Device for recycling hot waste gas generated in production process of -2-aminobutyric acid salt ammonium salt and using method thereof

Abstract

The invention disclose a device for recycling hot waste gas generated in the production process of -2- aminobutyric salt ammonium salt and a using method thereof. The device comprises a drying chamber, a hot waste gas pipe, a brick baking chamber, an exhaust pipe, a purification tower, gas inlets, a conveyor belt, rotating shafts, a first gas inlet pipe, a second gas inlet pipe, a spiral pipe, a water tank, a water pumping port and a partition plate. The device has the beneficial effects that the drying chamber and the brick baking chamber are connected together through the hot waste gas pipeso that the hot waste gas generated through baking the bricks can be recycled to dry green bricks; the gas inlets of the hot waste gas pipe are formed in the two sides of the drying chamber, the convection of the hot waste gas can be realized through the two gas inlets, the hot waste gas can be uniformly mixed, so that the contact area between the green bricks and the hot waste gas is increased, and the drying speed is accelerated; and the water tank is arrange on the partition plate, the circle of spiral pipe is arranged on the outer wall of the periphery of the water tank, and therefore theused hot waste gas passes through the spiral pipe to heat the water tank, and the waste heat of the hot waste gas is fully utilized. The device has the characteristics of being high in drying speed and capable of better utilizing the waste heat.

Description

technical field [0001] The invention relates to a recovery device, in particular to a recovery device for producing medium-heat waste gas with 2-aminobutyrate ammonium salt and a method for using the same, belonging to the application field of 2-aminobutyrate ammonium salt treatment. Background technique [0002] -2-Aminobutyrate ammonium salt will produce waste gas during the reproduction process. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before being discharged to the outside, so as to meet the national waste gas discharge standards. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment, air sterilization, disinfection and purification, etc. The recycling of hot waste gas generated by brick burning factories can effectively reduce energy consumption. [0003] However, there are still certain defects in the exist...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that although the above-mentioned existing hot waste gas recovery device can use the hot waste gas to dry the bricks, when drying the bricks, since the area of ​​the hot waste gas contacting the bricks is small, it is difficult for the drying of the bricks. The drying efficiency is low, a lot of hot exhaust gas is wasted, and the heat of the hot exhaust gas is not absorbed. The heat flowing into the purification tower can easily slow down the reaction rate of the chemical agents in the purification tower and increase the purification cost. Provide a A recovery device for medium-heat waste gas produced by ammonium-2-aminobutyrate and its use method, which have the advantages of fast drying rate and more sufficient use of waste heat
