Problems solved by technology

However, the implementation of the above methods cannot completely solve the problem of alkali return, especially in areas with high groundwater levels and high salinity, once there is a lack of fresh water, the ground saline-alkali water level will rise, and the land will be re-salinized and the improvement effect will be poor.
[0003] However, the soil quality in most areas of our country is relatively hard, and the air permeability cannot meet the c

Embodiment 1

[0014] The surface soil of the saline-alkali land is leveled and excavated with buried pipe grooves, in which the alkali discharge pipeline is arranged in the buried pipe groove, and the alkali discharge pipeline includes the upper alkali discharge python pipe and the lower alkali discharge python pipe, and the upper alkali discharge pipe is set The vertical direction between the adjacent pipelines of the lower alkali discharge pipes is staggered. One end of the upper alkali discharge pipe and the lower alkali discharge pipe is connected to the vacuum pipe, and the end of the vacuum pipe is connected to a vacuum pump, and the vacuum pump is connected to the power unit. When carrying out alkali discharge work, fresh water is poured on the surface of the ground, and the underground alkali discharge pipes are connected with vacuum pipes, the vacuum pump is turned on, and the alkali discharge pipes are pumped through the vacuum pipes to form a negative pressure. With the positive p...

Embodiment 2

[0016] There is an observation well connected to the ground at the other end of the alkali discharge pipe, and the working conditions of the alkali discharge pipe can be observed from the ground. Specifically, it can be observed on the ground whether the alkali discharge pipe is blocked and the water filtration speed. And at the end of the other end of the alkali discharge pipe, a quick-fit joint can be installed to clean the alkali discharge pipe. The ends are connected, and the quick-fit joint is connected to the high-pressure pump through the pipeline. Under the operation of the high-pressure pump, the alkali discharge pipe is subjected to high-pressure flushing and membrane recoil, and the blockage in the alkali discharge pipe is washed away, ensuring The smoothness of the pipeline and the water filtration capacity of the filter membrane, because the quick-fit joint is detachable, it can be installed when the alkali discharge pipe needs to be cleaned, and removed when it is...

Embodiment 3

[0018] In the early stage of pipe distribution, the present invention firstly leveled and plowed the land, and loosened the soil with a ripper. It is easier to discharge alkali during pressure pouring.

[0019] Through the double function of negative pressure and positive pressure, the present invention achieves the improved effect without a large amount of fresh water resources, and does not need a long time of alkali discharge process, and the alkali discharge cycle is at least shorter than the traditional method of alkali discharge After one year, the most obvious effect will be achieved in that year, and the best effect will be achieved in the second year. The alkali discharge efficiency is twice that of the traditional alkali discharge method, and in areas with strong wind and more solar resources, the use of wind energy and solar energy can directly As a power source, the operating cost is reduced, and the effect of green power changing to alkali is achieved. It is very ...

Abstract

The present invention provides a wind-power vacuum alkali reduction apparatus for reclamation of saline and alkaline land and a use method of the apparatus. The technical scheme is characterized in that an alkali removal pipe path is vertically composed of upper layer alkali removal pipes (1.1) and lower layer alkali removal pipes (1.2), each having a control valve (2.1); the upper layer alkali removal pipes (1.1) are arranged between the adjacent lower layer alkali removal pipes (1.2) in a staggered mode in the vertical direction; one end of each of the upper layer alkali removal pipes (1.1) and the lower layer alkali removal pipes (1.2) is connected to a vacuum tube (2); one end part of the vacuum tube (2) is connected to a vacuum pump (2.2); the other end of one of the upper layer alkali removal pipes (1.1) and the lower layer alkali removal pipes (1.2) is connected with a quick connector; and the quick connector is connected to a high-pressure pump through the pipe path, wherein the connection part is provided with an observation well (3) communicating with the ground. The apparatus and method disclosed by the present invention have the beneficial effects that: a structural design is reasonable and practical; the alkali removal efficiency is twice of that of a traditional method for alkali removal; and by using wind energy and solar energy directly as power, the operating cost is lowered, thereby realizing the effect of using green power to modify alkali.

Description

technical field [0001] The invention relates to the technical field of improvement devices for saline-alkali land, in particular to an improved wind-powered vacuum alkali reduction device for saline-alkali land and its use method. Background technique [0002] At present, there are mainly the following methods and methods for saline-alkali land improvement: 1. Alkali washing method, using fresh water to repeatedly pressure irrigation and drainage of alkali; 2. Dark pipe alkali drainage method; Soil improvement method. However, the implementation of the above methods cannot completely solve the problem of alkali return, especially in areas with high groundwater levels and high salinity, once there is a lack of fresh water, the ground saline-alkali water level will rise, and the land will be re-salinized and the improvement effect will be poor. [0003] However, the soil quality in most areas of our country is relatively hard, and the air permeability cannot meet the conditio...
