Abstract

The invention discloses an air-cooling-type tubular condensation device, wherein the condensation device comprises a condenation tube, a fin and a gas-liquid separation chamber; air can be taken as a cooling medium, and the mixture of steam and other gases can be condensed into a liquid, and gas and liquid separation is realized.

Description

A kind of air-cooled tubular type condensing unit

One, technical field

The present invention relates to the installation for steam condensation field, refer in particular to a kind of air-cooled tubular type condensing unit that can the mixture of steam and other gases be condensed into liquid and realize gas-liquid separation.

Two, background technology

Steam-sprayed refrigerator generally adopts mixing condenser or shell-and-tube heat exchanger.When application mix formula condenser, cooling water descends from last spray, and steam feeds from the bottom, directly contacts with the cooling water that sprays during rising, and condensation becomes liquid phase, and cooling water then heating temperature raises.Because cooling water can be dissolved with a certain amount of air at a lower temperature, wherein air was overflowed when temperature raise, and therefore vavuum pump need be set extract out, had increased input and operating cost.When using shell-and-tube cooler,, cause cooling effectiveness to reduce because liquid phase and gas phase media are present in the condenser simultaneously.For addressing the above problem, the present invention has designed a kind of air-cooled, can the mixture of steam and other gases be condensed into liquid and realize the trumpet cooler of gas-liquid separation.

Three, summary of the invention

The present invention proposes a kind of air-cooled tubular type condensing unit; Structure comprises: gas-liquid separation chamber, condenser pipe, fin; Wherein gas-liquid separation chamber is divided into a plurality of cavitys by the dividing plate that stretches into below the metal line; The demarcation strip lower end is in the position near gas-liquid separation chamber bottom, but is not connected with the bottom, makes that the liquid in each cavity can flow each other.Condenser pipe vertically is welded on the gas-liquid separation chamber top.The import condenser pipe of condenser stretches into below the metal line, and the outlet condenser pipe of condenser is more than metal line.Other condenser pipe one ends stretch into below the metal line; The other end strides across the inside that demarcation strip probes into another cavity; And more than liquid level, a plurality of condenser pipes distribute successively, make gas after condenser pipe import entering gas-liquid separation chamber; Be introduced under the liquid level, gas gets into next cavity from the opening that another root condenser pipe is positioned on the liquid level then.Be welded with a plurality of fins on the every condenser pipe, when air-flow externally flows through fin under the fan action, heat taken away.Fin thickness is 1 millimeter, and width is 6 centimetres to 10 centimetres.There are an inlet and a liquid outlet in the gas-liquid separation chamber two ends, and the inlet position is higher, and the liquid outlet position is lower.The indoor metal line of gas-liquid separation position must maintain certain altitude, makes the opening of demarcation strip lower end, condenser pipe lower end all below metal line, and the opening of condenser pipe upper end is more than metal line.

Four, description of drawings

Below in conjunction with accompanying drawing, the present invention is described further.

Fig. 1 is the front section view of this device.

Fig. 2 is the A-A cross-sectional view of this device.

The position of marking is respectively among the figure: 1, import condenser pipe; 2, condenser pipe; 3, fin; 4, metal line; 5, gas-liquid separation chamber; 6, liquid outlet; 7, inlet; 8, outlet condenser pipe.

Five, the specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present invention is described further.

Steam gets into condenser pipe 2 from steam inlet 1, flows and condensations gradually along condenser pipe 2, and the liquid after condensing gets into the cavity of gas-liquid separation chamber 5 with the gas that does not condense.Because below 4, liquid imports the liquid of gas-liquid separation chamber 5 to condenser pipe 2 one ends at metal line, gas is overflowed and is got into next cooling procedure from next root condenser pipe 2.Through repeats condensation process repeatedly, last incondensible gas is overflowed from steam (vapor) outlet 8, and liquid is stayed in the gas-liquid separation chamber 5.At last through liquid outlet 6 and inlet 7 control metal line height.Blower fan can be placed in the condenser outside, quickens air and flows, and improves cooling velocity.
