Abstract
The utility model relates to a heavy substance discharge radiating system for a heavy substance tower of a sec-butyl alcohol refining unit of a methyl ethyl ketone device, and the system is mainly used for solving the problem that a large quantity of circular cooling water is wasted due to much air transportation time for heavy substances separated from the bottom of the cooling tower of a cooler in the prior art. The system is characterized in that the bottom of the heavy substance tower (1) is connected with the inlet of a radiator pipe (2); the outlet of the radiator pipe (2) is connected with a pump (3); the inlet of the pump (3) is connected with a thermometer (4); and the front and rear pipelines of the radiator pipe (2) are connected with a valve respectively. By utilizing the heavy substance discharge radiating system for the heavy substance tower of the sec-butyl alcohol refining unit of the methyl ethyl ketone device, the circulating water can be remarkably saved, the overhauling expense is reduced, and the energy-saving effect is obvious.
Description
Technical field
The utility model relates to the outer place system of a kind of methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge in the petrochemical industry, and particularly a kind of methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffuses hot system outward.
Background technology
Petrochemical plant MEK process units, heavies tower are to utilize sec-butyl alcohol and heavies boiling-point difference, near under the normal pressure with the two separation; The sec-butyl alcohol boiling point is 100 ℃; The heavies boiling point is more than 130 ℃, and column bottom temperature is controlled at 145 ℃, and sec-butyl alcohol is steamed to cat head; Reclaim sec-butyl alcohol, the isolated heavies of Jiang Tadi is intermittently sent the tank field outside with pump after being cooled to 80 ℃ with cooler.Because the growing amount of heavies is little, just sent outside once at a distance from several hours.It is shorter to send time ratio outside, generally has only a few minutes.According to the equipment protection requirement, the heavies cooler most of the time is wasted a large amount of recirculated cooling waters and cooler recondition expense all in air transport.
Summary of the invention
The utility model technical problem to be solved is to overcome isolated heavies at the bottom of the cooler cooling tower that exists in the background technology because the problems of a large amount of recirculated cooling waters of many wastes of air transport time; And provide a kind of methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge to diffuse hot system outward; This methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffuses hot system outward and can save a large amount of recirculated waters, reduces recondition expense.
The utility model solves its problem and can reach through following technical scheme: this methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffuses hot system outward and comprises heavies tower, pump; Connect heat radiation comb inlet at the bottom of the heavies Tata of being counted; The outlet of heat radiation comb connects pump, and the pump intake place is connected to thermometer; Be connected to valve respectively on the pipeline before and after the heat radiation comb.
Described heat radiation comb is identical with capacity at the bottom of the heavies Tata.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: this methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffuses hot system outward owing to adopt said structure, designs one group of heat radiation comb consistent with capacity at the bottom of the tower, adds a thermometer at the pump intake place; During convey materials, the natural cooled materials in the heat radiation comb has been carried when finishing, when the pump intake temperature is raised to 145 ℃; The material of heat is put into the heat radiation comb at the bottom of the heavies Tata; Termination of pumping is carried after letting thermal material in the comb naturally cool to 80 ℃, like this cooler at the bottom of the cancellation application tower again; The cooler cost of overhaul at the bottom of annual a large amount of recirculated waters of saving and the tower, energy-saving effect is obvious.
Description of drawings:
Accompanying drawing 1 is the system flow sketch map of the utility model.
Among the figure: 1-heavies tower, the 2-comb that dispels the heat, 3-pump, 4-thermometer.
The specific embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing 1; This methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffuses hot system outward and comprises heavies tower 1, pump 3; Connect heat radiation comb 2 inlets at the bottom of heavies tower 1 tower of being counted; 2 outlets of heat radiation comb connect pump 3, and pump 3 porch are connected to thermometer 4, are used to show the temperature of carrying heavies; Be connected to valve respectively on the heat radiation comb 2 front and back pipelines.Described heat radiation comb 2 is identical with capacity at the bottom of heavies tower 1 tower.
When this methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffused hot system convey materials outward, material got into the heat radiation comb.Add a thermometer at the pump intake place; Send the heavies temperature outside in order to monitoring; When the pump intake temperature is raised to 145 ℃, explain that the natural cooled materials in the heat radiation comb has been carried, the material of heat gets into the heat radiation comb at the bottom of the heavies Tata; Termination of pumping is carried after letting the thermal material of heat radiation in the comb naturally cool to 80 ℃ again.
Claims (2)
1. a methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge diffuses hot system outward; Comprise heavies tower (1), pump (3); It is characterized in that: connect heat radiation comb (2) inlet at the bottom of heavies tower (1) tower of being counted; Heat radiation comb (2) outlet connects pump (3), and pump (3) porch is connected to thermometer (4); Be connected to valve respectively on the pipeline before and after the heat radiation comb (2).
2. methyl ethyl ketone plant sec-butyl alcohol refined unit heavies tower weight pledge according to claim 1 diffuses hot system outward, it is characterized in that: described heat radiation comb (2) is identical with capacity at the bottom of heavies tower (1) tower.
