Abstract
An energy-saving device capable of producing refined methanol by using self waste heat is characterized in that two sections of communicated tube sides and two sections of disconnected shell sides together form heating equipment, and a preliminary tower is heated by the waste heat of the system and the steam simultaneously by virtue of the two disconnected shell sides; the heat exchange area of the two shell sides is calculated as follows: according to the heat required by the production load of the preliminary tower and the heat actually produced by the system, the heat exchange area of the waste heat heating section of the system is calculated at first, and then the insufficient heat serves as the amount for calculating the heat exchange area of the steam shell side externally required by the lower half section; the two tube sides are independent from each other and are connected via a cylinder body; the two disconnected shell sides are both provided with inlet and outlet connecting pipes; and methanol residual liquid and externally required steam respectively pass the upper and the lower shell sides that are disconnected. In the device, two heating medium can heat one medium without mutual communication, thereby greatly solving the difficulty that two heating medium can hardly heat one medium simultaneously.
Description
Technical field:
The utility model belongs to thick pure rectifying production technical field, relates in particular to a kind of device that three tower continuous rectification methods are produced smart alcohol.
Background technology:
The technology that present China utilizes the thick pure rectifying again of synthetic ammonia connection alcohol production to obtain the smart alcohol employing of finished product is two towers or three tower continuous rectification method production technologies substantially, but what generally adopt is that simple usefulness is given pre-tower heating for steam outward, and its technological deficiency of such explained hereafter is:
1, because the simple steam that adopts is given pre-tower heating, fluctuate for steam outward and can cause pre-tower to add thermally labile when frequent, be unfavorable for separate impurities in the tower.
2, the main production cost of methanol rectification is exactly the consumption of steam, and simple gives pre-tower heating with steam, has increased steam consumption quantity greatly, has just increased smart pure production cost.
3, because the used heat of self system is not utilized, but discharge system, cause industrial waste heat to efflux and pollute with environment used heat by traditional handicraft.
4, because the used heat of self system directly effluxes, cause heat energy not to be fully utilized, cause energy waste.
Summary of the invention:
For overcoming the technological deficiency that exists on the present methanol rectification production technology device, the utility model discloses a kind of energy saver that utilizes system self used heat to produce methanol rectification.
The technical scheme that the utility model is dealt with problems is:
A kind of energy saver of producing the smart alcohol of methyl alcohol, pre-tower heater (reboiler) is carried out inside transformation, with original one section tube side heating, change two sections tube side heating into, two tube side UNICOMs, in walk the heated medium material, but double-shell is UNICOM not, wherein the upper semisection shell side is walked external demand heating steam, and the lower semisection shell side is walked hot methanol raffinate heating, it is characterized in that: by the tube side of two sections UNICOMs and two sections not the shell side of UNICOM constitute a firing equipment, utilize two mutually not the shell sides of UNICOM finish the heating process that system's used heat and steam carry out pre-tower separately simultaneously, the double-shell heat exchange area according to the heat that adds that adds heat and the actual generation of system's used heat of pre-tower production load needs, calculates the heat exchange area of system's waste heat section, the not enough heat that adds, just as lower semisection external demand steam shell side heat exchange area amount of calculation, two tube sides are independent separately, link to each other with one section cylindrical shell, double-shell is not communicated with, each have into, go out to take over, methyl alcohol raffinate and external demand steam are gone on respectively separately, following two sections mutual not shell sides of UNICOM.
The advantage of technical solutions of the utility model is:
1, in this device two kinds of different caloric value matter that add is heated same heated medium simultaneously, and be not communicated with mutually, solved the difficult problem that two kinds of heat mediums heat same heated medium simultaneously well.
2, made full use of the former system's used heat that is directly emitted of system, by this device, system's used heat is utilized fully, and the smart alcohol consumption of former technology ton methyl alcohol steam is about 1.15 tons, now reduce to 1.05 tons, be that the smart alcohol of methyl alcohol per ton is used about 0.1 ton of steam less,, produce 200000 tons of calculating of the smart alcohol of methyl alcohol per year with our present actual production load, through technical solutions of the utility model, annual few with steam about 20,000 tons, by 120 yuan of steam per ton, annual just can saving production cost is 2,400,000 yuan.
3, the utility model has thoroughly effected a radical cure in the smart pure growth course of methyl alcohol system and directly effluxes used heat and cause environment used heat pollution problems.
4, owing to utilize system's used heat from heating, the stability of pre-tower operation obviously strengthens, and the impurity separating effect is obvious, helps improving the quality of the smart alcohol of finished product methyl alcohol.
Description of drawings:
1, accompanying drawing 1 is a structural representation of the present utility model
2, accompanying drawing 2 is process flow diagrams of the present utility model
In the accompanying drawings, the 1st, heated medium steam (vapor) outlet, the 2nd, hot methanol raffinate heating import, the 3rd, the import of external demand Steam Heating, the 4th, heated medium import, the 5th, the outlet of external demand steam condensate, the 6th, the cold liquid outlet of hot methanol raffinate.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
A kind of energy saver of producing the smart alcohol of methyl alcohol, by two sections tube sides that are connected and two sections integral heaters that mutual disconnected shell side constitutes, that walks in two tube sides that are communicated with is subjected to the thermal material medium, what mutual disconnected double-shell was walked respectively is methyl alcohol raffinate and the heating steam of last need, two heat mediums are independently given the medium heating of assigning separately, are independent of each other.
Technological process of the present utility model such as accompanying drawing 2 signals, its operation principle is: utilize an integral heater that used heat liquid and the external demand heating steam that original system directly effluxes is well combined, promptly made full use of the used heat of system, the not enough heat that adds well can be solved by non-interfering external demand steam again, saved energy consumption to greatest extent.While is owing to the stability of the heat enthalpy value of system's used heat, so the heat that adds of pre-tower will be relatively stable, the stability of the production of pre-tower increases greatly, is to kill two birds with one stone.
