Description

Technical Field

[0001] This utility model relates to the field of chemical and pharmaceutical production equipment technology, specifically a condenser for butyramide preparation. Background Technology

[0002] Butyramide is a chemical substance with the molecular formula C4H9NO. It is a colorless, leaf-shaped crystal with a melting point of 114.8℃ and a boiling point of 216℃. It is soluble in water. A condenser is a component of a refrigeration system and belongs to the category of heat exchangers. It can convert gas or vapor into liquid and transfer heat from the tubes to the air near the tubes in a rapid manner.

[0003] Patent document CN209322757U discloses a condenser for butyramide preparation, comprising a shell, a refrigerant tank, a water tank, a condensation chamber, a sodium ion exchange resin tank, an oxygen scavenger layer, a cold water pump, a spray chamber, an evaporation chamber, and a filter screen. The right inner wall of the shell is fixedly connected to the right outer wall of the condensation chamber, and the upper part of the condensation chamber on the right inner wall of the shell is fixedly connected to the right outer wall of the water tank. The left side of the water tank on the top of the base on the top outer wall of the condensation chamber is fixedly connected to the bottom of the refrigerant tank. This condenser for butyramide preparation employs a sodium ion exchange resin tank design, where sodium ions exchange calcium and magnesium ions in the cooling water to prevent scale formation when the cooling water flows over metal surfaces. The oxygen scavenger layer design removes dissolved oxygen in the cooling water, preventing metal corrosion. This equipment effectively prevents rust and scale formation, maintaining good heat exchange performance of the condenser.

[0004] Although the aforementioned patent achieves the function of preventing rust and scale in the equipment, thereby maintaining a good heat exchange effect of the condenser, it uses the method of dissolving cooling water with butyramide vapor and using an electric heating wire to heat and evaporate the cooling water into which the amide is dissolved to precipitate butyramide crystals. The efficiency of cooling and separating butyramide is low. In addition, the cooling water cannot be recycled after heating and evaporation. It is necessary to re-produce cooling water to remove oxygen and calcium and magnesium ions, which increases the production cost.

[0005] Therefore, we have made improvements to this and proposed a condenser for the preparation of butyramide. Utility Model Content

[0017] As a preferred embodiment, a mesh plate is provided at the connection between the coolant cylinder and the clean water tank, and a coolant pipe is connected to the upper side wall of the coolant cylinder, with valve B provided on the coolant pipe.

[0018] As a preferred embodiment, the upper part of the cooling box B is connected to an exhaust valve.

[0019] This utility model has the following beneficial effects:

[0020] The coolant for cooling the heat dissipation blades is drawn from the bottom of the outer tank into the cooling tank. After being cooled by the cooling tank B, it passes through the clean water tank and the coolant cylinder again before entering the cooling tank A, thus realizing the recycling of the coolant.

The water tank 10 and the coolant cylinder 11 are sealed by a water inlet switch. A cooling box A12 is connected to the bottom of the coolant cylinder 11. A water pump A13 is connected to the bottom of one side of the cooling box A12. A pipe of the water pump A13 is connected to an annular connecting plate 14. The annular connecting plate 14 is located in the upper part of the inner cavity of the outer tank 1. The outer wall of the inner ring of the annular connecting plate 14 is fixedly fitted with the outer wall of the air outlet pipe 4. A plurality of evenly distributed nozzles 15 are provided on the lower surface of the annular connecting plate 14. The heads of the nozzles 15 are facing the heat dissipation blades 5.

[0033] A cooling box B16 is fixedly installed on the upper outer wall of the outer tank 1. A water pump B17 is connected to the bottom of the cooling box B16. The water pump B17 is connected to the bottom pipe of the side wall of the outer tank 1.

[0034] The outer tank 1 is provided with a discharge pipe 18 at the bottom of its side wall. The discharge pipe 18 is connected to the bottom of the side wall of the cooling cylinder 2. The discharge pipe 18 located outside the outer tank 1 is provided with a valve A19.

[0037] The lower part of the side wall of the water tank 10 is provided with a material exchange pipe 23, and the material exchange pipe 23 is provided with a sealing cover 24.

[0038] A mesh plate is provided at the position where the coolant cylinder 11 is connected to the clean water tank 10, and a coolant pipe 25 is connected to the upper side wall of the coolant cylinder 11, and a valve B26 is provided on the coolant pipe 25.

[0039] The upper part of the cooling box B16 is connected to an exhaust valve 27.

[0040] The working principle of this utility model:

[0041] Sodium ion exchange resin is filled into the water tank 10 through the filling pipe 20. An oxygen remover is added to the water tank 10 through the reagent pipe 22. Clean water is injected into the water tank 10 through the water inlet pipe. After the sodium ion exchange resin and the oxygen remover have treated the clean water, the water inlet switch is opened, and valve B26 is opened at the same time. Coolant is introduced into the coolant pipe 25, and water pump A13 is turned on. The coolant, which consists of coolant and treated clean water, enters the cooling tank A12 and fills the inner cavity of the outer tank 1. The above steps are repeated several times until the coolant completely fills the inner cavity of the outer tank 1. Then water pump B17 is turned on to draw the coolant from the bottom of the outer tank 1 into the cooling tank B16. After being cooled by the cooling tank B16, the coolant passes through the water tank 10 and the coolant cylinder 11 again and enters the cooling tank A12, thereby realizing the recycling of the coolant.

[0042] At the same time, butyramide vapor is introduced into the feed pipe 6. The butyramide vapor enters the cooling cylinder 2 through the air inlet pipe 3. The heat dissipation blades 5 transfer the heat of the butyramide vapor to the coolant in the inner cavity of the outer tank 1. The cooled and liquefied butyramide is collected at the bottom of the cooling cylinder 2, which simplifies the cooling process and improves the cooling efficiency of butyramide.

[0043] The remaining gas is recirculated into the cooling cylinder 2 through the air outlet pipe 4 and the air inlet pipe 3. The air pressure valve 9 detects the air pressure in the cooling cylinder 2. When the air pressure in the cooling cylinder 2 reaches the preset air pressure, the solenoid valves A7 and B8 are closed. After standing for a period of time until the air pressure in the cooling cylinder 2 no longer changes, the air pressure valve 9 discharges the air pressure in the cooling cylinder 2, and the valve A19 is opened. The butyramide liquid in the cooling cylinder 2 is discharged through the discharge pipe 18.
