Abstract

The utility model provides a dry tail gas recycle device of naphthalene water reducing agent. The device is equipped with the tail gas pipe in the bottom of chimney, is equipped with the air -blower on the tail gas pipe, and open the bottom of chimney has the chimney manhole, is equipped with the baffle in the chimney, and the spray thrower is equipped with on the upper portion of baffle, and the spray thrower is linked together with the inlet tube, is equipped with the converter tube on the inlet tube and says the pump, and during the other end of inlet tube stretched into the sedimentation tank, the delivery pipe was equipped with to the bottom of sedimentation tank, and the opposite side of chimney is equipped with the wet return, and the wet return lets in in the sedimentation tank. The device will contain the vapor of solid dust product in a large number, through baffle in the chimney and spray thrower, make vapor increase dwell time in the chimney, and the condensation of the solid dust product of being convenient for is retrieved and is recycled.

Description

A kind of naphthalene water reducer is dried tail gas recycling device

Technical field

This utility model relates to field of chemical equipment, is related specifically to a kind of naphthalene water reducer and is dried tail gas recycle utilization Device.

Background technology

It is dried in production at naphthalene water reducer mother solution at present, commonly used water reducer mother solution is sprayed in drying tower, make Moisture evaporation in mother solution, is arranged in air by pipeline the most in gaseous form, and the pressed powder settled is final products, This operational approach there are following defect:

1, the final products obtained in process of production are solid dust shape, after the cyclone dust removal of air stove is collected, Also having substantial amounts of solid dust product to arrange in air with hot steam, this traditional exhaust mode can cause product A large amount of losses, production efficiency is low, and economic loss is bigger；

2, the solid dust product which produces is the chemical substance being harmful to health, with steam row to the powder of air Dirt, falls after rise in the Nature after cooling in atmosphere, can cause serious environmental pollution.

Summary of the invention

The purpose of this utility model is to provide one to utilize spray thrower, baffle plate, frequency conversion pipeline pump and sedimentation tank to come effectively Reclaim product naphthalene water reducer be dried tail gas recycling device.

For achieving the above object, the technical solution of the utility model is:

A kind of naphthalene water reducer is dried tail gas recycling device, including chimney, spray thrower, baffle plate, chimney manhole, frequency conversion Pipeline pump, water inlet pipe, return pipe, sedimentation tank, aerator, offgas duct and delivery pipe, described device in the bottom of chimney equipped with tail Trachea, equipped with aerator in offgas duct, the bottom of chimney has chimney manhole, chimney built with baffle plate, the top of baffle plate equipped with Spray thrower, spray thrower is connected with water inlet pipe, and equipped with frequency conversion pipeline pump on water inlet pipe, the other end of water inlet pipe extend into sedimentation tank In, the bottom of sedimentation tank is passed through in sedimentation tank equipped with return pipe, return pipe equipped with delivery pipe, the opposite side of chimney.

Good effect of the present utility model is:

1, this device will contain the steam of solid dust product in a large number, by the baffle plate in chimney and spray thrower, makes water Steam increases the time of staying in chimney, it is simple to the condensation recycling of solid dust product；

2, this device can strengthen recovery product efficiency, reduces solid dust environmental pollution, reduces production cost simultaneously, Increase income；

3, this device can promote production environment excellentization further, makes generation and natural environment safety and environmental protection.

Accompanying drawing explanation

Fig. 1, naphthalene water reducer are dried tail gas recycling device structural representation.

Detailed description of the invention

1 carries out clear, complete description to the technical solution of the utility model further below in conjunction with the accompanying drawings.

Seeing accompanying drawing 1, the dry tail gas after dedusting is blasted in chimney 1 by offgas duct 10 by aerator 9, same to time-varying Frequently sedimentation tank 8 water at the middle and upper levels is sent in spray thrower 2 and sprays to the lower section of chimney 1 by water inlet pipe 6 by pipeline pump 5, due to Chimney 1 is mounted with multilamellar baffle plate 3, therefore shower water and tail gas is defined obstruct, add tail gas flowing in chimney 1 Time and the time of contact of shower water, so that solid dust product in tail gas and impurity are after fully washing, with shower water Falling into the bottom of chimney 1 together, finally enter sedimentation tank 8 from return pipe 7, the precipitate bottom sedimentation tank 8 reaches certain After degree, open the valve on delivery pipe 11, the water in sedimentation tank 8 is discharged together with precipitate, at BSW process More recoverable after reason.When falling into the big dust particle bottom chimney 1 and cannot enter in sedimentation tank 8 with water, will pile up In the bottom of chimney 1, the most over time, it is necessary to open the chimney manhole 4 dust to being deposited on bottom chimney 1 and carry out clearly Reason, the dust that clears is treated can be again with.

This device produces the data of recovery raw material and is shown in Table 1 before and after using
