Description
Technical field
The utility model relates to a kind of liquid waste treating apparatus, especially relates to a kind of waste liquid and mother liquid evaporation concentrating unit that contains viscous material.
Background technology
In sewage, waste liquid and mother liquor treating processes, adopt pump feed evaporator for the evaporation concentration of crystallization, viscous material more.Pump feed evaporator, the structure of promptly common evaporation concentration device comprise heating chamber 29, separate chamber 30 and propeller pump 28 as shown in Figure 2, and the heating tube in the heating chamber adopts the long tube single tube to arrange that the separate chamber is common bucket type separate chamber.Steam inlet 21, top are set on the top of heating chamber are provided with that material liquid outlet 24, bottom are provided with condensate outlet 22, the bottom is provided with liquor inlet 23; Be provided with at the top of separate chamber that secondary steam outlet 27, middle part are provided with overheated liquor inlet 25, the bottom is provided with and concentrates raffinate outlet 26; The material liquid outlet 24 of heating chamber is connected with the overheated liquor inlet 25 of separate chamber by pipeline; The concentrated raffinate outlet 26 of separate chamber is connected with propeller pump 28 by pipeline, and propeller pump 28 is connected with the liquor inlet 23 of heating chamber by pipeline.
The principle of work of common evaporation concentration device is: steam enters heating chamber by the steam inlet 21 that is arranged on heating chamber top, in shell and heating tube heat exchange condensation after be arranged on the condensate outlet 22 of heating chamber bottom and discharge; Feed liquid enters heating chamber by the liquor inlet 23 that is arranged on the heating chamber bottom, feed liquid process in heating chamber is heated as overheated feed liquid, discharge heating chamber by the material liquid outlet 24 that is arranged on the heating chamber top, enter the separate chamber through overheated liquor inlet 25 again, big raffinate of proportion and crystalline solid are discharged the separate chamber through the concentrated raffinate outlet 26 that is arranged on the bottom, separate chamber, and 28 circulations enter heating chamber through propeller pump again; Secondary steam is discharged the separate chamber through the secondary steam outlet 27 that is arranged on the top, separate chamber.
Because heating tube adopts the long tube single tube to arrange, go out on advancing under the feed liquid, for contain the fouling of organic viscous material heating tube or stop up very serious, and long tube to stop up the back cleaning difficult unusually; Because the separate chamber is common bucket type separate chamber, big raffinate of proportion and crystalline solid circulation enter heating tube, increase the heating tube latch up phenomenon easily.Therefore, for the bigger material of viscosity (as high salt high concentrated organic wastewater), in process of production, common evaporation concentration device is because the obstruction of heating chamber heating tube and cleaning difficulty usually cause vaporizer normally not move.
The utility model content
The utility model has overcome the shortcoming in the present technology, provides a kind of heating tube not susceptible to plugging evaporation concentration device.
The technical solution of the utility model is: a kind of evaporation concentration device, comprise heating chamber, separate chamber and propeller pump, described heating chamber is provided with mutual isolated admission chamber and goes out sap cavity in the bottom, admission chamber is respectively arranged with corresponding liquor inlet and material liquid outlet with the bottom that goes out sap cavity, there are some integral body to be the heating tube that inverted U is arranged in the heating chamber, the two-port of heating tube is communicated with admission chamber and goes out sap cavity respectively with admission chamber with go out the sap cavity cross-over connection.
Be provided with tangentially at the middle part of described separate chamber that overheated liquor inlet, middle and upper part are provided with purified liquor outlet, the bottom is provided with and concentrates the raffinate outlet; Described concentrated raffinate outlet is connected with propeller pump by valvular pipeline is set, and propeller pump is connected with concentration tank by valvular pipeline is set; Described purified liquor outlet is connected with propeller pump by valvular pipeline is set, and propeller pump is connected with the liquor inlet of heating chamber by pipeline.
Top at described heating chamber is provided with porthole.
Compared with prior art, the utility model has the advantages that:
1) because the heating tube of heating chamber is inverted U, compare single tube, same heated length interval, the height of inverted U heating tube has shortened half, is convenient to clean.
2) because the heating tube of heating chamber is inverted U, the crystalline solid gravitate is difficult for causing the obstruction of heating chamber in the bending part fouling.
3) heating tube of heating chamber adopts two-tube layouts of inverted U can energy efficient: if only adopt equal height single tube layout, under, the heat interchanging area controlled condition constant in treatment capacity, keep the consumption that velocity in pipes need strengthen the pump energy; Because the height of single tube is the twice of inverted U pipe, feed liquid is carried also need overcome more gravity acting, has increased the consumption of pump energy simultaneously.
4) because the middle part in the separate chamber tangentially is provided with overheated liquor inlet, middle and upper part purified liquor outlet, bottom are set are provided with and concentrate raffinate and export, made full use of the principle of cyclone structure, to the heavy phase of feed liquid with gently separate mutually, make big raffinate of proportion and crystalline solid enter the lower end, separate chamber, after propeller pump enters concentrated flow container, only surplus clear liquid circulation enters heating tube, greatly reduces the heating tube latch up phenomenon.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of common evaporation concentration device;
Fig. 3 is the cyclone structure schematic diagram of the utility model separate chamber.
