Full automatic control water jet condenser with characteristics of concentric diameter changing throat part, temperature control, constant water pressure and adjustable nozzles

Abstract

The present invention discloses a full automatic control water jet condenser with characteristics of a concentric diameter changing throat part, temperature control, constant water pressure and adjustable nozzles, wherein the full automatic control water jet condenser is used in sugar refineries. The full automatic control water jet condenser is characterized in that part of spray nozzles and jet nozzles arranged in a water chamber are nozzles provided with a pneumatic opening and closing control device, a throat part of the condenser is provided with a concentric diameter changing throat part device, and the pneumatic opening and closing controlled nozzles and the concentric diameter changing throat part device can jointly act and perform adjustment control according to a water temperature and a water supply amount of water entering the condenser water chamber. According to the present invention, a pressure transmitter for detecting a vacuum degree of a container (a sugar boiling tank or an evaporation tank), a temperature transmitter for detecting a temperature of a material (a syrup and a sugar paste) inside the container, and a pressure transmitter for detecting water pressure inside the water chamber jointly adjust and control an opening degree of an automatic control water inlet valve, such that the condenser can achieve a high vacuum degree under a normal production condition, and can achieve a preset vacuum degree and a preset material temperature during production condition changing, wherein the existing wet type water jet condensers used in sugar refineries at home and abroad do not have the advantages of the condenser of the present invention.

Description

technical field [0001] The invention relates to a wet water injection condenser, which is especially suitable for the vacuum system of boiling sugar and evaporating sugar in a sugar factory. Background technique [0002] At present, the automatically controlled wet water jet condensers used in domestic and foreign sugar factories generally have two major defects: [0003] (1) The diameter of the throat of all types of water jet condensers is fixed, and the number and diameter of nozzles in the water chamber are also fixed and normally open (or normally closed). The throat diameter of the condenser cannot be adjusted during production, and the opening and closing of the normally open (or normally closed) water chamber nozzle cannot be adjusted (if you want to adjust, you can only stop the machine or block the nozzle or open the nozzle), under stable production conditions , the vacuum degree is guaranteed. However, when the production conditions change, the amount of water c...

Problems solved by technology

However, in actual production, when the circulation and convection of the material in the container (especially massecuite with high viscosity) is not good, the actual temperature of the material and the temperature of the material (boiling point) corresponding to the degree of vacuum often have a considerable deviation, which is obviously It will mislead production, and in severe cases, it will bring great economic losses to the enterprise
