Description

RTO heat accumulator anti-blocking structure

At present, with the rapid development of society, the problem of environmental pollution comes along. RTO is a high-efficiency organic waste gas treatment device. Compared with the traditional catalytic combustion and direct combustion type thermal oxidation furnace, the high-efficiency direct-fired thermal oxidation furnace has the characteristics of high thermal efficiency, low operation cost, capability of treating low-concentration waste gas with large air volume and the like, and can also carry out secondary waste heat recovery when the concentration is slightly high, thereby greatly reducing the production and operation cost. The principle is that organic waste gas is heated to over 760 ℃, so that VOC in the waste gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially-made ceramic heat accumulator to heat the ceramic body so as to store heat, and the heat is used for preheating subsequently entering organic waste gas, so that the fuel consumption of waste gas heating is saved. The ceramic heat storage chambers are divided into more than two, and each heat storage chamber sequentially undergoes heat storage, heat release, cleaning and other procedures, and works repeatedly and continuously. After the heat accumulation chamber is discharged, a proper amount of clean air is introduced to clean the heat accumulation chamber immediately, and the heat accumulation process can be started only after the heat accumulation chamber is cleaned. Otherwise, the residual VOCS are discharged to the stack with the flue gas, thereby reducing the treatment efficiency.

However, in the operation process of the existing system, the exhaust gas contains acidic ions such as organic Cl, Br, S and the like, meanwhile, ammonium groups such as triethylamine contained in the exhaust gas form ammonium salts after incineration, the ammonium salts are solid below 300 ℃, and are very easy to block a ceramic heat accumulator at low temperature, a special bulk heat accumulator is not designed for the same kind of products at present, and the solid ammonium salts directly remain at the bottom of the heat accumulator, so that the pressure loss of the system is increased, the treatment capacity is reduced, and the like.

After the condition that the heat accumulator blockked up appears, can satisfy whole RTO exhaust-gas treatment device's work needs only to change the heat accumulator totally, however, will lead to the cost of changing the heat accumulator very high like this, and need shut down for a long time, delay production.
