Problems solved by technology

The organic matter in the sludge is about 50%, and the calorific value of the dry mixed sludge is 24-29MJ / kg. Theoretically, the calorific value held by itself can only be burned when the water content is lower than 70%. Moisture is a better fuel and can generate sufficient heat; however, existing sludge drying or incineration equipment such as rotary kiln, rotary furnace, spouted bed, etc., due to the high water content, high viscosity and solidification of sludge Severe fouling characteristics, low efficiency of equipment, because of large volume, heavy equipment is not easy to move; complex process, high investment, and need to remove a lot of water to be used as raw materials for treatment, and the sludge dust that is inevitably generated during the drying process easy to explode
In the published technical data of the chain-type drying and pyrolysis oil production device and system, only the application numbers 2006101597443, 2006101597443, The technical scheme disclosed in the application number 2006101597439 of "Biomass, especially activated sludge chain-type drying and pyrolysis equipment and system", this scheme has a small biomass treatment capacity per unit time, if flow The operation of the technical scheme of the chemical bed heating furnace is relatively difficult to grasp when the processing scale is relatively small, and the structure is relatively complicated; in addition, there are still many places to be further improved and supplemented in the structure and technical scheme of the device, and we have not yet seen the chain of the present invention. Heat transfer between road walls, radiation and oxygen-deficient or even anaerobic frying water to produce sustainable control of weak frying and pan-frying and candle heat transfer principle for drying, incineration, pyrolysis gas or oil production equipment and other systems to report

Embodiment 5

[0076] in Picture 10 In, the present invention is shown as Example 5 with drying as the main and pyrolysis as the supplement;

[0077] The feature of this embodiment is that three pairs of chain heat exchangers 23A, 23B, and 23E are arranged in the housing 2. The two groups of chain heat exchangers form two pairs of symmetrically inclined chain heat exchangers 23A and 23B. The two sets of chain heat exchangers form a pair of symmetrical chain heat exchangers 23E; the two up-chain channels 10 of the pair of symmetrical chain heat exchangers 23E are respectively arranged in the partition screen 8 and the chain heat exchange with their own chain cables In the drying channel 40 formed by the heating vertical walls 38a of the heaters (23B and 23A); the top wall of the drying channel 40 is provided with a fluid fuel burner 39, and the high-temperature gas generated by the burner 39 passes through the drying channel 40 and passes through the lower end of the turning The chain channel 1...

Embodiment 7

[0080] in Picture 9 with 15 In, the present invention is shown as Example 7 with drying as the main and pyrolysis as the supplement;

[0081] The heat generation subsystem adopts a rotating grate fluidized bed heating furnace, and the fluidization medium is air; on the basis of Example 8, a series of hoods 31 are uniformly arranged on the plane of the rotating grate turntable 104 to replace the vent slits. 31 is a rectangular hollow blind tube, a series of air jet holes are uniformly arranged on the dead end side of the upper part of the blind tube, and the cavity at the lower part of the blind tube is connected to the air distribution chamber 83.

[0082] Three groups of chain heat exchangers are installed in a constant temperature space, of which two groups of chain heat exchangers 23A and 23B form a pair of symmetrically inclined chain heat exchangers, and the other group of chain heat exchangers 23E has an upward chain 10 is set in the drying channel 40 formed by the heating v...

Embodiment 9

[0087] in Figure 19 In this, it shows the system of the present invention as a raw material for dehydration and drying of finished products, concurrent production of high-temperature gas supply, and auxiliary production of liquefied oil. It shows that the present invention is used as a drying and pyrolysis oil production system. Example 3 or 5 or 8 or 9 are combined into a system for obtaining liquefied bio-oil from activated sludge raw material biomass; adding sludge with a temperature of 15-25°C, a particle diameter of ≤3mm, and a water content of 50-65% The auger of the material subsystem is added to the inlet 5 of the moisture evaporation section of the down chain of the chain heat exchanger.
