Abstract

The utility model discloses a kind of triple effect evaporators, including tank body, demister is provided in the tank body, the tank body side is provided with overflow nozzle and circulation water inlet, the overflow nozzle is located at below demister, the tank body top is additionally provided with vacuum nozzle, and tank body bottom end is provided with circulating water outlet.The utility model has the advantages that: after strict calculating and a large amount of experimental verification, in tank body side, overflow nozzle is arranged in demister lower position, liquid level reaches the i.e. automatic spilling of overflow nozzle, liquid level highest point can be effectively controlled, generation the case where Liquid level distortion failure caused by being avoided completely because of high solids after high-salt wastewater concentration and condition of high vacuum degree, so that the normal operation of triple effect evaporation system be effectively ensured.

Description

A kind of triple effect evaporator
Technical field
The utility model relates to field of chemical equipment, and in particular to a kind of triple effect evaporator.
Background technique
Triple effect evaporator extracts concentrator, and using the hot working principle of circulation, external, physics heated time is short, evaporation is fast Degree is fast, cocnentration factor is great, effectively keeps material original effect, energy-saving effect is significant, is suitable for pharmacy, chemical industry, food, light industry etc. extensively Liquid material evaporating and concentrating process process, the triple effect used in our company is original for the concentration and evaporation of high-salt wastewater steams Device is sent out, triple effect evaporator tank level control system therein is in use because of high solids and high vacuum after high-salt wastewater concentration Degree causes Liquid level to be distorted failure, to cause high liquid level slug and influence the normal operation of triple effect evaporator system.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of triple effect evaporator, overflow pipe is set on tank body Mouthful, liquid level highest point is effectively controlled, so that the normal operation of triple effect evaporation system be effectively ensured.
The technical solution adopted in the utility model is:
A kind of triple effect evaporator, including tank body are provided with demister in the tank body, and the tank body side is provided with overflow Nozzle and circulation water inlet, the overflow nozzle are located at below demister, and the tank body top is additionally provided with vacuum nozzle, tank body Bottom end is provided with circulating water outlet.
Further, the demister is whirlwind demister.
Further, the tank body side is additionally provided with liquidometer.
Further, it is additionally provided with vacuum pumping pump above the vacuum nozzle, the vacuum pumping pump is connected with vacuum nozzle It is logical.
Further, further include three-effect heat exchanger, be connected respectively by pipeline with circulating water outlet and circulation water inlet.
Further, the circulating water outlet is located at below liquidometer.
The beneficial effects of the utility model are: being removed after strict calculating and a large amount of experimental verification in tank body side Overflow nozzle is arranged in foam device lower position, and liquid level reaches the i.e. automatic spilling of overflow nozzle, liquid level highest point can be effectively controlled, completely Generation the case where Liquid level distortion failure caused by avoiding because of high solids after high-salt wastewater concentration and condition of high vacuum degree, to have Effect guarantees the normal operation of triple effect evaporation system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1, tank body, 2, demister, 3, liquidometer, 4, vacuum pumping pump, 5, three-effect heat exchanger, 11, overflow nozzle, 12, Recycle water inlet, 13, vacuum nozzle, 14, circulating water outlet.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to the protection scope of the utility model.
As shown in Figure 1, a kind of triple effect evaporator, including tank body 1 and three-effect heat exchanger 5, it is provided with demister 2 in tank body 1, Demister 2 is whirlwind demister, and 1 side of tank body is provided with overflow nozzle 11 and circulation water inlet 12, and overflow nozzle 11, which is located at, to be removed 2 lower section of foam device, bottom end are provided with circulating water outlet 14, and top is provided with vacuum nozzle 13, is additionally provided with above vacuum nozzle 13 Vacuum pumping pump 4, vacuum pumping pump 4 are connected with vacuum nozzle 13, further include three-effect heat exchanger 5, and three-effect heat exchanger 5 passes through pipe respectively Road is connected with circulating water outlet 14 and circulation water inlet 12, and 1 side of tank body is additionally provided with liquidometer 3, and 3 top of liquidometer is located at 11 lower section of overflow nozzle, circulating water outlet 14 are located at 3 lower section of liquidometer.
A kind of above-mentioned triple effect evaporator, for evaporate from two effect evaporators flow into high-salt wastewater when, from 1 bottom end of tank body Circulating water outlet 14 flows out, and flows into tank body 1 after the heating of three-effect heat exchanger 5 from circulation water inlet 12, and constantly circulation is gone down, Under the thermal energy effect of three-effect heat exchanger 5, the moisture in high-salt wastewater is evaporated, under the action of vacuum pumping pump 13, evaporation Moisture out is extracted out through whirlwind demister 2 from vacuum nozzle 13, the small Particle salt through being mingled in vapor when whirlwind demister 2 Divide and intercepted by whirlwind demister 2, ensure that the degree of purity of the vapor of extraction, in the process, passes through liquidometer 3 and observe tank Liquid level in body 1, by liquid level indirectly to the concentration and internal circulating load of the high-salt wastewater in the evaporation process in tank body 1 It is calculated and is controlled, the position height of overflow nozzle 11 is obtained by tightly calculating with after lot of experiment validation, is a pole End position point when the high-salt wastewater liquid level in tank body 1 is higher than this, just easily occurs Liquid level and is distorted failure situation, evaporated Once in journey liquid level reach 11 position of overflow nozzle at, then stoste pool is flowed out to from overflow nozzle 11 automatically, avoid completely because Occur the case where Liquid level distortion failure caused by high solids and condition of high vacuum degree after high-salt wastewater concentration, to be effectively ensured The normal operation of triple effect evaporation system, the salt analysis constantly as moisture is all evaporated during circulation, in high-salt wastewater Out.
