Deodorization tower device capable of realizing dusty and oily damp and hot gas temperature regulation

Abstract

The invention discloses a deodorization tower device capable of realizing dusty and oily damp and hot gas temperature regulation. The deodorization tower device comprises a deodorization tower body, filler layers, a special-shaped tube type heat exchanger, an atomization spraying device, a circulation cooling device, a chemical dosing device and an intelligent control system, wherein the deodorization tower body comprises a gas inlet pipe arranged at the lower side of the tower body; the plurality of filler layers are sequentially arranged in the tower body from bottom to top; a liquid collecting tank is arranged at the lower part of the tower body, and a belt type oil removal machine is placed on the liquid collecting tank; the special-shaped tube type heat exchanger arranged at the upper end of the tower body comprises a cooling water inlet pipe, a hot water outlet pipe, a flushing pipe used for cleaning tubes, and a blow-off pipe used for discharging oil and sewage; a purified gas exhaust pipe is connected with the tube type heat exchanger and a subsequent device; the atomization spraying device comprises a circulating water channel, a circulating spray water pump, a Y-shaped filter, a spray atomization pipeline, and a circulation pipeline pressure gauge and a nozzle which are arranged at the outer side of the pipeline.

Description

technical field [0001] The patent of the present invention relates to the field of waste gas treatment, in particular to a deodorizing tower device for treating dusty and oily hot and humid gas and realizing temperature regulation. Background technique [0002] Food waste has the characteristics of high water content, high oil content, and high organic matter content: the water content is generally greater than 85%, and the oil content is about 2-5%. During the treatment of food waste and waste animal and vegetable oils in the process of oil-water separation through moist heat treatment, a large amount of oily, dusty and foul-smelling hot and humid gas will be produced. This kind of gas needs to be cooled, dusted, degreased, deodorized and dried, and finally meets the national or local emission standards for odor pollutants before being discharged up to the standard. [0003] Domestic treatment of the odor produced by kitchen waste and waste oil mainly uses chemical methods...

AI Technical Summary

Problems solved by technology

[0004] The limitations of conventional treatment methods are mainly reflected in: the oil in the gas will adhere to the equipment and pipelines, forming an oil film, causing damage to equipment, excessive wind resistance of pipelines, and reduced heat transfer rate; low-temperature plasma combined with photocatalytic degradation requires the intake air to be between -50 and 50 It is not suitable for processing the high-temperature gas involved in the patent of the present invention; when using physical and biological adsorption methods, the high temperature increases the activation energy of molecules, which reduces the adsorption effect; under high temperature conditions, it is not suitable for microbial metabolic reactions; damp heat The odor is acidic and corrosive to a certain extent, and has a corrosive effect on the pipes connected to the odor treatment systems; the dusty gas will block the intake pipes and the pipes connected to the processing equipment, resulting in a reduction in the pipeline’s delivery capacity and affecting the equipment. problems with normal operation

[0005] This shows that there are many inconveniences and defects in the above-mentioned existing deodorizing series methods, and urgently need to be improved.
