Abstract
The utility model discloses a tail gas burning furnace which comprises a cylindrical furnace body distributed axially and horizontally. A refractory material layer is arranged on the inner wall of the cylindrical furnace body; a tail gas inlet and an air inlet are formed at one end of the cylindrical furnace body, and a burnt gas outlet is formed at the other end of the cylindrical furnace body; and the cylindrical furnace body from the tail gas inlet to the burnt gas outlet comprises a primary furnace body, a secondary furnace body and a tertiary furnace body which are communicated in sequence. The furnace body of the burning furnace is divided into three levels, and the diameters and the lengths of the three levels are different, so that tail gas is convenient to sufficiently burn, and the conversion rate of burnt tail gas is improved.
Description
Technical field
The utility model relates to a kind for the treatment of apparatus of industrial sulphur-containing exhaust gas, relates in particular to a kind of combustion furnace that is used for exhaust combustion.
Background technology
In China's Energy Mix, coal accounts for 70%, and oil and natural gas accounts for 30%, and the chemical composition of coal is generally C, H, O, N, elements such as S, petroleum component are C, H, S, N, elements such as O, sulphur exists with the organic sulfur form in the crude oil, and the mass fraction of sulphur is generally 0.1%-7.0%, and natural gas consists of methane 85%, ethane 10%, propane 3%, other has a spot of H
2O, CO
2, N
2, He and H
2S.
Can produce a spot of SO after the above-mentioned fuel combustion
2Discharge atmosphere pollution with flue gas, adopt the high chimney emission can only diffusion dilution and chimney stack cost of investment height.Can be used for industrial fume desulphurization method at present and have tens kinds.Can be divided into absorption process, absorption method, catforming, burning purification, condensation cleaning, biological cleaning according to cleaning principle, also have advanced electron beam irradiation purifications, membrane separation process etc., but the ubiquity equipment investment big, problem such as how to take up an area of.
When adopting firing method, can use combustion furnace, mix then with air at the combustion furnace inner exhaust gas and burn, the problem such as the insufficient but existence of existing combustion furnace is burnt, a part of heat also runs off and causes waste.
The utility model content
The utility model provides a kind of combustion efficiency good tail-gas combustion stove, adopts multilevel hierarchy to improve the conversion ratio of element sulphur in the tail gas.
A kind of tail-gas combustion stove, comprise the tubular body of heater that axis horizontal is arranged, the inwall of tubular body of heater is provided with refractory masses, described tubular body of heater one end has tail gas and air intake, the other end is burning back gas vent, and the tubular body of heater is made of one-level body of heater, secondary body of heater and three grades of bodies of heater of being communicated with successively from gas inlet to burning back gas vent.
Described one-level body of heater, secondary body of heater and three grades of bodies of heater are 1: 3～4: 1.5～3 along the length ratio of tubular body of heater axis direction.
The diameter ratio of described one-level body of heater, secondary body of heater and three grades of bodies of heater is 1: 1.8～3: 1.2～1.6.
From roughly dimension scale as can be seen, the volume in the secondary body of heater helps the abundant burning of mist greater than one-level body of heater and three grades of bodies of heater.
The bottom of described secondary body of heater and three grades of bodies of heater is provided with some supporting legs, so that the installation of whole body of heater and firm.
Adopt the changeover portion of awl cartridge type to interconnect between the adjacent body of heater not at the same level.
The top of described three grades of bodies of heater is provided with two openings, is used for the gas after the part burning is discharged, and directly enters catalytic reactor.
Main sulfur-bearing composition is H in the pending sulfur-bearing tail gas
2S and SO
2, with after air mixes through one-level body of heater, secondary body of heater and three burnings of three grades of bodies of heater, make the H in the pending tail gas
2S is oxidized, and then changes next step operation over to.
In order to make full use of the heat release in the body of heater, heat exchanger is set in can be in body of heater, be the water of circulation in the heat exchanger, water heats up after absorbing heat, can be used for heating or heating.Heat exchanger can adopt shell and tube etc.
The body of heater of the utility model combustion furnace is three grades, and every grade diameter, length are all different, is convenient to the abundant burning of tail gas, has improved the conversion ratio of exhaust combustion.
