Novel water jet condenser with multiple closed water chambers and jet flow control valve

Abstract

The invention discloses a novel water jet condenser with multiple closed water chambers and a jet flow control valve used in a sugar refinery. The water jet condenser is characterized in that a water chamber of the condenser is divided into an opened big water chamber and a plurality of closed small water chambers; each water chamber is respectively provided with a jet nozzle and a spray nozzle; a plurality of closed small water chambers are respectively controlled by a plurality of pneumatic or electric butterfly valves installed on the outside of the condenser; the lower part of the condenser is provided with a monolayer or multilayer jet flow control valve for making the size of the central round aperture of a jet flow passage keep a coaxial change; the jet nozzle and the spray nozzle in each water chamber are respectively cooperated with the monolayer or multilayer jet flow control valve to control the water supply amount of the condenser, so that a high vacuum degree of the condenser can be always kept in the production.

Description

technical field [0001] The invention relates to a novel water jet condenser with multiple closed water chambers and jet regulating valves, which is especially suitable for vacuum systems in light, chemical and pharmaceutical factories. Background technique [0002] Before 2005, the wet water jet condenser commonly used in domestic sugar factories was the TDP water jet condenser. So far most of the domestic sugar factories from south to north are using this type of Indian-style high-efficiency condenser (including domestic imitation type and domestic improved type). But after nearly 10 years of use, the fatal flaws of such Indian-style high-efficiency condensers have gradually been exposed. For example: in the early stage of pressing, under the production conditions of colder weather, lower water temperature and stable steam volume, the vacuum degree of most of these high-efficiency condensers is still relatively high, which can reach 0.086-0.09MPa. However, when the produc...

Problems solved by technology

However, when the production conditions change, such as when the amount of steam to be processed increases or the cooking time needs to be shortened, or the temperature of the inlet water rises due to hot weather, the vacuum degree of the condenser will be seriously reduced to 0.080-0.082MPa, Does not meet the technological requirements for boiling sugar
