Sludge adding device in sludge burning system

Abstract

The invention discloses a sludge adding device in a sludge burning system. The sludge adding device comprises a sludge conveying device and a feeding pipe; the upper end of the feeding pipe is connected with a sludge receiving hopper, and an upper opening of the sludge receiving hopper is correspondingly linked with the discharging end of the sludge conveying device; the lower end of the feeding pipe is connected with a sludge burning furnace, and the connecting position of the lower end of the feeding pipe and the sludge burning furnace is located at the zero section of the positive pressure and the negative pressure of the sludge burning furnace; at least one spraying and blowing pipe communicated with the feeding pipe is arranged on the feeding pipe, and is communicated with an air supply system; and when the gas enters the feeding pipe from the spraying and blowing pipes, the gas motion has the branch motion in the direction the same as the sludge flowing direction of the feeding pipe. According to the sludge adding device, the sludge can be fully combusted, sludge feeding is not prone to blockage, and the offensive odor generated in combustion is not prone to escaping.

Description

technical field [0001] The invention relates to a sludge adding device, in particular to a sludge adding device in a sludge incineration system. Background technique [0002] The sludge incineration treatment system is a commonly used treatment method in the sludge treatment plant. The sewage discharged by the sewage discharge unit is treated by the sewage treatment plant and then discharged up to the standard. During the sewage treatment, the sludge will be precipitated. The sludge is prepared and filtered to obtain water content. These mud cakes can be reprocessed, and sludge incineration is a common way of sludge reprocessing. At present, the sludge adding device is to use a sludge hopper and a sludge pipe to send it into the incinerator. The upper opening of the sludge hopper is opened, and the sludge is sent into the sludge hopper by a conveyor belt. This structure has the following Defects: 1. The burning time of sludge is long; 2. Some unpleasant smells will be produ...

Problems solved by technology

At present, the sludge adding device is to use a sludge hopper and a sludge pipe to send it into the incinerator. The upper opening of the sludge hopper is opened, and the sludge is sent into the sludge hopper by a conveyor belt. This structure has the following Defects: 1. The burning time of sludge is long; 2. Some unpleasant smells will be produced when the sludge is burned, and these smells will escape from the sludge pipe, resulting in a strong smell at the incineration site and a bad operating site environment; 3. Sludge enters the sludge pipe and falls by gravity, which may cause sludge blockage
