Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to an environmentally friendly water spray tower for preparation production. Background Art

[0002] As a pre-treatment device in waste gas treatment, the water spray tower plays a key role in many waste gas treatments, including dust removal and cooling. The water spray tower can change the sprayed liquid according to different purification needs. Due to the efficient adsorption effect of the spray tower, it is widely used in factories.

[0003] The wastewater after spraying in the traditional spray tower will be discharged directly, which consumes a huge amount of water and does not meet the energy conservation and emission reduction standards. In order to reduce the water consumption during use, the existing water spray tower usually recycles the spray water. When the water pump is used to circulate the spray water, since the spray water will be mixed with impurities after dust removal, the water pump is very likely to be damaged by impurities, which greatly affects the work progress and increases the maintenance and use costs. In addition, the temperature of the high-temperature exhaust gas transported in the spray tower is basically around 300 degrees. The spray water circulates for a long time and reacts with the exhaust gas, and the temperature of the spray water gradually increases, and the cooling effect will be greatly reduced. Therefore, the spray water needs to be replaced regularly, which is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a spray tower which can filter and cool spray water, thereby improving the use effect and working efficiency of the equipment.

[0005] The utility model is realized through the following technical scheme: an environmentally friendly water spray tower for preparation production, comprising a tower body, a spray chamber provided in the tower body, a spray assembly provided in the spray chamber, an air inlet provided on the side wall of the spray chamber, an air outlet provided on the top of the spray chamber, a water outlet provided at the bottom of the spray chamber, a filter connected to the water outlet, a cooling box provided on one side of the tower body, a first water pump connected between the water outlet of the filter and the water inlet of the cooling box, and a second water pump connected between the water outlet of the cooling box and the water inlet of the spray assembly.

[0006] In this solution, the spray water flows from the drain port through a filter to remove impurities and flows into the first water pump, thereby avoiding damage to the water pump by impurities and increasing the service life of the water pump. The water is then cooled in a cooling box and recycled, thereby ensuring the cooling effect on the exhaust gas and improving work efficiency.

[0007] As an optimization, a partition is fixedly connected in the tower body, the spray chamber is formed above the partition, the operation chamber is formed below the partition, and the filter is arranged in the operation chamber. This optimization scheme protects the filter.

[0008] As an optimization, an observation window is provided on the outer wall of the spray room, and a manhole is provided on the outer wall of the operating room. In this optimization scheme, the observation window is provided to facilitate observation of the dust removal status in the spray room, and the manhole is provided to facilitate personnel to maintain and repair the filter.

[0009] As an optimization, a quartz sand filter layer and an activated carbon filter layer are sequentially arranged in the filter from top to bottom. This optimization scheme improves the filtering effect of impurities in the spray water through multi-layer filtration.

[0010] As an optimization, the cooling box includes a box body, and a heat dissipation fan is arranged on the top of the box body. This optimization scheme cools the spray water by the heat dissipation fan.

[0011] As an optimization, a water collecting bucket is provided in the box below the heat dissipation fan, and the water inlet of the cooling box is provided above the water collecting bucket. In this optimization scheme, the incoming spray water is buffered by the water collecting bucket, and the spray water flows through the water collecting bucket and then falls, thereby accelerating the cooling speed.

[0012] As an optimization, a spiral guide plate is fixed on the inner wall of the water collecting bucket, and the guide plate extends downward along the circumference of the side wall of the water collecting bucket. This optimization solution further guides the spray water flowing through the guide plate, and the spray water flow path becomes longer, further improving the cooling speed.

[0013] As an optimization, the spray assembly includes a vertically arranged main pipe, and the outer wall of the main pipe is provided with multiple horizontal branches distributed along the circumference, and multiple spray nozzles are arranged on the horizontal branches. In this optimization scheme, the horizontal branches are distributed circumferentially to reduce the dead angle of spraying, so that the spray water can fully contact and react with the exhaust gas, and improve the dust removal and cooling effect.

[0014] As an optimization, the plurality of horizontal branches are distributed in multiple groups along the length direction of the main pipe. In this optimization scheme, multiple groups of horizontal branches are arranged from top to bottom, and spraying water is sprayed through more horizontal branches to further improve the dust removal and cooling effect.

[0015] The beneficial effects of the utility model are as follows: the spray water flows from the water outlet through the filter to remove impurities and flows into the first water pump, thereby preventing the impurities from damaging the water pump and increasing the service life of the water pump. The filter is provided with multiple filter layers to ensure the impurity removal and filtering effect.

[0016] After being cooled in the cooling box, it is recycled to ensure the cooling effect of the exhaust gas and improve work efficiency. In addition, the horizontal branch pipes of the spray assembly are distributed along the circumference and length of the main pipe to enhance the dust removal and cooling effect.
