Background

It is known that in the vacuum distillation process, oil vapor needs to be cooled by a condenser to obtain liquid oil, and the condensing medium of the existing condenser is circulating water, so that the oil vapor can be cooled, a large amount of heat is dissipated, and the energy consumption is increased. The cooling part of the existing reduced pressure distillation system is generally a horizontal condenser and vertical storage tank structure, the occupied space is large, an auxiliary structure is required to support the condenser, and the installation work amount is large.

Disclosure of Invention

In order to overcome the deficiency in the background art, the utility model discloses a vacuum condensation tower.

In order to realize the purpose, the utility model adopts the following technical scheme:

the utility model provides a vacuum condensation tower, including the tower body and set up the jar of keeping in at the bottom of the tower, the top of tower body is equipped with the oil vapor entry that is linked together with tower body center tube side, two-layer shell side A and shell side B that do not communicate about being equipped with in the tube side outside, tube side and shell side A, be equipped with the cavity between the shell side B, be equipped with raw oil in the shell side A, be equipped with the cooling water in the shell side B, both sides are equipped with the raw oil export respectively about shell side A's the outside, the raw oil import, both sides are equipped with the cooling water export respectively about shell side B's the outside, the cooling water import, be located and.

The upper end of the tube pass of the vacuum condensation tower is connected with the oil vapor inlet, and the lower end of the tube pass is communicated with the temporary storage tank at the bottom of the tower.

The vacuum condensing tower is provided with a plurality of layers of baffle plates which are arranged in a staggered manner at intervals up and down and in parallel left and right in a shell pass A and a shell pass B, a gap is arranged between the right side of the baffle plate arranged on the left side and the right side of the inner wall of the shell pass A or the shell pass B, and a gap is arranged between the left side of the baffle plate arranged on the right side and the left side of the inner wall of the shell pass A or the shell pass B.

Since the technical scheme is used, the utility model discloses following beneficial effect has:

the vacuum condensing tower of the utility model has the advantages that the oil vapor is introduced into the tube side, the raw oil is introduced between the shell side A and the tube side, and the cooling water is introduced into the shell side B, so that the oil vapor is cooled in two stages, and the cooling water is auxiliary cooling to play a role in supplementing cooling; the utility model has simple structure and convenient use, utilizes the oil gas evaporated by the cooling of the raw oil, effectively utilizes the heat which is originally dissipated, and greatly improves the utilization rate of energy; the mode that condenser and storage tank vertical combination, effectual saving installation cost and area.

Fig. 1 is a schematic structural diagram of the present invention;

in the figure: 1. a raw oil outlet; 2. shell pass A; 3. a tube pass; 4. a cooling water outlet; 5. shell pass B; 6. a vacuum pumping port; 7. a temporary storage tank at the bottom of the tower; 8. a cooling water inlet; 9. raw oil inlet; 10. an oil vapor inlet; 11. and (7) a baffle plate.

Detailed Description

The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.

Combine figure 1 vacuum condensation tower, including the tower body and set up at the tower bottom of the tower jar 7 of keeping in, the top of tower body is equipped with the oil vapor inlet 10 that is linked together with tower body center tube side 3, two-layer shell side A2 and shell side B5 that do not communicate about being equipped with in tube side 3 outside, tube side 3 and shell side A2, be equipped with the cavity between the shell side B5, be equipped with raw oil in shell side A2, be equipped with the cooling water in shell side B5, both sides are equipped with raw oil export 1 respectively about shell side A2's the outside, raw oil import 9, both sides are equipped with cooling water export 4 respectively about shell side B5's the outside, cooling water import 8, be located and be equipped with vacuum extraction opening 6 on the shell of jar 7 upper portion tower bottom of keeping in.

The upper end of the tube pass 3 of the vacuum condensation tower is connected with an oil vapor inlet 10, and the lower end of the vacuum condensation tower is communicated with a temporary storage tank 7 at the bottom of the tower.

In the vacuum condensation tower, a plurality of layers of baffle plates 11 which are vertically spaced and are arranged in parallel in a staggered manner from left to right are arranged in a shell pass A2 and a shell pass B5, a gap is formed between the right side of the baffle plate 11 arranged on the left side and the right side of the inner wall of the shell pass A2 or the shell pass B5, and a gap is formed between the left side of the baffle plate 11 arranged on the right side and the left side of the inner wall of the shell pass A2 or the shell pass B5.

Implement the vacuum condensation tower, when using, usually raw oil will heat, the raw oil with normal atmospheric temperature lets in shell side A2 by raw oil import 9 now, cooling water lets in shell side B5 through cooling water import 8, the vapor of high temperature lets in tube side 3 through vapor entry 10, carry out the heat transfer to vapor by one-level raw oil, secondary cooling water is as auxiliary cooling, still can not refrigerated oil gas completely cool off in second grade shell side B5 after will passing through one-level shell side A2 cooling, this part of effectual utilization is the heat that will scatter and disappear originally, the utilization ratio of the energy is improved; wherein the tube side 3 is a seamless tube, can effectively improve the pressure grade of the whole equipment, can temporarily store cooled oil in the temporary storage tank 7 at the bottom of the tower, and the vacuum pump provides a negative pressure environment for the whole system through the vacuum pumping hole 6 and guides the steam to flow to the direction.

The part of the utility model not detailed is prior art.

The embodiments selected for the purpose of disclosing the invention, are presently considered to be suitable, it being understood, however, that the invention is intended to cover all variations and modifications of the embodiments, which fall within the scope of the concept and the utility model.
