Abstract
The utility model relates to a residual heat recovery energy-saving device used in the starch processing field, mainly used in starch drying field for recovering energy from the residual heat of exhaust gas. The device comprises a first fan (1), a heater (2), a dryer (3) and a second fan (4). Gas from the first fan (1) enters the cold side of a hot pipe heat exchanger (5), gas coming out of the cold side of the hot pipe heat exchanger (5) enters the heater (2), gas coming out of the heater (2) enters the dryer (3), exhaust gas coming out of the dryer (3) enters the hot side of the hot pipe heat exchanger (5), and gas coming out of the hot side of the hot pipe heat exchanger (5) enters the second fan (4). Heat is extracted from exhaust gas produced by starch drying technique, air is heated, and the heat of exhaust gas is utilized to the greatest extent; hot air is utilized in the drying technique again, so that heating hot source energy required by the heater is reduced, primary energy consumption is directly reduced, and purposes of energy saving and environment protection are achieved.
Description
(1) technical field
The utility model relates to a kind of waste heat recovering energy conserving device.Be used for the heat exchange of two kinds of gas with various media.Be mainly used in the UTILIZATION OF VESIDUAL HEAT IN energy recovery of dried tail gas in the dry field of starch.Belong to the heat-exchange equipment technical field.
(2) background technology
At present, the starch drying technology process that is used for the starch manufacture field as shown in Figure 1.As seen from Figure 1, starch exsiccant technological process is: the air of normal temperature enters heater heats through first blower fan, the effect thermal source entered moisture eliminator after temperature raise, dry starch, and the higher tail gas of the temperature that moisture eliminator produces directly is not discharged in the atmosphere through second blower fan through heat recovery, both wasted energy like this, envrionment temperature is uprised.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can recycle the waste heat recovering energy conserving device that is used for the starch manufacture field that the starch drying process produces heat in the tail gas.
The purpose of this utility model is achieved in that a kind of waste heat recovering energy conserving device that is used for the starch manufacture field, comprise first blower fan, well heater, moisture eliminator and second blower fan, the gas that first blower fan comes out inserts the hot tube heat exchanger cold side, the gas that the hot tube heat exchanger cold side comes out inserts well heater, the gas that well heater comes out inserts moisture eliminator, the moisture eliminator tail gas discharged inserts the hot side of hot tube heat exchanger, and the gas that the hot side of hot tube heat exchanger is come out inserts second blower fan.
The beneficial effects of the utility model are:
The utility model is by setting up a hot tube heat exchanger in the starch dehumidification system, utilize the phase transition of vacuum principle, be implemented in the heat exchange under the mutual isolated condition of fluid, the heat extraction that the starch drying process produces in the tail gas is come out, heated air simultaneously, utilized the heat of tail gas to greatest extent, join warm air in the drying process again, make that the heating heat-source energy of well heater is reduced, thereby primary energy consumption is reduced, reach the purpose of not only energy-conservation but also environmental protection.Simultaneously, power waste is little during the hot tube heat exchanger operation, does not have moving parts, the maintainability performance height.Device control simply is easy to realize, and is reliable and stable.
(4) description of drawings
Fig. 1 is starch drying technology process figure in the past.
Fig. 2 is used for the structural representation of the waste heat recovering energy conserving device of starch manufacture field for the utility model.
Reference numeral among the figure:
First blower fan 1, well heater 2, moisture eliminator 3, second blower fan 4, hot tube heat exchanger 5;
Normal temperature air temperature T 1, advance moisture eliminator hot air temperature T2, go out second blower fan exhaust temperature T3, advance the heat source temperature t1 of well heater, the heat source temperature t2 of from heater core.
(5) embodiment
Referring to Fig. 2, Fig. 2 is used for the structural representation of the waste heat recovering energy conserving device of starch manufacture field for the utility model.As seen from Figure 2, the utility model is used for the waste heat recovering energy conserving device of starch manufacture field, comprise first blower fan 1, well heater 2, moisture eliminator 3, second blower fan 4 and hot tube heat exchanger 5, the gas that first blower fan 1 comes out inserts hot tube heat exchanger 5 cold sides, the gas that hot tube heat exchanger 5 cold sides come out inserts well heater 2, the gas that well heater 2 comes out inserts moisture eliminator 3, and moisture eliminator 3 tail gas discharged insert hot tube heat exchanger 5 hot sides, and the gas that hot tube heat exchanger 5 hot sides are come out inserts second blower fan 4.
Principle of work:
The air of normal temperature heats up through the hot tube heat exchanger heat exchange, temperature raises about 30 ℃ after first blower fan enters heater heats by T1, temperature enters moisture eliminator as the heating pyrogen after being increased to T2, dry starch, and the higher tail gas of the temperature that moisture eliminator produces is lowered the temperature through the hot tube heat exchanger heat exchange, and temperature enters atmosphere after reducing about 35 ℃ by T3 again.
Claims (1)
1. waste heat recovering energy conserving device that is used for the starch manufacture field, comprise first blower fan (1), well heater (2), moisture eliminator (3) and second blower fan (4), the gas that first blower fan (1) comes out inserts hot tube heat exchanger (5) cold side, the gas that hot tube heat exchanger (5) cold side comes out inserts well heater (2), the gas that well heater (2) comes out inserts moisture eliminator (3), moisture eliminator (3) tail gas discharged inserts the hot side of hot tube heat exchanger (5), and the gas that the hot side of hot tube heat exchanger (5) is come out inserts second blower fan (4).
