Description

Technical Field

[0001] This utility model relates to the field of sulfur trioxide gas condensation technology, specifically a sulfur trioxide gas condenser. Background Technology

[0002] Sulfur trioxide, also known as sulfuric anhydride, is an inorganic compound with the chemical formula SO3. Sulfur trioxide is a strong oxidizing agent that can oxidize sulfur, phosphorus, iron, zinc, bromides, iodides, and other substances at high temperatures. It is liquid at room temperature and pressure. In the production process of liquid sulfur trioxide, a condenser is needed to cool the sulfur trioxide gas into liquid sulfur trioxide.

[0003] The announcement number “CN206019383U” provides a new type of vertical sulfur trioxide gas condenser. The condenser has a vertical structure with a tube box at the bottom. Cooling water is sprayed into an independent water collection tank, and the water collection tank is not connected to the condenser, which simplifies the production process and saves costs.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Firstly, the heat exchange tubes in this condenser have a simple structure and poor heat exchange effect. Furthermore, there is no structure inside the shell to extend the path of sulfur trioxide gas, which means that the sulfur trioxide gas entering the shell cannot be adequately cooled. Secondly, the cooling water in the water collection tank of this condenser is also prone to heat accumulation after a period of use, which further reduces the heat exchange effect of the cooling water and makes it impractical. Utility Model Content

[0006] The purpose of this invention is to provide a sulfur trioxide gas condenser to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sulfur trioxide gas condenser includes a condensation chamber, a liquid outlet pipe, a water storage base, and a gas inlet pipe. The condensation chamber is fixedly connected to the upper surface of the water storage base. The liquid outlet pipe is fixedly connected to the lower side of the left end face of the condensation chamber, and the gas inlet pipe is fixedly connected to the upper side of the right end face of the condensation chamber. A cooling component is provided inside the condensation chamber to cool the sulfur trioxide gas entering the condensation chamber. An auxiliary heat dissipation component is provided inside the water storage base to cool the cooling water inside the water storage base.

[0009] Preferably, the cooling assembly includes a circulating pump, a water inlet pipe, a distribution shell, water guide vertical pipes, and a heat absorption sleeve. The circulating pump is installed on the lower right side of the water storage base. The distribution shell is fixedly connected to the upper inside of the condensation tank. A water inlet pipe is connected between the water inlet end of the distribution shell and the water outlet end of the circulating pump. Multiple water guide vertical pipes are fixedly connected to the lower end of the distribution shell. A heat absorption sleeve is fixedly connected to the annular side of the water guide vertical pipes.

[0010] Preferably, the heat-absorbing sleeve has multiple heat-absorbing fins fixedly connected to its annular side, and the heat-absorbing sleeve is filled with thermally conductive filler, which is made of diamond powder.

[0011] Preferably, the auxiliary heat dissipation component includes a connecting shell, an axial flow fan, and a heat absorption pipe. Multiple heat absorption pipes are fixedly connected to the lower side of the inside of the water storage base. The left end of the heat absorption pipe is fixedly connected to the connecting shell, and the left end of the connecting shell is equipped with an axial flow fan.

[0012] Preferably, ventilation cavities are symmetrically provided on the left and right end faces and the front and rear end faces of the water storage base, and dustproof mesh plates are installed on the outer walls of the ventilation cavities, and the dustproof mesh plates are detachable.

[0013] Preferably, the condenser box has multiple baffles fixedly connected inside, and the baffles are arranged in an alternating manner.

[0014] Preferably, a water supply valve is installed on the upper side of the left end face of the water storage base, and a drain valve is installed on the lower side of the left end face of the water storage base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using a circulating pump to deliver cooling water from inside the water storage base through the inlet pipe and the distribution shell to multiple water guide vertical pipes, the cooling water can cool the water guide vertical pipes. This allows the water guide vertical pipes to absorb heat and cool the sulfur trioxide gas entering the condenser through the heat-conducting packing, heat-absorbing sleeves, and heat-absorbing fins. At the same time, the multiple staggered baffles can extend the path of the sulfur trioxide gas inside the condenser, allowing the multiple heat-absorbing sleeves and heat-absorbing fins to fully cool the sulfur trioxide gas, thereby cooling the sulfur trioxide gas inside the condenser into liquid sulfur trioxide.

[0017] 2. By starting the axial flow fan, the fan can blow air through the connecting shell to the inside of multiple heat absorption tubes to cool them down. This allows the multiple heat absorption tubes to absorb most of the heat from the cooling water inside the water storage base. At the same time, some outside air will enter the water storage base through the dustproof mesh and ventilation cavity for ventilation and heat dissipation, thus preventing the cooling water inside the water storage base from easily accumulating heat. This makes it highly practical. Attached Figure Description

[0026] Example 1:

[0027] A sulfur trioxide gas condenser includes a condensation tank 1, a liquid outlet pipe 2, a water storage base 3, and a gas inlet pipe 6. The condensation tank 1 is fixedly connected to the upper end face of the water storage base 3. The condensation tank 1, water storage base 3, liquid outlet pipe 2, and gas inlet pipe 6 are all made of rust-resistant aluminum alloy. The rust-resistant aluminum alloy material provides good corrosion resistance, preventing easy corrosion by sulfur trioxide. The liquid outlet pipe 2 is fixedly connected to the lower left end face of the condensation tank 1. The outlet is connected to the inlet of an external liquid sulfur trioxide storage tank. The liquid outlet pipe 2 can introduce the cooled, liquid sulfur trioxide inside the condenser 1 into the external liquid sulfur trioxide storage tank. A gas inlet pipe 6 is fixedly connected to the upper side of the right end face of the condenser 1. The inlet of the gas inlet pipe 6 is connected to the sulfur trioxide gas outlet. The gas inlet pipe 6 can introduce sulfur trioxide gas into the condenser 1 for cooling. The gas inlet pipe 6 and the liquid outlet pipe 2 are integrated with the condenser 1. A liquid level observation window is provided on the upper side of the front end face of the water storage base 3. Figure 1 (Already drawn) The liquid level observation window allows staff to easily observe the cooling water level inside the water storage base 3.

[0028] A water supply valve 31 is installed on the upper side of the left end face of the water storage base 3. The inlet of the water supply valve 31 is connected to the outlet of the external cooling water storage tank through a pipe. The water supply valve 31 facilitates the replenishment of cooling water into the water storage base 3 by the staff. A drain valve 32 is installed on the lower side of the left end face of the water storage base 3. The outlet of the drain valve 32 is connected to the inlet of the external wastewater treatment pool through a pipe. The drain valve 32 facilitates the drainage of the cooling water inside the water storage base 3 for replacement by the staff. A cooling component 5 is installed inside the condenser box 1. The cooling component 5 is used to cool down the sulfur trioxide gas entering the condenser box 1, so that the sulfur trioxide gas is cooled into liquid sulfur trioxide. An auxiliary heat dissipation component 4 is installed inside the water storage base 3. The auxiliary heat dissipation component 4 is used to cool down the cooling water inside the water storage base 3 to prevent heat accumulation in the cooling water inside the water storage base 3.

[0029] Cooling assembly 5 includes a circulating pump 51, an inlet pipe 52, a distribution shell 53, a water guide riser 54, and a heat absorption sleeve 56. The circulating pump 51 is installed on the lower right side of the water storage base 3. The circulating pump 51 is connected to an external control panel via wires. During operation, the circulating pump 51 delivers cooling water from inside the water storage base 3 to the inlet pipe 52. A distribution shell 53 is fixedly connected to the upper inside of the condenser 1. The distribution shell 53 is welded to both the inlet pipe 52 and the water guide riser 54. The distribution shell 53 can divert cooling water to… Among the multiple water guide risers 54, an inlet pipe 52 is connected between the water inlet end of the distribution shell 53 and the water outlet end of the circulating pump 51. The inlet pipe 52 is connected to the condenser box 1 by welding. The inlet pipe 52 can guide cooling water into the distribution shell 53. Multiple water guide risers 54 are fixedly connected to the lower end face of the distribution shell 53. The water guide risers 54 are connected to the condenser box 1 by welding. The multiple water guide risers 54 not only facilitate the flow of cooling water through the interior of the condenser box 1, but also facilitate the absorption of heat transferred from the heat-conducting filler 57 by the cooling water.

[0030] A heat-absorbing sleeve 56 is fixedly connected to the annular side of the water-guiding riser 54. The heat-absorbing sleeve 56 is connected to the water-guiding riser 54 and the heat-absorbing fins 55 by welding. The heat-absorbing sleeve 56 can absorb heat and cool the sulfur trioxide gas inside the condenser box 1. Multiple heat-absorbing fins 55 are fixedly connected to the annular side of the heat-absorbing sleeve 56. The multiple heat-absorbing fins 55 can further increase the heat absorption area of ​​the heat-absorbing sleeve 56. The heat-absorbing sleeve 56 is filled with thermally conductive filler 57, and the thermally conductive filler 57 is made of diamond powder. The thermally conductive filler 57 made of diamond powder has a good thermal diffusivity so that the heat absorbed by the heat-absorbing sleeve 56 can be transferred to the water-guiding riser 54. Multiple baffles 58 are fixedly connected inside the condenser box 1. The multiple baffles 58 are arranged in an alternating manner. The multiple baffles 58 arranged in an alternating manner can extend the path of the sulfur trioxide gas inside the condenser box 1 so that the multiple heat-absorbing sleeves 56 can fully cool the sulfur trioxide gas.

The inlet pipe 52, the diversion shell 53, the water guide riser 54, the heat-absorbing fins 55, the heat-absorbing sleeve 56, and the baffle plate 58, all made of rust-resistant aluminum alloy, not only have good corrosion resistance and avoid being easily corroded by sulfur trioxide, but also have good thermal conductivity.

[0032] Example 2:

[0033] Based on Embodiment 1, in this embodiment, by starting the axial flow fan 42, the axial flow fan 42 can blow air into the interior of multiple heat absorption pipes 43 through the connecting shell 41 to cool down the water. This allows the multiple heat absorption pipes 43 to absorb most of the heat from the cooling water inside the water storage base 3. At the same time, some external air will enter the interior of the water storage base 3 through the dustproof mesh plate 45 and the ventilation cavity 44 for ventilation and heat dissipation, thereby preventing the cooling water inside the water storage base 3 from easily accumulating heat.

[0034] The auxiliary heat dissipation component 4 includes a connecting shell 41, an axial flow fan 42, and heat absorption pipes 43. Multiple heat absorption pipes 43 are fixedly connected to the lower side of the water storage base 3. The heat absorption pipes 43 are connected to the water storage base 3 and the connecting shell 41 by welding. The multiple heat absorption pipes 43 can absorb heat from the cooling water inside the water storage base 3. The connecting shell 41 is fixedly connected to the left end of each heat absorption pipe 43. The connecting shell 41 can distribute the air blown by the axial flow fan 42 to the multiple heat absorption pipes 43. The axial flow fan 42 is installed on the left end of the connecting shell 41 and is controlled externally via wires. The panels are connected, and the axial flow fan 42 can blow air into the connecting shell 41 when it is working. The left and right end faces and the front and rear end faces of the water storage base 3 are symmetrically provided with ventilation chambers 44. The ventilation chambers 44 facilitate the entry of external air into the water storage base 3 for ventilation and cooling. The outer wall of the ventilation chamber 44 is equipped with a dustproof mesh plate 45. The dustproof mesh plate 45 can filter and remove dust from the passing air, preventing most of the dust in the external air from directly entering the water storage base 3. The dustproof mesh plate 45 is a detachable structure, which makes it convenient for staff to replace or clean it later.

[0035] Working principle: First, the operator opens the water supply valve 31 to add an appropriate amount of cooling water to the water storage base 3. During this process, the cooling water level must not exceed the height of the water supply valve 31. Then, the circulation pump 51 is started, which transports the cooling water inside the water storage base 3 through the inlet pipe 52 to the distribution shell 53. At this time, the distribution shell 53 will divert the cooling water to multiple water guide risers 54 for cooling. Subsequently, the cooling water will flow back into the water storage base 3 through the water guide risers 54 for recycling. Simultaneously, the gas inlet pipe 6 introduces sulfur trioxide gas into the condenser 1. At this time, multiple heat-absorbing sleeves 56 and heat-absorbing fins 55 absorb heat and cool the passing sulfur trioxide gas. The heat-conducting filler 57 transfers most of the heat absorbed by the heat-absorbing sleeves 56 to the water guide risers 54, so that the cooling water flowing through the water guide risers 54 absorbs and cools the transferred heat. This also facilitates heat exchange. The staggered arrangement of multiple baffles 58 extends the path of sulfur trioxide gas inside the condenser box 1, allowing multiple heat-absorbing tubes 56 to fully cool the sulfur trioxide gas, thereby cooling the sulfur trioxide gas inside the condenser box 1 into liquid sulfur trioxide. The cooled liquid sulfur trioxide flows downward and is discharged through the liquid outlet pipe 2. When the operator starts the axial flow fan 42, the working axial flow fan 42 blows air into the multiple heat-absorbing tubes 43 through the connecting shell 41 to ventilate and cool the multiple heat-absorbing tubes 43. The cooled multiple heat-absorbing tubes 43 absorb most of the heat of the cooling water inside the water storage base 3. At the same time, some external air enters the water storage base 3 through the dustproof mesh plate 45 and the ventilation cavity 44 for ventilation and heat dissipation, thereby preventing the cooling water inside the water storage base 3 from easily accumulating heat, thus ensuring the cooling effect of the cooling water inside the water storage base 3.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
