Abstract

The utility model discloses a kiln head waste gas recycling device for cement production. The kiln head waste gas recycling device comprises a kiln head dust collector, a kiln head electrical room, a head exhaust fan, a grate cooler, a kiln head platform, an electric air valve, an expansion joint, a first grate cooler secondary section cooling fan, an air pipe, a plugboard valve and a second grate cooler secondary section cooling fan. The kiln head waste gas recycling device has the advantages that: the waste heat in the waste gas can be effectively recovered, the temperature of cooling air of the grate cooler secondary sections on clinker is increased, the temperature of inlet air and smoke of a kiln head boiler is increased, and the evaporation capacity of the boiler is increased, so that the power generation capacity is improved, the heat energy loss can be reduced, the production cost is reduced and the like.

Description

A kind of manufacture of cement is with kiln hood waste gas recycle device

Technical field

The utility model relates to the building materials industry technical field, is specifically related to a kind of manufacture of cement with kiln hood waste gas recycle device.

Background technology

At present, clinker cement production line power generation process with waste heat kiln hood AQC boiler under existing clinker production technology, does not reach the rated capacity of boiler, and the air intake wind-warm syndrome that subject matter is present in the AQC boiler does not reach the desired temperature of boiler.

In order to solve the problems referred to above that exist in the prior art, this patent provides a kind of new solution.

The utility model content

The purpose of the utility model is to provide a kind of manufacture of cement with kiln hood waste gas recycle device for the problem that solves above-mentioned prior art existence; This manufacture of cement can reclaim the waste heat in the waste gas effectively with kiln hood waste gas recycle device; Improve two sections cooling wind-warm syndrome of cooling machine to grog; Increase the air intake cigarette temperature of kiln hood boiler, thereby the evaporation capacity that improves boiler improves generated energy, advantage that the while can reduce that heat energy loss reduces production costs etc.

For reaching the foregoing invention purpose, the technical scheme that the utility model adopted is: provide manufacture of cement with kiln hood waste gas recycle device, comprise kiln hood dust-precipitator, kiln hood electric panel room, an exhaust blower, cooling machine and kiln hood platform; It is characterized in that: also comprise Electric air valve, expansion joint, two sections cooling blowers of the first cooling machine, airduct, push-pull valve and two sections cooling blowers of the second cooling machine;

Said kiln hood dust-precipitator is positioned at kiln hood electric panel room top; The outlet of kiln hood dust-precipitator is connected with the import of an exhaust blower; The outlet of said exhaust blower is connected with the import of discharge duct and airduct respectively; The outlet of said airduct is connected with the import of two sections cooling blowers of the two sections cooling blowers of the first cooling machine and the second cooling machine respectively; Said push-pull valve is between two sections cooling blowers of the first cooling machine and two sections cooling blowers of the second cooling machine; The import department of the import department of the import department of said airduct, two sections cooling blowers of the first cooling machine and two sections cooling blowers of the second cooling machine is respectively arranged with Electric air valve and expansion joint; Said Electric air valve with connect with expansion joint, Electric air valve is connected with programmable logic controller (PLC).

In sum, the manufacture of cement that the utility model provided has following advantage with kiln hood waste gas recycle device than existing situation:

1, this device can improve power generation process with waste heat kiln hood AQC boiler air intake cigarette temperature effectively, increases the evaporation capacity of kiln hood AQC boiler, improves the cogeneration amount;

2, can just in time regulate its aperture by prosecutor in the waste heat according to DCS control Electric air valve, increase work efficiency effectively, and can reduce heat energy loss and reduce production costs.
