Abstract
The utility model discloses waste acid or alkali steam treatment equipment, which comprises an absorption tower, an absorption liquid circulating device, an intake fan and an exhaust pipe. One to three groups of conical screens are parallelly arranged in the absorption tower, cone tops of each two conical screens are opposite and form a group, the absorption liquid circulating device comprises an absorption liquid storage tank, an absorption liquid circulating pump, an absorption liquid inlet pipe, an absorption liquid recovery pipe and an absorption liquid sprayer, the absorption liquid sprayer is arranged at the top of the absorption tower, and absorption liquid pH (potential of hydrogen) value detectors are arranged in the absorption liquid inlet pipe and the absorption liquid recovery pipe respectively and connected with a rotation speed regulator arranged on a motor of the absorption liquid circulating pump 7. The waste acid or alkali steam treatment equipment is simple in structure and small in occupied area, owing to the conical screen groups, steam and liquid sufficiently contact with each other, exhaust is smooth, the screens are made of plastics, installation and maintenance are facilitated, spraying rate is regulated according to pH values of inlet absorption liquid and recovered absorption liquid in the absorption liquid circulating device, and the equipment is stable in absorption, low in energy consumption, high in purification efficiency, economical and practical.
Description
Technical field
The utility model belongs to chemical field, exactly is spent acid or alkali steam treatment device.
Background technology
In the Production in Chemical Plant process, particularly wet method is closed in the process of inorganic salt product at present, produces a certain amount of acidity or alkaline waste vapour through regular meeting.Not only endanger producers' health, the corrosion plant and equipment have polluted environment; Along with the progress of science and technology, also increasingly high to the requirement of chemical products, the chemical enterprise automaticity also improves constantly; Various electronic equipments are number of applications in Chemical Manufacture enterprise; Soda acid steam is very harmful to electronic equipment, if improper to the spent acid alkali steam treatment in the production environment, directly influences the ordinary production of enterprise; Percent defective increases, and serious meeting causes equipment scrapping.To enterprise's band massive losses.It is related to the problem of Business survival.
Therefore, chemical enterprise is more and more paid attention to the processing of soda acid steam.The treatment facility of existing spent acid alkali steam; Be that spent acid alkali steam is introduced purifying column by airduct, through packing layer, waste gas and absorption liquid carry out the abundant absorbing contacting neutralization reaction of gas-liquid two-phase; Spent acid alkali steam enters atmosphere by blower fan again through after purifying behind demist plate dehydrating demisting.Absorption liquid recycles at the bottom of after the water pump supercharging, descending at the cat head spray at the bottom of the tower, being back to tower at last.Generally the treatment facility structure of the spent acid alkali of use is quite complicated in the market, and cost is high, investment is big, floor space is also very big, and consumable accessory replacing difficulty, and service life is shorter.Caused operating cost high.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, energy consumption is low, purification efficiency is high, floor space is little spent acid or alkali steam treatment device.
Spent acid or alkali steam treatment device, it is made up of absorption tower, absorption liquid EGR, air intake machine, exhaust duct, is provided with screen cloth in the described absorption tower; Screen cloth is taper, and the vertex of a cone of two taper screen clothes is relative, becomes one group; Total 1-3 group in the absorption tower; Be arranged in parallel within the absorption tower, the absorption liquid EGR is made up of absorption liquid storage tank, absorption liquid circulating pump, absorption liquid inlet pipe, absorption liquid recovery tube, absorption liquid shower nozzle, and the absorption liquid shower nozzle is located at the top, absorption tower; Be respectively equipped with absorption liquid pH value detector in absorption liquid inlet pipe and the absorption liquid recovery tube, be provided with the rotating speed demodulator with absorption liquid circulating pump 7 motors and link to each other.
Screen cloth in the absorption tower is 1 group;
Screen cloth is a plastic material.
Spent acid that the utility model provides or alkali steam treatment device, spent acid or alkali steam are gone into the bottom, absorption tower by the air intake power traction, and spent acid or alkali steam are from bottom to top; Absorption liquid sprays downwards at cat head after the supercharging of absorption liquid circulating pump; Under the effect of taper screen cloth group, the abundant mutually absorbing contacting of vapour-liquid two, absorption liquid pH value detector detects the absorption liquid pH value before and after the contact respectively; Transfer the rotating speed of absorption liquid circulating pump according to their poor demodulator; Control absorption liquid spray flux after spent acid or alkali steam have obtained sufficient purification, is discharged through exhaust duct.
Spent acid that the utility model provides or alkali steam treatment device, simple in structure, floor space is little, owing to adopted taper screen cloth group; The abundant mutually full contact of vapour-liquid two, exhaust is unobstructed, and screen cloth adopts plastic material; Installation and maintenance are convenient; PH value difference according to advancing, return absorption liquid in the absorption liquid EGR is reconciled spray flux, and absorption is stable, energy consumption is low, purification efficiency is high, and is economic and practical.
Description of drawings
Accompanying drawing is the utility model spent acid or alkali steam treatment device sketch map.
The specific embodiment
See also accompanying drawing, spent acid or alkali steam treatment device, it comprises: absorption tower 1, absorption liquid EGR, air intake machine 5, exhaust duct 4; Be provided with screen cloth 2 in the described absorption tower 1, screen cloth 2 is taper, and the vertex of a cone of two taper screen clothes 2 is relative; Become one group, total 1-3 group in the absorption tower 1, present embodiment adopts 1 group; Screen cloth 2 is stainless steel or plastic material, and preferred plastic material is arranged in parallel within the absorption tower 1; The absorption liquid EGR is made up of absorption liquid storage tank 6, absorption liquid circulating pump 7, absorption liquid inlet pipe 8, absorption liquid recovery tube 9, absorption liquid shower nozzle 3, and the absorption liquid shower nozzle is located at 1 top, absorption tower, is respectively equipped with absorption liquid pH value detector 11, pH value detector 12 in absorption liquid inlet pipe 8 and the absorption liquid recovery tube 9; Absorption liquid circulating pump 7 motors are provided with rotating speed demodulator 10; Rotating speed demodulator 10 is according to the rotating speed of the difference conciliation absorption liquid circulating pump 7 of absorption liquid inlet pipe 8 and absorption liquid recovery tube 9 interior absorption liquid pH values, and the big more rotating speed of difference is high more, and the little rotating speed of difference is low.
The utility model spent acid or alkali steam treatment device, spent acid or alkali steam are gone into the bottom, absorption tower by the air intake power traction, and spent acid or alkali steam are from bottom to top; Absorption liquid sprays downwards at cat head after the supercharging of absorption liquid circulating pump; Under the effect of taper screen cloth group, the abundant absorbing contacting of gas-liquid two-phase, absorption liquid pH value detector detects the absorption liquid pH value before and after the contact respectively; Transfer the rotating speed of absorption liquid circulating pump according to their poor demodulator; Control absorption liquid spray flux after spent acid or alkali steam have obtained sufficient purification, is discharged through exhaust duct.
