Abstract
The utility model discloses an improved spray drying device suitable for material drying in food, chemical, pharmaceutical, feed and other industries. The improved spray drying device comprises a spray nozzle and a material pipeline. A high pressure air pipe with a direction identical with the material flow direction is arranged on the material pipeline near the spray nozzle of a centrifugal spray drying device or a pressure spray drying device, and high pressure airflow drives the material to be sprayed out of the spray nozzle at high speed, so as to facilitate material atomization of traditional equipment. The improved spray drying device adopts airflow spraying technology which is one of the most effective ways to dry high-viscosity material, and can effectively solve conveying and drying difficulties of high-viscosity and high-solid content material, in combination with centrifugal spray drying or pressure spray drying method. Compared with the traditional method, under the same condition, the improved spray drying device improves production capacity by more than 15 percent, reduces heat energy consumption by more than 1/3 and reduces outlet air temperature, and improves adaptability. The improved spray drying device can treat low-moisture content or high-solid content material, and is compatible to the traditional process methods.
Description
One, technical field
The utility model relates to a kind of spray-drying installation, is applicable to the drying of industry materials such as food, chemical industry, medicine, feed.
Two, background technology
Spray drying system generally is made up of air blast, air cleaner, air heater, spray tower, cyclone separator (or sack cleaner), air-introduced machine, dehvery pump etc., and connected mode is as follows: air blast, air cleaner, air heater, spray tower, cyclone separator (or sack cleaner) are connected successively with air-introduced machine.Material enters spray tower through dehvery pump, isolates dry material through cyclone separator (or sack cleaner) again after the drying.
Spray-drying mainly contains centrifugal spray, press atomization and three kinds of modes of air-stream spraying.Centrifugal spray is to utilize centrifugation to reach the material atomizing; Press atomization is to utilize the pressure of high-pressure pump to reach the material atomizing; Air-stream spraying is to utilize the flow velocity of pressure-air to reach the material atomizing.Centrifugal spray, press atomization are present two kinds of methods relatively more commonly used, and equipment has a common trend: for improving production capacity, reach atomizing effect simultaneously, the volume of equipment is more and more huger, and this all proposes requirements at the higher level to equipment manufacturing cost, factory building capital construction.Simultaneously, centrifugal spray commonly used and high-pressure fog equipment to the raw material of high viscosity or high solid content carry and dry aspect can not effectively solve, can only hang down with regard to spraying apparatus by adding solution or other material that can reduce viscosity, so both cause equipment capacity low, caused the heat energy significant wastage again; If centrifugal spray requires also corresponding raising to the shower nozzle motor properties.
Three, summary of the invention
The purpose of this utility model provides a kind of modified spray-drying installation, in the dry difficult problem of existing equipment and technical solution high viscosity, high solid content raw material, improve equipment production capacity, reduce energy resource consumption, and then reduce production costs.
The technical solution of the utility model is: the modified spray-drying installation comprises shower nozzle and material pipe, it is the high-pressure air tube consistent with flow direction of material of packing near the material pipe the shower nozzle of centrifugal spray drying device or pressure spray dryer device, make high pressure draught drive material, assist and finish the atomizing of legacy equipment material at a high speed by the spout ejection.
We know that high pressure draught has high linear velocity when discharging.Air-stream spraying technology and traditional centrifugal spray or press atomization are integrated, just can greatly improve the atomizing ability of existing equipment.
In general, pressure can reach several air pressure, and the linear velocity that discharges gas just can reach per second more than 100 meters, and is just fine to the effect that material disperses.
The utility model has been used the air-stream spraying technology, and the air-stream spraying technology is one of efficient ways that solves the high-viscosity material drying, it combines with centrifugal spray drying or pressure spray dryer method, can solve difficult problems such as high viscosity, high solid content mass transport, drying effectively.The contrast conventional method, the utility model has following change:
The first, production capacity greatly improves.Under equal conditions (promptly not changing under the condition of firing equipment, material moisture) production capacity can improve more than 50%; If strengthen heating efficiency, reduce material moisture, capacity of equipment improves more.This helps reduction and one-time fixes assets investment.
The second, energy consumption reduces significantly.Reach the drying effect that needs, thermal energy consumption reduces more than 1/3rd, and leaving air temp also decreases.This had both helped environmental protection, and it is convenient to help the packing of product again.
Three, reach the atomizing effect of peer-level, the rotating speed of centrifugal energy nozzle or the pressure of high-pressure nozzle all reduce greatly, and promptly the intensity of equipment operation reduces greatly.Prolong this running safety and service life that helps equipment.
Four, improve the adaptive capacity of equipment, can handle the material of low moisture content or high solid content, simultaneously traditional process is had compatibility.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model, and shower nozzle is a centrifugal energy nozzle;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model, and shower nozzle is a high-pressure nozzle.
Five, the specific embodiment
The modified spray-drying installation is the device that adds air-stream spraying on traditional centrifugal spray drying device or pressure spray dryer device, it comprises shower nozzle 1 and material channel 2, the high-pressure air tube consistent with flow direction of material 3 of packing near the material pipe the shower nozzle 12 has check valve 4 on high-pressure air tube 3.The utility model can be used for centrifugal spray equipment, and shower nozzle 1 is a centrifugal energy nozzle, also can be used for press atomization equipment, and shower nozzle 1 is a high-pressure nozzle.
