Abstract

The utility model provides a composite wet-type high-efficiency desulfurizer. An outer cylinder (1) and an inner cylinder (3) form a sleeve type structure to realize the treatment of desulfurization and purification on smoke of a boiler. A bracket (4) is arranged above the outer cylinder (1) so as to support and fix a chimney (3). After the smoke enters from the outer cylinder (1), treatment is carried out on the smoke by alkali liquid atomized by a nozzle (9) in a ring-shaped cylinder cavity; then, the smoke enters an inner cavity of the inner cylinder (2), dual treatment is carried out on the smoke by the alkali liquid atomized by at least two stages of nozzles (10) and a liquid film formed by a groove (12) in the inner cavity; and the purified smoke is discharged from the chimney (3) arranged above the inner cylinder (2). As the desulfurizer adopts the sleeve type structure, the purifying treatment and smoke discharging are integrated so as to greatly reduce the occupied area. The system resistance is smaller than or equal to 1,200Pa, the dust removing efficiency is equal to or larger than 98%, and the desulfurizing efficiency is equal to or larger than 93%.

Description

A kind of compound Wet-type high-efficient desulfation device

One, technical field

The utility model relates to a kind of fire coal boiler fume treatment facility, specifically a kind of compound Wet-type high-efficient desulfation device.

Two, background technology

In the use of industrial boilers in China, the desulfurizer overwhelming majority adopts chemical tower template and common rotating plate type at present.From their design feature and practical situations, these two kinds of forms exist some defectives and deficiency respectively.The chemical tower template belongs to high efficient gas and liquid quality transmission type equipment, and advantage is the gas-liquid full contact, and time of contact is long, the desulfuration efficiency height.But shortcoming is a steam separation difficulty in the system, and equipment is obvious, and pipeline easily stops up, and system's internal resistance is big, the operating cost height, and floor space is big etc., thereby has influenced being extensive use of of it.

The board-like devulcanizer of the common eddy flow of granite, with its succinct use, cost is low and captured more than half field of burning boiler desulfurization rapidly.But in use also exposed the one side of its deficiency, it is unsatisfactory mainly to show as desulfurized effect, and equipment and auxiliary equipment floor space are big, and water consumption is bigger than normal, and pipeline and nozzle easily stop up plug etc., and system's internal resistance is big.

Three, summary of the invention

The utility model aims to provide a kind of devulcanizer of efficient boiler flue gas, and technical problem to be solved is to reduce intrasystem resistance and reduce floor space.

The technical solution of the utility model comprises urceolus 1 and inner core 2, difference with the prior art is that urceolus 1 and inner core 2 constitute the desulfurizing and purifying processing of telescoping structure realization to boiler smoke, flue gas after being purified is from chimney 3 dischargings that are arranged on inner core 2 tops, support 4 is set above urceolus 1 to be realized to the support of chimney 3 and fixing, as shown in Figure 1.Gas approach 5 and two discharge outlet 6 are set on urceolus 1, chimney import 7 and two delivery ports 8 of distributing along barrel are arranged, in the bottom of inner core 2 as Fig. 2, shown in Figure 3.Be provided with circumferential nozzle 9 in the annular canister chamber between urceolus 1 and inner core 2, effect is that the alkali lye that will atomize spreads in the chamber; At least up and down double-stage nozzle 10 is set in the inner chamber of inner core 2, adjacent double-stage nozzle mutual dislocation, effect is that the alkali lye that will atomize spreads in the inner chamber, as shown in Figure 1.The top of inner core 2, just the tube inwall above the upper level nozzle is provided with an eaves 11, forms downward groove 12 between tube eaves 11 and the barrel, and effect is absorption liquid (alkali lye or water) to be sprayed to groove just form complete liquid film downwards from groove.

This devulcanizer is as follows to the sweetening process of flue gas:

Flue gas from sack cleaner (perhaps blower fan outlet, this moment, this devulcanizer had the dedusting effect concurrently) tangentially rotates in the annular canister chamber from gas approach 5, and at first the alkali lye that is atomized by nozzle 9 is handled once most of dust and SO in the flue gas ₂Be absorbed processing, enter in the inner chamber from gas approach 7 then, the dual processing of liquid film that alkali lye that is atomized by nozzle 10 and groove 12 form, remaining dust and SO in the flue gas ₂The overwhelming majority is absorbed processing, and the flue gas that is desulfurized purification enters atmosphere from chimney 3.Wrapped folder dust and is absorbed with SO ₂Alkali lye enter the liquid waste processing pond from

discharge outlet

6 and 8.

This devulcanizer is designed to telescoping structure with original discrete major-minor tube, and chimney and devulcanizer are formed integral body, and this has just significantly reduced floor space.Finish the treatment and purification process in the inner chamber of tube chamber and the inner core of flue gas between inner/outer tube, additional devices such as equal acylic motion plate, deflector and stem stem in tube chamber and the inner chamber, and flue gas after being purified directly enters smoke stack emission, this significantly reduces with regard to the internal resistance that makes system, after tested, SR≤1200pa, efficiency of dust collection 〉=98%, desulfuration efficiency 〉=93%, 70～80 ℃ of exit gas temperatures.

This devulcanizer is applicable to that 35T/h～240T/h industry coal-boiler gas cleaning handles, can with electric cleaner or the supporting use of sack cleaner.The applicant designs, has built this devulcanizer for many companies, and the every index of fume emission meets the GB requirement.

Five, the specific embodiment

Get high-quality granite and build the urceolus 1 and the inner core 2 of telescoping structure, set up chimney 3 on inner core 2, erection bracket 4 on urceolus 1, and 4 pairs of chimneys of support 3 are realized supporting and be fixing.As shown in Figure 1.

Two discharge outlet 6 of gas approach 5 and radial symmetric are set, as shown in Figure 2 on urceolus 1.

On inner core 2 bottom barrels, be distributed with gas approach 7, as shown in Figure 3, two discharge outlet 8 radial symmetric.As shown in Figure 2.

Form the annular canister chamber between urceolus 1 and inner core 2, eight nozzles 9 that are uniformly distributed along the circumference in the tube chamber atomize the alkali lye of pH value 8 ± 0.5 in the tube chamber.
