Embodiment Construction

[0016] The present invention utilizes the wet sludge atomization nozzle to atomize the wet sludge, utilizes the plant liquid atomization nozzle to atomize the plant liquid, and makes the wet sludge atomized droplet and the plant liquid atomized droplet form a 90-degree opposite spray, so that The two are fully mixed and deodorized, and the mixed atomized liquid droplets are sprayed on the surface of the non-stick track, and while moving along the direction of the casing cylinder at a set speed, the heated water that is closely attached to the non-stick track The plate transfers the energy required for drying to the sludge in the form of contact heat transfer, so that the sludge is dried to the required degree, and then the dried sludge is cooled to the required temperature through the cooling plate closely fitted with the non-stick track The deodorized and dried sludge is cut by the material breaker, falls into the discharge pipe at the lower part of the machine body, enters th...

Abstract

The invention provides a sludge drying, deodorizing and conveying integrated device. The device mainly comprises a wet sludge conveying and spraying device, a plant liquid conveying and spraying device, a sludge drying, deodorizing and conveying machine body, a heating/cooling medium conveying loop and a tail gas treatment device. A plurality of non-stick crawler belts are adopted for the sludge drying, deodorizing and conveying machine body and are made to be arranged in a machine shell in the longitudinal direction, and a wet sludge atomizing nozzle and a plant liquid atomizing nozzle which flush against each other are arranged at the starting end of each crawler belt; the wet sludge atomizing nozzles are utilized to atomize wet sludge, the plant liquid atomizing nozzles are utilized to atomize plant liquid, and the wet sludge atomizing nozzles and the plant liquid atomizing nozzles are made to be fully mixed to conduct deodorization. The sludge is dried to the required degree in a contact heat transfer mode through heating plates which are tightly attached to the non-stick crawler belts, and then the sludge is cooled to the required temperature through cooling plates which are tightly attached to the non-stick crawler belts. By means of the sludge drying, deodorizing and conveying integrated device, the problem that bad smell is spread all over a field area of a sludge drying incineration engineering project can be solved, and continuous drying and conveying of the sludge can be achieved.

Description

technical field [0001] The invention relates to an integrated device for sludge drying, deodorization and transportation, which belongs to the technical field of sludge drying, deodorization and transportation. Background technique [0002] The output of municipal sludge is huge and its composition is complex. How to dispose and utilize municipal sludge has become a concern of people. The treatment and disposal of sludge should take "reduction, stabilization, and harmlessness" as the ultimate goal. Sludge drying is a treatment method for deep dehydration of sludge using artificial heat sources and industrial equipment. Its operating temperature is usually higher than 100°C. The drying effect on sludge is not only deep dehydration, but also has the effect of heat treatment; in addition, The moisture content of the product of sludge drying treatment can be controlled below 30%, which can inhibit the activity of microorganisms in the sludge, so the sludge drying treatment can ...
