Description
Technical field
The utility model relates to catalytic combustion system, specifically can produce the catalytic combustion system of high-temperature hot air.
Background technology
When processing the organic exhaust gas of low concentration Wind Volume, people often utilize molecular sieve concentration runner to be concentrated by waste gas, thus waste gas is separated into two parts, part waste gas is not containing the pure air of organic solvent, this portion gas is directly emptying, a part is the air containing high levels of organic solvents in addition, and the air containing high levels of organic solvents utilizes catalytic combustion system to process further, and the oxidation in organic solvent in air is become after carbon dioxide and water again discharged to air.
Owing to needing temperature at the high temperature air of about 180 DEG C when molecular sieve concentration runner regenerates, and catalytic combustion carries out under the hot conditions of temperature about 300 DEG C, catalytic combustion is again the process of a release heat simultaneously, from the angle analysis that the energy makes full use of, the heat regeneration molecular sieve concentration runner utilizing catalytic combustion to produce is the selection that can realize economize energy.
Summary of the invention
The purpose of this utility model is the catalytic combustion system providing a kind of new structure, obtains the high temperature air that temperature is about 180 DEG C while organic solvent Catalytic Oxygen in waste gas is changed into carbon dioxide and water.
Above-mentioned purpose of the present utility model is achieved by the following technical programs:
The catalytic combustion system of high-temperature hot air can be produced, comprise be located at device bottom tubular heat exchanger, be located at the catalytic bed of side, device top and the plate-fin heat exchanger of top opposite side, catalytic bed is provided with air plenum chamber, connecting pipe is provided with between air plenum chamber and tubular heat exchanger, be provided with deflection plate in tubular heat exchanger, be communicated with by hot air outlet reducing between plate-fin heat exchanger with tubular heat exchanger.
Air containing organic solvent enters from tubular heat exchanger import, air plenum chamber is entered by pipeline, in catalytic bed, Catalytic Oxygen changes into carbon dioxide and water, high temperature air from catalytic bed air out, containing a large amount of heats, due to the stop of deflection plate, discharged to air after flowing to plate-fin heat exchanger from hot air outlet reducing after flowing through tubular heat exchanger in U-shaped mode, air to be heated obtains high temperature by plate-fin heat exchanger.
The utility model, by above-mentioned structural design, obtains the high temperature air that temperature is about 180 DEG C while organic solvent Catalytic Oxygen in waste gas is changed into carbon dioxide and water.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation in the utility model deflection plate A-A direction.
Detailed description of the invention
As shown in the figure, the utility model can produce the catalytic combustion system of high-temperature hot air, comprise be located at device bottom tubular heat exchanger 1, be located at the catalytic bed 8 of side, device top and the plate-fin heat exchanger 11 of top opposite side, catalytic bed 8 is provided with air plenum chamber 5, connecting pipe is provided with between air plenum chamber 5 and tubular heat exchanger 1, be provided with deflection plate 14 in tubular heat exchanger 1, be communicated with by hot air outlet reducing 13 between plate-fin heat exchanger 11 with tubular heat exchanger 1.
When catalytic combustion system normally works, air containing organic solvent enters tubular heat exchanger 1 from the import 2 of tubular heat exchanger 1, the air carrying out catalytic combustion process is needed to flow through in the heat-transfer pipe 15 of tubular heat exchanger 1 is managed, flow out from the outlet 3 of tubular heat exchanger 1 after being heated, air plenum chamber 5 is entered, then through catalytic bed 8 through air tube connector 4.In catalytic bed 8 catalyst effect under, in air, organic solvent is catalyzed is oxidized to carbon dioxide and water and releases heat.
High temperature air from catalytic bed 8 air out, containing a large amount of heats, the air of discharging from catalytic bed 8 (first flows through from the pipe of heat exchanger tube 15 according to vertical direction from the top down in U-shaped mode, by after the path 16 of deflection plate 14 bottom more from bottom to top vertical direction flow through from the pipe of heat exchanger tube 15) flow through tubular heat exchanger 1, the air heat simultaneously will flow through in the pipe from heat-transfer pipe 15.When the air of discharging from catalytic bed 8 flows through tubular heat exchanger 1 in U-shaped mode, air themperature progressively reduces, after finally flowing to plate-fin heat exchanger 11 from hot air outlet reducing 13, from the pure air floss hole 10 of plate-fin heat exchanger 11 discharged to air.
Needing the air of heating to enter plate-fin heat exchanger 11 from inlet of cold air 9, leave plate-fin heat exchanger 11 from by the outlet 12 of heating cold air, is exactly the high temperature air needing to obtain from the air of being discharged by the outlet 12 of heating cold air.
Air plenum chamber 5 is installed explosion-protection equipment 6 and air heating apparatus 7.The function of explosion-protection equipment 6 is time in catalytic bed 8, pressure is elevated to abnormal value, and explosion-protection equipment 6 is communicated with air automatically makes pressure in catalytic combustion system remain on safe range.
The function of air heating apparatus 7 is exactly utilize combustion of natural gas or diesel combustion or electrical heating to improve the temperature preparing to carry out catalytic combustion process air, and catalyticing combustion process is carried out continuously.
Air heating apparatus 7 also can be the heater of heat storage type.Do not allow that in some specific occasions naked light contacts with the air containing organic solvent, now, the way of safety be exactly utilize combustion of natural gas or diesel combustion or electric heater to heat in advance can the material of store heat, when the gas containing organic solvent is by heat accumulating, neat gas burner or diesel fuel burner or electric heater quit work, and the heat heating be stored in advance in heat accumulating needs to carry out the air of catalytic combustion process.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
