Description

Anti-clogging is blown row pipe flue gas evaporator

Technical field

The utility model belongs to coal-burning power plant's minimum discharge wet flue gas heating evaporation processing technology field.

Background technique

In recent years, with the implementation of stringenter environmental protection policy, it is desirable that coal-fired plant flue gas must reach minimum discharge mark Standard, wherein the wet flue gas of tail portion requires to eliminate white cigarette, avoids the formation of haze.Usually wet flue gas is introduced into original chimney So that it is discharged into higher space, complete dilution diffusion, but need to carry out preservative treatment to inner wall of stack, injects capital into more. It also takes at present and heating evaporation processing is carried out to wet flue gas to eliminate white cigarette, it is using power plant's hot water to outer around air inlet pipe Portion is heated, and the wet flue gas containing particulate matter is introduced into air inlet pipe, is discharged in atmosphere after heated evaporation by dry flue gas outlet. Because containing particulate matter, aerosol in wet flue gas, dirt impurity, easy crystalline material etc. can be blocked gradually in During Process of Long-term Operation Air inlet pipe can not clean dust, influence flue gas Channel Group, and can not dredge, ultimately cause and scrap, and shorten equipment uses the longevity Life, increases the financial burden of enterprise；On the other hand, air inlet is setting up and down with gas outlet, and position is increased, also not using installation It is enough convenient.

Utility model content

The purpose of the utility model is to provide one kind can periodically remove impurity, is not easy to plug, easy for installation, service life Longer anti-clogging is blown row pipe flue gas evaporator.

To achieve the goals above, the utility model include: shell, it is high-temperature medium inlet tube, high-temperature medium outlet, wet Flue gas inlet tube, dry flue gas outlet, left side plate, right end plate, tubulation, unloading valve, ash cellar, in shell lower bottom part, successively fixation is set It is equipped with unloading valve and ash cellar, is fixedly installed high-temperature medium inlet tube in shell left part, is fixedly installed high temperature in shell right part Media outlet pipe, is fixedly installed wet flue gas inlet tube in rear, is fixedly installed dry flue gas outlet in shell front, Several tubulations uniformly penetrate between left side plate and right end plate and intermediate inside housings, tubulation left end and high are laterally fixedly installed Warm medium inlet connection, tubulation right end are connected to high-temperature medium outlet, and upper end is provided with top blowing mouth inside housings, Top is fixedly installed top blowing inlet tube outside shell, and top is blown mouth and is connected with top blowing inlet tube, in shell Internal front-rear side walls are respectively arranged with side blowing mouth, are fixedly installed side blowing inlet tube, side spray in hull outside portion Blow gun is connected with side blowing inlet tube.

So when in use, it can be convenient the wet flue gas discharge that wet flue gas inlet tube is connected to power plant's minimum discharge tail portion Mouthful, dry flue gas outlet is connected to exhaust pipe or chimney, high-temperature medium inlet tube is connected with the hot water of power plant or vapour source, High-temperature medium outlet is connected to return line；Tubulation heating temperature is increased by hot water or steam, contains particulate matter, miscellaneous Object, crystalline solid wet smoke waste gas enter through wet flue gas inlet tube, from the gap between each tubulation outside to dry flue gas outlet Place's flowing, by tubulation heating evaporation while flowing, crystalline solid, aerosol etc. in flue gas are formed by evaporation to dry cigarette up to standard Gas, wherein the particulate matter to fall can be discharged into ash cellar by operating unloading valve.It works after a certain period of time, enclosure interior and tubulation When surface has dust stratification to influence work, it is clear to enclosure interior progress high pressure draught blowing that mouth and side blowing mouth are blown using top It sweeps, the dust of cleaning falls on lower part, is discharged into ash cellar by operating unloading valve, can effectively avoid internal blockage problem.High temperature Medium inlet, high-temperature medium outlet, dry flue gas outlet, wet flue gas inlet tube are fixed at shell left-right and front-back four In week, height is lower, is easily installed construction.With can periodically remove impurity, be not easy to plug, easy for installation, service life is longer The features such as.

Detailed description of the invention
