DC scroll and AC reciprocating block multi circuit dryer

(I) get out of the "seven mistakes" of the traditional dryer: 1 In order to improve the output of the traditional dryer, the dryer drum is too long and the diameter is too large, which can not be fully utilized, resulting in the loss of heat energy, and the equipment covers a large area 2 In order to increase the output, the inlet temperature is too high and the outlet temperature is too high, which results in energy waste At the same time, it also causes the quality of the dried material to decline, the material color to turn black seriously, and even a lot of paste 3 Due to the low wind speed in the drum, the dynamic and static contact strength between the material and the hot air is relaxed, which results in the low drying efficiency of the equipment 4 Only in the downstream drying, and the saturated water vapor cannot be discharged in time during the drying process, so that the water vapor runs too long in the drum, causing the moisture to be reabsorbed by the dry material 5 Materials will not make "reciprocating motion" in the drum (the "reciprocating motion" and "square fast multi circuit motion" of materials in the equipment are two different concepts of our process flow) As a result, the storage capacity of the materials in the drum is too low, resulting in the reduction of the dynamic and static contact area between the materials and the hot air 6 In order to limit the flow speed of materials towards the outlet, only the rotation speed of the drum is limited to a very low level, so that the number of times the materials in the drum are lifted is greatly reduced Therefore, the dynamic contact times between materials and hot air are greatly reduced 7 It is an extreme error for the main engine to be installed in the form of high inlet end and low remote end Because this installation method can only speed up the flow of materials to the far fire end, so that the storage capacity of materials in the drum is reduced again From the front to the back of the whole drum, the lifting plates are lifting materials at the same time, but the lifting materials are few For example, when a traditional dryer with a length of more than 20 meters is in normal production, a clear flame can be seen from the observation port of the main engine This shows that there are few materials in the drum, the space utilization rate of the drum is very low, and a lot of heat energy is lost At the same time, this design creates unnecessary obstacles to the installation and operation of the equipment Because the host with tilt angle must be installed with a set of anti-skid roller to fix it when it is installed, so as to prevent the equipment from sliding down in operation, which is very troublesome The so-called "seven mistakes" above are the fatal weaknesses of low output, high cost, large loss of heat energy and poor quality of finished products of traditional dryers (2) "five big" strange phenomena in the production of the drying technology of the new process of gold: 1 The outlet temperature of the drying machine of gold is below 30 ℃ to produce the finished product as usual 2 The quality and color of the finished product can be comparable to that of the tube bundle dryer This is beyond the reach of any direct heat dryer 3 When the equipment is in normal production, no fire can be seen from the observation port of the main engine Even Zui's small equipment rollers are only 3 meters long This phenomenon shows that there are a lot of materials stored in the drum All the spaces of the drum are occupied by the materials raised by the lifting plate The fire light of the main fire port is strictly blocked by the materials, so nothing can be seen All the heat is fully utilized 4 In case of sudden power failure in normal production of the equipment, the operator does not need to take any stress measures to prevent fire in the drum This phenomenon shows that the temperature in the drying drum of the gold dryer is very low, and the operation according to the regulations will not cause fire 5 For the dryer of the same scale, the air speed in the drum of the gold dryer is about 50% higher than that in the drum of the traditional dryer, but the storage capacity of materials is more than doubled instead of being reduced This phenomenon is due to the "reciprocating motion" of materials, and has nothing to do with the "multi loop motion" of materials The above example is the inevitable result after the gold dryer has changed the seven technical errors of the traditional dryer (3) special dryers for corn syrup, amino acid tail liquor, monosodium glutamate tail liquor and insoluble industrial tail liquor: The insoluble industrial tail liquid, such as corn syrup, amino acid tail liquid and monosodium glutamate tail liquid, is a kind of discharge liquid in the production process of fermentation industry For example, the solid content rate after concentration is generally between 15-14% At present, the drying of this industrial tail liquid is a worldwide problem The special dryer developed and produced by our company can directly dry it into grains, Have independent intellectual property rights Drying object: with the development of feed industry and organic agriculture, alcohol residue, medicine residue, white wine residue, beer residue, starch residue, fruit residue, etc have gradually become important raw materials for feed, organic fertilizer manufacturing and other related enterprises Many dregs have the characteristics of high viscosity, high water content, large oil content and variable properties The traditional dryer is difficult to complete the drying at one time, and has many component losses and high cost, so it can not adapt to the treatment of this kind of dregs In view of this situation, "1-1 ≠ 0" energy-saving drying engineering science and technology research department Zui newly developed the "DC vortex plus AC reciprocating block multi circuit" dryer, which can dry the finished products at one time and control the water content below 12%, with advanced performance indicators, reasonable design, energy conservation and environmental protection, innovation, and technology level ranking first in the world
