Abstract
The utility model discloses a combined flue gas cooling device which comprises a flue gas passage, a fan, and a control apparatus, etc. The utility model is characterized in that a cold air pipe and a spray pipe with the bottom ends stretching into the flue gas passage are arranged on the side wall of the flue gas passage; the top end of the cold air pipe is connected with the fan; a cold air door controlled by the control apparatus is arranged in the cold air pipe; and a nozzle connected with a water tap and controlled by the control apparatus is arranged on the top end of the spray pipe. The utility model organically combines the spray cooling device and cold air mix cooling device and cools down the temperature of the flue gas while the temperature is rising, which keeps the temperature of the flue gas in a certain range to make a bag-type dust collector work with high efficiency. Therefore, the utility model has the advantages of low running cost and effective controlling of the amount of flue gas accumulation and moisture accumulation to a relatively best state.
Description
Technical field
The utility model relates to flue gas processing device, especially relates to a kind of combined flue gas cool-down device that cold wind combines with water spray of mixing.
Background technology
The flue gas of various kilns and boiler needs dedusting, because flue-gas temperature is too high, can bring difficulty to the operation than advanced sack cleaner at present, therefore need lower the temperature to flue gas.Traditional cold wind and spray cooling technology of mixing generally all distinguished separately and adopted.But adopt these two technology can bring corresponding negative effect separately: mix the cold wind cooling separately and can cause exhaust gas volumn to increase greatly, spray cooling can cause the flue gas water content to increase separately, and these all can carry out flue gas ash removal to sack cleaner and bring difficulty.
Summary of the invention
Thereby the purpose of this utility model be to provide a kind of with water injector with mix cooling air unit and organically combine, keep the constant combined flue gas cool-down device that makes the sack cleaner high-effective dust-removing of flue-gas temperature.
The purpose of this utility model is achieved in that the utility model comprises exhaust gases passes, blower fan, control device and temperature sensor, feature be the sidewall of exhaust gases passes be provided with the bottom stretch in the exhaust gases passes cooling air duct and the water spray conduit, the top of the cooling air duct machine of giving a dinner for a visitor from afar, in cooling air duct, be provided with the cold-air flap of controlled device control, be provided with the nozzle that connects running water pipe and the control of controlled device on the top of water spray conduit.
Cooling air duct and water spray conduit are the ring duct around exhaust gases passes, and cooling air duct is parallel to each other with the water spray conduit.
The utility model stretches into the cooling air duct in the exhaust gases passes and the conduit of spraying water owing to be provided with the bottom in exhaust gases passes, and cooling air duct and the control of all controlled device of water spray conduit are so just with the spray cooling device and mix cold-air temperature-reducing device and organically combine.At first with the working procedure input control device, temperature sensor is constantly passed to control device with data, when flue-gas temperature when constantly rising to the critical point of setting, control device at first starts mixes cold-air temperature-reducing device, open cold-air flap, blower fan is blown a cold wind in exhaust gases passes by cooling air duct, flue gas is lowered the temperature, at this moment exhaust gas volumn can constantly increase on the original basis, when exhaust gas volumn increased to the critical point of setting, control device was restarted the spray cooling device, and nozzle is sprayed water in exhaust gases passes, at this moment, these two kinds of heat sinks move simultaneously, and the exhaust gas volumn that makes these two kinds of heat sink operations cause increases and the water content increase is in an Optimal Control value, reaches best of breed, and keep flue-gas temperature constant in certain temperature range, for carrying out flue gas ash removal, sack cleaner creates convenience.After flue-gas temperature was reduced to design temperature, control device quit work these two kinds of heat sinks according to predefined program.Therefore also to have operating cost low and can be controlled at flue gas increase and moisture increase the advantage of relative optimum state effectively for the utility model.
