Abstract
The invention discloses a waste heat recovery system for the emptying tail gas treatment of a chemical device, which is characterized in that: the invention comprises a combustion chamber, a ring chamber, an ignition chamber, a steam generator and a water preheater orderly connected in series, wherein the ring chamber is connected with an emptying tail gas discharge pipeline for the chemical device, and the combustion chamber is connected with an air blower; the steam generator is provided with a steam drum, the steam drum is connected with the steam generator through one or over two sleeve pipe structures integrated with raising and declining by steam and water. The system has simple and reasonable structure and safe operation, saves energy sources, and realizes the purposes of the heat energy recovery of the chemical device and the reduction of tail gas discharge.
Description
Technical field
The present invention relates to vent gas treatment heat recovery technology field, be specifically related to a kind of chemical industry device emptying tail gas process heat-recovering system.
Background technology
In the prior art, the tail gas that some chemical plant installations (as the HCN device) produce directly has been discharged in the atmosphere, has not only polluted environment, but also has caused energy waste.At this present situation, some manufacturers have adopted exhaust treatment system or residual neat recovering system, but these system architecture complexity can not effectively reclaim the energy and less environmental pollution, and operational efficiency are low, exists potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is how a kind of chemical industry device emptying tail gas process heat-recovering system is provided, this system architecture advantages of simple, and security of operation is saved the energy, has realized the energy recovery of chemical plant installations and the target of minimizing exhaust emissions.
Technical problem proposed by the invention is to solve like this: a kind of chemical industry device emptying tail gas process heat-recovering system is provided, it is characterized in that: 1. comprise combustion chamber, ring cavity, calcination chamber, steam generator and water preheater, above-mentioned parts are serially connected in turn, wherein ring cavity connects chemical plant installations emptying end gas discharge tube, is connected with air-blaster on the combustion chamber; 2. described steam generator is provided with drum, and described drum is connected steam generator by the sleeve structure that steam more than one or two and liter waterborne decline unite two into one.
According to chemical industry device emptying tail gas process heat-recovering system provided by the present invention, it is characterized in that described drum can connect the outside thermic devices of using, and realizes heat recovery.
Beneficial effect of the present invention: 1, the thermal source of native system derives from the tail gas of the original emptying of chemical plant installations emptying, and this tail gas has been realized abundant burning through behind the native system, has reduced environmental pollution, has saved the energy; 2, the sleeve structure between drum and the waste heat recovery steam generator is the rise and fall of steam and the water structures that unite two into one, with the rising of routine, descending to separating is provided with very big difference, it is relatively simple for structure, can realize the rising of steam and the decline work of water in the sleeve pipe simultaneously; 3, in the chemical plant installations emptying end gas gas component all hydrogen be main, the concentration of hydrogen has very big-difference, is the burning of non-normal fuel, this system can guarantee that low hydrogen calorific value tail gas fully burns, and also can guarantee the safe combustion of high hydrogen tail gas (high heating value).
Description of drawings
Fig. 1 is a chemical industry device emptying tail gas process heat-recovering system of the present invention;
Wherein, 1, the combustion chamber, 2, the calcination chamber, 3, ring cavity, 4, the temperature distribution equalizing device, 5, steam generator, 6, drum, 7, sleeve structure, 8, water preheater.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, native system comprises combustion chamber 1, calcination chamber 2, ring cavity 3, parts such as steam generator 6 and the water preheater 9 formation series system that is serially connected, wherein combustion chamber 1 is connected with air-blaster, connect by ring cavity 3 between combustion chamber 1 and the calcination chamber 2, ring cavity 3 connects chemical plant installations emptying end gas discharge tube, ring cavity 3 inside are provided with the gas jet device, can make the tail gas multiple jets enter combustion chamber 1 and calcination chamber 3, fully mix with air, burning, be provided with the temperature distribution equalizing device in the calcination chamber 2, can quicken the abundant burning between air and the tail gas, improve mixed effect.Steam generator 5 is serially connected with calcination chamber 2, its top is provided with drum 6, wherein the sleeve structure 7 that unites two into one by some steam and liter waterborne, decline between steam generator 5 and the drum 6 is realized circulation, and drum 6 also can be connected in series external device (ED), realizes using and reclaiming of heat.Flue gas becomes low temperature and is extracted out through the chimney emptying by air-introduced machine after water preheater 8 further reclaims heat through behind the steam generator 5.
The present invention also can make various flexible frame mode in same area or association area, more than by the specific embodiment by the accompanying drawing illustrated embodiment, be to further describing that the foregoing of invention is made, but this should be interpreted as that the scope of the theme that the present invention is above-mentioned only limits to described example.Do not breaking away under the above-mentioned technological thought situation of the present invention, various replacements and change according to ordinary skill knowledge and customary means are made all should be included in protection scope of the present invention.
