Embodiment 1

[0070] Such as figure 1 As shown, this embodiment provides a high-concentration viscous solid waste treatment device with a heat exchange unit 11 inside, wherein the heat exchange unit 11 is a wear-resistant oil bath heat exchanger.

[0071] The device includes a dense phase reactor 1, feeding equipment 3, heat carrier feed channel 4, gas outlet 5, solid outlet 6, air chamber 10, distribution plate 21, primary air inlet 8, secondary air inlet 9 and slagging pipe 14; wherein, the feeding equipment 3 is arranged in the middle of the dense phase reactor 1, the heat carrier feed channel 4 is located at the top of the dense phase reactor 1 and extends into the dense phase reactor 1, and the gas outlet 5 is arranged at On the top of the dense phase reactor 1 and on the side opposite to the heat carrier feed channel (4), the solid outlet 6 is arranged in the middle of the dense phase reactor 1, the air chamber 10 is located at the bottom of the dense phase reactor 1, and the distribu...

Embodiment 2

[0081] This embodiment provides the treatment method of the high-concentration viscous solid waste treatment device described in Example 1. In this embodiment, bagasse is used as the high-viscosity solid waste, and the specific method is as follows:

[0082]The heat carrier particles enter the dense phase reactor 1 through the heat carrier feed channel 4, and at this time, the shut-off valve of the slag discharge pipe 14 of the dense phase reactor 1 is in a closed state to prevent the heat carrier particles from flowing out. Simultaneously, the fluidizing air is passed into the dense phase reactor 1 through the air chamber 10, so that the heat carrier particles are in the shape of bubbling bubbles, the temperature in the dense phase reactor 1 begins to rise, and the shut-off valve of the slag discharge pipe 14 is opened to make the Cold ash flows out of the shut-off valve. When the temperature of the heat carrier particles rises to 500°C, close the shut-off valve of the slag d...

Embodiment 3

[0085] Such as Figure 4 As shown, this embodiment provides a high-concentration viscous solid waste treatment device with a heat exchange unit 11 inside, wherein the heat exchange unit 11 is a gas phase heat exchanger.

[0086] In this embodiment, the structure of the high-concentration viscous solid waste treatment device is the same as that of the device in embodiment 1 except that the gas phase heat exchanger is arranged in the gas phase.

[0087] The treatment method of the high-concentration viscous solid waste treatment device described in this embodiment is the same as that in Example 2.

[0088] Through the treatment method described in this embodiment, the material thermal conversion efficiency can reach 95%, the CO concentration in the discharged flue gas is far lower than the national standard requirement, and the energy conversion efficiency can reach more than 95%.

Abstract

The invention provides a sticky solid waste treatment device and a treatment method and use thereof. The device comprises a dense phase reactor, feeding equipment, heat carrier feeding channels, gas outlets, a solid outlet, air chambers, a distributing plate, a primary air inlet, a secondary air inlet and a deslagging pipe, wherein the feeding equipment is arranged in the middle of the dense phase reactor, the heat carrier feeding channels are positioned on the top of the dense phase reactor, the gas outlets are arranged on the top of the dense phase reactor, the solid outlets are formed in the middle of the dense phase reactor, the air chambers are positioned in the bottom of the dense phase reactor, and distributing plates positioned between the dense phase reactor and the air chambers connect the dense phase reactor and the air chambers. On the basis of the characteristic that the heat transfer speed of the heat carrier particles is fast and the heat conductive efficiency of the heat carrier particles is higher than that of gas or a liquid, in a heat conducting process, solid wastes can be quickly ground through grinding action among particle frictional groups, so that the problem that highly sticky solid wastes are hard to treat is further solved.

Description

technical field [0001] The invention belongs to the field of energy utilization, and relates to a viscous solid waste treatment device and its treatment method and application, in particular to a device for grinding high-viscosity solid waste by using the turbulence of high-concentration heat carrier particles and its Processing methods and uses. Background technique [0002] With the development of my country's industry, especially the processing and manufacturing industries that mainly process raw materials, a large amount of solid waste will be generated in the process of production and processing. disposal. [0003] For example, the furfural slag produced in the furfural production process has a high water content and acid content, which will seriously affect the combustion efficiency during the combustion treatment process, but deep dehydration of furfural slag has high energy consumption and waste water treatment. Difficulties and high costs of organic wastewater trea...
