Abstract
The utility model discloses a tail gas discharge device after the mud air flow becomes dry. The device consists essentially of an air discharge pipe (1), a soundproofing water discharge room (2) and a gas discharge outlet (3); wherein, the soundproofing water discharge room (2) is connected above the air discharge pipe (1) and the gas discharge outlet (3) is connected above the soundproofing water discharge room (2). The soundproofing water discharge room (2) is composed of a housing (21), an internal housing (22), a gas inlet pipe (23), a water delivery pipe (24) and a filling material room (25), wherein, the gas inlet pipe is arranged on the internal house (22), the water delivery pipe (24) is arranged on the housing (21), the filling material room (25) is positioned between the internal house (22) and the housing (21), and the filling materials (26) are positioned in the filling material room (25). The device is simply structured and easy to be realized; can conduct the disposal of the tail gas discharge in connection with the dry tail gas in the solid powder shape or fragile solid air flow. The utility model is particularly applied to the drying or firing of the mud air flow.
Description
Technical field
The utility model relates to a kind of device that discharges behind the dedusting, specifically is the gas emission device after the sewage gas fluidized drying is handled.
Background technology
Municipal sewage treatment is built up in each city, the whole nation and is put into operation; this has played positive role to the water pollution problems that prevents China; but the mud that forms in the sewage disposal process has brought environmental pollution again; therefore aspect the protection environment, the processing of municipal sludge is become a problem of needing solution badly again.The method of disposal of mud mainly contains soil utilization, landfill, burning, biochemical treatment and topples over and throw sea etc. at present.But the moisture percentage in sewage sludge height that in sewage disposal process, is produced, volume is big, and this brings great inconvenience for its transportation, final disposal and utilization, therefore must utilize the means of sludge dewatering, drying, and moisture is separated from mud.Practice both domestic and external shows, after traditional concentrated and shrink PROCESS FOR TREATMENT, the moisture content of mud is difficult to reach below 70%, and economic mechanical dehydration moisture content of the cake also is about 75%, this moment, the calorific value of mud was very low, also needed very big energy expenditure if adopt the means of burning to handle.So reach the deep dehydration of mud, comparatively Jing Ji method is exactly to use heated drying technology and equipment commonly used in the chemical industry operation.The airflow drying tube of mud and roller drying have all obtained actual application at present, and there has been patent (patent No. 99250619.0), the tail gas that can produce in the dry run need carry out dust removal process, cyclonic separation is generally adopted in dedusting, air-flow after the dedusting is if be discharged in the air, be easy to generate a large amount of noises, these noises cause second environmental pollution again easily; And moisture is higher in the discharge tail gas, and these moisture major parts are from the mud, therefore will have stink, peculiar smell even to environment, to the material that the mankind are harmful to, these materials also can cause the secondary pollution of air equally.
Summary of the invention
The utility model provides the gas emission device after a kind of sewage gas fluidized drying, the tail gas that produces at mud heated drying process has stink, peculiar smell, noise is excessive during exhaust, cause the situation of air, environmental pollution easily, the tail gas that produces in the mud heated drying process is implemented noise elimination, processed, realize the non-pollution discharge in the sludge handling process.
The technical scheme that the utility model adopted is as follows: the gas emission device after a kind of sewage gas fluidized drying, mainly form by evacuated tube, noise elimination drip chamber and exhaust outlet, the drip chamber of wherein eliminating the noise is connected the top of evacuated tube, and exhaust outlet is connected the top of noise elimination drip chamber; Described noise elimination drip chamber comprises shell, inner casing, air inlet, drain port and filler chamber, and wherein air inlet pipe is installed on the inner casing, and drain pipe is installed on the shell, and the space between inner casing and the shell is a filler chamber, is placed with filler in the filler chamber.
Filler in the described filler chamber can be one or more mixing in little haydite, bead and the stainless steel steel ball.
Characteristics of the present utility model are: simple in structure, be easy to realize; Can be at solid powdery or the easily pneumatic conveying drying exhaust emissions processing of crushed solid, be specially adapted to sewage gas fluidized drying or burning, the mud of indication comprises city sewage and sludge, river course and lake dredging up mud, this type of mud granule is tiny, promptly loses flowability in higher moisture content interval and is thick solid matter.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1. evacuated tube among the figure, 2. noise elimination drip chamber, 21. shells, 22. inner casings, 23. air inlet pipe, 24 drain pipes, 25 filler chamber, 26. fillers, 3. exhaust outlet.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Figure 1 shows that a preferred embodiment of the present utility model.As shown in the figure, this device mainly is made up of evacuated tube 1, noise elimination drip chamber 2 and exhaust outlet 3, and the drip chamber 2 of wherein eliminating the noise is connected the top of evacuated tube 1, and exhaust outlet 3 is connected the top of noise elimination drip chamber 2.Noise elimination drip chamber 2 comprises shell 21, inner casing 22, air inlet pipe 23, drain pipe 24 and filler chamber 25, and air inlet pipe is installed on the inner casing, and drain pipe 24 is installed on the shell 21, and the space between inner casing 22 and the shell 21 is a filler chamber 25, is placed with filler 26 in the filler chamber.Filler 26 adopts little haydite, bead and stainless steel steel ball to mix.
Mud produces a large amount of tail gas through behind the heated drying.This part tail gas at first passes through technology dedustings such as cloth bag or whirlwind, tail gas after the dedusting still contains a large amount of moisture, and the flow of this air-flow is bigger, and flow velocity comparatively fast is easy to generate bigger noise, if the direct discharging of this part tail gas will be produced noise pollution, atmosphere pollution.After this part tail gas introduced this device, thus tail gas during by noise elimination drip chamber 2 volume amplify suddenly and slow down, reach the purpose of noise elimination in the time of deceleration; Tail gas enters in the filler chamber 25 by air inlet pipe 23 simultaneously, tail gas contacts with filler 26 surfaces and makes the temperature of tail gas reduce, condensate moisture in the temperature-fall period in the tail gas becomes liquid, condensed moisture is discharged under the effect of drain pipe 24, harmful, odorant in the tail gas discharged with the moisture that condensation goes out simultaneously,, directly discharge by offgas duct then reaching the standard of environmental protection through the tail gas after dehydration, the processing of eliminating the noise.
Claims (2)
1. the gas emission device after the sewage gas fluidized drying is characterized in that this device mainly is made up of evacuated tube, noise elimination drip chamber and exhaust outlet, and the drip chamber of wherein eliminating the noise is connected the top of evacuated tube, and exhaust outlet is connected the top of noise elimination drip chamber; Described noise elimination drip chamber comprises shell, inner casing, air inlet, drain port and filler chamber, and wherein air inlet pipe is installed on the inner casing, and drain pipe is installed on the shell, and the space between inner casing and the shell is a filler chamber, is placed with filler in the filler chamber.
