Description

Independent modular carbon dioxide removal cooler {APPARATUS FOR REMOVING CARBON DIOXIDE IN AN INDEPENDENT MODULE}

The present invention relates to an independent modular carbon dioxide removal cooler, and more specifically, to increase the transfer efficiency of coolant and improve the convenience of maintenance, a shell in which a tube through which coolant moves is arranged is configured in the form of an independent module, and the shell This relates to an independent modular carbon dioxide removal cooler that can be stacked in multiple stages.

As is known, a condenser condenses and liquefies the high-temperature and high-pressure gas produced by the compressor. Since the high-temperature and high-pressure gas produced by the compressor has a temperature higher than room temperature (70 to 110°C), it releases heat to the surroundings over time. It gradually condenses. However, in the case of a refrigerator that operates continuously, the condensation rate must be accelerated as much as possible.

The simplest way to increase the condensation rate is to increase the heat transfer area by making the condenser itself larger, but since this has limitations in actual space, a structure that allows good heat transfer even in a small area is needed.

For this purpose, the previously proposed technology includes a method of arranging multiple pins to expand the heat transfer area, and arranging a rotating fan so that the gas molecules that gain heat do not stay but escape to the outside, leaving the cold. There is a method of increasing the temperature difference by continuously supplying gas molecules. Equipment that condenses by forcing air to circulate in this way is called an air-cooled condenser.

Another method is a water-cooled condenser. These water-cooled condensers are classified into parallel flow, in which the high-temperature fluid and low-temperature fluid flow in the same direction, and counter-flow, in which the high-temperature fluid and low-temperature fluid flow in opposite directions. In the case of counterflow, the high-temperature side The outlet temperature of the fluid can be lower than the outlet temperature of the low-temperature fluid, which has the advantage of excellent heat transfer ability.

For example, in a shell-and-tube condenser, a high-temperature refrigerant and coolant exchange heat, and when the coolant gains heat and becomes high temperature, its heat transfer performance deteriorates when it moves to the condenser, so it enters the cooling tower and evaporates, becoming low-temperature.

In order to increase the efficiency of heat exchange in such water-cooled condensers, it is desirable to expand the area where the moving gas and coolant come into contact or increase the residence time of the gas. To achieve this, the length of the tube through which the coolant moves must be extended, which requires shell and As the length or diameter of the column in which the tube is placed increases, there are problems such as restrictions on the installation location and increased installation costs.

In addition, as the length of the column increases, it becomes more difficult to maintain the internal components, it is difficult to accurately calculate the heat transfer efficiency of the coolant, and in particular, it is impossible to increase or decrease the heat transfer efficiency of the coolant during use, which is a problem of low utilization. There was this.

On the other hand, there is an evaporative condenser. The evaporative condenser is a concept that combines a water-cooled condenser and a cooling tower. It directly uses the latent heat when the water evaporates by spraying cooling water directly into the condenser. This evaporative condenser requires a separate cooling tower. It has the advantage of saving space and having a low condensation temperature.

The present invention was proposed to solve the above problems, and the shell with the tube disposed inside is configured in the form of an independent module to increase the heat transfer efficiency of the coolant, and the shell is configured to be stacked in multiple stages to achieve the required heat transfer. The purpose is to provide an independent modular carbon dioxide removal cooler that can be configured in the required number in response to efficiency, thereby increasing utilization.

In addition, the purpose of the present invention is to provide an independent modular carbon dioxide removal cooler that is made in the form of an independent module and improves the convenience of maintenance, such as replacing only the shell in which a problem occurs.

In addition, the present invention increases the separation efficiency of gas and liquid by arranging the gas outlet through which the moisture-removed gas is discharged and the condensate outlet through which the moisture separated from the gas is discharged at vertically spaced positions, and reduces the overall size of the column. The purpose is to provide a stand-alone modular carbon dioxide removal cooler that can reduce carbon dioxide emissions.

In addition, the tube is disposed along the upper and lower heights of the passage and is bent in a spiral shape a number of times.

In addition, the shell is characterized in that a plurality of shells are arranged so that they can be stacked in the vertical direction.

At this time, when a plurality of the shells are stacked in the vertical direction, the coolant moves from the shell located relatively below to the shell located relatively above.

In addition, the condensate storage tank has an upper end where the cells are combined and a gas outlet through which the moisture-removed gas is discharged at the upper part, and has a relatively narrow width compared to the upper end and can discharge condensate separated from the gas at the lower part. It is characterized by including a bottom provided with a condensate outlet.

The present invention achieved as described above can be expected to have the effect of increasing the separation efficiency of moisture contained in the gas by increasing the heat transfer efficiency of the coolant.

In addition, the present invention has the effect of easily responding to design changes because the shell with the tube disposed inside is formed in the form of an independent module, so that the number of layers to be stacked can be adjusted according to the required heat transfer efficiency.

In addition, since the present invention is constructed by stacking a plurality of unit shells in the form of independent modules, it has the effect of improving the convenience of maintenance, such as replacing or repairing a defective unit shell among each unit shell.

Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the technical field to which the present invention pertains.

No.

Hereinafter, a preferred embodiment of the independent modular carbon dioxide removal cooler according to the present invention will be described with reference to the attached drawings.

First, as shown in FIG. 1, the independent modular carbon dioxide removal cooler 1 according to the present invention is formed with a passage 11 through which a gas containing moisture moves, and an inlet through which cooling water is introduced on one side. 12), and a shell 10 provided with an outlet 13 through which coolant is discharged, disposed in the passage 11, one end of which communicates with the inlet 12, and the other end of which communicates with the outlet 13. A tube 20 is disposed and bent a number of times to increase the cross-sectional area of contact with the gas moving through the passage 11, and a condensate storage tank in which condensate separated from the gas passing through the passage 11 is stored. Includes (30).

The shell 10 is made in the form of a box with a passage 11 through which gas containing moisture moves, and the inlet 12 through which the coolant enters and the outlet 13 through which the coolant is discharged are spaced apart from each other. A plurality of pieces are stacked in the vertical direction according to the required heat transfer efficiency.

The passage 11 is a movement path through which moisture-containing gas moves and is also an arrangement space where a tube 20, which will be described later, is placed.

This passage 11 can be changed depending on the diameter of the shell 10 and the size of the arranged tube 20, and is of course not limited to the ratio shown in the drawing.

The inlet 12 and outlet 13 are through which coolant is introduced or discharged, respectively. In a state in which a plurality of shells 10 are stacked, the outlet 13 or inlet 12 of other shells 10 arranged adjacently is used. communicates with

Here, in a state in which a plurality of shells 10 are stacked, the outlet 13 provided in the uppermost shell 10 may be further provided with a safety valve 14 for controlling the discharge of coolant.

Meanwhile, the number of stacked shells 10 is the amount of moisture condensation required after calculating the expected amount of moisture condensation in the moisture-containing gas passing through the passage 11 that can be obtained through each unit shell 10. Stack the required number according to the number.

At this time, in addition to the expected amount of moisture condensation, the number of stacks can be adjusted by considering the temperature conditions of the inlet where the moisture-containing gas is introduced, the flow rate and speed of the moving gas, etc.

The number of shells 10 stacked, the diameter of the shell itself, the height, etc. can be selected and stacked at least two in consideration of the above-mentioned conditions. In particular, the shell 10 according to the present invention is configured as an independent module. Since the expected amount of moisture condensation that can be handled by each shell can be specified, the moisture condensation amount and heat exchange rate required for the column can be provided during the design process of manufacturing the column.

This has the advantage of being able to manufacture a column at a relatively low cost and shortening the manufacturing time compared to designing and manufacturing a new column depending on the amount of moisture condensation and heat exchange rate during the manufacturing process of a conventional column. there is.

The tube 20 is disposed in the passage 11 formed inside the shell 10, so that the coolant moves inside and comes into contact with the gas flowing through the passage 11 to exchange heat with the gas, and the inside is empty. It is made of a tubular body, and one end communicates with the inlet (12) and the other end communicates with the outlet (13).

In order to maximize the contact area with the gas in the same area, it is bent multiple times, and is preferably bent in a spiral shape to expand the contact area with the gas without restricting the movement of the coolant.

At this time, the diameter of the tube 20, the number of bends, and the diameter of the inner and outer circumferences when formed in a spiral shape are determined by the capacity and moving speed of the moving coolant, the area of the passage 11, and the contact with the moving gas. It can be changed considering the area, and of course, it is not limited to the form shown in the drawing.

The shell 10 formed as above and the tube 20 disposed in the shell 10 form one independent module, and the heat transfer efficiency of the coolant is calculated, and the required number of independent modules are stacked in the vertical direction, respectively. The inlet 12 and outlet 13 arranged in the shell 10 are connected to the outlet 13 and inlet 12 of another adjacent shell.

Afterwards, the moisture-containing gas delivered from above moves downward, and the coolant drawn from the inlet 12 of the shell 10 placed at the bottom of the stacked shells 10 moves downward as it moves through the tube. Heat exchange takes place in contact with the

This heat exchange takes place continuously through the stacked shell and the tube disposed inside the shell, and the moisture separated from the gas falls downward and is collected in the condensate storage tank 30, and the gas from which the moisture is separated is stored in the condensate storage tank. It is discharged through the gas outlet 311 provided above (30).

As described above, the shell is configured in the form of an independent module and a column is formed to separate gas and moisture by stacking multiple shells according to the heat transfer efficiency, so it is easy to respond to the required heat transfer efficiency and prevents operation errors among the stacked multi-stage shells. The convenience of maintenance, such as replacement and repair of damaged shells, has been improved.

The condensate storage tank 30 stores moisture separated from the gas, that is, condensate, and discharges the gas from which the moisture is separated. It includes a lower end (32) provided with a condensate discharge port (321).

The upper part 31 is joined to the lower part of the shell 10 disposed at the bottom of the stacked shells 10, and is formed to have a cross-section that gradually narrows downward so that the condensate separated from the gas moves downward. The condensate separated from the gas is guided to move downward along the slope.

In addition, the upper end 31 is provided with a gas outlet 311 through which the moisture-separated gas is discharged to the outside, thereby discharging the moisture-separated gas.

The lower end 32 extends downward from the bottom of the upper end 31 to store condensate separated from the gas, and is provided with a condensate outlet 321 for discharging the stored condensate.

Here, the condensate water outlet 321 is formed at a height difference from the gas outlet 311, so that the size of the condensate storage tank 30 can be reduced while securing a space for storing condensate, and also the gas outlet 311 can be stored at the top 31. An outlet 311 is provided so that the condensate stored at the bottom 32 is not mixed or affected, thereby increasing the separation efficiency of gas and condensate.

In the condensate storage tank 30 constructed as described above, the gas outlet 311 and the condensate outlet 321 are formed with a height difference from each other, thereby increasing the separation efficiency of gas and condensate, and in particular, the relative size compared to the outer diameter of the shell 10. It is formed to have a small outer diameter, which can reduce the overall size of the condenser, minimizing the installation area and environmental impact.
