Description

Novel coil cooler

Technical Field

The utility model belongs to the technical field of the heat exchanger technique and specifically relates to a novel coil pipe cooler is related to.

Background

In the food and pharmaceutical industry, there are many concentration devices that use the characteristic of low boiling point of water or alcohol in vacuum as a cooling medium to achieve the purpose of energy saving, especially those equipped with a first-stage tubular condenser, a coil cooler and a water collector. The vacuum pumping has the function of reducing the boiling point of the medium, but the requirement for the equipment is correspondingly increased, wherein, the pressure balance in the equipment is difficult, the technical difficulty of the utility model is to maintain the pressure balance of the A area (figure 2) and the B area (figure 2). The pressure imbalance between the area a and the area B causes the following problems:

1. the medium flow speed in the coil of the coil cooler is accelerated, and the heat exchange efficiency is reduced.

2. The liquid entering the B area through the cooler is foamed after being intensively impacted, so that the problem of material leakage from the vacuumizing port is caused.

3. The long-term pressure imbalance causes damage to the equipment, shortens the service cycle of the equipment and increases the investment cost.

Disclosure of Invention

In order to overcome the shortcoming that above-mentioned prior art exists, the utility model provides a novel coil pipe cooler suitable for be equipped with one-level tubulation condenser, coil pipe cooler and receive the concentrator of hydrophone has the effect of maintaining the internal energy pressure balance of equipment and improve equipment heat exchange efficiency.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a novel coil pipe cooler, includes cooler barrel, cooler coil pipe and reinforced pipe, and the cooler coil pipe is located the cooler barrel, is equipped with cooling water inlet and cooling water outlet on the cooler barrel, its characterized in that: the cooler coil is arranged on an upper tube plate and a lower tube plate in the cooler barrel, a reinforcing tube penetrating through an upper cavity and a lower cavity is arranged at the center of the upper tube plate and the lower tube plate, the reinforcing tube is welded on a reinforcing rib of the upper tube plate and the lower tube plate, the reinforcing tube is penetrated through the upper cavity and the lower cavity connected with the cooler, the reinforcing tube reinforces the strength of the equipment, increases the vacuum flux of the equipment, and maintains the pressure balance of an area A and an area B; the technical scheme is further explained as follows: the upper end of the reinforcing pipe is welded with the reinforcing rib of the upper pipe plate, and the pipe orifice of the reinforcing pipe is 3-5 mm higher than the reinforcing rib; the pipe orifice at the lower end of the reinforced pipe is flush with the lower pipe plate reinforcing rib and welded to reduce liquid inflow; the technical scheme is further explained as follows: and the reinforcing ribs of the upper tube plate are provided with through flow holes to ensure the liquid circulation.

Detailed Description

The structure principle of the present invention will be further explained with reference to the accompanying drawings.

The structure and the application of the novel coil cooler are schematically shown in the figure, and the novel coil cooler comprises an equipment flange 1, a reinforcing pipe 2, a cooler barrel 3, a cooler coil 4, a pipe plate 5, a reinforcing rib 6, a cooling water inlet 7, a cooling water outlet 8, a through flow hole 9, a coil cooler 10, a primary tube-in-tube condenser 11 and a water collector 12.

The novel coil cooler is applied to concentration equipment provided with a primary tube array condenser, a coil cooler and a water collector, in order to maintain the balance of internal energy pressure of the equipment, improve the heat exchange efficiency of the equipment and prevent material foaming, the structure of the coil cooler is technically improved, a reinforcing tube penetrating through an upper cavity and a lower cavity is inserted into the center of an upper tube plate and a lower tube plate of the cooler and is welded with reinforcing ribs of the upper tube plate and the lower tube plate, and a joint above the reinforcing tube is welded with the reinforcing ribs and is 3-5 mm higher than the reinforcing ribs so as to reduce liquid inflow; the lower joint is flush with the reinforcing rib and welded. The holes are formed in the reinforcing ribs at the upper end of the cooler, so that the liquid circulation is ensured.

When the equipment normally works, the pressure difference between the area B and the outside atmosphere is the largest, the pressure difference is transmitted to the area A through the cooler coil pipe and the reinforcing pipe, so that liquid and non-condensed gas passing through the first-stage tubular condenser enter the area A, and the pressure difference between the area A and the outside atmosphere is smaller than (equal to) the pressure difference between the area B and the outside atmosphere; addition of reinforcing tubes

The strong effect can reduce the damage of the pressure difference to the equipment. The reinforced pipe can increase the flux of vacuum, and the reinforced pipe upper end is higher than 3 ~ 5mm of strengthening rib in addition and has guaranteed that A regional liquid and partial gas pass through the coil pipe and get into B region, and partial gas passes through the reinforced pipe and gets into B region, reaches the maintenance pressure balance, reduces the interior liquid velocity of flow of coil pipe, prevents that liquid from getting into B region because the too fast foaming of velocity of flow runs the material, improves heat exchange efficiency's purpose.
