Abstract

The invention discloses an air-cooled gas cooler, which comprises a shell, a cavity in the shell, supporting legs, a gas inlet, a gas outlet, an air inlet, an air outlet and a liquid outlet, wherein the cavity is divided into an upper part and a lower part by a partition board; each of the upper part and the lower part comprises a plurality of finned tubes slantways arranged in the cavity; and a plurality of baffle plates are arranged in the cavity. The air-cooled gas cooler can condense most part of waste hot gas into liquid so as to reduce the emission of waste hot steam. The baffle plates are provided, so the heat exchange efficiency is improved, discharge of condensed water is facilitated, and the environment can be effectively protected.

Description

Air-cooled gas cooler

Technical field

The present invention relates to a kind of air-cooled gas cooler, belong to technical field of heat exchange devices.

Background technology

Often produce large calorimetric bled steam in the industrial processes, according to the difference of production industry, these hot bled steams may contain some toxic and harmfuls, can not directly be thrown in the air, therefore before discharging, need it is cooled off, further it is processed again.Now, the equipment that most domestic is used for cooling down high-temperature gas mostly is water-cooled cooling equipment, water-cooled cooling equipment part is many, complex structure, quality is heavy, manufacturing cost is higher, be prone in the use procedure leak, the fault such as freezing, fouling, working service inconvenience, because the energy-dissipating devices such as fan, water pump are arranged, its power attenuation is also larger, and the medium water of water-cooled cooling equipment is at present relatively rare resource of China, being used for cooling media too wastes, and should rationally reach effective utilization to it in industrial production.Comparatively speaking, air-cooled employing air is made cooling medium, and swiftly flowing air is directly taken away the heat of high-temperature gas, to reduce the temperature of hot bled steam, this kind cooling device cost is low, simple structure, quality is light, but is the cooling device of a kind of extensive use and energy savings.But the domestic relatively large air cooler for the treatment of capacity that also do not occur at present.The air-cooled cooling equipment of minority mostly is the little small-sized cooling device for the treatment of capacity on the market, and mostly is the open type cooling, if in office operation, hot blast directly discharging can cause indoor temperature sharply to raise, and affects production environment.

Summary of the invention

The invention provides a kind of air-cooled gas cooler, improved heat exchange efficiency, cooling water is easy to the device for transferring outside, alleviates follow-up exhaust-gas treatment difficulty.

The present invention realizes by following technical scheme:

A kind of air-cooled gas cooler, the cavity, supporting leg, air inlet, gas outlet, air inlet, air outlet and the leakage fluid dram that comprise shell, enclosure, described cavity becomes up and down two parts by a baffle for separating, and described upper part cavity and lower part cavity all comprise the some finned tubes that are obliquely installed in inside cavity; Described inside cavity also has several deflection plates.

Described upper part inside cavity has 29 finned tubes, and lower part inside cavity has 28 finned tubes.

Described each finned tube is fixed on the tube sheet.

Beneficial effect of the present invention is:

1. air cooling equipment is condensed into liquid state with most of hot waste gas body, has reduced the discharge capacity of hot bled steam, and has alleviated follow-up exhaust-gas treatment difficulty, has effectively protected environment;

2. the ingenious deflection plate that utilizes of indoor air cooling equipment prolongs cold wind time of staying in equipment, increases heat exchanger effectiveness;

3. the design of inclining fin pipe can make the convenient discharge of condensate liquid.

The specific embodiment

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

Such as Fig. 1 and Fig. 2, front view of the present invention and top view, it is a kind of cold wind formula gas cooler, the cavity 8, the supporting leg 2 that comprise shell 1, enclosure, be arranged in addition air inlet 3, gas outlet 4, air inlet 5, air outlet 6 and the leakage fluid dram 7 on shell 1 surface, air inlet and gas outlet guarantee the circulation of high-temp waste gas inside and outside the cavity finned tube, air inlet and air outlet guarantee the circulation of refrigerating gas inside and outside cavity, and leakage fluid dram has guaranteed the smoothness of condensed fluid discharge outside of the present invention.

Such as Fig. 4 and Fig. 5, be respectively B-B cutaway view and C-C cutaway view among Fig. 1, as can be seen from the figure, cavity 8 adopts a dividing plate 9 to be separated into up and down two parts, and upper part cavity and lower part cavity all comprise the some finned tubes 10 that are obliquely installed in inside cavity.In the present invention, upper part inside cavity has 29 finned tubes, and lower part inside cavity has 28 finned tubes.Finned tube in the upper part cavity evenly is divided into three rows to be arranged, and the finned tube in the lower part cavity also evenly is divided into three rows and arranges.The design of this tilting makes condensed water be more prone to drippage, can easierly discharge outside the cavity of the present invention by leakage fluid dram 7.

For another example Fig. 1, each finned tube is fixed on the tube sheet 11.Because finned tube is circular, in order to guarantee finned tube fixing in cavity 8, adopted this tube sheet 11.Inside cavity also has several deflection plates, is provided with 4 deflection plate E among the present invention, is respectively Ea, Eb, Ec, Ed, can delay the currency of high-temperature gas in cavity, has improved the efficient of heat exchange.Such as Fig. 6, it is the deflection plate cutaway view.On shell 1 of the present invention, also be provided with several visors 12 at different parts, can monitor at any time the air inlet of inside cavity and give vent to anger, air intake and air-out, with and the process of discharge opeing, the equipment that prevents blocks, assurance equipment is unimpeded.

Operation principle of the present invention is: high-temp waste gas enters inside cavity from air inlet, thereby 29 finned tube inside of upper part cavity have been entered, moved to left end by the right-hand member among Fig. 1 slowly along the fin pipe interior, meanwhile, enter cavity from the cold wind of air inlet from the left bottom of cavity, meet with the high-temp waste gas of fin pipe interior and carry out heat exchange, thereby realize cooling.The gas that is cooled continues mobile, arrive the high order end of cavity, enter lower part cavity, then in 28 finned tubes of lower part cavity, move to right-hand member, proceed heat exchange with cold wind, to the low order end place of cavity, discharged by the gas outlet, and the cold wind that carried out heat exchange is discharged from equipment upper end air outlet, and high-temp waste gas condenses into condensed water, discharges from leakage fluid dram.In the process that high-temp waste gas moves in cavity, dividing plate has played and has made the longer effect of high-temp waste gas time of staying in cavity, has improved heat exchanger effectiveness, so that cold wind is utilized effectively.
