Description
Technical field
It is specifically a kind of dirty for removing heat-mass exchange equipment and pipeline outer wall the present invention relates to caloic exchange system field
The On Line Foul Removing Technology device of dirt.
Background technique
In recent years, with the rapid development of social economy with the continuous growth of the size of population, in addition the scarcity of natural resources,
Energy conservation is increasingly valued by people.Such as answering for high heat efficient boiler, consumer waste incineration or biomass power generation by waste combustion technology
With etc. be gradually applied.
In these energy utilization technologies, heat-mass exchange equipment is common using energy source equipment.When equipment works, material
High-temp combustion in a device improves energy utilization efficiency, usually in high-temperature flue gas for the heat in the flue gas of reclaimer discharge
Multiple rows of exhaust-heat absorption coil pipe is set in the channel of circulation, is full of cryogen in coil pipe, passes through power device and external container shape
At circulation loop to absorb the heat in flue gas.Because containing a large amount of pollutants such as dirt oil, flying dust in flue gas, exchange heat when passing through
When coil pipe, the dirts such as a large amount of dirt oil and flying dusts, which are just attached on coil pipe pipeline, forms dirt such as dirt block, due to coil pipe tube wall
Between be fitted into it is close, it is not easily to fall off, easily cause the blocking in mixed gas pipeline road.Therefore scale removal problem is always this field skill
Art personnel's urgent problem.
Currently, common descaling method has 1, artificial scale removal, 2, high-pressure hydraulic scale removal, 3, chemical cleaning, 4, steam blowing
Scale removal, 5, air distribution combustion detonation, 6, the methods of expand with heat and contract with cold.Method 1 behind coil pipe back and convection heating surface to can not remove
Completely, it is difficult to which clear all dirt；Method 2 is due to using high-pressure hydraulic pump, and energy consumption is high, only blows siphunculus journey, cannot thoroughly remove
Tube wall dirt；Chemical addition agent usage amount is big in method 3, at high cost, it is desirable that channel temperature reaches 1200 DEG C or so, it is necessary to use
Special chemicals dosing plant, and it is difficult to ensure that dispensing is uniform when dosing；The energy consumption of method 4,5 is big, scale removal is not clean, and needs frequent
It cuts heat exchanger purging and burning, labor intensity of workers is big；Using cold oil and hot oil, alternately switching reaches scale removal purpose to method 6, right
Heat-mass exchange equipment service life has a significant impact, and is easy that equipment is made to generate leakage, and it is larger to implement difficulty.Make a general survey of with
Upper six kinds of methods, common feature are scale removal low efficiencys, and energy consumption is high, and most scale removal method must first arrestment system
Operation, could scale removal after exhaust gas channel and the decline of heat exchange coil temperature.
The object of the present invention is to provide a kind of On Line Foul Removing Technology devices for summary of the invention, are set with solving the exchange of prior art caloic
Existing for standby scale removal method can not On Line Foul Removing Technology the problem of.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of On Line Foul Removing Technology device, it is characterised in that: including parallel communication to the descaling material of smoke conveying duct bottom
