Abstract

The utility model provides a floating type sealed coke filtering device for a gasification furnace, which is composed of a furnace body and a furnace cover. The utility model is characterized in that the furnace body is provided with a water tank wit an outlet, and the furnace cover is placed inside the water tank in a floating type through a sealing ring on the furnace cover. The utility model can filter tar, dewater, and absorb smoke dust effectively and rapidly; the utility model can ensure sealing performance, shorten ignition time, improve combustion efficiency, simplify operation, balance furnace pressure, and improve the performances of safety and reliability in the process of stabilizing combustion; in addition, the utility model can eliminate pollution, recycle the tar, save cost, and enable the furnace body to have clean, sanitary, and beautiful appearance to adapt requirements of modern life.

Description

Floating type vapourizing furnace sealing tar filtering device

The utility model relates to a kind of sealing tar filtering device, especially a kind of floating type sealing tar filtering device that is exclusively used in biomass gasifying furnace.

Because it is fuel that biomass gasifying furnace can make full use of farming, woods waste such as tangerine bar, straw, bark etc., thoroughly solved the problem of countryside kitchen work power consumption, especially this vapourizing furnace can be saved the fuel more than 60%, and it is easy and simple to handle, the cooking is quick, sanitation and hygiene, thermal value height, therefore, be subjected to numerous rural subscribers' welcome deeply.But the body of heater of prior biological matter vapourizing furnace and bell seal by asbestos twine etc. mostly, and this sealing means one is that the filter of can not dewatering is burnt, makes part tar and water return burner hearth again and participates in burning, thereby influenced ignition time and combustion efficacy; The 2nd, can not use for a long time, otherwise body of heater and bell easily bond together by tar and be difficult to open, and in case open by force, then can tear asbestos cord to shreds and unrenewable, increased cost of use, part tar also can overflow the outer and influence cleaning, attractive in appearance of stove simultaneously; The 3rd, bell can not move with the variation of furnace pressure, easily causes the instability of operation, makes continuous firepower variation.Therefore, need improve existing biomass gasifying furnace and are perfect.

The purpose of this utility model is to overcome the deficiency of prior art, the draining of a kind of energy, filter Jiao is provided, and keeps body of heater exterior clean health, makes bell change the biomass gasifying furnace that fluctuates with furnace pressure and seals tar filtering device.

The technical solution of the utility model is: it is made of body of heater and bell, it is characterized in that body of heater is provided with the tank of taking mouth out of, and bell is by the unsteady tank that places of the sealing-ring on it.Described tank can be located at the body of heater upper end, is used for collecting, adsorbing moisture content, tar and the flue dust of flue gas, and the outlet on the tank is connected with tar well by pipeline, and the volume water of tar, flue dust, moisture content will be discharged and collection tar wherein so that will be mixed with.Sealing-ring on the described bell is provided with along the bell inner periphery, and form slick and sly drainage face with the bell inner-wall surface, so that moisture content in the flue gas and tar are gone in the tank along this wall flow, gas then can not outwards be overflowed, and plays the effect of sealing, by the sealing circle bell is floated in the tank simultaneously, both fixing bells, can make bell upper and lower unsteady again, reach the equalizing furnace internal pressure, safing effect with the variation of furnace pressure.Described bell can be made as two-layer at least, so that tar in the flue gas and moisture content can effectively be got rid of tar and moisture content in this condensation and flowing in the tank as early as possible, shortens ignition time, improves efficiency of combustion.

The utility model compared with prior art has following advantage and positively effect:

1, it can be effectively apace filtered tar, deviate from moisture content, absorb flue dust, improve sealing property, shorten ignition time, improve efficiency of combustion.

2, can realize automatic supply and discharging after in addition the water in the sealed cistern adds once, simplified operation, and make uncap very convenient, easily.

3, bell can change and upper and lower floating with furnace pressure, and balanced furnace pressure has also improved safety, unfailing performance in the stable burning process.

4, the tar after the filtration can be recycled once more, and expense has been saved in both decontaminations again, and tar can be not excessive, has kept cleaning, the health, attractive in appearance of body of heater appearance, adapts to the requirement of the modern life.

Fig. 1 is the structural representation of the utility model.

Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.

Among the figure, 1 is body of heater, is made of outer furnace shell 2 and inner furnace 3, be provided with insulation or packing material 4 therebetween, 5 is sealed cistern, is located at the body of heater upper end, fills water in the groove, the top of groove is provided with outlet 16, and link to each other with tar well 18 by connecting tube 17, when the water level in the groove was higher than outlet 16, the water of volume mouth thus discharged, and by collector recovery tar, 6 is free bearing, is connected with the handle 8 of uncapping by pin 7, is used to out, close bell, 9 is bell, be connected with handle 8 by

handle wrench axle

10,11 is outer bell, and 12 is the internal layer bell, on the bell inner periphery, be provided with sealing-ring 15, the sealing circle forms slick and sly drainage with the bell inner-wall surface and becomes 19, and sealing-ring 15 floats and places sealed cistern 5, and whole bell is floated, 13 for detecting the hole, which is provided with bolt 14.

Claims

1, a kind of floating type vapourizing furnace sealing tar filtering device is made of body of heater and bell, it is characterized in that body of heater is provided with the tank of taking mouth out of, and bell is by the unsteady tank that places of the sealing-ring on it.

2, sealing tar filtering device according to claim 1 is characterized in that the outlet that described tank can be located on the tank of body of heater upper end is connected with tar well by pipeline.

3, sealing tar filtering device according to claim 1 is characterized in that sealing-ring on the described bell along the setting of bell inner periphery, and forms slick and sly drainage face with the bell inner-wall surface.
