The vaporization and refrigeration system is characterized in that the vaporization and refrigeration system comprises a raw material tank (1), a filter (2), an evaporator (3), a heat exchange water tank (4), a pump (5), a chilled water tank (6) and a cooling device (7), wherein an outlet of the raw material tank (1) is connected with an inlet of the filter (2); an outlet of the filter (2) is connected with an inlet of the evaporator (3); the evaporator (3) is arranged in the heat exchange water tank (4); an outlet of the heat exchange water tank (4) is connected with an inlet of the chilled water tank (6) through the pump (5); an outlet of the chilled water tank (6) is connected with a cooling water inlet of the cooling device (7); and a cooling water outlet of the cooling device (7) is connected with an inlet of the heat exchange water tank (4). By adopting the liquid ammonia vaporization and refrigeration system, the utility model avoids the loss of absorption heat, relieves the pressure of other production equipments due to the use of chilled saltwater, lessens the running cost of a refrigerator, can play a role of energy conservation and consumption reduction and reduces the manufacturing cost.
Description
(1) technical field
The utility model relates to a kind of liquefied ammonia vaporization refrigeration system, belongs to technical field of chemical.
(2) background technology
In the process of producing the pesticide intermediate isophthalodinitrile, use a kind of primary raw material ammonia.Ammonia is to make by the liquefied ammonia vaporization.Mainly be by liquefied ammonia heater heating liquefied ammonia, make it vaporization, keep ammonia pressure about 0.4MPa.Every isophthalodinitrile generates line and consumes about 9 tons in liquefied ammonia every day.The heat of vaporization of ammonia is 327.3 kcal/kg, and per hour vaporization need to absorb 122737.5 kilocalories of heats, and promptly the liquefied ammonia refrigerating capacity hourly of vaporizing is 122737.5 kilocalories.
In original production process, the liquefied ammonia vaporization absorbs the living cold of hot water thermal volume production and directly slatterns.And the employed cold of workshop is to prepare chilled brine by refrigerator, expends a large amount of electric energy.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of refrigerating capacity that liquefied ammonia vaporization is produced preparation chilled brine that is used is provided, and can play liquefied ammonia vaporization refrigeration system energy-saving and cost-reducing, that reduce cost.
The purpose of this utility model is achieved in that a kind of liquefied ammonia vaporization refrigeration system, it is characterized in that it comprises head tank, filter, evaporimeter, heat-exchanging water tank, pump, freezing water tank and uses cool equipment,
Described head tank outlet links to each other with described filter inlet, and described filter outlet links to each other with described evaporator,
Described evaporimeter is positioned in the described heat-exchanging water tank, the outlet of described heat-exchanging water tank links to each other with described freezing water tank import by pump, described freezing water tank outlet links to each other with the cool equipment cooling water inlet with described, and the described cool equipment coolant outlet of using links to each other with described heat-exchanging water tank import.
This practical novel liquefied ammonia vaporization refrigeration system of use has avoided absorbing the loss of heat, has alleviated the pressure of other production equipment use chilled brine, has alleviated the operating cost of refrigerator, can play energy-saving and cost-reducing effect, has reduced production cost.
(4) description of drawings
Fig. 1 is the utility model liquefied ammonia vaporization refrigerant system configurations schematic diagram.
Among the figure:
Head tank 1, filter 2, evaporimeter 3, heat-exchanging water tank 4, pump 5, brine tank 6, usefulness cool equipment 7, ball-cock assembly 8.
(5) specific embodiment
Referring to Fig. 1, liquefied ammonia that the utility model relates to vaporization refrigeration system is mainly formed by head tank 1, filter 2, evaporimeter 3, heat-exchanging water tank 4, pump 5, freezing water tank 6 with cool equipment 7,
Head tank 1 outlet links to each other with filter 2 imports, and filter 2 outlets link to each other with evaporimeter 3 imports,
Described heat-exchanging water tank 4 imports are provided with ball-cock assembly 8.
Operation principle:
Liquefied ammonia is removed impurity from head tank 1 through the filter 2 that contains the ordinary carbon steel screen pack, enters evaporimeter 3 then, carries out heat exchange with the salt solution of heat-exchanging water tank 4, and making liquefied ammonia be vaporized into ammonia derives from evaporimeter 3, for isophthalodinitrile production use,
The cold that liquefied ammonia vaporization produces forms 0 ℃ of left and right sides chilled brine with the brine freezing in the heat-exchanging water tank 4, is collected into the high-order freezing water tank of placing 6 by pump 5 again, uses cool equipment 7 coolings to other; Hot salt brine after the heat exchange is preferentially got back to heat-exchanging water tank 4 and is recycled.
The salt solution liquid level can be carried out control automatically with stainless steel floating ball valve 8 in the heat-exchanging water tank 4.
