Summary of the invention
The purpose of this utility model is to provide a kind of integrated apparatus that purifies the high humility dusty gas, integrates heater, bag-type dusting function, reduces the humidity of dusty gas, improves efficiency of dust collection, extends life of bag filter.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of integrated apparatus that purifies the high humility dusty gas, comprise heating tube group, filter bag group, gas-flow deflector, pulse spraying equipment, form ash-valve and housing, heating tube group and filter bag group front and back in housing are arranged, between heating tube group and filter bag group, be provided with gas-flow deflector, pulse spraying equipment is located at top, the corresponding heating tube group of difference and the filter bag group of housing, and the form ash-valve is located at the bottom of shell;
Described heating tube group is comprised of the tube bank be arranged in parallel, interbank by link of boards;
The bottom of described gas-flow deflector is provided with baffle maze, and baffle maze consists of the baffle plate of many channel-sections, and adjacent baffle plate notch side set interlock in opposite directions forms the gap that flue gas passes through.
Described housing is provided with heater and heat-insulation layer outward.
Compared with prior art, the beneficial effects of the utility model are:
Thoroughly solved the high humility dusty gas and be difficult for the technical barrier purified, and can uniform air-flow, improve efficiency of dust collection, extension fixture service life, convenient for maintaining management, concrete advantage is described below:
1) structural shape of heating tube group and filter bag group integrated arrangement, both facilitated pipe arrangement, dwindled the occupation of land space, is beneficial to again repair and maintenance;
2) the heating tube group formerly, the filter bag group after structural shape enter cloth bag after making the high humility dusty gas effectively be dried and filter, " sticking with paste bag " phenomenon does not occur, be beneficial to the service life that extends filter bag;
The proper alignment mode of 3) restraining in the heating tube group is beneficial to airflow uniform distribution, has improved purification efficiency;
4) gas-flow deflector can well protect filter bag not directly washed away by air-flow, its underpart adopt baffle maze make dusty gas by the time pass through constantly impact, gyroscopic action, big dust particle sinks to the bottom ash-pit, thereby reduces dust load, extends the filter bag life cycle;
5) pulse spraying equipment carries out the periodicity jetting deashing to heating tube bundle and filter bag, guarantees the maximization of heating tube bundle heating surface (area) (HS and the high efficiency of filter bag purification efficiency;
6) adopt the dust system of discharging of form ash-valve well to guarantee the tightness of installing, suppress the secondary fly-up of dust;
7) heat tracing layer parcel housing, dewfall does not occur in assurance device inside, is beneficial to whole system and efficiently moves.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in more detail.
See Fig. 1, it is a kind of integrated apparatus example structure schematic diagram that purifies the high humility dusty gas of the utility model, comprise heating tube group 1, filter bag group 2, gas-flow deflector 3, pulse spraying equipment 4, form ash-valve 5 and housing 6, heating tube group 1 is arranged in the interior front and back of housing 6 with filter bag group 2, between heating tube group 1 and filter bag group 2, be provided with gas-flow deflector 3, pulse spraying equipment 4 is located at top, the corresponding heating tube group 1 of difference and the filter bag group 2 of housing 6, and form ash-valve 5 is located at the bottom of housing 6; Heating tube group 1 is comprised of the tube bank be arranged in parallel, interbank by link of boards; The top of heating tube group 1 is connected with high temperature steam pipe 8, and the below of heating tube group 1 is connected with condensate pipe 9, and condensate pipe 9 is provided with steam trap 10.
The bottom of gas-flow deflector 3 is provided with baffle maze 7, and baffle maze 7 consists of the baffle plate of many channel-sections, and adjacent baffle plate notch side set interlock in opposite directions forms the gap that flue gas passes through.Housing 6 is outer is provided with heating tube 11 and heat-insulation layer 12, guarantees that dewfall does not occur in whole device inside, is beneficial to device and efficiently moves.Heating tube 11 can pass into steam, also can adopt electrical heating wire.
A kind of integral method that purifies the high humility dusty gas of the utility model, be that heater and sack cleaner are combined into one, and first the high humility dusty gas heated, and then carry out the method for bag type filtering, and its specific implementation step is as follows:
1) the high humility dusty gas is not to blow to the heating tube group 1 of upper end, the thermal treatment zone higher than the flow vertical of 16m/s, the high-temperature steam that heating tube group 1 internal circulation is 100 ℃～130 ℃, heated gas moves from top to bottom along the gap between heating tube tube wall and heating tube;
2) between the thermal treatment zone and filter bag district, be provided with gas-flow deflector 3, by air-flow guiding below, be provided with baffle maze 7 in the bottom of gas-flow deflector 3, prevent that dusty gas from directly washing away filter bag;
3) dusty gas that is heated to above dew-point temperature is discharged and is entered the filter bag district by the lower end of heating tube group 1, with the rate of filtration higher than 1.6m/min not, pass through filter bag, dust is intercepted and captured by the filter bag surface, and clean gas is discharged by the outlet of filter bag upper end, realizes the purification of high humility dusty gas.
Heating tube group 1 is carrying out when high-temperature heating dries also to wet dirt gas, carrying out effectively uniform to wet dirt gas; be heated, uniform wet dirt gas later is under the guide effect of gas-flow deflector 3; by baffle maze 7, enter filter bag group 2 from the filter bag bottom; both play good protection filter bag and prevented the effect that air-flow directly washes away; reduce again dust load, extend the filter bag life cycle.
When the gas communication resistance was excessive, the dust of 4 pairs of heating tube groups 1 of unbalanced pulse blowing device and filter bag group 2 outer wall depositions carried out the high pressure blow smelting operation deashing, can guarantee the high efficiency of heating and clean-up effect.Form ash-valve 5 can continually be discharged the dust under depositing, and prevents the dust secondary fly-up, alleviates the filter bag load.
