Synthetic acid mist absorption treatment device

Abstract

The invention relates to a synthetic acid mist absorption treatment device. The device comprises a storage tank, a hydraulic jet pump, an intermediate groove and an acid water circulation groove, wherein the storage tank is communicated with the air inlet port of the hydraulic jet pump through a gas collecting pipe; a second blow-down pipe and a return pipe are arranged on the intermediate groove; the other end of the return pipe is communicated with the water return port of the hydraulic jet pump; the lower end of the intermediate groove is provided with a drainage port; a liquid inlet pipe, a first blow-down pipe, and a pure water replenishing pipe are arranged on the acid water circulation groove; one end of the liquid inlet pipe extends to the bottom of the acid water circulation groove, and the other end of the liquid inlet pipe is communicated with the drainage port on the lower end of the intermediate groove; the lower end of the acid water circulation groove is provided with a liquid discharge port, and the liquid discharge port is connected with a circulation pump through a pipeline; the circulation pump is communicated with the liquid inlet port of the hydraulic jet pump through a circulation pipe; the circulation pipe is further communicated with a high-purity acid replenishing pipe; a first valve is arranged on the high-purity acid replenishing pipe. Therefore, the device can perform effective absorption treatment on acid mist synthesized by hydrochloric acid, and can also reduce secondary pollution.

Description

technical field [0001] The invention belongs to the field of chemical machinery and equipment, and in particular relates to a synthetic acid mist absorption treatment device. Background technique [0002] In the field of chemical industry, hydrochloric acid has been widely used. Due to its strong volatility, hydrochloric acid is often volatilized from storage devices to form synthetic acid mist, which not only pollutes the environment, but also causes damage to the health of workers. Therefore, it is necessary to Synthetic acid mist is recycled and processed. The original synthetic acid mist is absorbed, and the primary water is used to absorb it through the jet pump. The acidic wastewater after absorption is directly poured into the hydrochloric acid storage tank. Since the acidic wastewater in the hydrochloric acid storage tank cannot be treated, it takes a long time It is also prone to acid mist, which not only corrodes the surrounding equipment, but also becomes a new so...
