Abstract
The utility model discloses a composite cooler for cooling an effluent of hydrogenation reaction. An axial flow fan is arranged at the upper part of the cooler, a water tank is arranged at the bottom of the cooler, a water pump is used for pumping water in the water tank to a spray system, an air cooling tube bundle using air for cooling is horizontally arranged below the axial flow fan and is connected with a horizontally arranged evaporation tube bundle, the spray system is arranged between the air cooling tube bundle and the evaporation tube bundle, and an inlet grid is arranged between the spray system and the water tank. According to the utility model, the air cooling tube bundle is used for cooling a process fluid entering the evaporation tube bundle, thus avoiding points on which water is easily scaled, effectively slowing down the scaling on the outer surface of a heat exchange tube, improving the heat exchange efficiency and prolonging the service life and reducing operation cost; and the air cooling tube bundle using the air for cooling is used, so air can take away a considerably great part of heat, thus reducing heat exchange of an evaporation section to cause relatively low water evaporation amount and saving valuable water resources.
Description
Technical field
The utility model relates to gas and liquid cools condensation technology, specifically a kind of compound cooler for cooling hydrogenation reaction effluent.
Background technology
The imperfect components such as S, the N of hydrocracking unit will remove hydro carbons in the refining target product in, O, therefore have a large amount of H
2s, HCl, NH
3, the material such as HCN generates, these materials are met water and are generated NH
4cl, NH
4the salts such as HS, wherein H
2s, Cl ion and ammonium salt are very large to the corrosion harmfulness of equipment, sometimes also have uncontrollable strong exothermal reaction and occur.
The high-pressure air cooler system is one of key equipment in hydrocracking unit, has high temperature, high pressure, faces hydrogen, inflammable, explosive, poisonous characteristics, belongs to special equipment.In petrochemical industry, high-pressure air cooler for hydrogenation service is restrained main two kinds of material of main part: carbon steel, Incoloy825 or equivalent material at present.
At present, ASSOCIATE STATISTICS shows that the high-pressure air cooler of carbon steel tube bank has generation excessive erosion more than 85% to reveal, and this station air cooler is in facing hydrogen system, and the very long one section flow process in front and back, without the partition measure, is processed once go wrong to stop; Although Incoloy825 can move under this operating mode, corrosion resistance is strong, successful experience is also arranged abroad, invests very large.Air cooler is because the air side heat transfer coefficient is low, and required film-cooled heat is large, and floor space is also large, invests very highly, and easily is affected by the external environment, and in summer, the problem under temperature is fallen not may occur.
The utility model content
In order to solve, the easy corrosion of existing carbon steel tube bank air cooler is revealed, heat exchange efficiency is low, the problem that anti-corrosive alloy material tube bank air cooler cost is higher, heat exchange efficiency is low, the utility model provides a kind of compound cooler for cooling hydrogenation reaction effluent.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of compound cooler for cooling hydrogenation reaction effluent, comprise axial flow blower, the air cooling tube bank, spray equipment, steam-generating bank, water pump and water tank, wherein, axial flow blower is arranged on the top of cooler, water tank is arranged on the bottom of cooler, water pump is delivered to spray equipment by the water in water tank, utilize air cooled air cooling tube bank be horizontally set on the below of axial flow blower and be connected by pipeline with horizontally disposed steam-generating bank, described spray equipment is arranged between air cooling tube bank and steam-generating bank, be provided with air intake grid between spray equipment and water tank.
Be provided with water collection device between described spray equipment and air cooling tube bank, for collecting airborne steam.
Beneficial effect: it is cooling that the utility model is restrained the process fluid that will enter steam-generating bank by air cooling, avoid the easy fouling point of water, effectively slowed down the scale formation of heat exchange pipe external surface, improved the heat exchange efficiency of equipment 30-50%, and significantly improved service life, reduced operating cost; Air cooled air cooling tube bank, make air take away the heat of quite a few, thereby reduced the exchange heat of evaporator section, makes the evaporation of water amount relatively low, saved valuable water resource, also makes its one-time investment reduce 30-40%; The steam that the air that the utilization of air cooling section is introduced from bottom and evaporator section produce is mixed to form humid air as cooling medium, before entering atmosphere, the air cooling section is carried out to the cooling of Wind Volume, the large temperature difference, makes air cooling and evaporating cold share a blower fan; The cooling needs that can meet heat exchange of air cooling section air, get final product anhydrous dry operation in the winter time, the requirement that reached water saving, economize on electricity, economizes on resources, thus greatly reduce operating cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, axial flow blower, 2, air cooling tube bank, 3, water collection device, 4, spray equipment, 5, steam-generating bank, 6, air intake grid, 7, water pump, 8, water tank.
The specific embodiment
