Apparatus and method for in-situ destruction of municipal solid waste material

摘要

Municipal solid waste (MSW) is introduced into a primary module (1-3, Fig. 1) to produce a waste feedstock which is gasified in a secondary module comprising a primary plasma gasifier (5, Fig. 1). A generator module generates electricity from synthesis gas produced from the primary gasifier. The primary module (1-3, Fig. 1), secondary module, and generator module are contained in a compact housing suitable for locating in a private dwelling or small commercial premises. Exhaust gas from the secondary module is routed through a ducting assembly comprising a feedback loop to the primary gasifier (5, Fig. 1), and/or a conduit to a secondary plasma gasifier. Primary residual gas is recirculated back to the primary gasifier (5, Fig. 1), and/or to a secondary plasma gasifier, to produce a secondary residual gas. Secondary residual gas produced from the primary or secondary gasifier is vented through a vent. A shredder (2, Fig. 1) may produce a shredded waste feedstock, and a filter module (12, Fig. 1) may remove solid or gaseous residue from the secondary residual gas before venting.
