure and the air quantity in the pouch filter 11 simultaneously, the powder material after the separation from pouch filter 11 bottom discharge pipes to the barrelling of barrelling equipment.
