Abstract
The utility model relates to a four-in-one graphitic hydrochloric acid synthetic furnace. The utility model is respectively stacked by a gas synthesizing section, a cooling acid outlet section, a gas absorption section and a tail gas absorption section from up to bottom, wherein the cooling acid outlet section which is composed of a gas and liquid mixing chamber, a cooling section with an S-shaped cooling hole and an acid outlet section with a water interlayer is arranged between the gas synthesizing section and the gas absorption section. The absorption of reverse direction is realized. The flowing trend of the cooling water uses a sectional type, and the sections are communicated. The utility model integrates hydrochloric acid synthesis, absorption, cooling and tail gas treatment, and has the advantages of compact structure, small ground occupation area, simplification of process flow, enhancement of unit set yield and high product purity.
Description
Technical field
The utility model relates to a kind of hydrochloric acid synthesizer, especially relates to a kind of graphite hydrochloric acid synthesizer.
Background technology
At present, generally adopt the direct incendiary method of hydrogen and chlorine to produce hydrogen chloride gas in the world, in process of production, hydrogen and chlorine burning can be emitted a large amount of heats, cause the temperature of hydrogen chloride gas too high, need lower the temperature; In addition, always have a certain amount of water vapour in the synthetic hydrogen chloride gas, when temperature drops to the dew-point temperature of hydrogen chloride gas when following, hydrogen chloride gas will be combined into the hydrochloric acid of strong corrosion with water, and dew point corrosion has also just become urgent problem.Nineteen forty-two, the U.S. brings into use graphite to make the synthetic furnace of hydrogen chloride gas.Present hydrogen chloride gas synthetic furnace mainly contains following two kinds: a kind of be discharge the two-in-one synthetic furnace of hydrogen chloride gas temperature about 350 ℃, the temperature of the hydrogen chloride gas of its discharge is higher, can not directly use or advance the salt absorber acid, the middle need with a graphite cooler or graphite cooling tube road with gas cooling; The 2nd, can directly produce the three-in-one synthetic furnace of finished product hydrochloric acid, this synthetic furnace integrates burning, cooling, absorbs three kinds of functions, though part has overcome the shortcoming of two-in-one synthetic furnace, also need install the tail gas absorption equipment additional, has increased the cost of floor space and total system.
Summary of the invention
The purpose of this utility model provide a kind ofly collect that hydrochloric acid is synthetic, absorption, cooling, vent gas treatment be four unification graphite hydrochloric acid synthetic furnaces of one.
Technical solution of the present utility model is: a kind of four unification graphite hydrochloric acid synthetic furnaces, forms by gas synthesis stage, gas absorption section, cooling acid outlet section, tail gas absorber portion, it is characterized in that: the gas synthesis stage, cool off from bottom to top closed assembly successively of acid outlet section, gas absorption section, tail gas absorber portion.The cooling acid outlet section that the acid outlet section of the cooling section of gas-liquid mixed chamber, band S shape cooling hole and band water interlayer is formed is housed between gas synthesis stage and the gas absorption section, has realized reverse absorption.The tail gas absorber portion is to adopt the transition of band cavity graphite between packing tower and the gas absorption section.Water coolant moves towards to adopt sectional type, carries out between each section and gangs up.
The utility model collection hydrochloric acid is synthetic, absorption, cooling, vent gas treatment are one, and compact construction, floor space are little, can simplify technical process, improve separate unit output, the product purity height.
Description of drawings
Fig. 1 is four unification graphite hydrochloric acid synthetic furnace structural representations described in the utility model;
Fig. 2 is that four unification graphite hydrochloric acid synthetic furnace cooling acid outlet section structures described in the utility model and water coolant move towards figure.
Embodiment
Below in conjunction with accompanying drawing four unification graphite hydrochloric acid synthetic furnaces described in the utility model are described in further detail.
With reference to Fig. 1, water jacket 2 is arranged outside the gas synthesis stage 1, there is venting 12 gas synthesis stage 1 middle and upper part, gas synthesis stage 1 top connects cooling acid outlet section 3, connect gas absorption section 4 on the cooling acid outlet section 3, outside the cooling acid outlet section 3 cooling water jecket 5 is arranged, water jacket 2 is connected and the sealing of cooling acid outlet section 3 usefulness " O " type circle by flange with cooling water jecket 5, make water jacket 2 and cooling water jecket 5 separately, be provided with transition section 6 between gas absorption section 4 and the tail gas absorber portion 7, burner 8 is at the synthetic furnace foot, and gas synthesis stage 1 bottom has acid discharge mouth 14.Among Fig. 1,9,10 is the visor mouth, the 11st, and quick fire door, the 13rd, venting, 14,15,16 is hand hole, is convenient to change the filler of tail gas absorber portion 7,17,18,19,20 is the valve of different purposes.
With reference to Fig. 2, the water coolant trend of cooling in the acid outlet section 3 is: at first enter cavity 22 between graphite and the steel shell by entrance of cooling water valve 17, enter graphite cavity 24 by horizontal hand-hole 23 then, 25 get back to cavity 22 by laterally portalling again, to cocycle (shown in arrow among Fig. 2).Finished product hydrochloric acid after the absorption enters 26 backs, gas-liquid mixed chamber and enters back acid tank 28 by vertical hole 27, enters storage tank by going out an acid mouthful valve 21 at last.
Principle of work of the present utility model is: hydrogen, chlorine generates hydrogen chloride gas through burner 8 burnings, hydrogen chloride gas upwards flows along gas synthesis stage 1 inner chamber, mobile is passed to graphite tube with heat simultaneously, enter gas absorption section 4 through 3 distribution of cooling acid outlet section, with tail gas absorber portion 7, the pure absorption water of transition section 6 is finished most of the absorption in gas absorption section 4, most of heat is taken away by the middle part water coolant, remaining hydrogen chloride gas continues upwards to flow, enter tail gas absorber portion 7 and finish whole absorptions through transition section 6, the hydrochloric acid of generation downwards after 3 coolings of cooling acid outlet section the qualified high purity acid of output enter storage tank through valve 21.Be used for protecting the low-purity acid of this synthetic furnace base graphite often to discharge, avoid lamp holder is exerted an influence by acid discharge mouth 14.
The utility model four unification graphite hydrochloric acid synthetic furnace water coolant trends are: water coolant enters from the middle part through valve 17 earlier; upwards flow and flowed out by valve 18 in contact cooling acid outlet section 3 backs; enter once more through bottom valve 19 then; after valve 20 flow out; finish a circulation; middle part, bottom absorb water realizes ganging up for a short time at the cooling acid outlet section, protects cooling acid outlet section 3 graphite bodies with this, but does not influence the water coolant trend.
