Heating chamber: (see picture), the heating chamber is tube-type, double-layer insulation, up and down through the nozzle elbow to communicate with the evaporation chamber, the upper hole cover is used for cleaning the tube, and the first heating chamber (2) is equipped with steam pressure Tables, safety valves to ensure production safety.
Evaporation chamber: (see figure) 1 and 2, double-layer structure of evaporation chamber, heat insulation, mirror on the front for the operator to observe the evaporation of the liquid, the top hole is easy to replace the variety when cleaning the room, and Vacuum gauge, temperature gauge, easy to observe and master the indoor vacuum and liquid temperature.
Water receiving device: The water receiving device is located at the lower part of the evaporation chamber, and the remaining steam and condensed water discharged from the heating chamber are separated by the steam separator. The steam enters the second effect heating chamber from the upper pipe or is cooled by the inlet cooler, and the condensed water flows into the lower layer through the pipe. Discharge regularly.
Cooler: The cooler is a four-way tube type, and the lower water receiver is used to receive condensed water and is periodically discharged.
V. Working principle Primary steam (boiler steam) enters the first-effect heating chamber to heat the material liquid. At the same time, under the action of vacuum, the first-stage evaporation chamber is sprayed from the nozzle, and the liquid returns from the curved tube to the heating chamber, and is again heated. Spraying into the evaporation chamber to form a circulation, the liquid is sprayed into the evaporation chamber to form a mist, the water evaporates rapidly, and the second steam evaporated into the second-effect heating chamber to heat the second-effect liquid, enters the cooler, and is cooled by the cooling water. Condensed water, flowing into the water receiver and automatically entering the drainer. The water in the liquid is continuously evaporated, the concentration is increased, and the concentration is increased to the required specific gravity. The paste is discharged from the paste, and the cooling water is exchanged by the cooler. The water temperature is raised to 30-40 ° C and sent to the water main pipe. For the entire plant or sent to the cooling tower for recycling.
Sixth, equipment installation
1. Installation according to the installation drawing.
2. The foundation is 100-200# concrete structure.
3. The process pipeline has a great influence on the performance of the equipment. It shall not be arbitrarily changed according to the size, size, angle and position of the pipe.
Seven, the operation and operation of the equipment
1. Open the vacuum equipment first, open the valve (13, 11, 9, 8, 2), close the valve (17, 16, 12, 10, 7, 6, 5, 4, 3), and take the first and second vacuum After reaching 0.04Mpa, open the feed (3, 5, 7), add one effect liquid to the half of the middle mirror of the evaporation chamber, close the valve (3), open the steam valve (1) to heat up and open the valve (6) The liquid enters half of the middle half mirror of the second effect evaporation chamber, closes the valve (6), opens the cooling water valve (15), cools the vaporized body, and begins normal concentration.
2. According to the evaporation speed of each effect, continue feeding and replenish it to the original position.
3. Drainage: The regulating over-water valve (11, 13) is discharged by the drainer.
4, collecting paste: due to high evaporation temperature, high concentration, large ratio, easy to paste, the second effect concentrate into a concentrated effect, close the valve (9), open the valve (17), destroy the second effect vacuum valve To 0, open the valve (3, 5, 6), the material is restored after one effect, and work. When the concentration of the liquid solution reaches the required specific gravity, close the steam valve (1), open the valve (16), destroy one. The vacuum gauge pressure drops to 0, and the valve (3, 4) is opened to collect the paste, and the recovery is completed after completion.
In order to keep the inner wall of the heating chamber tube clean, one effect must be washed by water for 10 minutes, and the drainage should be stopped.
Eight, equipment cleaning
1. For the same variety production, the steam pressure of the first-effect heating chamber is kept at around 0.09Mpa/cm. If the steam pressure is significantly increased, the plaster is attached to the pipe wall to form the scale, which affects the heat transfer. Open the heat-effect chamber hole cover, use a round steel brush to remove the drug residue and restore the production. It takes one time to clean the brush once for one effect, and clean it once every two months.
2, change the variety of cleaning: boil with 10% caustic soda for half an hour, then clean the inside of the equipment.
Nine, equipment failure and elimination
malfunction | the reason | exclude |
Insufficient vacuum | Cooling water pressure is not enough | Increase the flow of cooling water and increase the inlet pipe. |
Produce foam | There are bubbles in the liquid, the steam is unstable, and the vacuum is not enough. | Open the effect vent valve (16) Two-effect venting valve (17) |
