Thin-layer dry distillation gasification device, dry distillation equipment and dry distillation method

Abstract

The invention discloses a thin-layer dry distillation gasification device, dry distillation equipment and a dry distillation method. The thin-layer dry distillation gasification device comprises a furnace body with a furnace cavity, wherein the furnace body comprises a preheating section, a low-temperature section, a medium-temperature section and a cooling section which are arranged in sequence from top to bottom; a gas collection cavity with a gas collection hole and a plurality of tubular combustors are arranged in the furnace cavity; a radiation heating cavity is formed between the tubular combustors and the side wall of the furnace body; a radiation gas inlet cavity is formed in the lower part of the radiation heating cavity; a gas collection cover is arranged above the gas collection cavity; the gas collection hole of the gas collection cover faces to the top of the gas collection cavity; an outlet pipe communicated with the inside of the gas collection cover is arranged on the gas collection cover; a partition wall between the radiation gas inlet cavity and the furnace cavity gradually tilts to the inside of the furnace cavity in a direction from bottom to top. According to the structural design of the thin-layer dry distillation gasification device, the problem of relatively high heat loss in a dry distillation process of the thin-layer dry distillation gasification device can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, and more specifically relates to a thin-layer dry distillation gasification device, dry distillation equipment and a dry distillation method. Background technique [0002] Rich in coal, short of oil, and low in gas are the characteristics of my country's energy structure. As the pillar of my country's economic development, coal occupies a dominant position in primary energy consumption, and its absolute consumption increases with economic development. Considering the structure of energy resources and energy security, and at the same time restricted by oil and gas resources at home and abroad, based on my country's rich coal resources, develop a coal chemical industry chain oriented by clean coal technology, and use coal as raw materials to produce alcohol fuels and oil. Commodity fuels, natural gas fuels, olefins, dimethyl ether and other petroleum substitutes, coal substitution fo...
