Description

RTO accumulation of heat incinerator

Technical field

The utility model relates to industrial waste gas technical field, in particular to a kind of RTO accumulation of heat incinerator.

Background technique

For the VOCs treatment of large-wind-volume low-concentration, carried out usually using RTO (heat accumulating type oxidation furnace device) equipment Processing.The use of burner in existing RTO is relied on, burning slow with burning velocity is not thorough, burn dangerous, generation nitrogen Oxide causes heat storage to glue stifled phenomenon.

Therefore, how to design a kind of burning velocity is fast, burning thoroughly, combustion completion, the RTO for reducing discharged nitrous oxides store Thermal incinerator is current environmental protection cause urgent problem to be solved.

Utility model content

In order to solve the above technical problems, the utility model discloses a kind of novel RTO accumulation of heat incinerator, including cabinet (1), Burner (4), combustion chamber (5), heat storage (2), guide layer (3), blower (18), air inlet valve (6,9,12), outlet valve (7,10, 13), blow down valve (8,11,14), burner valve (15,16,17).The burner (4) is evenly spaced in cabinet by same distance (1) top provides heat for combustion chamber (5), and in the middle part of cabinet (1), guide layer is arranged in the bottom of box for heat storage (2) setting (3).The multiple valves of case Ligation in vitro, the burner valve (15,16,17), which is arranged above cabinet, connects cabinet and natural gas, The air inlet valve (6,9,12), outlet valve (7,10,13), blow down valve (8,11,14) setting below the cabinet (1) connection cabinet with Respective intake stack, wind pipe, purging pipeline, these valves are arranged according to system to automatically turn on or closes, and maintains system Operation.

As a further improvement of the foregoing solution, the burner (4) is evenly distributed on top of the box, is controlled by valve every The opening and closing of a burner makes regenerative chamber rationally transfer heat, and burner is only opened in corresponding regenerative chamber accumulation of heat, realizes resource Peak use rate.

As a further improvement of the foregoing solution, burner is selected as oxygen-enriched burner, and oxygen-enriched burner has accelerates Burning velocity promotes combustion completion, the ignition temperature for reducing fuel and reduction tail-off time, the reduction of nitrogen oxides yield etc. excellent Point is that the viscous stifled phenomenon occurrence probability of regenerative chamber reduces, extends service life of equipment.

As a further improvement of the foregoing solution, the regenerative chamber three is set, regenerative chamber functional areas be respectively heating zone, Heat release zone, purge zone.As system is run, the successively orderly rotation of each functional areas makes heat obtain an equitable breakdown.

As a further improvement of the foregoing solution, each regenerative chamber lower part be arranged three valves control respectively air inlet, outlet air, Purging.After three valves receive signal in system operation, closure or openness are carried out according to signal, reach one in regenerative chamber heat absorption When determining temperature, the outlet air valve of the regenerative chamber closes air inlet valve opening, the heat in the waste gas absorption regenerative chamber of entrance；Work as storage When hot cell heat release reaches certain temperature, air inlet valve closes purging valve opening, carries out reverse gas cleaning to heat storage；Work as regenerative chamber After the completion of middle deashing, purging valve is closed, and outlet air valve opening, heat storage starts to absorb heat.

For this structure on year-on-year basis with other RTO devices, burning velocity is fast, burns abundant enough, combustion completion coefficient height, then after The nitrogen oxides of synthesis is few, will not secondary pollution environment, it may also reduce heat storage glues stifled phenomenon.

(16) in the open state, other two burner valve (15,17) are in close state, and provide heat by the burner below burner valve 2. (16) when exhaust gas in heat storage by flowing out Carry out combustion reaction.Clean gas after burning enters the accumulation of heat of the leftmost side with amount of heat under air-suction duct suction Room, when flowing through heat storage, 1. (7) heat storage heat absorption, the gas after heat release enters discharge pipe by outlet air valve via after guide layer Road heel row goes out chimney.

The blower operating in pipeline is purged at this time, and blow down valve is 3. (14) in the open state, and air draught enters right side regenerative chamber Middle carry out reverse gas cleaning, cleaning particle, which likewise enters, carries out combustion reaction in combustion chamber, the gas being purified enters left side and stores Behind hot cell outside discharger.

For left side regenerative chamber after the heat for absorbing a period of time, regenerator temperature reaches saturation, system control valve door, left side 1. (7) outlet air valve in regenerative chamber is closed, 1. (6) air inlet valve is opened；Valve is entered the wind in intermediate regenerative chamber 2. (9) to close, Valve is purged 2. (11) to open；Right side regenerative chamber purges valve and 3. (14) closes, 3. (13) outlet air valve is opened.Corresponding combustion 1. (4) burner valve is opened, remaining burner valve is in close state.

Left side regenerative chamber is after releasing heat for a period of time, as the exhaust gas that the loss of heat cannot have been sucked just again provides Heat, system is converted again at this time, 1. (6) air inlet valve is closed, 1. (8) purging valve is opened；Intermediate regenerative chamber is blown It sweeps valve 2. (11) to close, 2. (10) outlet air valve is opened；3. (13) regenerative chamber outlet air valve in right side is closed, air inlet valve is 3. (12) it opens.Corresponding burner valve (17) is opened, remaining burner valve is in close state.

System after running for a period of time, continues the conversion that order occurs, by the conversion of every time, the heat of system Amount maximizes the use, and reduces energy waste.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
