Description

Waste incineration flue gas cooling and dust removing device

Technical Field

The utility model relates to the technical field of environment-friendly equipment, in particular to a waste incineration flue gas cooling and dedusting device.

Background

At present, the research and application of the waste incineration power generation technology become one of the major hot topics in the world, and the research and application of the waste incineration power generation technology and equipment are widely concerned by governments and scientific research personnel in various countries in the world, so that the waste incineration power generation technology and equipment related to the foreign countries have been partially applied to the industry. The waste incineration power generation can recycle the waste, reduce the coal power generation and protect the environment and resources. The waste incineration can produce smoke containing dust, the smoke is directly discharged into the atmosphere to cause serious air pollution to the environment, and the smoke needs to be subjected to dust removal treatment. The high temperature resistance of the existing filter bag type dust removal equipment is general, heat exchange can be carried out before flue gas dust removal, the temperature of the flue gas is reduced, but dust particles in the flue gas still contain higher temperature, the structure of a filter bag can be damaged, the dust removal capacity of the equipment is reduced, and the service life of the equipment is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a waste incineration flue gas cooling and dedusting device to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides a waste incineration flue gas cooling and dedusting device which comprises a dedusting box, wherein the interior of the dedusting box is divided into an air purifying chamber and a dedusting chamber through a partition plate, a plurality of dedusting bag structures are uniformly distributed on the partition plate, an air outlet pipe is arranged on one side of the air purifying chamber, an air inlet pipe is arranged on the side face of the bottom of the dedusting chamber, a dust outlet is arranged at the bottom of the dedusting box, a cooling water tank and a water pump are arranged outside the dedusting box, a heat exchange pipe is arranged inside the dedusting box and is arranged above the air inlet pipe, two ends of the heat exchange pipe are respectively connected with a water inlet pipe and a water outlet pipe, the water inlet pipe is connected with the bottom of the cooling water tank through the water pump, and the water outlet pipe is connected with the top of the cooling water tank.

Furthermore, the heat exchange tubes are of a multilayer pipeline structure, pipelines on different layers are connected through a transfer space, and the pipelines on different layers are arranged in a staggered mode.

The utility model has the beneficial effects that: set up hot exchange pipe in the dust removal case, the flue gas is got into by the intake pipe, passes from hot exchange pipe's gap, and hot exchange pipe realizes cooling to dust particle in flue gas and the flue gas, simple structure, and the cooling is obvious, can avoid high temperature dust particle in the flue gas to destroy the filter bag, and the practicality is strong.
