Abstract

The utility model relates to a floated bagasse drying machine, and the bottom of a floated dryer is communicated with the middle-upper part of an ash storehouse arranged at the tail of a boiler through a draught fan. Flue gas with a certain temperature is extracted from the middle-upper part of the ash storehouse at the tail of the boiler through the draught fan, which enters the floated dryer after solid matters of dust, and the like in smoke gas are separated and eliminated through a one-time cyclone separating device, and because of the blowing force of the hot wind in the dryer, added bagasse is in the state of suspending. The bagasse and the smoke gas mix fully, which volatilize to eliminate a great deal of water, and the mixture of the bagasse and the smoke gas after drying is separated through a quadric cyclone separating device. The smoke gas returns to a dust-removal system, and the bagasse returns to a bagasse elevating machine to be sent to a boiler to be used as fuel. Under regular production situation, the bagasse water through drying reduces to 30% to 35% from about 48%, and the drying effect is evident. The furnace temperature of the boiler is improved, thereby improving the combustion efficiency of the boiler and saving a great deal of fuel, and the floated bagasse drying machine is beneficial to energy-saving and cost-reducing.

Description

Floated bagasse drying device

Technical field

The utility model relates to a kind of drying device, especially a kind of bagasse drying device that is used for dry bagasse and other solid-phase material.

Background technology

Bagasse in the production process of sugar refinery, the overwhelming majority is used as the boiler oil burning, bagasse moisture content is generally about 48%, directly enter the boiler internal combustion, just can reach the ignition point of bagasse after moisture also needs to evaporate greatly in boiler furnace, influence the fire box temperature of boiler, reduced boiler efficiency.Some bagasse is imperfect combustion just to be taken out of outside the stove, has not only wasted fuel greatly, also can influence the production and the ecological environment of sucrose.Therefore, the bagasse in the production process of sugar refinery should carry out earlier re-using after drying is handled, though various equipment to the bagasse drying are a lot of at present, utilizes the device of the floated dry bagasse of boiler smoke also not find at home to use.

The utility model content

The purpose of this utility model is to propose a kind of floated bagasse drying device, extract the flue gas that uniform temperature is arranged from boiler tail Hui Cang middle and upper part by air-introduced machine, enter floated drier after separating the solid matters of removing in the flue gas such as dust by cyclone separator, in drier owing to be subjected to the power of blowing of hot blast, the bagasse that adds is in suspended state, bagasse fully mixes with flue gas, a large amount of moisture content are removed in volatilization, dried bagasse separates by the secondary cyclone separator with smoke mixture, flue gas is got back to dust pelletizing system, bagasse is got back to bagasse rising machine, sends into boiler as fuel.Under the ordinary production situation, be reduced to 30%-35% by dried bagasse moisture content from about 48%, obvious drying effect has improved boiler hearth temperature, thereby has improved boiler combustion efficiency, has saved a large amount of fuel, helps saving energy and reduce the cost.

The utility model is achieved in that a kind of floated bagasse drying device, air-introduced machine, floated drier, cyclone separator are arranged, it is characterized in that: floated drier bottom is communicated with by air-introduced machine with the Hui Cang middle and upper part that is positioned at boiler tail, respectively there are band the going out of supervising device, charging aperture in floated drier upper and lower part, and the discharging opening on floated drier top is communicated with a cyclone separator that separates bagasse and smoke mixture.

The entrance and exit of described air-introduced machine is respectively installed arrangements for speed regulation.

The inlet of described air-introduced machine links to each other with the Hui Cang middle and upper part of boiler tail by a cyclone separator, and the outlet of blower fan is communicated with floated drier bottom.

The discharging opening of described floated drier connects the secondary cyclone separator, and secondary cyclone separator back is No. three cyclone separators and then.There is the rising machine of a conveying bagasse discharging opening below of secondary cyclone separator and No. three cyclone separator bottoms.

The drying device that the utility model proposes extracts the hot blast position to be determined in boiler tail Hui Cang middle and upper part, in case the bulky grain solid matter enters in the drying system equipment is caused damage; Hot blast enters air-introduced machine after extracting from boiler tail Hui Cang middle and upper part again after cyclonic separation is removed solid matter, bagasse in drier owing to be subjected to the hot blast effect to be in suspended state.Focus on controlling the interior bagasse amount of floated drier and the balance of hot blast, make bagasse be in suspended state at any time, in air-introduced machine and inlet, outlet arrangements for speed regulation are installed, in drier and go out, feeding mouth installs supervising device, to guarantee the normal operation of whole drying system.
