Embodiment Construction

[0021] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0022] Such as figure 2 As shown, a kind of municipal sludge incineration treatment device provided by the present invention includes a sludge drying device, a fluidized bed incinerator, a flue gas purification system and a chimney. Raw sludge with a high water content is sent to the sludge drying device after undergoing chemical conditioning and physical dehydration (compression dehydration / centrifugal dehydration). oil, etc.) to become dry sludge with low moisture content, and then pass the dry sludge and combustion air into the fluidized bed incinerator for combustion. The device also includes absorption refrigeration and heat pump units. The dry gas generated in the device is connected to the generator of the absorption refrigeration and heat pump units through pipelines as their driving heat source; it also includes a gas-liquid separation device...

Abstract

The invention discloses a municipal sludge incineration disposal device, which comprises a sludge drying device, a fluidized bed incinerator, a smoke purification system and a chimney, wherein the sludge drying device comprises a sludge inlet, a dried sludge outlet, a dried gas outlet and a first pipeline for heat-storage working medium; the fluidized bed incinerator comprises a dried sludge inlet, a gas inlet, a smoke outlet and a second pipeline for the heat-storage working medium; the dried sludge outlet is connected with the dried sludge inlet; the first pipeline for the heat-storage working medium is connected with the second pipeline for the heat-storage working medium to form a circulation loop; the smoke outlet is successively connected with the smoke purification system and the chimney; the dried gas outlet is connected with an absorption-type refrigeration or heat pump unit; the outlet of the absorption-type refrigeration or heat pump unit is connected with a gas and liquid separation device; and the gas outlet of the gas and liquid separation device is connected with a gas inlet. Compared with the prior art, the municipal sludge incineration disposal device disclosed by the invention is characterized in that a spray tower is omitted, and water resource is saved. Meanwhile, the discharge standard is improved, and therefore the municipal sludge incineration disposal device is more environment-friendly.

Description

technical field [0001] The invention belongs to the field of energy technology, and relates to a device and a method for realizing regional combined cooling and heating by using municipal sludge incineration and realizing energy recycling. Background technique [0002] Since the 1970s, the environmental problems caused by municipal sludge have become increasingly prominent. Driven by the acceleration of urbanization in my country, the rapid increase of urban population, and the continuous growth of national investment in environmental protection, the number of sewage treatment plants in my country has increased year after year, and the sewage treatment capacity has continued to increase. The resulting sludge will also maintain a relatively large scale. increase. According to the calculation of the Chinese Academy of Environmental Sciences, by 2010, the wet sludge produced by sewage treatment plants in various cities in my country will reach more than 50 million tons, account...
