Description
Technical field
The present invention relates to the technical field of chemical industry, particularly relate to methyl alcohol heating plant.
Background technology
China is a methanol production big country, and domestic methanol industry exists the problem of production capacity surplus.According to statistics display, last year, China's methyl alcohol production capacity reached 5149.1 ten thousand tons, output 3,129 ten thousand tons, and the device load that goes into operation only has 60.8%, and problem of excess production capacity is given prominence to.Meanwhile, in part industry, such as, in the production process of chemical plant, chemical fertilizer factory, can produce the concomitant output such as thick alcohol, useless alcohol (purity is the methyl alcohol of 55%-75%) in a large number, this kind of thick alcohol, useless alcohol purity are lower, and cost for purification is high, cannot directly apply.Not in statistics.If by the related data statistics of thick alcohol, useless alcohol interior, can reach a conclusion, current China methyl alcohol problem of excess production capacity is protruded, the methyl alcohol thick alcohol that especially purity is not high, useless alcohol cannot make full use of.
On the other hand, modern society's energy and pollution problem are protruded, and methyl alcohol is clean energy resource in theory, if be applied in industrial combustion, the problem of the energy and pollution can be solved, solve again methyl alcohol production capacity surplus, the problem that utilization rate is low, provides a kind of clean energy resource of cheapness.
But in fact, in prior art, the mode of methyl alcohol burning is first through mechanical atomization, then burns, this technology also exists a lot of problem: first, and because atomizing type causes its incomplete combustion, not only during burning, temperature is not enough, and can the pernicious gases such as formaldehyde be produced, contaminated environment; Secondly, this application mode can only use smart alcohol (purity >=95%) as fuel, and smart alcohol price is higher, although low-purity methyl alcohol price is lower, could use after needing purification, cost for purification is very high, does not have use value.How being applied in industrial combustion by the methyl alcohol of other purity except smart alcohol, and solving the not enough problem of burning, is an industrial at present important technology research direction.
Summary of the invention
The object of the present invention is to provide methyl alcohol heating plant, be intended to solve methyl alcohol cost in the application of industrial combustion in prior art higher, combustion heat supplying is not enough, and the problem of contaminated environment.
The present invention realizes like this, methyl alcohol heating plant, comprise for store and export methyl alcohol storage device, for by the gasification installation of methanol gasifying and the burner being used for gas heating, be communicated with successively by total pipeline between described storage device, gasification installation and burner, the methyl alcohol after described gasification installation comprises the retort for reacting gasification of methanol and utilizes the described retort gasification of burning is the thermocirculator of described retort heat supply.
Compared with prior art, the methyl alcohol heating plant in the present invention, its gasification installation can provide the special condition such as air pressure, temperature, the methanol gasifying containing impurity is become air mixture, is delivered to burner combustion heat supplying.Be air mixture due to what burn in burner, be relatively atomized methyl alcohol, its burning degree is high, formaldehyde can not be produced, and impurity in methyl alcohol organic matters such as () various alcohol, water together gasification, and combustion, fuel is not limited only to smart alcohol, the lower thick alcohol of use cost, useless alcohol can do fuel.
