Embodiment 1

[0037] refer to figure 1 , the present invention provides a high-dryness sludge pipe-type steam jet slurrying device, which includes a pipe body 5, preferably the length of the pipe body 5 is greater than 300 mm, and the limitation of the length of the pipe body 5 in this embodiment is beneficial to make the pipe body 5 The sludge in the main body is more fully mixed with steam and brewing water. Of course, the size of the pipe main body 5 is not limited to the above, and can also be adjusted according to specific conditions.

[0038] In this embodiment, the pipe body 5 is a conical pipe. This structure is constricted from the inlet of the high-dryness sludge to the outlet of the pulped sludge, which "impedes" the flow of the sludge to a certain extent, and increases the interaction between the sludge and the steam and conditioning. The mixing effect of high-quality water, of course, the specific structural form of the pipe body 5 is not limited to the above, and can also be a...

Embodiment 2

[0049] refer to figure 2 , this embodiment is a modification made on the basis of Embodiment 1.

[0050] In this embodiment, the pipe body 5 is a straight pipe, and the high-dryness sludge inlet 1 and the pulped sludge outlet 7 are respectively arranged on both ends of the pipe body 5, such as figure 2 shown in .

[0051] In this embodiment, one or more conditioning water nozzles are arranged at the throat 102 where the high-dryness sludge inlet 1 is connected to the pipe body 5; one or more steam nozzles 4 are arranged on the side wall of the pipe body 5 , and distributed along the length direction of the pipe body 5, so as to fully mix and preheat the steam and the sludge in the pipe body 5.

[0052] In this embodiment, other structural forms of the high-dryness sludge tube-type steam jet slurrying device can refer to the description in Embodiment 1, and will not be repeated here.

Embodiment 3

[0054] The present invention also provides a high-dryness sludge tubular steam jet slurrying method, which adopts the high-dryness sludge tubular steam jet slurrying device described in Embodiment 1 or Example 2;

[0055] Specifically include the following steps:

[0056] (1) The high-dryness sludge is transported to the high-dryness sludge inlet, and after being cut by the mesh plate arranged at the high-dryness sludge inlet, several thin strips of sludge are formed and enter the pipe body;

[0057] (2) Turn on the conditioning water nozzle and the steam nozzle, so that the conditioning water and steam are sprayed into the pipe body at high speed, and the high-speed impact force of the conditioning water and steam is used to destroy the original sludge structure, so that the conditioning water, steam and The sludge is vigorously and fully mixed in the pipe body to form a slurry sludge mixture, which improves the fluidity of the sludge, preheats the sludge at the same time, an...

Abstract

The invention provides a high-dryness sludge tube type vapor ejection pulpifying device and a method. The high-dryness sludge tube type vapor ejection pulpifying device comprises a tube body, wherein a high-dryness sludge inlet and a pulpified sludge outlet are formed in the tube body; one or more hardening and tempering water nozzles are arranged at the high-dryness sludge inlet; the hardening and tempering water nozzles are used for ejecting hardening and tempering water into the high-dryness sludge inlet at high speeds; one or more vapor nozzles are arranged on the tube body; the vapor nozzles are used for ejecting vapor into the tube body at high speeds; high-dryness sludge is fed into the tube body from the high-dryness sludge inlet and is violently mixed with the hardening and tempering water and the vapor which are ejected in at the high speeds to form a pulpified sludge mixture which is discharged out from the pulpified sludge outlet. The invention provides the high-dryness sludge tube type vapor ejection pulpifying device and the method which are capable of effectively achieving pulpification of the high-dryness sludge, are high in heat exchange efficiency, simple in structure, small in floor space and low in investment cost, and can be widely applied to the field of organic biomass pretreatment of cities.

Description

technical field [0001] The invention relates to the technical field of urban sludge pretreatment design, in particular to a high-dryness sludge pipe-type steam jet slurrying device and method. Background technique [0002] Existing sludge mixing systems, such as the utility model patent No. 200720069024.8, disclose a kind of sludge and garbage mixing solidification system, including a mixing tank, a material inlet, a material outlet, and a number of stirring shafts are arranged in the mixing tank. A plurality of stirring arms are fixed on the stirring shaft, at least one stirring blade is arranged at the front end of each stirring arm, and side blades having the same number as the stirring blades are arranged at the rear end of each stirring arm. [0003] This kind of sludge and garbage mixed solidification system, that is, the sludge mixing system, uses the motor to drive the stirring shaft to stir the sludge. Because the quality of high-dry sludge is relatively poor, the v...
