Two-section type direct-heating chain plate type thermal desorption system

Abstract

The invention discloses a two-stage direct-heating chain plate type thermal desorption system, which comprises a first desorption chamber and a second desorption chamber which are communicated with each other, wherein a first chain plate type crawler system and a second chain plate type crawler system are respectively mounted in the inner cavities of the first desorption chamber and the second desorption chamber, a first combustion system and a second combustion system which are positioned above the crawler systems are respectively mounted at the tops of the first desorption chamber and the second desorption chamber, a feeding hole and a flue gas outlet are formed in the front end of the first desorption chamber, a discharge hole is formed in the rear end of the second desorption chamber,the first chain plate type crawler system and the second chain plate type crawler system are installed in an up-down parallel lap joint mode, the tail end of the first chain plate type crawler systemis located above the front end of the second chain plate type crawler system, and ash removal openings are formed in the bottom of the first desorption chamber and the bottom of the second desorptionchamber. By adopting the two-section type direct-heating chain plate type thermal desorption system, continuous feeding and discharging of materials can be ensured, the treatment capacity and the treatment efficiency are greatly improved, and the two-section type direct-heating chain plate type thermal desorption system has the advantages of high heat source efficiency utilization, fast heat transfer, less dust production and the like.

Description

Technical field[0001]The invention relates to the technical field of contaminated soil remediation equipment, in particular to a two-stage direct thermal chain plate type thermal desorption system with super large processing capacity.Background technique[0002]At present, the development of thermal desorption technology at home and abroad has been quite mature, and an industrial chain of thermal desorption technology has been formed. Thermal desorption equipment can be divided into direct thermal desorption and indirect thermal desorption according to the heating method. Because direct thermal desorption has higher heat transfer efficiency than indirect thermal desorption, the processing capacity is also larger, and it has better application advantages in the market. . In actual engineering applications, the size of the processing volume directly affects the project implementation cycle and processing cost. The larger the processing volume, the shorter the implementation cycle and th...

Problems solved by technology

The energy required for the reaction in the kiln is supplied by one end of the kiln body, and the materials in the kiln cannot be heated uniformly along the direction of travel, and the rotary kiln is in the process of continuous rotation, which will cause great disturbance to the processed materials and generate a large amount of dust. The supporting flue gas dust removal treatment system has a large load and high equipment maintenance costs
