Abstract
The utility model relates to an evaporating apparatus utilizing process waste gas as a heat source, which belongs to a liquid concentrating apparatus. The utility model comprises a heat exchanging evaporation tower which is provided with a clamping sleeve and a tube, wherein, a washing tower is arranged before the heat exchanging evaporation tower, the washing tower is connected with the pipeline of an inlet pipe for the shell heat source, the inlet pipe for the shell heat source is arranged on the upper part of the heat exchanging evaporation tower, a blower is arranged on an outlet pipe for the shell heat source, and the outlet pipe for the shell heat source is arranged on the lower part of the heat exchanging evaporation tower. The utility model can preprocess process heat waste gas through the washing tower, the detention of the waste gas in the heat changing evaporation tower can be solved by using the blower, the concentration evaporation process by using the waste gas as the heat source can be implemented, and the cost can be saved.
Description
Technical field
The utility model belongs to liquid concentrator, be meant especially by chuck and tubulation carry out heat exchange, be the liquid evaporation equipment of thermal source with operation waste gas.
Technical background
Corn steep liquor extracts in the technology of humic acid after liquid-solid separation, filtrate is carried out concentration and evaporation, the equipment of selecting for use is generally the heat exchange tower of strap clamp cover and tubulation, provide thermal source with water vapour, technology is ripe, but the waste gas that produces 80-90 ℃ owing to this technology preorder discharges in vain, and the waste thermal source makes the cost of final products increase.Also the someone considers with the tube bank waste gas of this technology thermal source as heat exchanger, but because deacration also includes dust outward in the waste gas, organic substance particle and acid, dust and particle are attached to tube wall easily, reduce heat transfer coefficient, influence heat-transfer effect, acid also has corrosiveness to pipeline, in addition, make thermal source, because of it is an air with waste gas, in diabatic process, there is not phase transformation, Volume Changes is little and pressure air is not high, and the thermal source air in the heat exchange evaporating column easily is detained, and for the heat exchange evaporating column of equal volume, the demand of hot-air is bigger, and retention problems has limited the utilization again of hot waste gas.
Summary of the invention
The utility model is at above-mentioned deficiency, providing a kind of is thermal source carries out evaporation and concentration to filtrate equipment with the hot waste gas that produces in the technology, solved the delay of waste gas in the heat exchange evaporating column, avoided the deposition of dust and particle simultaneously, guaranteed heat-transfer effect, its improvements are to be provided with an exhaust gas washing tower before the heat exchange evaporating column, by preliminary treatment to tube bank waste gas, remove the acid in it, dust and organic substance particle, thereby avoided waste gas directly to advance corrosion and deposition affects that the heat exchange evaporating column brings, in time discharge in order to make the gas in the heat exchange evaporating column, the utility model is provided with a blower fan on the waste gas outlet pipeline of tower hypomere, the air in the tower body is discharged in pressure, finishes heat exchanging process.Specifically implement like this: a kind of is the evaporation equipment of thermal source with operation waste gas, the heat exchange evaporating column that comprises strap clamp cover and tubulation, its feature is equipped with a scrubbing tower before the heat exchange evaporating column, the shell thermal source air inlet pipe pipeline on described scrubbing tower and heat exchange evaporating column top joins, and the shell thermal source of heat exchange evaporating column bottom goes out to be equipped with a blower fan on the pipe.Be provided with scrubbing tower just, make the waste gas in the operation carry out preliminary treatment earlier, remove disadvantage factor, just make waste gas might make the thermal source of evaporating column, adding of blower fan can make the timely emptying of air in the evaporating column, necessary enough heats in time are provided, make operation be able to normal operation.Utilizing waste gas for thermal source carries out heat exchange to the filtrate evaporation and concentration, is to the utilization again of whole technology waste resource, need not to increase extra a large amount of water vapour, has fundamentally reduced cost.
Because of making thermal source with waste gas, on-condensible gas in the heat exchange evaporating column gathers easily, form the dead band, influence heat exchange effect, in order to guarantee the available heat exchange process in the evaporating column, reach the filtrate out temperature of design, the utility model is with the non-homogeneous discharging of the deflection plate in the heat exchange evaporating column, just the spacing between deflection plate progressively increases from bottom to up, the baffle(s) spacing of cat head maximum be the baffle(s) spacing of minimum at the bottom of the tower 1.5-2 doubly.
The utility model just by scrubbing tower to the preliminary treatment of process heat waste gas, solve the delay of waste gas in the heat exchange evaporating column with blower fan, making utilizes waste gas to be implemented for the technology that thermal source carries out concentration and evaporation, saved cost greatly, the non-homogeneous setting of the deflection plate in the heat exchange evaporating column, make on-condensible gas in tower, to form the dead band, guaranteed effective heat exchanging process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the artwork of deflection plate in the utility model tower body.
The specific embodiment
A kind of is the evaporation equipment of thermal source with operation waste gas, the heat exchange evaporating column (1) that comprises strap clamp cover and tubulation, the preceding scrubbing tower (2) that is equipped with of heat exchange evaporating column (1), scrubbing tower (2) joins with the shell thermal source air inlet pipe pipeline on heat exchange evaporating column top, the shell thermal source of heat exchange evaporating column (1) bottom goes out to be equipped with on the pipe blower fan (3), deflection plate (4) spacing in the heat exchange evaporating column (1) progressively increases from bottom to up, and the deflection plate of cat head maximum (4) spacing is 1.5 times of deflection plate (4) spacing of minimum at the bottom of the tower.
Claims (3)
1. one kind is the evaporation equipment of thermal source with operation waste gas, the heat exchange evaporating column that comprises strap clamp cover and tubulation, its feature is equipped with a scrubbing tower before the heat exchange evaporating column, the shell thermal source air inlet pipe pipeline on described scrubbing tower and heat exchange evaporating column top joins, and the shell thermal source of heat exchange evaporating column bottom goes out to be equipped with a blower fan on the pipe.
2. evaporation equipment according to claim 1 is characterized in that the baffle(s) spacing in the heat exchange evaporating column progressively increases from bottom to up.
