Problems solved by technology
[0005] 1. During the working process of the hydrogen chloride tail gas recovery device, the energy consumption is often large, and the waste heat generated by cooling water, spray water and heat exchange is difficult to recycle, so that there is a certain amount of energy loss and waste in the process of energy recovery , not conducive to energy-saving production
[0006] 2. During the working process of the hydrogen chloride tail gas recovery device, the recovery is often not thorough enough, resulting in the loss and waste of energy and recyclable waste

The invention discloses an efficient recycling device and method for hydrogen chloride tail gas, and belongs to the technical field of waste gas recycling treatment. In order to solve the problem that the energy-saving effect is poor due to the fact that energy consumption is large and energy cannot be recycled in the recycling process, a circulating water pump is arranged on the front face of a water storage tank, circulating cooling water can be subjected to heat exchange refrigeration in the water storage tank, and therefore the cooling water can be continuously used; a fixed ring and a rotating ring are rotatably connected, a middle rotating shaft of a rotating fan blade is fixedly connected with a connecting frame, an air guide hopper is arranged at the bottom of the rotating ring, side lines are arranged on the outer wall of the air guide hopper, and the air guide hopper rotates to drive hydrogen chloride tail gas to move, so that waste gas can be recycled more sufficiently; and the rotating fan blades are driven to rotate automatically through flowing of the waste gas, so that the waste gas recycling effect is improved, and meanwhile, the energy consumption is prevented from being increased.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a device and method for efficient recovery and utilization of hydrogen chloride tail gas. Background technique [0002] Hydrogen chloride tail gas is mainly produced in the production process of chemical industry, electroplating, papermaking, grease and other industries, especially in the pickling process, a large amount of HCI waste gas is often generated. [0003] Hydrogen chloride, the chemical formula is HCl, a hydrogen chloride molecule is composed of a chlorine atom and a hydrogen atom, is a colorless gas with a pungent odor. Its aqueous solution is commonly known as hydrochloric acid and the scientific name is hydrochloric acid. Hydrogen chloride is very soluble in water. At 0°C, 1 volume of water can dissolve about 500 volumes of hydrogen chloride. Hydrogen chloride waste gas has strong corrosiveness to the environment and equipment, is harmful to human...
