Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically, to chemical condensation equipment for preventing scale residue. Background Art

[0002] Chemical raw materials can be divided into organic chemical raw materials and inorganic chemical raw materials. Organic chemical raw materials can be divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and their derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylates, carbohydrates, etc.

[0003] After searching, the existing patent (publication number: CN214792045U) discloses a chemical condensation equipment with a circulating condensation effect, which belongs to the field of chemical production technology, and includes a placement box, and a cold water channel is opened on the lower surface of the placement box, and the right side of the cold water channel is connected to the left end of the connecting pipe. The chemical condensation equipment with a circulating condensation effect directly controls the operation of the water pump, the cooling box and the fan assembly by setting a cold water channel, a water pump, a return pipe, a cooling box and a fan assembly. The water pump controls the water flow in the water tank to enter the return pipe through the cold water channel. The upper side of the return pipe is open, and the water flow in the return pipe can automatically absorb the heat inside the placement box and dissipate heat while flowing downstream. At the same time, the fan assembly can speed up the air flow speed around the placement box and the return pipe, so that the rising and falling processes of the water flow can both dissipate heat and cool down. At the same time, it can reduce the energy consumption of the cooling box when cooling the water flow, so that the efficiency and practicality of the device are relatively ideal. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] In existing condensing equipment, the fluid temperature inside the condenser tube is relatively low. When water vapor in the external air contacts the surface of the condenser tube, the surface temperature of the condenser tube is lower than the air temperature, causing the water vapor to condense into water droplets and form condensation. This condensation will cause water accumulation and increase the risk of corrosion of the pipe. In addition, scale is formed by the precipitation of calcium and magnesium minerals in the water. Over time, these precipitates will accumulate inside the pipe, causing a reduction in water flow and affecting the service life of the equipment.

[0005] Therefore, in order to solve the above problems, a chemical condensation equipment for preventing scale residue is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] As attached Figures 1 to 4 A chemical condensation device for preventing scale residue is shown, comprising a base 1, an outer shell 2, an inner shell 3 and a mixing box 7, wherein the outer shell 2 is arranged on the upper end surface of the base 1, the inner shell 3 is arranged in the inner cavity of the outer shell 2, an interlayer 4 is provided between the outer shell 2 and the inner shell 3, and a condensation pipe 14 is installed on the outer surface of the inner shell 3, a cooling box 16 is arranged on the left side of the outer shell 2, a second water pump 18 is arranged on the left side of the cooling box 16, and a water supply box 19 is arranged on the left side of the second water pump 18;

[0025] The mixing box 7 is arranged on the right side of the base 1, and a feed port 9 is opened at the upper end of the right side of the mixing box 7, and a driving motor 8 is arranged below the feed port 9. A transmission shaft 10 is arranged in the inner cavity of the mixing box 7, and a stirring blade 11 is arranged on the outer surface of the transmission shaft 10. A suction pipe 13 is arranged on the left side of the transmission shaft 10, and a first water pump 12 is arranged at the upper end of the mixing box 7, and a feed pipe 121 is arranged at the output end of the first water pump 12.

[0026] Among them: when the condensing equipment is running, the second water pump 18 pumps water from the water supply tank 19 into the cooling box 16, and then the cooling box 16 sends the condensed water into the condensing pipe 14 through the connecting pipe 17 to condense the inner shell 3. The three-layer insulation mechanism formed by the outer shell 2, the inner shell 3 and the interlayer 4 can effectively prevent the conduction of heat, ensure that the temperature change of the external environment will not quickly affect the temperature of the inner layer, thereby keeping the temperature of the inner layer relatively stable, and the temperature difference in the condensing pipe 14 area is reduced, thereby avoiding the condensing medium from being affected by the external environment temperature. The possibility of condensation is reduced. When scale needs to be cleaned, the descaling agent and water are mixed in proportion and poured into the inner cavity of the mixing box 7. The drive shaft 10 is driven to rotate by the driving motor 8, so that the stirring blade 11 mixes the descaling agent. After mixing, it enters the feed pipe 121 through the output end of the first water pump 12, and is connected to the condenser 14 to enter the pipe body for descaling. The descaling agent reacts chemically with scale components such as calcium and magnesium to form soluble substances, thereby effectively removing the scale attached to the inner wall of the condenser 14, and the scale is discharged through the drain pipe 15 as the water source flows.

The insulation cotton in the interlayer 4 can prevent the temperature difference between the outer shell 2 and the inner shell 3 from affecting the condenser 14, and the outer shell 2 and the inner shell 3 also provide two layers of insulation effect, thereby preventing the occurrence of condensation inside the equipment, reducing the risk of corrosion, extending the life of the equipment and reducing energy loss.
