Description

Chiller

Technical field

The utility model relates to a kind of chilling device, is specifically related to a kind of chilling device that is used for the quick Quench of process gas after the ethylbenzene dehydrogenation technology dehydrogenation reaction.

Background technology

Styrene is important basic Organic Chemicals, mainly as the raw material of producing synthetic plastic, synthetic rubber and synthetic resin etc.Styrene as polymerization single polymerization monomer in process of production, autohemagglutination very easily in the storage process, in order to prevent or to slow down styrene monomer polymerization in process of production, the styrene gas that contains after the dehydrogenation reaction need be cooled down fast, usually be cooled to temperature 60-70 ℃ from temperature 110-130 ℃, promptly contain the saturation temperature of styrene gas under corresponding pressure, because polymerization speed and temperature are exponential relationship, contain that the condensed lime set temperature of styrene gas is lower more to prevent styrene polymerization, be reduced to below 60 ℃ when temperature, cinnamic polymerization is very slow, thereby avoided the generation of polymer, so chilling technology just must be in the shortest time, pressure drop with minimum, the minimum water yield is reduced to saturation temperature under the pressure at that time with material temperature, and chiller promptly becomes an important device.In industrial production, why so important the Quench of styrene dehydrogenation gas and the stable operation of chiller be, its reason is some: (1) is if the chiller chill effect is bad, then must increase the amount of chilled water, put forward amount with water treatment thereby increased follow-up steam, thereby increased the consumption and the operating cost of water stripping steam; (2) in order to prevent that chiller aperture or nozzle from stopping up, on many commercial plants, chilled water can not operative installations itself process condensate water, and directly use the soft water of outer confession, thereby significantly increased the amount of total process condensate water, thereby increased considerably the consumption and the operating cost of water stripping steam; (3) owing in the Quench system, the mechanism complexity of chiller aperture or nozzle aperture or spray nozzle clogging, reason is many-sided, and chiller stops up in case the chiller obstruction has taken place, then can't long term maintenance device steady production, cause and be forced to stop, then can result in greater loss.

For this reason, many patent disclosures technology separately:

Chinese patent CN1155650A discloses a kind of chiller, and this chiller comprises a columnar valve jacket.This valve jacket contains styrene gas by a gas access connector with high temperature and links to each other, and links to each other with refrigerator pipe by a gas vent connector, also has a water injector in this valve jacket.Because chiller adopts comb shape distributor, Quench liquid by the atomizing of distributor short tube.This chiller atomizing effect is poor, chill effect is not good enough, because comb shape distributor adopts the uniform and atomizing of aperture, causes aperture easily to stop up;

Chinese patent CN2692614Y discloses a kind of chiller, be the improvement to Chinese patent CN1155650A, in this patent, the Quench distribution of liquid still adopts the calandria distributor, Quench liquid atomizes by atomizer, and the angle of nozzle and main flow direction is 0-60 °;

Chinese patent CN2747222Y discloses a kind of improvement project of chiller, wish to solve the problem of chiller aperture or spray nozzle clogging, its method is that a curved baffle is set before the calandria distributor, to avoid high-temperature gas directly and comb heat exchange and improve the temperature of chilled water, but, still do not have well to solve the problem of chiller aperture or spray nozzle clogging.

Summary of the invention

The purpose of this utility model is to propose a kind of chiller, to overcome the above-mentioned defective that prior art exists.

Said chiller comprises tubular valve body, tubulose spool, connector, the block valve of both ends open and has the hollow Quench head of cavity;

Described tubulose spool is inserted in the tubular valve body, two ends extend to outside the tubular valve body respectively, one end of described tubulose spool is fixed on an end of described tubular valve body by connector, described Quench head is fixed on the end of described tubulose spool, the cavity of described Quench head is connected with described tubulose spool, and described block valve is arranged on the tubular valve body middle part.

The utility model can be fit into spool valve body easily or removes from valve body, cleans thereby the tubulose spool can be split out, and described block valve can be after splitting out spool, closed valve, thus the formation leak point avoided, guaranteed the safe and reliable of device.

Chiller of the present utility model can be used for gas and cool off fast, especially can be used for as styrene monomer polymerization in process of production, need be with the quick cooling that contains styrene gas after the dehydrogenation reaction.

Chiller of the present utility model, handle identical raw material under identical process conditions, can avoid adding chilled water fully, reduce the circulation chilled water, comparable traditional equipment reduces condensed water total amount 5～10%, has tangible economic benefit, and it is simple in structure, maintenance is convenient, can thoroughly solve blocking problem, can guarantee the efficient, reliable and stable of production process.
