Description

Technical Field

[0001] The utility model relates to the technical field of ammonium sulfate wastewater treatment, in particular to an ammonium sulfate wastewater evaporation heater. Background Art

[0002] Ammonium sulfate wastewater refers to wastewater containing ammonium sulfate ((NH4)2SO4) generated during the production process. If discharged directly without proper treatment, it can have negative impacts on the environment and ecosystems. Ammonium sulfate wastewater is primarily generated by industrial production and agricultural activities. In industrial production, ammonium sulfate is often used as a catalyst, stabilizer, or reactant, and thus, wastewater containing ammonium sulfate may be generated during the production process.

[0003] In the process of treating ammonium sulfate wastewater, it is necessary to heat and evaporate the ammonium sulfate wastewater to evaporate the water therein and form a wastewater concentrate, which can facilitate the subsequent purification of the ammonium sulfate wastewater. However, the existing ammonium sulfate evaporation heating equipment generally directly puts the ammonium sulfate wastewater into a heating container for direct heating and evaporation, and the evaporation efficiency is low.

[0004] The Chinese utility model patent with patent application number CN202322686540.7 records an ammonium sulfate wastewater evaporation and crystallization device, which is equipped with a fixed cylinder. After the wastewater enters the fixed cylinder, it drives the fan blades to rotate, the fan blades drive the rotating shaft to rotate, the rotating shaft drives the liquid separator to rotate, and the liquid separator drives the wastewater to rotate, so that the wastewater is evenly attached to the fixed cylinder along the liquid separator under the action of centrifugation, which is conducive to the device evenly attaching the wastewater to the fixed cylinder, so that the device can evenly and fully heat the wastewater and improve the evaporation and crystallization effect of the device. However, in the above-mentioned device, the fan blades are driven to rotate only by the power of the natural flow of wastewater, which will make the rotation speed of the fan blades, the rotating shaft and the liquid separator low. In this way, the wastewater cannot be fully attached to the inner wall of the fixed cylinder, resulting in low efficiency of the evaporation process. Utility Model Content

[0005] The purpose of the utility model is to provide an ammonium sulfate wastewater evaporation heater to solve the problem that the existing evaporation heating equipment proposed in the above background technology only drives the fan blades to rotate by the power of the natural flow of wastewater, which will cause the rotation speed of the fan blades, the rotating shaft and the liquid separator to be low, so that the wastewater cannot be fully attached to the inner wall of the fixed cylinder, resulting in low efficiency of the evaporation process.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an ammonium sulfate wastewater evaporation heater, comprising an evaporation box, a liquid inlet pipe connected to the top of the evaporation box, a partition fixedly connected between the inner walls of the evaporation box, a first auxiliary heating component provided on the partition, the first auxiliary heating component comprising a plurality of through holes opened on the top of the partition, a hollow tube fixedly connected to the inner walls of the plurality of through holes, a threaded heating tube fixedly wrapped around the outer circumference of the hollow tube, a water absorption layer provided in the hollow tube, the water absorption layer being cylindrical and its outer surface being in conflict with the inner wall of the hollow tube.

The advantage of such a setting is that the wastewater on the top of the water absorption layer can flow to the bottom of the water absorption layer through the overflow holes, thereby preventing the wastewater from being blocked above the water absorption layer and ensuring the smooth progress of the evaporation and heating work.

[0008] Preferably, the first auxiliary heating component also includes a fixing ring fixedly connected to the inner wall of the hollow tube, the fixing ring is located directly below the water absorption layer, and a plurality of first water guide rods are fixedly connected to the top of the fixing ring, the number of the plurality of first water guide rods is equal to the number of overflow holes on the fixed plate, and the plurality of first water guide rods are respectively located directly below the plurality of overflow holes, and a plurality of second water guide rods are fixedly connected to the outer peripheral surface of the first water guide rod, and the ends of the plurality of second water guide rods away from the first water guide rods are in contact with the inner wall of the hollow tube. The advantage of such a setting is that, in conjunction with the overflow hole, the wastewater flowing out of the overflow hole can be divided into multiple streams and respectively guided to various positions on the inner wall of the hollow tube, ensuring that the wastewater can be more evenly and fully attached to the inner wall of the hollow tube, so that the wastewater can be fully heated, thereby effectively improving the efficiency of the heating evaporation process.

[0009] Preferably, both the first water guide rod and the second water guide rod can be electrically heated. The advantage of such an arrangement is that the efficiency of heating and evaporating wastewater can be further improved.

[0010] Preferably, the top end of the first water guide rod is conical and extends to the inside of the overflow hole. The advantage of this arrangement is that the wastewater flowing from the overflow hole can be evenly dispersed to the outer peripheral surface of the first water guide rod, thereby ensuring that the wastewater can flow evenly to the outer peripheral surfaces of multiple second water guide rods, greatly improving the efficiency of heating and evaporating the wastewater.

[0011] Preferably, it also includes a second auxiliary heating assembly, which includes a first ring plate and a second ring plate fixedly connected to the top of the partition, the first ring plate is located in the center of the second ring plate, the outer peripheral surfaces of the first ring plate and the second ring plate are both annularly provided with multiple water outlet holes, the height of the first ring plate is higher than the height of the second ring plate, a first electric heating rod is fixedly connected to the center of the top of the partition, and a plurality of second electric heating rods are fixedly connected to the outer peripheral surface of the first electric heating rod in a ring shape, the second auxiliary heating assembly also includes a plurality of third electric heating rods fixedly connected to the outer peripheral surface of the first ring plate in a ring shape, and the bottom end of the liquid inlet pipe is located directly above the inner circle area of the first ring plate. The advantage of this arrangement is that the wastewater can be preheated before it flows into the hollow tube, thereby maximizing the efficiency of evaporation and heating of the wastewater.
