Description
Technical field：
The present invention relates to the technical fields of Treatment of Sludge, are specifically related to a kind of charging gear of sludge drying.
Background technology：
With the continuous improvement of people's quality of life, the requirement of municipal sewage treatment also accordingly improves, municipal treatment plants
Load increases increasingly.The sludge volume that sewage treatment plant generates accounts for 0.3%~0.5% or so of processing water volume, one big
Type sewage treatment plant will generate the hundreds of even sludge of a few kiloton daily.According to statistics, the annual sludge (moisture content 80%) in the whole nation
Total output will break through 30,000,000 tons quickly.The features such as strong pollution, big quantum of output, high-moisture percentage, makes sludge treatment problem become
It is very intractable.Double attribute based on sludge itself --- pollutant and resource, recycling sludge include mainly the energy using technology
Change utilization, land use, building materials utilize, and these premises applied using technology are all sludge dryings.Sludge dewatering is dry
Changing also becomes the bottlenecks increasingly highlighted, and how to realize to low-carbon sludge drying also becomes a realization sludge therewith
The critical issue of recycling.
Drying sludge is the process of an energy net disbursement, and energy charge is used in a standard drying system and accounts for operating cost
Ratio be more than 80%.Therefore Treatment of Sludge belongs to highly energy-consuming trade, and the energy is the important substance basis of national economy, it is straight
It connects and influences national security, sustainable development and social stability.Energy consumption, enhanced heat exchange, raising are reduced in sludge handling process
The utilization rate of energy has become main problem, has not only alleviated financial burden of the country to Treatment of Sludge, but also to energy in sludge
The recycling of amount has positive impetus, development prospect wide.
Fume waste heat is one kind of boiler exhaust gas loss, and the presence of flue gas loss not only leverages boiler to fuel
Effective rate of utilization, and be discharged into the flue gas in air and also seriously compromise air quality, prodigious dirt is caused to environment
Therefore dye recycles fume afterheat and is also provided for the circular economy of power plant while meeting energy-saving and emission-reduction themes of the times
One practical way.
In existing sludge drying charging gear, the moisture content of wet mud is high, is fed into after desiccation apparatus by wet mud,
Since wet mud itself contains more moisture, cause sludge drying time in desiccation desiccation case long and drying efficiency reduction,
And current charging gear leads to the sludge excess load in desiccation case, also reduces once by sludge all feed desiccation apparatus
Drying efficiency, because the invention one kind just carrying out preheating and preliminary desiccation when sludge is fed to sludge and can adjust feed progress
Charging gear be very it is necessary to.
Invention content：
The purpose of the present invention aims to solve the problem that problem of the existing technology, provide one kind when sludge is fed can to sludge into
Row preheating and preliminary desiccation, and the charging gear of the sludge drying of energy conditioning of mud feed progress.
The present invention relates to a kind of charging gears of sludge drying, including feed hopper, sludge preheating mechanism, feed pipe and charging
Regulating mechanism；
Osculum is opened in the upper end Kai great Kou of the feed hopper, lower end；

In, one end of the flue gas outlet pipe is connected to the outlet of indirect dryer, the other end is pierced by the lower end osculum of feed hopper and passes through
The circulating-heating pump is connected on the flue gas inlet pipe on the big mouth in upper end of feed hopper；
Feed opening is formed on the feed pipe, the lower end osculum of feed hopper is arranged in the feed opening, the charging
Regulating mechanism includes the adjusting gas that the adjusting block for being fixedly connected on feed pipe lower end, piston shaft are fixedly connected with the adjusting block
The middle part lower section of cylinder, the feed pipe is equipped with support base, is hinged on the support base in the middle part of the bottom of feed pipe.
Spiral lamination from top to bottom is formed on the inner wall of the feed hopper, is equipped in feed hopper several for stirring sludge
Blender, the quantity of the blender is three, and the line of three blenders forms a triangle and will do indirectly
In dry device is enclosed in.
By above-mentioned technical proposal, in the use of the present invention, will wait for that the wet mud of desiccation is poured into feed hopper first, sludge
From the upper end of feed hopper, big mouth enters in feed hopper, and enters in feed pipe from the lower end osculum of feed hopper；At the same time, hot cigarette
Gas enters from the flue gas inlet pipe of sludge preheating mechanism in indirect dryer, carries out preheating to the sludge in feed hopper and tentatively does
Change, indirect dryer is discharged by flue gas outlet pipe in cooled flue gas later, and by being returned again after the heating of circulating-heating pump
Into flue gas inlet pipe, a flue gas recirculation is consequently formed, preheating and preliminary desiccation constantly are carried out to the sludge in feed hopper；It is first
The sludge of step desiccation enters from the lower end osculum of feed hopper in feed pipe, then out of, drying equipment after feed pipe entrance, this
During one, if the sludge quantity saturation in drying equipment, feed pipe and drying equipment are adjusted by feeding adjustment mechanism
Angle is fed, specifically, the piston rod for adjusting cylinder is shunk, and one end of adjusting block and feed pipe is driven to move down, otherwise feed pipe
Feed end increase, the speed that sludge enters drying equipment can be slowed down in this way, if sludge quantity in drying equipment is insufficient, adjusted
The piston rod of cylinder stretches, and drives one end uplink of adjusting block and feed pipe, otherwise the feed end of feed pipe is towards drying equipment
It tilts, the speed that sludge enters drying equipment can be accelerated in this way, the tune of progress is fed to realize feeding adjustment mechanism to sludge
Section.
In said program, the support base can be supported feed pipe, and feeding adjustment mechanism is enable effectively to adjust charging
The feed progress of pipe, the spiral lamination flow out in being exported from lower end with can guarantee sludge, and the blender can be to the stirring of sludge
It can accelerate the preliminary drying efficiency of sludge.
Through the above scheme, the sludge preheating mechanism of charging gear of the invention can carry out sludge when sludge is fed pre-
Hot and preliminary desiccation, feeding adjustment mechanism energy conditioning of mud is fed progress, to improve drying efficiency.
As a preference of the above scheme, one end of the flue gas inlet pipe connects boiler.
As a preference of the above scheme, the flue gas inlet pipe is equipped with flue gas recirculation blower fan.The circulating fan can
The flue gas recirculation in flue gas inlet pipe and flue gas outlet pipe is effectively ensured.
