Description

Technical Field

[0001] The utility model belongs to the technical field of sewage evaporation treatment, in particular to an integrated low-temperature evaporator. Background Art

[0002] Wastewater evaporation is a method of purifying wastewater by evaporating the water in it. This treatment method is usually suitable for wastewater containing a large amount of water, such as concentrated sludge, industrial wastewater, etc. During the wastewater evaporation process, the water in the wastewater is evaporated by heating or other methods, and the remaining part is concentrated into a smaller volume, which is easy to handle or dispose of later. The advantages of wastewater evaporation include effectively reducing the volume of sludge or wastewater, improving treatment efficiency, and reducing the impact of wastewater on the environment.

[0003] In the existing sewage evaporation treatment process, the sewage to be treated is not preheated, the heating requires a lot of energy, and the economy is not high. At the same time, after the evaporation is completed, the viscous waste liquid is easy to stick inside the tank and is difficult to be completely discharged. Utility Model Content

[0007] Furthermore: the main device includes an evaporator, a pressure reducer is installed in front of the evaporator, a heating source is installed on the outside of the evaporator, a discharge pipe is installed at the bottom of the evaporator, a one-way valve is installed on the top of the evaporator, an air guide pipe is arranged in the middle of the one-way valve, a heat exchange pipe is arranged in the middle of the air guide pipe, and a condenser is installed at the bottom of the air guide pipe.

[0008] Furthermore: the bottom of the evaporation tank is funnel-shaped.

[0009] Furthermore: the air guide pipe passes through the preheating tube, and the heat exchange tube is located inside the preheating tube.

[0010] Furthermore: the connecting pipe is connected to the evaporation tank flange.

[0011] Furthermore, the bracket is connected to the evaporator by bolts, and the rotating shaft is connected to the bracket bearing.

[0012] Furthermore: the guide rod and the rotating shaft are welded together.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When in use, the sewage to be treated is first sent into the preheating cylinder from the liquid inlet pipe, and then enters the bottom of the evaporator through the connecting pipe. The evaporator supports the pressure reducer to extract the air in the evaporator to reduce the internal air pressure, thereby lowering the boiling point of the sewage, making it easier to use less heat to complete the evaporation process, saving energy costs. During processing, the evaporator supports the heating source to heat the sewage in the evaporator, so that the water vapor passes through the one-way valve and enters the air guide pipe after boiling. During the movement of the water vapor along the air guide pipe, the water vapor at the heat exchange tube produces heat exchange with the sewage to be treated in the preheating cylinder, releasing heat in advance, and the sewage in the preheating cylinder is heated in advance, reducing the heat required for subsequent evaporation, further reducing the energy required for heating by the heating source, reducing the cost required for evaporation, and improving the economy of the device. The water vapor finally enters the condenser for condensation, completing sewage recovery;

[0015] The motor drives the rotating shaft to drive the guide rod to rotate. The guide rod scrapes the inner wall and bottom of the evaporator at the same time, so that the mucus flows along the guide groove on the guide rod, driving all the liquid to flow out along the discharge pipe. By arranging the guide rod on the rotating shaft, it is convenient to discharge all the residues and facilitate recycling. BRIEF DESCRIPTION OF THE DRAWINGS
