Abstract
The utility model discloses a pre-contact tank cooling device, which belongs to a production device of polypropylene, and comprises a pre-contact tank and two material feed lines connected with the pre-contact tank, and is characterized in that: a heat exchanger is disposed on the two material feed lines respectively. The two independent heat exchangers are additionally arranged on the two material feed lines connected into the pre-contact tank, therefore, a material entering the pre-contact tank can be cooled independently in advance, so as to match a temperature control loop of the pre-contact tank, effectively control the temperature of the pre-contact tank, match the production of polypropylene, improve the quality of polypropylene products, and reduce unit consumption of catalyst.
Description
Technical field
The utility model relates to a kind of polypropylene English name: the Polypropylene production unit of (being called for short PP), particularly relates to a kind of pre-contact jar refrigerating unit.
Background technology
At present, in polyacrylic production process, the temperature control of pre-contact jar is a key parameter, affects the quality of product and the unit consumption of catalyzer, in actual production process, though pre-contact jar is provided with a temperature control loop, in summer, weather is too hot, cause the temperature of pre-contact jar too high, thereby surpass working temperature, influence the quality of product, and the unit consumption of catalyzer is increased.
Have based on this, make the utility model
The utility model content
At the problems referred to above, the purpose of this utility model provides a kind of quality that improves polypropylene product, reduces the pre-contact jar refrigerating unit of the unit consumption of catalyzer.
The purpose of this utility model is achieved in that a kind of pre-contact tank cooling device, comprises pre-contact tank, and two material inlet wires that link to each other with pre-contact tank, it is characterized in that: respectively add respectively heat exchanger on two material inlet wires.
Further be set to: two heat exchanger one ends that are installed on two material inlet wires link to each other with the chilled water water inlet pipe respectively, and the other end links to each other with the chilled water outlet pipe respectively, and pump links to each other with the chilled water water inlet pipe.
The utility model is by installing respectively two independent heat exchangers additional entering on two material inlet wires that pre-contact tank links to each other, like this, just can the material that enter pre-contact tank be cooled off separately in advance, thereby cooperate the temperature control loop of pre-contact tank, effectively control the temperature of pre-contact tank, cooperate polyacrylic production, improve the quality of polypropylene product, reduce the unit consumption of catalyst.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
In conjunction with shown in Figure 1, pre-contact tank cooling device of the present utility model, comprise pre-contact tank 1, and two material inlet wires 21 that link to each other with pre-contact tank 1 and material inlet wire 22, on two material inlet wires 21 that enter into that pre-contact tank 1 links to each other and material inlet wire 22, respectively add respectively heat exchanger 31 and heat exchanger 32, heat exchanger 31 links to each other with chilled water water inlet pipe 41 respectively with heat exchanger 32 1 ends, the other end links to each other with chilled water outlet pipe 42 respectively, and pump 5 links to each other with chilled water water inlet pipe 41.
The utility model is by installing respectively two independent heat exchangers additional on two material inlet wires 21 that enter into that pre-contact tank 1 links to each other and material inlet wire 22, like this, just can the material that enter pre-contact tank be cooled off separately in advance, thereby cooperate the temperature control loop of pre-contact tank, effectively control the temperature of pre-contact tank, cooperate polyacrylic production, improve the quality of polypropylene product, reduce the unit consumption of catalyst.
